Just want an executable to enumarate processes and enumarate loaded .dlls - winapi

Question

I want to make like a function with an argument stdvector::<std::string> of process names and std::vector<std::string> of .dll's to find in them and feed it into a function and get like PROCESSENTRY32 info std::vector<PROCESSENTRY32> returned of anything that matches the names.
You can google but won't find much as I have thanks for helping new to winapi but not to figuring things out

Answer 1

There is a perfect example to do exactly what you want on MSDN here. The relevant code is copied below. As the introduction to the sample says
To determine which processes have loaded a particular DLL, you must enumerate the modules for each process. The following sample code uses the EnumProcessModules function to enumerate the modules of current processes in the system.
Now the sample code
#include <windows.h>
#include <tchar.h>
#include <stdio.h>
#include <psapi.h>
// To ensure correct resolution of symbols, add Psapi.lib to TARGETLIBS
// and compile with -DPSAPI_VERSION=1
int PrintModules( DWORD processID )
{
HMODULE hMods[1024];
HANDLE hProcess;
DWORD cbNeeded;
unsigned int i;
// Print the process identifier.
printf( "\nProcess ID: %u\n", processID );
// Get a handle to the process.
hProcess = OpenProcess( PROCESS_QUERY_INFORMATION | PROCESS_VM_READ,
FALSE, processID );
if (NULL == hProcess)
return 1;
// Get a list of all the modules in this process.
if( EnumProcessModules(hProcess, hMods, sizeof(hMods), &cbNeeded))
{
for ( i = 0; i < (cbNeeded / sizeof(HMODULE)); i++ )
{
TCHAR szModName[MAX_PATH];
// Get the full path to the module's file.
if ( GetModuleFileNameEx( hProcess, hMods[i], szModName,
sizeof(szModName) / sizeof(TCHAR)))
{
// Print the module name and handle value.
_tprintf( TEXT("\t%s (0x%08X)\n"), szModName, hMods[i] );
}
}
}
// Release the handle to the process.
CloseHandle( hProcess );
return 0;
}
int main( void )
{
DWORD aProcesses[1024];
DWORD cbNeeded;
DWORD cProcesses;
unsigned int i;
// Get the list of process identifiers.
if ( !EnumProcesses( aProcesses, sizeof(aProcesses), &cbNeeded ) )
return 1;
// Calculate how many process identifiers were returned.
cProcesses = cbNeeded / sizeof(DWORD);
// Print the names of the modules for each process.
for ( i = 0; i < cProcesses; i++ )
{
PrintModules( aProcesses[i] );
}
return 0;
}
The only change you will need to make is to push-back the module names of interest to your std::vector<std::string> beforehand and then search that vector with the enumerated module names instead of printing them.
