Title: Command Button Caption Change
Post by: Marc van Cauwenberghe on October 15, 2008, 10:12:02 AM

I can change the button caption, but it doesn't actually change until I move the mouse over it..

Can I force the change?

I was thinking redraw, but didn't know if that is the best tack to take.

Do you mean at design time (within the FireFly IDE) or run time (when your application is actually executing)?

If it is during runtime then there is something else in your code that is preventing control updates. Can you post the code where you are updating the caption? I have never encountered a situation where FF_Control_SetText does not update the caption immediately.

I used the control redraw to force the update..

I assume this is the preferred method.

Hi Jim,

Yes, I guess FF_Control_Redraw would work because it simply applies a paint tot he control. Likewise, you could send the specific RRButton message, %RBM_REFRESH, to do the same thing.

i.e.
SendMessage hWndControl, %RBM_REFRESH, 0, 0

I am finding I need to seperate lines in order to compile...
No biggie, but I was wondering.. BTW the more I use FF the better I like it.. :D
I find that I must put an empty line after the FF_TextBox_SetText command.

This statement generates an error
    If IsFalse Len(FF_TextBox_GetText (HWND_FORM1_TXTPC)) Then
     FF_TextBox_SetText (HWND_FORM1_TXTPC, "Select Profile")_As_Long
End If
Error Number = 455... End IF Expected....

This does not..

If IsFalse Len(FF_TextBox_GetText (HWND_FORM1_TXTPC)) Then

     FF_TextBox_SetText (HWND_FORM1_TXTPC, "Select Profile")_As_Long

End If

Hi Jim,

You must be using the F8 code function popup to insert the prototype for the FF_TextBox_SetText function. When you do that, you must edit it a little bit. For example at the end of the string is "_As_Long". You need to get rid of that when you use it in code. It is there just to remind you that the function returns a Long result.

Code Select


FF_TextBox_SetText (HWND_FORM1_TXTPC, "Select Profile")_As_Long

to:

Code Select


FF_TextBox_SetText (HWND_FORM1_TXTPC, "Select Profile")  

- or -

FF_TextBox_SetText HWND_FORM1_TXTPC, "Select Profile"
