From what I can tell from the documentation, named matches is not supported.

Try using the pattern "(.+(?<=/))" and use the index of the match in the replace: "$1".

I found out what I was doing wrong. I need to match the whole string (not only the part I wanted to extract). So I added a named variable called <rest> to match the rest.

This my current version:

<br />
// Takes an url and returns the path. can both handle http://www.mypage.com/folder/ and http://www.mypage.com/folder/somestuff=blabla?etc<br />
private String stripFromUrl( string url )<br />
	{<br />
		String stripUrlPattern = "(?<fixedUrl>http:// [ \\w \\. / ]+) (?(/) (?<rest>.+) | (?<rest>(?<=/).+) )";<br />
		Regex r = new Regex(stripUrlPattern, RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace);<br />
		string stripurl = r.Replace (url, "${fixedUrl}");<br />
		return stripurl;<br />
	}<br />

SOLVED!!

Another alternative would be using the System.Uri class (check the Path property).

I use System.Uri to get the returned url but it returns the filename and parameters also. I'm Changing relative paths to absolute. That's why I need Regex to strip the filename off the Uri.

Why .net requires .dll file ?

Hi,

Here i am facing one problem in making .exe file,whole situation is like below.

My main project is in C#.net and i had made .dll file from that,now client requirement is that,he wants to run the .exe file of our project from vb 6.0 but that must be console application so i had made .dll file from my project and one another .net project include that .dll and then i made .Exe file of that project which is .net console application,it means that my second project is includes .dll of my project and now for testing purpose i had made third project which include second projects only .exe file but now problem is that third project also required first projects .dll otherwise it is not working.
Here is 3 project's outputs and included files.
first project : out of that made .dll file.
second project : made console application and include first project's .dll file and then made .exe file
Third project (for testing) :if i include only second project's .exe then project is not working and if i include second project's .exe and .dll both
if working fine.

Now my question is that why my third project required .dll of second project,actually third project should not required .dll file ,only .exe of second project is enough.

hope you not confused with all of above.
if any query regarding understanding pls ask me.

Perhaps a little more punctuation would help?

From what I understood, you have 2 executables and a dll. One of the executables is linked to that dll, the other only uses the first executable. If you are asking why the dll is needed, you haven't understood dynamic linking.

DLL (dynamic linked library) means that linking (resolving method names to addressed) takes place when the executable is loaded into memory. Which obviously means that the dll has to be available when the executable is loaded.

Does this make sense?

You will need a COM library for that. I think it's called ADOX.
Here's an URL for a VB6 example. Shouldn't be hard to translate it to C#

Dont use this. You are obviously refereing to the container (parent) Control or the Form hosting the control.

Set the form's Accept button property to the "sign in" button. That should do the trick.

Launching a form with visible set to false

Sharpoverride3-Jul-05 23:25

My problem :
I use a notify icon on a form .. and I want to only show the notify icon and not the form ... but I didn't have any success cause the form tries to open as visible

The only solutions I came up with are
1.to start a timer on form load
2.override the OnVisibleChange method and set visibble always to false

I think the cause for the error is Application.Run( myform ) or probably an error with .NET Framework wich I doubt

Is anybody else experiencing this or I 'm the only one who gets this king of errors .
I tried to set visible false in the constructor but it still shows the form ..

This error comes up in .Net 1.1 , 2.0 Beta2 , haven't tried it on 1.0.. but i'm pretty sure it's the same

If you want to see that I'm write ... create a new C# project ... and in the form constructor write
,.....
this.Visible = false

......

Laugh | :laugh:

Ok... if someone can tell me why ... or if they have a more viable solution I'll whait for it

have you tried this.Opacity = 0;

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
