Login And Navigate Website?
Feb 3, 2011I am new to VB, and I am using Visual basic 2010 Express to make an application that will login and navigate a website for me. On a form, i made a button and a webbrowser, and this is the code i have so far:
Public Class Form1
Dim Automate As Boolean
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Automate = True
[Code]...
The last line of my code that nagivates to a new page after login... it executes before the login completes and the login fails. If i remove that line of code, the login works fine. So how do I navigate to further pages after the initial one, and make sure that it is fully loaded each time?
Navigate To A Website And Then Get The Element By <br>
Feb 14, 2011I have an app that I am trying to navigate to a website and then get the element by <br>.
I'm thinking that I can get the element by using this code.
Dim allelements As System.Windows.Forms.HtmlElementCollection = WebBrowser1.Document.All
For Each webpageelement As HtmlElement In allelements
[Code]....
My issue is how can I take all those elements and add them to a rich text box on my app?
There is also about 3 pages that I am needing to navigate to and download the content on, is there a way to add to the list until the loop is finished?

View 2 RepliesAutomate A Process - Open A Website And Navigate Through It - Enter File Name And Path - Not Populate The Text
Feb 2, 2009I am trying to automate a process I do with a bank with vb.net. Basically I need to open a website and navigate through it (Automatically through the program obviously), enter a batch ID and enter a file path and name. For some reason when I get to the part where I need to enter the file name and path, it simply will not populate the text. I have attached a word document with screenshots and code. The only difference I can see, is that in the bank website's code the the input type for the file text is "FILE" rather than "TEXT" as it is for the batch id...

Get The Flickering To Stop?
Oct 24, 2011I have read everything I can find, and understand some of it. I don't know what I am missing though. I can't get the flickering to stop. Can anyone help me? I've been using VB 2008 for months now, but I am new to the graphics bit. At first I tried using an ellipse from the powerpack, but that flickered even worse.

Tab Header Flickering?
Dec 6, 2010I am working with GDI+ to draw backgrounds for my forms. I have a main form with 4 tabs, which all flicker. There is a gradient background behind them (bitmap drawn in GDI+ at Form_Load). I have double buffering enabled in the following manner:
Me.SetStyle(ControlStyles.UserPaint Or ControlStyles.AllPaintingInWmPaint Or ControlStyles.OptimizedDoubleBuffer Or ControlStyles.ResizeRedraw, True)
Everything on the form rarely flickers. The only times are when I am resizing, the numerous docked controls on my piece-o-junk netbook flicker momentarily, which is hardly noticeable. On a normal laptop it runs quite smoothly.The problem of which I speak is right on the headers of each tab (the white rectangle with text on it). When I move my cursor on or off of it, it will flicker. What is actually happening is that it is momentarily disappearing then re-appearing. This seems to be a control paint bug.I've tried the following override, without success.
Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
Get
Dim cp As CreateParams = MyBase.CreateParams

Comboboxes Flickering On Populating?
May 27, 2009I have a combo box on a form, it has a large number of values in it (about 40000).

Image Doublebuffer Flickering?
May 18, 2010I have a form where i put controls at runtime. Everything works fine and fast. I also set the doublebuffer property of the controls to true and then there is no flickering at all. But then i proceed to add an image in the background (also during runtime), but then each item i move is flickering even if i remove all the controls and only leave the background image when i move another form it flickers anyway.I put an example below of how im adding the image.

.net - Reorder Tabs In TabControl Without Flickering
Dec 17, 2010There are multiple examples of modified TabControls on the Internet which allow the user to reorder the tabs using drag and drop. However, all seem to use the following technique:
Determine which tab is being dragged
Determine the index to which the tab is being dragged
Empty the tab page collection and add in the new order
The last step, hoewever, causes the control to flicker alot. Besides this, when there are a lot of tab pages on the tab control, it is rather slow.
Is it possible to swap items (i.e. swap indexes) in a TabPageCollection, without the TabControl flickering?

View 4 RepliesRemoving Flickering Without Double-Buffering?
Feb 22, 2011I am having a similar issue with the double buffered set to true for a picturebox. I customized a picturebox control in vb.net where, a panel contains the picturebox.
Upon a mousedoubleclick of the picturebox, i scale the picturebox width wise a certain scalefactor, so that the picturebox is greater than the size of the panel. I am doing this for horizontal zooming and panning. With that said, the picturebox could become large in size.
At certain screensizes, after scaling the picturebox 6 times the size of panel, at fullscreen, i receive an error messsage implying "Not enough memory available to process the command."
However, when i turn off double buffered, i dont get the error, but i get much unwanted flickering.
Here is my code in the Paint Event:
Private Sub picPMGraph_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles picPMGraph.Paint

View 7 RepliesControls Flickering Due To Background Image Of Panel?
Mar 5, 2012i have developed a windows application whose interface has multiple picture boxes panels with background images for rich look and also a usercontrol which contains a gridview and WPF scrollbar in an element host. All these controls are placed in one panel (this is also having a background image) which is equal to the size of windows form. The reason for placing all these controls in the panel is that the window can be resized, if needed, allowing scrollbars.
Due to these large number of controls in which some of them have transparent backgrounds loaded in a large panel having background image, the window is flickering when moved or any other application's window is moved over it.
