private void button1_Click(object sender, System.EventArgs e)
{
capture.FrameEvent2 += new Capture.HeFrame(CaptureDone);
capture.GrapImg();
}

error1 - 'DirectX.Capture.Capture' does not contain a definition for 'FrameEvent2' and no extension method 'FrameEvent2' accepting a first argument of type 'DirectX.Capture.Capture' could be found (are you missing a using directive or an assembly reference?)

error2-The type name 'HeFrame' does not exist in the type 'DirectX.Capture.Capture'

error 3- 'DirectX.Capture.Capture' does not contain a definition for 'GrapImg' and no extension method 'GrapImg' accepting a first argument of type 'DirectX.Capture.Capture' could be found (are you missing a using directive or an assembly reference?)

is it a callback from DLL so can you try this:

In project 1 or 2:

public delegate void MyDelegate(string delegatestatus);

public void somework(string p, MyDelegate mydelegatecallback)
{
callback("mystatus");
}

In project 3:

public void MyProjectcall(string delegatestatus)
{
// do your work here.
}

And when you call the method:

ProjectB.somework("parametervalue", MyProjectcall);
