Take a look at the Configuration Application Block[^]. It's part of Microsoft's Enterprise Library. I used the Configuration Application Block in my last app. and it worked very well. Easy to implement, very flexible and a snap to set up and configure.

Cheers,

Sure, there are three ways:

1) Use Photoshop to load the PDF and simply export it as a TIFF.

2) Use Ghostgum[^] in conjunction with Ghostscript and choose Convert from the file menu.

3) Use a third party PDF library (some of which are advertised here) or one of the free ones on SourceForge to render the PDF file to a bitmap and dump it to a file using .NET or other graphics library, several of which can be found here for free at the Code Project.

I guess I see what you want, although you should really describe in more detail what your problem is, so people wanting to help don't have to guess every detail...

You have a context menu on the TreeView and when you right-click the TreeView, the node you've clicked on seems to be selected, but the TreeView's SelectedNode property returns a different node, right?

If that's your problem, then add a popup event handler to your context menu and set the selected node yourself:

TreeNode nd = treeView1.GetNodeAt(treeView1.PointToClient(Cursor.Position));
if (nd != null)
    treeView1.SelectedNode = nd;

In the menuitem Click handler you can then simply write

treeView1.SelectedNode.Nodes.Add(new TreeNode("A new node"));

Hi all

I am writting a C# program that reads lines from a file. And then store each line in one record in more than one field.

But at the middle of the proccessing a message said that "v\cant open more tables"
here is the pic:
http://www.javadevs.com/problem.bmp[^]
copy the link and paste it in the browser...

And here is my code:

for (int i = 1; i<= Int32.Parse(numNumber.Value.ToString().Trim()); i++ ) {

string cha = answers.Substring(i-1,1);

string anCommand = "UPDATE information SET " + i + "='" + cha + "' WHERE id = '" + id+ "';";
try
{
com = new OdbcCommand(anCommand, dbConn);
com.ExecuteNonQuery();
}
catch (Exception ex)
{
MessageBox.Show( anCommand + "\r\nInserting answers\r\n" + ex.ToString());
stsGrade.Text = "Error!...";
return;
}
finally
{

}
}

It worked for the first 3 lines, but in the fourth line the problem appeared!!
All the lines has the same structure.
I am using MS Access database.
What is the problem?

Perhaps calling Dispose on your OdbcCommand object after ExecuteNonQuery() will help...

That's a great article! However, if you want to understand the details, go into the debugger and see what it's doing, use MSDN and google search for info on classes and methods you don't understand.

To paraphrase, if someone explains it to you, you can program a a data grid. If you learn to explain it to yourself, you can program anything.

C# Text file to PDF

Hi Does anyone know how to generate a pdf(acrobat) from a standard text file? Sigh | :sigh:

There are no tools in the .net framework...
But you can find various components to generate pdf's in the internet. Or, if you don't want to generate your pdf inside a program, you can find "pdf printer"...for example PDF Ghost.

The pdf file format is an open file format, so you could implement your own pdf generator. References can be found in the internet too, for example here: http://partners.adobe.com/public/developer/pdf/index_reference.html#5

There are a couple dozen of them. Google for "C# VB.NET conversion" and you'll find what ye seeks.

Our C# to VB.NET converter, Instant VB, is not free, but you may find the free Demo Edition (converts up to 100 lines at a time) useful (www.instantvb.com).

C#.NET - How to interact with another form?

For example, I have Form1 and Form2, Form1 is parent of Form2.
When Form2 is active, how can I tranfer some values to Form1 components?
Many thanks.

Give Form1 a setter method to accept the values...

//gets called by Form2<br />
internal void SetValues(...){ ... }

...and add an owner-parameter to Form2's constructor.

public Form2(Form1 owner){<br />
this.owner = owner;<br />
}

Then Form2 can send the values to Form1:
owner.SetValues(allMyValues);
