Call another sub vba
It does not make a difference if you call a built-in or a custom procedure. To call a Sub procedure from another procedure, type the name of the procedure and include values for any required arguments. You usually call Sub procedures to achieve side effect s:. The normal use of a function is to assign the value returned by the function to a variable. To use the return value of a function, assign the function to a variable and enclose the arguments in parentheses.
An example is calling the built-in Date function:. If the functions return type is an object instead of a built-in type it is preceeded by the keyword Sete. You may also call a function in arguments to functions. One feature of VB that makes it easy to use is that it is not strict about types.
VB will automatically try to interpret what you assign so that it can continue. If you want your procedure to returning multiple values, for example a function TopLeftCoords.
Now there are two approaches:. Note: if you want to try the below code, at least the Type definition needs to be in a standard module. The most commonly used way of calling a function is using arguments position.
If you see such code, or have to write it, a recurring question is what it actually does. Ok, you know it does a replace. But which string is being replaced in where by what? And will it replace 'aB' by 'ac'? To see what's what you can put the cursor inside the function call and insert a space, which opens a tooltip, see below. A more definite way however is to use explicit arguments. When using the Code VBA add-in using default settings you will call procedures with explicit arguments in which case the code looks like.
Related Creating a Sub or Function procedure Call a Sub To call a Sub procedure from another procedure, type the name of the procedure and include values for any required arguments. Test" The first Sub is built-in, the second would be a custom Sub you wrote. Call a Function The normal use of a function is to assign the value returned by the function to a variable.A subroutine is a piece of code that performs a specific task and does not return a result. Subroutines are used to break down large pieces code into small manageable parts.
Let's say you have created a user interface with text boxes for accepting user input data. You can create a subroutine that clears the contents of the text boxes. A subroutine is appropriate in such a scenario because you do not want to return any results. This introduces complexity. Subroutines help solve this problem by breaking down the program into small manageable chunks of code. Code reusability. Let's say you have a program that needs to access the database, almost all of the windows in the program will need to interact with the database.
Instead of writing separate code for these windows, you can create a function that handles all database interactions. You can then call it from whichever window you want.
Subroutines and functions are self-documenting.What is a Sub & Function Procedure in VBA
Let's say you have a function calculateLoanInterest and another that says connectToDatabase. Rules of naming Subroutines and Functions To use subroutines and functions, there are set of rules that one has to follow. A subroutine or function name cannot contain space A subroutine or function name should start with a letter or an underscore.
It cannot start with a number or a special character A subroutine or function name cannot be a keyword. A keyword is a word that has special meaning in VBA. Words like Private, Sub, Function, and End, etc. The compiler uses them for specific tasks. The keyword Private is used to specify the scope of the subroutine "ByVal arg1 As String, ByVal arg2 As String" : It declares two parameters of string data type name arg1 and arg2 "End Sub" "End Sub" is used to end the body of the subroutine The following subroutine accepts the first and last name and displays them in a message box.
Now we are going to program and execute this Sub Procedure. Let see this. How to call Subroutine in VBA Design the user interface and set the properties for the user controls. Add the subroutine Write the click event code for the command button that calls the subroutine Test the application Step 1 User Interface Design the user interface as shown in the image below Set the following properties.
It then passes the 'firstName' and 'lastName' variables as parameters. Step 3 Calling the subroutine from the command button click event. Right click on the command button as shown in the image below. Select View Code. The code editor will open Add the following code in code editor for the click event of btnDisplayFullName command button.
Step 4 Testing the code On the developer toolbar put the design mode 'off'. As shown below. Step 5 Click on the command button 'FullName Subroutine'. You will get the following results Download the above Excel Code Summary: A subroutine is a piece of code that performs a specific task. A subroutine does not return a value after execution Subroutines offer code reusability Subroutines help break down large chunks of code into small manageable code.
It is a combination of the Microsoft's event-driven VBA Arithmetic Operators are used to perform arithmetic operations such as adding, subtracting, VBA Comparison operators These are operators that are used to compare values.
So I have a whole bunch of things I can use this for cut down on redundancybut I want to know how I call into a sub like a button click procedure from a form. To call an event procedure, you should call a public procedure within the form, and call the event procedure within this public procedure.
If you want, you can actually bind the function to the form control's event without having to create an event procedure under the control. To do this, you first need a public function in the module instead of a sub, like this:.
Then, if you have a button on the form, instead of putting [Event Procedure] in the OnClick event of the property window, put this:. Most of the time, you can just call the sub like this:. Once you have a procedure, whether you created it or it is part of the Visual Basic language, you can use it. Using a procedure is also referred to as calling it. Before calling a procedure, you should first locate the section of code in which you want to use it. To call a simple procedure, type its name.
Here is an example:. Besides using the name of a procedure to call it, you can also precede it with the Call keyword. When calling a procedure, without or without the Call keyword, you can optionally type an opening and a closing parentheses on the right side of its name.
Like a variable access, the access to a procedure can be controlled by an access level. A procedure can be made private or public. To specify the access level of a procedure, precede it with the Private or the Public keyword. Private: If a procedure is made private, it can be called by other procedures of the same module.
Procedures of outside modules cannot access such a procedure. Public: A procedure created as public can be called by procedures of the same module and by procedures of other modules. Also, if a procedure was created as public, when you access the Macros dialog box, its name appears and you can run it from there. Learn more. Asked 10 years, 9 months ago.

I tried thisSuppose we have written a code somewhere in a workbooknow while writing another code we need the same code written earlier. So instead of writing the same code again, we can call that complete code or Sub procedure into the current Subcategory or Sub procedure. By this can avoid doing the same activity of workbook again and again. Watch our Demo Courses and Videos.
For this, we need a module. After that, we will get a blank page or window of Module. Now in that write a subcategory of code which we are performing or in any other name as shown below.
Now use a command of the message box and type any text or word you want to see in the message box. Now compile the code and run it by clicking on the Play button which is below the menu bar.
Now after the End in the same module, write another Subcategory or procedure in any name as shown below. In that again use the command MsgBox and give it message or text as per your choice. Here comes the function CALLwhich we will use to call both messages one by one. This will be used in the first subcategory. For this type Call in the first subcategory before Endfollowed by the name of that subcategory whose code we want to call. Hereafter MsgBox we are using Call followed by Arriving which is the subcategory name of the code written below.
Now compile the complete code from start to end and run it. Now click on Ok to proceed further. And if click on Ok again, then it will exit from the procedure. What if we change the position of Call function from before End to after the first Subcategory as shown below? Now let run the complete code again. For this, we need a new module. Open a Module from the Insert menu. And it gives a Subcategory in any name as shown below.
Long will allow us to consider any length of number. Now give Num1 and Num2 any number of your choice. We have given them and 50 respectively. Considering and 50 will help us to identify the output quickly. Now use multiplication formula to multiply the numbers stores in Num1 and Num2 and store their answer in Ans1 variable as shown below. In the next line of code, we will use the VBA Object. For this select the sheet with command Worksheet and give it a range of any cell.
We have selected the range cell as B1. And at last print the result with any name such as Result or Answer as shown below. Now give it the location where we want to see the answer in the same manner as shown above. Here we are choosing cell C1 as output cell and put the last variable Ans1 here.
To call both results one by one, use Call function it gives it the name of 2 nd Subcategory as shown below. Now compile the entire code and run. We will the first at cell C2, we got the result of the multiplication and at cell C3, a result of the addition. To know the proper sequence, we can use MsgBox command as used in Example-1 and see which values called at what sequence.Forums New posts Search forums.

Joined Jul 6, Messages Or is this even possible? For example, I have this sub here that calls subs from other modules but they are in the same project Some videos you may like. Excel Facts.

It is possible to call subs like sljpie has posted but you might encounter a few problems.
I'll check it out. Norie, Well, it really boils down to the fact that I can't use the code below, which deletes any row that has certain text in a certain column Even if I comment out all the "Dim" lines and place only one occurrence of them above the "Sub" line to avoid the "duplicate scope" error message. It still doesn't work. I know I can put this sub in its own module, and change the "Date Shipped" column for each sub, but I have to do this for around 15 different columns and don't want to have to create 15 separate modules for each one of these little subs.
It seems like a big waste of time and a poor way to code. What would really be great would be something like an array where I can change this line here Count, rngGrnd.
Calling Sub and Function procedures
The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. I would like to call a sub from another sub inside in the same module.
The first sub would be my main code and there I would call the second subroutine. Second subroutine receives multiple inputs as integer, double, double arrays and double matrices. The size of the arrays and matrices are known and stored in an integer variable. The sub also returns several outputs. So, I would like to do something like this. How does it know which sub is the main sub where it starts to run. Can I put the secondary sub on top and the code somehow starts from the bottom subroutine?
As the which runs first problem it's for you to decide, when you want to run a sub you can go to the macro list select the one you want to run and run it, you can also give it a key shortcut, therefore you will only have to press those keys to run it. Although, on secondary subs, I usually do it as Private sub CalculateA PS: If you have any other question just ask, but this isn't a community where you ask for code, you come here with a question or a code that isn't running and ask for help, not like you did "It would be great if you could write it in the Excel VBA format.
To the second one, protip: there is no main subroutine in VBA. Forget procedural, general-purpose languages. The term "macro" is only used for recorded user actions. This code is simple and do not provide powerful structures like loops, for example Do. VBA is a object based and event oriented language.
Call a function or sub procedure in VBA
Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.
If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets. It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.Forums New posts Search forums.

My question is this: what needs to be done for those variables that were stored in the original sub routine to be able to be used in the SecondSub that is called by the original?
