Compatibility of Aspose.Words for .NET API with Aspose.Words.ComHelper

Aspose.Words Product Family
1

Is there a new release for Aspose.Words.ComHelper? Your latest release of Aspose.Words is not compatible with the ComHelper class.
My code blowup while trying to create the ComHelper object:

set comHelper = Server.CreateObject("Aspose.Words.ComHelper")

The complete function is as follows:

Sub CreateAsposeObj
'// CREATE THE ASPOSE.WORDS COMHELPER ASP WRAPPER OBJECT TO EDIT WORD DOCUMENTS
set comHelper = Server.CreateObject("Aspose.Words.ComHelper")
licenseFile = rw_cfg("basedir") & "lib\Aspose.Words.lic"
Set License = Server.CreateObject("Aspose.Words.License")
License.SetLicense(licenseFile)
If Err.number <> 0 Then
Response.redirect("/Error.asp?Message=ASPOSE OBJECT COULD NOT BE CREATED - " & err.description )
Response.end
End If
strMergeDoc = strPdfDocSetTmpPath & "MergeDocument.doc"
'set fsObj = CreateObject("Scripting.FileSystemObject")
End Sub

Hi
Thanks for your inquiry. What do you mean? ComHelper works fine on my side. Actually ComHelper is a very simple class it is used only for opening document (you need this class because COM doesn’t support constructors with parameters). ComHelper class looks like the following.

public class DocLoader
{
    public DocLoader()
    { }
    public Aspose.Words.Document LoadFromFile(string path)
    {
        return new Aspose.Words.Document(path);
    }
}

Maybe you should register Aspose.Words.dll in GAC.
gacutil /i C:\Program Files\Aspose\Aspose.Words\Bin\net2.0\Aspose.Words.dll.
Could you please provide me more information about error you get?
Best regards.

The error is as follows:

Server object error ‘ASP 0177 : 80131040’
Server.CreateObject Failed
/Includes/DocFunctions.asp, line 7
80131040

This is the first I’ve heard of “gacutil”. I was told to use “regasm” to register the dll(s). Am I not right?
I successfully ran the “gacutil” command:

gacutil /i "C:\Program Files\Aspose\Aspose.Words\Bin\net2.0\Aspose.Words.dll"

However, it made no difference. I still recieve the same error.
If I use “regasm” to register the an older version of the Aspose.Words.dll everything works fine.
I’ve attached a zipped copy of DocFunctions.asp

Hi
I tried using the following simple code and all works fine on my side.

'Create a ComeHelper
Dim helper
Set helper = CreateObject("Aspose.Words.ComHelper")
'Open document
Dim doc
Set doc = helper.Open(Server.MapPath("in.doc"))
'Create DocumentBuilder
Dim builder
Set builder = CreateObject("Aspose.Words.DocumentBuilder")
builder.Document = doc
'Edit document
builder.Writeln("Edited by Aspose.Words")
'Save document
doc.Save(Server.MapPath("out.doc"))

Have you tried to restart IIS? Maybe this helps.
Best regards.

Yes, I run IISRESET every time I change DLL(s).
I’ve tried running a test program that uses the same ComHelper and I get a little bit different error:

msxml3.dll error ‘80131040’
The system cannot locate the object specified.
/XTest/UploadDoc.asp, line 48

Have any ideas?

Maybe you should also add this dll to GAC. I found the following page, it seems that there is the same problem.

https://dotnet.microsoft.com/en-us/download/dotnet-framework

Best regards.

My attempt to add C:\Windows\system32\msxml3.dll to the GAC failed. See below:
“Failure adding assembly to the cache: The module was expected to contain an assembly manifest.”
Any other ideas?

Hi
Maybe you should use regsvr32 msxml3.dll. Hope this helps.
Best regards.

Already tried regsvr32.
I assume you are using the latest Aspose.Pdf and Aspose.Words, but can you tell what version of AsposeComWrapper.dll you are using? Mine is dated 07/17/2007 12:11 PM and is 16,384 bytes in size.

OK. I must have installed something incorrectly. I uninstalled both Aspose.Pdf and Aspose.Words, downloaded the latest versions of both, and reinstalled them. Things are looking much better now. Perhaps I didn’t select to install for All users the last time.
Thanks for your help.

Hi

It is nice that you found the problem. I created ComWrapper myself using the following manual.

How to create a wrapper to assist in calling Aspose.Words methods from classic ASP

Best regards.

Your link to the “How to create a wrapper to assist in calling Aspose.Words methods from classic ASP” webpage contains the following two links that both default to the “Products” webpage.

  • Utilize Aspose.Words from COM Clients (ASP, VB, VBScript)
  • ASP/ASP.NET without Visual Studio - an Instant Primer

I was expecting more information about the COM helper. Do those webpages still exist?

Default “Products” webpage = File Format APIs for .NET Core, Java, C++, Android

Hi

Please see the following links.

Hi ,
Which version of Aspose.Words is best suitable for this “Aspose.Words.ComHelper”?
Actually, we would like to use Apose.Words for our Classic ASP (VBScript code behind) web portal application.

when try to do POC firstly, we failed to call the dll using Server.CreateObject(“Aspose.Words.ComHelper”) method.
The error message is throw as follows: 006~ASP 0177~Server.CreateObject Failed~800401f3

We tried to register the dll using Gacutil (C:\Program Files (x86)\Aspose\Aspose.Words for .NET\bin\netstandard2.0\Aspose.Words.dll) and it register success.
But still cannot create the object.
Currently we have installed Aspose.Words_22.12.

could anyone help to advise us in this regard? Thanks in advance.

If this product works, then we can proceed further to place the purchase order for the same.

@sravan.kolloju Please try using Aspose.Words dll for .NET 3.5. netstandard2.0 dll is for .NET Core 2.0 or higher.
