Control the entry in a CSpinEdit

[Papanatix]

Hi everybody. Another doubt:
Does anyone know how can I control when the user puts a letter in a CSpinEdit and not a number, so I can advise him to put a number? (I can only accept numeric data, so I have to control if the user entries a text data instead a numeric data)

Thanksss

I've not used the SpinEdit so I don't know if this will work. On regular edit components, I put a call to a function in the OnExit event. The function then takes the string entered into the component, and in a try...catch statement, trys to convert the string into a number. If the conversion fails, the catch statement spits out a warning and puts the user back on the edit box.

I can show you the code but like I say, I've never used the SpinEdit so I don't know how well that will work.
