TClientDataSet / MIDAS.DLL stopped to work

Question

I use TCLientDataSet often to store local data, using the SaveToFile and LoadFromFile methods.

Everything always worked fine, but somehow now it has stopped to work. When i call SaveToFile method, no exception is generated, BUT nothing is saved as well.

This problem started after i did some tests deleting the 'MIDAS.DLL' file from my app path, but even after i returned it to the path, the problem persists.

Any hints ?

Answer 1

I don't know what happened or why, but after i selected my clientdataset on design time and click again on 'Create dataset' the problem got solved.
