• .NET Development Connecting to a telnet server

  Basically what i want to do is make my program connect to an existing telnet server, put in a username and password, wait til it receives a prompt then run a command and grab the next lines for me to parse and use. If anyone can point me in the direction of a good tutorial on the best ways to achieve this that would be great Martin, I was able to use this library located in the downladable source code to assist me in scripting my telnet session.

• SQL Server Time Series only predicts one step

  I have a relational table with daily sales for 364 days (52 week span) for 60 stores. I have created a Microsoft Time Series model using store as the case and the historical/actual line charts appear in the Charts viewer for each store. But only one prediction step is shown no matter how many prediction steps I select. I have tried this with an OLAP-based model and also tried a simple DMX query, all with the same result. Thank you in advance for any help with this. P Taylor Jamie, I have e-mailed a CSV file to you, of data that I have been using. Many thanks Philip Taylor ...Show All

• .NET Development Query regarding calling serial ports in C#!!!

  Hi, I am porting an application written in C to C#. It includes Serial Comm. with the comms tty device (Serial Port).

I need to map the corresponding port settings (MARKED IN RED) in my C# code . Please find below the code written in C.. // open tty port for connection to LSA P_clock_lsa_fd=open(LSA_CHANNEL_DEVICE, O_RDWR|O_NDELAY|O_NOCTTY|O_NSHARE); // make an ioctl call to obtain device details in // the termio structure tbuf if ( ioctl (P_clock_lsa_fd, TCGETA, & tbuf )==-1) { // failed to ob ...Show All

• Visual Studio Express Editions keyboard characters

  How do i make a subroutine for a certain character on the keyboard. e.g. Private sub keyBtnA_Press(byval etc) xyz End sub you need to explain a bit more on what you need it for in order to help better. However lets give it a shot. Implement the keypress event for the textbox in question (click on textbox in designer view, select the events icon which is the lightning symbol and double click the keypress event). Then check the key pressed, depending on the key pressed then do your thing, such as call another subroutine or something. Example:   private sub TextBox1_KeyPress(byval sender as object, byval e as KeyPressEventArgs) handles TextBox1.KeyPress    Me.DoCheckKey(e.KeyChar) end sub   pr ...Show All

• Windows Forms Help in implementation of a magnifying glass

  I have an image viewer application which I want to apply a magnifying glass effect on certain area of the image. The problem I've run into is that when I slowly dragged the magnifying glass across (when left mouse down) the magnifying glass window didn't move smoothly. I believe it has something to do with drawing the graphics of the original image on the background. May someone please help me solve this issue Thanks. This "this.Update()" method call in picPanel_MouseMove() is probably the source of your problem. Invalidate(true) should be good enough. Actually, you shouldn't need anything there; Windows should detect that the moved magnifier window has revealed a portion of picPanel that ought ...Show All

• .NET Development Best Practice for C# App and SQL Connection

  Good evening, I am new to developing application in C# and Visual Studio 2005. I am an ASP guy, so I am finally moving to .net. I am writing a Windows application in C# and I need to use SQL as my backend to check usernames, passwords, and settings. What is the best practice for connecting to SQL for an application that is constantly hitting SQL up for some data In ASP, I open connection, get data (or update) and then close the connection. Is it done the same way in a Windows application in C# Since it is going to be constantly getting information from SQL, I want to write it so it is pretty efficient. I appreciate any feedback.

• .NET Development vb.net and access

  I have set up an access database and am trying to pull data from it. Everything was going fine until I closed out the program and tried to reopen it.
