The online help indicates usage of DT_WORDBREAK (enumerates to 16).

I have tried calling this but I do not get any returned word breaks in the text.



Is this function supposed to return the modified text with CRLF, or is there some other trick.

Code is below:





	DECLARE FUNCTION UTILITY

	equ DT_WORDBREAK$ to 16

	

	FONT=GET_PROPERTY("ICEPAC_MENU.BQ_TABLE","FONT")

	WRAP_WIDTH=20

	

	TEXTINFO="

	TEXTINFO=Cost of completing duties of Project Supervisor (Construction Stage) in accordance with the Safety, Health & Welfare at Work (Construction) Regulations, 2001 and Clause 3.1.14 of this Specification."

	TEXTINFO=DT_WORDBREAK$

	TEXTINFO=WRAP_WIDTH

	TEXTINFO=FONT

	

	RESULT=Utility("TEXTRECT","",TEXTINFO)

	SWAP CHAR(13):CHAR(10) WITH @VM IN TEXTINFO

DEBUG

return 1

<QUOTE>Colin,



TEXTRECT only returns the size of the rectangle needed to draw the text - it does not alter the text in any way.  It is basically a thin wrapper around the Windows API DrawText() function so you can calculate the size of the area needed to render the text into.

<QUOTE>Please can you then advise what fields  and  are for in the TEXTRECT service, the documentationstates:



 Refer to SDK DrawText() (Format parameter)

 Width of rectangle for DT_WORDBREAK flag set (only if object doesn't exist)



Thanks

<QUOTE>Oh, I have also tried setting up DrawText as a DLL declaration in User32.DLL.



The RECT parameter seems to be a problem.

Any suggestions as what the declarations might be.

MSDN states:



int DrawText(

  __in     HDC hDC,

  __inout  LPCTSTR lpchText,

  __in     int nCount,

  __inout  LPRECT lpRect,

  __in     UINT uFormat

);
