IIRC you should not send more bytes than the buffer size at a time.
|
|
|
|
|
I've tried changing the buffersize to a bigger number (on both the client and the server of course) but anything over 1024bytes doesn't have any affect. 
If the buffersize is SendBufferSize and ReceiveBufferSize on the TCPClient.

Does anybody know how to parse something like "Fri, 31 Mar 2006 09:24:25 PST" into a DateTime?
/\ |_ E X E GG
|
|
|
|
|
Using DateTime.Parse() or DateTime.ParseExact() ?
Regards,

I keep getting the exception:
System.InvalidOperationException was unhandled
Message="Update requires a valid UpdateCommand when passed DataRow collection with modified rows."
when exicuting the following code:
myDataTable.Rows[intRowPosition]["Notes"] = txtNotes.Text;
myAdapter.Update(myDataTable); //Error on this line
The MSDN says that its due to The source table being invalid.
I was also wondering if something in my connection string would cause this issue, if i had to specificly set a two way connection, but I am able to pull data and requery the connection at run time... so i dont think it would be an Access DB issue.

{<br />
WebRequest req = WebRequest.Create("http://www.google.com");<br />

Question is simple -> how come my code hangs on second line? I tried it on two computers (.NET 1.1) and it won't work. After some time I get WebException (The operation has timed-out).
Any help is greatly appreciated.

Use a HttpWebRequest to start with:
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.google.com");

Hi.Can anybody explain me how this function works cause Im trying to understand this code...
public static double[] convertPolyList(String theStr)
{
// initialize return value to unity
double[] theResult = {1};
// polynomials seperated by ']' characters
theStr = theStr.replace('(', ' ');
theStr = theStr.replace('[', ' ');
theStr = theStr.replace(')', ';');
theStr = theStr.replace(']', ';');
theStr = theStr.trim();
StringTokenizer theToken = new StringTokenizer(theStr, ";");
int index = 0;
for (index = 0; theToken.countTokens() > 0; index++)
{
double[] theArray = convertPoly(theToken.nextToken());
theResult = multiply(theResult, theArray);
}
return theResult;
}
|

Can you clarify your question?
It filters the string, removing opening parens and brackets, and replacing the closing ones with ';', then it removes all the spaces.
StringTokenizer iterates through the string, treating it kind of like a list broken up at the semicolons.

Is there some trick to using this method?
I looked up code samples and they are all just one line:
Environment.SetEnvironmentVariable(strName, strValue);
Yet when I do it, nothing is changed... I'm trying to modify the PATH variable by the way
|
|
|
|
|
[DllImport("Kernel32.dll")]
public static extern int SetEnvironmentVariable( string name , string value ) ;

It's integrated into VS2005, but I tried that anyway=).
importing that is the same as doing Environment.SetEnviornmentVariable()
|
|
|
|
|
|
Very odd...
Doing that I get an error on this line:
envObject["PATH"] = sPath;
Error reads:
Unable to cast COM object of type 'System.Management.WbemDefPath' to interface type 'System.Management.IWmiSec'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{2FD73A3B-64B3-480D-AEE9-54469D77123E}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).

You realise the values will only be changed within your current process? And will not be persisted?
|
|
|
|
|
Then how do i Change the actual values? I've also tried changing them via registry and making a sendmessage call to 'update' them, but it didn't work.
|
|
|
|
|
|
I've tried a few variations of that SendMessage attempt...

I am writing a small Wx app and need to access a file on the HDD to fill a combobox.
I am using StreamReader and ReadLine to get it into the box. I have moved the file to the root, the file has no permissions set. Each time that I run the app it errors to the catch and tells me that it cannot find the file.
I have tried File.Exists( file ) and it also tells me that it is not there.
I have used @"c:\nex_tex.txt" and "c:\\nex_tex.txt" with no success.
If I didn't see it with my own eyes I wouldn't believe that it was there.
Anyway I am new to C# and obviously am missing something.
Thanks in Advance

what do you mean with the file has no permissions set,
if it has no permissions set it won't be accessible to anybody.
|
|
|
|
|
Not read only, or hidden I meant. My mistake in words.

Are you sure? It really sounds like a permission problem.
Click the Advanced button in the security tab of the file properties. There you can see all permissions for the file.
