• Windows Forms Setting text programmatically of a databound textbox

  I've a TextBox which is bound to a BindingSource object and use a customer object as the datasource. I found a strange behavior when I change the text of the TextBox programmatically, it does not update the object bound behind after text is changed. Customer customer = new Customer; customer.CustomerNo = "123"; bindingSource1.DataSource = customer; textBox1.DataBindings.Add("Text", bindingSource1, "CustomerNo"); MessageBox.Show(customer.CustomerNo); // display "123" textBox1.Text = "ABC"; MessageBox.Show(customer.CustomerNo); // display "123" too However, if I focus the TextBox and leave it, it will update new value "ABC" to the object.

• Visual Studio Team System Get file attributes - checked out or not (in code)

  Hi, I am wondering if there is any command in the TFS API that lists all files in a folder, and shows whether they are checked out or not. I do know of the QueryPendingSets command, but I would have to combine that with a list of ALL files to get their state - checked in/out. I saw this helpful post about listing checked out files: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=153326&SiteID=1 Is there any API call that allows me to see this in one call P.S. For some reason, the 'Insert Hyperlink' button does not seem to work in FireFox. Hi Eugene, Thanks for the suggestions - I have already looked at the methods you suggested. The GetItems methods does not seem to have an overload that allows me to filter by the state o ...Show All

• Windows Forms Designer form

  Hi-- I'm just learning how to program but I'm already having problems! I saved my program to an hb port and now when I try to open it, I can't find the designer form. I can still change codes and stuff like that but I can't add any buttons to the form. I'm so frustrated but I bet this is probably something really simple. Any help would be greatly appreciated because this is a school project due tomorrow night. Thanks!

• Visual Studio Changing image displayed by image shape programmatically

  Hi all, The dsl i am working on uses an image shape. I would like to change the image displaed by the image shape at runtime. Is it possible Freddo Hi Freddo, It is possible to add an image programmatically to an image shape. First, you need to mark the ImageShape property "HasDoubleDerived" as true and regenerate the code by Transforming the Shape.tt template. Then, add a new custom class (say MyShapeName.cs) to your project and make it derive from MyShapeNameBase.cs (in the generated Shape.cs). Then override the Image getter in the derived class and return any System.Drawing.Image object from this method that will be used as an Image for your shape. E.g. code snippet will l ...Show All

• Software Development for Windows Vista sdk sample - boot image problems

  Using the sdk sample app: "C:\Program Files\Microsoft SDKs\Windows\v1.0\samples\winbase\storage\optical\imapi2sample" I tried taking the image from a boot cd (known to work). Then extracting the boot image. Then burning the data from the disc (temporarily copied to the hard drive) along with the boot image to create a new boot cdr.

• SQL Server Questions about SQL Server 2000 performance, SP 4, reference keys etc.

  Hi, My company has developed a client/server application in VB.NET. The server part of the application runs on a computer with Windows 2000 SP4 and SQL Server 2000 SP3. When running the application and SQL Server during production, the server load is too high, so that the application is not working properly. I consider myself to have a good knowledge about database design (E/R modelling, reference keys, normalization etc.) But I lack the experience from performance tuning and working with this on a daily basis. I understand there are a lot to do regarding SQL Server performace and I am trying to grasp the basics here. So any tips are useful to get me on my way. I have a few questions...

• Visual Studio 2008 (Pre-release) Create new instance of Database all the time, or keep around?

  With the access to the underlying data store being abstracted and relatively hidden from us, I find myself wondering how to manage connection pooling and scalability. I have a static utility class that provides all the methods that generate queries. At the moment, it creates a singleton instance of the Database class (e.g. MyDatabase() , the one created by Sqlmetal) (this is for LINQ to SQL, not EF). Should I be creating and disposing of the database instance within each data request method, or should I be trying to maintain the reference to the static instance of the db My gut instinct tells me to do something like this : public static List<MyData> GetSomething(params) { using (Database db = new Database()) { var x = from .... ...Show All
