Can't Access Web Page Forms
Mar 14, 2011
Seems like something is preventing me from accessing forms inside web pages that I visit. When I visit a website like Google.com using my custom VB browser I can't add text to the Google search form or any forms on any web page.So I can't register at web sites. And I can't login or use any form that sits on web pages.What is keeping me from accessing web page forms? I mite be missing some kind of .DLL file on windows XP but I can access forms fine in web browsers like Mozilla FireFox.

I want to access a page variable from a user control placed on that page. All the solutions work in C# via casting to the page class. The problem is that this doesn't work in VB. The page class is not selectable from the Intellisense dialog. Manual typing results in the error type not defined. It is strange that C# can do this without a problem. What is the proper solution for this in VB? I had other cases where I needed to access a control on the main page. C# again uses a cast to the page class to access the control. This doesn't work in VB again. So how can I access the page class from a user control in generell?

I have a program in VB.NET 2005. At some point I have to open an Access2003-Application for getting data in it. I do that by pretending my program is a human user and let it do all the work in Access as a human user would do. Filling Fields, pressing buttons etc. I use the Primary Interop Assemblies for that. So far so good. That code is in use for over half a year now. In the last week I got Office 2007 installed on my machine. Of course I tested the installed version of my program if everthing still works. Every test was succesfull. But if I do the same tests in Visual Studio it always crashes.
All I get is this Errormessage: {"Das COM-Objekt des Typs "Microsoft.Office.Interop.Access.FormClass" kann nicht in den Schnittstellentyp "Microsoft.Office.Interop.Access._Form3" umgewandelt werden. Dieser Vorgang konnte nicht durchgefhrt werden, da der QueryInterface-Aufruf an die COM-Komponente fr die Schnittstelle mit der IID "{66B22FB4-F70E-4F03-A00A-F76E9ADBBF10}" aufgrund des folgenden Fehlers nicht durchgefhrt werden konnte: Schnittstelle nicht untersttzt (Ausnahme von HRESULT: 0x80004002 (E_NOINTERFACE))."}
For all who can't read german:
"Microsoft.Office.Interop.Access.FormClass" can't be converted in to "Microsoft.Office.Interop.Access._Form3" ... Interface is not supported.
Code I use:
Dim access As Microsoft.Office.Interop.Access.Application = Nothing
.
.
.
access = New Microsoft.Office.Interop.Access.Application()
[CODE]...
The Error occurs when I try to access any property of "access.Forms("frmTest")"

I'm writing an atm program. Should I write it to where each page (ie: withdraw, transfer, deposit, etc.) hides the current form and calls another form to show? How do I keep it all in the same form so it doesn't look like I'm closing and opening new forms?

Does anyone know if it's possible to have a tab page, on a tab control, with a smaller area than other tab pages on the tab control.
For example, if the small tab was in focus, the contents of the tab behind would be visible.
I have tried the tab page size properties, this doesn't work.

I have an ASP.Net site that is using the singular form model. Each page has multiple forms (login, search), and I'd like for the forms to obey the 'enter' key. Currently if a user is in the login form at the top of the page, if they hit 'enter' the form is submitted, but if they are in the search form, a little further down the page (and lower in the DOM), hitting 'enter' causes the login form to submit.

I have a question about web forms. I've set up a web service and I'm now trying to make a registration page. The one thing I couldn't figure out is how to handle events. For example, I have a simple button with id="Register", how can I handle that event? I can't seem to call a textbox on my form like you usually do in a VB form.

I have an asp.net web forms application that uses asp.net membership and URL Routing.Because of the way Roles work, i cant put an "AND" or "OR", etc. in the allow/deny tags of the web.config file that resides in each folder.This is a business website that that is being ported from a vb.net win forms project that contianed many apps. (The win forms project have a custom authentication system.)The web app is structured in a way to mimic the desktop suites and a folder was created for each app.There are also common folders where any user of any app can generate a report.

Using Access I created a few Data Access Pages. These web pages, once opened, work fine to manipulate data as intended, but they keep generating annoying warning messages.There are two messages that pop up every time the web page is accessed. Before the page opens the first message that pops up states: "This website uses a data provider that may be unsafe. If you trust the website, click OK, otherwise click cancel."After pressing OK on the first, the second message pops up and states:"This website is using your identity to access a data source. If you trust the website, click OK, otherwise click cancel."After pressing OK on both messages the page functionality works just fine.I've tried adding password protection to the database and even signing the project with a digital certificate, but I still get the warning messages. This would be fine except there are multiple end users for the access pages and I am trying to avoid the additional confusion this will create, especially since IT has restricted many of the users from editing the internet options.

I'm working on a pretty simple project, just a WebBrowser app which is tailored for Webmail. I'm working on an OWA portion, and OWA normally doesn't allow the textfields on the Login page to be auto-filled. Is there a way I can force this? Search through the OWA login page code, find the fields, then fill in the fields with preset/saved data?

Access objects on a dynamically created UserControl an a dynamically created tab page. I can usually find the answers to most of my questions via the Google Gods, but not this time. I hope the collective that is StackOverFlow can help! I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection, all good so far. I can't get my head around how to access the objects on the newly created tabpage. What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it! [Code]

I have a huge website (containing around 5000+) pages. There is a theme functionality in the website where user can choose different colors for their profile. Now i want to use the ASP.net theme feature and put different CSS (for different colors) in the theme folder and in Global.asax i want check the user theme and render appropriate link element with the css. But my problem is, i am not able to access the Page element for adding the link in the page. Here is my code
Dim page As System.Web.UI.Page = TryCast(System.Web.HttpContext.Current.Handler,System.Web.UI.Page)
page.StyleSheetTheme = "Black"
But when i run this code I get a Null reference error.
P.s : My application is very huge so its not possible to have a master page or a base class and inherit it in every page.

There is a site that I go to that has a website chat thats located at the bottom of every page. It allows you to talk to specific people while you're online and they're online.
Sometimes when I get into a good conversation I don't want to end it. I still have other things to do though.I wanted to make a small window that I can just drag around that will allow me to chat with people easier.
I've set up pretty much everything in this program except the actual retrieving of the information from the site and the replying to the chat. I know I could do this (I've done similar things in the past) by putting an invisible webbrowser object off to the side and just run my stuff through there. But I think thats kind of sloppy.
I've read in some of my classes and books and have learned how to make simple web requests that return the results. In its case, I had to return definitions from google. I tried this on a recent project but found that it didn't the permission to access any kind of secured account whether it was logged in or not because it was "unsafe".
Does anybody know how to access a page thats been logged into through IE but without needing the sloppy methods I mentioned earlier?

I have a site where users must only be able to access the Login.aspx page via SSL/HTTPS.Currently I run something like the following in my Page_Load():
If Not (IsSSL) Then
Response.Redirect("https://" + thisDomainName + "/Login.aspx")
End If
Is there a better way of doing this?
