Hello everybody,
I want to connect a computer on one LAN to a computer on another LAN using a modem and a phone line (a HyperTerminal sort of thing).
I want to be able to dial a number from a list and send and receive messages and files, preferably with acknowledgement.
I also want the whole stuff in c# (v2003) using Windows Forms (GUI), not the console type.
Can anyone of you help me out with this or point me to a link where it might be available.
Thanks a lot.

There are several ways to do it.
-> Draw a circle (with fill) and a Rectangle(with fill same color as background) over it (covering half the circle).
-> Look into FillPath and FillPie methods of the graphics object MSDN.
hope this helps...

Hello,
In my application (net2.0) I have a few threads. I want to stop the threads when the main form is closed. Now I'm not sure what I have to do.
Normally I would implement a IDisposable interface. In the form exists this function already and it is not virtual.
What is the best way to implement this? Which event I should use?
Regards

Hi
When you create your threads, set the IsBackground property to true.
When you close the app, the background threads are automatically terminated.

Hello,
Try to use FormClosing event (.net 2.0) of the form.

I have a datagrid, user can choose which cols will printed. Ex : User choose 5 cols, the report will have 5 cols. How to do that in crystal report.
Regards.

If I'm not mistaken you have two ways of using Crystal Reports, Push and Pull, One of them can attach Datasets, making the reports more or less dynamic. Crystal Reports isn't really 'dynamic' as anyone would want it yet. Let's hope in the next version they will integrate it a little more with .net ways  .
What you can do, with a little meddling is doing it via passing parameters to the report. I'm not sure what you'd like to do, but to make the reports dynamic we used to ask the parameters in our application. The application would than pass them to the report.
hope this helps

Crystal Reports is not very useful when it comes to these things. It is an absolutely terrible tool when it comes to doing normal things. I have several times had to create my own reports using print objects/GDI+ etc because CR wouldnt do what I wanted it to, or it was just easier and quicker to do it myself. Setting parameters may be an answer.... Just let the users enter what coulumns they want, then use function fields to match their input up to actual columns. Unfortunately, you still dont have a way to layout the page dynamically. It may turn out to be quicker to do your own reports lol. Hopefully CR will be completely redone in its next release.

Hello,
For importing function i use
[DllImport(DLLNAME)]<br />
public static extern int function(Type Args);<br />
into my class. and it's working fine.
But for import variable which is exported by dll this method doesn't work.
It will get error that "DllImport is not use for this item only use for method import". And for extern keyword say that this will not use for this item.
Plz help me.

Create a function that will expose that variable's address, then you can write to it.

I created a local web proxy server running on my PDA in order to browsing web pages locally without network connection.
I must tick "This Network uses a proxy server to connect to the Internet" and set up the "Proxy Server" in Settings/My Work Network on the PDA. after that, My local web proxy server can receive the request from Pocket IE.
However, after that, the Web Services Request (HTTP+SOAP) sent by calling the web services from my local web server (I created) will be directed into my local proxy server but not go to the requested remote server.
I have tried to use some methods such as GetEmptyWebProxy.. but they didn't work..
Does anyone know HOW to solve this problem
thanks

This might not be relevant, but I have never been able to get WebServices working via my local proxy (FreeProxy).

Did you properly assign that to the generated webservice class?

I'm using DataView to sort my dataset. Once a user sorts the data I want to reset it back to show all records. Whats the right way to do this? I'm using the RowFilter property to sort the dataview.

Hello,
You can set DataView.RowFilter property to string.Empty to view all records in the table.
RowFilter property is used to filter the records. You can using Sort property of DataView to sort the data.
