• Windows Forms Typed DataSet connection

  I am making extensive use of the typed datasets -- .xst files in the App_Code directory -- I let the wizard generate the stored procedures and the fill, GetData, insert, update methods. Very handy. However, I'm wondering how the connections are made and closed. Can anybody give me a rundown of how these data sets work Thanks in advance, Tom If you click on the show all files button in the server explorer it will show the code for the tableadapters class if you want to look at it. Basically behind the scene it creates a dataadapter which will open and close the connection for you when you fill your dataset or update the database. ...Show All

• Visual Studio Express Editions capturing pixel color

  I have an image in a pictureBox. How can I "get" the R, G, and B values of EACH PIXEL (I know about looping..I need the instruction to actually "get" the values). thanks, xlthim 1. I need to cycle through EVERY pixel in the image, not move the mouse over the image. For now, I'll just run a for loop and store them in an array. What I'm trying to do is manipulate the R, G, and B of each pixel, then redraw after my corrections.   2. I tried to run your exe, and I need an SDK for IC Imaging Control.   If I can get past this part, I figure I could run the for loop and call your function.   tks   Found the IC Imaging stuf ...Show All

• Visual Studio Debugging VS2005 Dialog Box

  I want's to debug what happen when VS2005 "Add new item" dialog box is click and what function were called when we create any file VIA this dialog box. What Can I do. When you click the Add New Item menu, VS 2005 shows a dialog with the item templates installed, scanning ItemTemplates folders like: C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\ItemTemplates C:\Program FIles\Microsoft Visual Studio 8\SmartDevices\Projects\ItemTemplates etc. which are also cached, AFAIK. When you select an item template, a wizard is invoked which adds the file to your project, or at least this was so in VS.NET 2003. The wizard typically receives a ProjectItems collection as parameter and it calls the AddFromTemplate / ...Show All

• Visual Basic Iterating through a given component type in a VB form

  Hello all, I am looking for a way to iterate through a given component type in a VB form. For example, if I want to go through all the buttons found in a given form and change their text to "XYZ", is there perhaps a "For Each" technique to do that The alternative is an ugly hardcoding of the button names, in the above example, and changing their text one by one ... not what I want. Cheers all. N. Farr Don't catch the exception for something like this (if you know it's going to cause an error, resolve the problem in code: throwing an error is 'expensive'):         For Each ctl As Control In Me .Controls       ...Show All

  Good day everyone, Currently I have WSS V2.0 (unserviced pack) + WSP 2003 (unserviced pack) + MS Project Server 2003 (unserviced pack) on a single server. I'm considering upgrading WSS to ver. 3.0.

Mohamed Mohamed, Cant give you a great answer on the Project server bit as its been a few years since i dealt with that but for the other two.... Get the OS Updated first then proceed with the WSS SP. Once you complete that you should be in a decent place to start your upgrade to WSS 3.0. I hate to guess with ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Making XNA sing in 2D

  I'm new to managed code as far as using it for anything but tools and other applications where speed doesn't matter. I'm playing with XNA and looking to have some fun in 2D. I know this is the beta and all but the performance of using spriteBatch to draw sprites is really lacking. 5000 unlit, perfectly opaque square sprites using the same texture shouldn't run at 5 fps. 1000 sprites runs at just under 30fps, that's without any other game logic going on. Woof. I am looking to squeeze performance out of 2d mode, however I'm thinking that perhaps the best thing to do is just render in 3d mode and use large triangle lists to draw my sprites. Would that be the best course of action, or are there yet lots of tricks to rendering in ...Show All
