I suggest trying to input a string instead, then you can count the number of digits after the decimal using a loop of some kind.  Then when you are all done checking the number of digits, remove any of the excess by setting them to '\0'.  Lastly you can convert the string to a float using something like atof.

See if you can use the Microsoft Masked Edit ActiveX control.  Add it to your project with 'Project - Add to Control - Registered ActiveX controls'. Then set the mask to 99999.99 for currency format.  Then grab the string from the edit field and convert the string to a float per thresher.

Thanks Thresh, Phillip - I certainly appreciate the response. I have a question regarding your answer, how do I get the input process to look like its accepting a number only (it is a currency field), and are there any intrinsic functions to do the rounding for me ?

I did read somewhere about a COLECurrency object ?

The 9999.99 or ####.## type mask (I can't remember which is correct) should only allow numbers.  What's missing?

> Are there any intrinsic functions to do the rounding for me ?

No.  You'd have to write something manual.

> COleCurrency object?

is a way to store and handle the numbers once you receive them from the input device.  It really doesn't help you much during the input procedure.

I must say that I'm surpised at the lack of intrinsic rounding.

Regarding the mask, I am presuming that this works for output too, so all I can say as a newbie is thanks for all your help, gentlemen.
