Hello,
I'm trying to create a PopUpMenu, I'm not sure that's the real name. I mean the window that appears when u right click at this site for example. I want to have such a thing, which API should I use?
And I want to create 2 seperates things, one when u right click in the ListView, and one when u click at another ListView.
Thanks,
NM
First you need the menu resource. Then you'll want to handle the WM_CONTEXTMENU message in your message loop. From there, it depends on your framework. Are you using MFC, some other framework, or straight WinAPI?
Also have a look at TrackPopupMenu(Ex) and other menu functions in MSDN.
There is an MFC example of Context menu but you could very easy to adopt it to the plain Win32 type.
I code in pure api, what kind of resource do you mean? I dont use a .rc file to create my window.Quote:

I can only find some things about recourse file with it, none in pure code.
Then you must use Menu APIs to create context menu.
I came up with this
Code:case WM_CREATE:
hmenu = CreatePopupMenu();
memset(&emii, 0, sizeof(MENUITEMINFO));
emii.cbSize = sizeof(MENUITEMINFO);
emii.fMask = MIIM_STRING | MIIM_FTYPE;
emii.fType = MIIM_STRING;
emii.dwTypeData = TEXT("Copy");
emii.cch = 4;
InsertMenuItem(hmenu, 0, TRUE, (LPCMENUITEMINFO) &emii);
if i use GetLasterror at the second code, error 1401:Invalid menu handle.Code:if(wParam == IDC_BLOCK)
{
TrackPopupMenu(hmenu,TPM_LEFTBUTTON,100,100,0,hWnd,0);
x = GetLastError();
Where is hmenu declared? It is going to have to be global if you assign it in WM_CREATE then use it later in a different message handler.
And where does your second code block come from? And what is IDC_BLOCK? :confused:
Note that you should NOT call GetLastError unless an API called just before has failed.
hemnu is declared in my wndproc (main window loop), so that shoudl be fine.
IDC_BLOCK is name of a button of mine, so if its clicked, it should show me the popupmenu.
It should not work at a button alter, but this was for test prupose.
Sorry, but we cannot believe...Quote:

thanks that worked, which i define as weird, but well it works:)
Next problem is that when i add 2 lines, they are next each other, and not under each other, it looks weird, and how can i make it that if people right clcik at a treeview, the window appears and that when they hit ignore, the value of the third colum in a char gets?
Weird was your declaring it in function scope. Right after processing WM_CREATE the function returns, and your menu handle gets lost. Next time when you process button click you use uninitialized variable value and fail with no doubt.Quote:

I see, thanks for all the help, but
How can i make it like that, when someone right click at a listview box, the window appears, and when they click at something the char from that colum gets in a char.
Grz
NM
To handle a "right click" you should handle WM_CONTEXTMENU message (note that hoxsiew already pointed it out in the post#2!)
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?
Please, explain more clear and with normal words rather than abbreviations what you want and what for.
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.
Could you explain me that a bit more? Its not really clear for me
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:
http://msdn.microsoft.com/en-us/libr...83(VS.85).aspx
Tahts my new ProcCode:LRESULT CALLBACK ListViewProc(HWND hWnd, UINT uMsg, WPARAM wParam,
LPARAM lParam, UINT_PTR uIdSubclass, DWORD_PTR dwRefData)
{
MENUITEMINFO emii;
switch (uMsg)
{
case WM_CREATE:
hmenu = CreatePopupMenu();
memset(&emii, 0, sizeof(MENUITEMINFO));
emii.cbSize = sizeof(MENUITEMINFO);
emii.fMask = MIIM_STRING | MIIM_FTYPE|MIIM_ID;
//emii.fType = MIIM_STRING;
emii.dwTypeData = TEXT("Block");
emii.cch = 3;
emii.wID = 1;
InsertMenuItem(hmenu, 0, TRUE, (LPCMENUITEMINFO) &emii);
memset(&emii, 0, sizeof(MENUITEMINFO));
emii.cbSize = sizeof(MENUITEMINFO);
emii.fMask = MIIM_STRING | MIIM_FTYPE;
//emii.fType = MIIM_STRING;
emii.dwTypeData = TEXT("Ignore");

1. Where did you set a break point?
2.This line in read does not make any sense, because WM_RBUTTONDOWN is defined as a number not equaled to zero.Quote:

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)
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.
What "worked"? You've just written it didn't! :confused:Quote:

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?
Have a look at LVM_HITTEST Message and LVM_SUBITEMHITTEST Message
Thanks all i got it working now
