Question

Im trying to get a CDialog that has no border or frame to show in the task bar.

It is created in the InitInstance of CWinApp (used to update the app) and i have tried setting the WS_EX_APPWINDOW flag but it still doesnt show in the task bar.

Any ideas?

Edit:
As defined in the resource:

IDD_UPDATEFORM_DIALOG DIALOGEX 0, 0, 246, 124
STYLE WS_POPUP
EXSTYLE WS_EX_APPWINDOW
FONT 8, "MS Shell Dlg", 400, 0, 0x1
BEGIN
END

As used:

 UpdateForm *dlg = new UpdateForm(UPDATE_FILES, CWnd::GetDesktopWindow());
 INT_PTR nResponse = dlg->DoModal();


UpdateForm::UpdateForm(int updateType, CWnd* pParent) : CDialog(IDD_UPDATEFORM_DIALOG, pParent)
{
 m_bInit = false;
 m_hIcon = AfxGetApp()->LoadIcon(IDI_ICON);
 m_Progress = new DesuraProgress();
 m_updateType = updateType;
}

Still Shows up like so:

I figured out a hack to get this to work. Instead of disabling the toolbar/caption bar styles to get no border, i used SetWindowRgn to clip the frame and title bar. Same affect, less issues.

RECT rect;
GetWindowRect(&rect);
int w = rect.right - rect.left;
int h = rect.bottom - rect.top;

HRGN region = CreateRoundRectRgn(5, 30, w-5, h-5-30, 5, 5);
SetWindowRgn(region, true);
