====== PutBinaryValue Function     ======


 
==== Description ====
 
This function will update the contents of a binary variable.
 
==== Syntax ====
 
retval = PutBinaryValue( variable, offset, varType [,varSize])
 
==== Parameters ====
 
The function has the following parameters:

^Parameter^Description^
|variable|A binary structure.|
|offset|A 1-based offset at which to start the insertion.|
|varType|Type of variable you want to insert.  This is the same as it is for [[getvalue|GetValue]], [[lockvariable|LockVariable]].|
|varSize|The size, in bytes, of the data to be inserted.  For CHAR, ACHAR, UCHAR, WCHAR or BINARY varTypes.|
||||

 
==== Remarks ====
 
A buffer must be allocated using the right size or there will be an overflow error.

==== Example ====
 
<code>
/* This example takes the following steps:

 1. Converts an ANSI string to UNICODE

 2. Determines the length of the 2 strings

 3. Creates a buffer for the length of both strings

 4. Places the strings into the buffer

 5. Converts the buffer string to ANSI

*/

 

unicodeString = ""

 

uniCodeString = ANSI_Unicode( "An Example" )

uniCodeLength = GetByteSize( uniCodeString )

moreText = ANSI_Unicode( " of the PutBinaryValue routine" )

moreLength = GetByteSize( moreText )

buffer = str( \00\, uniLength + moreLength )

PutBinaryValue( buffer, 1, CHAR, uniCodeString )

PutBinaryValue( buffer, uniLength + 1, CHAR, moreText)

* Convert the string back to ANSI

newString = Unicode_ANSI( buffer )
