• .NET Development How to remove columns from DataView but not from DataSet table

  Hi, I use DataSet only one times and then I create DataView many times in the cycle . This DataView is used for generating individual client offers.

• Visual C++ Underlying CRT variable messed up by third party lib

• Windows Forms change content/using tabs

  This is an example of what I'm trying to do. So first you have the first (click for image)situation. Then you click "Update" and you get second (click for image) situation. My question is How Thanks Generally speaking, you change the right part according to the left part. To do this, you may use splitcontainer control to split the windows form into two part. And the left part in the image is very similiar to the outlook bar, if you want the same effect, you can have a search and i'm afraid there are lots of demos out theres. As long as you click the button, say 'Update', the right part is updated, changed to a new interface. Just give you a gerneal idea. Hope this helps. ...Show All

• Visual Studio 2008 (Pre-release) XAML code and C# code kept in sync

  WPF is obviously a step in the right direction in enabling developers to make modern UIs, however Windows Forms still has quite a few advantages, the built in designer for once. Cider does not cut it (yet! ), and far less features then Blend. Blend and Visual Studio collaboration still has a long way to go also. I understand the need for XAML (to enable designers to do the ui without the need of strong programming skills) but for certain people like me developing dynamic UI in c# code is so much more intuitive and easy. Since XAML code is parsed and converted in c# code anyway, isn’t there an option to be able to edit this c# code directly (currently it is generated automatically from the xaml file so the modifications will be lost ...Show All

• Visual C# Getting the month out of a string date!

  Hi, I'm facing a small problem and it would be great if someone could provide me a solution to this problem. I have the following code: string str="11/09/2006"; // In "dd/MM/yyyy" format. int month; Now when I specify month = Convert.ToDateTime(str).Month; I get the value of month as 11, which means its taking the "MM/dd/yyyy" format. How can I specify the "dd/MM/yyyy" format so that I get the value of month as 09. I do not want to use the spilt function and get the month, is there any other efficient way of doing this.

• Visual Studio Team System Publish operation failed

  Good day everyone, I have an odd problem when publishing unit test results from both the build server and the developer's desktop. Initial note: All builds and unit test results were succeeding and successfully dropping to the fileserver in the past. In the case of unit tests, even failures were posted to the dropzone (by design, of course ;)). However... recently things have 'gone sideways' :(... here are some symptoms: Build server (unit test publishing): - At build time, I see the test phase start and I can even watch the fileserver's dropzone structure for that particular build and see the TestResults folder created and the subsequent files are copied over (In/Out/binaries etc...). - As soon as the test completes, th ...Show All

• SQL Server Unable to add Securables to a DB Role

  Hi All, I am having problems with a sql server 2005 database. Basic information on the setup, I have two windows user groups, admin and users. These both have logins to the sql server 2005 which are using Windows Auth. They in turn are users inside a database. In the database, there is one Schema that has been used to create all the data tables, stored procs. This was all done back in sql server 2000 days. Now, I have created two roles (one Admin, one Users) and want to add Securables to each of these roles. Essentially, the Admin will have access to all the secureables (except tables - but all stored procs) - and the Users will have access to stored procs that Get data (ie: No updates, deletes, adds). When I add these secureab ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Using Non-XBox 360 Controllers

  As far as I can tell the XNA framework doesn't allow me to use controllers other than the XBox 360 gamepad. In future releases of XNA will the use of other controllers be possible If not, then the framework is fundamentally flawed for those wishing to make games for windows.
