    reg edit

    is there a way to make a program that edits the registry on a computer provided that the value to edit is already there. Also have it that the value to change it to is already preset in the program so all you have to do is open it and it runs edits then closes itself with out needing to give the program any input at run time?

    srry if you have a hard time reading or understanding

    Yes.
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    X^2, I agree with every point you made completely.

    So, newbie, you're saying you want to write a program that does nothing when it runs except edit an existing registry key and then exit.. Is that right? I have a program that does just that... Let me go find it...

    Ok, here's a snippet:
    Code:
    //---------------------cut here----------------------------
        // now make the change in the registry
        if (*valueName != 0 && *valueData != 0) {
          processedSomething = true;
    
          const char *keyPath = *key != 0 ? key : subKey;
    
          // if our key path has changed...
          if (keyChanged) {
            keyChanged = false;
    
            // close the previously opened key...
            if (hKey != NULL) {        
              RegCloseKey(hKey);
              hKey = NULL;
            }
    
            // then open our new path
            if (RegOpenKeyEx(baseKey, keyPath, 0, KEY_ALL_ACCESS, &hKey) != ERROR_SUCCESS) {
              logout << "* ERROR * - Unable to open registry key: \"" << baseKeyName << "\\" << keyPath << "\"" << endl;
              hKey = NULL;
            }
            else
              logout << "SUCCESS - Opened registry key: \"" << baseKeyName << "\\" << keyPath << "\"" << endl;
          }
    
          // if we have a key open
          if (hKey != NULL) {
            if (RegQueryValueEx(hKey, valueName, 0, NULL, NULL, NULL) != ERROR_SUCCESS)
              logout << "* ERROR * - Unable to query value: \"" << keyPath << "\\" << valueName << "\"" << endl;
            else {
              logout << "SUCCESS - Queried value: \"" << keyPath << "\\" << valueName << "\"" << endl;
                
              if (RegSetValueEx(hKey, valueName, 0, REG_SZ, valueData, strlen(valueData) + 1) != ERROR_SUCCESS)
                logout << "* ERROR * - Unable to set value: \"" << keyPath << "\\" << valueName << "\"=\"" << valueData << "\"" << endl;
              else
                logout << "SUCCESS - Set value: \"" << keyPath << "\\" << valueName << "\"=\"" << valueData << "\"" << endl;
            }        
          }
    
          // reset the value info
          *valueName = *valueData = 0;
        }
      }
    
      // close the handle to the registry key 
      if (hKey != NULL) {        
        RegCloseKey(hKey);
        hKey = NULL;
      }
    //---------------------cut here----------------------------
