The Text property is used to set the text that will be displayed on the button. The TabIndex sets the index of Tab i. This is like setting TabOrder using Visual Studio control wizard. A TabIndex of 0 indicates that this control will be the first to gain focus when the Tab key is pressed. The Anchor is a very important property if you want to fix the location of a control with respect to some fixed point of the parent control or container.

For example in this case I want the Button to always stay anchored to the Bottom Right corner of the form no matter what. So if user tries to resize the form, the button will reposition itself to stay anchored to the Bottom Right corner of Form. The Location property sets the location of the control with respect to its parent control. The most important setting is how to handle the event when the user clicks on this control. This is done through adding an event handler to the Click event of the Control object.

We create a new event handler using the EventHandler object and pass the function that will handle the event, as an argument to the EventHandler constructor. The EventHandler created is added to the Click event of the Button. This way we can create controls dynamically and set their properties and event handling methods. After creating all the controls do not forget to add them to the parent container like Form , Panel , GroupBox , and etc. Like every Win32 control, we can customize the appearance and actions of all the controls.

Setting the AcceptButton property of the form can do this. The following code from the InitForm method shows some of the other properties that can be customized. Yes, you can do it. For this you need to import Win32 DLLs that implement the functions you need. This can be accomplished by using code as shown below.

This application shows the attribute for files. This means we need to do some File IO operations. We can create a File object by providing a file name as the parameter to constructor. Then we can make use of the Attributes property of the File Object to get the attributes of file. The attributes of the File are defined as a FileSystemAttributes enumeration object. For all the available enum values look in the documentation.

After that, we can do logical operations on the Attributes value to check if a particular file attribute is set or not. For example, to see if a file is of Archive type or not, the following code can be used. It is not a Boolean value. Therefore the resultant value is being compared against an enum value. There is one more gotcha in this operation. Archive , in bracket, the compiler will throw an error. Right now I do not know if it is a bug in the compiler or if that is the way it is intended, but for now put the logical operations in brackets.

To get file's creation date, use the CreateDate property of the File object. This will return a result in a DateObject. And then you can use the Format method of the DateTime object to get the string representation of the file's creation date.

Check the online documentation for the DateTime object to see what are the available format values. Yes, you can. Use Visual Studio to generate a resource script file. RC file. Add the resources you want to it. In this sample application, I have added an icon and a bitmap to the resource file.

Then use the command line RC compiler. This will generate a. RES file. For example in this application, WinFileInfo.
