Problem with .NET 2.0 and MSHTML

[Hans Merkl]

Hi,

I have written an pap with .NET 2.0 and c# that uses MSHTML. It works fine
on my development machine but on machines I deploy it to I get the
following exception when ever I call MSHTML.

"Could not load file or assembly 'Microsoft.msht ml, Version=7.0.330 0.0,
Culture=neutral , PublicKeyToken= b03f5f7f11d50a3 a' or one of its
dependencies. The system cannot find the file specified."

The machine has .NET 2 installed and all the latest patches.

It seems I am using a newer MSHTML version on my development machine. I
wouldn't mind using an older version but I don't know where to get a
typelib for older MSHTML versions.

Has anybody else seen this problem and knows a workaround other than not
using MSHTML?

Thanks

Hans Merkl

Re: Problem with .NET 2.0 and MSHTML

Hans,

If you are using MSHTML, then you might want to consider using the
classes in the System.Windows. Forms namespace which are HTML DOM elements
(HtmlDocument, HtmlElement, and a host of other classes). They should give
you what you need, as well as eliminate that issue with conflicting MSHTML
versions.

Hope this helps.

Re: Problem with .NET 2.0 and MSHTML

That's what I ended up doing. But these classes are quite limited.

For example: Do you know how to create a HtmlDocument object from a file
without using a WebBrowser control? I haven't figured that out.

MSHTML is much more powerful and I know it already.

Re: Problem with .NET 2.0 and MSHTML

Max,

You are right, it is a little limited. In order to do that, you would
have to get the object from the DomDocument property, and cast that to the
IPersistFile interface (you can use the one in the
System.Runtime. InteropServices .ComTypes namespace). Then, you can call the
Load method on the interface, and it should load the contents from disk.

Hope this helps.

Re: Problem with .NET 2.0 and MSHTML

That will cause me to use MSHTML and I will run into my problem again :-)

There must be a solution for this. By default VS.NET references an MSHTML
interop from the GAC. I just need to reference another interop assembly.

'Microsoft.msht ml, Version=7.0.330 0.0,......
is a v1.x assembly, I could be wrong, but I don't think it's part of the
v2.0 Framework. Are you sure it's present in the GAC?

When I look at the properties of the reference in my project I this is the
file location:
C:\WINDOWS\asse mbly\GAC\Micros oft.mshtml\7.0. 3300.0__b03f5f7 f11d50a3a\Micro soft.mshtml.dll

I had the beta versions of the framework installed (uninsitalled them
before I installed the final version though). Maybe that's the problem?

Re: Problem with .NET 2.0 and MSHTML

What I mean is that it should be present in the GAC on the target machine.
If not, you should deploy it with your application, or your should install
the redistributable of the primary interop assemblies (see Program
files\Common Files\Merge modules).

Willy.

Re: Problem with .NET 2.0 and MSHTML

Max,

I don't see how it would. The classes in the System.Windows. Forms
namespace use MSHTML as well under the covers, so it's a matter of your
interop assembly being incorrect.

Re: Problem with .NET 2.0 and MSHTML

You are right. I installed vs_piaredist.ex e from the directory "Merge
Modules" and now it works. I guess the name indicates I can redistribute it
wth my app.

I am getting too old for this.....

Please see my response to Willy. Running vs_piaredist.ex e solved the
problem.
