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) {

return TRUE;
}

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.

Create a small exe and make your installer program run this exe at the end of the program setup. If you put this exe in the same directory as your service exe it'll be very easy to figure out the path to the service.
int WinMain(...)
{
...
CServiceHelper m_sh;
m_sh.SetServiceDisplayName("Your service description");
m_sh.SetServiceName("Your service name");
m_sh.SetServicePath(strPath);
m_sh.SetAutoStart(true);
m_sh.Create();
...
}

To install a service, you generally use the InstalUtil.exe tool from the command line as:
InstalUtil svcname.exe
To install a service from a setup wizard (in VS.NET), you need to include a Custom Action in your wizard that executes on Commit when the wizard is run. (Take a look at the Custom Actions tab in a VS.NET setup project)
A Custom Action can execute an external .exe or a script. In the situation where you want to install a service, you could execute the InstallUtil in a script that is called as a custom action, or write a console application like the one below using the AssemblyInstaller class. The AssemblyInstaller loads an assembly, and runs all the installers in it.
To use the AssemblyInstaller, you need to include an Installer class in your service that registers your service.
There is not enough time for me to discuss all the details, but you may want to take a look at the AssemblyInstaller and the ServiceInstaller classes.
The following is the example given in the docs for the AssemblyInstaller class:
using System;
using System.Configuration.Install;
using System.Collections;
using System.Collections.Specialized;
class AssemblyInstaller_Example
{
static void Main()
{
IDictionary mySavedState = new Hashtable();
Console.WriteLine( "" );
try
{
// Set the commandline argument array for 'logfile'.
string[] commandLineOptions = new string[ 1 ] {"/LogFile=example.log"};
// Create an object of the 'AssemblyInstaller' class.
AssemblyInstaller myAssemblyInstaller = new
AssemblyInstaller( "MyAssembly.exe" , commandLineOptions );
myAssemblyInstaller.UseNewContext = true;
// Install the 'MyAssembly' assembly.
myAssemblyInstaller.Install( mySavedState );
// Commit the 'MyAssembly' assembly.
myAssemblyInstaller.Commit( mySavedState );
}
catch (ArgumentException)
{
}
catch (Exception e)
{
Console.WriteLine( e.Message );
}
}
}
To help you get started, an example Installer implementation will look something like this:
[RunInstallerAttribute(true)]
public class MyServiceInstaller : Installer
{
private ServiceInstaller _installer;
private ServiceProcessInstaller _processInstaller;
public MyServiceInstaller()
{
InstallServices();
}
public void InstallServices()
{
_processInstaller = new ServiceProcessInstaller();
_processInstaller.Password = null;
_processInstaller.Username = null;
_processInstaller.Account = ServiceAccount.LocalSystem;
Installers.Add(_processInstaller);
// Add each service to installer
_installer = new ServiceInstaller();
_installer.StartType = ServiceStartMode.Manual;
_installer.ServiceName = "YourServiceName";
_installer.DisplayName = "YourServiceDisplayName";
Installers.Add(_installer);
}
}
There may be typos above, but the intention is to point you to the right classes to use.

if the software appears in add/remove program then i can go to registry
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
and look for uninstallString key.
but what is the rest of procedure to uninstall a software programatically?
i dont know how to get uninstallString key and how to run it in a program.can any body help me in this regard?
any example link where registry keys are used and run programatically. if u could provide i would be very thank full to you?

Most installers will automatically create an uninstaller for you. If you want to give a short cut to that in your start menu folder, just locate the name of the uninstall executable. It might not even be an exe and might be in the msi uninstaller format.

I was under the impression that underneath the uninstallString key, there were some other keys. For isntance, if your app is called (creatively) YourApp:
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\YourApp
should contain a string value named UninstallPath that contains a path to the uninstall executable.
I am not sure how programs installed via MSI do this - it may be different.
Of couse, this is dependent on the program's installer behaving correctly and putting the correct registry keys there in the first place.

infect i never used registry and its keys in a program.

There are Windows APIs to read registries, as well as some articles here on CodeProjet. Check out RegOpenKey in MSDN for starters. Basically, you open a registry key, and you can then get data from values. Then close the key when you're done.
(I'd post some code, but I'm at my home computer at the moment and don't have any code with me.  )

hi,
My questions are:
1. How to link a MFC DLL to an exe file with DEF file
2. How to export an function without use of header file
Thanks

Although it's not the focus of this article, it does have a little info on .DEF files... and also a comparison of the various ways to export functions from a DLL.
Hope this helps.

Im developing an NDIS adapter driver, to pass standard TCP/IP traffic over a nonstandard medium, and am having problems with ICMP echo request/replies. With the driver set up on 2 machines (IPs 1.2.3.4 and 1.2.3.5), I can drop to a command prompt on 1.2.3.4 and ping 1.2.3.5. An ARP is given to my driver, which is sent to the broadcast address, and 1.2.3.5 sends an ARP reply back to 1.2.3.4. An ICMP echo request is then transmitted from 1.2.3.4 to 1.2.3.5, and it is sent through my driver to 1.2.3.5. It appears to be successful in transmission, as the packet is packaged up in an NDIS_PACKET, and sent up to NDIS, and NDIS calls my MiniportReturnPacket function, however 1.2.3.5 never generates an ICMP reply. I have verified that the IPs and subnet masks are set up correctly, and that even though Im using the same driver on both machines, the MAC address's are unique. Anyone have any ideas as to what could be wrong? Thanks in advance.

Hello,
i have a bitmap in my iPAQ and i want to send with socket; my code is
int nBmpsize;
char *szBuff;
GetObject("\\Windows\\Start Menu\\front2.bmp", sizeof(BITMAP), &bitmap);
nBmpsize = bitmap.bmWidth*bitmap.bmHeight;
szBuff = new char[nBmpsize];
memcpy((void*)szBuff, bitmap.bmBits, nBmpsize);
but i have some problem. Why?
|

'some problem' does not give us much to go on. for starters, try making it an unsigned char buffer, a char buffer has a maximum value of 127. What is GetObject ? Also, bitmap.bmWidth * bitmap.bmHeight will give you the number of bits in a word aligned, one bit image ( that has only two colours ). You need to multiply by your bit depth and you need to add a stride value to the width before multiplying. My articles on Image Processing show how to calculate stride.
