you also have to

public override bool ProcessKeyPreview( Message msg) {return bProcessed;}

false = did not handle
true = did handle

I'm not an expert yet, but I play one at work. Yeah and here too.

Hi,

Is it possible to distribute C# class code in separate files as is possible with C++ classes?

The classes in my application are getting bigger and bigger and distributing different functionalities in separate files could help in managing the code.

Thanks,

When this happens, it's best to divide the classes up into multiple classes. However, sometimes that's not possible. The current version of C# does not support this, but the next version will support it.

Caret implementation

I am making a control, and in that I need to implement a caret. I do have problems with that simple task.

First I just want to be able to place the caret in the end of a custom text. I do like this:

float xpos = gfx.MeasureString(string, font).Width
g.FillRectangle(System.Drawing.Brushes.Black, xpos - 3, 0, 1, this.Font.Height);

There is a problem with this. If I use 333 as the text, it goes fine, but do I use 1111111191, the caret is being placed maybe 5 - 10 pixels from the last 1. It seems to me that the size of 1 is measured larger than it actually is.

What can I do about this problem? Am I attacking this problem from the wrong angle? Is there any implementation already made?

Add caret sign to the end of displayed string in paint method -or- add it to the string in setting Text property and remove it in getting this property.

That is not really a good solution. Having a carrot inside a word, makes it look a little strange when the carrot blinks.

I found a solution using API calls to old GDI.

You now there are actually two ways to get a remoting application up and running: via a web server or a host utility. The first approach needs using IIS and your question is about this one.

I hope you have below files:

1- SomeServer.cs and its corresponding web.config file. put these all in some folder like "MyServer"

2- SomeClient.cs and its corresponding SomeClient.exe.config file. put them again in some directory like this: "MyClient"

3- Next create a folder named "bin" under the MyServer directory.
put the compiled version of SomeServer.cs which is SomeServer.dll in this bin directory.

4- put the compiled version of SomeClient.cs named SomeClient.exe in that MyClient directory.

5- Use internet services manager to create 2 virtual directories for both above mentioned directories.

6- Run SomeClient.exe

If any thing is not clear tell me.
I hope this helps. Rose | [Rose]

THanks Meisi, Of course you don't need put client part under IIS, and I think the server part need some exe file to respond to client, does IIS do it?

How to load an image from a url into a PictureBox.
Thank's

Mazdak22-Aug-03 7:27

22-Aug-03 7:27

You have to save it as a Bitmap,then set the Image property of PictureBox to it.Something like this:

picturebox.Image = Bitmap.FromFile(urlpath);

I think you would just need to reference the System.Web library.
