Hi guys,
please help!!! I am trying to delete the printtoprinter job that has already been sent to the printer and then reseting the printer. Is this possible? Is it possible to cancel printtoprinter and to capture a confirmation on whether the report was printed?
Please please please help!!!

Perhaps you could use this[^] article as a starting point for your solution?

Thank you Ravi, I really would hate to change my logic from a simple printtoprinter to a dll based process.

g.AddNode("Diamond");
Edge e1 = (Edge)g.AddEdge("Circle", "Box");
Edge e2 = (Edge)g.AddEdge("Box", "Ellipse");
Edge e3 = (Edge)g.AddEdge("Ellipse", "Diamond");
Edge e4 = (Edge)g.AddEdge("Diamond", "Circle");
Node n1 = (Node)g.FindNode("Circle");
n1.Attr.Color = Microsoft.Glee.Drawing.Color.Black;
n1.Attr.Shape = Shape.Circle;
Node n2 = (Node)g.FindNode("Box");
n2.Attr.Color = Microsoft.Glee.Drawing.Color.Black;
n2.Attr.Shape = Shape.Box;

n3.Attr.Color = Microsoft.Glee.Drawing.Color.Black;
n3.Attr.Shape = Shape.Diamond;
gViewer1.Graph = g;
here is code that i am trying to use to save as an xml file
FileStream fs = new FileStream("methods.xml", FileMode.Create);
XmlTextWriter w = new XmlTextWriter(fs,Encoding.UTF8);

You need to decorate Graph and its contained classes with XML serialization attributes. See this[^] tutorial.

I want to store a Word file into a database (into a field has Image type), and get the Word file from the database to show in RichTextbox. But, when i get a byte array (named content) from database and use :
MemoryStream ms = new MemoryStream(content);<br />
<br />
<br />
richTextBox1.LoadFile(ms, RichTextBoxStreamType.RichText);<br />
to show it in RichTextbox, it throws an exception :
"Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection."<br />
Can you help me ?

Hi,
AFAIK an RTB is capable of showing an RTF file, which you can generate with either an RTB or
with Wordpad. An MS Word document (.doc) can not be loaded into an RTB.

- make Visual display line numbers: Tools/Options/TextEditor/...
- show exceptions with ToString() to see all information

Uhm, what i can use to show MS Word document in my application ?

Hi,
if MS Word is present and .doc extension is associated with it, then a WebBrowser control
should be able to show it.

Hello...
I have a problem in treeview. If the treeview is focused, then I can see that the selection has a backcolor blue. But if focus changed to other control, I cannot see the selection anymore, backcolor is now white, just like another nodes.
How to keep this color blue if treeview is not focused ?
Thanks...

Set the treeview's HideSelection property to false. This will give it a grey background when not focused.

Hi,
I'm trying to add all JPG-Files from a directory to a list box with the help of following code:
const String pathFileSystem = @"\\server\c$\directory\JPG-TEST";
public void loadImagesFromFs()
{
try
{
DirectoryInfo di = new DirectoryInfo(pathFileSystem);
FileInfo[] rgFiles = di.GetFiles("*.jpg");
foreach (FileInfo fi in rgFiles)
{
this.fileList.Items.Add(fi.Name);
}
}
catch (Exception)
{
MessageBox.Show("Couldn't find directory.", "Error");
}
}
The " DirectoryInfo di = new DirectoryInfo(pathFileSystem);" allways throws me an SecurityException. It has something to do with the path. When I use System.IO.Directory.GetCurrentDirectory(); instead of the "pathFileSystem it works. But the path in the const is correct, it works on windows. And with "@" it should be correclty escaped, or not?
When I debug with "GetCurrentDirectory" the path is always with out "\\" (no escaping) but when I use the "correct version, it always has a string like "\\\\server\\directory...", which could be correct, because it escapes the "\" but I'm not sure if it isn't the problem, as it is the difference I notice in this two versions.
Any ideas?
Thx, Shi

I'm sure this is a permission issue. If it "works on windows", then you may have already authenticated and Windows explorer cached the credentials.
Does the user you are running your application have read rights to the path you provided? Keep in mind that the "c$" share is generally used only for admins.
If you reboot, then that should clear any cached credentials (unless you close to save them when prompted).
Take care,
Tom

sorry, I'm normally a Java guy ( oh my gosh  )
Well I tried the access to that share with my account, and on the same machine I'm developing and debugging so I'm guessing it should use the same user to access the share again, or am I wrong?
Is there a way to tell the compiler which use to use for this purpose?

Yes, the application should be run as the user you are logged in as and are running Visual Studio as. Does the exeception provide any specific information (maybe an InnerException?)
It's not something you "tell the complier". The compiler generates an executable and that executable is run under the context of a user. So when your executable tries to list the directory, it's using that user's credentials.
You can run the executable as a different user (than the currently logged in user), using the runas.exe command line tool or right click the EXE in Windows explorer and choose run-as. You can also have your code "impersonate[^]" another user.
Take care,
Tom

I found the solution for the problem...
I also played arround with some database access and it gave me also a security exception. While googling with database+exception-stuff I found following useful site which was the solution for my problem:

"The page cannot be refreshed without resending the information. Click retry to send the information again."

Whenever you do a postback, you need to write your page so that you redirect to the same page, with the pertinent data on the URL. OTherwise, you're just seeing standard browser behaviour.
This was an ASP.NET question.

Hi all,
I have a case where i need to fill in specific fields from a form and save them in specific areas in a word file.
thanks

Depending on which version of Word you are using, you could either open up Word via COM Interop and fill in the fields this way, or generate the file using Xml (Word uses Xml as the basis of the Docx format). Alternatively, you could take a look at VSTO (Visual Studio Tools for Office) and think about hosting the form inside Word itself.

Any links that i can start with especially that i need to save into several files once i fill the main form. Another question is that when i fill all fields with data how can i export/save them to several files without entering to each file alone
thanks
