I'm writing a program to encrypt and decrypt file on the fly, i used filter driver but miss read and write when the application use "mapviewoffile". i don't know how solve this :( , please help me.
First, what does this have to do with Windows Forms? Second, you do realize that NTFS already has the encryption engine built into it, right? As for your problem, it sounds as though you're putting your encryption driver above NTFS instead of below it (close to the disk). You should be encrypting/decrypting disk sectors as written/read instead of trying to encrypt file streams of various types.
