Is there way to change the color of the headers in a ListView? Any suggestions, code, links.
Thanks in advance.

With thanks to Daniel, and others, I have a combo box which lists all my databases, and I am able to get a list of tables with this code:
ComboBox cb = (ComboBox)sender;
m_conn.ChangeDatabase(cb.Items[cb.SelectedIndex].ToString());
SqlDataAdapter dataAdapter = new SqlDataAdapter("select * from INFORMATION_SCHEMA.TABLES", m_conn);
dataAdapter.Fill(m_dsTables);
Now all is good, except that as m_dsTables is bound to my grid, when it updates, it keeps the old values as well as displaying the new. This is not what I want - how can I get the DataGrid to reset itself ? Is it something I've misunderstood about how I am working with the dataSet ? I'm thinking so, but any help would be appreciated, coz I am not sure at this point in time what is going on....

I think someone asked this earlier and the answer was to un-data-bind it which clears the DataGrid, then you can bind it again and it should then not have the old data-items.
Not sure though, will try it this evening.
[edit]
Just read this 4GysFromRolla.com article and it mentions clearing the database to stop this happening.

IIRC, Fill doesn't clear out the existing rows in the underlying DataTable.

I'd do a m_dsTables.Clear() before the fill operation.

Hi,
I would like to create a context menu when a right click on a simple button or any other control. I need this menu with few options to execute other code.
Does any one have any little sample code to do this or maybe some reference?
Thank you in advance,
Edgar

The "Text" property is not showing up for one of my custom controls, although other properties show up. If I make my own "Text" property, the compiler tells me to put the override or new since my parent has the same property. HOw come it does not show up (although many inherited properties show up)? Does it have anything to do with some attribute?

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

try this attribute on your custom property.

I found about 10 syntax coloring/highlighting articles here on codeproject, but none are for C#. I've been trying to get RichTextBox to do it, but it always ends up being too slow, disrupting the user while the user is typing, if the file is medium sized like 40k. It's not really possible to do with richtextbox in c#, because the interop to do selection is so slow.
Anyone working on such a control or does anyone know of one?

You can take a peek at how SharpDevelop[^] does it.

i want to creat a dir in system32 dir is it the right path
is there any changes in %systemroot% require for path?
%systemroot%\\system32\\
r00d0034@yahoo.com

No, that should work. You could also use %windir%\\system32
A good way to check this type of stuff is to type the environment variable in to the Start|Run... box. That will put you right in the specified directory. Or, if you wanted a .NET way to find the System Directory, you could always do System.Environment.GetFolderPath(SpecialFolder.System);

these are the strings that i want to convert them into integer value but they also contain characters and speces and sentances. how to convert valied strings into int?
can any body tell the good check so that ?
is there any way to neglect character in a string?

Well, first off, you would have to remove all the non-numeric characters. Then you could do System.Convert.ToInt32(string); where string is the string that you want to pass in.

I'm sure that ToInt32 would throw an InvalidCast exception, you could use a try catch to catch them, or use a regular expression to strip all non-numeric content. PLan A is a hack, plan B would take a tiny bit longer to impliment.

You sure did, but while imran has been here for six months, in that time he does not seem to progress beyond asking the simplest of questions, and not explaining HOW to remove the characters is just begging for another post from him, so may as well answer it all at once. 
In fact, he's now asked the same question in the C++ forum. I'm not sure if he was lost when he posted here, or if he's decided to change languages for this project after looking at the RegEx help in MSDN....
It's funny how often you answer a question though, and a day later, someone else posts the exact same answer to the same question.

I guess you were using .NET, seeing as you asked on the C# forum. Duh. The point is, is how easily you can do some simply string mashing a good reason to choose one language over another ?

Sorry, don't have one. I've managed to avoid the IM thing. I ran up Sonork last night when CP when down, but I usually don't run that ( and certainly not here at work ).

 Why? It's really convenient. I wouldn't have known about this little fiasco here had not James alerted me via IM.

Check my post count now, and tomorrow. Then ask yourself, if this man had IM, would he get any work done at all ? Plus work frowns on it.
