A good way to show you where I'm headed is with a screenshot. The image inFigure 1shows that I am testing a simple but representative WPF application. The application is called CryptoCalc, and it computes a cryptographic hash of an input string using one of three hashing techniques: MD5...
Click the drop-down menu next to the ThumbNailPhoto node and select Image. 备注 By default, items in the Data Sources window that represent pictures have their default control set to None. This is because pictures are stored as byte arrays in databases, and byte arrays can contain anything fr...
