Yes, I meant Keyboard Hooks, and at least in my own app, I'm sure I was processing ONLY WM_KEYDOWN.
Thank you masters!

I want to know how to determine if the user is connected to the Internet or not. But I have a limitation, that's I MUST use pure Win32/64 API only. any help?
Thank you masters!

Try InternetCheckConnection[^] from the WinInet API. InternetAttemptConnect[^] might also serve you.

Working with a USB is not like working with a serial port. You can't simply open the port and read/write data. Instead you have to get a handle from a device driver that is supplied with the device you want to communicate to.
So in brief, you never access the port directly but a driver and you never 'know' that you in fact access the USB port through the driver. You simply communicate with a driver. To get the handle, you have to use CreateFile and once you have the handle, you can write or read data using WriteFile/ReadFile. You can exchange driver specific information using DeviceIOControl.
All of these things are very specific to the driver (and device) you are accessing. So, if you want to information, you will need to be much more specific and tell us which device you want to access.

for example, an USB hard lock.

On Cedric's behalf:
You need to read his message again - look at the website for the supplier of the hard lock (whatever that is). Usb is NOT like the serial port, you talk via device drivers. So you need the information from the supplier of whatever the device is.

You are not compelled to use of MFC on your program.

Well you need to a handle to desktop window you can use of HWND m_hwndesktop= ::GetDesktopWindow(); and then you can use of your code.

I have a problem in reading numbers as "numbers" from a text file using getc...as it reads it as a character.
I am supposed to perform arithmetic operations on the numbers read from a text file.
The numbers are both of integer format and float format.
 
|
|
|
|
|
How are you reading the number?
In C you can use fscanf.
int x;
fscanf(fp, "%d", &x);
In C++ you can use fstream classes.
std::ifstream fp("filename");
int x;
fp >> x;

You can read your values with CString class and then use of CString::Foramt or itoa.

To move an item up, call GetNextItem(-1, LVNI_SELECTED) to get the index of the selected item. Call DeleteItem(nIndex). Call InsertItem(nIndex - 1) to insert the item back in the list control.

Hi,
I created an dialog application in SDK. Dialog does not contain any control. I tried to capture WM_KEYDOWN message, but not receiving this messaage. In MFC I can track this message in PreTranslateMessage but I do not know how to track in SDK. Any Idea please.
Thanks

BOOL CALLBACK DialogProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
BOOL bResult = FALSE;
switch(uMsg)
{
case WM_INITDIALOG:
// implemention code;
bResult = TRUE;
break;
case WM_KEYDOWN:
// implemention code;
bResult = TRUE;
break;
}
return(bResult);
}
DialogBox(g_hInstance, MAKEINTRESOURCE(IDD_DIALOG1), NULL, DialogProc);
