Re: Can we get program's number line after compiling the source ?

22-Jun-08 12:59

Hi there.
Already I was using PHP .
In PHP we can get program's number line, for example the following code writes 9 in out pot.

1	<?php 
2	 
3	// 
4	// 
5	 
6	 
7	/// 
8	 
9	echo __LINE__; 
10	 
11	// 
12	 
13	?>

Now , I want to know whether we can get program's number line in C# when the program is running?

M-Dayyan,

AFAIK, I don't think you can. Whats the reason you want to print out the line number?, i am guessing its debugging related?

Regards,
Gareth.

Hi,

it is possible, but not very easy; there is no predefined symbol as in C/C++.

you can figure out where you are (and how you got there) by reading
Environment.StackTrace; you could even create a method that takes the second
entry (skipping the method itself) to extract the classname, methodname, and
line number.

The line numbers may or may not be present depending on circumstances such
as debug/release build.

I must using

StackFrame CallStack = new StackFrame(0, true);
Console.Write("File: " + CallStack.GetFileName() + ", 
Line: " + CallStack.GetFileLineNumber());

daContactsCombo.Update(dtContactsCombo);
}
}

}
}

As I stated before I am new to C# and any help would be appreciated.

Sorry - I get an SQL Error at the line: daContactsCombo.Update(dtContactsCombo);

Syntax error in query expression '((Contact_ID = ?) AND ((? = 1 AND First_Name IS NULL) OR (First_Name = ?)) AND ((? = 1 AND Last_Name IS NULL) OR (Last_Name = ?)) AND ((? = 1 AND Company_Name IS NULL) OR (Company_Name = ?)) AND ((? = 1 AND Job_Title IS NULL) OR (Job_Title = ?)) AND ((? ='.

Thanks for all your help

I don't think it works like that.

Definately this won't work, you have two brackets ( for no good reason ) and they are not closed.

Yes, so the string you're using for your query, is wrong. That is what I am telling you.

Are there any good examples of doing this using Access?

Thanks Again.

I'm not sure what you mean by 'doing this', it looks to me like you're asking a SQL question and all you need to do is close your brackets. Where is the issue ?

Drog and Drop question ?

Assumption , we have a TreeView in C# form and each node of TreeView contains web address.

Now, I want drag a node into the IE browser as IE opens its web address.

How can we do it ?

I guess the question you need to ask is, what format of drag and drop, if any, does IE support. If it has support for something like this, you need to write code to conforms to what IE expects.

A quick google leads me to believe that IE has a drop event handler, so if you had IE in your own window, as a control, you could handle it. I don't see anyting else, but if you try to google it, you may find something.

OK, i finally got it. IE expects Files (which we already knew right?). After a little investigation it turns out the a FileDrop is just an array of strings (usualy with just one string in, go figure).

So, simple enough:

void TreeView1ItemDrag(object sender, ItemDragEventArgs e)
{
  string[] stuff = new string[1];
  stuff[0] = @"http://www.google.co.uk"; // or e.Item.ToString() or however you've got your address in there
.
  //Create a new data object with the FileDrop type
  DataObject data = new DataObject(DataFormats.FileDrop, stuff);
.
  //And IE only wants Copy, it doesn't like move or whatever
  this.treeView1.DoDragDrop(data, DragDropEffects.Copy);
}

So, IE will get this info, check the array of strings for the file to open, find your web address, and open it.

My current favourite word is: I'm starting to run out of fav. words!
