The listview is in another process, I get the listview handle by FindWindow and enumerate child window.
I want to get PyClistView object because it has convenient functions like 'GetColumn', 'GetItem'.
Then probably you need GUI automation tool like pywinauto. Working with ListView controls in another process is already simplified here. And it's Python as well.

I have a simple tkinter.messagebox.showinfo inside a python code, how can I close the messagebox inside the python code as the code runs?
Thx.
This is not possible as far as I know because the tkinter.messagebox.showinfo waits for user input, which is to click the button. This is what showinfo is supposed to do.
If you want to display something to the user and make it disappear after a while (say a loading... sign) I would suggest using a progrssbar instead of a messagebox.
In any case, you will need another thread to control the functionality of your current thread.
This post may give you more info about using threads this way.
Also note that it's recommended that secondary threads are not given access to tkinter objects.
I am new to MFC. In the project I am working on the dialogs are created in resource file(.rc).
In that there are OK button(id ID_OK) and Help button (id ID_Help). I am not able to find the event handlers for these two buttons. There are other buttons where the event handlers mapped are easily found. If someone teach me how to find those event handlers it would be very helpful.
And how can I find the functions which get called on clicking of the particular button by debugging in visual studio?
Thank you.
Double click the button (shown in rc) opened in Resource View in Visual Studio and you will be automatically placed by Studio where the Event handler is located in your code.
If this does not work, then probably delete the Button with ID's ID_OK and ID_Help in your resource view and again add it to the resource using different ID and then try to generate the event handler by double-clicking those buttons in resource view. This is because sometimes the value of ID's conflict with other ID values and hence Studio is not able to generate the Event-handler for you in that case.
Buttons don't have direct event handlers as in other frameworks (like in C#, WinForms etc). You must use message-maps in MFC.
ID_OK maps to virtual function CDialog::OnOK, you can just write your virtual function implementation. Framework will call it for you. You can also handle this message with WM_COMMAND message entry.
There is no standard resource ID as ID_Help - it is always capital, and has to be always in caps! No one is stopping you from using small letters, though - it for consistency and better readability.
Instead of fiddling with resource files (.RC and resource.h), mapping the same with your dialog class and things like that. I suggest you to go, and learn, without resource file. Start with drawing in frame (circles, filled-triangles whatever). Learn and know why virtual function are there for some messages, and message-maps for other (most) messages.
My two cents.
How can I add control(like ListCtrl and CButtons) on CFrameWnd?
Thanks
Your best bet would probably be to create a CDialogBar and stick your controls on that.
CListCtrl is the same as CListView. You can also create button by calling directly button’s Create member or calling Create API passing BUTTON as the name of the class.
If you want to use many controls like in a dialog why not to use CFormView derived class as your view?
I want to add a simple panel to a dialog created using Visual Studio resource editor, but the resource editor doesn't allow this - I need to add my own CWnd as a dialog child. However that way I think I have to use CWnd::Create manually, and pass in names for the class and the window.
I want to create an ID like IDC_MYPANEL, and as much as possible add the window so it works like something defined in the template. What's the right way to do this, and what's the best MFC class to use as a simple panel... just use CWnd itself?
What do you mean by 'a simple panel'? If it's a custom control, derive from CWnd, override Create() and call CWnd::Create() with NULL as the class name so that MFC makes its own, and add a line to resource.h with the IDC_XXX value of your control. If it's a sub-dialog, with controls on it, derive from CDialog and call CDialog::Create() with the IDD that you define in your dialog.
The only difference when creating a control at runtime is that in OnInitDialog, you do some Create() and initialisation things, and you don't include a DDX_Control() line for that control. For the rest everything works the same.
How can I obtain the Window Rect of a CDialog which is based on a dialog template. The dialog is not and can not be visible
It might be tricky with CDialog, because if you dont show the CDialog, the window handle is not created and you cant call GetClientRect.
Might i suggest calling CreateDialogIndirect instead to create the dialog, then you can get the client rect. You dont need to show the dialog. I think as long as the window handle is created, the GetClientRect should work. I am not an expert though and its been many years since i have written MFC code.
Well...
In Windows API-land, you could load the resource yourself (FindResourceEx, LoadResource), understand the binary structure of the dialog template resource (some clues at http://blogs.msdn.com/oldnewthing/archive/2004/06/22/162360.aspx), convert the size of the dialog in the dialog template from dialog units to pixels (check out http://msdn.microsoft.com/en-us/library/ms645475(VS.85).aspx).
I'd be curious why you'd want to do this, though.
