CharToBin

CharToBin(lcBinString,llSigned)

Parameters

lcBinString
The binary string that contains the 32 bit binary data. This value is usually a value retrieved from a C structure or other memory based buffer.

llSigned
If the value is a signed number rather than an unsigned value set this flag. Note that VFP numeric integers are limited to signed sizes so a large unsigned number that exceeds 2 gigabytes may not translate correctly into a VFP number.

Remarks

This is a free standing function not a method.

This method works only with binary integer values that are exactly 4 bytes long (ie. a DWORD or LONG value).

Example

FUNCTION GetTimeZone

• ** Function: Returns the TimeZone offset from GMT including
• ** daylight savings. Result is returned in minutes.

DECLARE integer GetTimeZoneInformation IN Win32API ; STRING @ TimeZoneStruct

lcTZ = SPACE(256)

lnDayLightSavings = GetTimeZoneInformation(@lcTZ)

• ** First 4 bytes contain the timezone offset

• ** Value is a signed 32 bit Integer lnOffset = CharToBin(SUBSTR(lcTZ,1,4),.T.)

• ** Subtract an hour if daylight savings is active IF lnDaylightSavings = 2 lnOffset = lnOffset - 60 ENDIF

RETURN lnOffSet
