Hi Friends,
Can anyone help me in solving this problem. I am able to run my application in Debug mode but not able to run in Release mode.
In my application(MDI application) when I try to open a file it gives "Unreferenced memory 0x000005 - Access Violation" assertion. But, the same is working fine in debug mode.

Try to build your realease build with debug info.

Try adding debugging options to your release configuration so you can track the problem in a debug session:
Compiler: /Zi (if it is an optimizing problem additional try /Od)
Linker: /debug
It is not well known that you can also debug an VC++ app in the "Release Mode" configuration, if you use the above project settings and recompile.
Because MFC and CRT in debug version has many protections against failures sometimes the release version crashes. It is almost a sign for a serious problem in your code even when it dont occur in the debug version. It is a good idea to inspect the debug output (in the debug version) for some warning/diagnostic messages (from MFC/CRT) for getting hints to the problem.

That is an external hardware device. So you will need to check with the manufacturer and find out if they provide any API functions or other tools to acquire this information.

hmm, check to see if it appears as a camera device on your system - if so you could use DirectShow..

How could I override painting of a static control to put some extra text up in top left corner;
_______________
|f1 |
| Static Text |
|______________|
I want the control to draw normally then have my code add the "f1" text in there.
|

There are a number of ways that you can accomplish this, however I would recommend subclassing the edit control and overriding the WM_PAINT message.
You can do this by creating a new WndProc for your static control that handles the WM_PAINT message and sends all other messages to the CallWindowProc.
Then call SetWindowLong using the handle to your static control, and set the GWL_WNDPROC parameter. You will need to cache the value that is returned, because this is the value that you will pass into CallWindowProc in order to get the default static control behavior.
Good Luck

Try the File I/O in the SDK of MSDN. 
If your writing a Windows program why won't you use the MFC CFile in this case?;)

hi,
i was wondering if someone could please help me on a code using arrays. If there is a given date in a year how would i compute and print how many days have passed in that year and also to compute the next day.
For example, if the date was supplied 2/3/98. i understand the null terminator is suppose to be after the day, month and year? but the output should be 61. I also understand that leap years should be taken into account as well being they occur every 4 years.
So far i have determined that i need atleast 4 functions,.. CheckLeapYear, ComputeDays, PrintDays, ComputeNextDay, and PrintNextDate. 
Thank you

I would create an array of 12 items, to represent each of the twelve months, and then in each item in the array I would place the number of days that are in that month.
After you determine which month the requested date is in, you would cycle through your array and add up all of the days until the current month, and add the number of days that have passed in teh current month. Then like you said account for the leapyear.
The other functions that you mentioned can be derived from your data in the month array that I described.
Good Luck

True, that is why I was very careful to only give suggestions for design and no code examples

IsLeap(LONG year) {

(((year % 100) != 0) ||
((year % 400) == 0))) {
return TRUE;
}
else {

What do the values in the lpdwFlags say after you call this function?
I have found that this function is mostly reliable. It will return true if you are connected to a LAN, and it will return TRUE if you are connected to the internet through a modem. But this does not tell you if your LAN is connected to the internet.
I am sure there are other issues if you are connected behind a proxy server, and I am not sure about your Gateway issue.

Hi.
I would like to create a unique icon for an Windows program via MFC. I have a few common questions.
First, what size(s) do the image file(s) have to be? How many images files are required? I remember reading a few weeks back that a program requires two images files for its icon.
Secondly, what format do you have to save the image file in order to import it directly to MFC's Resource Editor?
Thanks,
Kuphryn

In my app I have two icons. One of size 16x16 pixel and the other of size 32x32 pixel.
The best way to create icons is to use the software Microangelo with which you can generate icons and mouse cursors and probably more things...

Okay. Thanks.
If you made two sizes of one icon using Photoshop, how would you import the bitmaps into the resource editor? There is an option to import icons, but not bitmaps. Furthermore, what names do you need to name the icon such that it will replace the old MFC icons?

If you do icons with Photoshop think about using Microangelo (http://www.impactsoft.com/). With this software you can import bitmaps and save them as icons or cursors.
I don't think that you can import bitmaps via Visual Studio directly and store them as icons.
