Continuous RichEditHighlight
#1
Hi Gintaras,
Hope all is well!
I am trying to monitor continuously in text for the occurrence of certain string and then highlight it (as the user types). Simplified example below. Problem is that RichEditHighlight moves cursor back to starting position each time because of EM_SETSEL 0 0 message. Therefore can not have continuous typing because cursor position changes, etc.

Any thoughts on how to get around this?

Thanks for any thoughts,
Stuart

In RichEditHighlight replace several last lines to
Function RichEditHighlight
Code:
Select All      Help
int selStart selEnd
SendMessage hwndre EM_GETSEL &selStart &selEnd

for i 0 a.len
,SendMessage hwndre EM_SETSEL a[0 i].cpMin a[0 i].cpMax
,SendMessage hwndre EM_SETCHARFORMAT SCF_SELECTION m.address

SendMessage hwndre EM_SETSEL selStart selEnd
ret a.len

Thanks Gintaras for this successful answer.
With this version of RichEditHighlight, I can almost make a continuously format-updating tool without changing the cursor position i.e. if i type the phrase "the ball is red" then as soon as findrx finds red, it will change the text to red, even as I go on to type additional text.
But the problem is that it gets glitchy because it keeps on trying to re-apply the formatting to previous instances which have already been turned red. Is it possible to determine whether some formatting, whether it be bold, underline, italicize or text/background color is already true before applying? I tried below using getsel with the CF_RTF limited to the offsets of interest. It works in theory, but it is so jumpy it makes interaction and typing practically impossible. Is there any way to make this more of a background process for the user?
I know from http://www.quickmacros.com/forum/showthr...p?tid=1406 that I could use GetRTF with SendMessage(hre EM_STREAMOUT SF_RTF &es) but the application with the RichEdit control is external so I would need to do the dll injection via hook that you described in the other thread. If there is not a way to salvage the code below, could you suggest how I could do the dll injection. The external app is 32-bit. I work with some folks who could do the C programming if I could just give them some of the details.
Any advice?
Thanks so much, S

I found this in QM Scripting folder: __Tcc --> C example - global hook in dll  (pasted below).
I just don't know how to modify this to allow me to use the GetRTF function from  http://www.quickmacros.com/forum/showthr...p?tid=1406
The child richedit text element is pretty straightforwawrd - i.e. with text extractable by .getwintext via child definition of 


Code:

child("" "*.RICHEDIT50W.*" hWnd 0x0 "wfName=rtbReport") ;;editable text

Any advice?

I don't know other ways to get RTF and how to improve this code.
Dll injection - not QM-specific. Need to create a dll in Visual Studio, using C++ language. Inject it with SetWindowsHookEx(WH_CALLWNDPROC, HookFunctionInThisDll, ModuleHandleOfThisDll, ThreadIdOfTheWindow) and SendMessage(hwnd, MyMessage, 0, 0). Then to send data back use eg shared memory or ReadProcessMemory.

Thanks so much! I will see what I can do with your suggestions.

...

With __Tcc possible but much much more difficult than with Visual Studio. No intellisense, no C++, no 64-bit, no exception handling. It is reasonable only for simple small code. Injecting dll, getting RTF and passing it back is not so easy. I cannot help.

Visual Studio Community 2017 is free. It's the best IDE. But it takes maybe 10 GB. If it's too much, you can find a smaller IDE that supports C++.

The function is very simple, easy to convert to C++. Or maybe better look for an EM_STREAMOUT example eg in stackoverflow.

That is all very helpful. I am downloading Visual Studio now.
