It would be so incredibly awesome if Dominic Mitchell would convert over to FreeBasic as well. Dominic and Jose are the two smartest PB programmers on the planet.

I may be wrong but I get the impression Dominic is more commercially motivated than is Jose.

Since we can use the Free Basic intrinsic array procedures to work with arrays of CWSTR strings, I have added some helper functions to CWSTR.inc.

I wonder if there is a way to detect if an array is fixed other that checking if REDIM PRESERVE has failed.

hi，jose

    Happy Christmas, thank you for your hard work, bringing Freebasic an easy-to-use framework.

[José Roca]

Thank you for using it. I wish you a Happy New Year.

[José Roca]

Removed "Pass -1 to use the default styles." in the documentation of the dwStyle and dwExStyle parameters of the Create method of the CWindow class. This was a leftover of an earlier version.

AfxResizeTabPages function
Changed FUNCTION AfxDestroyAllTabPages (BYVAL hTab AS HWND) AS BOOLEAN to FUNCTION AfxResizeTabPages (BYVAL hTab AS HWND) AS BOOLEAN.

ComboBox_ResetContent
Changed "Limits the length of the text the user may type into the edit control of a combo box." to "Removes all items from the list box and edit control of a combo box."

TOOLINFOW
Changed "Contains information specific to an NM_CUSTOMDRAW notification message sent by a ToolTip control." to "Contains information about a tool in a tooltip control."

AfxSetPrinterCollateStatus
Changed "Switches between color and monochrome on color printers." to "Specifies whether collation should be used when printing multiple copies."

CFileSys
Several methods were documented as returning a CWSTR instead of a CBSTR.

AfxGdiPlus.inc

FUNCTION GDIP_RECT ( _
   BYVAL x AS LONG, _
   BYVAL y AS LONG, _
   BYVAL nWidth AS LONG, _
   BYVAL nHeight AS LONG _
) AS GpRect

Returns a GpRect structure initialized with the specified values for the x, y, width, and height components.

FUNCTION GDIP_RECTF ( _
   BYVAL x AS SINGLE, _
   BYVAL y AS SINGLE, _
   BYVAL nWidth AS SINGLE, _
   BYVAL nHeight AS SINGLE _
) AS GpRectF

Returns a GpRectF structrure initialized with the specified values for the x, y, width, and height components.

[Vinod Chandran]

Hi,
I am learning some new stuff from WinFBX framework. Such a giant library and it gives more simplicity to FreeBasic. Especially i love Cwstr library. It is must have for any language. Dynamic unicode string handling is a must have feature. By the way, i got stumbled upon the usage of period in some functions. For example, in DoEvents function.

Code: [Select]

' // Show the window and update its client area
   IF nCmdShow = 0 THEN .ShowWindow m_hwnd, SW_SHOW ELSE .ShowWindow m_hwnd, nCmdShow
   .UpdateWindow m_hwndSee this line ? What is the meaning of that period in the left side of ShowWindow function.  I know that ShowWindow is an api function. Then why it is used with a period ?

[José Roca]

To avoid possible name conflicts, present or future. It makes sure that it calls that symbol in the global namespace and not a duplicate symbol in another namespace.

If someone else writes a class with a method called ShowWindow, and you use it together with mine, without an "." my code won't know if you intend to call the API function ShowWindow or the ShowWindow method of the other class.

All the code that I have written with FreeBasic is unicode aware. It is unavoidable if one wants to attract international users. And with the WinFBE editor you can use unicode string literals if you save the file with the option UTF-8 BOM. The string literals will be saved in the file as UTF-8, but the CWSTR class will perform the conversion. This way you can work as if dynamic unicode strings were natively supported by FreeBasic.

DIM cws AS CWSTR = "Дмитрий Дмитриевич Шостакович"

WYSIWYG (What you see is what you get), without having to use CHR.

[Vinod Chandran]

Yeah, Thanks for the reply. Is there any dynamic list or array feature in WinFBX  framework ? Does CSafeArray is a dynamic array ?

[José Roca]

CSafeArray implements support for safe arrays that are used in COM programming. It works with VARIANTs.

We can use CWSTR as if it was a native data type. Therefore, you can have arrays of CWSTRrings as easily as arrays of FreeBasic ansi strings.

We can use arrays of CWSTR strings transparently, e.g.

Code: [Select]

DIM rg(1 TO 10) AS CWSTR

FOR i AS LONG = 1 TO 10
  rg(i) = "string " & i
NEXT

FOR i AS LONG = 1 TO 10
  print rg(i)
NEXT

A two-dimensional array

Code: [Select]

DIM rg2 (1 TO 2, 1 TO 2) AS CWSTR
rg2(1, 1) = "string 1 1"
rg2(1, 2) = "string 1 2"
rg2(2, 1) = "string 2 1"
rg2(2, 2) = "string 2 2"
print rg2(2, 1)

REDIM PRESERVE / ERASE

Code: [Select]

REDIM rg(0) AS CWSTR
rg(0) = "string 0"
REDIM PRESERVE rg(0 TO 2) AS CWSTR
rg(1) = "string 1"
rg(2) = "string 2"
print rg(0)
print rg(1)
print rg(2)
ERASE rg

And we can also sort one-dimensional arrays calling the AfxCWstrSort procedure:

Code: [Select]

DIM rg(1 TO 10) AS CWSTR

FOR i AS LONG = 1 TO 10
  rg(i) = "string " & i
NEXT

FOR i AS LONG = 1 TO 10
 print rg(i)
NEXT

print "---- after sorting ----"

AfxCWstrSort @rg(1), 10

FOR i AS LONG = 1 TO 10
  print rg(i)
NEXT


[José Roca]

As noted in the documentation, CWSTR behaves as if it was a native data type, working directly with the intrinsic Free Basic string functions and operators. The only exception is MID when used as a statement: Something like MID(cws, 2, 1) = "x" compiles but does not change the contents of the dynamic unicode string. MID(cws.wstr, 2, 1) = "x" or MID(**cws, 2, 1) = "x" works.

It even works with files, e.g.

Code: [Select]

#include once "Afx/CWStr.inc"

DIM cws AS CWSTR = "Дмитрий Дмитриевич Шостакович"

DIM f AS LONG = FREEFILE
OPEN "test.txt" FOR OUTPUT ENCODING "utf16" AS #f
PRINT #f, cws
CLOSE #f

There are also wrapper procedures to Append, Insert and Remove elements of the array: AfxCWstrArrayAppend, AfxCWstrArrayInsert, AfxCWstrArrayRemove, AfxCWstrArrayRemoveFirst and AfxCWstrArrayRemoveLast.

[José Roca]

New help file uploaded. Corrected some inaccuracies in the documentation.

[Johan Klassen]

thank Jose Roca 

[Eros Olmi]

Dear Jose,

I tried to download you .rar files but they seems corrupted.
I use 7-Zip to open them, tied to clear the browser cache, tried to download from different browser but always the same problem.
7-Zip report that "There are some data after the end of the payload data"

I'm the only one having problems?

Thanks a lot
Eros
