If a shell namespace item has the attribute, then it is a shortcut to another location. The most common type of shortcut is the file, which you can load by creating the object and using , but what if you have some other type of shortcut? How do you know what CLSID to use? Since anybody can create their own shortcut file types, a hard-coded li...

A customer reported problems launching the default Web browser with the function: This fails with . If you don't pass the flag and leave , then the function will try to figure out what your refers to, looking at the file extension, looking for the file on the , and if all else fails, trying some autocorrection.

Via the suggestion box, Sys64738 asks, whether I think is a good C/C++ programming style to add IN and OUT to function prototypes. Remember, this is my opinion. Your opinion may validly differ.

Sure, you could do that, but the cost of getting the name is part of the prob...

One of my colleagues tipped me off to some additional resources on the subject of using the DropTarget technique for accepting files for execution. First, it turns out that there is an SDK sample that demonstrates the DropTarget technique after all.
