Re: Removing and adding Caption Bar of a dialog at runtime

13-Sep-07 1:26

Can anybody help me help me to remove and add Caption Bar of a dialog at runtime.

I have created a dialog through resource with a caption bar.

I want to remove completely the caption on clicking the Button1 on the dialog and add the caption bar on click of button2 on the dialog.

Though on click of Button1 the caption bar is still there but the dialog is not movable whereas when i click Button2 I am able to move the dialog on selecting the Caption bar.

Can anybody suggest the way where the caption will be completely removed and caption appears as per our requirement.

void CCaptionWndDlg::OnButton1()
{

ModifyStyle(WS_BORDER|WS_CAPTION,0);

CRect aRect;
GetWindowRect(&aRect);

::SetWindowPos(m_hWnd,HWND_TOP,aRect.top,aRect.left,aRect.Width(),aRect.Height(),SWP_NOZORDER | SWP_NOACTIVATE);

}

void CCaptionWndDlg::OnButton2()
{
ModifyStyle(0, WS_BORDER|WS_CAPTION);

CRect aRect;
GetWindowRect(&aRect);
::SetWindowPos(m_hWnd,HWND_TOP,aRect.top,aRect.left,aRect.Width(),aRect.Height(),SWP_NOZORDER | SWP_NOACTIVATE);

}

replace with

::SetWindowPos( m_hWnd, 0,0,0,0,0, SWP_NOSIZE|SWP_NOMOVE|SWP_NOZORDER|SWP_DRAWFRAME );

FYI: SWP_DRAWFRAME can be specified in the ModifyStyle itself

Ya I forgot. BTW ModifyStyle() internally does the same thing...

The following code will do the trick... Smile | :)

void CCaptionWndDlg::OnButton1() 
{
    ModifyStyle( WS_BORDER | WS_CAPTION, 0, SWP_DRAWFRAME );
}

void CCaptionWndDlg::OnButton2() 
{
    ModifyStyle( 0, WS_BORDER | WS_CAPTION, SWP_DRAWFRAME );
}

SWP_DRAWFRAME can be specified in the ModifyStyle itself. So no need to call SetWindowPos explicitly. See the MSDN documention for more details. Smile | :)

How to get information about installed codecs ...

... or supported MIME-Types?

I try to code a tiny Multimedia-App (which also uses DirectShow). For error handling, i need to know something about the capabilities of the desired Viewer (supported Audio- / Videocodecs). Any idea, how to get a list of installed codecs on the local machine? I dont know where to look :-|

Hints are very welcome :-|

I think you should be able to know installed software (i.e. codecs) through browsing in the registry. I can help you much more, bit if you look "registry" in the forum you will find a lot of interestan messages that maybe give you ideas.

hope it helps.

You might be running the unicode version.

change the following option in msdev

tools->options->Debug tab->Tick "Display unicode strings".
