• Visual Studio Team System is there any where, where i can get how to create report videos?

  Hi everyone, i am currently trying to create a report using 'type' Microsoft sql server. i have a due date to create a working report but i do not have the time to actually sit down and play around with it and see what works and what doesnt, and a demo video would be very very helpfull Thanks There is a video here http://teamsystemrocks.com/files/10/team_foundation_server/entry164.aspx showing how to create a custom report. You will have to modify the steps they take a little. I posted the steps below in your other thread - if you don't want to use the built-in data sources change their names and put them in the same folder as the report (or whereever else is appropriate).

• Software Development for Windows Vista would my application fail on xp and older os if I use the new vista platform sdk?

  Hi, For example, I would like to something like if(osMajorVer = 6) { ChangeWindowMessageFilter(); } else { do nothing; } and compile/link it using vista platform sdk. would the app built in this way break in older version of OS Thank you very much in advance. The app will work fine provided that you don't statically link to any new Vista specific API's. If you want to use Vista API's selectively by checking the OS Major version then you must load the API interfaces at runtime through LoadLibrary and GetProcAddress. For COM objects there's no problem, the object will simply fail to create if it doesn't exist. -- http://www.chrisnet.net/code.htm http://www.avdevforum.com/AV/viewforum.php f=7 ...Show All

• Windows Forms ListViewItemSelectionChangedEventArgs problem

  Hi, Having an annoying problem with a multiselect ListView control. Suppose I have five items in the ListView. The items can be independent of each other or connected to each other. For example item 1 and 2 are connected and item 3,4 and 5 are independent. If items are connected, then all the connected items shall be selected when clicking on one of them. In this case, when clicking on item 1 then also item 2 shall be selected. When implementing this I listen to the event ListViewItemSelectionChangedEventArgs. Of course I know that the ListView control fires events of all the selection manipulatings but I can't get the implementation right. This is what I do when user clicks on item 1: My event listener method is called and I see tha ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How to draw to an offscreen texture (for screen effects and video feedback)

  I'd like to do some screen effects with a pixel shader and maybe also some video feedback stuff. I'm trying to figure out how to render to a texture (maybe an Offscreen Surface ) which I'll then be able to render back on to the graphics device's buffer. I'm not sure whether I should use GraphicsDevice.CreateOffscreenPlainSurface or GraphicsDevice.CreateRenderTarget or what sort of paramters I should feed to either of those. The once I've got a Surface created by one of those methods, I'm not sure how to set it as a render target... GraphicsDevice.GetRenderTarget with an index above 0 always throws an exception, so I'm guessing there is some way to explicitly add Surfaces to GraphicsDevices as a render target that I can't seem to figure out ...Show All

• Windows Forms How do you use UseWaitCursor = true ?

  Hi, Idiots guide required. Just how is that UseWaitCursor property supposed to work - or rather, why does it appear to do nothing I have a button click handler, it sets "this.UseWaitCursor" to true, and goes and instanciates a DLL hosted dialogue form with a biggo constructor. It takes a while. Nothing happens to the mouse pointer, which is still an arrow. I changed my code to use "this.Cursor = Cursors.WaitCursor" (like we always used to do guys !) and it's markedly better. I searched the net and this question appears in a number of places, with various plausible (but non-working) solutions, but there must be a reason why this doesn't appear to be as simple as it looks. Yes I did try Application.DoEvents (which, persona ...Show All

• Visual Studio Team System Importing Work Items into Microsoft Project - changes dates

  When I import work items into Microsoft Project and the work items already have start and finish dates, Project always changes the start date to be the Project start date. Is there a way around this. It makes it so I can never easily create another project plan with correct dates because Project always 'baselines' all the dates of all imported work items. TIA Hello This could happen if in the TFS field mapping file, you have the date fields set to PublishOnly. Meaning, dates specified in Project are published to TFS, but the date information in TFS is not pulled into Project. One option is to change this to Publish and Refresh. http://msdn2.microsoft.com/en-us/library/ms252493(VS.80).aspx Note that Project is a complex t ...Show All

• Visual Studio Moving VSS6 from one server to another - howto, plus bonus questions

  Hello, We are currently running VSS 6.0a on an old piece of hardware running WinNT. That server is going away. We have a newer server running Win2003 Std. that will host VSS moving forward. I need to migrate our existing VSS over to it. I am by no means a VSS expert - mostly just a user, but now with Admin rights (this got dumped on me). Also, our office is closing next year, so I really don't see the need to upgrade to the newest version of VSS and deal with users not understanding this or that on the interface, or getting upset about the GUI changes. We'd really just rather move the data off of NT and onto Win2003, and let the company decide later if they want to upgrade VSS versions or move to different source control software. ...Show All

• Windows Forms How to make my own resize behavior

  Hi there... I have a problem with a long path... First of all I wanted to make a skinned UI and I found out that I could do that with a Form of FormBorderStyle.None ... Then after putting some background images on that I got the problem that the redraw of the UI is lacking when the window gets resized... the whole frame is shaking... so I decided to write my own resize behavior of a form... I wanted to simulate a "Show window interior while dragging - off" behavior ... So I get myself the desktop device context and draw a dashed rectangle around my app while resizing it. The problem is that the drawing of the rectangle lefts some traces like the desktop does not redraw. So my question is: Is there a simplier way to simulate a &qu ...Show All
