I need to do some clean up work before my MFC SDI program exits. How and where can I break into the program to do these things. I need to close a serial port in particular.

Thanks

Where is the handle of your COM port stored ? You can close the port in the destructor of the class that contains this handle for example.

Or you can override the ExitInstance from your CWinApp class and close it there.

Hope this helps

CPicture control

I have a few Property pages (not Wizard). On one of these I am displaying a picture (Picture Control). The file name is in a global variable. When I initialize it, the picture is displayed correctly. If a file is loaded, I want to show the picture when the user switches between the tabs. Currently when I come back to the tab with picture it is not displaying again. I have written the following code in OnSetActive event -

<br />
if (g_strFileName != "") {<br />
	CDC *dc;<br />
	dc = GetDC();<br />
	CPicture ppic;<br />
	ppic.Load(g_strFileName);<br />
	CRect rc;   GetDlgItem(IDC_RECT_BITMAP)->GetWindowRect(rc);<br />
	ScreenToClient(&rc);<br />
	ppic.Render(dc, rc);<br />
	ReleaseDC(dc);<br />
}<br />

I am also calling Invalidate(TRUE) in InitDialog. Any help would be appreciated.

I have also tried OnPaint/ InitDialog etc. No luck. Thanks.

1. Are you returning CPropertyPage::OnSetActive(); in from your OnSetActive() function?

I am also calling Invalidate(TRUE) in InitDialog. Any help would be appreciated.

--> InitDialog() function is only called once and not everytime you navigate through the tab pages. so it won;t help.

Thanks

Thanks Abhi for replying to my question Big Grin | :-D

. I somehow found a solution. I made the picture control Transparent and Simple and moved the painting code to OnPaint. Now it seems to be working perfectly fine. Still not sure what the problem was Confused | :confused:

I have a semi-transparent window. I need all mouse clicks to fall through to proper windows underneath mine. I need to implement a "click-through window"

How do I do this? Confused | :confused:

Handle WM_NCHITTEST and return HTTRANSPARENT.

HTTRANSPARENT is usefull when you create a control and you want clickthrough to the parent... However in my case I want clicks to fall through a top level window to the underlying windows.

Ah, right you are. Sorry, I never noticed that HTTRANSPARENT only forwards mouse messages to windows in the same thread.

Files Manipulation

Hi all:
I'm required to manipulate files order through a listctrl, in that case the file ordering appears after the execution of DOS command "dir" must be the order I've specified in that listctrl. But note it has nothing to do with the command "dir" itself, the ordering after the execution of "dir" has some meanings to me!

I already come up with a solution which is the first file copy to the certain folder is appearing at the top of the list after execute "dir".
But with little testing I found that this solution is unreliable within certain environments. Such as if the destination folder is not clean (has some existing files and folders).

How can I accomplish this with other solutions?
Can anybody provides other alternatives, really stable ones!

Thanks for viewing!

Only on NTFS volumes. With FATxx volumes, they are enumerated in the order in which they were added to the FAT. The default sort order provided by the Dir command supercedes this, however.

click into view of a website return the content of it

Hi and Happy New Year!

I want my app running in the background. If I press "SHIFT" + "left mouse button" my application should get the content of the website (not the HTML code oder pic, text only).

I work with keybd_event() to send keys .

keybd_event(VK_CONTROL, 0, 0, 0); // press control
keybd_event('A', 0, 0, 0); // press 'a' to mark all
keybd_event('C', 0, 0, 0); // press 'c' to copy
m_ctrl_OriginalText.SetFocus();
keybd_event('V', 0, 0, 0); // press 'v' to paste

But I have a problem: I don't know how to send the keybd_event() of my app to a website I see. If I click the website my app'll loose the focus and doesn't work.

How can I solve this problem? Confused | :confused:

Thank you for your interest!

I dont see why you are trying to use a weird workaround...

You can user COM to properly access every aspect of the web browser (assuming u are talking about internet explorer)

You will have to write extensions for all the browsers where you want to accomplish this. If its for Internet Explorer its called writing BHO's (Browser Helper Objects). Search msdn for 'BHO'/'Browser Helper Objects'.

Hi,

Can anybody suggest a way to completely overwrite the contents of a text file with some new text?

Thanks very much,
