• Visual C++ Telnet code in C++

  Hello, I am trying to modify an existing piece of telnet code. I have modified the 2 of the existing functions in the code and added one new function (filter function to perform the IAC filtering). The two functions read and connect are the ones I tried to modify. I tried running the application after the changes and it gave me a memory mishandled error. The code is as follows: int CTelnetClient::Read(char *data, int maxlen) { // check how many data are ready DWORD readydata=0; int nbyteread; int filter = 0; IOCtl( FIONREAD, &readydata ); //there is a seperate function that is waiting for data. if( !readydata ) return( 0 ); // read the data memset( data, 0, maxlen ); if( readydata<maxlen ) maxlen = re ...Show All

• .NET Development HttpWebrequest Post

  Hello Im trying to upload a file to a https address using the getRequestStream method of the httpWebRequest class. The code appears to work fine and no exceptions are thrown, but the file does not appear to have uploaded to the server. The stream is working as it should. The server requires authentification via a public key, which i have and is installed. I have used the CreateFromCertFile method of the X509Certificate to add the certificate to the WebRequests client certificates. I belive this method extracts the public key from the certificate If I try and call the GetResponse method, an exception is thrown - The remote server returned an error : (401) Unauthorized.

• Visual Studio Express Editions Formulas like excel

  Can anyone tell me how a program like excel handles formulas. From what i can see it looks like it stores the formulas somewhere away from the database. How does this work Or am i even close Can someone tell me how to create something similar if i wanted to store the value in a particular cell, how would i do that Dim cell1 as integer cell1=Me.MaintableDataGridView.Rows(0).Cells(0).value or would i use .formatted value instead of .value What i am after is a way to do something similar without having to declare every single cell. I would have to declare approximately 40,000 cells. ...Show All

• Visual Basic Do nothing in a while loop

  I have a while loop that runs until one of two conditions are met. 1) A timer elapsed 2) A COM object raises a event that is done doing a task This works great but while the program, it's a window service, is running, it utilizes 50% of my CPU power. How can I make the service do nothing when it's in the while loop My code: With Timer1 .Interval = maxTime * 1000 .Enabled = True Dim i As Integer Do While Not ReadyState And .Enabled i = i + 1 Loop .Enabled = False End With that is bad design. It will take up the CPU as you have mentioned because there is nothing to do/its going fast in the loop. you can add a Thread.Sleep(200) to sleep the threa ...Show All

• Visual Studio 2008 (Pre-release) Repeating controls

  Hello all, I was wondering if there was any way to repeat a row of controls Say I have 2 ListBoxes, 2 Radio buttons, and an Edit box in a row, and I need 6-7 such rows. Right now I create one such row, and copy paste it, and change the Name attributes. This really bloats the Xaml. I could use a ListBox and use that to repeat the rows by style-ing the ListBoxItem appropriately. But is that the way to do it Would there be such sort of native repeater control in WPF Something like the one in ASP.NET An alternative is to use procedural code - but I am consciously trying to avoid doing that. After all, Xaml wasn't introduced for nothing - might as well try and utilize its capabilities to the maximum, eh :-) Thanks in advance. ...Show All
