• Visual Studio Tools for Office Debug deployed solution

  I can launch my deployed VSTO doc, then switch to my VS solution and debug-attached to the correct Word process and debug things. But how can I debug ThisDocument_Startup as there is nothing to attach to at this point I need to be able to fully step through a deployed Word VSTO solution. TIA Yes you can, I do this often. Just add a MessageBox as the first line in ThisDocument_Startup ... when your message box displays, go to attach to the process, find WINWORD.exe (should be only one of these), attach to it, set your break-point in your code, then click the 'OK' button on your message box ... assuming that you have set a valid break-point, VS should stop on it when it gets hit.

• Windows Forms Windows Form to access websites?

  I play a browser-based game. I'd like to make a windows form UI for it, mainly to improve navigation and a bit of automation. To do so I have to; 1) 'fake' http posts (as in submitting html forms) 2) be aware of response.redirects (I might tell it to load page1.aspx, but that in turn might load page2.aspx. I need to know which page is sent back to me). 3) 'fake' certain things like cookies, agent strings etc. Any clues on how to go about this Even a starting point for my research would be appreciated.
