I am writing a windows form application, where I want to have a WebBrowser control, and in that control, I want to show a Google map programmatically generated (I mean, not just specify a URL to the browser).
View 1 RepliesI am trying to render a hyperlink to html. ( etc)
When the page loads it works fine. (and lots 10 links) on the update panel it hits the same function and tries to get another 10 links. I set the navigationURL to something like
"../Folder/Mypage.aspx?498592ghjgfosdfgo"
It is set identically both times(load and updatepanel postback) but when i try to render it to html the second time (on the update panel) it adds "../" to the front so i end up with
"../../Folder/Mypage.aspx?498592ghjgfosdfgo"
The function where it changes here
Public Shared Function RenderControl(ByVal c As Control) As String
Dim sw As New IO.StringWriter
Dim htmlw As New HtmlTextWriter(sw)
[Code]....
This problem is with the WebBrowser component. The code posted below is what I am trying to insert into the control before it renders the page for the first time. This question actually stems from this post: [URL]. I am developing the application in C#, however the problem is not really language specific.
When I have a page that has a javascript call to:
window.print()
I am wanting to override the print method so that pages do not pop up the print dialog. I can do so by inserting this into the top of the html:
window.print=function emptyMethod() {};
I now just need to figure out how to get this code into the document html before the browser control renders it for the first time. I have tried a number of things (for a complete list, see the post listed above), all with no success.
How can I display HTML code on a form without having to add a webbrowser control?
View 1 RepliesI have a vb windows application with 2 forms, where form2 is called from form1 using form2.showdialog()
I added a web browser control to form2, and I'm getting the following error at the point where form2 is called:
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
I tried:
1) adding STAThread() to the form_load()
2) I added a module to my application, and created a sub main(), with the STAThread attribute applied to it
3) I marked the sub startup() with STAThread()
I have a WebBrowser control in my VB.NET application that loads a PHP page inside it. On the PHP page I have a 'Log Out' hyperlink. What I'm trying to do is close the VB.NET form when that hyperlink is clicked.
View 1 RepliesI have implemented webbrowser control in my windows application. I have some functions inthe class file. i want to use those functions from the webpage which is displayed in my windows app through webbrowser control..For example say... I have an standalone windows software. Which has a webbrowser control in the some form. Now i would like to create a webpage that can be displayed in the webbrowser control in win app which has some buttons and textboxes. When i click on button in the webpage it should get the version number of that software. I have some other functions that are in the class file aswell.. but dont no how to call those functions from that webpage when a button is clicked or something like that.
View 4 RepliesI have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?
View 3 RepliesI have a VB windows application and I need a way to control input output from this windows application to a batch file.The batch script is quite complex so converting to a VB console application is out of the question because it will too much time.An simplified example is this:I have this batch file test.bat(just for example)
@echo off
set /p choice=name : %choice%
echo Hello %choice%!
In this batch file the user input the name which is then stored in a variable and after the user press enter on the screen will appear Hello + user input.
1. Is it possible to enter the name in a textbox from the windows form and by pushing a send button pass the name to the batch application and then the batch file to continue the operation of displaying the Hello message?
2. After the batch file finishes the operations it will open another console windows (3) with status of the various operations that take place on the system(in my case connected users to a server)Is it possible to hide this child console windows that are generated after my main .bat application finished the operations of opening connections?Can this be done from the windows application or I need to modify the .bat script?
3. Is there a way to collect the console windows output in a textbox from the windows application?One idea that came to me was to redirect the console output to a textfile and then read the textfile in the VB application but I want to know if there is another way.
4. Is it possible to hide this batch file inside the windows application exe?

View 3 RepliesI am currently trying to be able to set the HTML in a WebBrowser control. The bit that I am having the trouble with is that when I go to put the HTML in the WebBrowser control on Form.Load or Form.Activated the WebBrowser1.Document.Body is Nothing. This means when I try to do; WebBrowser1.Document.Body.InnerHtml = value I'm getting an exception as I am trying to use it.I have also tried setting the HTML on the DocumentCompleted event for the WebBrowser control, but that event doesn't fire when I load the form (to be honest I didn't think it would but it was suggested somewhere on the Internet).
View 2 Repliesis there a way in vb.net to make it so that if the html in a web browser control contains a certain word then on startup it will show a dialog box. Basically I want to create an update system in which when the update dialog box web browser control html contains the words "update available" then on start up the dialog box will show prompting the user to update.

I want to load some HTML into a webBrowser control, then operate a particular bit of code when it has finished loading.The code operates fine as long as I pause to wait for it to finish loading. If I just run the code without pausing, it sometimes messes up the display. webBrowser.Document Completed doesn't run after Document.write.I don't want to use webBrowser.DocumentText = "..." because that makes an annoying click sound every time it refreshes. A lot of people are annoyed by this. There are countless threads asking how to turn off the click, and using .write seems to be the only solution that doesn't require hacking the registry.

Ok you know how our web browsers like Internet Explorer or FireFox has the option to "Save Page As". Is there a way to do this using the Web Browser Control? I wish to save the HTML + Images that are displayed in my Web Browser Within my application. Or say if I go to a website and they have a dynamic image that keeps Changing is there a way to save that image that is displayed on the Web Browser control?

WebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

I'm probably missing something really simple or trying too much at once but it's 16:30 on a Friday afternoon and my head is wrecked Basically, I'm trying to build an application that takes out put from a database query as XML and uses XSL to transform it into HTML which is then displayed in a web browser controll on another form.
I thought I break it up into pieces so I decided to just create an XML file and an XSL stylesheet and read this into the web browser control but all I'm getting is <HTML></HTML>

Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
