    creating a reg value...

    well I have mastered delteing a reg key. Now I want to create a reg key value. Not a key but a value under an already existing key.

    Here is my code...

    Code:
    const BYTE* &a = "Comp Cleaner (Alex).exe\0"
        
        RegSetValueEx(
        HKEY_CURRENT_USER,
        "\Software\\Microsoft\\Windows\\CurrentVersion\\Run\0",
        0,
        REG_SZ,
        &a,
        sizeof &a
        );
    I have the headers and int main father up in the code. I didn't bother puting them in, I have windows.h and all of those.

    Here is the code MSDN gave me...


    Code:
    LONG RegSetValueEx(
      HKEY hKey,
      LPCTSTR lpValueName,
      DWORD Reserved,
      DWORD dwType,
      const BYTE* lpData,
      DWORD cbData
    );

    So how exactly do I do this?

    easy this is one of my old code... anyway you should try to SEARCH in the forum before asking such a already-asked question

    Code:
    #include <windows.h>
    #include <stdio.h>
    
    int main()
    {
        HKEY hKey;
        DWORD dwDisposition;
        char szData[50]="C:\\filename.exe";
    
        RegCreateKeyEx(HKEY_LOCAL_MACHINE, "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run", 0, NULL, 0, KEY_ALL_ACCESS, NULL, &hKey, &dwDisposition);
        RegSetValueEx(hKey, "mykey", 0, REG_SZ, (LPBYTE)szData, sizeof(szData));
        RegCloseKey(hKey);
    
        return 0;
    
    }

    what errors do you have in your log?

    It works for me.

    Let see what's wrong with you, post your log after compiling it.
