I have MyControl (Grid), and i override IsInputKey method in it.
protected override bool IsInputKey(Keys keyData)<br />
{<br />
bool bIsInputKey = true;<br />
<br />
switch (keyData)<br />
{<br />
case Keys.Left:<br />
break;<br />
case Keys.Right:<br />
break;<br />
case Keys.Down:<br />
break;<br />
case Keys.Up:<br />
break;<br />
default:<br />
bIsInputKey = base.IsInputKey(keyData);<br />
break;<br />
}<br />
<br />
return bIsInputKey;<br />
}
It work ok, but if i place MyControl on other control(TabControl for example), that don't respond to keys.
What i must do?
Thank's to all answers asap!

Does anyone know how you select a pixel from a BitmapImage instance, say the one at 0.0, and set that as the transparent color for a bitmap.
|
|
|
|

Have a look at the Bitblt in Win32 APIs.
thats one way fo doing this, though through Interop in .NET

Thanks for that.
With Windows Forms etc it was easy just
bitmap.MakeTransparent(bitmap.GetPixel(0, 0));
and I'm sure Bitblt would do it but I always try and avoid unmanaged code as it seems like such a backward step especially with WPF and XAML on the horizon.

Wow.And to think I just used to write
bitmap.MakeTransparent(bitmap.GetPixel(0, 0));
Still, that's progress for you.
Thanks for the info, I'll give it a try.

Hello !
I have a question about DB specifications :
Do we have to call IDbCommand.Dispose ?
What does IDbCommand.Dispose mean?
We have problem doing this :
<br />
IDbConnction pipe = new OleDbConnection(connString);<br />
IDbCommand command = pipe.CreateCommand();<br />
command.QueryString = "select ...";<br />
IDataReader reader = command.ExecuteReader();<br />
command.Dispose();<br />
reader.Close();<br />
pipe.Close();<br />
The problem get solved if we don't do IDbCommand.Dispose
Your comments would be very helpful. Thanks.

You cannot Dispose Command Object after ExecuteReader Method, the datareader object maintains the connection to the database as it will not pull all data at once, and it will pull data record by record. So dispose the command object after getting all the data.

Thank you. Anyway, do we have to call IDbCommand.Dispose ?

Whenever a class exposes a Dispose method you should definitely call it as it frees resources immediatly. You can take advantage of the using statement that automatically calls Dispose on an object when execution leaves its scope. Simple example taken from MSDN.
using (Font font1 = new Font("Arial", 10.0f))
{
}

Hi all,
i just want to know how to trim away the last part of a string in a variable...
I have the following:
string strNum = "0821234567,0721234567,0831234567,"
string strNum2 = "";
if(strNum.EndsWith(","))
{
<How Do i trim the last character away? I just need to get rid of the "," at the end>
}

You create a new string from the part of the string that you want to keep:
strNum = strNum.SubString(0, strNum.Length - 1);
---
b { font-weight: normal; }
|
|
|
|
|
Thank you for your time...

Hmm, you should consider using "Trim" or "TrimEnd" instead of "Substring" - after all, you want to - well - trim
It will save you the clumpsy "if" construction as well.

Thank you, the first one worked. so after i checked if there is a "," at the end of the string it just leaves it out. but i'll use the trim end next time.  thanks.

On another note, something faster, and optimized than substring or trimending
(think what shall happen calling substring on a very huge string?)
strNum[strNum.Length-1] = string.Empty;
There are few scenarios where this will be the best and others where this wont be a better idea.

Two problems with your code:
strNum[index] is a char. string.Empty is a string. You can't assign a string to a char.
Strings can't be changed. Hence strNum[index] is a read-only indexer.
So I do not see how this should work. Using a StringBuilder might help if the strings are repeatedly modified, but for a single trim operation it would not make any sense.
