I have a custom dialog with a BACK, NEXT, CANCEL buttons. When the cancel button is clicked, the OnCanceling() function is called. But if I try to close the dialog by clicking on X button on the top right corner, no action takes place. My code does not recognize DLG_CLOSE at all.
This is my function below..

#define SD_CUSTOM_DB_ASK_OPTIONS "DBAskOptions" #define SD_PBUT_CONTINUE 1 #define SD_PBUT_EXITSETUP 9 #define SD_PBUT_BACK 12 function NUMBER MyCustomDialog() STRING szDialogName; BOOL bDone; NUMBER nResult, nCmdValdue; begin szDialogName = "SD_CUSTOM_DB_ASK_OPTIONS"; EzDefineDialog( szDialogName, ISUSER, SD_CUSTOM_DB_ASK_OPTIONS, 0); bDone = FALSE; while (bDone=FALSE) nCmdValue = WaitOnDialog(szDialogName); switch (nCmdValue) case DLG_INIT: MessageBox("init", INFORMATION); case SD_PBUT_CONTINUE: MessageBox("continue", INFORMATION); bDone = TRUE; nReturn = NEXT; case SD_PBUT_EXITSETUP: MessageBox("cancel", INFORMATION); bDone = TRUE; nReturn = CANCEL; case SD_PBUT_BACK: MessageBox("back", INFORMATION); bDone = TRUE; nReturn = BACK; case DLG_CLOSE: MessageBox("close", INFORMATION); bDone = TRUE; nReturn = CANCEL; case DLG_ERR: MessageBox("Internal dialog box error", SEVERE); bDone = TRUE; endswitch; endwhile; EndDialog(szDialogName); ReleaseDialog(szDialogName); return nReturn; end; |
Please let me know what I am doing wrong. The "case DLG_CLOSE:" never gets executed when I click on the close button. All the other cases work fine.
Thanks,

Substitute the following code for DLG_CLOSE
case DLG_CLOSE: // The user clicked the window's close button.
Do (EXIT);
case DLG_CLOSE: // The user clicked the window's close button.
Do (EXIT);

Still, nothing happens. Actually, the execution does not reach "case DLG_CLOSE" at all even when I press the Close button on the right hand top corner.
I am sorry that I did not explain properly in my initial mail. Actually, in the code that I have provided, when I press the close button, it does not display
MessageBox("close", INFORMATION).
So, the script is actually not recognizing that I have pressed the CLOSE button.
Any help is highly appreciated.
Thanks,
Vishwa

Vishwa,
If you look at the example in the InstallShield Help for EzDefineDialog() you will see that they use a Repeat-Until bDone; loop. You are using a While-Endwhile loop.
Also, you defined a Numeric variable as nCmdValdue, but typed it in your code as nCmdValue. If you try to compile it as typed, there should be a compile warning about an undefined variable nCmdValue..
As the example in the Help file demonstrates, use
case DLG_CLOSE: // The user clicked the window's close button.
Do (EXIT);

Vishwa,
After trying the code I sent you, I have to admit that the default code to close the form does not work. That code was:
case DLG_CLOSE: // The user clicked the window's close button.
Do (EXIT);
What I discovered was that while working with the dialog 'Askpath', I noticed that the form had an invisible button in the lower left corner of the form. This button has a Name Porperty of 'ControlId_2' and a Control Identifier of '2'. So what I did was to add the lines:
#define SD_PBUT_CLOSE_FORM 2 // The invisible button on the form
case RES_PBUT_CLOSE_FORM:
MessageBox ( "CLOSE - Here I is!" , INFORMATION ); // Testing message
// The user clicked the window's close button.
Do (EXIT);
And the form responds!
I am at a loss as to why the default reserved work DLG_CLOSE does not respond directly in this version.

Hi Ozone,
Thanks a lot for your discovery. I too found the C button at the left end of my custom dialogs. I added the case to handle that button, and everything works like a charm!
Thank you once again,
Vishwa
