I've just started learning how to use the Entity Framework to write a very simple C# network monitoring program - this is a learning exercise to try and "drive home" what I've only read about to date. I'm also new to C# and LINQ (just to complicate things further.) I believe I have the data model suitably normalised but I may be wrong. ...
Hello, The point is to notify the user using the memo when a packet is received/sent in a TCP Client. The old code was extra dumb,I used a Timer that used to add text in the memo since the Timer has access to the form members,lol. The old code: //Memo.Text += txt + "\n"; I played with it today,this is what I've done In Form1's clas...

Hello, The Idea is to notify the user using the memo when a packet is received/sent in a TCP Client. After couple of fixes,the most suitable solution seemed to be this one public string TextValue ...
I have a custom WinForms designer, and I've just added functionality to create duplicate components using drag & drop (with the ctrl key held down) by inheriting from CodeDomDesignerLoader. Unfortunately, this works a little too well: the new components get all of the same property values as their originals, and I need some of those to b...

I am showing Dialogs with Form.ShowDialog(). Forms are set to TopMost. Some image processing calculations are performed asynchronly in the background. Their results are rendered in the main form by Invoke. So far so good. Strange thing is that every now and then the modal dialog is moved behind the main form. I guess that happens when th...

I heard from a friend that asp.net relies on/uses a Windows forms class. I tried to figure out which class that might be. The only class I found was System.Web.UI.WebControls.FontInfo with the property public string[] Names that has an Attribute Editor("System.Windows.Forms.Design.StringArrayEditor--snip") Is there a reference to the...
I have to create variable number of Labels and next to them TextBox controls - arranging the whole thing into a column, each line a Label and a TextBox.

If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My q...
I'm creating a routine that allows the user to replicate keyboard shortcuts into a textbox for 'custom keyboard shortcuts' customization, but every time the alt key is pressed with another letter, it produces another sound. I'm capturing the keys in the textbox_keydown event to parse the modifiers + other keys into a readable Shift + A...

We're working on a Windows App that periodically has to launch operations which may take some time. We've gotten into a pattern of having these operations run on a BackgroundWorker, and writing up a quick WinForm for each operation, where you pass in to the form the necessary parameters, the form wires up the BackgroundWorker and makes ...
I'll start by what I'm trying to have happen: I have data loaded in a range, where, say, scrolling all the way to the left puts me on April 1, and scrolling all the way to the right puts me on June 1. The user positions the scrollbar on April 1st, and clicks the left arrow on the scrollbar. Now the scrollbar is positioned at March 31,...

I have the following simple scenario: A DialogForm with a Button, the Button_click throws an exception. A MainForm with a button and a Label, in the click I show a new instance of the DialogForm inside a Catch block. If I run this setup in regular WinForms, I can catch the Exception as expected. If I run this in WinMobile (I've test...
