Sendmessage function. ELP

8 posts in this topic

Hi guys, im trying to making _sendmessage function works like controlclick and controlsend.

Im testing it in a random program compiled in vb6 by me.

Here is the code:

#RequireAdmin

#include <SendMessage.au3>


Opt("WinTitleMatchMode", -1)


HotKeySet("{F2}", "GG")

Func GG()
Local const $BM_CLICK = 0X201
    Local $hWnd = WinWait("[CLASS:ThunderRT6FormDC]", "")
    Local $hControl = ControlGetHandle($hWnd, "TEST BY GUYBRUSH", "ThunderRT6PictureBoxDC5")

;THIS WORKS FINE WITH CONTROLCLICK AND CONTROLSEND.
ControlClick($hWnd, "TEST BY GUYBRUSH", "ThunderRT6PictureBoxDC5", "Left", 2, 19, 14)
ControlSend($hWnd, "TEST BY GUYBRUSH", "ThunderRT6PictureBoxDC5", "U")
;I want to do that with _sendmessage, instead of controlclick and controlsend.

;I have tried:

_Sendmessage($hControl , $BM_CLICK, 19,14)
_Sendmessage($hwnd,"TEST BY GUYBRUSH", $BM_CLICK, 19,14)
;i have no idea how to send a key with _sendmessage either.
;Nothing seems to works
EndFunc

I want to do:

ControlClick($hWnd, "TEST BY GUYBRUSH", "ThunderRT6PictureBoxDC5", "Left", 2, 19, 14)
ControlSend($hWnd, "TEST BY GUYBRUSH", "ThunderRT6PictureBoxDC5", "U")

 

with _sendmessage instead of CONTROLclick and controlsend.

I have read sendmessage function but still cant get the concept.

I aprecciate your help, thanks guybrush

What window message is $BM_CLICK?

Read this to understand how to send a left button click to a window. Once you've sent your WM_LBUTTONDOWN you have to send WM_LBUTTONUP to complete the click.

I believe there's a mouseclickplus udf somewhere around the forum too. You could try searching for that and see how they did it.

How you declare them ?
Do you use $ char ?
Why you are not using $ char in your example ?

I'm not surprised that you think that doesn't work.

19 is your wparam, 14 is your lparam. According the link I told you to read

Quote

wParam

Indicates whether various virtual keys are down. This parameter can be one or more of the following values.

lParam

The low-order word specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.

The high-order word specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.

The LoWord of 14 is 14, the HiWord of 14 is 0, so your clicked at 14, 0. And Hex of 19 is 0x13, that doesn't look like any of the available wParams according to msdn. Though it doesn't really matter for what you're trying to do.

Thanks for your help taishou.

 

Right now i got this:

 

#RequireAdmin

#include <SendMessage.au3>


Opt("WinTitleMatchMode", -1)


HotKeySet("{F2}", "GG")

While 1
    Sleep(10)
WEnd

Func GG()

Local $MK_LBUTTON = 0x0001
Local $WM_LBUTTONDOWN = 0x0201
Local $WM_LBUTTONUP = 0x0202

Local $MK_RBUTTON = 0x0002
Local $WM_RBUTTONDOWN = 0x0204
Local $WM_RBUTTONUP = 0x0205

Local $WM_MOUSEMOVE = 0x0200

Local $i = 0
    Local $hWnd = WinWait("[CLASS:ThunderRT6FormDC]", "")
    Local $hControl = ControlGetHandle($hWnd, "TEST BY GUTBRUSH", "ThunderRT6PictureBoxDC5")

;Trying to do the same with sendmessage
_Sendmessage($hControl , $WM_LBUTTONDOWN ,1,19,14)
_Sendmessage($hControl , $WM_LBUTTONUP ,1,19,14)

;THIS WORKS FINE WITH CONTROLCLICK AND CONTROLSEND.
;ControlClick($hWnd, "TEST BY GUTBRUSH", "ThunderRT6PictureBoxDC5", "Left", 2, 19, 14)
;ControlSend($hWnd, "TEST BY GUTBRUSH", "ThunderRT6PictureBoxDC5", "U")
;I want to do that with _sendmessage, instead of controlclick and controlsend.
EndFunc

Still cant make a click with _sendmessage to 19,14 (x,y) of a control. im going to reach it hahaha

 

thanks, guybrush

_SendMessage ( $hWnd, $iMsg [, $wParam = 0 [, $lParam = 0 [, $iReturn = 0 [, $wParamType = "wparam" [, $lParamType = "lparam" [, $sReturnType = "lresult"]]]]]] )

Now you're sending wParam of 1, lParam of 19, and your return value is 14.

Usually, in .net, using 'l' to start a variable name is going to make it type Long, 'w' is Word. You need to convert your x and y coordinates into a long value. You can do that by using the _WinApi_MakeLong function.

I'd suggest working with some windows messages before you try sending them, so you can better understand what you're doing.

_WinApi_LoWord($iLong)  ; Returns the low word of a longword value
_WinApi_HiWord($iLong)  ; Returns the high word of a longword value
_WinAPI_MakeLong($iLo, $iHi)    ; Returns a long int value from two int values

These are functions you will encounter, and should have used, when working with windows messages.

Thanks, tell me if im right, the first number is the wparam and The number of clicks, ThE second number is The lparam and ThE x y cordinates that must be in long format, the lAST number is ThE return value that doesnt really matters.

So, if i convert the x y to long using that api should this code works? Do you see ay other errors?
