Yeah this works...

HWND hprg = ::FindWindow(_T("Progman"), NULL);
::SendMessage(hprg, WM_CLOSE, 0,0);

You can use spy++ to find that out.

C++ class hierarchy tool

Hi,

Does anyone know of a C++ class hierarchy tool? I need to document and analyze the structure of a large application.

Thanks,
Royce

Cannot size window using STARTUPINFO

I would like my newly window to open up with the given sizes. The following code maximizes the window when it gets created. Why doesn't it work? Thanks!

STARTUPINFO stStartUpInfo;
PROCESS_INFORMATION pProcessInfo;

memset(&stStartUpInfo, 0, sizeof(STARTUPINFO));
stStartUpInfo.cb = sizeof(STARTUPINFO);
stStartUpInfo.dwFlags = STARTF_USESIZE;

CreateProcess(NULL, CmdLine, NULL, NULL, FALSE, NORMAL_PRIORITY_CLASS,
NULL, NULL, &stStartUpInfo, &pProcessInfo);

Look like the following is missing:
stStartUpInfo.wShowWindow = SW_MAXIMIZE;

Your code looks like it would show the window hidden as it memsets the struct to zero and 0 is SW_HIDE.

The window does show up but it's maximized. That's not what I want. I want the window size to be set to what I defined for dwXSize and dwYSize .

Re: Cannot size window using STARTUPINFO

Stephen Hewitt1-Feb-06 14:14

Try this:

STARTUPINFO si;
ZeroMemory(&si, sizeof(si));
si.cb sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW | STARTF_USEPOSITION | STARTF_USESIZE;
si.wShowWindow = SW_SHOWNORMAL;
si.dwX = 0;
si.dwY = 0;
si.dwXSize = 100;
si.dwYSize = 100;

It still maximizes the window. Ryan (below) mentioned that application can ignore the STARTUPINFO struct if it wants to. So is there no way around this?

Re: Cannot size window using STARTUPINFO

Before I started to look for ways around it I would verify the code with notepad (an application that respects it, I think) or something. I can't think of any easy way around it. You could install a WM_CBT hook with the SetWindowsHookEx API but this would involve setting a global hook (and thus creating a DLL and taking care that it doesn't crash or effect other applications).

An application is free to ignore the values in the STARTUPINFO structure if it wants to.

How to span columns in CListCtrl

Eric Jacobsen1-Feb-06 10:10

My application scrolls data in real-time over several columns using a CListCtrl (MSVC++ 6.0). I'd like to occasionally put a user-message that takes up the entire row, spanning all the columns in the table. The MFC Grid Control doesn't seem to have this feature (hint hint).

Does anyone know if this has been done? Thanks!

Which implies that a list control certainly doesn't!

Can you embed an Excel sheet into the application?

Yes, the Excel functionality is just what I'm thinking of, but I think embedding an Excel sheet would probably be overkill

You could subclass the control and put code in to draw to text manually (just the "full line" text).

It's not supported by the control directly, but it isn't terribly difficult.
Review the various custom draw articles in the CListCtrl section here on CP - you want to intercept drawing for a specific row, and draw it yourself.

This is what I'm looking into now. I'm stumbling a little on the issue of how to derive from CListView because CListView HAS A CListCtrl, but supposedly can act as if it IS A CListCtrl. Thanks for the response...

Re: How to span columns in CListCtrl

Ryan Binns1-Feb-06 17:47

Actually, CListView IS a CListCtrl. If you look at the implementation of GetListCtrl(), it merely does

return (*(CListCtrl*)this);

or something similar.
