Don't use Nodes.Add(string) use Nodes.Add(TreeNode)

Actually, i am adding a node, i just used text to help the example. So err, still kinda stuck here.
|
|
|
|
|
Is there any way i can do this:
TreeNode folder = treeView1.SelectedNode.Nodes.Add(oNode);
folder.Nodes.Add(TreeNode);
It comes up with 'can't implicitly convert int into TreeNode'
It doesnt have this problem if i'm adding text as a node, only when i add an object as a node.

oNode is a TreeNode, so all is good, i can add it to the treeview, but i want to give it children <-- that sounds wierd

how about TreeNode.Nodes so if oNode is a TreeNode then:
oNode.Nodes.Add( anotherNode);

Hi,
I have to build a layer of serviced components over a DAL (data access layer). Now this DAL was written using interop in VC++.
I built my component using a snk - which worked fine till i added the code to access DAL. Now it gives me an error sayin that assemly cannot be created as DAL does not have a strong name.
How do I get rid of this problem? How can i reuse the existing component without having to rewrite it in .net environment?
I recently read an article sayin that i would have to generate a strong key for the interop dll using tlbimp... but i somehow am not able to figure the parameters out ... has anybody done this?
Any help will be appreciated!

Hi,
I'm developing a remote application, which means a windows application that controls an existing windows application by using the Win32 API (SendMessage, FindWindow, etc.). Problem is the following: The other application, which already runs and has to be controlled, has a button, that opens an OpenFileDialog, when being clicked. My remote application does so by sending the appropriate message to the other form. The OpenFileDialog is shown, but my remote application stops processing its code, it doesn't continue working (easy to see in debugger: code is executed till button click command is sent, then everything stops. If I manually cancel the OpenFileDialog, rest of the code is executed)! This is a situation that I want to avoid, I want the application to work on. Any ideas how to circumvent that?

How do I write a "Hello World" string stored in a (*.txt) file to the Console output?
using System;
using System.IO;
//Is this the right idea??
//Please-- show me CODE not the "just use use a "-----" answer....
namespace StreamReaderWriter
{
///
/// Summary description for Class1.
///
class Class1
{
///
/// The main entry point for the application.
///
[STAThread]
static void Main(string[] args)
{
// TODO: Add code to start application here
//@"C:\Documents and Settings\Desktop\Text01";
string file_name = (@"C:\Documents and Settings\Desktop\Text01");
StreamReader fReader = File.OpenText(file_name);
StreamWriter fWriter =
File.CreateText(@"C:\Documents and Settings\Desktop\Text01");
//Now, how do I get the "Hello World" in the text file
to the console output??
}
}
}
thanks a lot for your help.....

Console.Writeline(fReader.readline());

Have you tried reading the documentation for StreamReader?
From MSN Search[^]you can find the top two links will take you to the StreamReader Class documentation[^]. There you will find a table with lots of handy "How to..." links. One of which takes you to Reading Text From A File[^] which shows you step-by-step exactly what you are trying to do.
Does this help?

Sorry for my mistake, here is the correct line
Console.WriteLine(fReader.ReadLine());

With apologies, I just rotate through cool stuff I have copied and pasted in a sigs text file. Perhaps you can take it as a compliment rather than an offense

Oh no. I do take it as a compliment.
I guess even the smilies around my very poor joke didn't work. (Since starting to work in Glasgow I'm picking up their very cynical sense of humour - And I move there next month so I guess it is going to get worse!)

for heavens sake, when a hint is given to you you should at least try it.
Anyway, I also was happy when people helped me with my probs, so here is my suggestion:
private void InitializeStreamReader()
{
System.IO.FileStream fstream = System.IO.File.OpenRead(@"c:\test.dat");
System.IO.StreamReader sreader = new System.IO.StreamReader(fstream);
string[] filecontent = sreader.ReadToEnd().Split('\n');
sreader.Close();
foreach (string contentTemp in filecontent)
{
Console.WriteLine(contentTemp);
}
}
Here is a short explanation what is done in this example:
A Filestream is created
A Streamreader which uses the Filestream
the streamreader reads all the content of the file an splits it by the new lines
(every new line is a new element)
these elements are used in a string array
the streamreader is being closed
and now to the interesting part:
every line in the string array is being displayed via console.writeline
Of course it can be done easier, but I think you´ll like it this way as well

Ive been trying to find an example on how to make a progress bar progress with the copying of a file using the copyTo command. does anyone know how to make it work?
|
|
|
|

You won't be able to do a real progress bar with File.Copy because it is synchronous and does not give any feedback as to the overall progress of the operation.
You could easily do this yourself, however. Open the file you want to copy, and create a destination file you want to copy the file to. Read in the source file byte-by-byte, and write those bytes to the destination file. Every few bytes, raise an event indicating the overall progress of the operation. Interested components would simply listen to that event and could update the value of a progress bar if they wanted.
