Vba excel две строки

We have already gone over an introduction to string functions in our VBA Strings and Substrings Functions tutorial. We are now going to look at how to concatenate text strings.

Concatenate Strings

You can use the & operator in VBA to join text strings.

MsgBox "Merge" & "Text"

Concatenate Cells

You can also concatenate cells together. Below, we have the text strings in A1 and B1:

The following code shows you how to join text strings from cell A1 and B1 using the & operator,  in cell C1:

Range("C1").Value = Range("A1").Value & Range("B1").value

The result is:

Concatenate Variables

This is the full procedure to concatenate two cells together using string variables.

Sub ConcatenateStrings()

Dim StringOne as String
Dim StringTwo as String

StringOne = Range("A1").Value
StringTwo = Range("B1").Value 

Range("C1").Value = StringOne & StringTwo

End Sub

Using the & Operator with Spaces

When you want to include spaces you use & in conjunction with ” “. The following code shows you how you would include spaces:

Sub ConcatenatingStringsWithSpaces()

Dim StringOne As String
Dim StringTwo As String
Dim StringThree As String

StringOne = "This is"
StringTwo = "the text"
StringThree = StringOne & " " & StringTwo

MsgBox StringThree
End Sub

The MessageBox result is:

Using the & Operator to Concatenate a Quotation Mark

Let’s say your text string contains a quotation mark, the following code shows you how to include a quotation mark within a text string:

Sub ConcatenatingAQuotationMark()

Dim StringOne As String
Dim StringTwo As String
Dim StringThree As String

StringOne = "This is the quotation mark"
StringTwo = """"
StringThree = StringOne & " " & StringTwo

MsgBox StringThree

End Sub

The result is:

Putting Strings on a New line

Let’s say you have five text strings, you can put each text string on a new line or paragraph, using either the vbNewLine, vbCrLf, vbCr or Chr Function. The following code shows you how to put each text string on a new line:

Sub PuttingEachTextStringOnANewLine()

Dim StringOne As String
Dim StringTwo As String
Dim StringThree As String
Dim StringFour As String
Dim StringFive As String


StringOne = "This is the first string"
StringTwo = "This is the second string"
StringThree = "This is the third string"
StringFour = "This is the fourth string"
StringFive = "This is the fifth string"

MsgBox StringOne & vbNewLine & StringTwo & vbCrLf & StringThree & vbCr & StringFour & Chr(13) & StringFive

End Sub

The result is:

Excel VBA Concatenate Strings

Two or more substrings joining together to form a sentence or new strings are known as concatenation. We have seen concatenation in the worksheet either by using the ampersand operator or the addition operator. Even there is a separate function for concatenation in worksheet functions. But in VBA it is not that similar, in VBA there is no inbuilt function for concatenation of strings also neither can we use the worksheet functions for the same. The only method to concatenate strings in excel VBA is by using the & and + operator.

How to Concatenate Strings in VBA?

Below are the different examples to use the Concatenate Strings in Excel VBA.

You can download this VBA Concatenate Strings Excel Template here – VBA Concatenate Strings Excel Template

VBA Concatenate Strings – Example #1

First, let us begin with the most basic concept of using the & or known as ampersand keystroke used to concatenation in VBA. For this, follow the steps below:

Step 1: Insert a new module inside Visual Basic Editor (VBE). Click on Insert tab > select Module.

Step 2: Now we can begin with our subprocedure to show how to concatenate strings in VBA.

Code:

Sub Example1()

End Sub

Step 3: Now we need two string variables declared to show how concatenation is done.

Code:

Sub Example1()

Dim Str1, Str2 As String

End Sub

Step 4: Let us assign some random values to the variables.

Code:

Sub Example1()

Dim Str1, Str2 As String
Str1 = "Good"
Str2 = "Boy"

End Sub

Step 5: Now we can use the & or ampersand operator to concatenate both variables.

Code:

Sub Example1()

Dim Str1, Str2 As String
Str1 = "Good"
Str2 = "Boy"
MsgBox Str1 & Str2

End Sub

Step 6: Now when we execute the above code we can see the following result.

The strings are concatenated together but there is no space available because we didn’t provide it. So this is another lesson that we need to concatenate space too as space is also a character.

VBA Concatenate Strings – Example #2

In the above example we have seen how we concatenated strings also we know that we can use + or addition operator to concatenate strings, can we use concatenation on numbers using the addition operator? Let’s find out. For this, follow the steps below:

Step 1: In the same module let us start another subprocedure as shown below.

Code:

Sub Example2()

End Sub

Step 2: Declare two variables as an integer for the integer values.

Code:

Sub Example2()

Dim int1, int2 As Integer

End Sub

Step 3: Then assign some values to these integer variables.

Code:

Sub Example2()

Dim int1, int2 As Integer
int1 = 21
int2 = 23

End Sub

Step 4: Now let us use the addition operator for the concatenation.

Code:

Sub Example2()

Dim int1, int2 As Integer
int1 = 21
int2 = 23
MsgBox int1 + int2

End Sub

Step 5: If we execute the now we will not get the desired result.

Step 6: So, we cannot use the addition operator for concatenation when we use integers, we have to use the ampersand operator and also we need to provide a space.

Code:

Sub Example2()

Dim int1, int2 As Integer
int1 = 21
int2 = 23
MsgBox int1 & " " & int2

End Sub

Step 7: Now, let us execute the Code by pressing the F5 key or by clicking on the Play Button.

VBA Concatenate Strings – Example #3

So, we cannot use addition operators for integers but we can use them if we treat integer values as string. In this example, we will use integer values as strings. For this, follow the steps below:

Step 1: In the same module let us start with the third example.

Sub Example3()

End Sub

Step 2: Now declare two variables as String as shown below.

Code:

Sub Example3()

Dim Str1, Str2 As String

End Sub

Step 3: Now, assign integer values to the string variables in double quotation marks.

Code:

Sub Example3()

Dim Str1, Str2 As String
Str1 = "21"
Str2 = "23"

End Sub

Step 4: Now using the Msgbox function we will display both using the ampersand operator.

Code:

Sub Example3()

Dim Str1, Str2 As String
Str1 = "21"
Str2 = "23"
MsgBox Str1 & " " & Str2

End Sub

Step 5: Run the code by pressing the F5 key or by clicking on the Play Button.

VBA Concatenate Strings – Example #4

Now let us note that there may be some circumstances that we need to use the values from worksheets to concatenate. We have two separate values in the sheet as follows. For this, follow the steps below:

Step 1: So in the same module let us start another subprocedure for example 4.

Code:

Sub Example4()

End Sub

Step 2: Now declare three variables as Strings.

Code:

Sub Example4()

Dim Str1, Str2, Str3 As String

End Sub

Step 3: In the first three variables let us store the values from the worksheets.

Code:

Sub Example4()

Dim Str1, Str2, Str3 As String
Str1 = Range("A1").Value
Str2 = Range("B1").Value

End Sub

Step 4: Now we will use the addition operator for concatenation.

Code:

Sub Example4()

Dim Str1, Str2, Str3 As String
Str1 = Range("A1").Value
Str2 = Range("B1").Value
Str3 = Str1 + Str2

End Sub

Step 5: And we can put the new value in the other cell.

Code:

Sub Example4()

Dim Str1, Str2, Str3 As String
Str1 = Range("A1").Value
Str2 = Range("B1").Value
Str3 = Str1 + Str2
Range("C1").Value = Str3

End Sub

Step 6: When we execute the code we can see the result.

As explained above there is no inbuilt function for VBA to concatenate strings. Rather than the worksheet function, we use the & (ampersand) and + (addition) operators for it.

Things to Remember About VBA Concatenate Strings

There are few things which we need to remember about concatenate strings in VBA and they are as follows:

1. In the above four examples, we saw that there are two methods to concatenate strings in VBA.
Method 1: By using the ampersand (&) operator.
Method 2: By using the addition (+) operator.
2. We use ampersand and addition operator to concatenate strings in VBA.
3. There is no such function similar to the worksheet concatenate function in VBA.
4. Addition operators used on Integers will add the integers.
5. Space is also a character so between strings Space also needs to be concatenated.

Строковые операторы VBA и операторы сравнения

Операторы сравнения

Оператор	Синтаксис	Описание
=	A = B	Равенство: Если А равно В, то — True. Иначе — False
Если А меньше В, то — True. Иначе — False
Если А меньше или равно В, то — True. Иначе — False
>	A > B	Больше: Если А больше В, то — True. Иначе — False
>=	A >= B	Больше или равно: Если А больше или равно В, то — True. Иначе — False
<>	A <> B	Не равно: Если А не равно В, то — True. Иначе — False

Обычно операции сравнения используются в операторах организации циклов для принятия какого-либо решения о дальнейшем ходе выполнения операций.

Результатом любой операции сравнения является значение типа Boolean: True, False.

Если оба операнда в выражении сравнения имеют один и тот же тип данных, VBA выполняет простое сравнение для этого типа.

Если оба операнда в выражении сравнения имеют определенные типы и эти типы не являются совместимыми, VBA выдает сообщение об ошибке несовпадения типов.

Если один или оба операнда в выражении сравнения являются переменными типа Variant, VBA пытается преобразовать тип Variant в какой-либо совместимый тип.

Сравнение строк

При сравнении строк операторами отношения, VBA сравнивает каждую строку слева направо посимвольно.

В VBA одна строка равна другой только, когда обе строки содержат точно такие же символы в точно таком же порядке и обе строки имеют одну и ту же длину. Например, строки «абвгд» «абвгд » » абвгд» не равны между собой, т.к. VBA не игнорирует начальные или конечные символы пробела при сравнении строк.

Следует быть внимательным при сравнении строк переменной длины.

Двоичное и текстовое сравнение строк

Для сохранения текста компьютер использует схему, в которой каждый отображаемый символ имеет уникальный номер. Все буквы алфавита имеют свои уникальные номера. Обычно буквы верхнего регистра имеют меньшие номера, чем буквы нижнего регистра. Число, соответствующее определенной букве или символу, называется кодом символа.

При выполнении двоичного сравнения строковой информации VBA использует бинарный эквивалент числа для каждого символа. Такой метод сравнения называется двоичным или бинарным и является методом сравнения по умолчанию.

Т.к. буквы верхнего регистра имеют меньшие двоичные номера, буквы верхнего регистра располагаются в алфавитном порядке перед буквами нижнего регистра. Поэтому при двоичном сравнении строк, строка «АБВ» будем меньше строки «абв».

При текстовом сравнении строк VBA не использует двоичный эквивалент символов, и не «различает» верхнего и нижнего регистра. В текстовом сравнении строка «абв» равна строке «АБВ».

Для выбора метода сравнения строк используется директива Option Compare

Option Compare [Text | Binary]

Данная директива должна находиться в области объявления модуля.

Конкатенация строк

Присоединение одной строки к другой называется конкатенацией строк.

Конкатенацию строк обычно используют для формирования строк из различных источников в процедуре, чтобы создавать сообщение для вывода на экран. В VBA имеется два оператора для конкатенации строк.

Оператор конкатенации (&)

Оператор (&)в VBA используется только для конкатенации строк.

Операнд_1 & Операнд_2 [& Операнд_3..]

Операнд_N — любое допустимое строковое или численное выражение (которое преобразуется в строковое).

Тип данных результата конкатенации строк — String.

Если операнд в выражении конкатенации строк имеет значение Empty или Null, VBA интерпретирует этот операнд как строку нулевой длины (строка не содержащая символов).

Обратите внимание! Символ (&) операции конкатенации обязательно необходимо отделять пробелом от имени переменной, т.к. в противном случае VBA может интерпретировать этот символ как символ определения типа Long.

Оператор сложения в конкатенации строк

Для конкатенации строк можно также использовать оператор (+).

Этот оператор имеет такой же синтаксис и требования, как и оператор (&). Однако следует понимать, что в VBA основное предназначение оператора (+) — это арифметическое сложение. Поэтому, чтобы избежать двусмысленности чтения программного кода, для конкатенации строк настоятельно рекомендуется использовать именно оператор (&).

Приоритеты выполнения операций

Многие из выражений в программной коде являются сложными (составными), т.е. состоят из двух или более выражений.

При вычислении сложных выражений VBA следует следующим правилам:

• Части выражения, заключенные в круглые скобки, всегда вычисляются в первую очередь;
• Конкретные операции выполняются в зависимости от иерархии операторов (таблица ниже);
• При равенстве иерархии операторов, они вычисляются слева направо.

Оператор	Комментарии
^	Возведение в степень, высший приоритет
—	Унарный минус
* /	Умножение и деление имеют равные приоритеты
MOD
+ —	Сложение и вычитание имеют равные приоритеты
&	Конкатенация строк выполняется после арифметических операций перед операциями сравнения и логическими операциями
= ><>	Все операции сравнения имеют равные приоритеты и выполняются слева направо. Для группирования операций надо пользоваться круглыми скобками
NOT
AND
OR
XOR
EQV
IMP

How can I concatenate strings in VBA?

This question comes from a comment under Range.Formula= in VBA throws a strange error.

I wrote that program by trial-and-error so I naturally tried + to concatenate strings.

But is & more correct than + for concatenating strings?

3 Answers 3

& is always evaluated in a string context, while + may not concatenate if one of the operands is no string:

This is simply a subtle source of potential bugs and therefore should be avoided. & always means «string concatenation», even if its arguments are non-strings:

The main (very interesting) difference for me is that:
«string» & Null -> «string»
while
«string» + Null -> Null

But that’s probably more useful in database apps like Access.

There is the concatenate function. For example But the & operator always concatenates strings. + often will work, but if there is a number in one of the cells, it won’t work as expected.
