Code:
Select All      Help
str rx="find this"
int flags=1 ;;1 insens, 2 whole word

int h=id(15 "Notepad")
int i length
int+ g_newsearch
str s.getwintext(h); if(!s.len) ret ;;get all text
if(!g_newsearch) SendMessage(h EM_GETSEL 0 &i) ;;get caret pos
i=findrx(s rx i flags|8 length)
if(i<0) g_newsearch=1; mes- "Not found."
g_newsearch=0

Thanks.

Is it possible highlight all ocurrences?

No, but I think in wordpad it is possible.

Using EM_SETCHARFORMAT messages. Use share for CHARFORMAT2 structure.

How: Use share for CHARFORMAT2 structure?

I tried

found=SendMessage(share(re) EM_FINDTEXT FR_DOWN &editfind)

and Wordpad crash.

Something like this:

Code:
Select All      Help
CHARFORMAT2W* sm_in_wordpad=+share(worpad_edit_control_handle)
CHARFORMAT2W* sm_in_qm=+share
sm_in_qm.some_member=some_value
;...
SendMessage worpad_edit_control_handle EM_SETCHARFORMAT SCF_SELECTION sm_in_wordpad)

I don't think you need EM_FINDTEXT if you use regular expressions. I don't think you should convert the sample as it is.
Reply

Maybe better open the text in a web browser and use a bookmarklet capable to find/highlight text using regular expressions. You'll find such bookmarklets on the Internet. Search for bookmarklet highlight regular expression.

Why do you use share(re) where window handle mus be Confusedhock:
Never pass address of a variable to other applications. Use
VARIABLETYPE* variable=+share
variable.member=value
...
SendMessage re ... share(re)
Reply
#13
On Windows XP, wordpad edit control class is richedit50w. The w at the end means that you must use wide character versions of structures, eg CHARFORMATW.

Note 2:
If you use EM_FINDTEXT, FINDTEXT lpstrText member must point to string that is in shared memory.
Reply

I never had been used SHARE, and in the help:

Return pointer to shared memory

can you help me in the case 6 to highlight all find words in any editbox?

Hi,
I would like to highlight text within a RichEdit20W field. After highlighting it, I would like to delete it - i.e. I am only highlighting it to be able to send a delete keystroke.


Code:
Select All      Help
int handw=GetWinId(child("" "WindowsForms10.RichEdit20W.app.0.378734a" win("Sample App" "WindowsForms10.Window.8.app.0.378734a") 0x5))
RichEditHighlight handw "find this"


Anyway, everytime I do it, the appropriate text gets highlighted but then I get the following errors:


Quote:An Unexpected Error Occurred:
Exception has been thrown by the target of the invocation.
Click Retry or Cancel to terminate the application


If I click "Retry", the text becomes unhighlighted and the dialog disappears. If I hit "Cancel", I get the following message:

Quote:A fatal error occurred and the application will now terminate:
COM returned an unexpected error code: Details are RPC_E_CANTCALLOUT_ININPUTSYNCCALL


When I press OK, the dialog goes away but the application of the RichEdit field doesn't close, though the text remains unhighlighted.

I hope this explanation helps and that there is a solution. In the meantime, I will research what Richedit20W means - I see you have previously referred to RichEdit and RichEdit20 but not RichEdit20.

Thanks,
Stuart

The function works with RichEditXXW too. Don't know why the target app crashes. I tested with Wordpad on XP and Vista. But if you need to select text for deleting or replacing, this function does not do it. It only changes colors. See this:

Hi Gintaras,
I have a complex dialog that uses RichEditHighlight and would lilke to make exe out of it. It works when I comment out all the RichEditHighlight lines but when they are in place I get this error:

Error in SampleDialog: cannot be used in exe.
Cannot make exe. Error 4, failed to compile.

The location of the error is in the following line of the RichEditHighlight function:

Function RichEditHighlight_RefsManager
Code:
Select All      Help
memset(share 0 sizeof(CHARFORMAT2W))

This is such a great function that I hope it will be incorporated into the main version of QM and supported in the exe.

Thanks for any thoughts on this! As always, DEEPLY grateful for all your help!!

Hi Gintaras,
Thanks for the update on RichEditHighlight. It no longer is stopping the creation of the exe. However the dialog specified in my folder of macros is still not launching. At time of exe creation, I get this message:

Quote:Warning: Cannot find function GetProcessHandleFromHwnd in dll oleacc. Make sure it is available when the code runs. Make sure the declaration contains true function name.
Created C:\Documents and Settings\xxx\My Documents\My QM\SampleProgram.exe, 735 KB. Run Find


When I attempt to run the exe, I get this:
Quote:Error (RT) in SampleProgram: cannot show dialog

I know this is very generic and it may be hard for you to help me with such little to go on. The dialog and associated user-defined functions it calls are very complex so it will be a challenge for me to rebuild it piece by piece confirming working exe each time (but I will do it that way if necessary). I was just wondering if there were some typical things that may cause a dialog to not launch in an exe.

The issue with GetProcessHandleFromHwnd in dll oleacc did not stop a much simpler function from running properly after converted into an .exe so I don't think it is just that.


Thanks so much for any help you can give me,

Stuart

Hi Gintaras,
I realized that the main dialog uses the splitters which required InitSplitter to create the QM_Splitter class. Is this something that is incompatible with exe. Is there a way to place to register the window class "QM_Splitter" when launching an exe?

Thanks..I hope this is helpful in answering my previous question.

Stuart
Reply
#27
Yes, it was definitely the splitters. I took them out of the dialog, made the exe and it ran fine!!
Hope there is a solution to including this class into exe
Thanks!!!
Stuart
Reply
#28
Call InitSplitter in your main exe function.

-------------

Ignore the GetProcessHandleFromHwnd warning. Exe will find and use it on Windows Vista/7.

Next QM will not show such warnings for dll functions declared in System.
