• Visual Studio 2008 (Pre-release) Exception when running on x64 Vista, possibly in system theme?

  A user of my application is running the newest public beta of Vista x64 (build 5384) on an Athlon64 3200+, and is consistently experiencing an exception that 32-bit Vista and WinXP users aren't seeing at all. My debugging ability in this case is limited because I do not have a x64 machine running Vista, so I'm unable to pinpoint exactly when this is occuring, but from discussion with the user I believe it is happening when a Button is changing from IsEnabled = true to false. http://graalbin.londeroth.org/235 -- that is the exception that's occuring and its stack trace. Judging from the last few stack frames, it's happening when a button is ...Show All

• Visual C# display a form at selected mouse coordinates

  Objective: (This is not an MDI application) Display a child form containing a datagridview that contains the child records of the selected row in a datagridview. Have this display on a parent form right below the selected row in the datagridview. Problem: I am unable to get the correct location of the cursor on the parent datagridview control passed to the child form so the child form displays correctly. I am passing the location to the constructor of the child form so that I can call this child form as you would call ContextMenu.Show(DataGridView, e.X, e.Y) but I am not sure how the Point gets set to the Control and not the ...Show All

• Visual Studio Team System Expand project properties...

  Is it possible to expand the project properties For example when adding a project i would like to add the impact for the "customer", "customer(forn), and "dealer", or the estimated duration. I solved this by adding a work item "project information" and linking all tasks to this information... whitch doesn't work that well. I think I'm a little lost. The project tree is for project isn't it, and the work items are tasks, bugs, etc. We work whith smal projects (2 month's and 30 tasks). To have project metadata at hand when viewing a work item (by expanding the work item), would result in entering the ...Show All

• Visual C++ Printed text is overlapping!

  In document Image Writer, text looks just OK, and ofcourse it is as I was tuning it according to image writer. But when I print that same stuff on the paper, text is overlapping!! I am using pInfo->m_rectDraw.Width() and Height() to retreive width and height in points. In Image Writer exactly 5 paragraphs fits the paper and on regular printer letters are about 5 times larger and only about 2 paragraphs can be printed on 1 paper. Also, in Print Preview, letters overlap BADLY and while printing they overlap much less but are too large anyway. Only image writer retains good proportions... Graphics are OK all the time, just letters are giving ...Show All

• Visual C++ console from form

  Hi! How can I call a Console window from a form application Ok: I dug a little deeper and I think I know what is going on here. The problem is that by-default a Windows Form application does not have a console associated with it: so any calls to Console::WriteLine will send the output into a black hole (\dev\null). The case where the application will work is if you start it from a console window because in this case the application will have this console associated with it and so calls to Console::WriteLine will have some where to send the output. In order to ensure that an Windows Form application always has a console to write to you ...Show All
