Excel vba call sub from sub

This tutorial will teach you how to call a sub procedure from within another sub procedure in VBA

It is very useful to write code that can be used repetitively, and called from multiple sub procedures in your project – it can save an enormous amount of time and makes the VBA code far more efficient.

Running a Sub Procedure from another Sub Procedure

Consider the 3 Sub Procedures below:

Sub TestRoutine()
   RunRoutine1
   RunRoutine2
End Sub

Sub RunRoutine1()
   MsgBox "Good Morning"
End Sub

Sub RunRoutine2()
   MsgBox "Today's date is " & Format(Date, "mm/dd/yyyy")
End Sub

If we run the Sub Procedure – TestRoutine – it will call RunRoutine1 and RunRoutine2 and 2 message boxes will appear.

There is no limit to the number of Sub Procedures you can call from another Sub Procedure.

Using the Call Statement

You can also use the Call Statement in front of the procedure name, to make your code easier to read.   However, it has no effect whatsoever on how the code is run or stored.

Sub TestRoutine() 
   Call RunRoutine1 
   Call RunRoutine2 
End Sub

Calling a Sub with Arguments

It is also possible to call a sub with arguments

Sub TestRoutine() 
   RunRoutine1 ("Melanie")
   RunRoutine2 ("Have a lovely Day")
End Sub

Sub RunRoutine1(strName as String) 
   MsgBox "Good Morning " & " & strName
End Sub

Sub RunRoutine2(strMessage as String ) 
   MsgBox "Today's date is " & Format(Date, "mm/dd/yyyy")  & VbCrLf & strMessage
End Sub

Calling a Sub with Named Arguments

If you name your arguments, you don’t have to pass them in the same order to your sub routines.

Sub TestRoutine() 
   RunRoutine1 strGreeting:="How are you?", strName:="Melanie"
End Sub

Sub RunRoutine1(strName as String, strGreeting as string  
MsgBox "Good Morning " & " & strName & vbCrLf & strGreeting 
End Sub

Calling Sub and Function procedures

To call a Sub procedure from another procedure, type the name of the procedure and include values for any required arguments. The Call statement is not required, but if you use it, you must enclose any arguments in parentheses.

Use a Sub procedure to organize other procedures so they are easier to understand and debug. In the following example, the Sub procedure Main calls the Sub procedure MultiBeep , passing the value 56 for its argument.

After MultiBeep runs, control returns to Main , and Main calls the Sub procedure Message . Message displays a message box; when the user clicks OK, control returns to Main , and Main finishes.

Call Sub procedures with more than one argument

The following example shows two ways to call a Sub procedure with more than one argument. The second time it is called, parentheses are required around the arguments because the Call statement is used.

Use parentheses when calling function procedures

To use the return value of a function, assign the function to a variable and enclose the arguments in parentheses, as shown in the following example.

If you are not interested in the return value of a function, you can call a function the same way you call a Sub procedure. Omit the parentheses, list the arguments, and don’t assign the function to a variable, as shown in the following example.

If you include parentheses in the preceding example, the statement causes a syntax error.

Pass named arguments

A statement in a Sub or Function procedure can pass values to called procedures by using named arguments. You can list named arguments in any order. A named argument consists of the name of the argument followed by a colon and an equal sign (:=), and the value assigned to the argument.

The following example calls the MsgBox function by using named arguments with no return value.

The following example calls the MsgBox function by using named arguments. The return value is assigned to the variable.

VBA Sub

Excel VBA Sub Procedure

SUB in VBA is also known as a subroutine or a procedure that contains all the code. It is an inbuilt statement in VBA, and when used, it automatically gives us the statement of the end sub. The middle portion one may use for coding, the sub statement can be both public and private, and the subprocedure’s name is mandatory in VBA.

Sub means Sub Procedure in VBA. Sub Procedures are used to perform a specific set of tasks provided in the form of code. It performs only the task mentioned in the code as per the VBA language but does not return any value.

How to write VBA Sub Procedures?

It is important to understand the structure of the sub procedure to write sub procedure codes. Below is the structure.

To start the sub procedure, we need to use the word “Sub.” We need to give a name to the Sub as a procedure name. Procedure Name is nothing but our macro name. We do not usually have parameters inside the parenthesis in the VBA sub procedure.

After writing the Sub Procedure name, we need to write the tasks that we need to do. Then comes the End statement, i.e., End Sub.

Example #1 – Simple Sub Procedure

Now, take a look at the simple sub procedure writing methods.

Step 1: Start the word “Sub” in the module.

Step 2: Now name the macro name or procedure name.

Step 3: After giving the name to the sub procedure, just hit the enter key. It will automatically apply the end statement.

Now, we can see two things here, one is the start, and another is the end of the subprocedure. For better understanding, we can call it “Head” and “Tail.”

Between the head and tail of the macro, we need to write our code to perform some tasks.

Example #2 – Simple Subroutine Task

Now, we will see how to perform some simple actions here.

Assume you want to insert the value “Excel VBA” in cell A1.

Step 1: Start the sub procedure by using the above methods.

Code:

Step 2: To access cell A1 we need to use the word RANGE.

Code:

Step 3: It asks what cell1 you want to refer to is? In this case, it is an A1 cell.

Code:

Step 4: We need to insert the value “Excel VBA,” so select the VALUE property by putting a dot after the range.

Code:

When you start typing the word VALUE, you will see many options. These options are called an IntelliSense list, which predicts based on your typing. It is like how formulas will appear in the worksheet when we start typing the formula.

Step 5: After selecting VALUE, put an equal sign and enter the value in doubles quotes as “Excel VBA.”

Code:

So, we have completed it.

Now, we need to execute this task. To execute the task, we had a return. So, we need to run this code by pressing the RUN button in the visual basic editor window.

As soon as you run the code, you will get the “Excel VBA” value in cell A1.

Types of VBA Subroutine

We have two more types in sub procedure: Public Sub Procedure and Private Sub Procedure.

The words “Public” and “Private” are accessibility modifiers that allow us to use them differently.

• Public Sub Procedure allows us to use the procedure in all the workbook modules.
• Private Sub Procedure allows us to use the procedure only in the current module.

For example, look at the below image of the Public Code, which is there in Module 1.

Now, in Module 2 also, we can use this sub procedure.

Action1 is the name of the sub procedure we have used in Module 1.

In Module 2, we have mentioned it as “Call Action1”. It means when you run the sub procedure, it will execute the subprocedure Action1 from Module 1.

One cannot access Private Sub Procedures from a different module. We need to access them from the same module only.

VBA Call Sub

What is Call Sub in VBA?

Sometimes, we may need to write a huge amount of code, and writing them in a single macro creates many problems while debugging the code. Unfortunately, at the start, everybody tends to do this purely because of the lack of knowledge of the “Call Sub” method.

Keeping all the codes in a single sub procedure is not a good practice. Instead, we need to break them into multiple sub procedures to simplify the code.

How to Call Subroutine in Excel VBA?

In the above image, we have two subprocedures. The first one is “Code_1,” and the second one is “Code_2”.

In the first VBA call subcode, we just wrote a code to insert a value to cell A1 as “Hello.” In the second sub procedure, we have written the code to change the interior color of cell A1 to “rgbAquamarine.”

We will run the first code, “Code_1”.

We will run the second code, “Code_2”.

Here, we have executed the code times.

By using the VBA “call Sub,” we can execute both the sub procedures in a single macro. First, we need to add the word “Call,” followed by a macro name.

Look at the below graphic picture.

We have only mentioned the code as “Call Code_2” in the first subprocedure. Now to understand, let us run the code line by line. Press the F8 key. It will highlight the macro name.

Press the F8 key one more time. It will jump to the next line.

The yellow-colored line shows the highlighted code is about to execute if we press the F8 key again. Press the F8 key now.

As we can see, it has inserted the word “Hello” into cell A1. So now, the “Call Code_2” line highlights.

“Call Code_2” has the task of changing the interior color of cell A1 and the word “Call Code_2” will execute this code from the actual sub procedure only.

But press the F8 key to see the magic.

It has jumped to the mentioned sub procedure name. Press the F8 key once again.

Now, the actual task line highlights. To execute this, press the F8 key one more time.

Like this, we can execute many sub-procedures from one sub procedure by calling the sub procedure by its name “Call.”

Note:

• We can execute the macro of another sub procedure without using the word “Call” but just by mentioning the macro name itself.
• It is not the best practice because if the macro sub procedure contains parenthesis that you want to execute, then the “Call” word is mandatory.
• We always think of using the word “Call” because it is just a four-letter word, allowing others to understand the code correctly.
