It finds one error each time you use it.Debug->Compile finds compilation(project wide) errors.This means your application has no compilation errors at the current time. However, “Compile” will be grayed out in the Debug menu. If there are no errors left and you run Debug->Compile, it may appear that nothing happened. When this error is fixed, you can run Compile again and VBA will then find the next error.ĭebug->Compile will also include syntax errors in it’s search which is very useful. When you select Debug->Compile, VBA displays the first error it comes across. To find compilation errors, we use Debug->Compile VBA Project from the Visual Basic menu. The following screenshot shows a compilation error that occurs when a For loop has no matching Next statement. Variables not declared( Option Explicit must be present at the top of the module).Giving a Sub or Function the same name as a module.Calling a Sub or Function with the wrong parameters.Calling a Sub or Function that does not exist.If statement without corresponding End If statement.

The syntax is correct on a single line but is incorrect when all the project code is taken into account. The line will still appear red if there is an error but the dialog will not appear.Ĭompilation errors occur over more than one line. Note: You can turn off the Syntax error dialog by going to Tools->Options and checking off “Auto Syntax Check”. They occur when the syntax of one line is incorrect. Some examples of syntax errors are ' then is missing If a > b When you type a line and press return, VBA will evaluate the syntax and if it is not correct it will display an error message.įor example if you type If and forget the Then keyword, VBA will display the following error message

If you have used VBA for any length of time you will have seen a syntax error.

Let’s have a look at each of these error types so that it is clear what a runtime error is. We use error handling to deal with runtime errors. To understand error handling we must first understand the different types of errors in VBA. They allow our application to deal gracefully with any errors we weren’t expecting. This is where the VBA error handling statement comes into play. If we think an error is likely to occur at some point, it is good practice to write specific code to handle the error if it occurs and deal with it.įor all other errors, we use generic code to deal with them.

These errors are normally caused by something outside your control like a missing file, database being unavailable, data being invalid etc.

( Note: Archive members have access to the webinar archive.)Įrror Handling refers to code that is written to handle errors which occur when your application is running. Members of the Webinar Archives can access the webinar for this article by clicking on the image below. Returns the error text from an error number. You can populate this when you use Err.Raise.Ī function that allows you to generate your own error. (Only useful if you need to check a specific error occurred.) When an error occurs the error information is stored here. Goes to a specific label when an error occurs. When error occurs, the code stops and displays the error.Ĭlears the current error setting and reverts to the default. 5.4 Runtime Errors that are not VBA Errors.5.3.1 Expected Versus Unexpected Errors.
