Use GET MEMO

[vilian]

Mr Rao,

I tried with MemoEdit() but its allows the user to change the content and I only wants to show the content.

[cnavarro]

Use clause READONLY

[vilian]

Ok,

I was thinking that FWH had a user quick dialog box. I will create a dialog and use GET MEMO to show it.

[nageswaragunupudi]

Code: Select all  Expand view  RUN

function ShowText( cText )

   local oDlg

   DEFINE DIALOG oDlg SIZE 600,300 PIXEL TRUEPIXEL
   @ 20,20 GET cText MEMO SIZE 560,260 PIXEL OF oDlg READONLY
   ACTIVATE DIALOG oDlg CENTERED

return nil

Thank you

Please also try this interesting function

Code: Select all  Expand view  RUN

  local oWnd

   DEFINE WINDOW oWnd

   @ 20,20 BUTTON "Show Text" SIZE 80,30 PIXEL OF oWnd ;
      ACTION HTMLPOP( GetActiveWindow(), nil, 0x000E, MEMOREAD( "c:\fwh\samples\tutor01.prg" ) )

   ACTIVATE WINDOW oWnd CENTERED

I'm not sure what you are seeking.

I do have some memo fields within a dialog that users want both more space to edit ( so they can see more than what fits in the control space), and a larger font. I have a button that pops up a dialog using a larger size, and a larger font. It's popular.

Mr Vilian just wants to display medium-sized multi-line text without editing. We provided a basic sample. What font and size he likes and what size of dialog he wants he will decide and implement depending on his requirements.

Here is a simple function I created. You can pass any text variable ( cLabTxt ) to it, call it with a button or other command ( ie. you could do a double click with a field to call it ), and it pops up a dialog box. The text is bold ( darker ) and larger, and it provides more editing space.

This is just another sample of a way to do the work you wish.

Code: Select all  Expand view  RUN

FUNCTION ExpandText( cLabTxt )

  LOCAL oXTxt, oGt1, oBarExp
  LOCAL aPubGrad := { | lInvert | If( ! lInvert, { { 0.50,16776960,16777215 }, ;
                    { 0.50,16777215,16776960 } }, { { 0.50,128,16777215 }, { 0.50,16777215,128 } } ) }   // HCYAN, WHITE ; RED, WHITE
  DEFINE FONT oLfont NAME cSysFont SIZE 0,-14 BOLD
 
 DEFINE DIALOG oXTxt RESOURCE "EXPTXT" BRUSH oBrush transparent OF oWnd FONT oLFont

    REDEFINE GET oGt1 VAR cLabTxt MEMO ID 8522 OF oXTxt
        oXTxt:bStart = { || oGt1:GoBottom() }

    REDEFINE BUTTONBAR oBarExp ID 100 SIZE 60,60 OF oXTxt 2015
    oBarExp:bClrGrad := aPubGrad
    DEFINE BUTTON oBtnEx1 OF oBarExp RESOURCE "HROK"  PROMPT "OK" ACTION ( oXTxt:end()) ;
        MESSAGE "Make your changes and press OK"
    DEFINE BUTTON oBtnEx2 OF oBarExp RESOURCE "SPELL" PROMPT "Spell" TOOLTIP "Spell check text" ;
        ACTION ( cLabTxt := SpellOne( cLabTxt ), oGt1:refresh( ) ) NOBORDER TRANSPARENT
       
    ACTIVATE DIALOG oXTxt ON INIT  oBarExp:lTransparent := .F. CENTERED
       
RETURN( cLabTxt )
 

Here is the .rc code:

Code: Select all  Expand view  RUN

EXPTXT DIALOG 0, 0, 660, 410
STYLE WS_POPUP | WS_CAPTION
CAPTION "Text Editor"
{
    CONTROL                 "", 100, "TBar", 0|WS_CHILD|WS_VISIBLE, 0,0, 660, 30
    EDITTEXT        8522,10,40,640,360,ES_MULTILINE | ES_WANTRETURN | WS_VSCROLL
}

How long (bytes) ?

Hi,

If we have more 30000 bytes, memoedit readonly does not show. I dont use memo fields (dbfcdx) in this situation. Just use to show and add some characters (Append method) with other button. save it with another method.

Code: Select all  Expand view  RUN

oNots:Append(CRLF+CRLF+DTOC(DATE())+" - "+TIME()+" - "+         ALLTRIM(xUSERNAME+CRLF+REPLICATE("-",60)+CRLF+ALLTRIM(cText))

Any solution?

[nageswaragunupudi]

If we have more 30000 bytes, memoedit readonly does not show.

If you are using FWH2006, even larger text is displayed without any limit.
(Note: MEMOEDIT function is renamed as FW_MEMOEDIT)
