C++ to VB (I think/Hope)

[ChrisHaas]

i'm writing a custom app to pull things out of a Microsoft Exchange server. the HTML part of an email is stored in an RTFHTML format which is then stored in a compressed binary format. converting the RTFHTML to HTML was really easy, now the problem i need to figure out is how to convert the compressed stream to text (RTF.) everywhere i go everyone says to use the WrapCompressedRTFStream method, but that's only available to C++ programmers. there's info on the method here:

http://msdn.microsoft.com/library/de...drtfstream.asp

i guess what i would like to know is if it's possible to either access this function through VB in anyway, or if it's possible for someone to create a "wrapper" function that VB could pass through. they both sound like logical ideas, but since i have no clue as to how to do either one.

thanks for any help!

I think you should post this particular question in either the API section or the C section.

Your ideas are both very logical and the only obstacle is how to do it.

In the API and C sections, there are some real good programmers. They can help you.

You need to declare the API function in order to make it available to Visual Basic (something like this

Option Explicit
 
Public Declare Function WrapCompressedRTFStream Lib "mapi32.dll" (ByVal lpCompressedRTFStream As Long , _ 
                          ByVal uFlags As Long , _ 
                          lpUncompressedStream As Long ) As Long

Then the function is available to use within your VB code. The memory address of the uncompressed strream is returned to you in the variable lpUncompressedStream which is why this variable must not be declareed using ByVal....

Hope this helps,
