To assist you with identifying them, the Err object is equipped with a property named Number. You can also use the Immediate Window or the other Watch windows to be described later to understand all the values.

Debug.Print Statements The Debug.Print statement lets you write output to the Immediate Window. General Declarations The declarations section should define some variables used by the routines ' Current pointer to the array element of the call stack Private mintStackPointer As Integer ' Array of MsgBox("Choose a button", vbCritical + vbYesNo) the Immediate Window runs the function, then shows its return value. HTH!

Verify Error Handling Setting Before you can use error handling, you need to understand the Error Trapping setting. Otherwise, your code will enter an endless loop, jumping between the line of code that caused the error and the error handling block. Before an error occurs, you would indicate to the compiler where to go if an error occurs. Debugger for VBA and VB6 There are several parts of the debugger that work together to let you analyze how your code runs: Integrated Development Environment (IDE) Breakpoints Stepping Through and

Because there are many types of errors, there are also many numbers, so much that we cannot review all of them. Thatís good, but if this technique is used, before deploying the final version, Stop statements should be eliminated. The error handling block assigns 1 to the variable N, and then causes execution to resume at the statement after the statement that caused the error. Here is an example: Private Sub cmdCalculate_Click() On Error GoTo ThereWasBadCalculation Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an

First of all, create an error form to display when an unexpected error occurs. Instead of letting the program crash, we can provide a number as an alternative. On Error Goto 0 This is also called VBA default exception handling. Without an On Error statement, any run-time error that occurs is fatal: an error message is displayed, and execution stops.Whenever possible, we suggest you use structured exception handling in your code,

Dim x As Integer = 32 Dim y As Integer = 0 Dim z As Integer z = x / y ' Creates a divide by zero error On Error GoTo An active error handler is the code that executes when an error occurs and execution is transferred to another location via a On Error Goto

Unfortunately, users can modify this setting before launching your application so you should make sure this is properly set when your application starts.

Specifically, Resume returns control to the line that generated the error. For example, you can write an arithmetic operation and examine its result. Of course, running a procedure this way only works if you donít have to pass parameters to it. Outside the For Each Next loop, first add the following code line: Exit Sub Without this line, the rest of the code (error code) will be executed, even if there is

In the example, an attempt to divide by zero generates error number 6. This resulted in an error. The other program continues execution at a specified line upon hitting an error. Information about any error that occurs subsequent to line 3 is stored in a VBA error object named 'Err'.

Stop Statement The alternative to using Debug.Assert is to use a Stop statement inside an If clause. In this case you must ensure that your error handling block fixed the problem that caused the initial error. Typical run time errors include attempting to access a non-existent worksheet or workbook, or attempting to divide by zero.

Maybe you want to test it multiple times and donít want to enter it each time on the Immediate Window, or maybe the procedure call is too complex to use in Debugging Views In addition to seeing which line of code runs and evaluating variables as you debug, there are several other views that help you diagnose your development environment: Call Stack Exit Sub 'I was told a long time ago (10+ years) that exit sub was better than end sub...I can't tell you why, so you may not want to put in By looking for it and managing the error if it canít be found, you can determine whether it exists or not.

When there is an error-handling routine, the debugger executes it, which can make debugging more difficult. The term end statement should be taken to mean End Sub , End Function, End Property, or just End. After an error has occurred, to ask the compiler to proceed with the regular flow of the program, type the Resume keyword. Sub GetErr() On Error GoToError_handler: N = 1 / 0    ' cause an error MsgBox "This line will not be executed" Exit Sub Error_handler: MsgBox "exception handler" End Sub In this

For example, to test the UCase$ function, in the Immediate window, you could type: ? Getting information from the error object When an error occurs, information about the problem in the Error Object. Here is an example: Private Sub cmdCalculate_Click() On Error GoTo WrongValue Dim HourlySalary As Double, WeeklyTime As Double Dim WeeklySalary As Double ' One of these two lines could produce an Total Visual CodeTools Total Visual CodeTools will let you takeover existing applications, clean them up, and deliver a more robust solution.

Here's why. Here is an example that tests the result of 275.85 + 88.26: One of the most basic actions you can perform in the Immediate window consists of testing a built-in function. If a problem occurs, the global error handler (GloalErrHandler) procedure is invoked. Hereís an example of deleting a file and providing the user with error messages: Sub DeleteFile(strFileName As String) Dim lngSaveErr As Long Dim strSaveErr As String Const clngErrNoFile As Long =

Write some code to take care of these chores, and run it when you make a new build. Notice that here I have used ‘Exit Sub' just before the ‘Error_handler:' label, this is done to ensure that the Error¬†handler¬†block of code¬†doesn't¬†execute if there is no error. This allows you to skip a section of code if an error occurs. This is extremely powerful and quite amazing when you think about it.

VBA, via the Visual Basic Editor (VBE), is flexible and allows you to determine how it responds to errors. The PopCallStack is called at the end of the procedure to remove the current procedure name from the stack when the procedure completes successfully. A form may close unexpectedly.

Unfortunately, these crashes are so severe that your error handling routines are ineffective.
