Thanks for the reply. I am trying to fire an event from c# and this to be listened to by vb6 com.

I think it would be very hard to do in javascript - and very slow. But here is a good place to start:

This speeds the code up:


private string StringReverse(string ToReverse)
{
Array arr = ToReverse.ToCharArray();
Array.Reverse(arr); // reverse the...

This one will return a doube


private double GetNumericValue(string sVal)
{
int iFirst, iEnd;
char[] aNumbers = "1234567890.-".ToCharArray();

I use this - it seems to be faster, however, same as the others, it only works for positive integers:


private int GetNumericValue(string sVal)
{
int iFirst,...

Try this:



Dim daCtrl As ComboBox

Thanks thats really helped me out.

Candles stay lit because the heat they produce causes the carbon dioxide, they produce, to rise. Oxygen fills the space and the cycle keeps going. However during freefall the carbon dioxide doesn't...

But because the sphere is falling - there is no convection, so the oxygen wont replace the carbon dioxide. So the candle had no oxygen to burn and hence it could go out.

Another alternitive is...

No the sphere can be opened - light the candle - close it and drop. The 60 seconds of air time starts from the drop.

Here is a strange one, I am not sure of the answer myself:

You have a glass sphere. There is a place in the centre of the sphere for a candle. There is enough air in the sphere to keep the candle...

I think it is something to do with the control being sent the string from xml, which is of the form "μ" - this is µ.
