Textbox validating event

I want to check what the user is writing in a textbox before I save it in a database. I guess I can always write some ifs or some try-catch blocks, but I was wondering if there's a better method.

Many times it is necessary for a C# Textbox control to only receive only numbers as input.

A common technique used is to check the text to make sure it is a number and throw an exception if it is not. We can make a C# Textbox accept only numbers (integers).

When outputting a new document in the Create and Send New Document window an error that JCS can't find the form 'Admin Docs Reg New' would appear.

This issue only affected JCS versions 27.000.21 and 27.000.22 and has now been fixed.

If you are using a VBA Userform, you are almost surely using the Text Box control, and in many of these circumstances you may wish to restrict what sort of data the user is allowed to enter, such as numeric only.

Unfortunately, there is no built-in property to restrict a text box to numeric only.

When printing labels from a new document in the Create and Send New Document window an error that JCS can't find the form 'Admin Docs Reg New' would appear.

This issue only affected JCS versions 27.000.21 to 27.000.25 and has now been fixed.

Similarly, the Clients Report's speed has been improved and the drop down lists of Client Names and Client Numbers will now be far more responsive.

Electronic statements from Scottish Widows would have been imported into JCS, showing as multiple separate statements, when they should have been a single statement with multiple payments.
