I've created a MFC app with the Appwizzard.
The main view is a child of CFormView.
In the associated dialog i've created a listbox, and created the control variable for it.
the app's name is "hilos"
In hilosView.cpp i include a class called "hilos.h" as i need to create an object of that class and use it's member functions.
In "hilos.cpp" i need to be able to write in the listbox, but as in hilosView.cpp i include the header of that file, i can't include in hilos.h the file hilosView.h to see the listbox.
the listbox's control variable name is m_list, and it's a member of the (CHilosView : public CFormView) class. I can't declare an extern in hilos.cpp to be able to use it.
what could i do?
thanks!

do a forward declaration...
e.g. in the header file
class CHilos;
class CHilosView : public CFormView
{
// etc
};
and then put the include in the cpp file.
Hope this helps,
Andy

Hey,
I am using the "Printing without the Document/View Framework" tutorial, and I was wondering if anyone knows how to print text from edit and combo boxes in a nice grid type layout.
Thanks for the help

I have been working with the same VC++ project, modifying as I needed.
Now when I try to used one of the dialogs, I get an unsupported operation error.
The log file tells me that the dialog I was trying to use is not registered CDdialog_put_text
I am not a programmer - just someone that has to modify existing projects occasionally.
If anyone can help, it would be greatly appreciated

Hi,
I have installed the iTunes application on my PC and it has the Aquablue (Mac) look & feel.
I would like to know how I can create a windows application that has the same look&feel. Can anyone point me in the right direction?
Thanks!

See this[^] article. SkinMagic[^] is a commercial product that may be worth investigating. (I haven't used it).

Just ownerdraw everything yourself. (Seriously.)

That's what I thought...but I was hoping for a simpler (miracle) way to do it.
Thanks!

One simpler way could be to find someone else to do it for you.

Hi guys,
in my software I need to measure time duration between two hardware signals (which come via RS232 connection). And I'd need that with accuracy to millisecond. I'm wondering what's a reasonably good way (meaning good accurate results) to go about it? I'm now only thinking of using SetTimer() and KillTimer() with a counter variable to count the time, would that be able to provide a good accuracy?
Thanks

QueryPerformanceCounter does a good job.
Take a look at this article.

One way would be to use either the _ftime() or _ftime64() function.
e.g.
__int64 getCurrentMilliTime()
{
__timeb64 time;
_ftime64(&time);
__int64 seconds = (__int64)time.time;
return (seconds * 1000) + time.millitm;
}
_ftime()/_ftime64()

On NT/W2K/XP, you can use GetTickCount()

I'll have to remember that one. That's a bit more friendly than the method I gave. (Though not as useful if you actually want the time.  )

The answer is more simpler than you can imagine.
The backslash character '\', when occuring in a string, represents a command for the compiler (tabulator = '\t'). To print a backslash character, you need to use a double-backslash in the string '\\'. To print a double-backslash, you need to use a triple backslash in there '\\\'.

----------------------------------------------
The definition of impossible is strictly dependant
on what we think is possible.

Actually you need four. Each pair of backslashes is interpreted as the literal character '\' by the preprocessor.

Use ("\\\\MyServer\\Direc\\path").

A friend has an interesting problem. He has a site that allows people to register, and once they register they can download an application that will consume data from the site. What he needs is a way for the site to somehow stamp a user's ID onto the application so that when it's downloaded and first run it will immediately know to access the website using that person's info.
I can think of a number of dodgy (and potentially not cross-browser friendly) solutions such as using cookies, dynamically building an install file on the fly in order to include a resource file with the user ID, or even simply asking the user when they first run the app to enter their details, but there must be a simple, neat way that my caffeine starved brain is missing.
cheers,

Here's an (admittedly simple-minded) approach:- The process of registration causes the site to create a user-specific copy of the download app. If the app is
foo.exe, the registration process creates the file foo_1234.exe (where 1234 is the user specific id), if it doesn't already exist.
- The app sends the user's id (gleaned from its filename) in its HTTP request to download data, causing the host to respond with user-specific content.
[edit]
Of course, you should use something more cryptic than just the user's id. Maybe add a timestamp and a checksum at the end.

I thought of that one too but because the user's ID is part of the filename it's open to abuse/spoofing, unless you seed and encrypt the id.

Easily done using MD5 methinks?
Another option would be to download a customer specific encrypted binary datafile (a la the old "license key file"s of yore) that would be accessed by the (generic) app when making the request. There are ways to prevent the license file from being used by the downloader app on another machine.
