CLT File - opening and understanding

What is a CLT file?

Files that contain the .clt file extension are most commonly associated with the Visual Basic application development software.

The CLT files that are created with this software contain an ActiveX control that has been created with the Visual Basic program, saving the control in a plain text format. The ActiveX controls can then be downloaded and executed by the user's Internet browser.

The CLT files that are created by Visual Basic contain the source code and the properties for the ActiveX control.

The dBASE IV Aldus software program has also been known to use the .clt file suffix. These CLT files contain setup control files that are referenced by the dBASE software.
