I am trying to use Aspose.Words .NET in Delphi XE via COM, as suggested from the offcial doc. However, the “Arithmetic operation resulted in an overflow” occurs. Could you help to comment ?
https://docs.aspose.com/words/net/supported-platforms/#com
PS:
The .net 2.0 version DLL downloaded from the official repo is used.
https://releases.aspose.com/words/net
PS:
VBScript works…
Dim Doc
Set Doc = CreateObject("Aspose.Words.Document")
Dim Builder
Set Builder = CreateObject("Aspose.Words.DocumentBuilder")
Builder.Document = Doc
Builder.Write "Hi there"
Doc.Save("test.doc")
PS:
The not-working Delphi version …
program Project29;
{$APPTYPE CONSOLE}
uses Aspose_Words_TLB in 'D:\My Documents\RAD Studio\8.0\Imports\Aspose_Words_TLB.pas';
var doc: _Document;
builder: _DocumentBuilder;
begin
doc: = CoDocument.Create;
builder: = CoDocumentBuilder.Create;
builder.Document: = doc;
builder.Write('hi there');
doc.Save('test.doc');
end
Hi Jiaguo,
We are working on this issue and will get back to you soon.
Best Regards,
Thank you for your efforts !
I have done some more test cases , and the trend is attached for your convenience. The .ctp file is also attached. The source code is at the end of this email.
Best wishes,
“Case 1” is to write a paragraph.
//// C#
using System.IO;
using Aspose.Words;
public class Program
{
public static void Main()
{
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.Write("hello world");
doc.Save("test.doc");
}
}
//// VBScript / COM, note: need to call RegAsm.exe to make Aspose.Words.dll accessible via COM
Dim Doc
Set Doc = CreateObject("Aspose.Words.Document")
Dim Builder
Set Builder = CreateObject("Aspose.Words.DocumentBuilder")
Builder.Document = Doc
Builder.Write "Hi there"
Doc.Save("test.doc")
//// Delphi / CrossTalk
program Project29;
{$APPTYPE CONSOLE}
uses CTAspose_Words;
var
AWDoc: Document; // Aspose Words Document AWDocBuilder: DocumentBuilder; // Aspose Words DocumentBuilder
begin
AWDoc: = Document.Create;
AWDocBuilder: = DocumentBuilder.Create(AWDoc);
AWDocBuilder.Write('hi there');
AWDoc.Save('test.doc');
end.
“Case 2” is to insert a image.
//// C#
using System.IO;
using System.Drawing;
using Aspose.Words;
public class Program
{
public static void Main()
{
Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
builder.InsertImage("test.bmp");
doc.Save("test.doc");
}
}
//// VBScript / COM
Dim Doc
Set Doc = CreateObject("Aspose.Words.Document")
Dim Builder
Set Builder = CreateObject("Aspose.Words.DocumentBuilder")
Builder.Document = Doc
Builder.InsertImage "test.bmp"
Doc.Save("test.doc")
//// Delphi / CrossTalk
program Project29;
{$APPTYPE CONSOLE}
uses CTAspose_Words;
var
AWDoc: Document; // Aspose Words Document AWDocBuilder: DocumentBuilder; // Aspose Words DocumentBuilder
begin
AWDoc: = Document.Create;
AWDocBuilder: = DocumentBuilder.Create(AWDoc);
AWDocBuilder.InsertImage('test.bmp')
AWDoc.Save('test.doc');
end.
I have sent the same inquiry to CrossTalk support and the comments are posted below for your convenience

I only got as far as Case1. I can confirm the problem but I have traced
it all the way through into CrossTalk libraries and the exception is not
coming from CrossTalk. The exception is being raised by the Aspose
library when CrossTalk calls the Save method.
Since I do not have the Aspose source I cannot dig deeper. I could use
reflector but that won’t let me trace into the source so locating the
issue will not be easy. I did take a quick look in reflector but their
library is obfuscated so a lot of it is gibberish.
I suspect they are doing something weird like looking for the host
application and trying to get information from it and getting confused
when it doesn’t find something it expects (ie a Delphi exe, instead of a
.NET one).
Aspose will need to run a test case using CrossTalk and a Delphi exe to
resolve the issue or will have to provide us with source to debug.
