Example #1

For example, look at the below code.


Sub CSTR_Example1()

Dim NumericValue As Integer
Dim StringResult As String

NumericValue = 855

StringResult = CStr(NumericValue)

MsgBox StringResult

End Sub
cstr example 1.1

 Firstly I have assigned the Integer data type to the variable “NumericValue” as 855. Now the variable “NumericValue” holds Integer data type. With another variable, “StringResult,” assigned the formula CSTR to convert Integer Data Type to String Data Type.

CSTR converted the integer number to String Data Type. Even though we can still see the number like 855, it is no longer an Integer Date Type in VBAInteger Date Type In VBAIn VBA, an integer is a data type that may be assigned to any variable and used to hold integer values. In VBA, the bracket for the maximum number of integer variables that can be kept is similar to that in other languages. Using the DIM statement, any variable can be defined as an integer variable.read more. It is now in String Data Type.

Example #2

For example, look at an example of VBA Boolean Data TypeVBA Boolean Data TypeBoolean is an inbuilt data type in VBA used for logical references or logical variables. The value this data type holds is either TRUE or FALSE and is used for logical comparison. The declaration of this data type is similar to all the other data types.read more Conversion.


Sub CSTR_Example2()

Dim Val1 As Boolean
Dim Val2 As Boolean

Val1 = True
Val2 = False

MsgBox CStr(Val1) & vbNewLine & CStr(Val2)

End Sub
example 1.3

In the above code, I have declared two variables as Boolean.

Dim Val1 As Boolean

Dim Val2 As Boolean

In the next line, I have assigned Boolean values as TRUE & FALSE.

Val1 = True

Val2 = False

At this point in time, both the variables are Boolean data type. Now in this example, I have applied the VBA CSTR function to convert this Boolean data type to a String Data Type.

example 2.2

Example #3

For example, look at the example of Date Data Type Conversion to String Data Type.


Sub CSTR_Example3()

Dim Date1 As Date
Dim Date2 As Date

Date1 = #10/12/2019#
Date2 = #5/14/2019#

MsgBox CStr(Date1) & vbNewLine & CStr(Date2)

End Sub
VBA cstr example 3.1

Dim Date1 As Date

Dim Date2 As Date

Next line, I have assigned the Date values as 10-12-2019 & 05-14-2019, respectively.

Date1 = #10/12/2019#

Date2 = #5/14/2019#
