Callbacs in ASP

[CNemo]

Hi All!

I would like to be able to make callback function in ASP VBScript.
Last time when i saw it was impossible...

Is something changed in this area now? Maybe workarounds?

Could you get more specific? What are you trying to do?

 

[CNemo]

I would like to have template function to output table, which will accept
other function as a parameter to renrer row.
Sounds to cool for VB?

It sounds do-able with a SSI. Why is a "callback" function needed, and what
do you mean by "callback"?

I would pass an object that provides the needed function. You have also
Eval/Execute. I'm not sure but if I remember you don't have even in
VBScript... do You ?

 

[CNemo]

You mean create class and pass it's instance and then call it's method
inside?
That might be neat.
Thanks a lot! I'll try it.

But if you did it already, i'll will really appreciate small sample!

Something like :

Class ProviderA
Sub DoSomething
Response.Write "ProviderA.DoSomething"
End Sub
End Class

Sub Render(Provider)
Provider.DoSomething
End Sub

Render New ProviderA


Later you can create another class such as ProviderB and pass an object.
Basically you are on your won to ensure that both object expose the same set
or methods/properties...

Thanks!
Nice use for strategy pattern!

Something like :

Class ProviderA
Sub DoSomething
Response.Write "ProviderA.DoSomething"
End Sub
End Class

Sub Render(Provider)
Provider.DoSomething
End Sub

Render New ProviderA


Later you can create another class such as ProviderB and pass an object.
