WebClientIsReady - property of object PmData

Detects whether the object is ready to write/read to Web server. In this case the PmData object is the Web client.
WebClientIsReady As Boolean
b = oData.WebClientIsReady
true - the object is ready to transfer the Web data (i.e. the ReadFromWeb or WriteToWeb method can be called)
false - the object is not ready to transfer the data (the data from the previous calling the referred methods is still transferring)
Property access for read only.

This method is not functional for PmFree.

The object gets in the transfer of data state by calling the ReadFromWeb or WriteToWeb method. During the transfer these methods cannot be re-called over the object and the WebClientIsReady property then returns the value false. After the transfer (i.e. after the onEndOfTransfer event fires) the methods can be called again and the WebClientIsReady method returns the value true.
