How to detect if a DWG file is already opened by another user using C++?

—

You can check if a DWG file is already opened or not, using a file mode for "append." For example, the following code demonstrates the usage:

ACHAR fileName[] = L"myDrawing.dwg";

void fileInUse()

{

ofstream fp(fileName, ios::app) ;

if(!fp) {

acutPrintf(L"%s is IN USE.\n", fileName);

}

else {

acutPrintf(L"%s is NOT in use.\n", fileName);

fp.close();

}
