问题
Its basically the same as in windows, but when your trying to set file associations to a program that lives inside a folder that has spaces in it you need to get the "short" name of that folder. In regular windows i use this:
[System.Runtime.InteropServices.DllImport("Kernel32.dll")] private static extern uint GetShortPathName(string lpszLongPath, [Out] StringBuilder lpszShortPath, uint cchBuffer);
So my question becomes, does anyone know of a built in function i can use to replace the above function, or know of a exacly what this function does so i could recreate it in C#.
回答1:
Windows CE, which is the base of WinMo, doesn't use 8.3 file naming for anything, so I'm certain that you don't need to use them for defining file associations.

Who said you need the short path to set the file association in regular Windows? I just tried it myself real quick, and had no problems adding the keys to the registry with spaces. I then double checked the registry and sure enough, there are spaces there. The file type I associated with the program launches just fine, and the program lives in a directory with multiple spaces all over the place.
