this is the code :
if(dsOrdersDetiles1.HasChanges()==true)
{
AdOrdersDetiles.Update(dsOrdersDetiles1.Tables[0]); //only the data in the grid is update but i need the OrderId to be update in the same row .
}

Hi
I try to delete my Temporary Internet Files using C# Code.
I thought.. no problem, but the only file that was found is the desktop.ini...
No other files in that Directory..
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
<br />
string dir= Environment.GetFolderPath(Environment.SpecialFolder.InternetCache);<br />
<br />
foreach (string fileName in Directory.GetFiles(dir))<br />
{<br />
File.Delete(fileName);<br />
}<br />
}<br />

Under what user account are you running the code? Each user account have their own cache folder for Internet Explorer.
---
b { font-weight: normal; }
|
|
|
|
|
Hi
It's an account where the User is in the administrator group.
|
|
|
|
|
Are you sure? Check the contents of the Environment.UserName property.

b { font-weight: normal; }

Have you looked under C:\WINDOWS\TEMP\Temporary Internet files?

Hello everybody...
I have a TCP/IP client/server chat application.I want to add voice chat feature to my application.What is the start point ?
How can I implement this feature in c# ? How can I implement audio streaming in c# ? Please guide me.
Note : My application works on LAN and is not on internet.
Best Regards,
XironiX

First you have to capture the audio. Try search 'audio capture' here on CP and you'll find many interesting articles.
Then you have to design some application protocol to compress and encapsulate audio data and stream it to the other host, maybe adding silence-suppression algorthms.
There are many mpeg libraries on the net, you should choose one simple to use.
Trust me, this is not simple at all.

Thanx for your answer...
Did you heared anything about Microsoft Media Service. Do you know that can I use Media Player SDK to do streaming ?

Well, I don't know what the problem is...
Search MSDN for Bitmap class and have a look at its methods...

Is there anyway to get or reference the local directory a web service is located in ?
i.e. similar to Application.StartupPath ?
|
|
|
|
|
A web service is a variant of an ASP.NET weg application. It doesn't "come alive" until it's called by some consumer and instantiated. There is no "StartupPath".. You could look into using Server.MapPath(), but web services are not my strong suit.

Right, I need to get the local path reference within the service during runtime, so I'm not worried about it not being instantiated. I'll look into MapPath(), thanks.
|
|
|
|
|
Well it appears the Server.GetPath() method is useful from a client perspective, but I need to get the local path in the service. Any other suggestions ?
|
|
|
|
|
I was wrong...just had to pass null as the path...thanks Dave.

 Can a windows service capture HID input events?
I need to capture HID input from a remote control. I have done this and was successful in a windows application by overriding WndProc.
I need to be able to do this in a service and can't seem to get anything? Does a service have a hidden top level window I can override? Is there a way to do this?

Hey,
i am trying to develop a small program taking advantage of .NET Remoting.
I have a button which i want to Start and Stop the Server with.
But my problem is that I cant really find any information about how to stop the Server.
I simply start the Server by doing the following:
RemotingConfiguration.Configure("theconfiguration.config");
But then i dont know how to stop the Server again when pushing the button.
Can anyone help me ?
I can see that if i instead of using a configuration file, set it all up directly in the code there is the ChannelServices.RegisterChannel and the ChannelServices.UnregisterChannel.
But will this be the correct way to do it if i want to start and stop the Server ?
Or will i have to etc. make a new application domain and run the server there and then destroy it when i want the Server to stop ?
How should it be done ?
Hope someone can help me
Best regards
Martin

I am trying to sort out the difference between these terms as they seem to be thrown around interchangebly. But indeed are they really different concepts or is casting basically helpful in describing boxing/unboxing?
Casting defined: objects of one type converted to objects of another type
Boxing defined: 1 - casting a value type into a reference type 2 - casting to an object
Unboxing: casting the reference type back into a value type
And sort of a separate question, but how can I figure out the rules of casting.... in other words I expected to able to do this. Is the reason it cannot be done because the variable i2 is not an object?
int i2 = 5;
string s2 = "";
s2 = (string)i2;
However you can do this, and myShort is not an object.
short myShort;
int myInt = 500;
myShort = (short)myInt;
So I am a bit confused about when I can try to cast vs box!
