Dear Peter,
What is slow is CreateObject/new ActiveXObject (initialization) call for QP2 objects.
I have never found another COM that is SO SLOW in initialization.
This is not AmiBroker's fault, because I have tried many different objects
including AmiBroker's own OLE objects from AFL (there are used by Dimitris also everyday) and they
run very fast. I tried also FileSystemObject and a number of other COM objects.
None of them were anyway near that slow.
You have not noticed that in your code since you call CreateObject only once
and a second does not make a difference for you. (But since scripting engine is initialized
on stock-by stock basis I can not use this approach yet)
See the following code that performs CreateObject only and demonstrate the slowness
(this time in VBScript):
EnableScript("vbscript");
<%
Set oCompanyInfo = CreateObject("QuotesPlus.CompanyInfo")
%>
buy=sell=cum(1) == lastvalue( cum(1) );
Now compare the performance with the following code that does EXACTLY the
same but creates Microsoft File system object:
EnableScript("vbscript");
<%
Set fso = CreateObject("Scripting.FileSystemObject")
%>
buy=sell= cum(1) == lastvalue( cum(1) );
The second code is hundred times faster. From the AFL/AmiBroker side there is no
difference in handling both cases. The only difference is the object being created.
Errors on your machine: will try to find the reason, but I haven't noticed any
problem on my 2 machines that I use for testing.
Best regards,
Tomasz Janeczko
