You can use managed DirectX. You have to download the the Dx9.0c SDK here http://www.microsoft.com/downloads/details.aspx?FamilyId=1C8DC451-2DBE-4ECC-8C57-C52EEA50C20A&displaylang=en[^]

Windows uses Win32-API. Dx was introduced as an API for games and multimedia-appz in the middle of the 1990s.

DirectX is included in windows since Windows98. In windowsXP sp2 DirectX 9.0c and .NET 1.1 framework (in the english version, but not in the german Roll eyes | :rolleyes:

) is included, so everyone should run your application.

Hi!
This may be a rookie question, but the truth is I can't do it: how do I use a C++ class in a C# project?
I have a C# project that works just fine, but I need to use a class implemented in a C++ project. I simply added the C++ project to my solution but I keep getting bulding errors. Is this the right thing to do?

Is your C++ class written in Managed C++? Only classes written in MC++ are accessible from C#.

Repeating an image instead of resizing it

Hello,

I'd like to know if its possible to repeat an image instead of streching it for a specified width/height (rectangle).

I tried to see if a DrawImage(...) method allowed me to do that, but to no result.

Thanks IA.

I'm working on a ASP.Net and C# project and want to send email through exchange server and
I only have a mailbox folder name (like "User 1") which exists on exchange server. If I send
email to "User 1" through my MS Outlook it works fine but I don't know how to obtain email
address of "User 1" from exchange server from my ASP.Net, C# application.

Can anyone post sample code or give some direction to resolve this issue.

Any help will be appreciated.

unmanaged dll problems/questions

22-Oct-05 5:52

Hi,

i need to work with an unmanaged dll and in each function i want to use i have a struct as parameter. The layout of this struct is given in a c header file, but i'm not sure how to get this working in c# Frown | :(

Here is apart of the struct:

<code>
struct _stEgControl
{                                
   struct _stEgData *pstEgData; 
   wchar_t *pszCommName;
   void    *pvEgVideoBufferAddress;
   void   *hEyegaze;
}
</code>

Question 1:
this struct inside my struct is rededined by me in a class with the same way. I'm not sure if this i right:

<br />
[MarshalAs(UnmanagedType.LPStruct)]<br />
public _stEgData *pstEgData;<br />

Question 2:
there is no wide character in c#. can i use a char?

Question 3:
how i have to work with this void* ? How do i manage this in my class ?
could it be in this way:

<br />
[MarshalAs(UnmanagedType.FunctionPtr)]<br />
public void *pvEgVideoBufferAddress;<br />

Thanks for help.
