Hi,

You can make use of _splitpath() after getting the complete path to the file.

how can I write a code for scanning harmful USB devices in a good programming language and with a good GUI.I have a database for the viruses
so when the USB device is connected the software will look up for in the list and if there is a virus tehn it will prompt the user.

Scanning USB devices is easy enough. How would your code know whether they were harmful?

convert CString to double

soongez5-Oct-09 4:46

Hey, I know this has been asked many times, and I've researched several solutions like atod etc,

here are some bits from my code.

CString line;
chkfile.ReadString(line)
CString token;
token = line.Tokenize(_T(" "),v);
TRACE(L"token %s\n",token);
TRACE(L"converted %d\n",_tstof(token));

chkfile is a CStdioFile.

the TRACE reads something like

token 66
converted 0

Why is always returning error code 0?

Thanks

%d expects an integer type
_tstof returns a double

Try with %f or %g or somesuch instead of %d.

Wait, so you already have your double in a string but you first want to convert to a float and then back to a string... Why don't use the string directly ?

Thanks the %f worked, but I used _tstof because the other double converters would give me errors such as cannot convert CString to char* because 'line' was a CString and I couldn't change it to char* when using ReadLine. I'm still pretty poor in using pointers etc.

The TRACE is just to test if the output is correct, it will be used somewhere else later in the program.

cheers.

Hi
Can Context menu be system modal, so that if any tool tip appears,it should display behind my context menu not above it...

Thanks

1/ I doubt it.
2/ How long is this menu appearing for? Yikes...
3/ If there was an answer, how long before your competitor says "Can I make my tooltip system modal, so no menu appears on top of it?"

Point 2 is the main one - a menu is a temporary thing.

If you *really* want to do your thing, make a window with lines of text that disappears when you click on one. You don't have to actually use the menu functionality of windows. It will be more work, but tough. You want something way aways from the norm, you have to do it manually.

Because str is a pointer and with sizeof(str), you're NOT finding the length of the string that str is pointing to.

If you need the length of the string, use strlen (or yet better use TCHAR and _tcslen)

It is a crappy thing, but it's life -^ Carlo Pallini

Aside of what Rajesh R Subramanian suggested you can also try:

const char str[] = {"C:\\Documents and Settings\\Test\\TestData"};
int i = sizeof(str); //Note that this will also include the terminating NULL character
