Onwer drawn caption bar? - C# Discussion Boards

23-Mar-03 19:53

Something went wrong in the registry of my computer. All of a sudden
I cannot compile C# any more. At line 0 of the first source file
fatal error C1102 is generated and the error printed with it
(translated to English) is: "class is not initialized".

When trying to make a new C# project the project cannot be opened and
the error "cannot create the C# compiler" is printed. The suggestion
by the system to repair the installation via the Set-up did not work.
Deleting the C# compiler and then re-installing did not work either.

Next step that I have not taken yet would be to delete all of the
Visual Studio.NET and then re-install.

Then the next step would be to start from scratch with Windows-XP.

A search on the internet also yielded nothing.

Anyone has a better solution?

Do you get the same error running csc.exe from the command line? If so, then the problem is with the C# compiler itself and you need to just reinstall the SDK, not all of VS.NET. However, if you can use csc.exe from the command line, then there's a problem with VS.NET and you need to reinstall that.

I deleted the Visual Studio and re-installed the Windows Components and the Visual Studio again and
the problem is still there. I sent the question to Microsoft. Let's see what the answer is...

Growing a TextBox to fit text

31-Mar-03 21:52

The following is the last part of a discussion with the
Microsoft help desk:

---
to start with the good news: the C# environment is working properly again.

As you suggested I re-installed the Windows Components Update and then
re-installed the Visual Studio .NET.
Then I tried to create a new C# project, but it still did not open....

When I looked at the re-installation log from the Windows Components
Upgrade I saw that it found that there was nothing to do.

Then I selected

Control Panel->Add/Remove Programs->Microsoft .Net Framework

and I REMOVED the .NET Framework.

Then I installed the .NET Framework again and re-installed the
Visual Studio .NET again.
Now everything works as usual.

Thank you for your support.

Dear experts,

I am trying to create a class that is derived from TextBox that has the ability to automatically resize as text is added to it. It is for use within a diagramming style application.

When the TextBox is created it will have a default width and height (Height is set to allow one line of text to be visible). As the user enters text and reaches the right hand side of the TextBox, I need to increase the height of the text box to allow the second line to be seen and so on. The reverse behaviour is required as text is removed, the box must resize to be the minimal size required to show all lines. Also, the TextBox has the multiline property set to TRUE. I cannot use scrollbars as the user must be able to see all text all once. I've checked the .NET documentation and have not been able to locate a property or event that will allow me to detect this situation and take the appropriate action.

Even the textbox underneath icons on the Windows desktop has the behaviour that I need! If there was anyway of re-using this, it would be great!

Please help! Thanks in advance Wink | ;-)

Benjamin,

Try the following:

Initialise a local field, default to the usual height of the textbox:

private int _InitialHeight = 20;

In the constructor of the derived class:

<br />
this.Multiline = true;<br />
this._InitialHeight = this.Height;<br />

Then override the OnTextChanged Method:

		protected override void OnTextChanged(System.EventArgs e)<br />
		{<br />
			//Get graphics<br />
			System.Drawing.Graphics g = this.CreateGraphics();<br />
<br />
			//Get size<br />
			System.Drawing.SizeF s = g.MeasureString(this.Text, this.Font);<br />
<br />
			//Get the number of line (on top of the original 1), which need to be viewed<br />
			int lines =  Convert.ToInt32(s.Width) / this.Width;<br />
<br />
			//Work out the height the control must be to view all lines<br />
			int height = (lines * Convert.ToInt32(s.Height)) + this._InitialHeight;<br />
<br />
			//Set height<br />
			this.Height = height;<br />
		}<br />

I hope this does what you need. Let me know if you'd like elaboration on any point. Note that this does not take into account the user using the enter key.

Not really the place to ask that question, but here goes:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

I'm afraid the WindowsInstaller ones are in the GUID-looking keys, so you need to select each one until you find the one with the right DisplayName.

Or you could write a quicky app to loop through them and find it. Roll eyes | :rolleyes:

Use jv16 Powertools (www.jv16.org[^]). The registry cleaner section will pop up and show you the list of "Installed Programs"...you can select and remove them. Smile | :)

Ok I know how to get a file from the net... I mean how the fetch the data inside of it? I mean getting some rows or applying an SQL query or whatever???

David Stone23-Mar-03 13:02

Ah, okay. Totally misunderstood your question. Blush | :O

Anyway, what you would do is use the System.Data namespace and the System.Data.OleDb namespace, then use the OleDbCommand object to set your select query (a SQL Statement) and the OleDbConnection object to connect to your data, and the OleDbDataAdapter to grab the data and put it in a DataSet object.
