VBC09310 — Type mismatch

Severity: Error · Family: VBC (static semantics / abstract syntax tree) · Source metadata: VBCompileErrorInfo

A value is of a type that cannot be let-coerced to the type it is assigned to, passed as, or compared against.

MS-VBA reports the same error, at compile time and at run time: Type mismatch. The run-time error is VBR00013.

How it is raised

Situation	Example	Resolution
An operand or a value is of a type the operation or the target cannot take.	`Dim n As Long: n = Array(1, 2)`	Convert, or use the right type.
An object whose default member returns an object is where a value of a declared type is expected (RD-VBAL §5.5.1.1).	`n = New Holder`, where `Holder`'s default member is `As Object`	Read the value of the object it returns (`n = holder.Value.Value`), or declare the default member with the type of its value.
A subscript of an array is a `LongLong` (RD-VBAL §5.6.13), whatever its value.	`Dim ll As LongLong: Debug.Print a(ll)`	Convert it: `a(CLng(ll))`.
A conditional-compilation condition is not a number or a `Boolean`, or does not evaluate.	`#If "a" Then`, `#If 1 / 0 Then`	Write a number or a `Boolean` expression.
