SUMMARY
KEYBOARD.DRV in Eastern European versions of Windows version 3.1 has additional virtual keys. The ToAscii function is modified in these versions of Windows to support the dual mode keyboard driver.

MORE INFORMATION
Here's the syntax for ToAxcii:

  ToAscii(UINT uVirtKey, UINT uScanCode, BYTE FAR* lpbKeyState,      DWORD FAR* lpdwTransKey, UINT fuState) In Eastern European versions of Windows version 3.1, uVirtKey has a few additional values specifically intended for these Windows.

  VK_GETSTATUS    0x8A VK_SET_PRI     0x88 VK_SET_SEC     0x89 By using these Eastern European specific virtual keycodes, the application can check the current keyboard status, or set the keyboard mode.

To Check keyboard status, use this code:

  uiStatus = ToAscii(VK_GETSTATUS,....); if(uiStatus == VK_SET_PRI) MessageBox(hWnd, "Primary Mode"...); else if(uiStatus == VK_SET_SEC) MessageBox(hWnd, "Secondary Mode"...); else MessageBox(hWnd, "You use non-EE KEYBOARD.DRV"...); To set Primary mode, use this code:

  ToAscii(VK_SET_PRI,...); To set Secondary mode, use this code:

  ToAscii(VK_SET_SEC,...); Additional query words: 3.10 WM_KEYBOARDCHANGE
