    RegDeleteValue not deleting the value

    Hi all,

    I have a value in the registry of type REG_SZ in the key HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\ CurrentVersion\\Run

    The registry entry looks like this.

    Name: MyProg
    Type: REG_SZ
    Data: c:\MyProg.exe

    Now i want to delete this from the registry so ive used the commands

    Code:
    HKEY hKey
    
    RegOpenKeyEx( HKEY_LOCAL_MACHINE,TEXT("SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run"),0, KEY_ALL_ACCESS, &hKey);
    
    RegDeleteValue(hKey,"MyProg");
    RegCloseKey(hKey);
    Is there anything immediately obviously wrong with this?


    I also checked its Error_Success of the RegDeleteValue and it does not return ERROR_SUCCESS so it must not be deleting correctly.

    Thanks for any help

    Try calling GetLastError and looking up the error code.

    Do you have permissions to delete the key? are you logged into your computer with admin acccount rights?
