I'm writing an application that prints cassette and cd labels. One major problem I'm running into is that I'm getting varied results on the alignment when data is sent to the printer. Shouldn't I be allowed to draw a line 50 points from the left and it come out 50 points from the left? Right now it is very close but I still get about a 5 point difference between printers. Does anybody have something else that I should be looking at? I am wanting consistency among All printers!
may your code be error free

There is no 'team' at code project, it's a world wide community.

Let me translate this for you.
You asked something several times, I pointed out the only interpretation I could see that could make sense of what you seemed to be saying, now you're saying the following:"
'I didn't mean for you to answer the question that I asked ( badly ), so please answer the question that I have failed to ask'.
We have no idea what you're asking. Try explaining it.

Hello!
I'm trying to use SslStream to connect to server trough SSL. I have take example from Microsoft, modify it for my needs, but I can't use this code.
IOException (Received an unexpected EOF or 0 bytes from the transport stream.) are thrown in function AuthenticateAsClient
See code below
<br />
string Certificate = @"D:\ca.cer ";<br />
<br />
<br />
X509Certificate cert = new X509Certificate(Certificate);<br />
X509CertificateCollection certc = new X509CertificateCollection();<br />
certc.Add(cert);<br />
<br />
<br />
TcpClient client = new TcpClient("dev.com", 443);<br />
SslStream ssl = new SslStream(client.GetStream());<br />
ssl.AuthenticateAsClient("dev.com", certc, SslProtocols.Ssl3, true); <br />
<br />
What is incorrect in this code and what is meaning this exception.
This is not AuthenticationException, then authentication success or not?
Thanks for answers!

You get that error when the file you are trying to unzip already exists on the file system. I think there is an overwrite option when you unzip the file.
Hope that helps.

I am getting so frustrated at people who delete their questions when they get an answer.

I have seen some weird stuff where a file name or path gets truncated. So it ends up being possible that that file exists twice in the zip file. Once in the root and then once in a subfolder, but when unziped the folder structure is not recreated.
Hope that helps.

The zipping process normally involves the use of a temporary file.
I'm unsure if the unzipping process uses temporary files in the same way.
Under XP, many temporary files are stored un the users temp folder in C:\Documents and Settings\User\Local Settings\ which can become full and cause strange things to happen.
This space can be reclaimed by performing a Disk Cleanup from:
Start-->All Programs-->Accessories-->System Tools-->Disk Cleanup
I don't know if this will have any affect? Maybe this will help?

I concur.
How about changing the forums, so a message (original or reaction to it) can only be deleted/modified for as long as there are no replies to it ?

Cross-thread operation not valid: Control 'listBox1' accessed from a thread other than the thread it was created on.

This happens when you try to access a Control on your GUI from another thread. The GUI is run on the "main" thread and only functions running in that thread are allowed to access/use/modify Controls on the GUI. To solve this you need to use Invoke or BeginInvoke to call a function on the GUIs thread to do the work that you want done from a background thread. Check out this[^] article for an in-depth explanation and example on how to solve this problem.

The problem is obvious; You can not access a member of a different thread.
So what is the solution?
1) try "CheckForIllegalCrossThreadCalls = false" statement
2) try to call the modification in the thread where the list box is i.e
- create a function to change the list box
- create a delegate to the function
- use the invoke() method of the class where listbox belongs to.

Ok, this is obviously school assignment, and it's UNIX SHELL PROGRAMMING. What makes you think C# forum is good place to ask for help? If your task is to write unix shell script, write unix shell script, not C# code.

First of all you should change your post title; you are not looking for code, you are looking for a complete homework.
Second instead of wasting your time for searching a complete hw, try to learn shell programming. What you are trying to do can be done very easily. In shell programming you dont have too much option to do.

Hi, ive got a program with a treeview.
The treeview has an image-list with some icons.
Everytime I select a node in the treeview, the icon of that node becomes the first icon in the imagelist.
When I select another node, the icon of this node becomes the first one in the list an the icon of the node that was selected before becomes the right icon.
Maybe someone could tell me what im doing wrong or what to do
|
|
|
|
|
Make sure the imageIndex and selectedImageIndex are defined. Typically this happens when the node is created e.g. treeview.Nodes.Add(key, text, imageIndex, selectedImageIndex);
|
|
|
|
|
YES that was the problem, i didn't know that theres an image index for a selected Node!
Thank you very much! Now it works!
