Try using GetWindowRect (), ScreenToClient() and then MoveWindow function.

Go to project settings and check the paths of header files, and other libraries and files there. Make sure that they are correct.
I hope it helps

CLoginDlg is not a built in class. You have to write it your own. I am giving just e.g.

For example, I want to create mem dc for a client window.The client size is (100, 200) ,but i want create a larger mem dc which may be (1000, 2000),
The code lists below work well on xp but fail in 2000, why?
CDC * pDC = CreateCompatibleDC(this);
CDC m_memDC;<br />
m_memDC.CreateDC( pDC );<br />
HBITMAP hbitmap = m_memDC.CreateCompatibleBitmap( width, heigth ); <br />
May be I just can create a bitmap which size is smaller than the client window on windows 2000??
if i still want to create a larger one, how to do this?
What do you think ? Can give me some help?
thanks!!

Error 87 is "The parameter is incorrect" (Use the error lookup tool that comes with VS)
Also, I didn't realize the CDC had a CreateCompatibleBitmap() member function.
And CDC::CreateDC usually takes 4 parameters, none of them a pointer to a CDC object.
I am suprised you even get the code to compile.
You may be right
I may be crazy

Thanks!
And I'm sorry, I made a clerical error.
The code can work well on xp but failed in 2000.
I think ms may be make some improvement.
Win2000:
If I use like this,
CreateCompatibleBitmap( pDC->m_hDC, 1000, 2000 )
//the last error code is 8( not enough memory )
CreateCompatibleBitmap( m_memDC->m_hDC, 1000, 2000 )
//the last error code is 87 ( invalid parameters )
WinXp
CreateCompatibleBitmap( m_memDC->m_hDC, 1000, 2000 )
//the last error code is 0
Why I will create a bitmap which size is larger than client window?
Because I want to draw everyting on this bitmap.

// Something like this will get you to the next step...
CBitmap bmp;
CDC memDC;
CClientDC dc(this); // Will clean itself up when goes out of scope
memDC.CreateCompatibleDC(&dc);
bmp.CreateCompatibleBitmap(&dc,1000,2000);
memDC.SelectObject(&bmp);
// Add error checking, etc...
// NOTE: The CClientDC is not needed if in OnDraw
|

Thanks!
I find the problem, the parameter w that used in function CreateCompatibleBitmap(m_memDC->m_hDC, w, h) is too big, I set default value is 65535, because msdn say this parameter is a int.
It's a puzzle why I can not set the max value to this parameter, may be it out off CDC's default allocable memory.

Our app creates a main dialog window and uses SetIcon to set the taskbar icon. That works fine. Then that window creates another modeless dialog and it too uses SetIcon. The taskbar then groups the two icons, but the icon it uses is directly from the app's resource file (IDR_MAINFRAME). How can I set that (group) icon too? Interestingly I remvoed the IDR_MAINFRAME icon def from the resource file and I get a black square for the taskbar group icon!! (actually the black square only resulted after I used TweakUI to clean out the cached icons -- windows is just sooo frustrating)
Thanks for any hints on this very (typically) frustrating mfc/windows behavior!!

If your using VC++ 6.0, messing with the Resource files directly can sometimes get you some interesting artifacts on the dialogs that can be undone but it takes some trial and error jacking around. Just make sure to copy the project before making direct modifications to those resource files. My favorite artifact is the blue line mish-mash pattern.

Dear all;
I am trying to make some drawings on a dialog based application. As far as i have understood, its better to place a Static control and draw on it instead of directly drawing on top of the dialog.
As i am trying to achieve this, i am a little bit confused and gona be needing some of your help.
I have added a picture control to my dialog and created a member variable for it of type CStatic. Now I need to subclass the picture control in which i will be overriding the OnPaint() function. I do not know how to perform this subclassing  ?
Thanx

I wouldn't add a picture control, I'd add a static control and subclass that. But you have to specify that you want to receive messages by adding 'SS_NOTIFY' (or something like that) to the window's style. have a look here at my Modeler[^]
