BUG: RegQueryInfoKey Returns Length Div 2 for cbMaxSubKeyLen (193465)

MORE INFORMATION

Steps to Reproduce Behavior

Before reproducing this problem, you must make sure that the Remote Administration Services is installed on both Windows 95 or Windows 98 computers. Verify that Microsoft Remote Registry is installed by selecting Network from the Control Panel and scrolling through the list of installed components. For additional information, please see the following article in the Microsoft Knowledge Base: Compile and run the following program from a command prompt on a Windows 95 or Windows 98 computer and pass a parameter identifying another Windows 95 or Windows 98 computer. The reported length of the longest subkey will be half the actual length of that subkey.

Sample Code

   #include <windows.h>
   #include <stdio.h>

   void main( int argc, char* argv[] ) {

       if (argc < 2) {
           printf("Usage: RegConnectRegistry \\\\server");
       } else {

           HKEY hRemoteKey = NULL;
           HKEY hKey = NULL;

           LONG lResult = RegConnectRegistryA( argv[1], HKEY_LOCAL_MACHINE,
               &hRemoteKey);

           if (lResult == ERROR_SUCCESS) {

               printf( "Connected to remote %s registry.\n", argv[1] );

               lResult = RegOpenKeyEx( hRemoteKey, "SOFTWARE", 0,
                   KEY_ALL_ACCESS, &hKey);

               if (lResult == ERROR_SUCCESS) {

                   DWORD cbMaxSubKeyLen;

                   printf( "Key opened.\n" );

                   lResult = RegQueryInfoKey( hKey, NULL, NULL, NULL,
                      NULL, &cbMaxSubKeyLen, NULL, NULL, NULL, NULL, NULL,
                      NULL );

                   if (lResult == ERROR_SUCCESS) {
                       printf( "The max subkey length of %s is %d.\n",
                          "HKEY_LOCAL_MACHINE\\SOFTWARE", cbMaxSubKeyLen );
                   }

                   RegCloseKey( hKey );

               } else {
                   printf( "RegOpenKey() failed.\nError: %d\n", lResult );
               }

               RegCloseKey( hRemoteKey );

           } else {
               printf( "RegConnectRegistry( %s ) failed.\nError: %d\n",
                  argv[1], lResult );
           }
       }
   }
