hi,

I try to create a Snippet manager, for do that i send key to the external application.
The problem is some application have several tab, and even if i enumerate the class into this application i'm not sure to send the text to the good tab.

Have you a way for obtain the handle where the cursor is ??

Best regards

Thanks for your answer.
The SendKey works, it's the most simple method

But i believe, i need a little bit of help for the sendmessage, i don't know how use this API

And i have search RealChildWindowFromPoint on the forum, the only one answer is your post

Code: Select all

Hwnd = FindWindow_(0, "*Untitled1 - Code::Blocks 10.05")
; SendKey method (Works)
SetForegroundWindow_(Hwnd)
keybd_event_(#VK_H, 0, 0, 0)
keybd_event_(#VK_H, 0, #KEYEVENTF_KEYUP, 0)
Delay(10)
keybd_event_(#VK_E, 0, 0, 0)
keybd_event_(#VK_E, 0, #KEYEVENTF_KEYUP, 0)
Delay(10)
keybd_event_(#VK_L, 0, 0, 0)
keybd_event_(#VK_L, 0, #KEYEVENTF_KEYUP, 0)
Delay(10)
keybd_event_(#VK_L, 0, 0, 0)
keybd_event_(#VK_L, 0, #KEYEVENTF_KEYUP, 0)
Delay(10)
keybd_event_(#VK_O, 0, 0, 0)
keybd_event_(#VK_O, 0, #KEYEVENTF_KEYUP, 0)
Delay(10)

; SendMessage method
GetCursorPos_(@p.POINT)
ScreenToClient_(Hwnd, @p)
Debug p\y
Debug p\x
Object = RealChildWindowFromPoint_(Hwnd, p\y<< 32+p\x)
SendMessage_(Object, #WM_SETTEXT, 0, @"Goodbye")

I tried with this code, the word goodbye is sent, but the caption panel codeBlock before called "SCIwindow" is now called "goodbye"

The text is not sending to the cursor

Code: Select all

Procedure EnumChildProc(hwnd, lParam)
 
 If hwnd
  result  = 1
  tLen = SendMessage_(hwnd, #WM_GETTEXTLENGTH, 0, 0)
  text$ = Space(tLen)
  SendMessage_(hwnd, #WM_GETTEXT, tLen + 1, @text$)
  If Trim(Text$) <>""
   Debug text$
  EndIf
  
  If Trim(Text$) = "SCIwindow"
   SetForegroundWindow_(Hwnd)
   SendMessage_(hwnd, #WM_SETTEXT, 0, @"Goodbye")
  EndIf 
  
 Else
  result = 0
 EndIf
 
 ProcedureReturn result
 
EndProcedure

hwnd = FindWindow_(0,"*Untitled1 - Code::Blocks 10.05")

If hwnd
 EnumChildWindows_(hwnd, @EnumChildProc(), hwnd) 
EndIf

Nobody can help me ?
My program works with items like keys CTRL+C / CTRL+V and also with sending each character.
But I would have loved to have the direct method sending a text, if it is possible of course.

To show you what I've done, here's a draft of my program.
It is super simple to use, well I hoped

1 / Choose the IDE text you want to copy a SNIPPET "NotePad, NotePad++, CodeBlock, PB IDE, VC, etc. .." and put the cursor at the position where you want to copy SNIPPET
2 / Starting the program (Attention at the beginning the program is in the systray, you can modify like you want after)
3 / Click on "Select window"
4 / Click on the title bar of the selected IDE (The title should appear in the combo box at the bottom)
You can also directly select in the combo box if you don't want select by the mouse
5 / SNIPPET Select one of the categories in the TreeGadget (For each snippet selected, the comment appears at the bottom of the window)
6/ Double click it, the text should normally appear in your favorite IDE

- It is therefore for the moment, send the text by two different methods
- You can position the window of four ways (On the left side, she hides automatically as in the PB IDE, or in the systray, or free modal or free no-modal)
- You can adjust the speed at which it hides
- You can also choose the language

To do list
Find how to send a text cursor with the API (SendMessage or other)
The creation / deletion of snippets and classes
Detection of the language use (C, PB, Html, etc ...)
Make it pretty (icons, skins, etc ...)
And maybe other ideas along the way (From you or me, of course

) mainly if i can

Thank you for your interest.

Apparently my project does not interest many people.

I progressed through a code of FWEIL, I can now list the classes and thanks to DIGGER I can focus on the good.
It remains problematical and not least, I still do not know how to detect the object in focus, so whoever at the cursor when the window gets focus
In VC + + 2005, for exampler, all tabs have the same name of class, and my text is sent in each.

Someone he would pity a beginner ??

I'm not sure I understand exactly what it is you're attempting, but if you are attempting to capture keystrokes in another application so you can add/switch the text, you might want to investigate a keyboard hook. There are examples in the forums, but it's not exactly a beginner project.

cheers

Have you try the exe in the link ???
If you try it you understand what i want to do

I want just can copy text in another application and paste it in PB appli, and of course the opposite.

Since yesterday i have found another way to send text to another application.
It's again a code of Netmaestro

using SendInput API, and that works great.
http://www.purebasic.fr/english/viewtop ... 87#p289987
I'll add this method in my combobox of methods
Send text has an external program is not very reliable, so I'll put all the possible methods, how the user can choose the one that suits him best.

I have now this methods:
KeybEvent key by key method (Works but if the text is long, the user must not touch the keyboard, while sending text)
ClipBoard CTRL KeybEvent c+v (Works, but the clipboard is used, and if the user have something into it...it is lost)
ClipBoard Sendmessage WM_PASTE method (Works, but the clipboard is used, and if the user have something into it...it is lost)
SendInput method (Works, i don't now if the user can disturb while the sending of the text ??)
Sendmessage WM_CHAR method (I have not found again, how send #CRLF$, and lowercase) if someone know ??
