Hi.

Please help

I'm having the same problem.

When i drag a chartspace onto a app form, vs.net generates the codes and recognise the object.

However, when i create the object in web form the vs.net treates it as an object. How did you get Vs.Net to recognise OWC10 in web form?

Cheers

Go to the "bin" folder of your web application

1º)Create a file "owc.bat" with this code:

aximp.exe c:\archivos de programa\archivos comunes\michosoft shared\office web controls\owc10.dll

(or in english pc find the path to this dll.... ;-)

2º) you will have several dll's in your bin folder,

now you can start typing something like this in your code to automate the owc:

Import namespace owc10
(...)
Dim pivottable as New owc10.pivottable

3º) this same aplies to any activex (dll/ocx) you want to use.

4º) hope you post me a good example of using pivottable.... I am working with this now to generate reports sending the pivottable.htmldata property to the client.

good day

That's a good question. Have you tried adding it to the controls collection of your form, or some other container control? There may be an issue here, since it is not a .Net assembly. Give it a try though.

Hi,

Thanks of your helps. But now that I created the object how can I make the reference to the OWC that I created in my webform? or how can I make the just created OWC visible in my webform?

Thnaks again,

Serf

I don't think that OWC provides a .Net component interface. You might be able to set a COM reference in your project. The other option you have is to use late binding (this requires OPTION STRICT to be off).

Dim myChartSpace As Object

myChartSpace = Server.CreateObject("OWC.Chartspace")

Error:Object reference not set to an instance of an object.

Hi there,

I'm a newbee :). What I'm trying to do is to use an Office Web Component in a web App like I did in a Win App. When I drag and drop the ChartSpace object to the web form, window does not generate some code automaticly in the ASPX.vb file; so what I did is copy the similar code like generate automaticly in a Win App (Protected AxChartSpaceData As AxMicrosoft.Office.Interop.OWC.AxChartSpace).
But when a use the object the first time in : AxChartSpaceData.clear() . I got the error.
Does some one know how to use the OWC in a WEb App how to set is object step by step?

I would greatly appreciate any help out there. Thank you.
