Lookup the System.Diagnostics.Process class in MSDN, should give you the info you need.

No matter what I've tried, calling CreateControl() on a form or ctrl, does not force the creation of a handle, as the docs say. The only thing I found that does, is the usual Show() (or ShowDialog) method. The problem is, I need to modify some things before the form becomes visible, which are not callable until a handle is created (understandably).
Could someone please prove Microsoft right, and make me eat my words? Or at least verify my findings?
Cheers

Hello,
I am trying to do an image editing app.
It requires opening and displaying an image and then selecting a portion of the image for crop. I also want to rotate the image.
(1)How will I implement "area selection" [click and drag to mark an area] for an image ?
(2)Which will be the best control to display the image, for edit operations?
Thanks,
Tweety
It's easy to sit there and say you'd like to have more money. And I guess that's what I like about it. It's easy. Just sitting there, rocking back and forth, wanting that money.

Draw the image, store the co-ordinates you've dragged, and draw them onto the window ( not onto the image ), so they are lost with every refresh and do not affect the image.

Just whack it right onto your window.

Hey, at least Logo had, at it's inception, a mechanical turtle. VB has always lacked even that... - Shog9 04-09-2002
Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

Thanks CG for the help.

Isn't there any image control that will scroll and show the original image ?

Does anyone know of a sscanf (Old C-runtime function) equivalent in C#?

Use the System.Convert class. There's a bunch of stuff in there that will let you convert from one data type to another.
I don't know whether it's just the light but I swear the database server gives me dirty looks everytime I wander past.

As David said you can use the Convert class however sscanf provided more of a parsing technique than what you will probably find with Convert. You may wish to look into the RegEx (regular expressions) class as that's where the power will come from (;P). Here is a quick article to read up on if you are new to regular expressions.

Forgive me for not brushing up on my C libraries.;P

I'll look at RegEx. The parsing is what I am looking for. I've looked at Convert. Maybe a combination of both ?? Basically, I'm parsing comma delimited data (text, numeric, date, etc.).
Thanks for the suggestions.

Roy

Hello,
I wrote a program who is not UI dependent. I have all my program logic in a class and I raise some events for any potential frontend.
I can then create a console application or a Windows form application using the same program logic.
The frontend just run a thread using the run() function of my main class (UI independent) which do all the job.
This main class also creates internally several threads performing various tasks in parallel. Since all this threads are just pure computation I have no problems.
But I recently wanted to create forms in some of these internal threads running in parallel and I have been unsuccessful for far 
What happens is that forms get created but are not responsive at all and the internal threads get stuck. How can I create these forms and make them run independently in each thread ?
Here is schema:
Frontend (Console or Form, main thread)

Main class (running in a thread)

Child threads (computation)
x x x x x <-- child threads can not work with forms
x x x x x <-- how to call functions in those forms ?
Child threads forms
Any idea ?

Hello,
I understood I have to use invoke from threads to call methods in controls.
But what about creating forms from threads ?

Hi,
My goal is to have several forms running independently. Each form has its own thread doing a specific computation.
One example could be to have several forms embedding the webbrowser control and automatically crawling a different website. All will run in parrallel.
Any idea ?

Hello,
I would like to know if it is possible to use the webbrowser control just to navigate a webpage and then traverse its DOM, without creating a form and even in a console application ?
Thanks,

Lookup a sample called WalkAll in MSDN.

Hello Stephane,
Ok but WalkAll uses only the MSHTML component. I'm trying to use the WebBrowser control because it adds a lot of navigation stuff I would like not to take care of.
Thanks,
