I am new to Windows programming and I am trying to click an item in listview control for that I need to take the rect size of the listview.Can anyone help me regarding ListView_GetItemRect macro.
I used like this:
ListView_GetItemRect(e3Obj.eHwnd,3,&rec,LVIR_BOUNDS);
But I am not getting any values in the RECT rect.Kindly help me
- What value does this macro return? TRUE or FALSE?
- Is the e3Obj.eHwnd a correct control handle?
- Does an item with indesx 3 exist?
Besides, please, use Code tags and white spaces within the parameter list:Code:BOOL bRet = ListView_GetItemRect(e3Obj.eHwnd, 3, &rec, LVIR_BOUNDS);
1.Macro returns false
2.Yes eHwnd is the correct Handle as I checked with LVM_GETITEMCOUNT.
3.Yes there are total 20 items
b=ListView_GetItemRect(eHwnd, 3, &rec, LVIR_BOUNDS);
Can you please give me a small example how to use &rec. Thanks in advance
It means that the call was unsuccessful.Quote:

The macro still returns FALSE.
1.Can you please let me know what would be the possible mistakes I would have done.
2.Is there any macro to click an item in listview or can you help/guide me regarding this.
1. There may be some reasons for ListView_GetItemRect to fail, like
- invalid window handle
- invalid item index
- perhaps, some others
2. What are you trying to achieve?
Sir I am developing an automation tool for which I need to click on the item in the listview. As there is no macro for directly clicking on listview item.One of my colleague suggested me, " to get the listview item size using ListView_GetItemRect and then try to convert it to X,Y mouse point and click on it".But I am completely blank. Please help me and sorry for disturbing you a lot sir.
Are you calling these LVM_GETITEMCOUNT, ListView_GetItemRect from the same process where list control is placed or in some other process?
I am calling in the same process.
Things I have done:
Sample code:
RECT rect;
int ix;
ix=ListView_GetItemCount(e3Obj.eHwnd);
//I am getting 20 in ix.Also I have checked it manually.
BOOL bRet = ListView_GetItemRect(e3Obj.eHwnd, 3, &rec, LVIR_BOUNDS);
Sir also let me know am I following the correct way to click on the item in listview or is there some other way.
Again: is it the same process that does contain this list control or is it some other process?Quote:

No, I didn't.Quote:

Only SOME windows message calls will work when used on controls that have been created in another program/process.
Should I say it that I already warned you in the other thread? ;)
Your problem is not the macro. Your problem is that you hardly understand how Windows controls work. You're looking for some magic macro while there is no one in your specific case.Quote:

It may be solved two different ways. First is code injection. This (writing code to remote process and creating remote thread) or that (injecting dll) way your code have to appear in the context of the process you to automate. Then by means of some IPC (inter-process communication) your code gets the command 'click on item 3', gets the corresponding item rect (by means of the macro, or sending LVM_GETITEMRECT, whatever), positions mouse cursor inside the rect, emulates left button down and button up events. I repeat: All this code is inside the victim process.
Second way implies no code injection, but ability to read/write the victim process memory is mandatory anyway. The automation process allocates remote memory enough to fit RECT in and passes the remote address to the macro, then it reads the rect coordinates and emulates the mouse button click as explained above. And does not forget to deallocate later, of course.
This is how it looks from "helicopter view". A special headache is acquiring rights enough to read/write remote process memory or inject dll, as since Vista times Microsoft decided to make this kind of tricks be much more tricky than it was before.
Now can anybody explain me how this could be done by somebody who's completely blank and new to Windows programming? Guys, if you really need some automation engine, you'd better go with already proved solutions like AutoIt
Dear Igor, Thanks for your advise/warning/solution .Surely It will help me a lot.
Thanks for your reply,now I understood my issue.
I would suggest checking if the item is visible

because if its not, you cannot get the rectangle. You can also make it visible
