Hi Diego,
First off, this is a C# forum. It is not that I want to be picky, but I hate looking at VB.NET code, it gives me rash.
Second, your socket reading code is not familiar to me, but this is not the kind of code I would be using. Use a while this way instead:
int nbBytesRead;
while ((nbBytesRead = sock.Receive(bytes_recibidos)) > 0)
{
datos_recibidos = (System.Text.Encoding.ASCII.GetString(bytes_recibidos)).TrimEnd(Chr(0))
....
}
I don't recommend using the Socket.Poll method in a loop. Use it once before the loop, if you want to see if there is data available. Also, you don't need to check for the Socket.Available method, since if Poll returns true, there is data available to read.
I don't know what your application does, but if you expect the server to return data immediately after connecting to it, there is no need to Socket.Poll your client socket. Just use the Socket.Receive, which blocks until data is available. If in your application you don't want to wait undefinetely for data, use the following code after creating your socket:
sock.ReceiveTimeout = 10000;
Good luck.

The reason why you always get 8192 bytes is because you don't use the number of bytes returned by the call to Socket.Receive.
In my other post, replace the following statement:
datos_recibidos = (System.Text.Encoding.ASCII.GetString(bytes_recibidos)).TrimEnd(Chr(0));
with:
datos_recibidos = (System.Text.Encoding.ASCII.GetString(bytes_recibidos, 0, nbBytesRead)).TrimEnd(Chr(0));
I cannot see the complete code from your while, but in the loop that does not have the complete number of bytes (10000 minus 8192), the call only overwrites the first 1808 bytes in your array, leaving the rest with bytes from the previous read loop.
The Encoding.GetBytes method does not copy the string terminating character (\0) in the array of bytes on the server side.

Ok, I did change it. Thank you for your advise.

First of all, my excuses for posting here. This should be in VB.NET subforum.
Anyway, I found the mistake. When I do sock.Receive, the array isn't cleared. I didn't expected that, but if I read 100 bytes and the time before it was 150 bytes, the last 50 bytes are from the first time.
So I used the Array.Clear method and I avoid that problem.
Regards,
Diego F.

Diego, it is not the right way to do it. Use the value returned by Socket.Receive to know how many bytes are read. Read my 2 other replies to your post (the one you show the code used).

Hi guys , just wondering if anyone knows much about global mouse hooks in c#. I ve basically used this tutorial to implement a simple hook that can grab mouse clicks and x & y.
http://www.codeproject.com/csharp/globalhook.asp[^]
I now have a requirement where I need to specifically get the name or text associated with the item ive clicked on. IE if I clicked on the 'File' menu in wordXP id like to be able to get the word 'File' and store it in a variable for future use.
Iam pretty sure this task is going to involve monitoring windows messages but iam not really sure where to start. does anybody have any experience in this area?
Thanks Mike

I have an C# ASP.NET web page. I have this conversion problem with my string array to my session variable.
string[] stModArray = (string[])Session["modArray"];
Any suggestions...... Thanks in advance!!

Hello,
As the Session["modArray"] is only returning a string or null you can not cast it directly to string[].
You would have to create an string[] instance and add the result string to the array (at the index you would like it to be).
To make it dynamic, you caould use a System.Collections.Specialized.StringCollection (with the "add" method) instead of string[].
P.S.: allways make a !=null check.
Hope it helps!
All the best,
Martin

Do this:
object o = Session["modArray"];
and check in the debugger to see what's actually stored there. If it's not a string[], you can't turn it into one, at least not like this.

Ok, what I have in this variable are three primary key numbers, so what's getting stored is an int. But the reason why I'm using a string is because I need to return the length for my for loop so the user can cycle backwards and forward viewing each record.
-> There are no nulls getting passed in, what's getting passed in is correct.
This is the snippart of the code that I'm using to try and do what I've just explaned. Once again since I'm I using a loop, objects and such don't have the length function :'(
private void nextMod()
{
string[] stModArray = (string[])Session["modArray"];

Hi,
I have some custom controls and all have methods BeginInit() and EndInit() in it.
In most cases both methods are empty and probably will always empty.
Is there any performance problem, because I notice in myForm.designer all controls have this two lines:
((System.ComponentModel.ISupportInitialize)(this.crLabel20)).BeginInit();
(System.ComponentModel.ISupportInitialize)(this.crLabe20)).EndInit();
I suppose for all controls both methods are called at runtime. Is this performance wasteful?
Thanks and sorry my english,
Jure

Hello,
Tavbi wrote: I suppose for all controls both methods are called at runtime.
Yes, it will be called from the constructor (InitialzeComponets) of your form. (When you initialize your form)
Tavbi wrote: Is this performance wasteful?
No!
I wouldn't care too much about it.
But maybe if you don't need it at all, you should think of removing it, just to make the code simpler.
All the best,
Martin

Err but it looks like these were generated by VS. I wouldn't touch them.

No, No, No!
What I mean is removing the interface from the Custom controls (labels,...)
Hope he understood it.

Since that's deigned generated code, the changes you make in there will be overwritten the next time the designed refreshes it. You can also break the designer by messing with that code too!

This must be the seventh time you're asking the same question in the last few days.
Last time kubben asked you if you have tried HttpWebRequest.ClientCertificates and you didn't answer.
HAVE YOU??

Hi all,
I have to switch from one application to another,
I have found this method:
System.Diagnostics.Process.Start("application");
that allow me to open an application...
Then when i press my button for the second time, i don't want
to start a new application but i want to open the existing one.
in this way:
System.Diagnostics.Process[] myProcesses;
myProcesses = System.Diagnostics.Process.GetProcessesByName("application");
i can know if my process is already running but now I don't know
to show this application...
Can someone help me??
Thanks a lot.

Hello,
You could use the MainWindowHandle property of the process in combination with BringWindowtoTop method of user32.dll.
[System.Runtime.InteropServices.DllImport("user32.dll")]
public static extern int BringWindowToTop(IntPtr hwnd);
public IntPtr HWND_TOPMOST =(IntPtr)(-1);
public IntPtr HWND_NOTOPMOST =(IntPtr)(-2);
System.Diagnostics.ProcessStartInfo psi;
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Maximized;
psi.FileName = "???.exe";
using(System.Diagnostics.Process process = new System.Diagnostics.Process())
{
process.Start(psi);
process.WaitForInputIdle();
BringWindowToTop(process.Handle);
}
I'm using this in .Net1.1, maybe in .Net 2.0 there is a more elegant way.
Hope it helps!
All the best,
Martin
