This tip[^] I posted sometime ago disables it, but not permanently.

You could make the app run at start up (perhaps a service) so it is effectively permanently disabled.

I have small number of GUI attribute that i need to save in my application.
The attribute are simple ( windows size, window color, ext... ) and they need to be store in file ( can be XML or binary ).

I don't sure i know what is the fest and best way to write the code ?
Is it simple XML or serialization ?

Is there some example ?

Thanks.

You can serialize either as binary or as XML.
The advantage of XML is that is readable, the disadvantage is the size.

Our own CP holds these examples :
Binary : http://www.codeproject.com/KB/cs/objserial.aspx[^]
XML : Load and save objects to XML using serialization[^]
If you google, there must be millions of other examples.

Alternatively you could use the app.config and create a custom configuration section : Custom Configuration Sections for Lazy Coders[^]
That would keep all settings in one place.

Alternatively to xml serialization you can use the settings.

.NET framework required for the C# program

My C# program was developed by the Visual Studio 2005, and i have set the prerequisites to .NET framework 2.0, and i have tested to install it on a Clean windows 7 it has included .NET framework 3.5, and it seems my program is working, but how could i force it to use .NET framework 2.0?

And also, there is .NET framework 2.0 SP3, how could i include it and force the client to install it manually?

Thanks

Hi,

.NET 3.0 and .NET 3.5 consist of .NET 2.0 plus functional extensions, however they don't replace what was in .NET 2.0, they just add to it; therefore an app built against .NET 2.0 will normally run just fine on .NET 3.0/3.5

.NET 4.0 is different, it is independent of .NET 2.0, and offers a totally new set of libraries.

you shouldn't force a client to do anything.

what is your real concern about all this?

Since all of the .Net versions are merely extensions of prior versions, you don't have to wrorry about it. What you DO have to worry about is using framework objects/methods that become deprecated, because evetually, these objects/methods will be removed from .Net, and your app will refuse to work. What tis means is that you should probably update your tools to the newest versions, and rebuuild your app with the newest version of .Net.

Is this a WPF app? WPF uses URIs everywhere.

But anyways, somewhere you are specifying a URI in the wrong format. Or the control is. Did you try turn on all first chance exceptions? That might help you catch it when its really happening.

Thanks for the reply. It turns out it was getting into an unexpected part of the code after the Invoke (), so I have to dig deeper.

when you want to close the thread, rather than remove the question and leave a messy thread, I would suggest you just append "[solved]" or "[closed]" to its subject line.

An insert statement. Beyond that, I can't help as this is far too vague. We don't know what database, what version of the .NET runtime, etc, that you are using. One thing though - ensure it's not open to a SQL Injection attack.

If it's an asmx file, then it should be a web service, so you would write a WebMethod in there. Have a read up on traditional web services in .NET to see what you need to do.

like this?:

{

string sql = " insert into FX_Forecast2 (Symbol,A) values( '"+s+"','"+d+"')";

OpenDb();

cmd = new SqlCommand(sql, con);
cmd.ExecuteNonQuery();

con.Close();

}

do with writing this code and loading this url(http://aaaa.com/Default.asmx/zakhire?Symbol=+S+&A=+d;) these value will insert in database?

how can i run this url for test in visual studio?(not in mql4)
