coinitialize (ole32)
 
.
Summary
Initializes the COM library on the current thread and identifies the concurrency model as single-thread apartment (STA).

C# Signature:

[DllImport("ole32.dll")]
static extern int CoInitialize(IntPtr pvReserved);

VB.NET Signature:

<DllImport("ole32.dll")> _

Shared Function CoInitialize(pvReserved As IntPtr) As Integer

End Function

User-Defined Types:

None.

Notes:

Besides the fact that CoInitializeEx has replaced CoInitialize, you shouldn't need to call this in managed code via PInvoke because the CLR already initializes COM when appropriate.
