That's a mistake, you should do k = &i; .
If you need read-only access to the external parameter, use, something like the following code:
int i=9;
AfxBeginThread(Test, (LPVOID)i);
...
UINT Test(LPVOID pParam)
{
int iValue = (int) pParam;
}
On the other hand, if you need full access to the externa parameter, the code will be:
int i=9;
AfxBeginThread(Test, (LPVOID)&i);
...
UINT Test(LPVOID pParam)
{
int * piValue = (int*) pParam;
*piValue = 7;
}
Hope that helps.

NO.
Simply CString class overloads the (LPCTSTR) cast operator. See MSDN.

CString::Left returns a CString and CString overloads the operator LPCTSTR. See here[^]

Did you not read the documentation? CString::Left(int) will not return LPCTSTR value. What is that you exactly want to do?

No.

I think the question lies here:
"Be careful with this operator. If you change a CString object after you have obtained the character pointer, you may cause a reallocation of memory that invalidates the pointer."

I agree. But it's handy and hopefully prevents some guys to do things such
p=(char*)myString.GetBuffer(20); that may be even more dangerous.

Why deleting your question ?

He did not want to overload the server hard disk.

Maybe he has classmate on the codeproject that deletes his message

Hi all,
lets say i have this function in a ReadWrite.cpp file:
void CReadWriteDlg::OnButton4()
{
AfxMessageBox("test");
}
how do i call this function from a function in a different file altogether, say, SystemTray.cpp:
void CSystemTray::OnMyDeviceChange(WPARAM wParam, LPARAM lParam)
{
CReadWriteDlg::OnButton4(); //whats the correct syntax for this???
.
.
.
.
}
any help is greatly appreciated!
thanks!

Is this code helpfuls
CMain *m_Main=(CMain*)GetParent();
m_Main->Variable for function;

If you work with Dialogs then have CWnd and handles. So it is right to use PostMessage with user defined messages ( ->RegisterMessage ). PostMessage is better then SendMessage because it puts the message in the internal message queue. Read the fine MSDN.

I think it may be done by overriding CButton class then need to draw button yourself overriding DrawItem().

use SHFileOperation instead of RemoveDirectory. This function will delete the directory event if there are contents in that folder.

I like to Delete folder in any case even if other applications or other users are accessing the same folder. Forcefully i like to delete the Folder. I receive Error 32 when the function SHFileOperation(). Can any one tell me how can i acheive this.

yeah. if any process has kept any files opened from that folder. you will not be able to delete it.
