Question

Get display adapter name using .Net framework

Asked by: A_Ridiculously_Long_Unique_Name

Hi Experts,

I need to get the video adapter name, *similar* to what is availabe using DXDiag

Eg: Name: NVIDIA GeForce 7300 GT
etc

However! I can not use DirectX SDK to obtain this data (due to project restrictions). Therefore, I need to get the equivalent information either directly from the registry (ugly) or via the Win32 API, or *ideally* using .Net Framework 2.0

Can you please provide a code sample C++ .Net preferred which demonstrates how to get the display adaptor name and some other attributes if possible, such as installed video memory etc.

Thanks

You can do this using WMI via Win32_VideoController. This example shows more then that, but it should get you started (and you can copy the code that you need): http://www.codeproject.com/KB/cs/EverythingInWmi03.aspx
