How do find properties of controls of other applications?

For example: Looking to find the properties (ID,Value,Text, Enabled, etc...) of a text box on Internet Explorer.

We found APIs to find the handle, coordindates, caption, class.

How DID you find the handle and control type?

You must send windowmessages to the control to get at the properties. I'm not quite sure how it works either, but I need to know how to find the handle & control type.

The GetWindowLong function will get the styles and extended styles.

a& = SendMessage(iCheck&, BM_GETCHECK, 0&, 0&)
would return the state of a checkbox, given the handle of it (iCheck). A lot of controls have similar constants. confusingly, list boxes and combo boxes have different constants.

Here it is

Private Const EM_SETPASSWORDCHAR = &HCC

Here is the full code.

Code:

Private Const EM_SETPASSWORDCHAR = &HCC
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

'Usage
SendMessage EditHwnd, EM_SETPASSWORDCHAR, byVal "*", 0

Hi!
Would you please tell me a site or URL that contains the constant values? for example the value for BM_GETCHECK (that i need it but i cant find!!)

The specific constant is :

VB Code:

Const BM_GETCHECK As Long = &HF0&

You can use the API Viewer to find the constants : http://www.activevb.de/rubriken/apiv...viewereng.html
