Next version will include a localized Input Box dialog. Localization of the buttons is achieved by extracting the strings from the resource file of user32.dll (works also with 64 bit).
Usage example:
DIM cws AS CWSTR = AfxInputBox(hwnd, 0, 0, "InputBox test", "What's your name?", "My name is José")
' ########################################################################################
' *** INPUT BOX DIALOG ***
' ########################################################################################
' ========================================================================================
' Input box dialog
' Parameters:
' - hParent = Handle of the parent window
' - x, y = The location on the screen to display the dialog. If both are 0, the dialog
' is centered on the screen.
' - cwsCaption = Caption of the window
' - cwsPrompt = Prompt string
' - cwsText = Text to edit
' - nLen = [opt] Maximum length of the string to edit (default = 260 characters)
' - bPassword = [opt] TRUE or FALSE. Default FALSE. Displays all characters as an
' asterisk (*) as they are typed into the edit control.
' Note: The maximum length is 2048 characters.
