• Windows Forms DataTable sorting

  I have a DataTable binded with DataGridView. I may provide my own sorting for DataGridView (via ICompare), but I can`t when DataSource property is used (and it is in my project). I would like to sort rows, when user clicks in the header of a specific column, but I don`t want the default sorting. Default sorting is like that: 0,1,11,12,2,3,4I want a numeric sorting: 0, 1, 2, 3, 4, 11, 12how to achive this Seems correct, thank you very much, but the problem now is, that I have the first column of type int , and the rest of the columns of type A. Klass A has method ToString() overriden to meet my personal expectations, that in specific situations returns empty string ( "" ). I also set datatype for ...Show All

• Windows Forms Auto-Login using Web Browser Component

  Hey, I wonder if anyone knows how to create an app using C# and the Web Browser Component that detects both textfields for username and password, inputs the appropriate values within them and then simulates a Click in the Submit button... Thanks The main intention is basically to detect a textbox in a web page and fill it with a certain value of a string, it is only for educative purposes I wish to know how could C# interact with webpages for accessibility purposes, for example it is a lot easier to simply press a button and fill a login form than to fill the fields by yourself. Once again, the goal is to use a C# app (preferably using the Web Browser Component included in Visual C# Express 2005) that can detect a login f ...Show All

• SQL Server Checking to see if a record exists and if so update else insert

  I've decided to post this as a sticky given the frequency this question is asked. For those of you wishing to build a package that determines if a source row exists in the destination and if so update it else insert it, this link is for you. http://blogs.conchango.com/jamiethomson/archive/2006/09/12/SSIS_3A00_-Checking-if-a-row-exists-and-if-it-does_2C00_-has-it-changed.aspx Thanks Jamie!

• Visual FoxPro Import Command problem

  I downloaded some data from Yahoo and saved it in .scv MS Excel format. It is a MS Excel Comma Separated Values File . Now I want to use an IMPORT command to import the data in VFP. I run into a problem with it. The command I use is as follows: IMPORT FROM "D:\VFP_Projects\DATA\D_data\table1.csv" DATABASE "D:\VFP_Projects\DATA\D_Data\d_HistData.dbc" NAME tempTable TYPE XLS It seems the problem is related to the fact that this file extension (.scv) is not specified in the IMPORT command description. If I use TYPE XLS I get an error " Microsoft Excel file format is invalid ." If I put in TYPE SCV instead I get an error that there is a "syntax error." If I drop the TYPE clause altogether I get: &q ...Show All

• Visual C# Why is this not valid!!!???

  I have a question that nobody in my department is able to answer. It came to me while using the Class Designer to stub out our data access layer of our application. The question is: If I create an abstract worker class as such: public abstract class MyClass { public abstract void MyMethod( DataEntityAbstract Entity); } Then try the following in its derived class: public class ThisClass : MyClass { // ThieDataEntity is derived from DataEntityAbstract class public override void MyMethod( ThisDataEntity Entity) { // Do Something } } Visual Studio 2005 will throw a compilation error.

• Game Technologies: DirectX, XNA, XACT, etc. Rotating models around their own centers

  Hello, I'm having a bit of trouble rotating models around their own centers; instead any new physical object I place in the world will perform its rotations from the world origin, not their own. I understand that the order of the matrices matter, and as far as I know I'm applying these correctly. Each object is a DrawableGameComponent and has its own transform matrix. In the drawing code updates by the transform and world matrices: public override void Draw(GameTime gameTime) { foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.World = destinationBoneTransforms[mesh.ParentBone.Index] * world * transform; ...Show All

• Visual Studio Team System TF31002: Unable to connect to this Team Foundation Server.

  We just installed Team Foundation Server Suite. I can access it from the same machine but when I try from other machines, I get a failure notice, TF31002: Unable to connect to this Team Foundation Server. Possible reasons for failure are - The Team Foundation Server name, port or protocol - The Team Foundation server is offline - Password is expired or incorrect. For more information, contact the Team Foundation Server Administrator. Well, the server name, port and protocol are correct, the server is online and the password is not expired and I am the Administrator. Any hints We solved our problem too. I uninstalled and reinstalled Team Explorer and everything is fine now. I suspect that the de ...Show All

• Software Development for Windows Vista Problem with uncompressing files.

  Hi I use the Vista thats the latest from MSDN and running it on a brand new laptop. When i try to uncompress files in both .NET and the UI it runs the application but no files get unzipped to the file. The UI goes away and then nothing happens. I tried downloading Winzip and Winrar and they all behave the same. I wrote my own unzip code in VS 2005 using C# and the code executes fine, no errors. But still no files unzipped. The only way i can unzip files are to start winrar and select the path to where i want to send it. Right click method does not work at all. Thanks I posted a solution to this on my blog: http://bphillips76.spaces.live.com/ Bryan Phillips MCSD, MCDBA, MCSE blog: http://bphillips76.spa ...Show All

• Visual Studio Team System Scalable deployment using distributed designers

  Hi, I'm trying to create a deployment diagram that has an ASP.NETWebApplication deployed to multiple IISWebServers. I have set the Scalable property of the application, the server, and the zone the server belongs to, to True . However, I'm still unable to deploy to a 2nd server: 'Application has already been bound. Unbind the previous version, or configure another use of the application in the System Designer' What more is there to configure Thx in adv. Eric Short Answer: Yes you can do this, you'll need to create another instance of your ASP.NETWebApplicaiton on the system desginer first. Longer Answer: The issue is that the specific instance can only be bound once. On the AD y ...Show All

• Visual Studio Express Editions Cleaning up

  I have a class that contains a looping thread checking for input from a socket. When my application closes I would like this class to stop the thread so the program exits cleanly. I managed to stop it cleanly in my main program by listening for the game.disposed event, but i would like the class to close itself internally when the rest of the program is being cleaned up. Show me the way someone... Keep a reference to the thread instance and call the Abort() method to stop it when your application is closing. Another way would be to have a bool in the class where the thread code is running in declared as volatile. Default the value of the bool is false and when the application is closing it gets set to true. In the thread you check ...Show All
