When I press a button I open a PDF, BUT PDF opens under dialog, how can I do?

In my program I have a dialog and when I press a button PDF opens, but PDF opens under dialog, so I can't see it, I would like see PDF in the foreground

What I have tried:

I used

ShellExecute(NULL, _T("open"), str_FilePathPDF, NULL, NULL, SW_SHOWNORMAL);

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with. And I have no idea at all what you mean by "BUT PDF opens under dialog".

ok, I hope this question is clear

I just tried that and the PDF was opened in the foreground, hiding the dialog. You need to provide more information.

if I WRITE
bool b = this->GetForegroundWindow(), b is true, so how I can put false setForegroundWindow? For my dialog I mean

You should not need to do that. As I said, I have tried it (twice in fact), and the PDF always becomes the foreground window.

Member 14594285 5-Aug-21 6:10am

I understand but in my case it doesn't work, so I must find an alternative method

Richard MacCutchan 5-Aug-21 6:13am

Well before you do that you need to find out why it is not working. As that is the only way to be reasonably sure that your alternative will correct the problem.

Member 14594285 6-Aug-21 5:48am

is there an option relative to the dialog where I decide if dialog is in the foreground?

Richard MacCutchan 6-Aug-21 6:38am

Dialogs will always open in the foreground. Modal dialogs block the main window of the application that shows it. But there should not be any need to play with foreground settings, the system is designed to maximise the user experience.

I know but I don't understand because I have this problem, maybe there is an option f dialog

Richard MacCutchan 6-Aug-21 9:11am

I understand that. But until you can find out why this problem is happening, you will not be able to find out how to fix it. And as I told you yesterday, I have tried this with a simple Dialog application, and a full Windows application that shows a modal Dialog, and in both cases the PDF viewer was launched into the foreground.

Member 14594285 6-Aug-21 10:07am

I found out that option topmost of the dialog is the cause, so, like I said before, it depended on option of dialog

Richard MacCutchan 6-Aug-21 10:23am

Perhaps if you had mentioned that in the first place ...

And why do you think you need it?
