From: Satchmo on 9 Aug 2010 00:40 Hi all! I'm trying to make my little app "international-aware" and I'm using the GetKeyNameText() function to retrieve the name of a key. The function works good in getting the key names based on the current keyboard layout. The reason I'm doing this is because users of my app will be able to access the settings to customize the program's hotkeys, so I would like to display these in the user's language. For example, the following key name retrieval work: GetKeyText(vbKeyControl ) -> "Ctrl" GetKeyText(vbKeyShift ) -> "Shift" GetKeyText(vbKeyMenu ) -> "Alt" However, the following don't: GetKeyText(vbKeyAdd ) -> "Num +" GetKeyText(vbKeySnapshot) -> "Sys Req" Questions: 1. Why does GetKeyNameText() return "Num +" instead of "+" (the actual label of the key)? 2. Why does GetKeyNameText() return "Sys Req" instead of "Print Scrn" (the actual label of the key)? Below the code I'm using, thanks in advance for any help! -Satchmo -- Private Declare Function GetKeyNameText Lib "user32" Alias "GetKeyNameTextA" (ByVal lParam As Long, ByVal lpBuffer As String, ByVal nSize As Long) As Long Private Declare Function MapVirtualKey Lib "user32" Alias "MapVirtualKeyA" (ByVal wCode As Long, ByVal wMapType As Long) As Long Public Function GetKeyText(KeyCode As VBRUN.KeyCodeConstants) As String Const MAXBUFFERSIZE As Long = 256 Dim buf As String Dim chars As Long Dim ScanCode As Long ScanCode = MapVirtualKey(KeyCode, 0) buf = Space$(MAXBUFFERSIZE) chars = GetKeyNameText((ScanCode * 2^16), buf, MAXBUFFERSIZE - 1) GetKeyText = Left(buf, chars) End Function

How do I capture the "Print Scrn" text of that key? Just curious, I just switched from my English input locale to Swedish (LCID &H041D) using the APIs MapVirtualKeyEx() and LoadKeyboardLayout() and I got the following outputs (verbatim by letter/case): Virtual Key English Swedish -------------------------------- vbKeyControl Ctrl CTRL vbKeyShift Shift SKIFT vbKeyMenu Alt ALT vbKeySnapshot Sys Req Sys Req vbKeyBack Backspace BACKSTEG vbKeyReturn Enter RETUR Just curious, can you confirm these are the labels on your Swedish keyboard's keys?

Caps Lock, Insert, Delete, Home and so on. The only diff is the swedish letters ��� ��� and possibly the shifted AlpaNumeric keys. @ is AltGr+2, $ is AltGr+4, { is AltGr+7, [ is AltGr+8...... > > Just curious, can you confirm these are the labels on your Swedish > keyboard's keys? /Henning
