Hello Jesse,
You are trying to call BeginReceive on the wrong socket. The socket you set up with the Listen() and BeginAccept() requests will simply deliver callbacks to you when clients attempt to connect. In your AcceptCallBack function, you must call EndAccept(), which will return to you a new socket connected to that client. You would then call BeginReceive() on that new socket.
Also, in your Receiver() function, you should use this new socket to call EndReceive() on. The return value from this is the number of bytes you actually received (which may be smaller than you requested.) Note also that if something goes wrong with the network connection, the EndReceive() function will throw an exception, you should be prepaired to handle that.
Hope that helps.

Thanks alot burt, I was looking around on the microsoft website and just now figured out the problem. I noticed in vs.nets intelisence that it said it would hand you a new socket but i didnt know what to do with them. thanks alot for clearing that up for me.
I got the program to work (i wouldnt say work good though) now i just need to get it to work 2 way *send / recieve* now. Thanks agian.
Jesse M
p.s :
How is it working for microsoft ? I live about 2 hours from redmond in Wa. Im currently getting my mcsd / bachelors in college right now... hoping to someday work for microsoft.

hi everyone.. im working on a dialog that is very similar to this article written in C++
http://www.codeproject.com/property/saprefs.asp?target=saprefs[^]
i actually have the whole thing working except one small minor glitch that i cant figure out.. i will be posting an article and provide the dialog as freeware, but i need to fix this glitch first..
basicly when you click on the tree on the left i call this function:
private void tvOptionsTree_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
Form frmSelected = GetSelectedForm();
if (frmSelected == null)
{ MessageBox.Show("An error has occured in the options form which should never occur!\r\ntvOptionsTree_AfterSelect()");
return; }
ShowForm(frmSelected);
}which in turn calls this:
private void ShowForm(Form frmForm)
{
this.SuspendLayout();
if (this.m_frmShownForm != null)
{ this.m_frmShownForm.Enabled = false;
this.m_frmShownForm.Visible = false;
this.RemoveOwnedForm(m_frmShownForm);}
m_frmShownForm = frmForm;
m_frmShownForm.Location = new Point(this.PointToScreen(new Point(0, 0)).X + panel1.Left,
this.PointToScreen(new Point(0, 0)).Y + panel1.Top);
m_frmShownForm.Size = panel1.Size;
m_frmShownForm.FormBorderStyle = FormBorderStyle.None;
m_frmShownForm.ShowInTaskbar = false;
m_frmShownForm.StartPosition = FormStartPosition.Manual;
this.AddOwnedForm(m_frmShownForm);
m_frmShownForm.Enabled = true;
m_frmShownForm.Visible = true;
m_frmShownForm.BringToFront();
m_frmShownForm.Select();
m_frmShownForm.Focus();
m_frmShownForm.Refresh();
}as you can see i put the new form to the front, set it as the focus, enable it, make it visible.. almost everything i can think of.. and it works great.. but..
when the form loads it calls the form load event which in turn calls the tvOptionsTree_AfterSelect function as listed above.. which in turn calls the ShowForm() as listed above.. but i cant click in any of the fields on the dialog on the right hand side which it displayed.. i cant click in a checkbox, i dont get an 'i-beam' when i put the cursor over the textboxes, etc.. as soon as i choose another item in the tree it works.. go back to the starting page and it works.. the whole thing works great after you change the selection on the tree the first time..
ive tried calling tvOptionsTree_AfterSelect multiple times in my form load message handler.. but that doesnt help.. obviously there is something im doing wrong.. the other thing is that when a control in the panel has focus it turns the title bar of the dialog gray, like another dialog has focus.. also my tab order wont go from the main dialog to the subdialog and back and forth.. it cycles through them as seperate dialogs depending on which one has focus.. any suggestions would be much appreciated.. im sure this dialog would help alot of ppl.. i know because the CSAPrefs on CP helped me a bunch in the past..
btw.. i also had to implement moving the subdialog with the options dialog in the options dialog LocationChanged event.. shouldn't it automatically move any child windows when the parent moves? or is it normal to have to override this?
thanks for any and all suggestions!
still a newb.. cut me some slack :P

Hi All,
Does anyone know if .Net 2003's DateTimePicker allows null or blank dates? This problem has forced me to set all dates to '1-1-1900' to simulate a blank date.
Also, did the standard Textbox get the same formatting property as the DataGridTextBox. I find it unreal that this was not in the initial release.
Thanks,
Chris

Hi All,
I am trying to stop the user from going to the last record in a grid, then passing it and creating a 'new' record. I put 'new' in quotes because it does not have a DataRowState value of added and I can not stop it from happening.
I need to not allow this to happen for various reasons, one is security. I have a user level controlled button to perform a NewRow(datarow) for this table in the grid.
Any help would be appreciatted.
Chris

You need to set it in the data view
<br />
((DataView)((CurrencyManager)this.BindingContext[dataGrid1.DataSource,dataGrid1.DataMember]).List).AllowNew = false;<br />
<br />
<br />

Thank you very much. It still allows me to add my new row by .NewRow(nr), but does not allow the automatic new row in the grid. Just what I needed.

If I dig into MSDN files, the help on creation of context-sensitive help states that I do the following:
eliminate Minimum and Maximum buttons,
add the HelpProvider to the form,
populate HelpString with the text I want displayed
Now what this does is require the user to
click the ? on the menu bar,
mouse-over the control in question,
left-mouse-click the field
What I get is a small, yellow window with the text compressed into a small display area.
I've constructed a full help file for the application which included help at the screen level with invisible topics for the various controls. I assigned context topic numbers to each topic with a unique keyword assigned to each topic and I TRIED to get the helpProvider properties set:
HelpNavigator = (I cycled through EVERY option)
HelpKeyword = context ID, topic, hidden topic name, unique keyword
When I place the cursor inside a control and hit F1, all I get is the help file positioned to either Contents, Index, or Search and the displayed help page is the Welcome page (first page in file)
Doesn't the HelpProvider support standard context help anymore? What am I missing?
Later

When my C# service is configured to use any account otherthan SYSTEM it does not show up under the .NET CLR Memory performance counters. This seems like a bug? Can anyone else confirm this? I'm using version 1.0 in WinXP Pro.

I have a Windows Forms application that requires to read an XML, i know you can put something like
<add key="serverPath" value="http://localhost/something.aspx">
but in the case the value is XML what can I do? i tried to put the xml inside the value but it didnt work
<add key="test" value="<hi>">
i had to do it this way
<add key="test" value="<hi>">
that worked, but it would be too hard for the user to edit and not make mistakes when the XML grows, so i was wondering if there is any way I could just put my xml tags somewhere in the .config file where it doesn't make the application crash
something like this
<configuration>
<appsettings>
<add key="serverPath" value="http://localhost">
<mytag>
<moretags>blah
I basically want to avoid that some settings are stored in the .config file and others in a different XML file
Thanks in advance

this is getting complicated to post
when i wrote "i had to do it this way" and the sentence looks identical i wrote
& lt; hi & gt;
the question at the end is can i add my own tags to the .config file?
Thanks

Damn the board did it to me too.
<configsections>
<customsettings>
<add key="x" value="y">
Reading your custom section
GetConfig("customsettings")("x")
Hope this helps

I have a menu which I have to owner draw the few menu items which contain icons. I snagged the code to do this from Petzold's Prgramming Windows in C# book. It helped a lot, but one thing that bothers me is the hardcoded font size and unknown style.
It comes up looking odd because the font is slightly different than the rest of the context menu.
I need to to find two items.
1. Default system font and font size for menu items.
2. Background color
Default size and font to match font itself. Is there something like SystemColors class that I can get into for the proper font style adn size for menu items.
When 2 is discovered, how do I changed the background color of the drawn menu item rectangle? It looks fine on my machine which is XP and the background is white already. When I ran my proggy on Win2K, the regular items had the standard silver/gray background, but my owner drawn items have a white background. Yuck!
Example of my current owner drawn menu items (measure and draw) are below for reference.

Hi there,
I have partitioned my hard drive and loaded my visula studion.net in D: drive. I have created a virtual directory, ASP.NET and mapped it to D:/asp.net .When I was trying to compile a small c# application using csc.exe at the command prompt(csc FirstApp.cs) its popping up the following error message.
'csc' is not recognized as an internal or external command,
operable program or batch file.
I guess its coz' the path isn't set up. But i don't know how do i set the path for c# compiler. Please help me some one.
thanks in advance

I suggest you to copy this shortcut to a shorter path

I want to write a subroutine which fetches data from a database, save column to a hashtable (columname=columnvalue) and then put each dataset hashtable into an array ... then i want to return this array to the main program and run through each element and dereference the element back to a hashtable ... in perl i know how to do this - but have no clue how this had to be writen in c# ... (perl: %hash = %$array[element])
i trie something to put a hashtable into an array of string[] but i don't know how to get the hash back from the element of the string[] ...
Thanks for your help!

This may seem obvious, but have you tried System.Collections.Hastable? If you are working with only strings, the System.Collections.Specialized.NameValueCollection may offer better performance..

HashTable[] ha = new HashTable[number_of_elements_in_array]();<br />
<br />
HashTable h = new HashTable();<br />
h.Add(key, value);<br />
<br />
ha[array_element_number] = h;<br />
Now you pass your ha array around, and get the hashtables back like this:
<br />
HashTable h = ha[array_element_number];<br />
If you defined your array in another way, like object[] or so, you will have to do a cast when retrieving the hashtable.

Sounds like your trying to apply Perl design to a C# program. Before you go too far, you should first try to understand the database access classes in the System.Data namespace. A DataTable acts a lot like an array of DataRows, where individual fields can be accessed by name.
But if you really want something like a perl array of hashes, it might look like this:
using System.Collections;
...
ArrayList a = new ArrayList();
Hashtable h = new Hashtable();
h.Add( "One", 1 );
h.Add( "Two", 2 );
a.Add( h );
h = (Hashtable)a[0];
Console.WriteLine( h["One"] );

I have a Form with a toolbar. The toolbar contains some Buttons with Text like "&New", "&Edit", ...
I meant that marking the Buttons as HotKey is enough to allow access via ALT+"N", ALT+"E", ...to fire the ClickEvent.
So how is it possible that Toolbar Buttons react on Keyboard Inputs like normal Buttons with HotKey?
Thanks
Stefan
