Inserting a string with CRLF into a single-line TGet.

[Natter]

Hi,

In the document, I select a line consisting of 2 parts separated by the characters CRLF or chr(10)
and copy it to the clipboard. Next, I want to paste the information from the clipboard into a one-line TGet.
However, only the first part of the phrase (before CRLF) will be inserted. How can I solve this problem?

Just replace (using STRTRAN()) CRLF with a space or something else you like.

Quiza con la funcion AT

cCAD="abcdfe"+crlf+"12345"

cCAD2=SUBSTRING(cCAD,1,AT(CHR(10),cCAD)-1)

Can you provide a working sample?

Algo asi?

Code: Select all  Expand view

#include "FiveWin.ch"

FUNCTION Main()

   LOCAL cText, cVar

   cText := "Teste1 " + CHR( 10 ) + " Teste2" + CHR( 9 ) + " Teste3 " + ;
            CHR( 25 ) + CHR( 13 ) + CHR( 10 )

   ? LEN( cText )

   ? cText

   cText := ClearString( cText )

   ? LEN( cText )

   ? cText

   cVar := StrTran( HardCR(  AllTrim( cText ) ), Hb_EOL() )

   ? cVar

   cVar := SUBST( cText, 1, AT( CHR(10), cText )-1 )

   ? cVar

RETURN NIL

FUNCTION ClearString( cString )

   LOCAL cNewString
   LOCAL n

   cNewString := ""

   FOR n := 1 TO LEN( cString )

      IF asc( substr( cString, n, 1 ) ) == 9 // TAB

         cNewString += CHR( 32 )

      ELSEIF asc( substr( cString, n, 1 ) ) >= 32

         cNewString += substr( cString, n, 1 )

      ENDIF

   NEXT n

RETURN cNewString

// FIN / END
 

Regards, saludos.

All this is ok, as long as you know the text.
And substitution by itself is a simple one line code.

The user copies some text from some other window or application or a webpage by pressing Ctrl-C or by selecting Copy from the context
And as a programmer you do not know what text the user will copy.

And when the user wants to paste in the Get, he presses Ctrl-V or selects "Paste" from the right-click context menu.
Then the TGet class calls:

Code: Select all  Expand view

CallWindowProc( ::nOldProc, ::hWnd, WM_PASTE, 0, 0 )

Now the Windows OS reads the text from the Clipboard and Pastes in the Get buffer. While doing so the Windows OS truncates the string from CRLF onwards.

How and when do you apply to what text your logic of substituting CRLF or TAB ?
So, no point giving program to replace CRLF.
Give a program where if I copy whatever text which includes CRLF and paste in the Get, I will get all the text excepting the CRLF.

I suggest this quick solution for your immediate use.
You need to write it for each Get.

Sample logic:

Code: Select all  Expand view

  DEFINE DIALOG oDlg SIZE 400,400 PIXEL TRUEPIXEL

   @ 20,20 GET oGet1 VAR cVar1 SIZE 300,24 PIXEL OF oDlg
   oGet1:bKeyDown := { |k| If( k == ASC("V") .and. GetKeyState( VK_CONTROL ), CheckCRLF(), ) }

   // other code

//--------------------

function CheckCRLF()

   local cText := FW_GetClipboardData()

   if ValType( cText ) == "C"
      cText := StrTran( StrTran( cText, CRLF, " " ), Chr(10), " " )
   endif
   FW_CopyToClipboard( cText )

return nil


 

We are peeking into the ClipBoard and putting back modified string again into the clipboard just before the Windows OS reads it. Now Windows OS reads the modified string.



Note:
Limitations:
1. This is working with ANSI gets only. Not working reliably with Unicode gets. We are looking into it.
2. This works if the user pastes by pressing Ctrl-V. Does not work if the user pastes by selecting "Paste" menu option in the popup context menu. This needs modification of HandleEvent method of TGet class.

Hope this works for now.

[Enrico Maria Giordano]

Yes, you are right. I did not consider the "paste" problem, sorry.

[Natter]

Thank you, Rao, a good solution !
Please explain such points:
1. Why write oGet1:bKeyDown :={ |k|If( k == ASC("V") .and. GetKeyState(VK_CONTROL ), Check CRL F(), ) }
for each control if the method can be modified :KeyDown via Override ?
2. Will this function work when entering data from the clipboard via the context menu ? Can use :bChange and check which way to make these changes ?

1. Why write oGet1:bKeyDown :={ |k|If( k == ASC("V") .and. GetKeyState(VK_CONTROL ), Check CRL F(), ) }
for each control if the method can be modified :KeyDown via Override ?

With override, the change applies to all Gets and we need not write this for each Get.
If you like, you can override the method till next version. t

2. Will this function work when entering data from the clipboard via the context menu ?

For this, we need to modify/override the method HandleEvent.

Can use :bChange and check which way to make these changes ?

No use at all. By this time, Windows OS has already read the Clipboard contents and completed the paste operation truncating the text from CRLF onwards. We have no way to know what is the original text.
