• Visual Basic How to use a Process to run CMD and a DOS utility to send Commands

  Hello, I need some help. I want to write a program that will do the following: 1. Start a process that will run CMD.exe 2. Once in CMD window run the DOS utility (i.e., "C:\utility.exe Command) where Command is the command to send to a device. 3. There are about 5 or 6 commands that I need to send to configure a device using this utility. This utility exits with the "quit" command and returns to CMD window. Can this be done using one process or do I need to use two process and how do I go about this TIA for your help. Hi, you could try writing a .bat file and st ...Show All

• Visual Basic What is the best means to FTP files?

  Hello, I am wondering what the best means would be for me to FTP a file using VB. Don't suppose there is a quick easy command that I am missing. Thanks, Aludaan I hope I have some better news for you this time. I don't know whever you are using VS or an Express release but if you are using VS Beta 2 and I hope you are because it's beautful.... There is an FTP example in basic very close to you.

• .NET Development Switch from .NET Remoting 1.1 to 2.0 problem

  Hello, Recently i switched to .NET Remoting 2.0 (before used 1.1) and ran into the problem with something related to lease expiration. With CLR 1.1 all works fine. I override InitializeLifetimeService() method to have unexpired lease time as it is below in snippet code: public override object InitializeLifetimeService() { return null; } But although it exeptions like: Unable to connect to the remote server No connection could be made because the target machine actively refused it ocurr after some interval of time. I didn't change my code so perhaps there is some new tune for 2.0 that should be made to get all this w ...Show All

• Windows Forms UserControl Terminate, Close, Exit, etc.

  Does anyone know of a way to determine when a UserControl is being closed by the user in C# There used to be a Terminate event in VB6 that you could capture. I can't find anything like that for UserControl. UserControls exist on a Form. There is no way to close UserControls. You close the containing Form. Or is that what you're asking How a UserControl can detect when its parent form is being closed If so, the UserControl can just subscribe to its parent's Form.FormClosing event like this: namespace FormCloseCapture { public partial class UserControl1 : UserControl { public UserControl1() { InitializeComponent(); ...Show All

• Windows Forms Treeview Drag-n-Drop

  I've got a treeview control that accepts a filedrop from Windows Explorer. The drag and drop events work fine except that when I drag the file over the treeview it does not highlight the nodes as I mode over them. Therefore the only way to add a file via drag and drop is to select the node first then goto explorer and drag the file over the treeview control. I've tried enabling HotTracking on the treeview in the dragenter event, but it makes no difference. Hottracking is the auto-selection of a node when the cursor hangs over it. However for this to work the treeview has to have access to the mouse. With ...Show All

• .NET Development GUI thread, memory leak and Garbage collection

  Hi all, I seem to be chewing up memory at a nasty rate when my app runs. It has a polling loop and not surprisingly this is the part that keeps doing it. I think I've located the line that is my main offender and its when I marshal to get back onto the GUI thread so I can update my controls. private void KPI_ScreenUpdate( KPI KPIType) { if ( this .InvokeRequired) this .Invoke( new KPI_ScreenUpdateDelegate (KPI_ScreenUpdate), new object [] { KPIType }); else { DPL_Units_Through.Value = myKPI_Shift.Units_Through; DPL_Shift_Time.Value = tmpElapsed.ToString(); // blah blah ...Show All

• Visual Basic Efficient Threading

  Guys, Creating an app that's essentially a Telnet server. At the moment, I've got two threads: 1) Listens for connections and accepts them 2) Checks to see if any clients have sent data that is waiting to be read. Is that enough for a basic Telnet server, considering that I may have up to 2000 connections online at once Or should I have a thread for each client Cheers, everybody! Will WIll everyone here is not a guy. There is an advanced technique called connection pooling You don't keep 2000 connections you create just enough connections to handle what is actually transpiring at the moment. ...Show All
