• Visual Studio VSS Lan Service working randomly

  Hi, The Lan Booster service works randomly here. Sometimes everything is ok, and sometimes, for the very same operations, for the same database/project and on the same system, I get the following message: Unable to use SourceSafe LAN service, performance of SourceSafe operations will not be optimal. The service is running on the system hosting the database. Known problem I'm not very familiar with DFS, but I think that you're accessing the database with a "generic" path, something like \\domain\dfsroot\vss , isn't it If yes, VSS LAN service is not going to work. The client takes the databae path in the form \\server ...Show All

• Windows Forms Updating image of single listview item?

  Hi is there a way to update just a single item instead of the whole view Example: ... myListViewItem.ImageIndex=-1; myListViewImageList.Images[0]=new Bitmap("somepic.bmp"); myListViewItem.ImageIndex=0; //now do update the item ... The effect I would like to achieve would be the only redrawing of the updated item. You can simulate that by clicking on the updated item. Tthis causes to redraw only the selected item. Greetings, Sven. Instruct the ListView to invalidate just the area contained by your item. listView1.Invalidate(myListViewItem.Bounds); To force the update to t ...Show All

• Visual Studio How to support template export in VS 2005?

  Hi,    There is not the topic of the template export implementation In VSIP document .     Could anyone do me a favor   Thanks! You cannot disable the command. One note: we have tried export template with other languages, and it will work, but there are very stringent requirements. For example, you must implement VSLangProj on your project, including all the properties that VB, C#, and J# do. But this is unsupported, so there may be some bugs when working with other language types. Craig ...Show All

• Visual C# How good is the garbage collector?

  Just how good is it Is it a C# feature or .NET Framework feature Thanks Quite a bit of the .NET Framework simply wraps around existing Win32 or COM(+) functionality. WinForms is an excellent example, where you still have a HWND backing every window and control. GDI+ is another good example. Take a look at GdiPlus.dll, the Win32 DLL that implements the actual GDI+ functionality. (You can find P/Invoke signature for GdiPlus.dll at http://www.pinvoke.net/default.aspx/gdiplus.GdipAddPathArc  and related subsections.) You'll quickly see that System.Drawing is a thin wrapper around it. (GDI+ - and ...Show All

• Software Development for Windows Vista SQL Server 2005 and WF

  Hi. Is it possible to use WF in a managed function/stored procedure in SQL Server 2005 If one have a state machine for order it would be nice to use the same state machine in the webshops and in the stored procedures. Interesting question, never tried that... as you can use C# in the stored procedures now, it should not be a problem to write one that starts a WorklfowRuntime and executes a workflow. The only problem I would see is, that there is only one WorkflowRuntime allowed per application domain and I guess that all stored procedures will be executed in the same one. ...Show All
