How can I find the number of video frames set through a WMI call?

Does anyone know how to get Video Ram of PC from WMI call?

I've seen calls to the AdapterRAM property of the Win32_VideoController control object, but this only gives system memory and is not at all representative of video memory.

It turns out it was the adapter's RAM, and through an unfortunate match, the wrong conversion was used and given the system RAM ... on two different systems. Thanks for making us watch again.

For what it's worth, in a C # WinForms application:



int _ram = 0;

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select AdapterRAM from Win32_VideoController");

foreach (ManagementObject mo in searcher.Get())
{
   var ram = mo.Properties["AdapterRAM"].Value as UInt32?;

   if (ram.HasValue)
   {
      _ram = ((int)ram/1048576);
   }
}

From Microsoft Script Center Script under Hardware, then Video and Display, then Video Controller List Properties.

I would suggest that you might have to work something out between AdapterRAM and "VideoMemoryType"

We've already gone down the path of the AdapterRAM property, but that only gave us system memory, which has nothing to do with Video Ram. Is there any other way to get video memory?
