I am creating a dll and I have a problem with comparing char. I'm very new to c++ and I am frustrated with my problem:

PHP Code:

unsigned long CGamer::GetProcessPathByName(char *PathName)
{
    PROCESSENTRY32 pe;
    HANDLE thSnapshot;
    BOOL retval, ProcFound = false;
    pe.th32ProcessID = 0;

    thSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

    if(thSnapshot == INVALID_HANDLE_VALUE)
    {
        return 0;
    }

    pe.dwSize = sizeof(PROCESSENTRY32);

    retval = Process32First(thSnapshot, &pe);

    while(retval)
    {
        char nameProc[MAX_PATH];

        HANDLE h = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pe.th32ProcessID);

        // Check
        GetProcessImageFileName(h, (LPWSTR)nameProc, sizeof(nameProc)/sizeof(*nameProc));

        // Comparation
        if ( PathName is in nameProc )
                      ...

        retval    = Process32Next(thSnapshot,&pe);
        pe.dwSize = sizeof(PROCESSENTRY32);
    }

    return 0;
} 


I simply can not know if the word Pathname is in nameProc. Sorry for the ridiculous question.

PHP Code:

char * pF = "Something", * pS = "Other Thing";
if( !strcmp( pF, pS ) ) { /* Equals */ }
else { /* ... */ } 


strcasecmp transforms all characters to lower case so R will be equal with r.

strcasecontain checks whether ccSubString is included in ccString.

PHP Code:

bool strcasecontain( const char *ccString, const char *ccSubString )
{
    const char *ccCopyOfString = ccString, *ccSecondCopyOfString = ccString, *ccCopyOfSubString = ccSubString, *ccSecondCopyOfSubString = ccSubString;

    while( *ccSecondCopyOfString )
    {
        if( tolower( *ccSecondCopyOfString ) == tolower( *ccCopyOfSubString ) )
        {
            ccSecondCopyOfString++;

            if( !*++ccCopyOfSubString )
                return true;
        }

        else
        {
            ccSecondCopyOfString = ++ccCopyOfString;

            ccCopyOfSubString = ccSecondCopyOfSubString;
        }
    }

    return false;
}

Wouldn't it just be easier to tolower the entirety of both strings, then run strstr on them?

damn i'm so noob, i cant get it!

PHP Code:

unsigned long CGame::GetProcessPathByName(char *PathName)
{
    PROCESSENTRY32 pe;
    HANDLE thSnapshot;
    BOOL retval, ProcFound = false;
    pe.th32ProcessID = 0;

    thSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

    if(thSnapshot == INVALID_HANDLE_VALUE)
    {
        return 0;
    }

    pe.dwSize = sizeof(PROCESSENTRY32);

    retval = Process32First(thSnapshot, &pe);

    while(retval)
    {
        // Get
        HANDLE h = OpenProcess(PROCESS_QUERY_INFORMATION | PROCESS_VM_READ, FALSE, pe.th32ProcessID);

        // Name Proc
        char nameProc[MAX_PATH];

        // Check
        GetProcessImageFileName(h, (LPWSTR)nameProc, MAX_PATH);

        if ( strcasecontain(nameProc, PathName) )
            MessageBox(0, (LPWSTR)nameProc, L"Found", MB_OK);

        // Next
        retval    = Process32Next(thSnapshot,&pe);
        pe.dwSize = sizeof(PROCESSENTRY32);
    }

    return 0;
}

bool strcasecontain( const char *ccString, const char *ccSubString )
{
    const char *ccCopyOfString = ccString, *ccSecondCopyOfString = ccString, *ccCopyOfSubString = ccSubString, *ccSecondCopyOfSubString = ccSubString;

    while( *ccSecondCopyOfString )
    {
        if( tolower( *ccSecondCopyOfString ) == tolower( *ccCopyOfSubString ) )
        {
            ccSecondCopyOfString++;

            if( !*++ccCopyOfSubString )
                return true;
        }

        else
        {
            ccSecondCopyOfString = ++ccCopyOfString;

            ccCopyOfSubString = ccSecondCopyOfSubString;
        }
    }

    return false;
}

Reverse the order of these functions in your file. Or add the prototype of strcasecontain.

Btw you must import tolower( ).

[claudiuhks]

PHP Code:

#include <ctype.h> /* tolower */

bool strcasecontain( const char *, const char * );

//
// Your code here
//

bool strcasecontain( const char * a, const char * b ) {
  // This function's code
}
