Checks for the specified substring at the beginning of the specified text.
function TextStartsWith( const S: string; const SubS: string ): Boolean;
Parameters |
Description |
S |
Text to be examined for the specified substring at its' origin. |
SubS |
String to look for at the origin of the specified string. |
Boolean - True when the string begins with the specified substring.
TextStartsWith is a Boolean function used to determine if the text specified in S begins with the value specified in SubS. TextStartsWith is a convenience function that also encapsulates the platform- or OS-specific mechanisms require to perform the text comparision.
For the .Net platform, TextStartsWith calls the Compare method in the System.String class using the indicated string and substring to perform a case-insensitive comparision.
For the Windows operating system, the CompareString function in the Win32 API is called to perform a case-insensitive comparision.
On the Linux platform, the AnsiCompareText method from the Sys class helper is called to perform a case-insensitive comparision.
TextStartsWith returns True when the specified substring occurs at the beginning of the specified string.
Use TextIsSame to perform a case-insensitive comparison for the entire contents of two string values.
