OWC11 - Chart not displaying

I have the exact same problem, same error message, "System.InvalidCastException: QueryInterface for interface OWC11.ChChartSpace failed." Works great on my development machine. Have you solved yet?

 

Sure did! Here's a working sample...

 

Has anyone gotten OWC11 to work in C#? I've tried different combinations of ChartSpace, ChChartSpace and ChartSpaceClass to no avail.

 

Ladies/Gentlemen! Has anybody, but Frank Hewitt, managed to SUCCESSFULLY run -- at a DiscountASP server -- his (or any other) code implementing OWC11? The code in question had been posted on 1/11/2005, and works fine in a local environment (like any other implementation of the same component.) If you have a clue, please share it with me. Also, where can I find detailed specifications of the control properties & methods? Thank you.

Detail: the code fails at the first line, the class instantiation...

chartspace = CreateObject('OWC11.ChartSpace')

Error: ?QueryInterface for interface OWC11.ChChartSpace failed?

 

Thank you, Bruce, for your prompt reply! Unfortunately, it doesn't help since it doesn't have a positive input. (The Interop I uploaded is the one created by VS.NET after I'd referenced the component, and, simultaneously, the one that works fine on my machine.) Please understand: I am NOT saying you?re wrong, not at all. However, I am still facing the same questions:

A. How to proceed from this point on?

B. Where can I find a detailed WRITTEN description of OWC11 class?

Thank you again,

Thank you, Bruce,

Please reveal to me what you found in the referred article special/unknown, which is able to move us forward. Yes, the code of the article works Ok locally (in .NET) but fails in the DiscountASP .NET environment right in the first active line, INSTANTIATION of OWC11 component!!! Since I don't know my server's settings, let alone the access to it, I cannot open a ticket with Microsoft seeking their help. In this case, I believe, it is a full responsibility of the provider to resolve the problem. It's not about helping a client to debug his application. The code is tested, and proved in local .NET environments. I cannot understand why DiscountASP resists opening a ticket with Microsoft.

Thank you,

Thank you, Bruce.

Have you noticed that the instantiation works fine in plain ASP but fails in ASP.NET?

 

Hello,


I have a problem, I don't know how to create a Word document using OWC, people, please help me.


Who knows it, please write a sample code or send it to my e-mail [email protected]


Thank you

 

Why do you need the OWC to create a Word doc? Isn't it like taking a plane to cross a street?

 

Bruce,

Why to deem the situation a conundrum? Opening a ticket with Microsoft doesn?t cost a fortune, just the opposite It will put an end to the problem once and for all. You work for DiscountASP; it cannot be hard, can it??

As a matter of fact, I have worked with them on a number of occasions, both 'officially' (while working for Computer Associates) and as a private developer. I agree, generally, they're not responsive and knowledgeable enough (like people everywhere.) However, if one demonstrates perseverance, and elevates the trouble ticket to a certain level then they give up sooner or later, find the right person, and discover a solution to the problem. Have I convinced you, Bruce?
