Detecting a Windows process from within PB35

[Jean Baque]

Hallo,

Is there a possibility to detect from within a little tool done with PB35 if a real program for Windows is always running or not ? I am using this tool on win9x and winXP.

Is there a possibility to call a dll which can do the job ? I have never called a windows dll !

Because of the time difference, I won't read your possible replies before several hours.

Thank you very much !

AFAIK there is no way a DOS program can call functions in a DLL.

However....
You can create a Windows' program to list all running processes.
From MS-DOS you can SHELL a Windows Program.
Ergo, your DOS program can get a list of running processes.

Thank you, Michael !

Since I am not capable of doing such a Windows Program, I continue using with the SHELL a little tool named "PV.EXE". It does the job !

Whoo-ee. A 'debug' script. Don't hardly see those anymore!

I know I have seen code that you can call an interrupt to see whether or not your ap is running under windows. I can't find it here at the moment, but if I do, I'll post it.

I suppose I should have mentioned...

Assuming that script generates a COM file which will execute correctly from MS-DOS, it can be included in your PB/MS-DOS program and executed from code.

It 'should' work by using inline assembly language wrapped in a SUB or FUNCTION and called normally. There might be some minor tweaking required, and I think a working knowledge of assembly language will be useful; but I have to believe this is very much in the realm of the do-able.

OR,

Find a friend with a Windows' compiler, and start here...

That can generate a list of all running processes, and you can find the names of the modules (EXE and DLL files) linked to that process.

Write the results out to a disk file; SHELL this program from your DOS program, and read the disk file when it's done.

Hi,
You can call a 32-bit DLL from DOS using a DOS Extender.

I'm presently using the HX DOS Extender under MS-DOS 6.22.

You can make the calls from PB3.5, but it is a very messy process, which involves using LoadLibrary, GetProcAddress, FreeLibrary, etc. Mind you, these have to be translated into Interrupt Calls. For example, Int 21h, AX=4B00h (LoadModule/LoadLibrary) is what you would call to load a DLL from PB3.5.

Again, you require the HX DOS Extender in order for the Interrupt calls to work.

I find it much easier just to create the programs using PB/CC 5.02, and just run the resulting .EXE from DOS that has the HX DOS Extender installed.
