Question

Modeless dialog box

Asked by: kuldeep_singh_m

Hi,

I have a class derived from CDialog and I implemented it as a modeless dialog box. When I tested it earlier in Modal() state it worked fine but now it doesn't work. It seems that the controls on this dialog box are not sending the messages. I have a list box control on this dialog and whenever any selection change occur I was trapping OnSelChange() function but now after making it modeless this function is not getting called. The parent Window which creates this modeless dialog box is also derived from CDialog() but it is running as a modal.


What can be the problem???

You made a mistake, Modeless dialog don't use Modal(), you have to create() in constructor then show it, like this

AfxGetMainWnd ()->EnableWindow (FALSE);
Create (IDD_COMPILEDOWNLOAD);
ShowWindow (SW_SHOW);

you can use it :
CYourDialog dlg;

after you finished, you have to call these:
AfxGetMainWnd ()->EnableWindow (TRUE);
dlgCompDown.DestroyWindow ();

I told the dialog box worked fine when I tested it as a modal one. I know that Modeless dialog boxes have to be created by calling their create() function.

Sorry for that one.

Hi,

Can U put the code. It may help to  figure out the problem..
I tried a similar sample app and its working fine.

Regards
Ravi

Yout modeless dlg should receive messages in the same way as when running modal -- unless you are doing something unusual.

Please post code here if you want us to have any chance of solving the problem.

We'll need the code used to instantiate and create the modeless dlg and (probably) the entire code of the dlg module itself.

Hi folks,

Thanks to all of you for helping me. I solved the problem and it is working fine now. What is to be done about the points???

 

by: DanRollinsPosted on 2000-09-15 at 15:28:39ID: 4322199

I suggest giving the points to the expert who wrote the most intelligent and on-point suggestion.

I also suggest posting a brief note as to exactly what caused the problem, otherwise I will remain puzzled for many years.

Thanks to all of you guys.

Actually the resource editor created duplicate resource id's. The id of the combobox was same as that of the push button.
