• Windows Forms Change field-Values in Edit-Mode

  Hi, I try to implement "What-if"-scenarios in a gridview in its edit-mode - which means, one should edit a value in a column and instead of updating that one in the database I would like to adapt the other ones. E.g. column1 shows '1', column2 '2' and column3 the sum of these -> '3'. If the user changes the value in column1 to '3' and clicks 'Update', column3 should be adapted to the sum again -> '4'. My approach just to change a fields' value (to set the value to e.g. "100"): Protected Sub GridView_OutOfStock_RowUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewUpdateEventArgs) Handles GridView_OutOfStock.RowUpdating Dim  value As Int16 Dim row As GridViewRow = GridView_OutOfStock.Rows(e. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Glass-Reflection effect

  Hi, Im making a TicTacToe game with some friends of mine, just to get started on XNA. We are now beginning to be done with the gameplay, and now it could be great to do some effects, and boost the GFX a bit. So I whould really like the board to have surface that reflects the pieces, in a reflection, glass like way. Can anyone point be to a solution, sample code, or article or other way to do this Thanks in advance. Wouldnt it be more efficent to just render the scene from a different angle and use render targets to map this onto the reflective plane I don't know the specific syntax. But I believe it involved setting up a seperate camera which mirrors the players orientation through the refl ...Show All

• Visual C# 2005 Standard Edition compatible with C# Express Projects??

  I had C# Express Edition installed and thus have a bunch of projects that I did for school and work. I now have C# 2005 Standard Edition installed. When I try to run a project done in C# Express I get an error. Is this a known issue Thanks! David C# 2005 Standard Edition There is no such thing... do you mean Visual C# Standard Edition Or maybe Visual Studio 2005 Standard Edition The project files created by one version of Visual Studio 2005 (from Express on up to Team Suite) is exactly the same and can be ready equally by all. My guess is that you are trying to load a project from a later version of Visual Studio in an older IDE, something that doesn't work due to the project file format change. ...Show All

• Silverlight (formerly WPF/E) Where are the user interface controls? ie: Menu, TreeView, ListView, TextBox, ...

  I cannot see any user interface controls in the WPF/E reference. When I try to instantiate something as simple as a button, it throws an exception when loading the XAML. What is the status of the support of TabPanel, TreeView, Menu, Button, ListView, TextBox, RadioButton, ... Without these, I cannot see how it would be possible to build an application user interface with WPF/E. So how can we build a WPF-compatible TreeView control or a Menu control with these primitives How can we build a simple TextBox control I don't think it is feasible with the basic 'primatives'. To be even remotely useful, WPF/E has to have all the user interface controls that come with standard WPF. That also includes StackPanels, ...Show All

• Windows Forms Updating app.config

  I am trying to create a server installation (MSI) which during install populates the app.config with the user entered values and then updates and signs the manifests such that ClickOnce will be functional. I am not sure exactly of the method to update the manifests, or moreso if the way I am attempting is correct. here is some information about my setup here: I have the .deploy extension enabled; the msi configures the app.config with appropriate settings and sets the deploymentProvider codebase appropriately; once the config and application files are modified I have a batch file which executes the following mage.exe commands (actual filenames and paths obscured): mage.exe -Update <filename>.exe.manifest -FromDirectory <installed ...Show All

• .NET Development Executing Native Code From A Managed Thread

  Hi -- I'm about to reread the Geoff Schilling/Dave Stutz book -- which, now that I know what I need to learn from it, will be much more meaningful and useful to me than when I read it the first time, But before I do I thought I would ask one basic question that you guys might be able to inform me about. I'm wondering if it is possible and easy and done fairly routinely to call unmanaged code (that makes, for example, extensive use of Thread Local Variables) from within a managed thread without having to do a thread context switch in some way to an unmanaged thread Don't I remember that there is some kind of managed environment stack frame that allows you to do this And if so, does the managed environment place any significant limitat ...Show All
