Senkwe Chanda19-Apr-02 0:01 Senkwe Chanda 19-Apr-02 0:01  When I run this, C# using System; namespace trim { public class trim { static void Main() { string str = "Senkwe "; Console.WriteLine(str.Length); str.Trim(); Console.WriteLine(str.Length); } } } I get an output of 10 each time. Am I using trim improperly? I even tried specifying an array of characters to be reomoved ie char[] myChars = {' '}; and it still didn't work. Any ideas? Regards Senkwe Just another wannabe code junky Re: does Trim() work?? Rüpel19-Apr-02 1:21 Rüpel 19-Apr-02 1:21  Trim returns the new string! str=str.Trim(); should be the solution i got into this trap with the Registry-class: when you want to open a subkey you would write key.open(location); but instead the handle to the opened key is returned. so key=key.open(location); worked. in general: someone has to explain to me, what the idea behind this weired design is? this behaviour of returning the result looks to me like a static function (like Color.FromArgb()) - which Trim and this registry-open-function are not. i don't like that design - and obviously i'm not the only one, that was caught in that trap... :wq Re: does Trim() work?? Senkwe Chanda19-Apr-02 2:19 Senkwe Chanda 19-Apr-02 2:19  Thanks alot! Boy, that was so un-obvious to me. To make matters worse, the documentation had no real examples of how to use it. I agree that it is wierd and inconsistent. Thanks again Regards Senkwe Just another wannabe code junky Re: does Trim() work?? ez219-Apr-02 3:05 ez2 19-Apr-02 3:05  My guess as to why it works this way is that strings are immutable (can't be changed). So methods that apprear to change the string actually return a modified copy. The original string stays intact which is why you needed to assign the returned modified string to the orginal string variable (i.e. str = str.Trim(); Re: does Trim() work?? James T.

Funny, because I *have* a job, I spend a lot of time coding with CP in the background..... ( Well, actually I do the same at home, so that's not quite true ) I'm trying to figure out how to improve my screensaver and I wonder if I can link to the dll that handles screensaver behaviour, and hijack the message loop to handle the messages I am supposed to. Does that sound viable to you ? The instructions in MSDN tell me to do this: Creating a module-definition file The ScreenSaverProc and ScreenSaverConfigureDialog functions must be exported in the application's module-definition file; RegisterDialogClasses should not be exported, however. The following example shows the module-definition file for the sample application. Can I *do* this in C# ? My main reason for wanting to is simply that as it stands I do not have multi monitor support and I can't see a way to find my other monitor/draw on it.

I just did 'Add - Add New Item - Cursor File' to my project. The cursor comes up fine, and I can edit it, BUT the stupid 'Set Hot Spot Tool' never lights up and I can't set it. When I look at the properties of my cursor, it says 'Icon File'. The name of the file is 'cursor1.cur' What is going on?! Thanks. Re: Hotspot for a cursor object James T.
