Thanks for your reply.
It turns out that the problem was related to two different sets of similar classes.
The code was using some objects from one set of classes and some from the other.
The generated proxy code was all messed up thus confusing the client.
Once we removed the duplicate (proof of concept) set of classes everything worked as expected.

Hello,
I'm having a trouble with the 2.0 Framework method FTP.ListDirectory.
I'm writing an application which creates a file by executing an http command, then verify if the file exists on the server and downloads it. The problem is that the list of files returned by Ftp.ListDirectory doesn't change even if the file is created(I can see it with a graphical FTP client).
Sometimes it works and I get the list of all files. But it seems to me if I make many consecutive requests, the files list isn't refreshed any more as if it was stored in a cache....
Can you help me to fix it?
Thanks.

Are these files hidden or system files?

Hi,
thanks for replying.
The directory listed by the code has only .zip files. I even can see them in my graphical FTP client. So my answer is no, files aren't hidden.

Hi,
I think the I have the answer to this post. I'm not really sure but so far I've done many consecutive tests and the results of the response always changes if new files are created.
It's about the cache policy and this is the way to set it.
System.Net.FtpWebRequest request = (FtpWebRequest)FtpWebRequest.Create(param);
request.CachePolicy = new System.Net.Cache.RequestCachePolicy =(System.Net.Cache.RequestCacheLevel.NoCacheNoStore);

Have you considered:
treeview.ImageList
treeview.StateImageList
treeNode.ImageIndex
treeNode.SelectedImageIndex
treeNode.StateImageIndex

hi
i have a problem , with a picturebox
i set the path of the image proberty of picturebox
how can i get this path from picturebox
thnx 4 help

Hi,
if you got the picture loaded by calling the Load() method, or by setting
the ImageLocation property, then you can get the image path by getting
the ImageLocation property.
if you got the picturebox showing an arbitrary image, the picturebox can not
possibly tell you were on disk the image is stored (it does not even have to
be on disk, it could well be a synthetic image).

Hi,
In my windows application I need to display MonthCalendar control with some selected dates/BoldedDates.
I am using the property "Bolded Dates" to add selected/some dates. But those dates are displayed in "BOLD".
But I need to display with different background color (like selected).
How can I display the "Bolded Dates" in different Background color?
Thank you
Ramesh

Maybe the control does not support that. What does the documentation say? Is there an "owner draw" feature?
|
|
|
|

Hi,
Thank you for the reply,
I gone through the MSDN 2003 about the MontheCalendar control there is no OnOwnerDraw method.
Is there any other control that can Matches my needs?
Thank you.

Can anybody shed some light. I'm a bit confused. Still a noob at C#. I read that Global variables are not supported in C# yet it seems to work for. They recommend you use struct instead but I can't seem to get it to work for me. I'm having a hard time understanding to program a string that can be accessed by any function without having to pass the String contents to the function. Basiccaly I need to access some strings globally. Any suggestions?

Make the strings static members of a class (eg: StringHolder) and refer to them from any class in the following manner:
public class StringHolder
{
public static readonly string SomeString = "hello";
}
public class ReferringClass
{
void someMethod()
{
string foo = StringHolder.SomeString.Reverse();
}/ravi

There are global variables in C#.
Just create them outside the functions.
For instance:
public class Circle
{
double radius = 0.0;
double pi = 3.14;
public Circle(double Radius)
{
radius = Radius;
}
public double Area()
{
return pi*Math.Pow(radius, 2);
}
}
Best regards!

They are not global. They are members of the class.

Yes I know that works. I been programming that way all along but I just upgraded to Vista and downloaded the latest C# version. One of the note I read claimed it does not support it so I'm weary programming that way in xase it sops working in the future.

Hi,
I am very new to c#. I have created a com object in c# and am using it from vba. it is working fine since until now i only needed to pass variables from vba to c#. I would like to pass a function pointer so that c# can callback a function in vba. any idea if this is possible?
thanks

Hello All,
I need a guidance on following:
1. I want to crate a windows application with Form or dialog the application behaviour is such that,
it shows a dialog or Form to user and simultaneously,
2. it process the data by listening to seria port and notifies on the form if a specific data is received.
(I know how to implement in VC6)
3. when I open a VC#.Net application wizard it gives me a form class , but I am not able to find the place where to add a code for serial port because the form is run by application thread and is blocked once the Application.Run is called.
4. To simplyft points above , I want to change the text of a form text box after the form is displayed.
Please see the below code for clarity:
namespace WeighbridgeManager
{
static class WeighbridgeManager
{
///
/// The main entry point for the application.
///
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
My Form WBScreen = new MyForm();
Application.Run(WBScreen);
//WBScreen.txtSomeTextBox.Text = "Hello World!!!";
}
}
}
The commented code never executes, I guess I am missing some threading logic here.
Thanks.
To simplyfy the problem, take it this way.
I want to change the text in the Form commented part and where to place this text.

Think of the Application.Run() command as starting a loop that continuously looks for updates and messages from inside the form that it is running. Any code after the .Run() will not execute until you close the form that is open.
Thus, you must put code that you want implemented INSIDE of the the form that you created. So inside your WBScreen class, on your Form_Load (or constructor, or whenever you want it executed), place the code that you want to run.

Hi,
To add to what Phil told you, a Form normally is "event driven"; everything
it does, is triggered by some signal that causes it to execute a "handler".
Examples:
when the form is first loaded (so it can become visible), it executes a Load event;
if you add an appropriate OnLoad(...) method, that will run then (just once).
when you add a Forms.Timer that will cause a particular method to be called
periodically
when you add a SerialPort in your form's constructor, that SerialPort has a
DataReceived event, that could call one of your methods every time a specified
amount of data has been received.
A lot of the words in the above are keywords or even class/method names;
look them up on MSDN to get all the details.
I strongly suggest you get acquainted with Forms, Buttons, events and the like long
before you start working with the SerialPort class !

Hello Phil,Luc,
Thankyou very much for the guidance.
I did a brief study of what you sugested, article (http://www.codeproject.com/csharp/workerthread.asp ) states what you described.
I am coming up following approach mainly based on the link I have given above:
1. Create a worker thread in the form class which will liten to serial port.
2. Keep on apending the serial port data as and when received by a deligate to form.
3. To get the text of a form's control, Call a deligate in worker thread which will return string by calling a function in form class to get the control's text.
Please suggest.
Thanks and Regards.
Amarjeet.

Sounds good to me, with one comment:
"3. To get the text of a form's control, Call a deligate in worker thread which
will return string by calling a function in form class to get the control's text."
You could do the append logic in the delegate (and hence in the form class) itself,
so to the worker thread it would mean: "here is new data, deal with it",
and to form would take it to mean "I have got new data, I should append it to
the previous data and update the GUI".
Warning: the packets in which you will get data will be arbitrary, not necessarily
entire lines of text, or entire units of whatever data structure they represent.
