Solution 1

If it is a modal dialog that is probably correct. A modal dialog makes the calling Window inactive until it is closed. So even if you minimize it there is nothing else you can do in the application.

so I can't solve this problem? is there an other option?

An other option for what? You have not explained what actual problem you are trying to solve.

I wanto to minimize my dialog

Richard MacCutchan 8-Mar-22 11:14am

We already know that. But you have not explained why; that is, as I said above, what actual problem you are trying to solve.

Member 14594285 8-Mar-22 11:19am

yes, you told me that it isn't pssible

Richard MacCutchan 8-Mar-22 11:39am

How many this must I repeat this: what actual problem are you trying to solve?

Richard had expressed the assumption that you are opening a modal dialog that cannot easily be minimized.
But we don't know what the dialog is used for, why it needs to be minimized and ultimately whether it should be a dialog at all. One might also ask why a modal dialog is used and not a non-modal one, or the other way around, why would you want to minimize it. There are many possibilities to change something here and the statement that it is not possible is not true with some certainty.

I try to explain my problem:
I have a modal dialog and then with a button I open a CDialog, if I try to minimize the second dialog it doesn't minimize...

Richard MacCutchan 10-Mar-22 10:04am

If The CDialog is opened with a call to DoModal then it is blocking the other dialog. So why do you want to minimise it? What actual problem are you trying to solve or work around?

If I wanto to minimize my software I must minimize dialog, so I can't solve it?

Richard MacCutchan 10-Mar-22 10:20am

No, you cannot minimise an application that has a modal dialog active. A dialog is used to get input from the user, so the application cannot continue until it is answered. If it was possible to minimise such an application then the system could be put in an unstable state.

Is there an event that records if I press button to minimize? so I can use SetVisible

Richard MacCutchan 10-Mar-22 11:29am

How will that help you?

Member 14594285 10-Mar-22 11:44am

With event I can make dialog visible or not visible

Richard MacCutchan 10-Mar-22 11:49am

And then you will have an active application that cannot do anything and no way of telling why. You really need to understand what modal dialogs are used for.

Member 14594285 10-Mar-22 11:55am

Yes but is there an event that records when I press button to minimize in mfc?

Richard MacCutchan 10-Mar-22 12:01pm

You could try CWnd Class | Microsoft Docs[^], but you still have the basic problem that your application cannot proceed, and if the dialog is not visible then how will you make it visible again.

And you still have not explained why you are trying to do this.
