When we need to enter a large amount of duplicate data in an Excel table, we often use the validity of the data to make a drop-down menu to increase the input speed of duplicate data. However, in the actual operation, you must select a cell that needs to enter duplicate data and click the Drop-down arrow to the right of the cell to see the Drop-down menu of the data validation that you have customized beforehand.

Note: If you need some kind of permission combination, such as permission to read and write access, and deny creation of access, you can do so by using an OR operation, as follows:

load them into an MDI application. To make them available, compile them as class libraries, and then add references to them in the configuration file.
Dynamically loading other types of classes
This technique can be used in addition to forms for other types of classes. However, the situation is relatively complex. In the previous example, the System.Windows.Forms.Form class interface was able to be bound early because we knew it was a form. Therefore, you can use the method of the form (for ex
Although. net assemblies are the best choice for new applications, you may at times need to employ COM objects instead. this walkthrough demonstrates two ways to create COM objects with Visual Basic. net: with and without the com class template.
