Subclass DataGrid and override the PreProcessMessage method

public override bool PreProcessMessage(ref Message msg)

Keys keyCode = (Keys)(int) msg.WParam & Keys.KeyCode;
switch (keyCode)

Hi,

I am having a list url in a text file.These url are utf8 encoded.
eg. http%3A%2F%2Fwww.abc.com%2Findex.htm

I need to parse these and convert it normal string like

http://www.abc.com/index.htm

Is there any way for doing this ....

Thanks in advance

That's not UTF-8. That's URL hex encoding. Use the System.Uri class to convert to a canonical representation.

No, they are not utf8 encoded. They are url encoded.

Use HttpServerUtility.UrlDecode() to decode them.

Is there any other way of doing this ..

To use HttpServerUtility one needs Server object...

You can also use HttpUtility.UrlDecode().

C# Remote process on client machine

Hi all,

I’m currently developing a Client/Server application based on Socket, on which the client runs a UI and submit some request which will be send to the server then the client exit. Then the server manipulates these data on his side.

1. I’m trying to force a simple dialog to run at the client machine, on which the user provide an answer from that dialog (Yes/ No) and click O.K.
2. The server then receives this feedback and does something.

I need some help on this issue, I’ll appreciate it. Thanks

Kind Regards,
Mohammad

Display HTML without webbrowser control

I want to render simple HTML on a form without the overhead webbrowser control.

I'd like to render IMG, H1, TABLE tags - and ideally INPUT tags too.

I appreciate that implementing a full web browser is no simple task, but this is much simpler.

Anyone come across any suitable code (even in another language)?

Thanks

Robin

I'm also looking at Karl Runmo's article http://www.codeproject.com/cpp/krhtmlviewer.asp which renders tables too.
If I get a .net version working, I'll post it up here.

Hi,

In a relational database, I would to like to know the performance difference between of using a string and an integer as the primary key field for the tabl;e. Will a column field of integer be indexed faster than a string column field ?

Thanks

Receiving same udp datagram twice

Hi!
When I try to send udp-packets broadcasted in my local LAN by this code:

<br />
Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);<br />
s.SendTo(Encoding.ASCII.GetBytes("Some text to send"), new IPEndPoint(IPAddress.Parse("192.168.0.255"), 11000));<br />

And do the receive with this:

<br />
client = new UdpClient(11000);<br />
IPEndPoint EP = new IPEndPoint(IPAddress.Any, 11000);<br />
byte[] buffer = client.Receive(ref EP);<br />

I always get two messages received! My explanation for this is, that udp is connectionless and by broadcasting it it's returned by some other device - I don't know.. Can you explain it to me and give a tip how to avoid it?

System.Windows.Forms.ListBox .net 2.0 problem

Shane Stevens14-Aug-05 17:54

Hi,

Is it just me or does the ListBox class in .net 2.0 exhibit some odd behaviour?

For instance, when I use the mouse wheel to scroll it seems to do some weird redraw-from-the-top update method.

Also, it flickers like crazy when resizing. I've tried enabling the double buffering mode to no avail. I have overridden it to draw icons next to the text which works fine, but it seems to clear the entire background, not just the dirty area, every time.

As a sanity check I then placed a stock ListBox control on a new form to see if it works in its standard mode but it exhibited the same symptoms. The odd thing is it doesn't do this with .net 1.1. Confused | :confused:

Does anyone else suffer from this or know of a solution?

Regards,
Shane
