 Posted: Sat Mar 14, 2009 2:14 am Post subject: OpenProcess + GetCommandLineW -> kernel32 API calls |
 |
|
I want to open a specific process via a kernel32.dll API call. to obtain some details, for example the process' PATH or the process' priority etc...
I receive "The parameter is incorrect" for the OpenProcess API call...
Please help me with the correct code... I tried many combinations...
Plus, after the correct API call of the OpenProcess function, please help me with the GetCommandLineW function, to get the command line argumments of the specific process...
| Code: |
loadlib kernel32.dll
#DEFINE FUNCTION,GETLASTERROR
rem For example, 1672 is the PID
%%PID =1672
%a =@binary(DWORD,%%PID)
rem PROCESS_QUERY_INFORMATION = $0400
%%openProcess =@LIB(kernel32,OpenProcess,INT:$0400,BOOL:,@addr("%a"))
%%tmp1 =@getlasterror(kernel32)
rem %%currProcess =@LIB(kernel32,CloseHandle,%%openProcess)
rem %%tmp1 =@getlasterror(kernel32)
freelib kernel32.dll
stop
:GetLastError
# The GetLastError will return the last-error code value
# Parameters:
# dllname
#
# Syntax: %A = @GetLastError(<dllname>)
%%tmp1 =@lib(KERNEL32,GetLastError,INT:)
# Test for the first parameter. If NULL use the KERNEL32.DLL
If %1
%%tmp2 =@lib(KERNEL32,GetModuleHandleA,INT:,STR:%1.dll)
Else
%%tmp2 =@lib(KERNEL32,GetModuleHandleA,INT:,STR:kernel32.dll)
End
%x =@fill(256,,Z)
%%tmp3 =@lib(KERNEL32,FormatMessageA,INT:,INT:$0800,%%tmp2,INT:%%tmp1,INT:0,@ADDR("%x"),INT:255,INT:0)
warn API call error: %%tmp1 "(0x"@hex(%%tmp1)")"@cr()@adjust(%x)
exit

I don't think that is going to get you what you want..
| Quote: |
The GetCommandLine function retrieves the command-line string for the current process.
LPTSTR GetCommandLine(void);
|
Meaning it will get the command-ling string for the process that calls the function(your app).
Unless that is what you are after, then you wouldn't need the OpenProcess and all that..

| Ok. I think you are right... So, how can I get the command line argumments of a specific process already started? |
