System.Diagnostics.Process QueryProcess = new System.Diagnostics.Process();
String command = @"ipconfig/all";
QueryProcess.StartInfo.FileName = command;
QueryProcess.StartInfo.Arguments = " >c:\\a.txt";
QueryProcess.Start();

You could always stream the StandardOutput to a file - See the docs on MDSN for the System.Diagnostics.Process class

Hi,
I was wondering if there is a way to get all data from the serialport before processing it.
I got an event handler for the serialport and this is how i receive the data:
string buffer += serialport.ReadExisting();
These are my delegate and event to read the data:
public delegate void GetData(string getDataFromBuffer);
public event GetData getTheData;
After that this event handler is fired:
if (this.getTheData != null)
this.getTheData(buffer);
All data i get will be appended to a richtextbox. Problem is, it keeps appending even the data already exists.
It kinda looks like this:
123.
123.455
123.455.5677
But i want to append it all at once.
Any suggestions how to fix this?
Thanks in advance!

Hi,
If you only want to keep the latest text only, then dont concatenate the original text with the new one.
I think you might be doing something like this -
RichTextBox1.Text = RichTextBox1.Text + this.getTheData(buffer);
Change it to
RichTextBox1.Text = this.getTheData(buffer);
Hope i got what you want, but i am not sure about it.

Hi,
I got it exactly like how you suggest it to do.
But the buffer still has its data from the previous serialPort.ReadExisting(); execution.
|
|
|
|
|
serialport.DiscardInBuffer();

I had this problem too. When I debugged it, I noticed that it was calling my event handler twice if I changed from one selected item to another, but only once if I had nothing selected and I clicked one. This makes sense because when the selection changes from one item to another, it has to deselect the current item, which fires the 'Changed' event, and then it selects the new item, firing the event again.
The first time the event gets called, there is no selection (SelectedItems has a size of 0), so you will get an InvalidArgument or possibly the "Object reference not set to an instance of an object" error. All you need to do is add a check to see if any items are selected. You can do that by examining the Count property of SelectedItems.

Hello,

I put "C# custom explorer sample project" into Google and found this:
http://www.codeproject.com/useritems/ExplorerTree.asp[^]
Usually when you do your Google queries for this kind of thing, if you put the language or technology you want to use, it will come back with pretty good responses. This was the third result, and I think it should answer your question.

 Hi sir,
I wrote a app.config as follows
<appsettings>
<add name="dbConnection"
="" connectionstring="data source=MANGALA;initial catalog=Northwind;persist security info=False;user id=sa;pwd=sa;workstation id=MANGALA;packet size=4096" providername="System.Data.SqlClient">
I called that connection string like this,
SqlConnection cn;
sConn = System.Configuration.ConfigurationManager.AppSettings("dbconnection");
cn = new SqlConnection(sConn);
cn.Open();
then it is an error :
The type or namespace name 'ConfigurationManager' does not exist in the class or namespace 'System.Configuration' (are you missing an assembly reference?)
I am a beginner for c# can you help me?
thank you

Collapse your project in the Solution Explorer window and right click 'References' and choose 'Add Reference'.
A popup window appears, on the .NET tab, choose System.Configuration and press the OK button.
Try rebuilding your project
