Hi,

I have GoToMyPC but it is not turning off the monitor of the host computer when it connects. Nobody at GoToMyPC has ever heard of this problem and it is not a graphics card driver issue.

Therefore,

I need to write a program that will detect if the following processes are running and then turn off the monitor if they are: g2audioh.exe, g2host.exe, g2mainh.exe, g2printh.exe

I would like the program to autorun at startup.

The following codeproject articles discuss turning on and off a monitor, and detecting running processes (Turn Monitors On and Off from a .NET Console Application[^]Detect if another process is running and bring it to the foreground[^]), but I can't get the code to load into visual studio properly (my inexperience with being the issue). I am more familiar with simple C++ programs written with the Bloodshed compiler.

All advice and input will be appreciated.

Thanks Alot,

Matt

Here is a nice little project that you can adapt to your needs:

Hm. The project looks nice! The code can be used to understand how it works and to create something else. My 5.

That process viewer is great but I am looking for some tips on building a much simpler program. One without a GUI, command prompt or anything that will interact with the user.

The program I am envisioning is similar to a virus in that it will simply run its processes in the background unseen.

Thanks,

Matt

Use EnumProcesses()[^] to get the ProcessId list of the currently running programs. (You should do this periodically, every 1, or 5 seconds or something like that if you want a resident program.) And of course you want to get some info about every process to decide if you have to take action or not. To get some info about a process you usually need a handle to the process (not the id). Use OpenProcess()[^] to obtain a handle to a process by its id. Then you can use for example GetModuleFilenameEx()[^] to find out the path of the executable that was used to create that process (pass in NULL as the hModule parameter). You may also want to check out stuff here: PSAPI[^]

And turning the monitor on/off is the same in C/C++ as in the article your found, here is a the article written in C: Turn on/off monitor[^]
