I managed encrypting an xml document by encrypting an element and then replacing the element with the encrypted data. A shown in the sample code below. Public Shared Sub Encrypt(ByVal textReader As TextReader, ByVal textWriter As TextWriter, ByVal certificateName As String)

I want to make an application that takes values & innerhtml from some elements on a webpage i made. For that i added a webbrowser to the project, and pointed it to navigate to my localhost server where i have some pages. However when i use the document.getelementbyid i don't get nothing on my richtextbox, and i don't know why, i use this function lot in javascript & i think its quite similar, so i don't know why it doesn't work , here is the code i use.

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?

Class Combination
Combination contains Element 1 and Element 2 and List(Of Element) for the results My Question: Using Game.Elements how can I add a readonly property for combinations of that element.

View 2 RepliesI am automating Word from VB.Net.I open a document by:
Dim msWord as Word.Application = CreateObject("Word.Application")
Dim doc As Word.Document = msWord.Documents.Add(Template:=Path)
where path points to a template file I created with a header and a watermark. The template has some bookmarks which I want to dynamically set to some appropriate text values:
doc.Bookmarks("DocumentTitle").Range.Text = "The Joy of Office Automation"
If I comment out that line, the document opens in Word with the watermark, etc, in place. If I let that line execute, it inserts the text as appropriate, but the watermark and other things disappear from the document. You can actually see it flash briefly, and then disappear.FWIW, this is Office Word 2007, and I am opening a .Dot (Word 97-2003) template. The Bookmark.Range.Text I am setting is in the document header.
I have the following tables
Public Class Tag

Now i have a list of Tags which contain the right TagReferences, but the tags may not be deleted, it's the TagReferences.
Variabels = ReferenceValue,ReferenceID
IEnumerable(Of Tag) = TagRepository.GetMany(Function(el) el.Reference = ReferenceValue And el.TagReferences.Any(Function(bl) bl.ReferencedID.Equals(ReferenceID)))
How can i remove all the TagReferences which contain the ReferenceID in one line?

I want to create a document with several pages and with one wpf window depicted on each page. I managed to print one window using PrintDialog and PrintVisual. However this seem to only work with one single page? How I can build a document with several pages and print the complete set. Can I insert that visual (referred in code) and insert it as a page in a document and print it after that?
Sub Print (Dim ele As FrameWorkElement)
Dim margin As Double = 30
Dim titlePadding As Double = 10
Dim printDlg As PrintDialog = New PrintDialog()

I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

I know how to add a single node to a top level node in an XML document, but I cant figure out how to add multiple (nested) nodes to another node. For example, I want to add this node structure to node called "PaymentInformation":
<Prepaid>
<BillShipper>
<AccountNumber></AccountNumber>
</BillShipper>
</Prepaid>
Do I have to add each node separately or can I add them all at once?

I recently found the benifits of using the WIA APIs for scanning a page from a scanner. However, I am unable to get the scanned images from an ADF. I am using a Brother MFC Multi function printer that has an ADF on top. When I call the Transer() function, the printer scans all the pages...and then the program saves the returned image to a file, but when I open the image file up....only the last scanned page is there. How to scan multiple pages, and receive all the scanned images, from an ADF?
View 7 RepliesI 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?
I am using this:
Dim oFile As System.IO.File
Dim oWrite As System.IO.StreamWriter
oWrite = oFile.CreateText("e: est.txt")
oWrite.WriteLine("TEST")
oWrite.Close()
Which works, but I would like to have it so instead of creating test.txt it names the document using multiple input text instance.
On a word document I would like to populate same data captured via User Form on multiple locations of a document... i.e. LastName I would like to appear on salutation paragraph and also in the body of the letter... I used REF LastName on the document when using VBA but it seems the same document when it is being populated via a VB application this skim does not work and instead "Error! Reference source not found." appears where ever the REF LastName has been used..

I have a requirement where I have to pass some values into the next page via querystring.This querystring is coming from third party and they need to have it on the otherpage for some analysis. I just do a response.redirect and add the querystring that i recieve from them to the other page. My problem is that the .net environment is encoding/encrypting some of the special characters used by them which I dont want as it does not bring back the correct values in the new page.

View 13 RepliesI am actually really new to VB and C#. From numerous tutorials that i found online i was able to create a small program that will encrypt a file. However I am having a really hard time decrying it back.[code]All I am trying to do is to create a program that will decrypte these file with an upload button. Our system encrypts the files to prevent operators from changing the results, we need to trend the data. However it will take way to long to use the online tool provided with the software. A desktop tool will save us much more time. The files generated are 70mb and up.
