I am trying to access a browser control in one of my forms from a module but keep getting an error. I attached a screen capture showing the code and the error balloon. The subroutine is public, and I am addressing the browser correctly. If I copy that same code into the "Main" form, and it works perfectly.

View 10 RepliesI was a vb6 user, done a few projects only with forums Now i am moving to vb.net(vb2010) and i have some trouble.Lets say we have a form(form1), a module(mod1) and a textbox on the form1.
i want to start a Sub (DoWork) in the module but in a new thread.
Dim Thread1 As System.Threading.Thread
Thread1 = New Threading.Thread(AddressOf mod1.DoWork)
Thread1.Start()
The DoWork sub does some stuff and when it's finished i want to change the text of a textbox1 in the main form and start another sub (DoWork2) on the main form under the main thread not the one DoWork is running under.
Plese do not refer me to another post that mighe give me a part answer, try to explain to me what i have to do and why.
I have a dynamically created CheckBoxList in a DotNetNuke module I'm building. When DNN creates the page, it prepends the control name with the moduleID and moduleName.
So, when I have "AddLicenseCheckBoxList" on the page, it becomes:
"dnn_ctr949_addRateGroup_AddLicenseCheckBoxList" depending on what the ModuleID and page name is (in this instance it's 949 and addRateGroup respectively). Now, I don't know what the name of the page or moduleID will be when this module is finished, so I need to make sure I am accessing the control my whateer name DNN gives it, and getElementById or getElementByName do not work even when using '<%= %>'.
So what I need to do is use Javascript or some VB to retrieve the checked values of the dynamically created CheckBoxList so that I can run an update on the database with those selected values. [code]...
In my program, when the user clicks a button, a new tab is added to my tabpage and a WebBrowser is added to the tab. I want to be able to access the WebBrowser in the tab without having to give it a name when I add it.
View 3 RepliesI am writing a program that will search the hard drive for particular files. Once it's done, I'd like the results to display like a folder. For example: If I looked for log files in c: and c:Windows, I would want to put those files in a 'virtual directory' and be able to manipulate them -- as you would in Windows Explorer.
The only thing I can think of that is similar is the search companion, but this software must be compatible with Windows 7.
I know it is possible to display a real folder (i.e. c:windows) in the webbrowser control, but can you have your own virtual directory and only view files that you want in it?
I know how to InvokeScript so my VB form can call a javascript function in the Webbrowser document, but does anyoe know how to do it the other way round - ie javascript calling a vb function in the containing form? Why do I want to do this? Well I've got a table of telephone conversations. Some conversations are longer than others and they look silly in a grid with fixed row height. So I put them in an html document and display them in the webbrowser control. There's a hyperlink on each subject title, and I'd like the hyperlink to open an 'edit conversation' dialog box in my app.

I am having one heck of an issue with a webbrowser control I am using. As part of my job, I am working on creating a tool to automate an older system that we still use. The part that is being automated is web-based, and the group running the automation does not have access to any automation tools like QTP. In order to give them something they can use, the idea was to build an application just for them. In this application, I have everything working perfectly, with the exception of the most important part: the entry of a policy number. The policy number goes into a textbox, and then the user presses a button. A part of the automation sequence involves the use of a timer.
If I manually navigate to the appropriate page and put the .SetAttribute statement in a button action on my form, it works perfectly fine. However, if I put the .SetAttribute statement anywhere that is being controlled by the timer ticking, it does not work.So, this works:
Private Sub btnTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
Me.wbPrestige.Document.Window.Frames("WORKSPACE").Document.GetElementById("policynumber").SetAttribute("value", "1234567")
End Sub
but this does not:
Private Sub timerLoad_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles timerLoad.Tick
Select Case currentStatus
Case Status.wait_for_retrieving
[code]....
As a note, I do not have the Select statement in the Tick action; I have it in its own little sub. However, since it functions the same way no matter where it is, and to save space, I combined everything here. Also, at the time of the timer firing and setting things into motion to enter the policy number, the page is already fully loaded, so I don't think it is an issue with that, though I could be wrong.
It does not throw an error. The "1234567" above is passed in as a string, and doing a watch on it at run-time does show that the value is actually in there. It just seems like the .SetAttribute is not registering on the textbox. I have tried a few things ranging from "what-if" all the way to "that-is-so-dumb-it-just-might-work." Nothing seems to do the trick. I have tried sleeping everything for a few seconds just to see if there was an issue there. I have tried issuing the .SetAttribute command a few times in a row thinking it just wasn't taking the first time. Since setting .Focus() didn't seem to work for it, I even went so far as using SendKeys to move focus to the textbox on one attempt and API calls for mouse clicks (to click inside of the textbox) on another attempt. As a last crazy attempt, I had the Select statement doing a .PerformClick on btnTest (which works if I navigate to the page manually).
But why can't I figure out how to get one of any number of created WebBrowser controls to navigate to a website?I have a FORM a BUTTON and TWO TEXTBOX controls at design time. I run the program and it creates a random number of WEBBROWSER controls named WebBrowser1 to WebBrowser whatever.textbox1.text = a number, 1 - max number of created webbrowsers, determined in whatever way it is. but what if textbox1.text could equal 35, or 1, or whatever. HOW DO I REFERENCE IT'S ASSOCIATED WEBBROWSER CONTROL?!?!?I've spent a few hours researching this and I find page after page on creating controls, but I can't change the data of a control determined at run time, and I can't find how to anywhere.

View 2 RepliesIf a "web page" is more of a "Web App", meaning it is more of an "application" in a web browser, is it still possible to fill forms and stuff? I have come across a pretty huge hurdle in my fight for automation and it involves filling in a "service ticket" submission thing that is browser-based. I can view the source code of the page, but it doesn't look like normal HTML and the first screen of it has a username and password box, but there is no mention of either in the page's source code.

View 2 RepliesI have been trying to use the WebBrowser control to access a website, nothing fancy involved, just a Security Certificate error message I can't get around:
The site that I've been trying to access is [URL].. By clicking on the "Login" hyperlink you are taken to a https connection.Internet Explorer simply allows you to click on the "Continue to this website (not recommended)" link which displays the Logon screen.Clicking on the same link in a WebBrowser control simply reloads the page as (I assume) WebBrowser has not been told that the page is ok.
I've tried looking around for the solution with no luck, it seems like such a simple problem..
I have a webbrowser control on a form and try to navigate to one specific site. It seems to me that the remote detects that call is from a desktop program and redirect it. Is it possible? and if it is how I can hide it.
View 1 RepliesI cannot seem to successfully send the Enter key to a webbrowser control using .net. I can succesfully send postmessage Tab key and it tabs through the links and controls, but it does not click on the link when I send Enter key.The website I am opening has frames, and due to the cross frame scripting policies microsoft forced into the IE control , I cannot retrieve the links from the IFRAMES on the page. So my alternative thinking is to use Tab keys to get to the link and then press Enter.

I created a Windows Form application that used a Webrowser control to automate the process of entering data into a website. One of the tasks included selecting a server name from a dropdown menu (SELECT tag). I was able to get a collection of all of the OPTION tags and use HTMLElement.SetAttribute("selectedIndex","indexVal ue") to select the server I needed.The website recently went through a redesign and now there are no OPTION tags. It appears that the values for the SELECT tags are added by JavaScript dynamically. I have tried using HTMLElement.SetAttribute("selectedIndex","indexVal ue") directly, but I am unable to select what I need.
