Hi there!
I have a problem. What i want to do, is opening a remote file on the internet (a xml file) for reading in my application. The remotehost is not running any serving functions, the file is just available on the internet.
Is there anyone who knows how to do this?
Thanks in advance!

I wrote an article regarding this issue. The only major drawback is that this method doesn't function in all windows versions...

Erhm. Thanks for taking the time to reply to the topic, but that was a link to a article regarding "ExtendingFileDialogs"

You can use the HttpRequest class to request the file.

If I open the openFileDialog, usually I must select the view to "Details" manually. How can I automate that ?

I'm making use of a datagrid, How do you get the current value of a specific cell (row 0, col 0) after the user sorts by clicking on the columnheader? This is what I tried using the MouseUp event but I seem to be getting the value of the cell before the sort.
private void dGrdFamily_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
//if left mouse is clicked
if(e.Button == MouseButtons.Left)
{
Point pt = new Point(e.X, e.Y);
DataGrid.HitTestInfo hti = this.dGrdFamily.HitTest(pt);
if(hti.Type == DataGrid.HitTestType.ColumnHeader)
{
this.textBox2.Text = this.dGrdFamily[0,0].ToString();
}
}
}

If the DataSource is a DataTable you can use
private DataRow GetDataRowAt(int index)
{
DataRow dataRow = null;
CurrencyManager currencyManager = null;
currencyManager = (CurrencyManager)this.BindingContext[this.dataTable];
if ( currencyManager != null )
{
dataRow = ((DataRowView)currencyManager.List[index]).Row;
}
return dataRow;
}

Hi:
Thanks for your help. I tried your suggestion but I came across the same problem. It seems like the MouseUp event that I'm using may not be the best event to use in this case. It seems like it is obtaining the row value prior to the actual sort of the datagrid values.
Do you know of any event that I can implement to notify me when a change has occurred in a cell/row value (not change in row index)??

Use the datagrid.Refresh() function...

hi to all,
witch reference do i have to add to see the flexgrid and hierarcical flexgrid control in my toolbox
best regards and thanks in advance

Flexgrid last shipped with Visual Studio 6 (old school). It doesn't ship with VS.NET (same deal for heirarchical flexgrid, I think). If you want to write apps with it you have to fork out for the license for VS6, install the old VS on your dev machine with VS.NET and access the controls using interop.
I miss it too. So lightweight. So easy to code against...

i want to add a dll which have two function one is for reading data from the parallel port and one is for writing data to parallel port using c#.
how i will use this dll and call its function please tell me.......
|

open a new project
select class
type in your code
make sure the functions are public class
bulid ths solution
save the project
close the project
open your project
use the Using to call the dll
like
using projectdll;
create a reference type like
project.Adddate mydate=new project.adddate
you can now use the instatiated object
mydate.adding(rttr,teert);
if it returns a string
declear a string reference type
s=mydate.adding(rttr,teert);

Hi all !
I have build a remoting server as a simple application using a WinForm to show messages.
The WinForm program starts a serverprogram, that registers a RemotableObject to be run in singleCall mode. The Server has an event (taking a string var) which the WinForm registers a method to, so that a RichTextBox in the WinForm will show any text from the stringvar on the event.
The RemotableObject on its side, has a static event which the server (abovementioned) registrs a method (on itself) to, just delegating the incomming event (from the remotableObject) on to the WinForm by firing its own even, thus sending the incomming text to the Winforms registered medthod.
That is: every time anything interesting happens on the remotableObject it fires the event, which the server has registered to - and receiving the text from the remotable object the server "sends" it to the WinForm (by firing its own event, which the WinForm has registered to) thus displaying the text from the remotable object in its RichTextBox control.
If I run some program, using the remotableObjects methods, everything works fine the first couple of times, but then the WinForm program crashes with a NullPointer error (actually the debugger traces this to happen just after the Application.Run statement starting the WinForm)
If then I replace the RichTextBox display with a Console.Writeline of the exact same text (at the exact same place, as the winform displays the text in the RichTextBox) I can go on and on without any errors, getting everything displayed in the console output.
Any ideas about why the RichTextBox causes the crashing ???
TIA

Hi!
Unspecific crashes/exceptions often occur because of threading problems.
Could it be that you're updating the RichTextBox from a different thread that it was created on?
Try using Invoke or BeginInvoke to call a delegate for setting the text and see if your app still crashes.
Regards,
mav

Thanx mav.
Considered that, and must admit that treading is not exactly my strong side (a bit new to .NET)
I will try to follow your sugestion, but it still puzzles me that everything is started from the server WinFom and also that the replacing of the RichTextBox with the Console.Writeline trick, makes the code work.
But then again, I guess that the remote-call (from some client-app) to the remotable object makes the whole scenario a bit more complex in terms of thredaing, so although the serverproces and the WinForm runs in the same thread (the one started by the other, that is) I couldn't really tell which thread holds the actual invocation of the remotable ???
Coming to to think of this, actually makes it a lot more complicated, than at the first glance ?
Could you (or anyne else) perhaps lead me to some source of understanding this issue better ?
TIA

Hi all !
Found the solution - it's just like mav said: use a delegate.
For further information read this article which explains everything nicely: http://www.codeproject.com/csharp/remotinggui.asp

Why would you do the following rather than writting this code without the try block?
<br />
try<br />
{<br />
}<br />
catch(Exception excep)<br />
{<br />
throw;<br />
}<br />
This is in a utility function so the idea is to handle the exception in the code that calls this function. Why would you write a try catch here instead of just letting the code throw the exception?
Example: here[^]
// TODO: Write code.
