• Windows Forms Is this possible in .NET?

  Is it possible to make this kind of toolbar in .NET. If so how Matt Yup. You can make something exactly like that just using a Windows Form. Just drag a toolstrip onto it, size it how you want, and wa la! If you want cool looking graphics, then you will have to look into skinning a windows form. ...Show All

• Architecture Creating Vendor - Database Independent Application

  Hi I want to create a vendor - database independent application, that is, I want to create a single application that may run on Oracle/SQL Server/My SQL etc. First step towards this is to use ANSI SQL. But then arises questions like how to manage primary keys (have to mantain identity myself), how to fetch large dataset quickly (can't use SQL Server specific stored procedure), and other pertinent questions. Can anyone guide me, how should I pursue this goal, any ideas/suggestions, samples etc. Thanks. Regards, Ali I've done this a couple times and the right answer usually depends on how important performance is. For the most part, if you use ODBC and a common subset of SQL, you can run the same code on multiple databases but I've nev ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. IDisposable Interface

  Hi, In my old MDX game, I always use the IDisposable interface in every class and call the Dispose function when the object is not in use. It is because it seems that the garbage collector will not clean up the resource when I really need free space. But now for the XNA, is it necessary to do the same thing i.e, override the Dispose function and Dispose textures used in the class. Thanks Unless you want to micro-manage all your resources or if you are manually loading any resources (Texture2D.FromFile, etc), you don't need to implement IDisposable. contentManager.Unload() will dispose of all relevant resources created with it automatically. ...Show All

• Windows Forms Form Inheritance and Inheritance Picker problem

  Hi everyone: I have some base forms and usercontrols in a project named "UILibrary". And I create derived forms and derived usercontrols in other several projects. Everything goes very well. After a period of time, the solution grows and I modified classes in "UILibrary" and built it several times. The problem is coming. When I wnat to add a new item, also select Inherited Form or Inherited Usercontrol template, an "Assembly Load Error" message box shows. The message is "Unable to load assembly 'D:\Ap\UILibrary\obj\Debug\UILibrary.dll'. Ensure that the file is a valid .Net Framework assembly."  Then the Inheritance Picker&n ...Show All

• Visual Studio 2008 (Pre-release) Why a GeometryModel3D which Opacity setted as 0 can blot out other GeometryModel3Ds ?

  When I Set a GeometryModel3D object's Opacity to 0 in a viewport3D, it has been lucency,but it blot out other Model3D objects ! I think when I set a Opacity of GeometryModel3D object to 0,the GeometryModel3D object should be disappear ,and not hidden other Model .Anybody can tell me why You may just need to re-order the models you have in the scene so they render from furthest away from the camera to nearest to the camera. I don't know if this is true for Avalon but in DirectX, you have to render 3D things in the corect order for translucent surfaces to work as expected. Say you have the following scene: ------------ <- triangle A z=-1 ------------ <- translucent triangle B z=0 \/ <- camera z=1 If you re ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. C# and Dx9 trouble.

  Hi,  I'm not sure if this belongs in here, because I don't know wether my problem is a C# or a Dx9 issue, but ill take my shot. I made a C# Project using VS2005 Proffessional, which includes a Picturebox, in which I render my 3D stuff using DX9c. The app also has some non DX9 standard tools, like Buttons, Textfields, etc... . The second i start rendering with the Directx device, all non DX9 stuff stops being redrawn. The Buttons still work but theres no animation, no update, the Framerate stops being updated, nothing works which includes graphical altering except the DX9 stuff rendered within the Picturebox. I tried to Refresh the Form, but nothing helps, I'd appreciate all comments, thnx.

• Visual Studio Column Charts and other Report Viewer Controls

  I created a VB.net application whose main purpose is to produce reports to give to my students at a language school. These reports are meant to show how they stand against the class average. I initially I used excel, but there are limitations there that VB.net does not have. However, I have run into a wall when it comes to producing Charts. Therefore, can I do the following with Charts in VB.Net (VS2005) (LocalMode) with the ReportViewer control: 1) Create a combo line/column graph I want to have the class average in sectors (ie, fluency, vocabulary, expressions) and the line being their actual score. And can these be overlayed like in Excel. 2) The datafields and series confuse the heck out of me. My logic tells ...Show All

• Software Development for Windows Vista Latest DirectShow SDK, overview and samples

  DirectShow is one of the best things with Microsoft, BUT Im truly concerned about how the DirectShow developers are treated by Microsoft, there is no easy way of understanding how you can obtain the latest SDK and to receive a complete overview of the technology. I would like to see a separate complete DirectShow developer section where you can get a complete overview of SDK;s and what you need to develop "State of the Art" DirectShow applications. So please tell me im wrong and just did not find the right place to go and where I should go for that.
