• Windows Forms Publishing in VS2005 is very slow

  Hi, I have simple Windows form project which I choose to publish. Usually it works fine but for my current project for whatever reason it'll sit for 3-5 minutes showing "publish building" while VS is doing nothing (no high CPU utilization, nothing) and then it'll finally publish.

• Windows Live Developer Forums Polygon Circle outside map boundries

  I am currently implementing the ve api in such a way that we are plotting points on a map and drawing a circle (polygon) around that point on a map based on a provided radius. The point in question is in the Fiji Islands which would be on the rightmost part of the map (approx. Lat: -16.694078, Lon: 179.835205). The radius of the circle is large and there are points which lie outside the map boundaries. The circle gets plotted correctly which would be on both sides of the map. However, there are lines between the top and the bottom of each circle part and the outside of the circle is shaded in. I can't include an image in the post, so i have included a link here (yahoo for lack of a better place to put them): http://new.photos.yahoo.com/dad ...Show All

• .NET Development Events with COM Interop & VB6.0 for C++

  Greetings, I appologize if this is in the wrong forum but this looks like the most applicable for my issue. I've written in VS 2005 C++ COM visible classes and these work great from VB 6.0 applications. My only problem surrounds events/callbacks. I've replaced a native ActiveX component with a .NET/COM visible one and everything works, except a simple event it needs. Under no circumstances have I been able to get VB 6.0 to reference a .NET class with the "WithEvents" keyword nor be able to install an event handler/callback. I need a very simplistic event or callback, which is a simple single-argument "TimeOut" handler for asynchronously processing data in the .NET assembly. It simply needs to call a given VB6.0 function ...Show All
