• Windows Forms Combobox - set value from recordset

  I have been writing apps in Access for years but .Net is driving me crazy. I have a form to edit an existing record in an Access back end. I like to use combo boxes to display the current value and allow the user to change the data within the list of the combo box source. I've managed to get the comboboxes to have a record source based on an access table having the integer value hidden and the understandable-by-humans value as the display column. Having pulled the record to be edited into the form I cannot set the combo boxes to the current value of the record in the recordset. I'm trying to use the code like: Me.MyCombo.ValueMember = MySet.Fields("MyValue").Value The compiler tells me that Option Strict On w ...Show All

• .NET Development Creating new threads in static constructor

  I have the following test program: static void Main( string [] args) { new TestThreadPool (); Console .WriteLine( "Done" ); Console .Read(); } In the "TestThreadPool" class I create a new thread which outputs a message, sleep, then return: class TestThreadPool { public TestThreadPool() { WaitCallback callback = new WaitCallback (MyCallback); ThreadPool .QueueUserWorkItem(callback); Thread .Sleep(10000); } private static void MyCallback( object state) { Console .WriteLine( "in callback" ); } } This of course works as expected: I immediately get the message "in callback" written to the console; then, ten seconds ...Show All

• Smart Device Development Picturebox resize scrollbars

  Hi. if I have an image showing in a picturebox, of course depending on the image size itself, if the image is larger than the screen, I have told it to resize the picturebox to the size of the image. This is all cool, and shows me the vertical and horizontal scroll bars. problem is, I am unable to scroll through the picturebox. How can I scroll through the picture box so I can view the image didnt really think it would matter but I guess it does! But thought it still wouldve had the same functionality - scrollbars appear therefore you should be able to scroll. :-) ...Show All

• Visual Studio 2008 (Pre-release) Native PODs in C++/CLI as MC++?

  Hi, It seems with a refocus of C++/CLI, that Orcas may improve C++/CLI for the interop scenario (i.e. the bridging between native and managed code); as mention in this thread http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=970938&SiteID=1 ... So, have you guys taken a fresh look at feedback # 114649: Feature regression from MC++ to C++\CLI (unmanaged PODs are not supported in ref/value classes); http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx FeedbackID=114649 This is such a blocking issue for us, as we desperately want to migrate our MC++ code over to C++\CLI. I know that Brandon Bray and/or Herb Sutter talked about this grandiose dual memory class layout to allow mixed types, but I don't need this to work ...Show All

• Visual C# DataGridView and media files

  Hi I want to have a column in a datagridview, which contains various mediafiles such as text, audio, video (it can be any). Now if a user clicks on such a cell - let's say it's an audio file - I want the standard media player to open and play this file. The datagridview gets its data from a database. It should work similiar to Explorer (or any other file manager), where I click on a file and the corresponding application is opened to view the file. Is this possible How Thanks! you need to get the cell value they clicked on and pass the contents of that cell to the Process.Start() method as suggested but of course, it must be a valid path to the file as well as being a valid registered file type for ...Show All

• Visual Studio Feature request: Referencing Code Samples

  I often add example-code to the code comments showing how to use a certain function. The problem is that if I refactor the code, the example will be incorrect and there is no way of checking the example code with the compiler. Usually what I do is creating a bunch of methods that uses the functionalities and copy/paste that over into the summaries. This is a pretty stupid way of doing it though (because of the human factor involved). So this is what I propose: 1. Create a code sample file that compiles, and has parts of the code marked by regions: public void Example1() { #region Example1 myObject = new myObject (); myObject.Invoke(); #endregion } 2. Reference the region in the code summary: /// <example>Create a ...Show All

• Visual Studio Express Editions Browser waiting

  I'm trying to put together a relatively simple script for a webbrowser game that provides a service in-game by interacting with the site and doing some stuff with the material within it. I have gotten around most of the problems of how to make it work, but there's one thing that I don't know how to do properly: making the script wait for the browser. In short: I'd need some way of making the script check that the browser has finished downloading the page before attempting to do anything else. Here's a snippet of what I currently have: Public Sub Form1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles MyBase .Load WebBrowser1.Navigate( "http://www.WEBSITE.com" ) End Sub ...Show All
