Vbcodes in timer

The GameTile class is overly-simple and just has an OnInput and OnDraw logic processing routine for the engine to call. In a more robust model, there would be additional logic processing methods which would get called at various appropriate points throughout each execution of the game engine loop. As previously noted, this is not ideal as the event chain is less efficient for our purposes than running a background thread would be, but the timer keeps the example simple. First, we update the time based on how long the last frame took to execute.

Vbcodes in timer

It seems to be correct for most standard operations.

For example, I found just putting a Debug. Print statement in the timer event causes the timer to crash when you try to terminate it.

Putting methods there to raise an event directly also caused an untimely crash.

You really don't want to have to try to deal with the IDE locking up every time you set a break-point. Once it is in the DLL then the next thing is to consider how to reduce the number of timer instances to ensure you aren't too likely to run out of them.

In this code, the timer itself is implemented in a module. If you implement code in a module, this module will be global to all classes which use it within a process.

Therefore it is possible to create a single timer to service as many classes as you want. The trick is to ensure that the module doesn't get a reference to the classes that are attached, otherwise you will get a circular reference.

Vbcodes in timer can prevent circular references by storing object pointers rather than direct references to classes as described in the article Subclassing without the crashes. The final problem to work around is that you can only call a very limited selection of functions during a multimedia timer event.

I work around this by using the PostMessage function. The form is subclassed by the DLL so when the custom message is received it is intercepted by the hidden form's WindowProc function, and this allows the module to forward the message on as an event to any objects which are using the DLL.

This method of working may seem rather stupid - a timer event is received by the DLL's timer module, then posted to a form and intercepted from the form using the same DLL - but it turns out this is vital to ensure the timer is stable during operation.

There are various examples of how to crash your system by not doing this available elsewhere on the Internet no names - you know who you are: When using the DLL provided with the download, you can get stable crash-free operation.

Something you should have changed before 2000 (#y2k)

Even if you set the timer to do something at a silly rate which your code can't keep up with you shouldn't have difficulty provided you use the Event interface, because the PostMessage operation prevents things going wrong.

However, I should point out if you are running the DLL code in the group project, no such niceties apply. No point giving disclaimers about when and how you will crash - you will!

It isn't a problem though, just restart VB. If you're interested in building this code into your project, I strongly advise using the DLL to begin with and then only incorporate the code when you come to make the EXE. Using the HiRes Timer The HiRes Timer offers a simple way of adding and removing timers, and there are two ways of receiving timer events the Third Way, as proposed by UK's increasingly bizarre Prime Minister, will not be made available here.

Responding to timers the first way involves setting up the class as WithEvents. If you do this, the timer will call the Timer event every time it fires. This is the simplest and easiest to debug method to use. The second way of receiving timer events is via an implemented interface.

If you do this, you should use the Connect method to specify the object which receives the timer notifications. By doing this, you create an early-bound interface between your code and the Timer, and you receive notifications with the minimum of system overhead.

This method is the fastest but can cause trouble as it can occasionally overwhelm VB's IDE with event calls whilst you are debugging, something which can't happen with the event interface. The best idea is to use the Events interface for development and then switch to the implementation method for compiled executables.

On my Win95 system, the High-Resolution version manages to fire 40x more events than the standard VB version. This offers extra interfaces such as a countdown timer and an About screen Hmmm.
