I have a program written in VC6 (running on XP) that I want to stop from having multiple copies open. I want it to check whether there is another instance of itself running on start up and close if there is. Using FindWindow() doesnt work as it finds itself!
You can try creating a named mutex with CreateMutex() API and checking the result with GetLastError(). When the second instance of the app tries to create it, GetLastError() will return ERROR_ALREADY_EXISTS as the mutex is already created by the first instance.
I am making an application comprising both C/C++ and .Net environments (for different modules). Both C++ and .Net modules create logs in some XML files. But I am now facing many problems in maintaining all the log files (mostly because of their sizes).
I am planning to create my logs in some database. But I am not familiar with using any database with C++ or with .Net code. Here are my requirements:
1 The very first requirement is that database should be free to use.
2 database should be able to connect with both C++ module and .Net (C# module)
Can anybody suggest me any such database that can be used freely. Also help me in knowing some tutorial by which I can connect my application with that free database.
