VC Programming controls other applications

The ukey Production Line of the factory requires serial numbers. The serial numbers on the housing are marked by the laser marking machine. Because the serial numbers and the marking are different, the internal serial numbers of the ukey are inconsistent with those of the shell, two people are required to work,

If the marking machine numbers the ukey at the same time, the above problems are solved. Because the Laser Marking Machine Software has no interface, and the manufacturer's support cannot keep up, I thought of writing VC software to control the marking software. The procedure is as follows:

1. Download spy ++ online first;

2. Find the main window: hwnd =: findwindow (null, m_strtitle); // m_strtitle is the title of the window.

3. Find the subwindow hwnd hwnd1 =: find1_wex (hwnd, null, "afxcontrolbar42", "");

In spy ++, locate the class and title of the required subwindow.

4. Find multiple child windows of the same type (in a parent window, there are multiple child windows without window titles, and 3rd child windows are required)

Hwnd hwnd5 =: find1_wex (hwnd4, null, "#32770", ""); // The first subwindow

Hwnd hwnd6 =: find1_wex (hwnd4, hwnd5, "#32770", ""); // The second subwindow

Hwnd hwnd7 =: find1_wex (hwnd4, hwnd6, "#32770", ""); // The third subwindow

5. Find the edit box: hwnd hedit =: getdlgitem (hwnd7, 0x65c); // 0x65c is the ID of this control in spy ++.

6. Set focus:

: Sendmessage (hwnd, wm_setfocus, null, null );
: Sendmessage (hedit, wm_setfocus, null, null );
7. assign a value to the edit box

: Sendmessage (hedit, wm_settext, (wparam) 255, (lparam) sztext); sleep (100 );

8. Send "Click message" to the button

: Sendmessage (hwndbtn, bm_click, null, null); sleep (100 );
: Sendmessage (hwndbtn2, bm_click, null, null );

 

Example:

Void ctestdlg: onok ()
{
// Todo: add extra validation here
Char sztext [256];
// Hwnd =: findwindow (null, "Han's laser marking software 5.3.3-[SKP]");
// If (hwnd): MessageBox (null, "find", "TJ", 0 );
Hwnd =: findwindow (null, "Calculator"); // m_strtitle = "Calculator", which is different in different languages

/* Hwnd hedit1 =: getdlgitem (hwnd, 0x193 );
: Sendmessage (hedit1, wm_char, '1', 0 );
Sleep (500 );
: Sendmessage (hedit1, wm_char, '2', 0 );
Return;
*/
Hwnd hedit1 =: getdlgitem (hwnd, 125); // the ID of Button 1, which can be observed in spy ++.
Hwnd heditmul =: getdlgitem (hwnd, 0x5b); // the ID of the multiplication number, which can be observed in spy ++.
Hwnd hediteq =: getdlgitem (hwnd, 0x70); // ID of the equal sign, which can be observed in spy ++.
: Sendmessage (hedit1, bm_click, null, null); sleep (500 );
: Sendmessage (hedit1, bm_click, null, null); sleep (500 );
: Sendmessage (hedit1, bm_click, null, null); sleep (500 );
: Sendmessage (heditmul, bm_click, null, null); sleep (500 );
: Sendmessage (hedit1, bm_click, null, null); sleep (500 );
: Sendmessage (hedit1, bm_click, null, null); sleep (500 );
: Sendmessage (hedit1, bm_click, null, null); sleep (1000 );
: Sendmessage (hediteq, bm_click, null, null); sleep (500 );
Hwnd hedit =: getdlgitem (hwnd, 0x193 );
:: Sendmessage (hedit, wm_gettext, (wparam) 256, (lparam) sztext );
Strcpy (sztext, "12345678 ");
: Sendmessage (hedit, wm_settext, (wparam) 256, (lparam) sztext );
: MessageBox (null, sztext, "TJ", 0 );
}
