VS 2010 Refreshing WebBrowser IP?
Oct 15, 2010
I am in need of a method to refresh a webbrowser object's IP address. Until now, I've just change the value in the Registry. However, the webbrowser only gets the IP when it is first instantiated (when it first navigates to a web page). So, it will not update every time I change the registry. I know there is a way to simply change the IP of the webbrowser itself, so that it will update the IP every time the command is run in VB6, however I have no idea how to do this in VB.NET.

1. Is there any way to disable refreshing in such a way that the button can still be used for stuff like flash on the page still? All my methods have blocked using the button in the flash which is loaded on the page....
2. Is there any way to get the new scrollbars of IE10 or metro style scrollbar or what not into the webbrowser like the desktop version of IE10 does in Windows 8 Consumer Preview?
3. Is there any way to allow the close window called from javascript to be detected & actually close the window in my program?
4. Is there any way to make it so when new window is called it will open a new window with my application in a new instance? stopping me now is it seems to want to open in the same window if I use the event NewWindow to cancel the event from happening but it gets script errors....is there any way to retrieve the link to what it needs to open so I can handle this properly? Or at least tell it what else to use? besides the default browser....I want it to open inside my own program & not IE.

It uses a Drawmap() sub with map data to create the map on the game load, but I can't seem to get it to refresh, and then re-draw the map based on player location. For example, if the player walks into a door, then it refreshes the map to show them in a building. Any advice on this? Code below:
Imports System.Drawing
Imports System.Windows.Forms
Public Class Form1

the Datagridview is included in first tabpage. first tabpage is the search form and the second tabpage is the record detail view. user is switching and working between those two continuously.
The problem is that everytime user selects the tabpage1 the datagridview repaints itself. there is about 6000 rows in datagridview so it takes about 2-3 sec to paint itself. I know the delay is normal and can't avoid that. but it affects the tabpage selection. tabpage1 isn't selected completely until the Datagridview1 finishes it job. in this time the tabpage1 and tabpage2 gets combined and confused.
is there a way to put datagridview processing in backgroundworker or something that doesn't affect main UI ?

I'm new to VB programming and I'm trying to develop a program where you browse and select a picture, then it opens in a Picturebox. Afterwards you can choose to open that same picture in paint. My question is, after opening it in paint, making changes to it and saving the picture, how can I make it refresh automatically on the Picturebox with the new changes ? The code I'm using to open my image in paint is the following :

i'm an old VB6 programmer that has just starting dabbling in VB.NET 2010 and my first project is a Usercontrol Button project and i'm running into some trouble with refreshing the usercontrol on events.
For example when you mousedown on the usercontrol i want it to act as if the button is being pressed in, to do this i make the caption move 2 pixels down and to the left. And then reverse this when the usercontrol mouseup is triggered.I think my code is correct but i'm not 100% sure what i'm doing with me.refresh and the usercontrol_paint events.

so I am a little confused. I am trying to refresh my datagrid when I have either add, deleted or edit a row via another form. I have it so my main form shows the datagridview, I have bound my controls to the database and I see all rows, no problem. I also have it setup to double click a row and it brings it up in another form to edit that record. This works. but it doesn't refresh the datagrid when saved. I am trying to follow this thread, specifically this post Refresh Datagridview - Post 2 Here is how I am loading the datagridview in main form

So basically I created Dim gr As System.Drawing.Graphics on my picturebox and I am drawing on it.
Each time I cover my window with anything or move it away from the screen whatever was covered/invisible becomes missing.
As I understand I can do:

I'm trying to make a little app that displays the battery life of a notebook, and also whether it is charging or not.I've got it displaying the battery percentage and if it is running via the cable or battery alone.My problem is that I have a timer constantly ticking to grab the latest information as to whether it is still chraging, what the battery % is like, however for some reason when it first runs it get's the info but then that's it, it won't refresh the info in real time. I'm confused because the battery can deplete but the program only displays what info it got when it was first ran but if I unplug the power cord or plug it back in it refreshes that info straight away. My code is:
Public Class Form1
Dim psBattery As PowerStatus = SystemInformation.PowerStatus
Dim perFull As Single = psBattery.BatteryLifePercent
Dim GraphicPercent As VariantType
[code]....
The bit I've highlighted in red in my code won't work either, basically I've shaped the two labels to look like a crude battery shape and label2's function is to represent the nobly bit at the top of the battery and I wan't that to change to Lime when the battery is 100%.why it won't refresh the graphical output to the screen?

I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?

I've been looking around for a better WebBrowser object, because Internet Explorer won't load half of the pages I need it to. I've found a Firefox OCX control, however I can't figure out how to use it correctly. Is there any way I can embed a Chrome, Opera, or FireFox object in my program instead of using the default Internet Explorer?

I cannot tell you how disappointed I am in the vb.net Web Browser Control. It really seems very ill thought out and rushed.So; to my question! I have searched all over the place in an attempt to find the answer to this and from what I can see alot of individuals are suggesting that it is better to use the old web browser control from VB6. However, i'd like to try to avoid this.

I have a form that uses a tab control. On the main tab is a DataGridView containing Customer information. If I double-click on a row in that DGV, I go to another tab in which I can either make changes or delete the record. Whatever I do, whether it be delete it or modify it, after clicking on the appropriate command button, focus goes back to the main tab. What I wish to do is have the changes be reflected on that DGV. If the record is deleted then I want the DGV to not have that record present. This DGV is bound to a BindingSource. What control/dataset to I need to "Refresh" in order for this to happen?

I have a VB (2008) program that I wrote that will not refresh the info in a textbox. I've tried to refresh, update, hide/show the data but cannot get it to work. Here is a code snippet:[code]The concept of what I'm trying to do is quite simple. the user selects one or more sites to check, the program shells out and SSH's into the device(s), grabs the output an parses the data. It then turns different boxes to different colors based on the output. The maddenign thing is it works for the first time through and sometimes the second, but never any farther.At the end it paints everything just fine and if I insert a blank msgbox within the code it refreshes fine as well.

I have some questions about the Windows.Forms.WebBrowser control.I have added this control to my project to be able to browse websites internally.First problem is that when I come into a webpage that contains JavaScript to open a new window, the control opens a new instance of iexplore.exe, tries to load the page in which the java script popup code initiated, but then prompts for authentication for a second time.Basically, I have to sign into one page to get to a listing of applications.I click on the application which in turn is just a URL to another page.The URL to the other page contains java script to open a new window.The new window opens in an iexplore.exe process, but re-directs me to the original sign in window instead of taking me to the correct site.If I do a msgbox on the cookie that is currently loaded, it displays my authentication information.How do I tell the new iexplore.exe processes to use the cookie that was stored in the webbrowser control?
