The MASM Forum

    Hey... so i'm looking into putting text search on my app for mdichild windows and registered "FINDMSGSTRING but it doesn't appear on any window procudures of the app. why would that be? i've even tried to subclass the findtext dialog and still no sign of FINDMSGSTRING. Can someone gimme an example of its use please? Thanks

   why does this not work?

Where does what not work?

Hi xandaz

Read the manual:

QuoteYou must specify the FINDMSGSTRING constant in a call to the RegisterWindowMessage function to get the identifier for the message sent by the dialog box.

Delete these lines:
FINDMSGSTRING   dd      0
UCSTR      fmsgs,"FINDMSGSTRING",0

Insert something like this:
uFindReplaceMsg    DWORD    0    ; Store the return value of RegisterWindowMessage in this variable

Call RegisterWindowMessage like this:
invoke  RegisterWindowMessage, addr CStr(FINDMSGSTRING)
If FINDMSGSTRING is not defined in your windows header files:
invoke  RegisterWindowMessage, addr CStr("commdlg_FindReplace")

Read the next paragraph of the manual:

QuoteWhen you create the dialog box, use the hwndOwner member of the FINDREPLACE structure to identify the window to receive FINDMSGSTRING messages.

FINDMSGSTRING message (https://docs.microsoft.com/en-us/windows/win32/dlgbox/findmsgstring)

See example: Using Common Dialog Boxes - Finding Text (https://docs.microsoft.com/en-us/windows/win32/dlgbox/using-common-dialog-boxes#finding-text)

Kind regards

   Thanks a lot. It worked like a charm. So it's "commdlg_FindReplace". Thanks a lot. Really guys.

   Hi guys. I've been trying to get the FindText thing to work properlly but i'm having some issues. What would be the best way to srcoll the text selection into view. I've been trying EM_CHARFROMPOS and EM_SETSCROLLPOS but it doesn't work so welll. Isn't there a way to move line into the selected text automatically? Thanks in advance

   Here is the code:
.if edx==FINDMSGSTRING
invoke SendMessage,hMdi,WM_MDIGETACTIVE,0,0
invoke GetWindowLong,eax,GWL_USERDATA
mov edi,eax
mov esi,lParam
test [esi.FINDREPLACE.Flags],FR_DIALOGTERM
jnz exit_1
invoke SendMessage,[edi.MdiStruct.hEdit],EM_HIDESELECTION,TRUE,0
invoke SendMessage,[edi.MdiStruct.hEdit],EM_EXSETSEL,0,addr crange
invoke SendMessage,[edi.MdiStruct.hEdit],EM_EXGETSEL,0,addr crange
push crange.cpMin
pop ft.chrg.cpMin
push crange.cpMax
pop ft.chrg.cpMax
mov lr,rv(SendMessage,[edi.MdiStruct.hEdit],EM_FINDTEXTEX,FR_DOWN,addr ft)
mov ft.chrg.cpMin,eax
.if lr>=0
inc lr
push lr
pop crange.cpMin
mov crange.cpMax,-1
exit_1:
invoke SendMessage,[edi.MdiStruct.hEdit],EM_POSFROMCHAR,addr pt,crange.cpMin
invoke SendMessage,[edi.MdiStruct.hEdit],EM_SETSCROLLPOS,0,addr pt
invoke SendMessage,[edi.MdiStruct.hEdit],EM_EXSETSEL,0,addr ft.chrgText
invoke SendMessage,[edi.MdiStruct.hEdit],EM_HIDESELECTION,FALSE,0
mov eax,TRUE
ret
.endif
mov eax,FALSE
ret


EM_SCROLLCARET?

   Ok. I'll try that. Thanks. It worked. I thought i tried that but no. Thanks a lot JJ.

    Hi guys. I'm having a hard time solving a little problem. invoke ClearMemory,addr FindReplace,sizeof FindReplace
push hWnd
pop FindReplace.hwndOwner
mov FindReplace.lStructSize,sizeof FINDREPLACE
push hInstance
pop FindReplace.hInstance
mov FindReplace.Flags,FR_DOWN or FR_FINDNEXT
mov FindReplace.lpstrFindWhat,offset FindString
mov FindReplace.lpstrReplaceWith,offset ReplaceString
invoke FindText,addr FindReplace

    Returns NULL but CommDlgExtendedError doesnt return any valid error code. 16385 tobe precise
