A book called VB.NET Hacks & Pranks by Alexander Klimov explains sine waves pretty well. I do not know how to explain what he has wrote very well though. Sorry. This may or may not help, but this is a formula for the section on sine waves:

ptf(i).Y=CSng((cy/2)*(1-Math.Sin(i*cW*Math.PI/(cx-1))))

Play a sound while the app still runs

Hello

I want to play a sound/(audio file) (the format doesn't matter).
But I want to play the file and still use the application.
For example a button starts the sound/(audio file) and then if I press a new button, the first sound/(Adio file) stops and a new sound/(Audio file) starts.

It is almost the same as Windows Media Player, which plays the file and still make the app useable.

Can someone show me some articles or tell me how to do this?

Thanks
QzRz

You simply do the playing on a background thread. You can choose between BeginInvoke[^] and creating and running your own Thread.[^]

Persisting data in the app

How do I persist information in an app? I am taking some input from the user in a form and I want to access this information from any form. How do I do it?

I am talking about windows forms.

Thanks

You could use a config file for it. If the information is complex enough, you can use a database to store the data. The simplest way is to write a class, say Config, to store the configuration settings and then use XML serialization/deserialization to write and read back the data.

Yes, I thought of doing that. Is there no other alternative? I find it a little odd that there is no way I can persist some variables across the windows application in .Net.

This isn't necessarily a connection string problem. Check this[^] out for more info. If you google the error message you'll find lots of pages which talk about it.

You looked in your web.config?

This line:

ConfigurationSettings.AppSettings["MM_CONNECTION_STRING_GKAUser"]

says it gets it from there.

hi,

dont know how good is this method.i did like this last time

String tmp =Words;
do while(tmp.indexOf(" ")>0) // Do while you find two continuous spaces and remove those..
{
tmp = tmp.Replace(" "," ");
}
int TotalWords = tmp.Split(' ').Length;

Where there is a will,there is a way.

ClickOnce robust, reliable ?

I have been researching ClickOnce deployment, and I am very curious to hear from a few folks who have actually used it and deployed with it and had remote users updated with it, and, hopefully, someone who has used some of the advanced technical capacities offered in it such as scripting.

thanks, Bill

how do I convert a C# program into a windows installer? tips and advise would really really be of help.

or maybe there's a software i can use to change my C# program into an installer. Smile | :)

You should create a setup project for your application. Don't try to make your application install itself. Visual Studio has support for creating setup projects. There are many articles that show how to do it.

Hi all,
What is the best way to deal with the next problem:
I Have a ASP login page with codebehind C#
The user is allowed to login more then once on the same computer. But he is not allowed to login more than once on different computers.

should I keep record of it in a database with which ip address a user is logged in or are there other ways?

thanks in advance.
