My fault! I will study the documentation now, thank you for the tips.

But can you give me a code example to PAUSE the callback, give control to the client-exe to show a messagebox-form to the user, and return the result to the callback so that it can go on relying upon the user answer? No. I won't do all the work for you... ;) It's not difficult. Just give it a try.....

The way you're doing it "processInfo" is not filled with correct values. So the appliaction calling CreateProcess will use a "processInfo" structure with either random values or maybe zeroed out values. That won't work well. Ok! Instead you should in your hook callback function ...

Thanks, this will be useful of course in future.

Now I know what was the cause of the problem: applications launched in asynchronous way work perfectly, applications synchronous not, because the callback does not wait for the CreateProcess to finish, so Windows reports an error (but there is actually no error) and the calling process does not wait...

If you find time... thank you so much!

Yes, please, I'd love to. Here it is . Screenshots here (Italian blog). AFAIK CreateProcess/CreateProcessEx is not enough. There are other CreateProcessXXX (CreateProcessAsUser i think) API's which do not desend down to CreateProcess/Ex therefore they will be missed by your hook. Also does you hook...

Yes, I saw that... But I'd like a fully functional example that compiles with no changes needed!

I usually don't ask this kind of things, as ready-to-use source-code, but this time I really need it, even the simplest one (that I will expand on my own).

I think we are mixing things up here and talking about too different things... I agree... :sorry: But I was answering the very first question of torstenv. If you have a system-wide hook which intercepts process creation then what are your issues? My system has a listing of processes that a user can...

Wich demo are you talking about?

All my CreateIPCQueue related code is in C++ - i can post if you want - just post back if you want me to.

I work in Delphi...

Has anyone found a reliable method to detect/hook ALL process creation in Vista? Yes, I have. My hook works with XP and with Vista. With Vista, mark your executable with a manifest file requesting Admin privileges (an admin password will be asked at executable launch). Now I ask you: have you found...

// In you control application 1) Define a unique IPC name 2) Define a critical section or other thread-protection mechanism 2) Create a callback routine - code is shown in both the help and the examples 3) Call CreateIpcQueue/Ex - you now have an IPC channel created, you have protected access to it...

With madshi.
Unfortunately this is not enough for me. I'm using Delphi, of course.

Thank you in advance for any help!

I can I do the same IPC call with my client in Delphi?
I have the same problem: make the request from the client to the user (from the dll it works, but I don't like it) making the CreateProcessCallback waiting for the client method to terminate.

Please help!

Please, I really need an IPC tutorial (in Delphi!) with code example to how implement IPC: my_hook_dll <--> my_exe_client

I'm stuck!!!
