## What it does
|
|
**VBA Code Description: Find Record Command**
|
|
|
|
### Overview
|
|
|
|
This VBA code snippet is used to execute a "Find Record" command in an Access database application. It allows users to search for specific records based on user input and provides feedback through error handling and automatic focus shifting.
|
|
|
|
### Step-by-Step Explanation
|
|
|
|
1. **Option Compare Database**: This line specifies that the comparison of strings should be case-insensitive, which is useful when searching for partial matches.
|
|
2. **Private Sub cmdFindPart_Click()**: This declares a private subroutine named `cmdFindPart_Click`, which will be triggered when a command button with the label "Find Part" is clicked.
|
|
3. **On Error GoTo Err_cmdFindPart_Click**: This line sets up error handling, specifying that if an error occurs within the subroutine, control should jump to the labeled block of code (`Err_cmdFindPart_Click`).
|
|
4. **s$ = txtSearch**: Retrieves the text from a search input field (`txtSearch`) and stores it in the variable `s$`.
|
|
5. **PartNumber.SetFocus**: Automatically focuses on a form or control named "PartNumber".
|
|
6. **DoCmd.FindRecord s$, acAnywhere, False, , True**: This line performs a find record operation in the current database table, searching for records that match the input string (`s$`) anywhere in the fields. The `acAnywhere` parameter indicates that the search should be performed anywhere in the field values. The other parameters (`False`, `, , True`) specify additional options, such as ignoring case and performing an exact match.
|
|
7. **Flag = "1"**: Sets a variable named `Flag` to the value `"1"`. This variable can be used elsewhere in the code to indicate that the find record operation was successful.
|
|
8. **txtSearch.SetFocus**: Automatically focuses on the search input field (`txtSearch`) after the find record operation completes.
|
|
9. **Exit_cmdFindPart_Click**: Exits the subroutine, allowing the program to continue executing.
|
|
|
|
### Error Handling Block
|
|
|
|
1. **Err_cmdFindPart_Click**: If an error occurs within the subroutine (i.e., `On Error GoTo Err_cmdFindPart_Click`), this labeled block of code is executed.
|
|
2. **MsgBox Err.Description**: Displays an error message box with a description of the error, retrieved from the `Err.Description` property.
|
|
3. **Resume Exit_cmdFindPart_Click**: Resumes execution at the next line of code after the error handling block, specifically the `Exit_cmdFindPart_Click` label.
|
|
|
|
### Best Practices and Security Considerations
|
|
|
|
* This code assumes that the search input field (`txtSearch`) is a text control, and the "PartNumber" form or control is also accessible within the application.
|
|
* The use of `On Error GoTo Err_cmdFindPart_Click` and `Resume Exit_cmdFindPart_Click` provides basic error handling, but may not be sufficient for all error scenarios. Additional error handling techniques, such as try-catch blocks, should be considered in more complex applications.
|
|
* The code does not perform any input validation or sanitization on the user-provided search string. This could potentially lead to security issues or unexpected behavior if malicious data is entered into the search field.
