• .NET Development Multithreading question

  Hello, I have a small program with a form control and two threads. These two threads are identical with only difference is the first one reads the top part of the SQL table, while the other one reads bottom part. Both use the same DLL (that I include using imports statement) and instantiate the same class within their code areas. Now, I want these two threads to use dll and do the work simultaneously. But, they seem to take turns. (I have a counter on the form for both ). I see that when one starts, the other one stops. When the second starts, the first stops. How do I make both run at the same time. They use same table for reading and updating the DB. Thanks in advance, Noorul No they do not. Processes a ...Show All

• Visual Studio 2008 (Pre-release) Forcing refresh of a Window object

  Hi at all I want to ask, if it is possible to force a repaint on a wpf Window object With WinForms there is possible to call Refresh() on a Form object. Is there a similar method to do this on the Window object Thanks for answering. The way with the worker thread i've canceled because i want a solution with a just one thread. the reason is when i have a second thread in which the UI component will be (time consumed) created, the application will throw an exception because the second thread is not STA. That means i need a solution with just one thread. But the when creation of the UI component is in the main thread (UI thread) it blocks during the creation time of the UI component the repainting of the first UI component. I've trie ...Show All

• Visual Studio Team System Permissions Problems!

  I have huge problems with the permissions for TFS. I have created a project in which I add an AD group (Projekt) to the Contributers group. My problem is that the members of the the AD group aren't allowed to add work items to the project. I have tried to add the group directly to the security system, added a single member to Contributors, add the AD group to the Area node and assigning permission, all to no avail. Please help!

• Game Technologies: DirectX, XNA, XACT, etc. Missing effect.Name and effect.Tag

  Hello I’m getting stucked in designing a ResourcenManager for XNA GS. Some basic thoughts : -          For bigger scenes it is not wise to load just models and manage them, because they hold   Effects and Textures. It would be a better idea to manage Effects and Textures separately, so that you can share them between ModelMeshes. In some cases it would be even better to share ModelMeshes too. -          To export a model, for example from a model tool to a x-file, you have to handle the material convertion problem (since the time of shaders). Maybe your model tool supports fx shader, but these are mostly not compatible with those in Game ...Show All

• Visual Basic [Console Application] Event when user logout/shutdown windows?

  Hi, I need my console application to execute a last command when a user logout or shutdown windows. Is there a way to catch those events or is there a specific event when windows try to close your application (you logout => windows want to close everything including your app). I found such thing for a windows form but not for a console application ... Thanks for your help. N. I've been looking at this and it doesn't seem possible. I tried getting various process info, but that doesn't work. And Jared's link specifically says: Important: Console applications do not raise the SessionEnding event. There doesn't seem to be a way to "see" a console app ...Show All

• Visual Studio Express Editions Combobox and Datagridview

  HI, I apologize if this has been covered. I'm sure there is a quick solution for this. I'm want to be able to take a selection from 2 comboboxes and display this data in a DataGridView. The Comboboxes are filled with data from a Database. Also I only want the GridView window to display data from the selection not everything in the table, so it would remain blank until a selection is made. One last thing, how do I stop duplicate data from being displayed in the comboboxes. Should I setup separate tables and make the tables relational Thanks in advance.

  If a certain user control has been shown during editing since the last time I compiled all labels disappear when I compile from that user control.

• Silverlight (formerly WPF/E) "Loading" Support

  Does anyone know of a good location for an example of how to add a "Loading..." sort of support to WPF/E My assuption is that some small XAML is loaded to do the "Loading" screen, then another XAML object is loaded via AJAX or XmlRequest to do the loading of a larger amount of XAML or code. Ideas WPF/E Pad does this. It shows the main UI which is fairly small from a download perspective and then use XMLHTTP to download additional XAML. A textblock updates the user of which files is being downloaded and is hidden after the last file has been downloaded See it here . Source is here . ...Show All
