Hi all,
I have a vc++.net application that draws a graph at runtime after a certain time interval.My prob is that while the graph is being drawn on the GUI,if I open another window or any message box comes over the GUI,that particular area of the graph gets erased and is not redrawn.
Please help me.I am a beginner in vc++.net.
Any help or suggestion is welcome.
Thanks,
Jyoti

How?

Are you also a beginner in communications? Think about what you are doing here using this forum. You are asking people to freely use their time to help you. At the very least you should make an effort to communicate your problem clearly, completely and succinctly.

So based on that one could guess that you do the drawing in a timer event handler. Drawing needs to be done in response to Draw events or WM_PAINT messages, not timer events. Also a Picture control can be used. The Picture control would then do the drawing in response to the Draw events. To use a Picture control you would create an Image and draw into the image then assign the image to the Picture control.
good luck

His reply was reasonable. Your question was impossible to answer, that's why you got no replies. Take his advice and try asking in a way that gives people the info they need to help you.

Yes I accept that.But I am not complaining that I didnt get any replies but the reply that I got was rude.Thats all I am saying.The reply cud ve been better and polite.
I do agree my question had very little information on which ppl could base their replies.
Rudeness is the fact I was upset about.
Anyways I will try to post it with more details.

Did you even read my post? What do you call this quote from my post if it is not an attempt to help?

Here's a tip. Don't smoke crack when you are posting requests for help in internet forums.
Here's another tip. Tell me to be quiet one more time if you want to see what rude really looks like.

Yes I did read your post.But you had already done the harm.
First you write rude words.then you attempt to erase it by trying to write some help.But one wont forget wht u did initially.
Even after telling you not to reply to my post,you ve stl done tht.....
I can understand that your quarrel with whomsoever is stl not over.So I can see you fuming with my reply....hota hai....
May be you know the highest peak of being rude to someone.....May be you ve been brought up tht way.....but I dnt give importance to ppl who dnt knw to speak politely.I cant wait n advice them whoever behaves tht way.I ve more imp work to do.
Now even if you post anything I am not going to get it.Because I knw how to prevent it.
Good luck for your future.Hope you keep quiet this time

It's always amusing when somebody attempts to make an argument out of nothing and then gets seriously, seriously pissed off when somebody points out that they are being arsehalfs.

Well my day just went from bad to worse when I received requirements from a business person stating there are 4 valid values for gender:
male
female
unisex male
unisex female
Now I'm no rocket surgeon but I'm pretty sure that business person couldn't find their ass with both hands and a flashlight. I guess having a Business Degree means you are an expert at sticking your nose in business that you don't know anything about because, well, apparently you don't know anything. In fact how did they keep breathing long enough to even have that excellent moment? I guess they're just one of natures marvels, like hurricane katrina, I big blustery wind that leaves a trail of destruction in it's wake.

I guess I will have to finally migrate to .NET 3.5 so I can use Lambda Expressions, they solve everything you know! Maybe I can finally get rid of my left handed bolt stretcher.

Surely unisex male and unisex female are effectively the same - they are hermaphrodites. Anyway, everybody knows the three values for sex; male, female and nowhere near enough.

I have recently moved to VS 2008 to code with but am having an issue. The
"asp:..." tags won't list in intellisense and give me the following error:
EXAMPLE:Validation (): Element 'scriptmanager' is not supported
The funny thing is that the code compiles and runs without any errors, even with the green underline under the tag name. I have loaded VS90sp1-KB945140-ENU to get the use of SilverLight into some testing. What could be wrong or missing from the web.config file that is causing intellisense and the apsx file to lose the ability to see these and user control tags. This problem didn't exist until I ran through this upgrade.
Thanks for your assistance,

Does anyone know what IoC container works in Medium Trust?

A simple CP search would have turned up this[^] one.

Thanks Pete
but it doesn't say anywhere that it works in Medium Trust (I'll test it)
Does anyone know if one of these work in Medium Trust
Windsor, Ninject, StructureMap (I know Unity works)

The closest thread I found to my question was http://www.codeproject.com/script/Forums/View.aspx?fid=1649&msg=2149266[^].
I'm looking to have a thread send an update to a status indicator control. Because the control (and the form hosting it) will be on a different thread, it's necessary to perform the update via control.invoke. If window displaying the control is disposed, it would be perfectly acceptable for the call to simply do nothing.
Presently, I'm using a static Boolean field called 'tryingInvoke' which is set to True immediately before the invoke and to False as the first step of the invoked procedure. Only one thread will be attempting to perform the invocation, so that shouldn't introduce any thread-safety issues. The invoke() call is surrounded by a try block which includes
Catch ex As ObjectDisposedException When tryingInvoke
That seems to catch the ObjectDisposedException in case the object gets disposed between the invoke attempt and the actual invocation, but it seems rather clunky and it doesn't avoid a first-chance exception. Delaying the form close while making repeated calls to Application.DoEvents (suggested in the other thread) might be workable, but I would think that having a control calling DoEvents would be a Bad Thing.
Are there any better approaches?

Sure but it's the second clunk, which is required due the first clunk. The first clunk was a design that allows an object to be disposed while another object has a reference to it. In a garbage collected environment that's not supposed to happen. It probably takes the violation of one or more principles/best-practices to accomplish that loud of a clunk.
