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);
}

...initialize your buffers with whatever content you need to...
char buffer90[40 + 50]; //I could have written 90 here instead of 40+50, it's just so for clearity's sake
strcpy(buffer90, buffer40);
strcap(buffer90, buffer50);
...both of your strings are in buffer90 now...

char first_buffer[whatever size_1];
char second_buffer[whatever size_2];

char *concatenated_buffer = new char[strlen(first_buffer) + strlen(second_buffer) + 1];
strcpy(concatenated_buffer, first_buffer);
strcat(concatenated_buffer, second_buffer);
...both of your strings are in concatenated_buffer now...
delete []concatenated_buffer;
