Hi,
I'm preparing a device driver for signature & submission.
ChckINF gives an error E22.1.1310 ("Class measurement {...guid..}} is not recognized") (not exact wording)
(Basically we're declaring a custom class for the device, as it doesn#t fit any of the predefined ones)
Is this an "acceptable failure"? I can't find any information on this one.
Also, on one test system, ChkINF complains about incompatibilities in other INF files. What about that?

As far as I know when you leave the path of the (MS) standard you are on your own. Declaring a custom class is way off the path.
Also, with your custom class you can NOT pass the tests for signing (which answers your other question).
Rules may have changed, but this is what I know from about a year ago.

But MS defines only classes for devices that DO NOT need a separate driver??
[edit] just (really!) found the following:
"Under Windows XP, vendors supplying their own USB client driver should make that driver a member of the USB setup class in the INF Version Section of the driver's INF file."
However, no mention for what to do on Non-XP systems

I need to perform the same function that selecting a view under the "Windows" menu does. I have succeeded with minimal results. Does anybody have any suggestions?
Thanks in advance.

CFrameWnd::MDIActivate activates a given MDI child. To enumerate all MDI child windows (which you probably need to dynamically construct the View menu), use EnumChildWindows with CMainFrame::m_hWndMDIClient (not directly with the frame window).

how do you show a file in the machines default text viewer ??
i wont always know that notepad.exe is on the box, so i would rather open for default text viewer associated by o/s than to use a system command to open my file in a static program....
any suggestions ?? thanks in advance.

Just ShellExecute (or whatever you use to start an app) on the text file itself, and the shell will automatically run the correct viewing app

Use ShellExecute() API.
For example:
ShellExecute(::GetDesktopWindow(), NULL, "c:\\myfile.txt", NULL, NULL, SW_SHOWNORMAL);

I have a program which is using Winsock and I would like to put the local IP Address on the title bar of the dialog. Unfortunately all I get for an IP address is 0 and in dotted quad 0.0.0.0
here is some of my code:
<br />
Sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);<br />
...<br />
<br />
sa.sin_family = AF_INET;<br />
sa.sin_addr.S_un.S_addr = INADDR_ANY;<br />
sa.sin_port = htons(2000);<br />
<br />
iError = bind(Sock, (LPSOCKADDR) &sa, sizeof(struct sockaddr));<br />
<br />
SetWindowText(hDlg, inet_ntoa(sa.sin_addr));<br />
I noticed in MSDN that by using getsockname that the IP address might not be available always especially if I/O has not occured. But I thought that when I bind the socket that the sockaddr_in structure gets filled in and that one of the variables should contain the address which it is connected with. What am I missing here?

 I have to develop an application in which hardcopies via keystroke are disabled. The keystrokes I know are: ALT+Print, CTRL+Print, SHIFT+Print and Print alone. How can I disable these keys in VC++ ?
Thanks ...

I'd recommend using a hook. Install it by use of SetWindowHookEx of type WH_KEYBOARD and react on your requested keys inside the provided hook function.
|
|
|
|
|
Do you have a reference for SetWindowHookEx or better an example ? Thanks, Olaf Rodewald
|

In case you need a system wide hook, you need to implement the hook function inside a DLL. The function could look sth. like this:
__declspec(dllexport) LRESULT CALLBACK HookFunction(<br />
int code,<br />
WPARAM wParam,<br />
LPARAM lParam)<br />
{<br />
char szVCode[50];<br />
<br />
sprintf(szVCode, "Virtual Key code: %lx", wParam);<br />
MessageBox(NULL, szVCode,"Key stroke", MB_OK);<br />
}
Installing it in your application is done by calling SetWindowsHookEx:
hHookDll = LoadLibrary("hook");<br />
hHookProc = (HOOKPROC) GetProcAddress(hHookDll, "HookFunction");<br />
<br />
hSystemHook = SetWindowsHookEx(WH_KEYBOARD,hHookProc,hHookDll,0);
Finally, don't forget to unload DLL and unset the hook:
UnhookWindowsHookEx(hSystemHook);<br />
FreeLibrary(hHookDll);
If you need some more detailed information, have a look at MSDN - there's lots of stuff about that topic.

you have to put your system wide keyboard hook in a .dll
http://www.codeguru.com/system/KBHook.html
that has a good example of a system wide keyboard hook , and an application example that uses the dll.
i was able to build my own keyboard hook after going thru that , and ive used it w/ no major problems. note there is a bug in the code there. u need to get rid of hook = NULL; line from dllmain;
hope this helps

Hello,
I have a problem: I have two separate applications:
1) an ATL explorer shell extension
2) a MFC application which should display the files
Because of project reasons the files have to be different, the
explorer shell extension must be a DLL and the display application
must be a MFC project as EXE.
How can I pass the selected files from the DLL to the EXE?
I first thought of GlobalAlloc but MSDN says that this function
is only provided for 16-bit support.
What would you suggest? Is there a way to share an array? It is a bit difficult to implement an IPC system in this case...
Thanks
-Dominik

I'd say GlobalAlloc is just fine. IMHO the docs are a little misleading with respect to the applicability of this function (the proposed alternative, HeapAlloc and company, doesn't add much to this for your particular needs).

Hi, everyone!
Where is the the precompiler directive __PTHREADS__ defined?
Defined in compiler? What is the meaning and function of
the precompiler directive __PTHREADS__?
Thanks in advance,
George
|
|
|
|
|
pthreads is a unix threading library, and I can only imagine the application you are trying to compile makes use of the Win32 version of this. __PTHREADS__ will be found wherever the pthread include files are, thats about all that can be said.
|
|
|
|
|
Thanks!
I have another, does Windows use pthreads library?
If I am using Windows version of the project, can
I passby the codes has something to do with pthreads?
Cheers,
Geroge
