Explain hwnd VBScript Code

Please explain the following vbscript code. Answer soon.

"Browser("index:=0").GetROProperty("hwnd")"
Hi, I'm working in QTP9.0. Please explain "hwnd" and its use in QTP script?

Hi Sunita,

'hwnd' is a property of an object, just like name/title.

"Browser("index:=0").GetROProperty("hwnd")"

This line of code will retrive the value of "hwnd" property for the Browser with index 0. (i.e. the first browser that was opened.)
Using this property you can then perform actions on that particular browser.

try to execute this code...
Open a notepad file before executing the code.

' Get the hwnd value for the notepad into a variable.
val_hwnd = Window("Notepad").GetROProperty("hwnd")
msgbox val_hwnd

' Perform action on the notepad whose hwnd value matches with the captured one.
SystemUtil.CloseProcessByHwnd (val_hwnd)

Hope this helps you understand.
Let me know if you still have any doubts.

Regards,
Tina Mahajan.

hi,

Thanks for giving me such a nice code,

I am using the following code for Minimize window:
hwnd1=Browser("Prod-CST1").GetROProperty("hwnd")
hwnd2=Browser("Prod-CST1").Object.HWND
Set cWindow=Window("hwnd:="&hwnd2)
cWindow.Minimize

and this code is for Restoring window
hwnd3=Browser("Advertiser: Ongoing").GetROProperty("hwnd")
hwnd4=Browser("Advertiser: Ongoing").Object.HWND
Set cWindow=Window("hwnd:="&hwnd4)
cWindow.Restore

I am using QTP 9.2 and IE 7.0 for record and run scripts
The above both code is working fine in Windows XP but This code is not working in Windows Vista,

Could anyone please help me for Vista.

Thanks,
Chetan
