• KRISTER How do you add EndCap AnchorCircle to each line in a Path

  Hello, I'm using GDI+ to create a graph. I can have about 20,000 points and want to make a curve out of this points. I iterated each point and used DrawLine to draw each line and it was really slow. I found that with: graphPath.AddLines(test) 'test is an array of points grfx.DrawPath(pluma, graphPath) I can make ir really fast... but the thing is that the pen I'm using only displays the EndCap for the whole path (only at the end) and not for each of the lines that create that path. I want to show where each point is located with pluma.EndCap = RoundAnchor...it worked well with DrawLine... but with the path I get the EndCap only at the end of the path... I used AddEllipse for each point but it's very very slow. ...Show All

It often happens that I click exit button by mistake, which is especially annyoing when I work on l ...Show All

• Grant_A Embedding Video in a Visual Basic Web Browser

  Pardon me for posting twice in quick succession, but I've always found that if I post two questions in a thread only one gets any attention. I'd like to embed video into the current application I'm designing in Visual Basic 2005. The only way I could think to do this was to have a WebBrowser control and insert the necessary text for embedding a video player into the DocumentText, but that didn't seem to work. What's the best way to do this The video formats will be restricted to .avi and .asf. For reference, here's the way I tried to do it; this code is called whenever the 'VideoURL' is changed.
