One solution is to limit the size of the frame to a static minimum size. That way, you will not need scrollbars.

Hi,
I've done a prog to shut down a computer after a period of time via InitiateSystemShutdown(). I got a problem in W2K -> windows shuts down and displays a messagebox: i it now safe to shut down the computer (or something like that). Is there any possibility to make w2k power down the system ? I got this problem only in w2k, w9x and xp works fine, nt4 not tested.

I have been using this.. put this in one of you .h files..
BOOL MySystemShutdown()
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;
if (!OpenProcessToken(GetCurrentProcess(),
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
return( FALSE );
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1;
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
if (GetLastError() != ERROR_SUCCESS)
return FALSE;
if (!ExitWindowsEx(EWX_POWEROFF | EWX_FORCE, 0))
return FALSE;
return TRUE;
}
Then make a call to the function in you app..
MySystemShutdown();
I've tested it in windows NT and 2k.. havent tried it in 9x..

Hi, I have an CEdit control which can be resized. The user can switch from a single line edit control to a multi line control if he decides so.
How do I detect the number of lines? I need to catch the switch from a single- to multi line and change some atributes.
Thanks

GetLineCount() is a member of CEdit

ah no, GetLineCount() retreives the lines currently in the control, not the number of lines a edit control can hold.
you know, i need to detect if an edit control after WM_SIZE is big enough to hold multiple lines.

Hm... Is that even possible?

Try set a varible to the maximum count of lines and then every key press in the edit control you check if there is too many lines and then do something!?
Sorry but can't help you anymore!

UINT MyThreadProc( LPVOID pParam )
{
CMyDataStructure* pObject = (CMyDataStructure*)pParam;
// do something with 'pObject'
}
// inside a different function in the program
.
.
pNewObject = new CMyObject;
AfxBeginThread(MyThreadProc, pNewObjectPointer);
In my application, the main structure is simply a Dialog window. I placed the Dialog's pointer in the pObject and call the AfxBeginThread(MyThreadProc, pNewObject), however it always give me out run-time error when the Thread come to this line 'MyDialogPointer->UpdateData(false)'.
However if I replaced the line 'AfxBegnThread(MyThreadProc, pNewObject)' with MyThreadProc(pNewObjectPointer), no error come out.
Can anybody help me figure out what is the reason for it? And what should I do to sucessfully Perform UpdateData() of the Dialog by using Thread? ![Confused | :confused:](https://codeproject.global.ssl.fastly.net/script/Forums/Images/smiley_confused.gif)

That pointer should be allocated on the heap. Is your dialog staticly declared in the main thread?

Why?
He allocate memory in a function and then pass the address to that memory in AfxBeginThread (parameter to the thread func). In the thread function he create a new pointer (not on the heap) which will be assigned to the address that argument points to!?

The pointer arriving in the thread function is correct. But the structure it points to has a pointer member (probably a CDialog * ) which is not allocated on the heap! That one is the pain, and it doesn't appear in his posting.

Each thread has its own message map. As a result, you can't pass MFC objects that refer to windows between threads. The best you can do is pass the window handle between threads.

hello @all,
i have a mdi program. in the mainframe you have for example:
File -> Close
i would like to hide 'Close' to the users until the correct password entered.
enter password:
View -> Password
the 'Close' should not be gray or something like that. the user should not see that there is something like the 'Close', until he enter the right password.
i hope you can help me.
thank you very much

Off the top of my head, you could have a ON_COMMAND_UPDATE for the mdi child (which is where the
close command ends up) and use pCmdUI->SetText (m_bCanClose ? "Close" : "Password") to change the
text. You would also need a command handler to change the behaviour between password entry and the
normal closing.
For a "proper" app, you should load the menu strings from a resource rather than hardwired as above,
but you get the idea?
Iain.

Straight from MSDN:
If you implement a callback function, you will receive a handle to the dialog box. One use of this window handle is to modify the layout or contents of the dialog box. Because it is not resizable, modifying the old-style dialog box is relatively straightforward. Modifying the new-style dialog box is much more difficult, and not recommended. Not only does it have a different size and layout than the old style, but its dimensions and the positions of its controls change every time it is resized by the user.
