VB Forum / Win API / March 2008ASCII code from RawInput
I use RawInput to get the key pressed on one of several keyboards attached to the machine. It provides a RawInput Code that indicates which key was pressed but this is not the ASCII code for the key (RawInput codes for the aphameric keys do seem to be the uppercase ASCII code - but those for "special characters" are not.) I can manage the shift, alt and ctl keys OK, but the ASCII meaning of a key is dependent on the keyboard in use. For example, if I shift-press the 4th key on the top row of my English keyboard I get the UK currency symbol £. If you press the same key on a US keyboard, it generates the same RawInput code (xD3) but it means # (or possibly cent - I forget which) Somewhere in Windows there is a table that converts RawInput codes to ASCII depending on the keyboard in use - can anyone tell me where and how to use it from VB.net? > can anyone tell me where and how to use it > from VB.net? not here  SignatureYou need to ask in a newsgroup with "dotnet" in the name. This group is for VB 6.0 and earlier and does not include VB.Net or VB 200x. Since this isn't a .net newsgroup -- those all have "dotnet" or "vsnet" in their names -- it isn't the right place to ask your question. For best results post in an appropriate group. -- Jim Mack MicroDexterity Inc www.microdexterity.com > I use RawInput to get the key pressed on one of several keyboards > attached to the machine.

Often beside the scan code the virtual key code is provided. To map scan codes to virtual key codes, etc. and vice-versa use MapVirtualKey()/MapVirtualKey(Ex). > can anyone tell me where and how to use it from VB.net? See the other answers in this thread!
