I am writing a program that loads a web page then get data from the page for calculations. I can navigate to the web page but the code does not wait for the page to completely load before proceeding. I need a way to have the program wait for the page to load before proceeding.
View 2 Repliesi'm trying to make the program wait while the webbrowser document frame loads. I'm using the code below, but all that happens is the page load pauses while the do loop happens (which obviously will be neverending as the search function searches for a line of html particularly present in the page i'm waiting for the webbrowser to load).

I am venturing into WPF - first time in (VB).NET - and trying to re-create a project I started in MS Access VBA. It basically scrapes a series of pages within a web application. As you may have surmised I am having trouble with the LoadCompleted event.I have searched and found some information on it, but the "flow" of the code only lends itself to waiting for one page to load.url...All of the code execution is run in the DocumentLoaded event which works fine when you just need to navigate to one page and execute code. But I need to perform a series of these cycles for my application. How can I reliably wait for the document to fully load while still keeping the code execution in the same Sub AND not locking the UI thread? [code]That's it. Repeat for n times. my interactions with each DOM are significantly different.

I am trying to load a webpage into a web browser control that has a login form on it. What I am wondering is how I would go about changing the username/password input values on that page thru program code. The html element ids are "username" and "password" respectively.

I have a problem with an App I am writing that lists information about various media on your computer and lets you launch it right from the app. My problem is, when launching an intensive process, like a game for instance, it is desirable to shut down the app to not hog precious resources. Here is the code i have so far...

This code works fine, but for one small detail. The app exits before the desired process starts, thus cancelling out the process all together. My question is, how do I get the app to wait for the process to start before exiting?

View 1 RepliesWhat is the proper way to call up a form and wait until it receives a replay before moving onto the next code step? [Code] Now lf is the login form that waits for the users password and then, depending on if its correct or not when they hit OK it should send back a true or false (isLogedIn). Currently i do not know how to have the code wait until it receives something from the login form before moving onto the next code.
If i use my old code here:
Do Until isLogedIn = True
isLogedIn = isLogedIn
intX = intX + 1
Loop
It never ends if the user puts in a false login password so it just keeps waiting.
I am trying to use a separate thread to handle specific events in VB.Net. The idea being that I do not want the main application to be held up if a particular event handler takes awhile to finish. How do I get my main thread loop to suspend the thread while allowing it to handle events when they occur?When I create a Windows Forms application, there is a UI thread that handles the UI events. I do not imagine that this thread is continuously polling some variable to see if someone has pressed a button. I imagine the thread is suspended until the OS tells it there is something to do. I was trying to figure out how to ensure that my event handlers were not being executed by the UI thread. From what I have read, I can do this by raising the events from a different thread. But what does that thread do while it is waiting for other events, just exit?
I wanted to know how to create a thread that works like the UI thread, only it processes the events I want it to process. I am not sure how events work in .Net. I understand that event handlers are run on the thread that raises the event. I believe that .Net allocates threads from some thread pool to process events such as timer events. I am not clear on how it works, though, and what those threads are doing when they are not handling events.
