You can and should do all you can to prevent them, but when they visual basic compile error happen you have to handle them. Introduction Trapping Errors at Run-Time Building Error Handlers Raising Your Own microsoft visual basic compile error Errors Summary Introduction The various functions, statements, properties and methods available in Visual Basic and the components used in Visual Basic expect to deal with visual basic compile error user defined type not defined certain types of data and behavior in your applications. For example, the CDate() function can convert a value to a Date variable. The function is remarkably flexible in the type of information it can accept, but it expects to receive data that

it can use to derive a date. If you provide input that it can't convert, it raises error number 13 - "Type mismatch" - essentially saying "I can't handle this input data." In an application, this type of error may be a program logic error (you simply passed the wrong data) or it may be a data entry error on the part of the user (you asked for a date and the user typed a name). In the first case, you need to debug visual basic compile error sub or function not defined the program to fix the mistake. However, there is no way for you to anticipate the behavior of the end users of the application. If the user enters data you can't handle, you need to deal with the situation. Dealing with errors at run-time is a two step process: Trap the Error Before you can deal with an error, you need to know about it. You use VB's On Error statement to setup an error trap. Handle the Error Code in your error handler may correct an error, ignore it, inform the user of the problem, or deal with it in some other way. You can examine the properties of the Err object to determine the nature of the error. Once the error has been dealt with, you use the Resume statement to return control to the regular flow of the code in the application. In addition to dealing with run-time errors, you may at times want to generate them. This is often done in class modules built as components of ActiveX server DLLs or EXEs. It is considered good programming practice to separate the user interface from the program logic as much as possible, so if a server component cannot deal with an error, it should raise the error in its client application rather than simply display an error message for the user. In VB5, there is an option that allows you to specify that an application has been designed for unattended execution (this is typically used for r

are:Compile Errors;Runtime Errors;Logical Errors ('bugs'). These three VBA error types are discussed in turn, below.Compile ErrorsAuto Syntax Check OptionThe Auto Syntax Check option causes a message http://www.excelfunctions.net/VBA-Error.html box to pop up whenever a syntax error is typed into the visual basic editor.If this option is switched off, the visual basic editor still highlights syntax errors in red.The http://stackoverflow.com/questions/840548/vb6-runtime-error-13-type-mismatch-when-setting-and-int-with-an-int Auto Syntax Check option is accessed by selecting Tools→Options from the menu at the top of the visual basic editor.Compile Errors are recognised by the VBA compiler as being illegal compile error and therefore, are highlighted as errors before your macro even starts to run.If you type in a syntax error, the VBA editor will immediately highlight this, either by popping up a message box or by highlighting the error in red, depending on the setting of the Auto Syntax Check option (see rightabove).Alternatively, a compile error may be detected when the code visual basic compile is compiled, just before being executed.A compile error is generally easy to fix, as the VBA compiler pops up a message box, which provides information on the nature of the error.For example, if you get the message "Compile error: Variable not defined" when you attempt to run your code, this indicates that you are attempting to use, or access, a variable that has not been declared in the current scope. (This error is only generated when you are using Option Explicit). Runtime ErrorsRuntime errors occur during the execution of your code, and cause the code to stop running. This type of VBA error is also relatively easy to fix, as you will be given details of the nature of the error, and shown the location where the code has stopped running.For example, if your code attempts to divide by zero, you will be presented with a message box, which states "Run-time error '11': Division by zero".Depending on the structure of your VBA project, you may be given the option to debug the code, (see below).

Hopefully someone can help me out with a question that I have concerning a Type Mismatch error that I'm receiving from trying to set an int variable with a int returned from a function. The integer that I'm trying to set is defined as: Global AICROSSDOCKStatus As Integer Now when I try to make this call I get the Runtime Error 13 AICROSSDOCKStatus = ProcessQuery(iocode, pb, AICROSSDOCBOLFN, "") I've stepped through debugging the program line for line. The ProcessQuery function gets and returns the expected integer, but when the assignment is to be made to the AICROSSDOCKStatus it fails. On a side note, I've also tried doing a CInt() to the ProcessQuery with the same result. Does anyone have any suggestions for what I may be able to try? Edit: Here is the definition of ProcessQuery Function ProcessQuery(icode As Integer, pb As ADODB.Recordset, TableName As String, sql$) As Integer Edit 2: I couldn't tell you why this was done in this manner. I inherited the code base. Yikes... Function ProcessQuery(icode As Integer, pb As ADODB.Recordset, TableName As String, sql$) As Integer ProcessQuery = ProcessQuery1(icode, pb, TableName, sql$) End Function Function ProcessQuery1(icode As Integer, pb As ADODB.Recordset, TableName As String, sql$) As Integer ''THIS IS THE ORIGINAL SQL CALL ROUTINE! Dim STATUS As Integer On Error GoTo ProcessSQLError STATUS = 0 Select Case icode Case BCLOSE If pb.State 0 Then pb.Close End If Set pb = Nothing STATUS = 3 Case BOPEN STATUS = 9 Set pb = New ADODB.Recordset Case BOPENRO STATUS = 9 Set pb = New ADODB.Recordset Case BGETEQUAL, BGETEQUAL + S_NOWAIT_LOCK, BGETGREATEROREQUAL, BGETGREATEROREQUAL + S_NOWAIT_LOCK If pb.State 0 Then pb.Close ''Set pb = Nothing ''Set pb = New ADODB.Recordset End If pb.Open sql$, MISCO_SQL_DB, adOpenDynamic, adLockOptimistic If Not pb.EOF Then pb.MoveFirst Else STATUS = 9 End If Case BGET_LE, BGET_LE + S_NOWAIT_LOCK If pb.State
