[HtmlEditor] [solved] CLR20r3, FileLoadException, SecurityException, Strong name validation failed.

Atara — Tue, 09 Mar 2010 10:50:29 +0000

I hope the following will help someone -

I tried to compile and run HtmlEditor files [2005 with mshtml.dll].
On my development computer all works fine, but when I xcopy the bin folder to another computer the demo app did not work.
The only error I received was -

DemoHtmlApp.exe has stopped working

Description:
Stopped working

Problem signature:
Problem Event Name: CLR20r3
Problem Signature 01: demohtmlapp.exe
Problem Signature 02: 1.0.3708.26933
Problem Signature 03: 4b8673ca
Problem Signature 04: DemoHtmlApp
Problem Signature 05: 1.0.3708.26933
Problem Signature 06: 4b8673ca
Problem Signature 07: 4
Problem Signature 08: dd
Problem Signature 09: System.IO.FileLoadException
OS Version: 6.0.6000.2.0.0.768.3
Locale ID: 1033

so I added Try-Catch in the Main() [DemoHtmlApp, Form1.cs] -

try {
Application.Run(new Form1());
} catch (Exception e) {
Debug.WriteLine("Main exception: " + e.Message);
MessageBox.Show("Main exception: " + e.ToString() );
throw; // empty Throw for Vista WER [Windows Error Reporting]
}

now I received some more info -
System.IO.FileLoadException: Could not load file or assembly
'Microsoft.mshtml, Version=7.0.3300.0, . . .' or one of its dependencies.
Strong name validation failed. (Exception . . . 0x8013141A)
File name: 'Microsoft.mshtml, ersion=7.0.3300.0, . . .'
. . .
System.Security.SecurityException:
Strong name validation failed. (Exception . . . 0x8013141A)
The Zone of the assembly that failed was:
MyComputer
at onlyconnect.HtmlEditor..ctor()
at . . .

even when verifying that I do use "copy local" for "Microsoft.mshtml.dll"

Googling around, I verified that I do not use "Project Properties | Signing" in both HtmlEditor project and HtmlEditorDemo project.
and also - donot use "Enable ClickOnce Security settings" on the HtmlEditorDemo project - to avoid creating the manifest file with all its permissions handling.
I also learned that I cannot use "Add reference" from just browsing to "Microsoft.mshtml.dll"
so I removed its reference from the HtmlEditorDemo project and re-add it, using the .Net tab.
I had 3 options for the file:
"c:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools for Office\PIA\Office11\Microsoft.mshtml.dll"
"c:\Program Files\Microsoft Visual Studio 9.0\Visual Studio Tools for Office\PIA\Office12\Microsoft.mshtml.dll"
"c:\Program Files\Microsoft.NET\Primary Interop Assemblies\Microsoft.mshtml.dll"
Fortunately, I chose to take the PIA file, it also happens to be "File Version 7.0.3300.1" and not "7.0.3300.0" as the Office files
(Though the inner File Version is also 7.0.3300.0)
[Some sites claims that the Office files are "delay signed" or "partially signed" but the PIA file (installed with the VS installation) is a fully signed copy.]

xcopy the bin folder to the testing computer and now all works well!

Development OS: XP + IE6 + VS 2003 + VS 2008 + Office
Testing OS: Vista + IE8,
(the working solution was also tested on XP + IE6 without VS\Office installed)

If anyone have any hint to the "Access is denied" error when running the demo of the last HtmlEditor version (without the mshtml file) It will help a lot.

yes. I compiled your project using VS2008, and run the demo locally, on my computer. I can "Load HTML", but when I try to run the menu option "Test | Execute Script" I get the exception "Access is denied".

. . . the code in [URL: http://codecentrix.blogspot.com/2008/02/when-ihtmlwindow2document-throws.html] looks almost the same as in comsupport.cs (line 350)

Are there code-experts that understand the above link, compare it to HtmlEditor code, and can explain it ?

I loaded the sln in VS 2008, and when running DemoHtmlApp, I also get the "Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))" error .

Has anyone solved it?

Mayank, I'm not sure if this will fill your needs but you might take a look at

That was extremely helpful, so thanks so much! I adapted it to a simpler case and it worked a treat.

As to Mayank's "DocumentComplete" - I wish I could get it to fire at all. It's causing me lots of grief. Anyway, meanwhile one major problem has been solved.

I got it working (in WPF) by adding [ComVisible(true)] to the HtmlSite class.

[HtmlEditor] ViewLink & IFrame Detach Issue

Blade MF — Thu, 26 Nov 2009 09:31:39 +0000

Hi,

I am developing a bunch (a lot) of binary behaviors with C#. The problem is, that in some occasions IElementBehavior.Detach is not being called.

For example, if you have a simple html page with a single IFRAME in it, then, in the document in the IFRAME you put a binary behavior element, which creates a ViewLink. If you create another binary behavior element in the viewlink document, and the refresh the IFRAME, the Detach method of the inner element is not being called.

HTML Page
|- IFRAME
|--- HTML Page
|----- Element1
|------- ViewLink document
|--------- Element2

I have a very simple code that demonstrates it.

I played arround with it for a few days and found out that if you force a garbage collection in the Element1.Detach, once in a while, Element2.Detach is called.

This means that there is some .NET object holding a reference that it should't hold.

The fun part is that this does not happen when NOT in a IFRAME - everything gets detached in time.

Does anyone have any idea?

[HtmlEditor] About find and replace in HTMlEditor

Prachi — Sat, 21 Nov 2009 12:10:29 +0000

Hello,
In my code I want to internally find a particular word and replace it with other.
I have used Webbrowser control in editable mode.I am using IHTMLTxtRange for finding a word and replacing it with other word.I have to find and replace internally in my code.

Following is my code:-

Public Sub FindReplaceText(ByVal sfindText As String, ByVal sReplacetext As String)
Try

FindReplaceReset()
FindReplaceAll(sfindText, sReplacetext, False, False)
Catch ex As Exception

End Try
End Sub

Private Sub FindReplaceReset()

document = DirectCast(HTMLEditor.Document.DomDocument, IHTMLDocument2)
body = DirectCast(document.body, HTMLBody)

' reset the range being worked with
_findRange = DirectCast(body.createTextRange(), IHTMLTxtRange)
DirectCast(document.selection, IHTMLSelectionObject).empty()

End Sub
' replaces all the occurrences of the given string with the other
Private Function FindReplaceAll(ByVal findText__1 As String, ByVal replaceText As String, ByVal matchWhole As Boolean, ByVal matchCase As Boolean) As Integer
Dim found As Integer = 0
Dim replaceRange As IHTMLTxtRange = Nothing

Do
' find the given text within the find range
replaceRange = FindText(findText__1, matchWhole, matchCase)
' if found perform a replace
If replaceRange IsNot Nothing Then
replaceRange.text = replaceText
found += 1
End If
Loop While replaceRange IsNot Nothing

' return count of items repalced

Return found
End Function
'FindReplaceAll
' function to perform the actual find of the given text
Private Function FindText(ByVal sfindText As String, ByVal matchWhole As Boolean, ByVal matchCase As Boolean) As IHTMLTxtRange
' define the search options
Dim searchOptions As Integer = 0
If matchWhole Then
searchOptions = searchOptions + 2
End If
If matchCase Then
searchOptions = searchOptions + 4
End If

If Not _findRange.text Is Nothing Then

' perform the search operation
If _findRange.findText(sfindText, _findRange.text.Length, searchOptions) Then
' select the found text within the document
_findRange.[select]()
' limit the new find range to be from the newly found text
Dim foundRange As IHTMLTxtRange = DirectCast(document.selection.createRange(), IHTMLTxtRange)
_findRange = DirectCast(body.createTextRange(), IHTMLTxtRange)
_findRange.setEndPoint("StartToEnd", foundRange)
' text found so return this selection
Return foundRange
Else
' reset the find ranges
FindReplaceReset()
' no text found so return null range
Return Nothing

End If
Else
' reset the find ranges
FindReplaceReset()
' no text found so return null range
Return Nothing
End If
End Function

It works fine for all find and replace except if the word contains vbnewline.If in webbrowser control I enter

Hiii

Hello.

The above two words contain Enter key(i.e vbnewline) between them.If I pass following string to my Method it doesn't recognize the whole word and doesn't replace the word. I have called my method as

FindReplaceAll("Hii"+vbcr+"Hello","HiiiHelloReplaced", False, False)

Can anyone tell me why is it so?

[HtmlEditor] Re: Help with anchor tags for MSHTML based editor

danobrega — Mon, 09 Nov 2009 14:54:47 +0000

I can't understand how you managed to use the BeforeNavigate event. This event is fired by IDocHostUIHandler.TranslateUrl. From my testing when we load an email from memory, if a user clicks a link to an anchor in the same document (href="#anchorid" the strURLIn parameter of TranslateUrl will contain "about:blank".

The biggest problem is that in this situation mshtml does not scroll to the anchor location.

Do you know if there is any way to detect that mshtml wants to navigate while having access to the whole URL?

Regards.

Prabhath Pallati — Thu, 25 Jun 2009 15:25:17 +0100

I was also facing the same problem till now but I found a solution to this.

In IHTMLStyleSheetsCollection interface under comsupport.cs contains the following declaration for IHTMLStyleSheetsCollection.item function:

[DispId(dispids.DISPID_IHTMLSTYLESHEETSCOLLECTION_ITEM)]
object item([In] object pvarIndex);

instead there should be the following declaration:

[DispId(dispids.DISPID_IHTMLSTYLESHEETSCOLLECTION_ITEM)]
object item([In] ref object pvarIndex);

which will solve the problem.

[HtmlEditor] Re: Calling the onchange of an IHTMLSelectElement

Corey — Thu, 18 Jun 2009 00:08:34 +0100

I need to know the return value returned by the javascript method called by the event that I'm calling using FireEvent (using the code above).

The IHTMLEventObj is supposed to have this value set in the returnValue property but it is always null (instead of true or false).

Any ideas how to get this working? I'm calling the onclick event of a hyperlink and if the return value is false then the hyperlink should not be clicked, otherwise if it is true then it should (by calling IHTMLAnchorElement's click method).

Any help would be appreciated. Thanks!
