Re: Date Format Conversion

Andreas,


Thanks for you answer, (in fact, I'm using your code to get the lines 
of the .txt file) but I don't want to give up so easily nor I think 
it is so obvious.

It is impossible to say what 03/04/06 means, when you analyze it 
alone, out of any context.

But that's not the case. Let me give you  some extra info (just take 
this assumptions for granted):

1. The .txt was generated by another application, and most likely at 
the same machine, using the same current date format setting.
2. This will be a one-operation-followed-by-the-other. I mean, the 
user probably will export the .txt file from the old application, and 
import it at  MyApp in the next moment.
3. The old app exports ONLY in dd/mm/yy or mm/dd/yy.
4. There will be always hundreds of "elements" in the tempArray.

At the present, the user will have to input the dates manually, so 
anything I can do to make this task easier, may help him.
With all this info in mind, I can think of a couple of ideas to, at 
least, try to help the user on this issue...just don't know to 
implement them.

For example:

1. The .txt file was created by the same user, probably using the 
same date format he is using (yes...this may not be true...but assume 
it is true). So the app may get the current system date format and 
act accordingly.

2. Since there will be more than one hundred entries (assume this is 
true), the app may check the two first characters of the date string, 
and look for a value higher than 12. If it finds, it uses dd/mm/yy

3. As a last option, I may add a pop up that asks the user to inform 
if the date is dd/mm/yy or mm/dd/yy, but it will be a lot better if 
the application was able to find it out by itself.

Anyway...just thoughts, because I don't know how to implement the 
"checkCurrentSystemDateFormat" or the "checkFirstTwoCharacters" methods.
