left shift then right shift an unsigned int
Hello, for the following code:
unsigned int var = 0xFF2277F0UL;
unsigned char take2 = (var << 8) >> 24;
Is there any pitfall about the shift? (get '22' i.e. 34 or '"' as wanted)
Thanks and best regards,
Wenjie

I don't know what your assumptions are (since you hardcoded a lot of numbers here), but if char is an 8 bit quantity, even the & 0xFF is superfluous.

(get '22' i.e. 34 or '"' as wanted) One pitfall is that it is dependent on the size of an unsigned int to get the expected results. If unsigned int holds more then 32 bits, the << 8 won't do the intended stripping. Even worse, I think it isn't clear what this code is doing. I can picture someone accidentally changing the code to: var >> 16; If I were writing the code, I'd making the stripping more explicit. (var >> 16) & 0xFF or possibly: (var & 0xFF0000) >> 16 samuel

Here's some confusion for you... <?PHP $x = (4653896912 >> 13); echo $x; ?> I ran that on two different servers.

Mouse cursor shifting left in browser
Hi All I am using Clarion 5.5 Enterprise Edition with Windows XP Home Edition. I have created a program with an ABC Browse Template. I have three relational browse boxes in the procedure. My program was working great until I downloaded the c55ee07full.zip patch. Now when I use the up or down keys to scroll through my browser, my mouse cursor shifts to the left. It also happens when I use my mouse on the browser scrollbar. With every click of my mouse button, my cursor shifts to the left forcing me to move it back to the right. If I uninstall the c55ee07full patch, returning to my Clarion 5.5 EE cd install, the problem clears up. I can also clear up the problem by unchecking the 'Enhance pointer precision' checkbox in my mouse setup in windows. I am about to relaese my program but I am afraid I will get a lot of phone calls about the problem, thus hurting my sales. Does someone know howto fix this without telling every customer to disable the 'Enhance pointer precision' option.

samsung 710v console shifted left
Hello Folks, I've just connected a Samsung SyncMaster 710v and it works fine with X. However, at boot up and in console mode it misses out the first three characters of every line.

Any suggestions as to where to look for a > cure? Sure. Use the monitor's front panel controls to shift the image to the right. The monitor should remember your settings for that combination of resolution/refresh rate...which is likely different from the resolution and refresh rate you use in X (unless you're running a high resolution framebuffer console or very low resolution in X) so you shouldn't have a problem. That's the way it works on my Samsung SyncMaster 760V. That worked a treat -- thanks! Peter ...
C and MISRA, blues... (arithmetic shifts)
I'm currently rewriting some numerical code for MISRA compliance. Signed shifts are not defined by the C-standard, and the code-checker complaints. Well - no big surprise here. I knew that and did it nevertheless. Now I have to rewrite. But do you do if you need them anyway? I need *lots* of them, so in despair I've just created this monster of unreadable code: int ArithmeticShiftRight (int value, unsigned int shift) { if (shift) { /* Get unsigned version of value to work with */ unsigned int x = (unsigned int) value; /* replicate the sign-bit of value into all bits of SignMask: */ unsigned int SignMask = ((unsigned int) -(value < 0)); /* assemble the arithmetic shift from two unsigned shifts. */ x = (x>>shift)|(SignMask<<(32-shift)); /* writeback result as signed integer */ value = (int) x; } return value; } I just had the urge to share this huge wtf code with you. It's horrible. It's unreadable, and all it does is doing a stupid shift. Has anyone here seen a C-compiler that does something different than arithmetic shifts on signed integers in the last 20 years? I've used a lot of compilers over the years, and they all shifted arithmetic.

Regarding Left shift operator in embedded processor
Respected Experts, Iam RaviKumar.N, Iam using Intel-386EX embedded processor for one of my application also Iam using a cross compiler for the execution of my code. I have a query regarding left shift operator. Consider the following variables: 1) unsigned char a = 2; 2) unsigned char b = 3; 3) unsigned short c; Consider the following expression: c = (unsigned short)(( a << 8) | b); My query is: "Is it valid to shift a byte value by an 8-bit". I got this expression compiled,but Iam not sure about the results I got. Please let me know about this.

Detecting shift key with left mouse button
Is there any way in SCL to detect that the shift key was held down while the left mouse button was clicked on an object (e.g. a container box)? LMB (or Shift+LMB) is not something that can be set in a KEYS window because the left mouse button is reserved by SAS. So there doesn't seem to be a way to do this by defining a command in the KEYS entry. Any other way? ...
Re: Detecting shift key with left mouse button
You are right, that's not so easy. If you are running Windows, you can make a call to an external DLL to see if a shift button is pressed when a container box is selected, something like this in SCL: init: control label; return; container1: /* the container box code */ shift_pressed=(modulen('GetKeyState',16)<0); lmb_pressed=(modulen('GetKeyState',1)<0); return; The lmb_pressed variable will only be set when the mouse button is held down, not when it is released. But probably things will work well enough if you just look at the shift_pressed value, and possibly combine it with the SAS SCL function LASTKEY(), which should return zero (meaning that none of the definable keys/buttons were pressed). You will have to define the DLL module in a SASCBTBL fileref, which should contain something like this (and maybe other modules): routine GetKeyState minarg=1 maxarg=1 stackpop=called callseq=byvalue module=USER32 returns=short; arg 1 num format=ib4.; You can find documentation for the GetKeyState function at http://msdn.microsoft.com/en-us/library/ms646301(VS.85).aspx, and values for the various keys and buttons at http://msdn.microsoft.com/en-us/library/ms645540(VS.85).aspx Regards, Søren On Tue, 24 Feb 2009 13:51:56 -0500, Lorne Klassen <lk1@ROGERS.COM> wrote: >Is there any way in SCL to detect that the shift key was held down while >the left mouse button was clicked on an object (e.g. a container box)? > &...
no warning for assigning unsigned int to plain int

shift regester
I want to use a shift register to incremnt a value by 0.5 every time through a for loop. However, I do not want the value on the shift regester to start at 0 I want it to start at a user defined value. How do I get it to start at a user defined value and then increment by 0.5 from there? I can do the incrementing part, just not the addition at the start. If there is a better way to do this than shift registers, I would be up for that as well. thanks Hi Musser, You can wire a constant or a control to the shift register from out side the loop to give it a predefined start value. Infact, you should always wire at least a constant otherwise the shift register may contain undesired value in the beginning. For example, if you run the loop for a second time, the previous end value will be still present at the shift register. If you do not clear it, that becomes the first value for the second loop and so on. Hope it helps, Deepu.

unsigned int
I have mysql database for internal computer evidence and I store IP as unsigned numeric value. It is very good for computing network ranges and so on. But PHP do not support unsigned integer. So when I store values to doatabase, I must convert it to string with sprintf. When reading it, I get a string value with 10-digit number, bigger than maxint. I need to convert it to signed int and work with it as a number (for making binary arithmetics). I have discovered no way how to do it. Intval() or (int) type conversion returns maxint. Converting it in mysql is anoying too, because mysql cant do signed 32-bit int type conversion, only 64 bit.

SHIFT Is Unchangeable
I learn that Intel is not willing to fix SHIFT problem on Pentium 4 since 486DX through Pentium 3 are doing fine. Do you complain that SHIFT wants to steal 4-6 cycles on Pentium 4? Intel must have reasons to leave SHIFT unchangeable because they think best to do with their budget. It is really nonsense. Do you wish to wait until year 2007 before Pentium 4 will become available at 20GHz? Would you be satisifed that SHIFT's 4-6 cycles remain unchangeable on 20GHz? If Intel changes their mind and fix SHIFT that should cost only one cycle instead of 4-6 cycles on 20GHz. It would be over 100-1000 times faster like RISC's SHIFT. I want to show you C++ example by using SHIFT and pointer. If SHIFT is used before C++ is compiled into machine language. It will run faster on Pentium 3, but it will run slower on Pentium 4. It is very annoying that I have to modify C++ code in order to run faster on Pentium 4 than Pentium 3. It does not do good. I try to tell C/C++ programmers to avoid SHIFT and use pointer instead. I create one 32 Bits variable and four pointer variables. Four pointer variables link or point to one 32 Bits variable. Each pointer variable is 8 Bits. In fact is that only ONE variable is created. Pointer is not REALLY variable. Look at my example below. unsigned int AA = 0; unsigned char* const AA_Byte1 = (unsigned char*)&AA; unsigned char* const AA_Byte2 = (unsigned char*)&AA + 1; unsigned char* const AA_Byte3 ...

Left and Right arrows
Hi, In recently recieved some excellent advice which ebnabled me to make a form behave as a spreadsheet with respect to the down and up arrow keys. To develop this further I would like the right and left arrow to move to the next or previous tab control. DoCmd.GotoRecord,,AcNext does the business for down, but nowhere can I find a 'docmd go to next tab' or words to that effect!!! Any ideas? Hum, I assume when you say "tab", you are talking about a tab control? I would not take away the left/right arrow keys...as then how can a user edit data in a field? They need the arrow keys to move within that field. If the whole field is highlighted when the cursor enters..then you can normally use the left/right arrows to move to the next/previously control (is this what you are asking for now???). However, if a users is actually typing/editing data in a control..then they need the left right arrow keys for editing. I don't think it is a very good idea to steal those keys, as then how can a user edit text in a field? You can usually hit ctrl-TAB to jump to the next tab. Also, perhaps ctrl-right arrow, and ctrl-left arrow might be a possible keys to use..but I can't see stealing the left/right arrow keys. To steal the ctrl-right/ and left key, you can add the following code to your keydown handler: Dim intTabCount As Integer Const TabMax As Integer = 1 ' max number of tabs (less 1, since this is zero...

"Not supported" has different consequences depending on the widget and the underlying platform toolkit. For read-only widgets there are platform specific work-arounds and on some native controls (like menus on Windows and Mac OS X) it just works automatically. You may want to look into gnocl, the Tcl binding for the Gnome toolkit. Gnome is supposed to support bidi fine.

Here's some confusion for you... <?PHP $x = (4653896912 >> 13); echo $x; ?> I ran that on two different servers. Server A gave me: 43814 Server B gave me: 568102 I have been hacking away and researching this for hours. I am completely clueless. Any suggestions or workarounds? Thanks in advance.

Mouse cursor shifting left in browser
Hi All I am using Clarion 5.5 Enterprise Edition with Windows XP Home Edition. I have created a program with an ABC Browse Template. I have three relational browse boxes in the procedure. My program was working great until I downloaded the c55ee07full.zip patch. Now when I use the up or down keys to scroll through my browser, my mouse cursor shifts to the left. It also happens when I use my mouse on the browser scrollbar. With every click of my mouse button, my cursor shifts to the left forcing me to move it back to the right. If I uninstall the c55ee07full patch, returning to my Clarion 5.5 EE cd install, the problem clears up. I can also clear up the problem by unchecking the 'Enhance pointer precision' checkbox in my mouse setup in windows. I am about to relaese my program but I am afraid I will get a lot of phone calls about the problem, thus hurting my sales. Does someone know howto fix this without telling every customer to disable the 'Enhance pointer precision' option.

Any suggestions as to where to look for a > cure? Sure. Use the monitor's front panel controls to shift the image to the right. The monitor should remember your settings for that combination of resolution/refresh rate...which is likely different from the resolution and refresh rate you use in X (unless you're running a high resolution framebuffer console or very low resolution in X) so you shouldn't have a problem. That's the way it works on my Samsung SyncMaster 760V. That worked a treat -- thanks! Peter ...
C and MISRA, blues... (arithmetic shifts)
I'm currently rewriting some numerical code for MISRA compliance. Signed shifts are not defined by the C-standard, and the code-checker complaints. Well - no big surprise here. I knew that and did it nevertheless. Now I have to rewrite. But do you do if you need them anyway? I need *lots* of them, so in despair I've just created this monster of unreadable code: int ArithmeticShiftRight (int value, unsigned int shift) { if (shift) { /* Get unsigned version of value to work with */ unsigned int x = (unsigned int) value; /* replicate the sign-bit of value into all bits of SignMask: */ unsigned int SignMask = ((unsigned int) -(value < 0)); /* assemble the arithmetic shift from two unsigned shifts. */ x = (x>>shift)|(SignMask<<(32-shift)); /* writeback result as signed integer */ value = (int) x; } return value; } I just had the urge to share this huge wtf code with you. It's horrible. It's unreadable, and all it does is doing a stupid shift. Has anyone here seen a C-compiler that does something different than arithmetic shifts on signed integers in the last 20 years? I've used a lot of compilers over the years, and they all shifted arithmetic.

Regarding Left shift operator in embedded processor
Respected Experts, Iam RaviKumar.N, Iam using Intel-386EX embedded processor for one of my application also Iam using a cross compiler for the execution of my code. I have a query regarding left shift operator. Consider the following variables: 1) unsigned char a = 2; 2) unsigned char b = 3; 3) unsigned short c; Consider the following expression: c = (unsigned short)(( a << 8) | b); My query is: "Is it valid to shift a byte value by an 8-bit". I got this expression compiled,but Iam not sure about the results I got. Please let me know about this.

Detecting shift key with left mouse button
Is there any way in SCL to detect that the shift key was held down while the left mouse button was clicked on an object (e.g. a container box)? LMB (or Shift+LMB) is not something that can be set in a KEYS window because the left mouse button is reserved by SAS. So there doesn't seem to be a way to do this by defining a command in the KEYS entry. Any other way? ...
Re: Detecting shift key with left mouse button
You are right, that's not so easy. If you are running Windows, you can make a call to an external DLL to see if a shift button is pressed when a container box is selected, something like this in SCL: init: control label; return; container1: /* the container box code */ shift_pressed=(modulen('GetKeyState',16)<0); lmb_pressed=(modulen('GetKeyState',1)<0); return; The lmb_pressed variable will only be set when the mouse button is held down, not when it is released. But probably things will work well enough if you just look at the shift_pressed value, and possibly combine it with the SAS SCL function LASTKEY(), which should return zero (meaning that none of the definable keys/buttons were pressed). You will have to define the DLL module in a SASCBTBL fileref, which should contain something like this (and maybe other modules): routine GetKeyState minarg=1 maxarg=1 stackpop=called callseq=byvalue module=USER32 returns=short; arg 1 num format=ib4.; You can find documentation for the GetKeyState function at http://msdn.microsoft.com/en-us/library/ms646301(VS.85).aspx, and values for the various keys and buttons at http://msdn.microsoft.com/en-us/library/ms645540(VS.85).aspx Regards, Søren On Tue, 24 Feb 2009 13:51:56 -0500, Lorne Klassen <lk1@ROGERS.COM> wrote: >Is there any way in SCL to detect that the shift key was held down while >the left mouse button was clicked on an object (e.g. a container box)? > &...

shift regester
I want to use a shift register to incremnt a value by 0.5 every time through a for loop. However, I do not want the value on the shift regester to start at 0 I want it to start at a user defined value. How do I get it to start at a user defined value and then increment by 0.5 from there? I can do the incrementing part, just not the addition at the start. If there is a better way to do this than shift registers, I would be up for that as well. thanks Hi Musser, You can wire a constant or a control to the shift register from out side the loop to give it a predefined start value. Infact, you should always wire at least a constant otherwise the shift register may contain undesired value in the beginning. For example, if you run the loop for a second time, the previous end value will be still present at the shift register. If you do not clear it, that becomes the first value for the second loop and so on. Hope it helps, Deepu.

unsigned int
I have mysql database for internal computer evidence and I store IP as unsigned numeric value. It is very good for computing network ranges and so on. But PHP do not support unsigned integer. So when I store values to doatabase, I must convert it to string with sprintf. When reading it, I get a string value with 10-digit number, bigger than maxint. I need to convert it to signed int and work with it as a number (for making binary arithmetics). I have discovered no way how to do it. Intval() or (int) type conversion returns maxint. Converting it in mysql is anoying too, because mysql cant do signed 32-bit int type conversion, only 64 bit.

SHIFT Is Unchangeable
I learn that Intel is not willing to fix SHIFT problem on Pentium 4 since 486DX through Pentium 3 are doing fine. Do you complain that SHIFT wants to steal 4-6 cycles on Pentium 4? Intel must have reasons to leave SHIFT unchangeable because they think best to do with their budget. It is really nonsense. Do you wish to wait until year 2007 before Pentium 4 will become available at 20GHz? Would you be satisifed that SHIFT's 4-6 cycles remain unchangeable on 20GHz? If Intel changes their mind and fix SHIFT that should cost only one cycle instead of 4-6 cycles on 20GHz. It would be over 100-1000 times faster like RISC's SHIFT. I want to show you C++ example by using SHIFT and pointer. If SHIFT is used before C++ is compiled into machine language. It will run faster on Pentium 3, but it will run slower on Pentium 4. It is very annoying that I have to modify C++ code in order to run faster on Pentium 4 than Pentium 3. It does not do good. I try to tell C/C++ programmers to avoid SHIFT and use pointer instead. I create one 32 Bits variable and four pointer variables. Four pointer variables link or point to one 32 Bits variable. Each pointer variable is 8 Bits. In fact is that only ONE variable is created. Pointer is not REALLY variable. Look at my example below. unsigned int AA = 0; unsigned char* const AA_Byte1 = (unsigned char*)&AA; unsigned char* const AA_Byte2 = (unsigned char*)&AA + 1; unsigned char* const AA_Byte3 ...

Left and Right arrows
Hi, In recently recieved some excellent advice which ebnabled me to make a form behave as a spreadsheet with respect to the down and up arrow keys. To develop this further I would like the right and left arrow to move to the next or previous tab control. DoCmd.GotoRecord,,AcNext does the business for down, but nowhere can I find a 'docmd go to next tab' or words to that effect!!! Any ideas? Hum, I assume when you say "tab", you are talking about a tab control? I would not take away the left/right arrow keys...as then how can a user edit data in a field? They need the arrow keys to move within that field. If the whole field is highlighted when the cursor enters..then you can normally use the left/right arrows to move to the next/previously control (is this what you are asking for now???). However, if a users is actually typing/editing data in a control..then they need the left right arrow keys for editing. I don't think it is a very good idea to steal those keys, as then how can a user edit text in a field? You can usually hit ctrl-TAB to jump to the next tab. Also, perhaps ctrl-right arrow, and ctrl-left arrow might be a possible keys to use..but I can't see stealing the left/right arrow keys. To steal the ctrl-right/ and left key, you can add the following code to your keydown handler: Dim intTabCount As Integer Const TabMax As Integer = 1 ' max number of tabs (less 1, since this is zero...

"Not supported" has different consequences depending on the widget and the underlying platform toolkit. For read-only widgets there are platform specific work-arounds and on some native controls (like menus on Windows and Mac OS X) it just works automatically. You may want to look into gnocl, the Tcl binding for the Gnome toolkit. Gnome is supposed to support bidi fine.
