The excel Format cells dialog we looked at earlier is a modal UserForm. So are the Excel Colors and Name Manager dialogs. Modal versus Modeless The actual code to make a UserForm modal or modeless is very simple. Show vbModal ' Show as modeless - code does not wait frm.
Item String - broken in v1. Faster name resolution for single props. Background Have you ever wanted to find out generic properties about a file, such as the duration length of an MP3 file, or the date a JPEG picture file was taken on a digital camera?
Windows Explorer shows us this sort of information, so surely we can tap into this facility to programmatically access these "properties"? Note that I use the term "property" rather generically.
Some information that Windows Explorer provides is calculated - e. Windows Explorer properties can also originate from the filesystem, such as the shared status of the file. Fortunately, Windows does provide mechanisms for obtaining these detailed properties directly from the Operating System.
Unfortunately, the low-level interfaces that are defined to access these properties are not VB-friendly they don't support the IDispatch interface and therefore need an external typelibrary reference at a minimum, or preferably a small DLL written in a lower level language.
As Sascha Trowitzsch points out later in the comments of this article, there is a type library already defined for helping scripting languages access some of these properties, although I have to say that the options are more limited than the solution I'm going to provide here.
Some of you reading this will be familiar with my article on Disabling the Mouse Wheel in Access Forms and know that I provided a convenient solution to including native machine code into a small VBA module which doesn't require any external references.
Hopefully you can you see where this is heading I have done the same here in that the sample database file contains native machine code inside a VBA code module in order to avoid you needing to distribute an extra DLL or typelibrary file with your application should you choose to use this code.
Check out her ListFiles Database that makes use of this code. To show your appreciation, and to enable us to spend more time writing solutions like this, please consider donating a small amount through PayPal: Overview of each class FilePropertyExplorer class is the root class.
It is a self-instantiated class that contains the native machine code used throughout. FileProperties are an enumerable collection of all the available properties for that file.
If you want to support writing to property values, you must open the file with the WriteSupport parameter set to True. This indirectly causes the property set to be more restricted in terms of enumeration in that you can then only enumerate direct properties of the file for example, you won't get properties about the shared status of the file.
Write-support is only applicable when run on Windows Vista or newer - in older systems, this is ignored. When the file is opened with write-support, the file is locked until the FileProperties object is released.
You do not need to declare a variable of type FilePropertyExplorer in your code. See the examples below and in the provided database. ID Property Get Count As Long Returns the count of properties defined in the collection This collection class supports the use of For-Each enumeration -- see examples in the following section.
FileProperty is an item class and supports the following methods; Property Get Name As String Returns the system identity name of the property.
This is safe to use as an identity field even on non-English systems. A handful of properties do not have a name assigned and the only method of referencing them is by the ID property.
It consists of a GUID identifying the property schema followed by an integer identifying the property index in the schema. This can be an array for multi-value type properties.Time honored and tested, this is the basic form of the message box. This form is something that anyone who has written more than 5 lines of VBA code is familiar with.
We can export the data from Microsoft Excel to Microsoft Access by using VBA. Below is the VBA code and process which you need to paste in the code module of the file. For more information about working with VBA, select Developer Reference in the drop-down list next to Search and enter one or more terms in the search box.
This example shows various ways to use the InputBox function to prompt the user to enter a value. In VBA, MsgBox function is used for displaying a dialog box with a predefined message. It returns an integer value based on the button clicked by the user, this .
Our First Button. Open a new document and select the Developer tab. Then go to the Insert control and place a button on your document. This will pop up the “Assign Macro” dialog, just click on the “Add” button, which will bring up the VBA editor.
In Access databases you can use the MessageBox macro action to display a message box containing a warning or an informational message.
