Initialize the unmanged COM component in C#
-
Hello guys,
i am trying to use a COM library, which is written in VB, in my C# application. What i did are：
1. Add Reference: add the .dll file
2. Initialize the COM components with
[DllImport("ole32.dll")]
static extern int CoInitialize(IntPtr pvReserved);and then call 'int hr = CoInitialize((System.IntPtr)null);'
BUT, the return value of hr is always 1, that means the initialization is failure. WHO CAN HELP ME OUT OF THIS?
Thanks in advance.

Hi, normally you should not be required to initialize the library yourself. .NET creates a wrapper for you to handle the COM interaction.

Thank u for ur reply.
as u said, it is not necessary to initialize the COM library. My program can interoperate with the unmanged COM component without intialization.
