.c and .uir files behaving erratically

[John Nordling]

I wrote a program a while back to control some instruments and yesterday I went in to make a couple small changes (install a popup window as the program starts). After I was finished, as near as I can tell, the source code and the .uir were no longer "in synch" as certain commands were updating the wrong variables in the .uir file. For example, one of the control buttons is supposed to be dimmed when another button is pressed, but instead a totally unrelated control was dimmed. I fixed it by copying one of the controls in the .uir file, pasting it, saving over the old .uir, deleting the new control and saving again. I don't really understand what happened or why this should have worked. Has anyone else out there experienced anythi
ng similar, and do you understand what happened? I'm pretty much teaching myself programming as I go, so any input would be much appreciated.

Hello John,

I imagine that you were using the SetCtrlAttribute function to dim the button. In that function, the "Control ID" field is where you specify a defined constant, located in the .uir header file, which you assigned to the control in the User Interface Editor. By pressing the enter key while your curser is in this field, a list of constants from your header file will pop up to select from.

You can change the name of your controls on the UIR by right clicking on a control and choosing Edit Control (or by selecting the control and going to Edit >> Control..., or by selecting the control and pressing the enter key). The constant in the header file will be "PANEL_" and the name specified in the Constant Name filed appended to the end of it.

Good luck
with your programming. I hope that everything goes well. Take care and have a great day.
