I have need to open a socket to grab packets from an outside server. I have many questions about this undertaking.
The socket needs to transfer data back and forth between the client and the server.
* Is there an easy framework for this in MFC?
* Static vs. Dynamic port requests.... Should we use the same port each time we run the application? Or should we use dynamic ports?
* If we use dynamic, does that mean the Windows firewall will pop up a message saying "Hey, please verify that you want this app to access the internet?
* If we use static ports, how can we gaurantee that no other app is using the same port when we request it the first time.
* If we use static ports, how do we prevent other applications from stealing our assigned port?
* Do developers usually go to the firewall makers and try to get their applications pre-approved?
* Is there a way to be 'pre-approved' for most firewalls?
Spyware Questions (we certainly aren't spyware, we just want to make sure we're not labeled as such):
* Are there any certification programs you can go through to verify your app is not spying?
* Are these effective in terms of convincing users you're a good person?
* Same kinda question as above, is there a way to get pre approved for spyware companies and let them know who you are so they won't label you as such.
* Any other hints in terms of not being labeled this app-killing adjective?
Thanks very much in advance!

Hi
I have set a Background image for my ActiveX ( ATL Composite Control) and it has some static text boxes. To make them transparent i did the painting of the static text controls ( in WM_PAINT). I.e after setting the image in OnEraseBkGnd(), i invalidated the static controls whose WM_PAINT is handled. This will TextOut the text above the BG image. But when i put this in web page, it seems that the OnEraseBkGnd() is calling frequently and thus the static control paint everytime, creating flickering of the static controls ( controls blink's).
Also when i call SetWindowText() to set new string in static control, I have to call Inavlidate() the whole control to make the new text display correctly. If i just call invalidate of static control, it overwrite the old text. Next painting of the window will solve this!!
How to solve these issues?
i have used this CP link to set background.

There is a OnCtlColor Member of CWnd, in which you can set the backmode to transparent.

I did try with WM_CTLCOLORSTATIC, i could change the bgmode & color
Not able to make it transparent. I did have to draw using WM_PAINT
M_CTLCOLOR is not fired,I think it is due to ATL non MFC

IIUC you packaged the control into a CAB and are installing it via the <object> tag? When you release a new version, update the version numbers in the DLL's version resource, and update the version numbers in the INF file (packaged inside the CAB) to match. Then on the web page, update the version field in the codebase attribute to match. IE will do the rest.

Hey everyone:
I want the user to choose when they close down my application, so I listen for user input... but these pesky IM windows always interrupt my app and steal focus. I've tried not responding to the following messages.... then I tried what you'll see below.
I thought by handling them I'd be OK... but IM windows (from Gaim for instance) totally kills focus of my program. Thoughts? Thanks!
case WM_KILLFOCUS:
case WM_QUIT:
case WM_CLOSE:
case WM_DESTROY:
return(DefWindowProc(hWnd, message, wParam, lParam));

You can't prevent your window from losing focus to something else. Imagine if two programs did this - they would constantly be fighting over which one is the active window. What is it about your app that makes you want to prevent other windows from being active?

I can imagine the problem you describe. However I've seen some applications deal with it, and not yield control. I'm building a simple screensaver which I think shouldn't be interrupted by such trivial things as IM windows. You still hear the noise afterall.
So I *know* there is a way, because I've seen programs that don't change focus when another window requests it.
So how do you do it? :P

Well, a screen saver is a special case (in NT at least). The screen saver runs on its own desktop, so it will be the only window visible no matter what, because the interactive desktop won't be visible.

hi,
steps to capture the filename from the first dialog (CreateDlg)
1) store the Filename in the CString Variable before the Ok Button was Pressed.
2) In OnInitDialog of the Second Dialog i mean (UpdateDlg) create a an Object of the First Dialog (CreateDialog) :
//==============================================================
(ie) CreateDialog *mpmain = (CreateDialog *)GetParent();
CString str = mpmain->filenamemembervarialbe;
ComboBox.Addstring(str); //Adding to ComboBox in SecondDialog
//==============================================================
over, Good Luck.
uday.

----
I want to know what is *mpmain ??? is this MainDialog window ???

hi,
yes it is Main Window Dialog you are correct. also when you want to access the Mainwindow Dialog in second dialog dont forget to include the first dialog header in second dialog.
ie (i mean) # include "firstDialog.h" in the second Dialog.
good luck.
uday.
