Re: Datatype checking in DotNET

You can use a function called StrToFloat (There is other variations of this function also ie. StrToFloatF)

I've never seen DotNet, but there is probably some method of a Double class, for instance, that attempts a conversion from a string to a double and will throw an error or give a return code if the string isn't a valid double.

Hi Nicholas,

Hi Nicholas,

Yeah I am doing that now at the moment for example as based on the given example previously:-

I use StrToFloat, if this fails, it raises an exception (Which is fine of course).

But what I am trying to achieve here is to ensure the data integrity, does the data meet the float bounds?????

For integers you could do a test like this:-

tempVal := StrToInt (fieldStr);
if (tempVal < low (IntImSavingToo )) or (tempVal > high (IntImSavingToo )) then
exit;
IntImSavingToo := tempVal;

Is there something I can use for floats, doubles and singles also???
