Positioning a Dialog Box

Hi All,

I have a dialog based app..It has some buttons on it.
When I click a button, a Modal Dialog Box pops up.
Now, how do I position the Modal Dialog Box so that it is drawn over the button... ??
I want to draw the dialog boxws right over the corresponding buttons..

I have used SetWindowPos but it positions the dialog box relative to the top left of the screen.
I want to position it relative to the upper left vertex of the application's main dialog box

Hope I have clearly stated my problem Smile | :)

AbbyIndian

You need to use better coordinates for SetWindowPos then.

If you use GetDlgItem (IDC_MYBUTTON)->GetWindowRect (&rcCoords), then you'll get the button's position in screen coordinates, which you can then use in SetWindowPos for your secondary dialog.

Thanks for the response Smile | :)

But don't we have same flag or attribute setting or some other way after which we can provide relative x,y points to SetWindowPos ??

This code snippet worked fine for me:

void CMyMainDialog::OnButton1() 
{
    CMyPopupDialog dlg(&m_btn1);
    dlg.DoModal();	
}
 
BOOL CMyPopupDialog::OnInitDialog() 
{
    CDialog::OnInitDialog();
	
    CRect rc;
    m_pParent->GetWindowRect(rc); // m_pParent is a pointer to the button
    SetWindowPos(NULL, rc.left, rc.top, 0, 0, SWP_NOSIZE | SWP_NOZORDER);
	
    return TRUE;
}

Hello friends,

I am trying to built in project in Visual Studio 2005. Project is created in MFC(Application project) and Visual studio 2003 by other person.

I am getting an error while comping. The error points towards
some file comsuppwd.lib.

I am just putting error names here as follows,

error LNK2005: "class _variant_t vtMissing" (?vtMissing@@3V_variant_t@@A) already defined in comsuppwd.lib(comutil.obj)	comsuppd.lib

and other is
fatal error LNK1169: one or more multiply defined symbols found

I searched on net but not able to solve this error. please help me.

"Explicit references to comsupp.lib, either from the comment pragma or via the command line, should be changed to now use either comsuppw.lib or comsuppwd.lib, as /Zc:wchar_t is now on by default. comsupp.lib should still be used when compiling with /Zc:wchar_t-." from msdn.

try setting "vsproperty->language->Treat wchar_t as Built-in type = No". or specify the lib as above.

So, what happened when you tried that? Did it compile? Did it run? Did it give the expected result?

It compiled..It run but it did not gave expected result..
I try to find the error with the help of GetLastError and it comes to 1400 that is "Invalid window handle"

But i'm sure hPWnd is Property sheet Handle.

Do i need to pass something else??

EnableWindow(GetDlgItem(hPWnd,PSBTN_OK),FALSE);

use IDOK inplace of PSBTN_OK. and should do after the dialog is created say in WM_INITDIALOG handler.

Ashish Chauhan wrote:

It is not the hPWnd is invalid, since GetDlgItem() returns a invalid handle EnableWindow end up with error.

If you are going for modeless property sheet, you can create your own dialog box layout.

GetLastError() returned 1400 (invalid window handle), because GetDlgItem() failed. And Rajkumar has already explained why it is so. Is the problem solved now?

if you are looking for disabling APPLY button, have a look at PSM_CHANGED and PSM_UNCHANGED message.
