Invalidate() forces a paint event. Which calls onPaint. Which, in your code, calls Invalidate.
You have no need to call invalidate in your paint event, the form is already invalidated, hence the fact that your paint code is running.

I need the OnPaint event to call repeatedely, over and over. That's why I put Invalidate() at the end of the OnPaint event. Is there another way to do this without the screen flashing?

Use a timer event to periodically invalidate the form. If you can call the overloaded version of Invalidate that takes a Rectangle to invalidate only the portion of the form that needs repainting, you'll get more efficient results. Invalidate() causes the entire surface of the form to be repainted.

What is an example of a timer event?

For a form, you could create a System.Windows.Forms.Timer[^] object. Hook up to its Tick event, set the Interval property to the desired polling time, start the timer, and finally in response to the Tick events, invalidate whatever portion of the form that needs to be repainted.

How is it going? I see you still haven't managed to get Visual Studio Express yet. I have to commend you on your persistence to develop without Visual Studio. You are learning a heck of a lot of good stuff that a lot of people would just walk past because Visual Studio does it all for them. Not enough people, in my opinion, take the time to learn what is actually going on. You are and that is great! It will mean that in the future when things go wrong you'll be able to think your way out of the situation much better than those people who learned while Visual Studio was hand holding them through everything.

Hello everyone,
I was wondering if it is possible to change the SOUND when the DilagoBox pops up. Currently the sound that I am getting sounds like "DOMB". Is it possible to have something more elegent or customized?
Thank you very much and have a great day.

You mean message box. The sound is linked to the sounds set up in the user's preference. You can change the messagebox's icon, which also changes the sound it makes. See the various overloads of MessageBox.Show[^]
If you want something completely different then you will have to write a (real) dialog box of your own.

Hi,
I am trying to make this work here, I set a form authentication on my site from a SQLDatabase. Now the membership tool did not seem to give me all I needed so I followed an example using tickets to specify user roles from the database. All in all it works well. The only problem I am having is that whenever I am authenticated with a lesser user role (let say Role 1) and I am trying to axs a page requiring Role 2 let's say, I am redirected to the login page - not the error page. I tried to find a trick to redirect to the error page all users already authenticated (meaning that most of the time it would be because they tried to axs a page to which they can't axs) but that means even if the user wants to go back to the login page he will be redirected to the error page, which doesn't make sense.
So my question is - Is there a variable or a way to know that a user tried to axs a restricted page even though he was already authenticated??

PS: I hope it's clear, I seem to have difficulties putting it to words

If you want to redirect the user to error page, then raise a custom exception. And configure your web config file customError section to redirect to the required page.
Hope this gives you some insight of the solution am thinking of

I had thought of that but I couldn't find out where and how to raise the exception. In my mind the embedded role from <authorization> element already raises an exception to send to the login page...
So I guess I found a workaround - probably if I put the error page as my login page in the webconfig and then redirect if not autenticated it would work. Although I find it a bit sloppy and I cannot beleive there isn't a better way to do this ...
but thanks for the input

You are in the wrong forum, you need to be posting this in mobile development forum.
With a subject line like that, most of the people are going to ignore your post. Give a meaningful subject to get answers to your post.

hi
i want to add any exe file(s) to my app and extract it at on Hard drive at runTime ?
thanks

You can embed any binary data as a resource in the project. However, I am suspicious of a request to hide any executable code inside another assemby. It seems to me to be the first step on the road to creating a Trojan.

no..no..no
i don't want to create trojan,virus,spyware or ...
i want to protect my exe file(s), that's right

And how is embedding it in another exe going to protect it?

Hello everyone,
I have a ContextMenu in my Windows Application with FOUR of options. I was wondering how I can add a check mark to the left of the options in order to show the user which one has been selected?
Thank you very much for your help and have a great day.

The MenuItem in the Context Menu has a Checked property. Set it to true.
