I want to move one control over the top of another; the objective being that only one of the controls will be displayed (in the same place) depending upon possible modes of operation. In the following code all I want to do is move the IDC_GAINSLIDE control up on the y axis to the same position as the IDC_AGCTIMECONST control. It will remain in the same x axis position and retain its size. In the following code the window coordinates obtained via GetWindowRect are:
src.left 332, (IDC_AGCTIMECONST window)
src.top 103,
targ.left 332, (IDC_GAINSLIDE window)
targ.top 143
CRect src, targ;
pCtrl = GetDlgItem(IDC_AGCTIMECONST);
pCtrl->GetWindowRect(&src);
pCtrl->ShowWindow(SW_HIDE);
pCtrl = GetDlgItem(IDC_GAINSLIDE);
pCtrl->GetWindowRect(&targ);
pCtrl->SetWindowPos(NULL, targ.left, src.top, 0, 0, SWP_NOSIZE | SWP_NOZORDER | SWP_SHOWWINDOW);
Nothing happens to the position of the IDC_GAINSLIDE control when I do the above. However when I change the 3rd (y) parameter of SetWindowPos to 'src.top-60' the IDC_GAINSLIDE window is moved up to pretty much where I want it. I must be missing something obvious but I can't see it. Any ideas?
Thanks,
Wayne King

Going back to your actual initial specification - you want to bring one of a pair of windows to the top of the local z-order, so you can only see the "chosen one"...
Assuming they're both created at the same place, why can't you do...
BOOL CMyDlg::ChangeMode (int nMode)
{
CWnd *wndMode = LookupWindowFromModeSomehow (nMode);
return wndMode->>SetWindowPos (&wndTop, 0,0,0,0, SWP_NOMOVE | SWP_NOSIZE);
}
?

I have MFC dialog application. How can I write something to current console when it is ecexuted by "cmd"? It seems AllocConsole() creates new console which is closed after program exit.
Thank you.

What about AttachConsole()?

It requires Windows Vista or Windows XP. I'd like to have it running on Win98 too.

Sorry. I must've missed that requirement in your initial post.

Hi all,
I am trying to allocate memory of more than 2GB using the system boot flag /3G and also i set the linker option /LARGEADDRESSAWARE. This should let me have atmost 3GB of allocation. After doing that, i try allocating slighly more memory than 2GB
BYTE* m_pDIB = (BYTE *)VirtualAlloc(NULL, (size_t)0x81000000, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);
UINT32 ui32Err = GetLastError();
printf("\nVirtualAlloc(NULL, (size_t)0x81000000, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE); Results: Address is %Xh and error is %d", m_pDIB, ui32Err);
I have also set the system virual memory(swap) to have bigger size than 3GB.
The error code returned is ERROR_NOT_ENOUGH_MEMORY with the VirtualAlloc returning NULL.
Any help in this regard would be greatly appreciated.
Best regards,
RUI

There has to be 2GB of contiguous memory available.

Why the hell would you allocate soooo much memory

Yes i have increased the virtual memory to 15 GB now but this still does not work 
I am trying using the code given below:
BYTE* m_pDIB = (BYTE *)VirtualAlloc(NULL, (size_t)0x81000000, MEM_COMMIT | MEM_RESERVE | MEM_TOP_DOWN, PAGE_READWRITE);
UINT32 ui32Err = GetLastError();
printf("\nVirtualAlloc(NULL, (size_t)0x81000000, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE); Results: Address is %Xh and error is %d", m_pDIB, ui32Err);
m_pDIB = (BYTE *)VirtualAlloc((LPVOID)0x81000011, 0x100, MEM_COMMIT | MEM_RESERVE | MEM_TOP_DOWN, PAGE_READWRITE);
ui32Err = GetLastError();
printf("\nVirtualAlloc(LPVOID(0x81000000), 0x1000, MEM_COMMIT | MEM_RESERVE | MEM_TOP_DOWN, PAGE_READWRITE); Results: Address is %Xh and error is %d", m_pDIB, ui32Err);

Hi all,
I want to enable Auto logon feature through my application. I got help for doing so manually from the below link.
http://support.microsoft.com/kb/315231[^]
But if i try to do it programmatically then i am not being succeeded in that. I made all three registry entries(AutoAdminLogon, DefaultUserName, DefaultPassword) correctly through programming as mentioned in manual steps in above link. If i do it manually it works.
But somehow it is not happening. can anyone please throw some light on this? It would be a great help to me. Please help me out.
Thanks
Hemang

When you add those value through code, can't you just open the registry and see if they are correct? The registry does not care how keys and values are created. If they are correct, something else other than your code is wrong.

For urgent questions key plz into Google. For 'smoothing algorithm' you might try Googling for 'smoothing algorithm' or even for Bezier. Good Luck.

how create a shortcut key of each button control mfc code
|
|
|
|
|
Put an ampersand (&) character before the shortcut key you want in the button's text.
For example: "&Cancel". 'C' is the shortcut key, and the button with this text can be invoked with Alt-C. The ampersand won't be displayed.
