C++ PopUpMenu

[VictorN]

To handle a "right click" you should handle WM_CONTEXTMENU message (note that hoxsiew already pointed it out in the post#2!)

[NLscotty]

thanks, i didnt release me that yet... sorry

That's working now, but its at the compelte GUI, i want it specific at the listview, and after that they can choose between Ignore/Block, i can see those, i've to give them the wIDD, but how can i handle those, and how can I get the line and the right colums variab out the lisvtiew?

[VictorN]

Please, explain more clear and with normal words rather than abbreviations what you want and what for.

[NLscotty]

Sorry, I would try to make it clearder:

First: The Pop Up Menu works now, that fine. But it works at the entire gui, I would like it to only work at the specific list View, so i should try to get the HWND from where the click is, thats question 1.

Second, when question 1 is working, Someone can go to listview -> right click -> copy, or w/e, so i need the value from the colum and right line of the listview, how can i do that?

Thanks.

You'll probably want to subclass your listview's wndproc and handle the WM_CONTEXTMENU in it's message loop instead. the listview has messages and notifications more appropriate for what you are trying to do.

[NLscotty]

Could you explain me that a bit more? Its not really clear for me

[VictorN]

Implement your own window procedure for this list control and handle WM_CONTEXTMENU message in this procedure.
It is just the same way like you've implemented the WndProc for your main window.

See this article from MSDN too:

Tahts my new Proc

In the last line i call it, but it doesnt work, i set a breakpoint at the ListViewProc, never gets there.

[VictorN]

1. Where did you set a break point?

2.

		case WM_CONTEXTMENU:
			if(WM_RBUTTONDOWN)			{
				
				POINT p;
				GetCursorPos(&p);
				 TrackPopupMenu(hmenu,TPM_LEFTBUTTON,p.x,p.y,0,hWnd,0);
			}

This line in read does not make any sense, because WM_RBUTTONDOWN is defined as a number not equaled to zero.
Besides, you don't need to call GetCursorPos: LPARAM already contains coordinates you need. Please, read MSDN about WM_CONTEXTMENU message.

3. You can also handle WM_CONTEXTMENU message in the main window procedure and check the WPARAM which contains the window handle of the child control (again, read the MSDN documentation)

[NLscotty]

1. In my new listview proc, it doesnt cross it.

2. Hmm, it worked, now you say it doesnt make sense, this confuses me a little

3. Oee but i was told this was how i should do it, to obtain the char value of the colum that is clicked.

[VictorN]

What "worked"? You've just written it didn't!

3. Oee but i was told this was how i should do it, to obtain the char value of the colum that is clicked.

Could you more clear define what "the char value of the colum that is clicked" means?

[NLscotty]

Could you more clear define what "the char value of the colum that is clicked" means?

Well, I posted before that it worked for the entire GUI, with that peice of coded, but now i want to to be specific to the ListView. So it works only there

Well, you can double click a listview and the value will be bleu ligned, right? Well every line of me has about 4 values, im only intrested in the third colum value. If some1 clicks at a line in my listview, and right click, this pop up menu should appears, with a choose, block/ignore, and if he clicks ignore, it should copy the value of the listview's third colum into a char ( or wchar_t, which i use). I dont know how I could explain it better, i could show a pic if you would like to?

[VictorN]

Have a look at LVM_HITTEST Message and LVM_SUBITEMHITTEST Message

[NLscotty]

Thanks all i got it working now
