Webservice conversion status.

[iw3arv]

Hello,

I've, probably, a simple problem but I'm not able to figure the
solution!!!

I've realized a web service method that reads an Excel sheet and
convert the information in xml. This conversion is time consuming and
I've the idea to spilt the web service in 3 metods:

"Xls2Xml" that converts the files, generate the xml and store it in the
server, returns the id of the operation
"ConversionStatus" that ceck the progress of "Xls2Xml" sending the id
of the operation.
The client could ceck with "ConversionStatus" the progress of the
operation
Last metod "GetXml" to get the converted file sending the id of the
operation.

The client would fire "Xls2Xml", ceck with "ConversionStatus" if the
operation is completed and download the file with "GetXml".

My first idea was to write on the server a text file that contains the
status of the conversion.
The name of the file is the "GUID" of the operation.
With "ConversionStatus" i could read the text file and know the
progress of the operation.

This is a newbe solution obviusly!!!!
I imagine that there is the possibility to read directly with
ConversionStatus a variable generated by Xls2Xml that contains the
progress of the operation.

How I can do this? It involves threading?

Thanks Paolo Mattiollo

Hi Paolo,

The consumer of your service can just call the GetXml method asynchronously so there might not be a need for any extra work on your
part.

If the web service proxy (client reference to your service) is generated in Visual Studio .NET it will contain two extra methods:
BeginGetXml and EndGetXml. Just add a "Web Reference" to your project and the proxy will be created for you.

Call BeginGetXml to invoke the method asynchronously. When the client has finished its local work it can call EndGetXml, which will
block until the server has finished its work. If the server has already sent a response then EndGetXml will immediately return to
the caller with the result of the method. BeginGetXml returns an IAsyncResult object that must be supplied to the EndGetXml method
to end the request. You can supply an AsyncCallback delegate to the BeginGetXml method which will be invoked on a ThreadPool thread
after the request has completed. If you don't want to use a callback just pass in null. The final parameter of BeginGetXml is an
optional state object that will be supplied to the callback by the IAsyncResult.AsyncState property. Assign whatever data you want
to this parameter, if any.

Hi Dave Thanks for the response.

Unfortunately the proxy used in the client side is made by PHP and
doesn't have that metods.

Hi Paolo,

I'm not familiar with PHP. Does it support asynchronous method calls?

It will save you some trouble if it does, otherwise I think your stuck with your original idea except that the PHP client will have
to periodically call a web service method to check on the status of the asynchronous request. I don't think there is any way, via a
web service, to raise an event or send a notification to the client.
