Refs to controls on tab control
I'm really stumped. I have been able to get all of my references to all my controls with property nodes - even controls inside clusters for all of the controls on a vi front panel. However, when I move these very same controls onto a tab control&nbsp;I can't seem to figure out how to get these same&nbsp;references! I can only get the tab control ref. :smileyindifferent: &nbsp; &nbsp; <img src="http://forums.ni.com/attachments/ni/170/243049/1/Cotrols%20on%20pages.JPG"> BenMessage Edited by Ben on 04-20-2007 05:01 PM Cotrols on pages.JPG: http://forum...

Is a control member of a Collection of controls?
Hi all: I would like to know in run-time if a control is a member of a control collection or not.

Syntax of control on tab controls
I have a form "frmturnover" on which there is asubform "subfrmturnover" which has three tabcontrols say Page1, Page2 and Page3. There is control "control2" on Page2 that when its is entered I want to check if it is the same value as a control "control1" on Page1 and then show a pop up box if they don't match. I can work out the code for the message box but I'm getting a little lost on the syntax for referring to the controls on the pages of the tab control. I also want to check the value of Control2 on page2 with the vale of control3 on a page1 o...

How do I use a LabView control element as ActiveX Control in another application?
I am was trying to include some simple ActiveX Controls(sliders, buttons) in my VBScript. It worked with other ActiveX Components from the web, however I wasn't able to include the LabView ActiveX Controls because I was missing the necessary IDs. Moreover I was able to test the LabView control by inserting it into the VC++- Test Container. But I still can't find the necessary IDs... I don't believe that any of the LabVIEW controls (except for 3D Graphs) are ActiveX controls so I'm not sure what control you were able to insert into the VC++ container. What's the exact name ...

Treeview control and locking up other controls?
It's difficult to know to which ng to post this. It's a message that's been floating around, out there, with the typical '1 message in thread'. So, maybe nobody still knows - maybe not even a Microsfoft, itself. And this seems a fairly obscure problem, though I have seen others post with exactly the same symptoms. A treeview control is used in a subform. The treeview subform is in a tab control. And the tab control is in a subform. The treeview subform has a textbox (used to create new categories). The rest of the form has other subforms. Some of these, and the 'paren...

Control/Indicator descriptions are not imported or checked from LabVIEW to NI RG when they are placed on Tab controls

Tab Control and Rectangle Hiding Controls
I'm trying to change the back colour of a tab control in Access 2010 by using a rectangle. I've selected the tab control (not an individual page) and pasted the rectagle (solid with required colour). I then send the rectangle to the back and then the tab control to the back. The problem is that most (but not all controls remain hidden) on each tab. Subform and list boxes are visible, but labels and text boxes aren't. I've done this before in another application, but can't remember how I did it. Any ideas? -- Bob Darlington Brisbane On Thursday, June 20, 2013 1:57:59 AM UTC-5, Bob Darlington wrote: > I'm trying to change the back colour of a tab control in Access 2010 by > > using a rectangle. > > I've selected the tab control (not an individual page) and pasted the > > rectagle (solid with required colour). > > I then send the rectangle to the back and then the tab control to the back. > > The problem is that most (but not all controls remain hidden) on each tab. > > Subform and list boxes are visible, but labels and text boxes aren't. > > I've done this before in another application, but can't remember how I did > > it. > > Any ideas? > > > > -- > > Bob Darlington > > Brisbane Not sure I understand your issue.

control file .ctl and control characters
Hi all, I'm loading a data file into a temp table using SQL Loader. One of the columns is a date type field. However, in the data file there is sometimes a series of control characters like '' in the date fields. This is causing problems as all those records are getting bumped to the bad.file. I tried to use a nullif but that is not working either. Its okay if the field is blank because when i update the data from the temp table to the target update table i'll use the TRIM function. Here is the control file LOAD DATA INFILE 'C:\testfile.dat REPLACE INTO TABLE testtable ( varcol1 POSITION(01:01), varcol2 POSITION(02:16), charcol1 POSITION(17:27), charcol2 POSITION(28:107), charcol3 POSITION(108:109), datecol1 POSITION(110:119) date nullif (datecol1 =3D '') ) Any help would be greatly appreciated.

Control texbox or label with VScroll control
Hello all. I am pretty sure i saw a relevant post some time ago in the ng, but did not save it somewhere. Anyway, my problem is as follows, I have data from an Access base to be shown (in 5 textboxes or 5 label controls - it does not matter) and i want them to be scrolled. I plan to "break" each record from the base into 5 parts and show them separately. So, each scroll click should move all 5 lines so the visual of the 5 of them is as one single line. I would like to avoid Grid control or any similar because 1) i have no idea how to use it, and 2) i was planning to have as few a...

Move from SCSI Controller to RAID Controller

Do you know of a utility that would enable to move data from a single SCSI drive to a RAID Array without having to back up the data to a CD, Tape or Server ?

Finding control type from control reference
I have a stric type control (A) on the front panel of a VI. This control is a cluster made up of a number of instances of another strict typed control (B). Later control (B) is also a cluster made up of two controls, a check box and an enum. In the VI there is a value change event handler for control A. (I have included the check box to conrol B, it previously had only the enum). There is existing code in that event handler that works on the enum control. When I check a box, event handler is called and it tries to detect which enum's value has been changed. Since none has been changed, it ...
