Oh I am Sorry .. I didnt read the question correctly .
RegEnumKey is the right answer.
Infact enumerate the following key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
you ll get the list of all Uninstable Softwares
Hope that serves

The problem given to me is to build a MFC app , which should have multiple child windows same as in a typical MDI , but all the views should be connected to single instance of Document class,
Something you can give a name Multiple Views Application,
that is one document and multiple views.
I am not suppose to use splitters where in I can create multiple views in CFrameWnd::OnCreateClien().
Does some one has a clue about how to go about >?

Override CMultiDocTemplate::OpenDocumentFile. This method is called when your app opens file from disk or creates new file. Before calling original implementation, check if any document is open and close it.

Create MDI app. When user opens/creates new document, you have to do the following:
1) ensure that previously active document is closed.
2) open additional 3 views (or whatever number is needed)
Overriden CMultiDocTemplate::OpenDocumentFile is the perfect place to put this functionality.

When creating an active document container application, is it possible to display an active document server's menu icons? The default MFC implementation does not do this, so I'm wondering if it would be possible to (re)implement some OLE interface to achieve this. Any hints would be greatly appreciated!

Hi
I'm creating a window in a specific position and need to write some text in that window area. I've used TextOut() for the same. Window is created, but the Text is not written over there.
Herez the code snippet I'm using.
/*hWnd1 = CreateWindowEx(WS_EX_TOOLWINDOW,"HelpClass",NULL,WS_POPUPWINDOW,466,140,320,94,hWnd,NULL,ghInst, NULL);
hDC=GetDC(hWnd1);
hFont = CreateFont(14,0,0,0,FW_BOLD,0,0,0,ANSI_CHARSET,OUT_DEFAULT_PRECIS,CLIP_DEFAULT_PRECIS,PROOF_QUALITY,DEFAULT_PITCH | FF_SWISS,"Century New");
hOldFont=SelectObject(hDC,hFont);
SetTextColor(hDC,BLACK);
TextOut(hDC,0,0,"Title",5);
DeleteObject(SelectObject(hDC,hOldFont));
ReleaseDC(hWnd1,hDC);
Any Help is appreciated.
TIA
Venky

Just a hunch, but you probably need to perform the Textout call in the window's WM_PAINT handler.

I think he/she meant draw white(background color) on the old one.
Also for painting with GDI+ check this

if the erase line is below another graphics, such operator may bring some unconformable result?
how i deal with it?

The point is that you have to write codes that paint ALL of
your objects in OnPiant().
I think you got your answer in Christian's reply,don't you?

That 's what i done:
Bitmap *m_image; /*for draw line, which will combined with the back ground*/
LRESULT OnMouseMove(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
if ( IsWindow() == false )
return 0;
PAINTSTRUCT ps;
// Start a paint session and create a graphics object.
BeginPaint(&ps);
Graphics *g1 = Graphics::FromImage(m_image);
g1->Clear(Color(Color::White));
Pen p(Color(255, 0, 0, 0), 5);
g1->DrawLine(&p, 0,0, LOWORD(lParam), HIWORD(lParam));
EndPaint(&ps);
//combine the line with the background
BeginPaint(&ps);
Graphics g2(GetDC());
ImageAttributes imageAttr;
Status stat = imageAttr.SetColorKey(Color::White,
Color::White,
ColorAdjustTypeDefault);
CRect rect;
GetWindowRect(&rect);
if ( !m_image )
m_image = new Bitmap(rect.Width(), rect.Height());
Rect rc;
RedrawWindow();
g2.DrawImage(m_image,
Rect(0, 0, m_image->GetWidth(),
m_image->GetHeight()),
0, 0, m_image->GetWidth(), m_image->GetHeight(),
UnitPixel, &imageAttr, NULL, NULL);
EndPaint(&ps);
return 0;
}
LRESULT OnPaint(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
{
//here i draw a picture as the background
}
it seems that i must redraw all the window when the mouse moving, thus comes with the flicker. can it be avoided?

One time I wanted do the same things and I couldn't get rid of that flikering.I didn't work enough on this subject to help you,I think it is better to ask Christian Graus about it.

If you want the picture as background of your window,paint it in OnEraseBkgnd() (WM_ERASEBKGND),that is better place for it.

If you're talking about a selection box, I would draw it direct to the graphics object in the paint method, and therefore it is never a permanent part of the image, just drawn on top of it each time.
Of course, I'd double buffer it and draw it onto the buffer image, but you get the idea.
