• Windows Forms ReadXml with ProgressBar

  Hi, i am getting a stream from a ftp server... I am reading this stream to a dataset... My stream is about 4-5.MG, so i have 2 options: To download my xml file from the ftp server, to save it localy on my computer. In this way i can make a progress bar of my recived data... and i can know how much time left... The other way is to read the stream directley from the FTP server... This way is better because of the performance. But in this way i can make only a progress bar that is moving left and right (marquee)... Is there a way to read the stream from the FTP server, to my local computer without saving a file on my drive ...Show All

• Visual Studio Express Editions how to code to make application icon goes to WINDOWS notification area when "minimize" is clicked in c#.net 2005 ?

  some programs can be moved to notification area instead of just go to taskbar when "minimize" is clicked, how to do this with c#.net2005 windows form applications plz help Take a look at what the NotifyIcon provides for you ( http://msdn.microsoft.com/library/default.asp url=/library/en-us/vbcon/html/vboritrayiconctltasks.asp ). With a little extra logic in your forms Resize event handler, you can check the value of WindowState and hide the form when minimized and show it when it’s coming back from being hidden, all the while toggling the Visible property of the NotifyIcon. ...Show All

• .NET Development C# 2.0 Convert Bitmap to Icon

  Hi There I am using .NET 2005 Beta 2, and am trying to write a utility program that converts icons to bitmaps.  The following function creates an icon file OK, but the icon file is not properly formed.  When I try to open it using Visual Studio I just get a heap of jumbled characters. public void BitmapToIcon(string sourceFileName, string destFileName) {   // Create a Bitmap object from an image file.   Bitmap bmp = new Bitmap(sourceFileName);   // Get an Hicon for myBitmap.   IntPtr Hicon = bmp.GetHicon();   // Create a new icon from the handle.   Icon newIcon = Icon.FromHandle(Hicon); &nb ...Show All

• .NET Development Did asynchronous execution change in 2.0

  hello, i have this code that called method asynchronously through the delegate class with the begininvoke and endinvoke methods. Exceptions could be thrown withing the methods which were always caught by the framework and rethrown when endinvoke was called. Has this now changed as my exceptions are no longer being caught and rethrown, and just bringingt the whole app down as they are unhandled. he is sample code that i use to denote the changes. .net 1.1 /// <summary> /// Summary description for Class1. /// </summary> class Class1 { private delegate void ThrowExceptionDelegate(); private static bool stop; /// ...Show All

• Smart Device Development Serial Port DataReceived Event in .Net 2.0

  Hi there, This is driving me crazy, I cannot seem to get the DataRecieved event to work on the Pocket PC using the new serial port class in Visual Studio 2005 with C#. The DataRecieved event just never seems to be called. I can write data to the port just fine. Here is some very simple sample code that reproduces the error:. using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.IO.Ports; namespace SerialTest {     public partial class Form1 : Form     {       ...Show All

• Software Development for Windows Vista Creating Vista-like applications .. Which SDK/API to use?

  This maybe a silly question, but what API/SDK do I use to create Vista-like applications I mean following the Vista UX style guidelines; creating the open/save dialogs like we have in Vista, changing the look/feel of various controls, etc. I know for sure WinFX is not the one...since this is not a platform SDK. There's a platform SDK( Longhorn Beta 1) on MSDN, but it just looks like a regular sdk (nothing special). A easy example is how do I get the File->Open dialog you see in the latest Vista builds (I am using the Vista beta 1 build).

• .NET Development NullReferenceException when accessing DataTable.Rows

  I feel sure there must be a simple explanation for this that I am missing, but I have searched the help files and Googled for HOURS and I'm at a loss.  So I'm hoping someone out there can see what I'm missing.  I'm trying to get data from a table in a dataset and build a string, which I will later write to a file.  But when I try to access the rows in the table, I keep getting a NullReferenceException.  I've tried several different approaches, all copied straight from .Net help files, but I always get the same error.   I know there is data in the table because I displayed it in a datagrid with no problem.  ...Show All

• Visual Studio Team System Load of fxcop input assembly failed

  In Vis Studio 2005 beta 2 I receive the 'Load of fxcop input assembly failed' when I open my c# project. I have read the material at the thread shown below http://forums.microsoft.com/msdn/ShowPost.aspx PostID=2386 It does not seem to apply to my project, as I have the output path under the project directory.

  I had a *quick* look through the Tools > Choose Toolbox Items... menu but the list is far too big for me to check out every single item. My question is; is it possible to use the editing component from the IDE in our own applications I want to build a nice script editor for my application with code folding, syntax highlighting, intellisense, etc. I don't mind how the colouring is done, even if I have to add my own RTF code at specific places or similar, it's the code folding I'm interested in.
