c# - How to encrypt file name on upload and decrypt on download? -


made asp.net web application receives file using file upload control , encrypts file name on upload.

but when redirect user file_address (so user can download file) don't know how can decrypt file name now? because file (for example .docx file) doesn't have code behind.

so when user downloads file he/she receives file encrypted name!

all files in server have encrypted name , not original name , want know how give files original name when users download files

you can't give user direct link file - rather page first decrypts file, writes appropriate response headers , sends decrypted file response.

like getfile.aspx?encryptedfilename=abcxyz. in init, getfile.aspx loads encrypted file, decrypts it, writes appropriate response headers file, changing mime type whatever file requires, , sending decrypted file instead of web page.

here's example of how zip file. if need more after looking @ this, let me know. how generate , send .zip file user in c# asp.net?

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
