In some programs they convert the date to a number. (eg. like CTime class) then you can detect real easy is bigger or smaller and just substract or add them.

I would take in account that in the year 2004 february has 29 days... leap years.

good luck.

Hello,

Think it goes something like this, but you should check on web ...

if year is divisible by 4 then
....if year is not divisible by 100 then
.........it's a leap year
....else
.........if year is divisible by 400 then
...............it's a leap year
.........endif
....endif
endif

Hello,

This mightn't be exactly what your asking but you should make the '-' operator a 'friend' rather than a class member. It means you can use it like the built-in subtraction operator instead of call a method.

ActiveX Registration

Hello,
my MFC dialog based app uses a freeware activex I found on the net.

To use it, the relative ocx file must be registered in the system.

Is there a way to make the app do itself without the user having
to run regsvr32 c:\..... ?
i.e. to register at execution and unregister on close app?

Thanks for the precious help.

Marco.

Does ALU inside the cpu handle floating point? or cpu will let the FPU handle it?

Does ALU inside the cpu handle floating point?
or cpu will let the FPU handle it? For example,
when we declare float, or double?

Another newbie's question:
When we do assambly language, we will specify
which register to use, so my question is: do
we need to have to specify when to use cache?
or the cpu will just simply decide when to use
cache itself?

Run Windows Installer in background

Hello everyone!
I'm not quite sure, if this is the correct message board for this thread, but i'm working with C++ so I posted this thread here.

I've created an Win32 Application, which checks if the .net Framework is installed on the system. If not, the program will automatically start to install the .net Framework in the background.

Is there any way to run a Windows Installer Package in the background (command line, etc.)??

For example I have myinstaller.msi or dotnetfx.exe!

How can I solve my problem???

Thank you for helping me!

You can execute the EXE file with CreatePRocess() and either wait for it to finish or not.
You can run MSIEXEC to run MSI files. You can wait, or not, for the setup to finish.
Now, I have not installed .NET so many times to know if it usually requires a reboot or not. If it usually requires a reboot, then you might as well launch its setup and exit, since the machine will probably have to be restarted anyway.

Check out this article on starting another program from your current program:

You need to call CreateProcess to start the MSIEXEC program which will run the MSI file you use to install .NET

How to use msadox.dll and msado15.dll together in same file

I want to write a function in VC++ which will create a table(in a new mdb file) in MsAccess and also fill the table with values in the same function. As for creating the database i have to use msadox.dll and for populating database i have to use msado15.dll. But if i import both these dlls i get the following error.
< error C2011: 'DataTypeEnum' : 'enum' type redefinition >
This is probably due to DataTypeEnum being defined in both msadox.tlh and msado15.tlh.
Is there any way in which i can use both the dlls
or any other way i can create and populate the table in same function.
Note :(I got to create database in Access 2000)

With Regards,
Kaustubh

I did come across this conflict a while back when I needed to use ADO, ADOX and JRO (JET compression).
Try this:

<font color=green>// Import database COM interface headers

#pragma warning(push)
#pragma warning(disable:4146)
	
#import "C:\Program Files\Common Files\system\ado\msadox.dll"

using namespace ADODB;

Delete the code for the class, and ClassView will update itself automagically.

hi Frank,

sorry, that i misquoted the problem..
the problem does not come when i statically link the application. but when i run the application a system without VC++ installed, it gives the following error:

Debug Assertion Failed:
Program: C:\xyz.exe
File: map_pp.cpp
Line :128

the map_pp.cpp is a MFC file. so i do not where the probwm is. It runs fine on a machine which has VC++ installed in it.

i also want to know if there is some other way other than static linking, such that i can run by application on any windows machine irrespective of whether VC++ is installed on that machine.
Please reply soon,

CMemoryState can't help you on this as it could only detect new and delete.

How about _CrtMemState, _CrtMemCheckpoint and the supporting APIs used for _malloc_dbg?
