I need a TextBox or some type of Multi-Line Label control which will automatically adjust the font-size to make it as large as possible and yet have the entire message fit inside the bounds of the text area. I wanted to see if anyone had implemented a user control like this before developing my own. Example application: have a TextBox ...

In a Winforms application (C#2, FX2.0, VC2008) I am using a Panel derived Control to display custom controls. The controls are arranged vertically and there are usually more than fit in the visible area of the panel. I have drawn a litte sketch of it: Sometimes (usually after scrolling inside the panel) rectangular areas appear to ha...
(This is probably a dumb question AND a WTF combined, but here goes nothing) I want to 'draw' lines or areas in my interface - typically separators inside a TableLayoutPanel. Currently what I do is just dump a Panel in the row and set it to Dock=Fill and give it the background required colour. Just before doing the same thing, I wonder...
I've seen several articles/blog posts that advocate the use of the System.Web.Caching.Cache in applications that are not for the Web, however, the MSDN documentation quite clearly states that The Cache class is not intended for use outside of ASP.NET applications. It was designed and tested for use in ASP.NET to provide caching for ...

I want to show a dialog, blocking the method that shows the dialog. Then when the user clicks the 'Finish' button on the dialog I want: The dialog to remain visible. Control to return to the...
How can I hook in the ErrorProvider with individual cells on the DataGridView control? ...
I have a somewhat complex UserControl, and Visual Studio 2008 is giving me a rather harmless annoyance when working with it. Every single time I open the control with the Designer, it decides to immediately change some of the harmless values set by the designer - namely the initialization of Size properties. If I save those changes, cl...

It works fine on Auto...
I'd like to show an animated GIF as the tab image on a TabPage. If I add my image to an ImageList and use the TabPage.ImageIndex property, it only shows the first frame (and doesn't animate): ImageList imageList = new ImageList(); imageList.Images.Add(Properties.Resources.my_animated_gif); tabControl.ImageList = imageList; tabPage.Ima...

According to the official documentation, the KeyDown event on a Windows Forms control occurs only once, but it is easy to demonstrate that the event fires continually aslong as a key is held down: private void textBox1_KeyDown(object sender, KeyEventArgs e) { label1.Text = string.Format("{0}", globalCounter++); } H...
Hello, What is the difference between GTK# and windows forms? Are they totally different? Thanks ...
I want to develop a StringConverter with standard values, which after attaching it to a PropertyGrid will act like comboBox with autocompletion. The example below will give me a comboBox, but without the autocompletion - user have to expand it and choose manually one of the items. Is there a way to allow user to type the beginning of one...
