Question

I’ve got most of the code for writing a value to the windows registry, however when I change the path to a dummy key and value that I’ve set up for testing it fails. My code is below:

    HKEY hKey;     LPCTSTR sk = TEXT('SOFTWARE\TestSoftware');      LONG openRes = RegOpenKeyEx(HKEY_LOCAL_MACHINE, sk, 0, KEY_ALL_ACCESS , &hKey);      if (openRes==ERROR_SUCCESS) {         printf('Success opening key.');     } else {         printf('Error opening key.');     }      LPCTSTR value = TEXT('TestSoftwareKey');     LPCTSTR data = 'TestData\0';      LONG setRes = RegSetValueEx (hKey, value, 0, REG_SZ, (LPBYTE)data, strlen(data)+1);      if (setRes == ERROR_SUCCESS) {         printf('Success writing to Registry.');     } else {         printf('Error writing to Registry.');     }      LONG closeOut = RegCloseKey(hKey);      if (closeOut == ERROR_SUCCESS) {         printf('Success closing key.');     } else {         printf('Error closing key.');     } 

All three tests yield error statuses.

The part that confuses me is that I was able to run this code when pointing it at other portions of the registry. Any ideas?

thanks, brian

I feel silly. The solution is that need to properly escape the slash in the string as follows:

LPCTSTR sk = TEXT('SOFTWARE\\TestSoftware'); 

Hopefully someone finds this useful…
