[out, optional] Pointer to a buffer to receive the INF file name assigned to it at the time it was copied to the INF directory. The buffer, if specified, should typically be MAX_PATH in length. If the SP_COPY_NOOVERWRITE flag is specified and the SetupCopyOEMInf function fails with a return code of ERROR_FILE_EXISTS, this buffer will contain the name of the existing INF file. If the SP_COPY_OEMINF_CATALOG_ONLY flag is specified, this buffer will contain the destination INF filename if the INF file is already present in the INF directory. Otherwise, this buffer will be set to the empty string. This parameter can be NULL.

        public System.Runtime.InteropServices.ComTypes.FILETIME DriverDate;

.

If this function is called with a ReturnBuffer of NULL and a ReturnBufferSize of zero, the function puts the buffer size needed to hold the specified data into the variable pointed to by RequiredSize. If the function succeeds in this, the return value is a nonzero value. Otherwise, the return value is zero and extended error information can be obtained by calling GetLastError. You can call the function once to get the required buffer size, allocate the necessary memory, and then call the function a second time to retrieve the data. Using this technique, you can avoid errors due to an insufficient buffer size.

However not all of the enums are available (e.g. CSIDL_COMMON_DOCUMENTS missing on .NET 1.1) therefore this is needed sometimes.

by using the 3 clipboard API's below first it work every time and you don't have to

.

CopyCursor reference will fail at runtime, according to documentation it is a macro:

.

    SetCaretBlinkTime(300)

If you come across this error "System.Runtime.InteropServices.MarshalDirectiveException: Cannot marshal 'parameter #6': Invalid managed/unmanaged type combination (this value type must be paired with Struct).", you may want to use

.

        [System.Runtime.InteropServices.ComRegisterFunctionAttribute()]

.

        [System.Runtime.InteropServices.ComUnregisterFunctionAttribute()]

.

I sometimes get error 1407 ("Cannot find window class.") when trying to create the window (after a successful call to RegisterClass)
