Decimal Separator. How to keep ‘Input Masks’ and ‘Display Masks’ in Sync with the Settings of the MS-Windows Operating System The country & language settings of MS-Windows include the setting of the Decimal Separator. For most countries this is either a comma or a dot. WinDev will automatically take care of these setting as long as you define all masks in the control’s Description. WinDev will adapt your exe program to the settings of the computer. However, WinDev will not take care of the decimal separator in case you’re building any masks as strings and feed them to the control by using the ..mask property! A mask defined as a string like MyMask is string = “999999.999” and the subsequent feed to an edit control likeMyEdit1..mask = MyMask will inevitably fail if the Windows setting for the decimal separator is a comma !! The only way to get things straight is to read the decimal separator string from the Windows settings and to build the string like MyMask is string = “999999”+DecimalSeparator+”999” So, to make your programs internationally usable, take care of all mask strings in your software! A short procedure (taken from the Wind’Asso web site http://www.windasso.org/cgi-bin/gespage.exe?exec=index&lg=gb ) helps in retrieving the Decimal Separator : PROCEDURE DecimalSeparator()MAX_BUFFER_SIZE is short int=100LOCALE_USER_DEFAULT is long int=1024LOCALE_SMONDECIMALSEP is long int=22 mApiReturn is long intmBuffer is stringmBufferSize is long int mBuffer = RepeatString(Charact(0),MAX_BUFFER_SIZE)mBufferSize = MAX_BUFFER_SIZE - 1 mApiReturn = CallDLL32("kernel32","GetLocaleInfoA",LOCALE_USER_DEFAULT,LOCALE_SMONDECIMALSEP,&mBuffer,mBufferSize)mBuffer = Left(mBuffer,mApiReturn - 1) RESULT mBuffer |
