Hello. I'm using the socket class in an application and I use socket.receive
to wait for data. The problem is that the interface gets locked while the
receive method is executing.
I want to see the interface so the user knows what's happening at any time.
Is that possible?

Diego F.

I found a problem with that. Now, I can't access the UI controls, as they are in other thread. I get an execution exception.
How can I solve that?
Regards,
Diego F.

You can use the Invoke method on the control or form to run the method you are calling on the correct thread.
|
|
|
|
|
You might be getting the cross-thread exception.
try this
<br />
public void UpdateMenus()<br />
{<br />
if (this.InvokeRequired)<br />
{<br />
this.Invoke(new UpdateMenusDelegate(UpdateMenus), new object[] { sender, e });<br />
return;<br />
}<br />
}<br />

Youc can also use BeginReceive and EndReceive to achieve the same. This moves the thread handling to the Socket class. If you are doing lots of operations then you might want to do the thread handling yourself.

Hello Guys,,
I need to send a int pointer to the C dll . The c coding is as follows
extern __declspec (dllexport) void __stdcall TestIntPointer (int *uiPosition) {
char cMessage[100] = {0};
*uiPosition = 55;
*(uiPosition+1) = 80;
*(uiPosition+2) = 100;
wsprintf (cMessage, "Integer Value Received is :%d:", *uiPosition);
MessageBox (NULL, cMessage, "Hello Sweet Heart", 0);
}
My DLLImport statement is looks like this
[DllImport("TestDLLInvocation.dll", CharSet = CharSet.Ansi)]
private static extern void TestIntPointer(IntPtr s);
Now i need to access all the three int values 55, 80, 100 in my C# coding
How can i do this.. Please help..
Thanks in Adv
Sundar

You can actually manipulate pointers in C#, in an unsafe block.

Pretty simple to do, but you need to use HttpWebRequest for this.
HttpWebRequest request = HttpWebRequest.Create("http://19.19.19.1/UpdateProgram/sa.exe");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
StreamWriter writer = new StreamWriter("C:\\Temp\\sa.exe");
while (!reader.EndOfStream)
{
writer.Write(reader.Read());
}
reader.Close();
writer.Close();

Hello,

I really can't believe that!
YourTextBox.Multiline = true;
YourTextBox.ScrollBars = System.Windows.Forms.ScrollBars.Vertical;
All the best,
Martin

You must look at the properties again
bcz there is a property for multiline

You can use the "System.Windows.Forms.Help" Class.
This class Encapsulates the HTML Help 1.0 engine.
and use this function to open ur chm file :-
Help.ShowHelp(YourParentForm , YourchmHelpFilePath , HelpNavigator)

I am trying to decompress a file. To do this, with my current code which you can see below, I am reading the entire file into a byte[]. But if my file is big, I believe bigger then 64 KB, then I can't declare a byte[] big enough to hold the file. How do I fix this, work around this?
---------Code---------
public void GZipDeCompressStream(Stream InStream, Stream OutStream)
{
//Decompresser
GZipStream gzDecompressed = new GZipStream(InStream, CompressionMode.Decompress, true);
//Retrieve the size of the decompressed file from the compressed footer
byte[] bufferWrite = new byte[4];
InStream.Position = (int)InStream.Length - 4;
InStream.Read(bufferWrite, 0, 4);
InStream.Position = 0;
//Convert to int for using in declaring our Byte[] size
int bufferLength = BitConverter.ToInt32(bufferWrite, 0);
//Create our Buffer: size + 100
------------//This is where my issue is. Buffer Lenght is WAY bigger then the 64 KB limit.
byte[] buffer = new byte[bufferLength + 100];
int readOffset = 0;
int totalBytes = 0;
// Loop through the compressed stream and put it into the buffer
while (true)
{
int bytesRead = gzDecompressed.Read(buffer, readOffset, 100);
// If we reached the end of the data
if (bytesRead == 0)
break;
readOffset += bytesRead;
totalBytes += bytesRead;
}
// Write the content of the buffer to the destination stream
OutStream.Write(buffer, 0, totalBytes);
// Close the streams
InStream.Close();
gzDecompressed.Close();
OutStream.Close();
}

is long bigger than int in C# ? I thought it was.

This post does not make sense in the context of my question, or you didn't explain yourself well enough.

You're storing the size in an int. A long is bigger.

Ahh. The problem wasn't int being big enough. The problem was making a byte[] that was big enough. My byte[]'s total size in memory was greater then 64kb. The other post though should solve my issues.

Yeah, long is System.Int64, and int is System.Int32;
