1. LPSTR is a pointer to a multi-byte string (i.e. char *), but you are using wsprintf which is an unicode function (i.e. it works on wchar_t)
2. when used with wsprintf, the format string "%s" stand for an unicode string, but you are passing a multi-byte string instead: probably this is the reason of the crashes you are experiencing. Replace wsprintf with sprintf
3. to avoid problems with buffer overrun improved versions of sprintf and wsprintf are privided: think using printf_s and wsprintf_s

LPSTR lpszstr;

TCHAR str[100];
wsprintf(str,"%s","sdfsdfsd fsdfsdfsdf");

For example UpdateDriverforPlugAndDevice (), I used GetLastError (), see the error.

The problem is solved, but I now maintain two versions with the next 32, 64 a; do not know what a good way, just run a version.

I recently created a driver installation program, which uses a number of core functions such as UpdateDriverforPlugAndDevices(), using vs2008, in 32-bit operating system everything is working properly. But win32 program can run in x64, but under x64 it does not work. For example UpdateDriverForPlugandPlayDevices() raises an error, I used GetLastError (), and I see an error code. Later I was using a 64-bit system with vs2008 and compiled the x64 program, everything works fine, but the program can not run in win32. The problem is now solved, but I now maintain two versions of the installer 32 and 64; I do not know what a better way, I just run a seperate version of the executable.

int nColumnCount = m_myListCtrl.GetHeaderCtrl()->GetItemCount();

// Delete all of the columns.
for (int i=0; i < nColumnCount; i++)
{
   m_myListCtrl.DeleteColumn(0);
}
