Access to document object in frame
-There are 2 frames , frame1 and frame2 , in my web page. I want to gain access to the document object of frame1 using vb and web browser. How can I write straight forward codes to do this?
[Code]...
I can access a specific frame and put the frame into a bitmap so that I can process the bitmap.
I am writing code to automate internet explorer. I have successfully done it for a few sites, essentially I need to be able to access the html, and elements such as input boxes to automatically fill out forms, and pull back the results. But for the current project the website has a framset and frames, I was wondering if there is a way to get access to the html and elements within the frame.
I am using Interop.SHDocVw to control internet explorer. I have been trying some code similar to the following, but after I get the frame I need and the documentElement off of it, I can't get the actual html inside the frame. I can get the outer page/framset html, but whenever I try to get inside the frame is comes up as Nothing. I was thinking it may have to do with IE frame security
[Code]...
[code] the part way at the end where it uses .elements(mySearchInput).Value = "bob" I get a compile error it says object variable not set? my guess is this text box is inside a frame called "mainframe" so how would I access an element inside of a web frame? it works fine on another site without frames?
View 1 RepliesI have a VB.Net app that needs to print a bunch of pages from a secure intranet site; the app was made and was working for a non-secure site but now the app needs to login before accessing the web pages necessary to print. I get the error "Object Reference not set to an instance of an object" when I use my new Sub which follows:
Private Sub SiteLogin()
WebBrowser1.Navigate("http://url/login/")
WebBrowser1.Document.GetElementById("user").SetAttribute("value", "username")
[code]....
This Sub prints the given page in IE, so I figured I could use the same WebBrowser1 object for the login Sub, as I don't know how to or whether I should declare a separate object for the SiteLogin Sub. Both of these functions are called after the WebBrowser1 object is defined however. I just need to be able to submit a simple login form to a set URL, and this info needs to all be hardcoded (there's no option to set the location or login info nor should there be).

With vb.net code a Word document is manipulated. In this Word document there is a TextBox object that needs to be moved to a specific position in the document.I tried to start from a recorded macro in the Word document but I can't select the TextBox object while recording.
I tried to find a way using ActiveDocument.StoryRanges(WdStoryType.wdTextFrameStory) but I got stuck here.
Is there a way to move (the left upper corner of) the TextBox object to a specific position in the Word document?

View 1 RepliesMy application needs to extract an embedded file (OLE object) from an excel 2003 document to a file on disk. This file can be any type, not only an Office document. Searching in the web it seems to be possible by copying OLE object to Clipboard and later copying (binary) it to a file (¿perhaps using MemoryStream and FileStream?), but I see no working code about this.

View 2 RepliesI have a solution with several Projects in it. There is a Windows App project (called ImportClient), and a Class Library (Import.Library). The Import.Library has functions to perform data imports (I have other applications in the solution that also need to call it). But the interactive application, I want to be able to pass in some form controls, and have it update the GUI. No problem. But, I also want to execute a DoEvents() so that the loop execution doesn't hang other interaction to the app.
So, ImportClient has a reference to Import.Library. But I can't add a reference to ImportClient to the Import.Library, because the compiler complains about circular reference, etc. I don't know how else to define the My.Application object of ImportClient as a parameter to the data function in ImportLibrary.
(I realize this is a dumb question - problem is, for this project I have a tight timeline, and haven't learned how to do the BackgroundWorker process. If you think I could pick it up quickly, I'm open to some hints about how to update the progress bar on the GUI, and how to pause / cancel the background task.)
If I am using with WebBrowser how I can add tags to source code of the page in runtime (Make a changes on site).
For example: I have site with this

Test page
</head><body>

Now how possible to add elements/tags to text in runtime?

I am getting this error when I call a javascript function to display a modal window:
Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object
The code block is:
else if (action=="officeview") {

ShowFeatureModal('AppView','OfficeContent')
The object is this situation, does exist. Error is caused at: document.getElementById line.What else could be causing the error?
Update:Index.aspx is calling the javascript function which is located in sysUtilities.js file. The source file is yet a seperate page (ChangeView.aspx)
I have a situation where I have an xml document that has a bunch of elements that I basically use as data variables. I populate the variables from various sources and then transform the xml file to an html file for user viewing.having to remember the names of all the data elements in the file is somewhat tedious. Is there a way to generate a strongly typed xml document object so that one can simply dot into the various data elements?

I recently had some problems with the performance of the Word object model. In an add-in that I wrote for Word I need to parse through all the words of a document and replace some of them or ask the user for the ones that have multiple replacements. I know that it is faster to ask Word for all of the document text content at once and then process it and put it back all at once again, but this is not suitable for my add-in because I need to have access to the range objects that represent the words that have multiple replacements so that I can somehow mark them in the document and present the user with a tool tip from which he can select the replacement he wants.
So for the moment the single great speed improvement that came in my head was multithreading since most people already have dual core or better. The problem is that all the things you find on Google say that multithreading in Office is a very bad thing to do.
So is there any one who managed to do this in a manner that worked in most of its usage? By this I mean if it also worked on other PCs then the development one?
how does this function works. How does it copy the frame? HDC BiBlt???
ublic Function copyFrame(ByVal src As PictureBox, ByVal rect As RectangleF) As Bitmap
If isRunning Then
Dim srcPic As Graphics = src.CreateGraphics[code].....
the above function is called from the below command which is in a timer event. mycam is a class including the copy frame function.
bm2 = myCam.copyFrame(PictureBox1, New RectangleF(0, 0, PictureBox1.Width, PictureBox1.Height))
