![]() If StartPosition > HoldLength : ProcedureReturn ucReturnEmpty() : EndIf Store the length of the passed string (in characters). This is the length of the passed string. This is the wide character equivalent of the Mid() procedure. Here's an example of one of the string functions so you can get an idea of how they look.Ĭode: Select all Procedure.l ucMid(inString.l, StartPosition.l, Length.l, EraseOriginal.b) Pass Length = 0 for the rest of the string. Be sure to back up the existing libraries before you copy these over. To use these functions you'll need the W functions from MS so I've included custom *.lib files that should be placed in their appropriate directories (PureLibraries\Windows and PureLibraries\Windows\Libraries). I tried to make them somewhat quick but with only varying results. Two functions to test for a null or empty string, a function to remove delimited string duplicates and a few others. There are also some custom functions like ucCopyString() to completely copy one unicode string into another. There are uncode equivalents of the PB functions - StringField, CountString, FindString, Trim, Mid, Right, Left, RSet, LSet, Len and Str. There are several functions to add strings together (ansi or unicode). There are a lot of supplemental functions to do various things with the string builder as well so check out that part of the code. Should be pretty quick for appending unicode text. For insert strings it has - sbAdd() to add a wide character string, sbAddChar() to add a word value and sbAddAnsi() to add ansi text to our string builder as wide characters. This way you can start the string builder and quickly add strings for whatever task you need. So here's what's included in 'Unicode.pb'.Ī wide character string builder. The main intention is just to have unicode functions available for wide format string manipulation. However, that's not the main intention of the post. The test program is 'Unicode-Test.pb' in the included rar file. Feel free to browse the unicode gadget/window code and see how all of that works. For example, to enumerate the gadgets/windows, I create a custom heap and walk through the heap to locate the required gadget or window. It was actually kind of fun to do and the Window/Gadget code has a few neat tricks in it if you dig through them. If EventTypeW() = #PB_EventType_LeftClickĭoes it look familiar? I know Fred plans unicode support later on but I wanted to learn some things so I fiddled with making a 'Unicode PB' of sorts. If EventID = #PB_Event_CloseWindow : doQuit = #True : EndIf StringGadgetW(#StringTest, 0, 41, 200, 20, HoldString, 0) ![]() TextGadgetW(#TextTest, 0, 21, 200, 20, HoldString, #PB_Text_Border | #PB_Text_Center) Turn on advanced events for our unicode button gadget.īuttonGadgetW(#ButtonClose, 0, 0, 100, 20, HoldString, 0) HandleWindow.l = OpenWindowW(#formMain, 216, 0, 450, 150, #PB_Window_SystemMenu | #PB_Window_SizeGadget | #PB_Window_TitleBar, HoldString, 0) Initialize our unicode functions with out default font. with Ada.Text_Io use Ada.UnicodeInit("Arial Unicode MS", 8, 0) Style uses the #PB_Font_Bold, etc. The last file shows how the Is_Numeric function can be called. package body Numeric_Tests isįunction Is_Numeric (Item : in String) return Boolean is The second file is the package body containing the implementation of the Is_Numeric function. package Numeric_Tests isįunction Is_Numeric (Item : in String) return Boolean The first file is the package interface containing the declaration of the Is_Numeric function. Public function isNumeric(num:String):Boolean If you want to help to improve and eventually enable this page,Ĭreate a boolean function which takes in a string and tells whether it is a numeric string (floating point and negative numbers included) in the syntax the language uses for numeric literals or numbers converted from strings. ![]() Incorrect code, conceptual problems, or other severe issues. This means it might contain formatting issues,
