An example of using this function is shown below. In this case, if the workbook is already open then you inform the user that is must be closed for the macro to proceed. If you need to check if the workbook is open in another instance of Excel you can use the ReadOnly attribute of the workbook.
It will be set to true if it is open in another instance. You simply call the Close method of the workbook. Obviously, you cannot save changes to a workbook that is currently open as read-only. We have just seen that you can save a workbook when you close it. If you want to save it any other stage you can simply use the Save method.
The Workbook SaveAs method comes with twelve parameters which allow you to add a password, set the file as read-only and so on. You can see the details here. If the workbook is open you can use the two methods in the above section to create a copy i. SaveAs and SaveCopyAs. If you want to copy a workbook without opening it then you can use FileCopy as the following example demonstrates. The previous section shows you how to open a workbook with a given name.
Sometimes you may want the user to select the workbook. You can easily use the Windows File Dialog shown here. The Windows File Dialog. If you just want the user to select the file you can use the GetOpenFilename function.
The following function opens a workbook using the File Dialog. The function returns the full file name if a file was selected. If the user cancels it displays a message and returns an empty string.
When you call this function you have to check for the user cancelling the dialog. The following example shows you how to easily call the UserSelectWorkbook function and handle the case of the user cancelling. There is an easier way to access the current workbook than using Workbooks. You can use the keyword ThisWorkbook. It refers to the current workbook i. If our code is in a workbook call MyVBA. Using ThisWorkbook is more useful than using Workbooks. With ThisWorkbook we do not need to worry about the name of the file.
This gives us two advantages:. These may seem like very small advantages. The reality is your filenames will change all the time. Using ThisWorkbook means your code will still work fine. The following example shows two lines of code. One using ThisWorkbook and one using Workbooks. ActiveWorkbook refers to the workbook that is currently active. This is the one that the user last clicked on. This can seem useful at first.
The problem is that any workbook can become active by a simple mouse click. This means you could easily write data to the wrong workbook. Using ActiveWorkbook also makes the code hard to read. It may not be obvious from the code which workbook should be the active one. I hope I made it clear that you should avoid using ActiveWorkbook unless you really have to. If you must then be very careful. The following code shows examples of these ways. The reason for declaring a workbook variable is to make your code easier to read and understand.
It is easier to see the advantage of using an example. You can set a workbook variable with any of the access methods we have seen. In these examples the difference is not major. However, when you have a lot of code, using a variable is useful particularly for worksheet and ranges where the names tend to be long e. You can name the workbook variable to be something like wrkRead or wrkWrite.
Then at a glance you can see what this workbook is being used for. I miss that one when I translated the code from French to English. Maybe this weekend if I find some time I will try to try it. Maybe it is even better than the one presented here…. Please log in again. The login page will open in a new tab. After logging in you can close it and return to this page. Share this. Share 0.

Heading 2 Example. I received some e-mails from people asking me if it is possible to open a PDF file using Adobe Reader. See the VBA function below. Keep in mind that this function also works with Adobe Professional. However, the workaround for this problem is quite easy. The function will work again.

Member Since: October 5, Hi Astrit A workbook that contains macros will not execute those macros if it is opened in Excel Online. Hi Phil thanks for your information. VBA functions are built into Visual Basic for Applications, the scripting language that you use to create macros.
Worksheet functions are specific to Excel. Using worksheet functions saves you time over writing your own functions in VBA. Open the example workbook to follow along. It contains a list of product numbers and descriptions. The first two lines of the script are simple; they declare prodNum as an integer variable and prodDesc as a String variable, then assign the value in cell F2 to prodNum. You enter them similarly to how you would in Excel, but there are a few differences.
