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...

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

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();

Forgot to mention that you'll also have to reference the System.Runtime.InteropServices namespace to use the DllImport attribute

hey mazi,
when i look through this forum, i think it would be a good idea for you to buy the petzold-book. it is nice to read and full of information.

LOL!
I'm just without a job at the moment so I spend a lot of time coding (with CP in the background) or reading CP.

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 don't think so, I'm pretty sure you'll have to use Managed C++ for this. I'm not sure if you can export a __gc method, but you can export a regular method which calls the __gc one.
This is the real power of MC++, you can make calls to both sides easily

I can create a 256 color icon (w/o hotspot) and use it as a color cursor.
I can create a 16 color cursor (w/hotspot) and use it as a color cursor.
But 256 color cursors are coming in black. Any thoughts?
Thanks.

Finally got it to work. Had to use an outside editor (Michaelangelo)

This should be absolutely simple, but I'm on a diet and I'm cranky...
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.

Yep, it truly thinks that its editing an icon file.

Well, glad it's not the SlimFast...
Little investigation shows that creating a new 'Cursor' actually just creates an Icon instead. You can copy an old cursor into it and change it and then it works (ok).
It does NOT support 256 color cursors, only 16 color ones. (ugh).

hi, strange thing this:
i have an mdi-app and want to scroll the child-windows by use of the cursor-keys (which is kind of natural to me and a few others)  . but i get no key-down-event for the cursor-keys in my mdi-child. i have played around a lot with the following results:
in non-mdi-environments (simple form) everything is ok (compare to petzold: chapter 6, SysInfoKeyboard) 
switching back to mdi: even in the mdi-parent form (the outer "container") i get no Keys.Up/Down/Left/Right - messages. but only if there's no modifier pressed. means: "ctrl-up" or "alt-down" do reach the child-window  , but it seems that someone blocks the simple cursor-key-pressed-events, when i enable the IsMdiContainer-property of the main form. 
anyone any idea?
:wq

If you override IsInputKey/IsInputChar do you still see that problem?
Try overriding it in the MDI child first, then in the parent, then in both.
HTH,
