If your TCP socket connection variable (TcpListener or whatever you're using) is declared in the event handler, then it will be garbage collected when it goes out of scope (and when the GC gets around to it). You need to at least declare it outside of your event handler, just like buttons, text boxes, and other UI components are declared as fields and initialized in a method.

did a program that lists stats for creatures that will combat each other. Need some help to clone this object for the users desired number of fighters and then each winner will combat the other winner until there is one winner.
i am new to this stuff. hope i am not asking to much or even if it is bad manners or anything.

If you're new to .NET development, why don't you start creating simple applications and reading the vast number of articles on .NET development (with C#, VB.NET, and other languages) on sites like CodeProject?
If you want to write an application, this is not the place for help to write an entire application. This forum - and pretty much any other forum you'll ever find - are for specific problems or questions, not to help you write an application from scratch. That requires actually knowing something about programming, and only you can discover that.

I agree with what you said, but I sometimes think that OOP would be a good topic for a discussion board. Did anyone ever suggest that?

Hi
I developed a new open-source filebrowser with c# that i want to share with you.
You can download it here:
www.slender.be
The application runs very nice but contains also some errors. When you are searching for a file. Sometimes i got a thread error. And the progressbar in the move/copy dialog doesn't work very good.
I hope you can help me developing this application.
(if you don't want helping me, you can always try to use it.)

hello,
I'm using an Xml-file to fill my dataset and i place the dataset in my datagrid. My problem is that when i click a row in the datagrid, i want the data in text and/or checkboxes that are placed below the datagrid. Is this possible?
thx in advance!

In a handler, you can get the CurrentRowIndex of your datagrid. You can use this to get values from your cells. You shouldn't have much trouble putting them into your other boxes below the grid.
something like
textBox1.Text = dataGrid1[dataGrid1.CurrentRowIndex,0].ToString();
You'll have to play around with it a little. Good luck

Hi Appelz,
Following code will get you the text in the DataGrid cell where mouse is being clicked.
Paste the following code in MouseUp event of the DataGrid Control.
private void DataGrid1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)<br />
{<br />
System.Drawing.Point pt = new Point(e.X, e.Y); <br />
DataGrid.HitTestInfo hti = DataGrid1.HitTest(pt); <br />
<br />
if(hti.Type == DataGrid.HitTestType.Cell) <br />
{ <br />
string str = "";<br />
str = DataGrid1[hti.Row, hti.Column].ToString();<br />
MessageBox.Show(str);<br />
} <br />
<br />
}
Do revert back, whether you could achieve the functionality or not.
Regards,
Jay.

yes thank you it works well
But i put what is in the messagebox, in a textbox so it can be edited.
Now i added a button and if you click on it i want the data added in the textbox back into the grid (in the right cell).
is this possible or too difficult because i can't make it work?

|

Hi Appelz,
try the code below
DataGrid1[hti.Row, hti.Column]=textBox1.Text;<br />
DataGrid1.Invalidate();

Jay

Hi,
I'm looking for an event / function that gets called when your assembly gets loaded.
The problem now is that I declare a static member variable in a class which only gets initialised when the class is explicitly used. This variable however has to be initialised for every class which is used in the assembly, but without having to go through the trouble of putting code in every class' constructor.
The reason why this variable has to be initialised when the assembly gets loaded and before any class is constructed is because this variable init checks whether the user has a valid license to use this assembly.
Thanks very much in advance,
Arthur van der Wal

Look down in the "autos" section. Look at the variable naming one of your data structure variables. It should have a little expandable plus sign-- click on that and you will see the values it contains.

Word of warning to the original poster, though - this doesn't work very well at all for Hashtables. You have to dig deep to find any relevant data.
In VS.NET 2005, they are adding new debug views, such as extensible tooltips and data viewers to solve problems such as this. DataSets are also difficult to debug so they would have a view associated with them that lets you view (and modify) the XML data in a text box or view it using MSXML hosted in Internet Explorer, as well as a generic DataGrid (last time I checked).

I'm using VS.NET 2003, and it works-- although it's a little confusing. The top "twistie" expands to show all the entries (haven't tried it on large numbers of entries), and then each one of those expands to show the details of the data element of the mapping. I seem to remember once trying to peer into a Hashtable during debugging on 2002 and having the IDE hang, but at least that's not happening now.

I know it works, but the important part was "well".  Perhaps I mis-phrased, but that's basically what I meant: that it was a little - as you put it - "confusing".

I wonder if there is a difference in view between the regular watch window and the one used by quick watch. The quick watch one doesnt seem to show me the obvious details like you mentioned(lot of digging around to get to the data gives a really frustrating experience) I got to try with the watch window though.

I rarely use the watch windows at all. Try the Autos, Locals, and This debugging windows. Autos uses the variables relevent to the current line you're debugging; locals is all the variables in the current scope (including fields, IIRC); and This is all the variables for the current object you're debugging. They show you a lot of information and don't constrain you to whatever you put (or forget to put, more importantly) in the watch windows.

how can i call a console window and console result(out put) in windows application.

In VS if u make the target app a console app and in your main form make ti load just like a windows app it will load both the console window and the windows form. Best way to do it is to. Make a windows form application then goto project proporties and change ti from windows app to console. Then you can use Console.writeline(); and watch the code. Might be other ways too though.
