VBA Code for Finding Column of Specific Value in Excel

Code Explanation

The provided code is written in VBA (Visual Basic for Applications), commonly used for automation in Excel. The code seeks to find a value in a specified row of an Excel worksheet and returns the column number of the first occurrence of that value.

Code Breakdown

lnCol = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="sds", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByColumns, SearchDirection:=xlNext, MatchCase:=False).Column

1. lnCol =:

   • This portion indicates that a variable named lnCol will store the result of the right-hand expression. The result represents the column number where the specified value is found.

2. Sheet1.Cells(lnRow, 1):

   • Sheet1 refers to a specific worksheet in the Excel file.
   • Cells(lnRow, 1) denotes a specific cell within that worksheet, identified by the row number lnRow and the first column (which is column A). The Cells property allows you to reference a cell dynamically based on its row and column numbers.

3. .EntireRow:

   • This method returns the entire row that contains the cell specified (i.e., the row in which lnRow resides), allowing the subsequent Find method to search across all cells in that row.

4. .Find(...):

   • The Find method is utilized to search within the specified range (in this case, the entire row). The parameters dictate the search criteria:
     • What:="sds": This specifies the value to be searched for in the row, which is "sds".
     • LookIn:=xlValues: This instructs Excel to search within the cell values (as opposed to formulas).
     • LookAt:=xlPart: This directs Excel to look for partial matches of the value (so "sds" can appear anywhere within a cell).
     • SearchOrder:=xlByColumns: This specifies the order of search; here, it will search column by column.
     • SearchDirection:=xlNext: This indicates that the search will proceed to the next cell that matches the criteria.
     • MatchCase:=False: This means that the search will be case-insensitive (i.e., "SDS" and "sds" will be treated the same).

5. .Column:

   • This retrieves the column number of the cell where the first occurrence of the specified value is found.

Key Concepts

• Variable Assignment: The result of the Find operation is stored in the variable lnCol, which can be used later in the code, such as in referencing columns dynamically in subsequent operations.

• Dynamic Cell Referencing: By using Cells(lnRow, 1), the code can operate on different rows by adjusting the value of lnRow, allowing for flexibility in data processing.

• Search Methods: The parameters used in the Find method enhance the robustness of the search, allowing for partial matching and controlling the direction of the search.

Additional Example

For further clarity, below is a similar example that demonstrates finding the first occurrence of the string "example" in the same row setting:

lnColExample = Sheet1.Cells(lnRow, 1).EntireRow.Find(What:="example", LookIn:=xlValues, LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlPrevious, MatchCase:=True).Column

• Difference in Parameters:
  • SearchOrder:=xlByRows: Changes the search to row by row.
  • SearchDirection:=xlPrevious: Searches in reverse order for finding the last occurrence.
  • MatchCase:=True: This time, the search will be case-sensitive.

Conclusion

The code snippet efficiently locates the position of a specific substring within a designated row, providing useful functionality for data manipulation in Excel. Understanding this code can facilitate more complex automation tasks, such as data validation and reporting.
