Hi!

I have an object which I need to check regularly. I want the following:

1. a member storing when the object was last checked
2. a member storing the length of time between checks

This is for when I run my program if I check the current time vs the last checked time and then determine if the length of time between checks has been exceeded I can then perform an update.

My question is what should I use to store these members? Should I use a SYSTEMTIME structure or is there a better method? Can I compare SYSTEMTIME with the current time and do operations like subtract to find if the length of time between checks is exceeded?

Are there any problems with using SYSTEMTIME?

Something like:

class CMyObject
{
public:
    void Check( void )
    {
        m_timeLastChecked = COleDateTime::GetCurrentTime();
    }
 
    void GetCheckAge( COleDateTimeSpan &timeAge )
    {
        timeAge = COleDateTime::GetCurrentTime() - m_timeLastChecked;
    }
 
private:
    COleDateTime m_timeLastChecked;
};

Thanks

I have never used that class before. Is there any particular reason why to use it instead of SYSTEMTIME or CTime? Looking at it I may also use COleDateTimeSpan to store the time between checks.

A CTime object is only good from January 1970 through January 2038. A COleDateTime object covers that range and a lot more.

What's to store? If you are wanting to know the elapsed time since the last check, you'd be comparing the last-checked time against the current time.

I also need to store a timespan I think. This is so I can store an amount of time like 30 days. I can then decide if an update must be done by looking at the last time an update happened then adding the timespan which is the length of time between updates and then comparing with the current time.

It will be like looking for web updates every 5 10 or 30 days depending on a user setting.

Hi !

I'm trying to develop an hyperterminal-like application in VC++.
I use a CEdit control for logging data coming from a serial com port.

D'Oh! | :doh:

The problem is that I didn't find a good way to add text in the CEdit control.
This works too slow, and gives flickering effects.

Any advise will be welcome !
Thanks in advance.

Jeje.

What way(s) did you find that was not good?

Have you looked at ReplaceSel()?

Yoiu could also add the incoming data to a CString object and then call SetWindowText() once.

msdev.exe debugger

Hello,

I de-installed visual studio.NET. Recently I found out that the de-installer didn't remove the JIT debugger regestry settings from my system.

Now, when a program crashes, the debug dialog appeart and asks me if I want to debug the application. When I hit the retry button (to debug), I get this really annoying message box that says that the JIT debugger canno't be found. It also asks if I want to use the old debugger msdev.exe

After sweeping the geristry manually and removing every VS.NET and JIT entry I could find, the dialog still appears.

Does anyone know how I can solve the problem?

Thanks

I just don't know why I didn't think of enabling the Just In Time debugger from VS 6.0 Mad | :mad:

On the other hand, my registry is clean(er) than it was before

I have the same key, but there was another key: "PreVisualStudio7Debugger". Now I have removed the key..

Hello,

I don't think that there is a function to replace a message to the top of the message qeue. But you can use SendMessage for immediate processing (the message won't be placed in the message qeue)

Check out NetUserEnum(), NetSessionEnum(), and NetWkstaUserEnum().

but it's thread application and the server was with COM technologie developed.
I use one variable iClientsCount it means how much connected clients and i would
like the show this variable in system monitor.

So iterate through each connection and increment iClientsCount. Or, you could look at the fifth parameter which receives the count of items actually iterated. What's wrong with that?

CEvent?

Please bear with me on this post, I have never coded anything in any form of C++ but my boss has given me the task of putting something together that for various reasons requires a C++ application.

The Setup
I have a C# application that launches a background process, this process has to be coded in C++. Fom time to time the C# application will need to close the background process, for various reasons I cannot do a dirty shutdown (i.e. just kill the process). So I am looking for a way of getting the C# app to make the C++ application shutdown cleanly (i.e. process some code before existing).

After doing a far bit of reading I have come across something called CEvent which I understand as being an event that can be fired by external process and caught with the C++ application.

The problem is that although I can easily hold my own in C# I havent got a clue when it comes to C++ so can anybody firstly tell me if I am on the right track, and if so can you point me in the direction of some basic tutorials.

Thanks in advance
