CTL is Visual Basic UserControl Object File. The Microsoft Visual Studio software uses .CTL files as developer files. These files contain source code and properties for Visual Basic UserControls in plain text format. The corresponding .CTX files contain binary control data.
If your system is overloaded, it may not handle the program to open CTL files. Close other applications first. Ensure you have the latest drivers and updates installed. Outdated software may prevent using devices needed for CTL files.
CTL files contain ActiveX controls created in Visual Basic. Their content includes the controls and project output file. CTL files are created in Visual Basic for UserControl objects. The matching CTX files contain binary data.
CTL files can be viewed and edited in Visual Basic developer tools like Microsoft Visual Studio. These tools allow discovering and tracking the elements in CTL files. Visual Studio works for many programming languages, including Visual Basic.
dBASE programs can also open CTL files if Visual Studio does not work. Double-click a CTL file icon to open it, if your system has the right program associated with CTL files. Otherwise, install Visual Studio, which handles CTL developer files.
You can also use dedicated CTL file tools to open, view, edit, convert or compare CTL files without installing anything.
