It's not LIKE a javascript alert, a javascript alert is your only option in ASP.NET.

Well, step one is to fix the code so you don't get the parsing error. If you told us the actual error message and gave us the code you're using, perhaps we could help more.

That's a new one. Most people too lazy to do their own work, say their question is urgent.

Read the article I link to in my sig. Then, break down your task into steps and work out how to do them, asking questions here when you get stuck.

OR, contact your rentacoder client and tell them you're not really a programmer at all, and offer to return their money.

No. You can just use p/invoke to call methods on your object, and you can define structs that mirror any structs used in the C++ code Check out www.pinvoke.net for lots of examples, which are all using Win32 APIs

Member 2503963 wrote:

Use the wizard to create a dll, import your C++ code into it ( so, it's a C++ COM dll ), and then provide a COM interface to yuor methods.

Have you read the documentation? The Hastable class has a ContainsKey[^] method that is used to detect the presence of a particular key.

BTW, unless you are still working with .NET 1.x, you are better off using the generic Dictionary[^] class instead of a Hashtable. The generic Dictionary class allows you to specify exactly what data types the key and value should be, thus enforcing type safety in your data.

Well, this is a pretty top level question. First of all, do you have a clear spec of the features you want. For example, do you want to support threaded messages ?

Then, you need to work out what skills you need - do you know how to use ASP.NET ? Do you know how to use SQL Server, or whatever DB you will use ?

You can use the built in login control, but I prefer to write my own, you just store a value in the session to tell you that a user is logged in, and check that value from a base class, to redirect people who are not.

The rest is pretty simple, you just need to work out a database format for messages, and the UI to display them.

you have to run this execute file with specific switch(-i)
so write below code in command prompt to install asp.net 2.0

Does Ctrl+F5 work?
Did you try to create a new web-site? Does it work ok? Had you change something in sytem services? try to delete web.config and run you web site again. does windows appclication (windows.forms) debugging work?

Hi There

Ctrl+F5 not working at all but i notice something yesterday .

When i press wether F5 of ctrl+F5 a notify icon appears near the clock "ASP.NET Development Server" Port 3444 for example but in the web browser the address is http://localhost:3441/Default.aspx

do you notice the change in ports number and if i change it manually it works . I don't know what is the cause of this change . Everytime the different between ports number is exactly tow of three digits .

This problem is happening with any Visual Studio 2005 website i do but with VS 2008 everything works so fine .

Thanks.
