BrettF Posted June 24, 2009 Share Posted June 24, 2009 Well if your using a monospace font, then split the string by character lengths and then reconstruct it... Otherwise you might need to get a total width for each line etc. Vist my blog!UDFs: Opens The Default Mail Client | _LoginBox | Convert Reg to AU3 | BASS.au3 (BASS.dll) (Includes various BASS Libraries) | MultiLang.au3 (Multi-Language GUIs!)Example Scripts: Computer Info Telnet Server | "Secure" HTTP Server (Based on Manadar's Server)Software: AAMP- Advanced AutoIt Media Player | WorldCam | AYTU - Youtube Uploader Tutorials: Learning to Script with AutoIt V3Projects (Hardware + AutoIt): ArduinoUseful Links: AutoIt 1-2-3 | The AutoIt Downloads Section: | SciTE4AutoIt3 Full Version!

Moderators Melba23 Posted July 8, 2009 Moderators Share Posted July 8, 2009 seesoe,If you know the width of the page you want to print relative to the screen pixels, then this UDF which wraps the text might work for you. It was designed to wrap a long string to fit into messageboxes and labels with a set width, but I think you could adapt it to do what you want. The wrapped string itself is the [0] element of the returned array.expandcollapse popup#include-once #include <WindowsConstants.au3> #include <SendMessage.au3> #include <WinAPI.au3> ; #FUNCTION# ======================================================================================= ; ; Name...........: _StringSize ; Description ...: Returns size of rectangle required to display string - width can be chosen ; Syntax ........: _StringSize($sText[, $iSize[, $iWeight[, $iAttrib[, $sName[, $iWidth]]]]]) ; Parameters ....: $sText - String to display ; $iSize - Font size in points - default AutoIt GUI default ; $iWeight - Font weight (400 = normal) - default AutoIt GUI default ; $iAttrib - Font attribute (0-Normal, 2-Italic, 4-Underline, 8 Strike - default AutoIt ; $sName - Font name - default AutoIt GUI default ; $iWidth - [optional] Width of rectangle - default is unwrapped width of string ; Requirement(s) : v3.2.12.1 or higher ; Return values .: Success - Returns array with details of rectangle required for text: ; |$array[0] = String formatted with @CRLF at required wrap points ; |$array[1] = Height of single line in selected font ; |$array[2] = Width of rectangle required to hold formatted string ; |$array[3] = Height of rectangle required to hold formatted string ; Failure - Returns 0 and sets @error: ; |1 - Incorrect parameter type (@extended = parameter index) ; |2 - Failure to create GUI to test label size ; |3 - Failure of _WinAPI_SelectObject ; |4 - Font too large for chosen width - longest word will not fit ; Author ........: Melba23 ; Modified ......: ; Remarks .......: ; Related .......: ; Link ..........: ; Example .......: Yes ;=================================================================================================== Func _StringSize($sText, $iSize = Default, $iWeight = Default, $iAttrib = Default, $sName = Default, $iWidth = 0) Local $hWnd, $hFont, $hDC, $oFont, $tSize, $hGUI, $hText_Label, $sTest_Line Local $iLine_Count, $iLine_Width, $iWrap_Count, $iLast_Word Local $asLines[1], $avSize_Info[4], $aiPos[4] ; Check parameters are correct type If Not IsString($sText) Then Return SetError(1, 1, 0) If Not IsNumber($iSize) And $iSize <> Default Then Return SetError(1, 2, 0) If Not IsInt($iWeight) And $iWeight <> Default Then Return SetError(1, 3, 0) If Not IsInt($iAttrib) And $iAttrib <> Default Then Return SetError(1, 4, 0) If Not IsString($sName) And $sName <> Default Then Return SetError(1, 5, 0) If Not IsNumber($iWidth) Then Return SetError(1, 6, 0) ; Create GUI to contain test labels, set to passed font parameters $hGUI = GUICreate("", 1200, 500, 10, 10) If $hGUI = 0 Then Return SetError(2, 0, 0) GUISetFont($iSize, $iWeight, $iAttrib, $sName) ; Store unwrapped text $avSize_Info[0] = $sText ; Ensure EoL is @CRLF and break text into lines If StringInStr($sText, @CRLF) = 0 Then StringRegExpReplace($sText, "[x0a|x0d]", @CRLF) $asLines = StringSplit($sText, @CRLF, 1) ; Draw label with unwrapped lines to check on max width $hText_Label = GUICtrlCreateLabel($sText, 10, 10) $aiPos = ControlGetPos($hGUI, "", $hText_Label) GUICtrlDelete($hText_Label) ; Store line height for this font size after removing label padding (always 8) $avSize_Info[1] = ($aiPos[3] - 8)/ $asLines[0] ; Store width and height of this label $avSize_Info[2] = $aiPos[2] $avSize_Info[3] = $aiPos[3] - 4 ; Reduce margin ; Check if wrapping is required If $aiPos[2] > $iWidth And $iWidth > 0 Then ; Set returned text element to null $avSize_Info[0] = "" ; Set width element to max allowed $avSize_Info[2] = $iWidth ; Set line count to zero $iLine_Count = 0 ; Take each line in turn For $j = 1 To $asLines[0] ; Size this line unwrapped $hText_Label = GUICtrlCreateLabel($asLines[$j], 10, 10) $aiPos = ControlGetPos($hGUI, "", $hText_Label) GUICtrlDelete($hText_Label) ; Check wrap status If $aiPos[2] < $iWidth Then ; No wrap needed so count line and store $iLine_Count += 1 $avSize_Info[0] &= $asLines[$j] & @CRLF Else ; Wrap needed so need to count wrapped lines ; Create label to hold line as it grows $hText_Label = GUICtrlCreateLabel("", 0, 0) ; Initialise Point32 method $hWnd = ControlGetHandle($hGui, "", $hText_Label) $hFont = _SendMessage($hWnd, $WM_GETFONT) $hDC = _WinAPI_GetDC($hWnd) $oFont = _WinAPI_SelectObject($hDC, $hFont) If $oFont = 0 Then Return SetError(3, 0, 0) ; Zero counter $iWrap_Count = 0 While 1 ; Set line width to 0 $iLine_Width = 0 ; Initialise pointer for end of word $iLast_Word = 0 For $i = 1 To StringLen($asLines[$j]) ; Is this just past a word ending?

seesoe Posted July 8, 2009 Author Share Posted July 8, 2009 (edited) interesting i really dont understand how the page width and all that stuff works with the print udf, but i found this in the udf ;_PrintGetPageWidth ;parameters - $hDll, the handle for printmg.dll ;returns page width in tenths of a millimetre and @error = 0 ; ;on failure returns -1 and @error = 1 Func _PrintGetPageWidth($hDll) $vDllAns = DllCall($hDll,'int','GetPageWidth') If @error = 0 Then Return $vDllAns[0] SetError(1) Return -1 EndFunc Edited July 8, 2009 by seesoe Link to comment Share on other sites More sharing options...
seesoe Posted July 10, 2009 Author Share Posted July 10, 2009 so we have page width from the print udf in millimeters, do i use the word wrapping udf for info on how to split the text or the actually split of the text? im not sure i get how to proceed in trying to write the code Link to comment Share on other sites More sharing options...
martin Posted July 10, 2009 Share Posted July 10, 2009 so we have page width from the print udf in millimeters, do i use the word wrapping udf for info on how to split the text or the actually split of the text? im not sure i get how to proceed in trying to write the codeThe print udf has functions to tell you the width and height of text. So if you have a string can select the next word, see if it will fit in the line and if it does then add it to the current line, if it doesn't fit then print the last line and start a new one.I think Prg@ndy has written a printing function to deal with word wrapping using API calls. Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.

seesoe Posted July 10, 2009 Author Share Posted July 10, 2009 (edited) @martin, is there any chance that you will ever be adding text wrap to your udf? Edited July 10, 2009 by seesoe Link to comment Share on other sites More sharing options...
