Way To Invoke Standard Network Credential Prompt At All?
Jun 29, 2010I'm struggling to find a way of prompting the user for network credentials within a VB.net application. I appreciate I could use the login form, but I'd really like to be able to use the standard Windows UI prompt.I want to use the same credential prompt as you get when you try to access a server using UNC e.g.\servernamec.This is easily possible in Powershell using the get-credential cmdlet. The closest I can find is using the Powershell assembly PSHostUserInterface.PromptForCredential method, but I cant get this to work in VB.netIs there any way to invoke the standard network credential prompt at all?

Remotely Control A Graphical Program Through A Command Prompt
Jun 30, 2011I have created a VB.NET program using windows forms. The program runs on a remote PC and displays information on a screen. The computer does not even have a mouse or keyboard connected to it. The program shows the information based on the file that is loaded.I want to be able to change this file remotely to another file that is already on the remote PC. I can't use a graphical remote desktop client as we have very limited bandwidth.So, my idea is to change the file using the command prompt.I'm not sure how to do this. Should I use something like this and load DosModule first:[code]How would I then read commands that is send to the program? I also only want one instance of the program running.

View 1 RepliesInvoke UI From Separate Thread Does Not Invoke
Oct 13, 2010We have a UI with a progressbar. I know how to invoke, safely, the control from which it was not created from a thread. there are threads being processed in a threadpool, all of which calls an "agent" (which is a notifier to raise an event back to the UI to then increase the progressbar). an "agent" is set as a property in a State object, which is then passed into a method which will be executed on the ThreadPool. so, I invoke on the UI the method to update the progressbar, but the bar does not seem to update at all (screen frozen) and it takes a very very long time for it to execute. without threading, no problem.

Use A Button (A) To Launch A Prompt Where User Selects Directory Path To An Executable Program?
Aug 27, 2011It's probably the most basic of things, but all I can find is how to launch a program, and not with the interactions I desire. Any tips as to the terms to use to search for answers, or links to topics regarding questions similar to mine, would be very appreciated. I have a wealth of info to read through, but I could use your knowledge to save myself time.Here is what I am trying to do:
Use a Button (A) to Launch a Prompt where User Selects Directory Path to an executable Program. The Selection is to be Persistent after the initial selection (saved in a settings file i assume?), and the Selected Path (or just "programname.exe") is to be Displayed in a Text Field (B). Launch Selected and Indicated Program via a Launch Button (C)

Invoke A Method Rather Than A Control?
Aug 20, 20091. On the main form a scanner class is instantiated that (in the scanner's constructor) sets the scanner settings (baud rate, parity, etc) and opens the scanner for use
2. A barcode is scanned (via a scanner connected to the device in a seral port) while on the main form
3. In the scanner class, the DataRecieved event gets the needed info from the scanned code.
4. Then that info is passed back to the main form to a method RunCommandCode (which takes the scanned info as an argument)
5. On the main form the RunCommandCode calls another method CommandCodeHandler, passing the scanned info again
6. In the CommandCodeHandler sub a method is called in a Utils class (SetSelectedTab), which interacts with the form itself (determines how many tabs exist on a tab control), which is the reason for the invoke in the first place
So, before I figured out I needed to use the Invoke method (and, more specifically, that the scanner was working in a different thread), I was getting an error in step 6 on the line that got the TabControl.TabPages.Count.
