the wrong time. The application may crash. A calculation may produce unexpected results, etc. You can predict some of these effects and take appropriate actions. Some other problems are not under your control. Fortunately, both Microsoft Excel compile error in hidden module registrationdb and the VBA language provide various tools or means of dealing with errors.

One way you can do this is to prepare your code for errors. When an error occurs, you would present a message to the user to make him/her aware of the issue (the error). To prepare a message, you create a section of code in the procedure where the error would occur. To start that section, you create a label. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: End http://www.functionx.com/vbaexcel/Lesson26.htm Sub After (under) the label, you can specify your message. Most of the time, you formulate the message using a message box. Here is an example: Private Sub cmdCalculate_Click() ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub If you simply create a label and its message like this, its section would always execute: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalary = FormatNumber(WeeklySalary) ThereWasBadCalculation: MsgBox "There was a problem when performing the calculation" End Sub To avoid this, you should find a way to interrupt the flow of the program before the label section. One way you can do this is to add a line marked Exit Sub before the label. This would be done as follows: Private Sub cmdCalculate_Click() Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an error, such as ' if the user types an invalid number HourlySalary = CDbl(txtHourlySalary) WeeklyTime = CDbl(txtWeeklyTime) ' If there was an error, the flow would jump to the label WeeklySalary = HourlySalary * WeeklyTime txtWeeklySalar

These best practices will help ensure your apps run as intended, without a hitch. By Susan Harkins | in Five Apps, October 9, 2010, 1:15 AM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus A professional application always includes adequate error-handling routines to trap unexpected errors. Sometimes, the right handling means the user never knows the error occurred. At the very least, error-handling routines should address the problem, share adequate information on what the user should do next, and exit the program (if absolutely necessary) gracefully. You put a lot of effort into writing the procedures that run your custom applications. Why let a runtime error ruin it all? By employing a few best practices, you can improve error handling. 1: Verify and configure error settings Before you do anything, check the error-trapping settings. VBA, via the Visual Basic Editor (VBE), is flexible and allows you to determine how it responds to errors. To access these settings (shown in Figure A), in the VBE, choose Options from the Tools menu, and click the General tab: Break On All Errors: Stops on every error, even errors following a Resume Next statement. Break On Unhandled Errors: Stops for unhandled errors, but stops on the line calling the class (in class modules) rather than the line with the error, which can be problematic during debugging. Break In Class Modules: Stops at the actual error (line of code), but doesn't work as expected with Err.Raise, which g
