You need to explicitly add a reference to System.Runtime.Remoting.dll. VS 2005 automatically adds reference to System.dll and certain other dlls depending on the project type, that's why you might not have done that before.

hi everyone,
i'm developing 2 applications that can communicate to each other. application1 is using a tcp socket to send a message to application2. application2 should receive the message through its webservice. now, my problem is i'm not getting the message in application2. i tried running ethereal to check the packets and i can see that the message is going to the computer where application2 is running but i'm getting a Null reference exception on application2. i tried using stacktrace
but it's only giving me the line where the null reference occured no further information. so, i need advise what's going on. why am i not getting the message from the application? i have been working on this problem for a week now. so, please advice.
thanks.

Near to impossible to answer from your description. Please post the relevant receiver code and probably also the sending code (and don't forget to mark the line where the exception occurs).

hi,
thanks for your reply. i didn't post the code since it's very long. basically i only used BeginSend()(tcp socket) method to send the message and i get to this part of the other application :
//------WebService file--------
public string EndSendMessage(System.IAsyncResult asyncResult) {
object[] results = this.EndInvoke(asyncResult);
return ((string)(results[0]));
}
//---Form.cs file---------
MyWebService ws = new MyWebService();
//other code here...
string str = ws.EndSendMessage(); //<---- string is null
I've been looking around for a code that works like this but i can't find one. Is it really possible to send a message from a TCP socket to a Webservice?
Thanks.

Hi
I have two form, a main form with a button, its text is Show. When click this button, it shows me the second form and the main form is hidden. The second form with a button, text is Show Main. When click it, the main form is shown. But I cannot do this.
Please help me!
Thanks!

How are you showing the second form? If you're using ShowDialog , then the second form is modal, so you can't show the first form when it is visible. You might want to use Show instead.

Using Vs2005, I cant get my custom paint to work during designtime.
Heres the example:
Start a new windows app.
Add a user control
Paste the following into the usercontrol code:
protected override void OnPaintBackground(PaintEventArgs e)<br />
{<br />
base.OnPaintBackground(e);<br />
<br />
Graphics gx = e.Graphics;<br />
Pen pen = new Pen(Color.Red);<br />
Rectangle rect = e.ClipRectangle;<br />
rect.X += 10;<br />
rect.Y += 10;<br />
rect.Width -= 20;<br />
rect.Height -= 20;<br />
<br />
gx.DrawRectangle(pen, rect);<br />
}
Build the project.
Ok, basically, I only see my custom paint if I drag my control into a form.
If I just want to look at the customcontrol designer screen, I dont see my custom paint.
Am I missing something? Am i supposed to set a flag somewhere, like Ownerdrawn?
Any ideas why?

That's normal. In design mode of a user control only the InitializeComponent function is executed - nothing else.

I have retrieved the data and it appears in my list box, but I do not know how to have the data listed in columns instead of horizontally. Can you advise me on this.
Thanks.

Do you mean List View? Because as far as I know the List Box control doesn't support columns.

I am having an issue with a loop. Basically what i'm wanting to do is copy the first path in listView1 then automatically move on to the next item on the listView1. I did some testing without the file.copy function in the loop and i am seeing it isn't moving to the next item. also it tries the same item again .
private void syncbut_Click(object sender, EventArgs e)
{
int filePathList = listView1.Items[0].Index;
int lv2name = listView2.Items[0].Index;
string fileName = listView2.Items[lv2name].Text;
string path = listView1.Items[filePathList].Text;
string path2 = textBox4.Text + fileName;
if (filePathList <= maxFilePath)
{
listView1.Items[filePathList].SubItems[2].Text = "Processing";
File.Copy(path, path2);
filePathList++;
lv2name++;
}
this.syncstat.Text = "Status: All Files Have Copied Successfully";
}
any help would be appreciated!

Where is the loop?
The code you posted has no while,foreach or for loop...it will copy exatly one file (the first) each time it is called.

whoops i thought i would be able to use an if statement to process the loop. I have modified it a bit now but now i am getting an error:
An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in System.Windows.Forms.dll
Additional information: InvalidArgument=Value of '1' is not valid for 'index'.
private void syncbut_Click(object sender, EventArgs e)
{
int filePathList = listView1.Items[0].Index;
int lv2name = listView2.Items[0].Index;
string fileName = listView2.Items[lv2name].Text;
string path = listView1.Items[filePathList].Text;
string path2 = textBox4.Text + fileName;
do
{
listView1.Items[filePathList].SubItems[2].Text = "Processing";
File.Copy(path, path2);
filePathList++;
lv2name++;
}
while (filePathList <= maxFilePath);
this.syncstat.Text = "Status: All Files Have Copied Successfully";
}
i'm trying to get it to start with the first item of the listview [0] then move to [1] and so on till the last one (maxFilePath)

sorry i forgot to add that the error points to:
listView1.Items[filePathList].SubItems[2].Text = "Processing";

Do listView1 and ListView2 contain the same number of Items?
(listview1.Items.Count == Listview2.Items.Count) ?
You are incrementing both...

listView1.Items.Count is where my full path is (example: C:\file.exe) while listview2 is just file.exe
the way i wanted it original is for listView1.items.count to just show file.exe but actually have the value of C:\file.exe (or where the file is located). but i couldn't figure out how to mask on listView. so what i did in an openfile dialog was add the filepath (c:\file.exe) to one listview1 and add just the filename to listview2.
Its kind of hard to understand just by me typing it. I will just keep researching the issue.
