hey guys! (sorry about my english)

so, i know the great tool dcomperm.exe, but i don't want use this .exe..

what i realy want is: to use a .net assembly with all existing functions on dcomperm.

so i just start to rewrite my own dcomperm in c#, but..! its a LOT of work.. its almost insane... OMG | :OMG:

1- so, anyone know a finished .net component or something like that??

2- i try to convert the C++ unmanaged dcomperm code(from samples VS 6), to
C++.net, but im not so close to C++ code, its a hard work.. it would be a easer workaround??

thanks a lot guys..

if i get finished my own dcomperm, i'll build a codeproject article
to share it!

blitzkrieg bop!!

Breaking a string into separate words

Hi Using C#, how can I break a string into separate words. For instance, " my search string, and some-other-string"
becomes "my" "search" "string" "and" "some-other-string"

Notice, that I have removed spaces and commas, but kept the dashes in my words.

So any idea how I can remove spaces, commas and break a string into separate words??

Kind regards

You can do it by using Substring() method, or by Split() method, but the last one requires that there is a separator, this separator may be the " " Char.

"Praying." Is this only what I can do for him ?

If your string is not that large, you can use the Split[^] method on System.String. Something like

string []words = sentence.Split(new char[] {' ', ','});

You need to watch out for empty strings in words though, two successive delimiters will result in an empty string.

If your string is large or your parsing logic is complex, you can try using theRegex[^] class.

i need a file stream object but just in memory.
That is i dont want a StreamWriter that write a file on the HD or a StreamReader that read one from the HD, i need:
Stream mstream
but i can't becouse i can inistialize it with:
new Stream();

so how can i do?

Re: use a file stream just in memory

S. Senthil Kumar21-Oct-05 1:49

Use the System.IO.MemoryStream[^] class. StreamReader accepts any stream, so you can pass a MemoryStream instead of the FileStream.

ImageList not working

21-Oct-05 1:02

Hey everybody!

I am trying to create an ImageList to add pictures to my toolbar.

I am doing that using the design mode of VS.net.
anyway, after I am adding an Image to the ImageList, VS adds this code to the properties of the ImageList object:

this.imageListToolbar.ImageStream = ((System.Windows.Forms.ImageListStreamer)(resources.GetObject("imageListToolbar.ImageStream")));

and when I run the program I get "System.Reflection.TargetInvocationException" exception in this line.

I really have no idea why it happens or how to fix it... Sigh | :sigh:

can anyone help me with that????
THANKS!

Re: ImageList not working

S. Senthil Kumar21-Oct-05 2:03

21-Oct-05 2:03

Did you change the namespace or classname after you added the image list? I've seen that cause problems. If you did that, try changing the "Default Namespace" entry in the Project properties dialog to the new namespace.

no, I didn't change anything like that.

I get that error even if I am openning a new project, and adding an ImageList, and than adding to it an image.

I'm getting the same exception.

any hellp will be greatly appreciated

Re: TreeView control

Where are you stuck? Do you have any specific problems?

It's pretty simple to do, dock the treeview on the left, dock a panel on the right. Subscribe to the AfterSelect event on the treeview and add the appropriate control to the panel on the right.

The ~ character is used as a wildcard in some cases.

Is the folder named "~WebApplication1" or "WebApplication1"? If it is the later, just remove the ~ character.

The folder is "WebApplication" only.The issue came while audit.I can't restrict them to enter ~ before directory.

Is there any way to handle this type of request(say in global.asax.cs file) so that we can get it done.

Thanks,
