Web Browser Control Working Offline - (Cached Web Pages) Only?
Aug 18, 2011
Is there a way to work the web browser control for viewing off-line (Cached web pages) only? Is it possible to view cached web pages from IE9 on a web browser control off-line? The reason i am asking this question is because IE9 automatically switches from off-line mode to on-line mode when it cannot find something in the cache by default. For forensic purposes this is not acceptable for these reasons: Active content (Viruses, java script, activex cookies etc)

We have a issue with laptops for the current client in which IE continually shows prompts to users about working offline. The laptops are on a flaky wireless connection (Personally I would much rather fix this but they would much rather just fix this issue, apparently this works better money wise. I have my doubts).
Anyway the issue I'm facing is removing this box from opening at all.. Now there are two ways I can think of doing this. A possible Hook if it is available to catch it before it comes out and stop it. Or the less nice way is to when the box comes up to automatically hit the "try again" option using a sendkeys push.

I am working on an application and I need urgent help. One of my forms contains a web browser. I need to detect if F3 key is pressed while the web browser is active, so a dialog box will appear for a particular functionality of the application. But unfortunately web browser control does not have keyup, keydown or similar event to help me detect if the F3 key is pressed. As far as I know, one way to solve this problem is adding a menu which has F3 shortcut. But my application does not contain any menus, so I dont want use a menu in this part of the application.

My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?

i'm making an app which uses a webbrowser control to show some offline (not cache) html pages like a slide show. let's say pages in a folder on the desktop etc when it came to testing the whole thing, i figured out that the images in the html are not visible on the webbrowser control. instead there is a space where the image should be, corresponding the actual image dimensions.and when i right click on this empty space where images should be, and click on properties, i see the image size given as -1 byte (minus 1 byte) and there is no image type.
however given any online url's to the same webbrowser control or opening the same html pages with the real internet explorer i got no problem and see the images.i've been googling for almost 10 hours for a solution without success, so any hints are welcome. used vb 2008, .net framework 3.5, ie 7.

I have code/support an application built on .NET framework that has always run on .NET 2. This year we are upgrading the application to use .NET 3.5 (or 4?). In preparing for this change we noticed that that Offline Installer (required for our customer base) for .NET 3.5 is 200+ MBs bigger than the .NET 4 offline installer.
Here are my questions.Why is the dotnet 3.5 installer so much bigger than the 4 offline installer?
Can we TARGET .NET 3.5 but distribute .NET 4. In other words, is .NET 4 backwards compatible? Assuming that .NET 4 was the only installed .NET could application still target earlier frameworks?
IF our application is compiled for x86 CPU (rather than Any CPU) do you still have to distribute the x64/x86 Client Profile or can we just distribute the x86 Client Profile? In other words, can we distribute the x86 Client Profile even though it will be installed on x64 machines if our app is compiled for x86 target CPU? Any risks or gotchas for doing this?
The issue is that if we upgrade our app to target .NET 4 there are a lot of application servers that we also have to upgrade which effects a number of other applications.

I want to create a UI that uses a tab control to display multiple listview controls, one on each tab page. The number of tab pages/listviews is dynamic and could reach around 20. The listviews are in virtual mode and are populated from an object (custom class) in memory.It seems very wasteful to create 20 listviews. I seem to remember that back in VB4 days the tab control had only one page, and you changed the display yourself in code. Is there a way to do something similar with VB.net (VS2008/Framework 2.0) i.e. just show one listview and repopulate it according to which tab was clicked by the user? Something like this:
Private Sub Tab_Click
listview.load(MyObject(TabClickedIndex))
End Sub

I know this topic has been discussed here before, but I haven't found any secure, clear & easy solution.
I can use a commercial solution (if price is ok: I only want it for this feature, not a bloated control with hundreds of pdf functions).

I need to change which pages of a tab control are available at different times. Right now I'm just disabling the unwanted tabs (TabControl1.TabPages(x).Enabled = False), but I've got a user who can't comprehend why she can still view the tab page if she can't use it.
So I need to either hide the tabs altogether or disable them such that you can't switch to that tab page at all.

I've created a tab control and on one of the pages I added a button, but I cannot move the button around with the mouse!? I can change the buttons position within the tab control page using the property Location and I can size the button using the mouse and the button is NOT locked. I even tried creating a new project with just the tab control and it still does the same thing. I can, tho, move the button using the keyboard arrows!
I'm using VS2010 V10.0.30319.1 RTMREL on WinXP SP3.

I am still relatively new to the .NET language , but I will get straight to the point. I have a web bowser i have made after 2 nights of coding and getting myself familiar with it. I have a menustrip at teh top, with a view category. Inside taht category i have a view cookies and view history button. As we know, ths browser stores its history and cookies with the Internet explorer. I am looking on how to create a form with the ability to view history, and another to view cookies. I also want to be able to delete them willingly from within the form. I have a listview control already on the form, but i am lost elsewheres.

I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer
Pages = New Integer() {1, 3}
PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.

Here is a setting called PopUpBlockerEnabled:And here is my Addhandler code when the browser is being created on form1_load:
AddHandler Browser.ProgressChanged, AddressOf Loading
AddHandler Browser.DocumentCompleted, AddressOf Done
If My.Settings.PopUpBlockerEnabled = True Then AddHandler Browser.DocumentCompleted, AddressOf BlockPopUps
(By the way the setting PopUpBlockerEnabled is true or false when a checkbox is checked)ok so here is my private sub BlockPopUps code:
Private Sub BlockPopUps(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs)
e.Cancel = True
MsgBox("PopUp Blocked")
End Sub
And when i test the popup blocker on this site all the popups show without a single popup being blocked:[URL]

I have an ASP.NET page with a Wizard control containing several pages of form fields. The data is collected and inserted to a database from the code behind page. I need to set this form up so you can not only insert, but edit a record as well. Since the form is long and complex, I would rather use the existing one and not make a duplicate one for editing, especially since I want to keep both forms exactly the same and any edits would have to be made to both. But it looks like this is what I need to do if I'm going to databind it. But this would also involve putting the Wizard inside of a FormView, and then I'd have to use FindControl to access any of the fields which would mean altering all my already-existing code (which of course would be time-consuming). So should I manually enter all the values from the code behind instead of databinding it? Which is better, to use a FormView and have duplicate forms (plus have to go in and redo the way I access the fields), or to do everything from the code behind?

I am trying to use the Web Browser control in my vb .net user control. I am using VS 2008. Finally, I will be calling my assembly (.dll) from a web page. I wanted to display the usercontrol with the web browser control inside this web page. The problem is I cannot proceed since the Web browser control cannot be called from a partially trusted assembly. Using VS 2008 I have created a strong name for my class, also added the <Assembly: AllowPartiallyTrustedCallers()> to the AssemblyInfo. But still the web browser control cannot be seen in my web page. Do you how I can make my assembly fully trusted so that it can access web browser control? If you have used web browser control, can you confirm if this step is really required?!

I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:

I have heard of setting server specs to have HTML pages parsed as PHP pages by changing the .htaccess or httpd.conf files. Is there a similar solution to have HTML pages parsed as ASPX pages?
A website I am working on does not want their PageRank to lower since their HTML pages are already indexed and used on other websites but wants to use some dynamic features of aspx pages (like include the navigation file so that changes to the nav will only have to be done in that one file).
