Using Bindevent in VFP

I am currently facing an issue with event handling in Thinfinity.VirtualUI and would greatly appreciate any guidance and expertise.

I have integrated Thinfinity.VirtualUI into my application, and I am using the UploadFile method to upload files. Upon completion of the upload, an event named "OnUploadEnd" is supposed to be triggered, providing me with the name of the uploaded file. I would like to capture this event and execute a VFP program or method called "OnUploadEnd_EventHandler" that accepts the file name as a parameter.

To handle this event, I have attempted to use the BINDEVENT function as follows:

VirtualUI = CREATEOBJECT('Thinfinity.VirtualUI')

BINDEVENT(VirtualUI, "OnUploadEnd", loEventHandler, "OnUploadEnd_EventHandler")
VirtualUI.UploadFile(gTempdir)

However, despite the successful upload of the file, the event is not being captured and the "OnUploadEnd_EventHandler" method is not executed. I would greatly appreciate any assistance in identifying the issue and providing guidance on the correct approach to handle the "OnUploadEnd" event in Thinfinity.VirtualUI.

In my pursuit to resolve this issue, I came across the following blog post, which describes a similar scenario and provides some background information on the topic: https://blog.cybelesoft.com/upload-remote-files-web-enabled-applications. This is a fantastic product but the technical help files are sparse.

Thank you in advance for your valuable support. I eagerly await your response.

I have tried using Bidevent in various different ways but have been unsuccessful.

I have been given the following
can try this function:

UploadFileEx(const ServerDirectory: WideString; out FileName: WideString): WordBool;
Once the UploadFile ends it will trigger the following event:
OnUploadEnd(const FileName: WideString)

I do not however know the filename on the PC the user wishes to upload.

To capture Com objects events you should use a eventhandler.

Use the the object browser to create the evenhandler class:

• open Thinfinity com library in the object browser
• locate the interfaces section; if there's more than one interface, locate the one that has the onuploadEnd in the methods section
• drag and drop the interface to an empty prg and you'll get the eventhandler class named as 'myclass'
• write the desired code under onUploadEnd()

then do:

VirtualUI = CREATEOBJECT('Thinfinity.VirtualUI')
vuiEventHandler = CREATEOBJECT('myclass')
eventhandler(virtualUi,vuiEventHandler)

Look for EVENTHANDLER in vfp help.
