Using CInt() on textbox value causes "type mismatch"

[slicendice]

Hi
I have a very simple bit of code that is trying to do a CInt conversion on the numerical content of a textbox (i.e. make it an Int if a decimal has been specified). The line of code in question is:

txtMWMins(Index).Text = CStr(CInt(txtMWMins(Index).Text))

However I get a "type mismatch" error occurring and I'm not too sure why! I've tried just a simple type conversion using:

Dim x as Integer
x = CInt(txtMWMins(Index).Text)

but get exactly the same problem!

Thanks

Is variable Index in scope when you run the line? In other words did you try with a fixed value in place of Index

Sorry, I should have mentioned that! The code is for a control that is part of a control array - "Index" is just the index of the control in question

DOH DOH DOH!!!!

Apologies! Just found out the prob.....the event was getting fired before txtMWMins(Index).Text had a value in it, so it was tryring to do a CInt() on a null string!

Strangely enough, it all seems to work fine now I've put a check for vbNullString before doing the conversion!

Sorry about that - was just me being a numb-nuts!

Thanks johnwm
