What is ASCX file?

The ASCX file has been categorized as Web Files. It was designed by Microsoft. Additionally, the Web Files category contains 303 of other files. ASP.NET User Control Format appears on 2 operating systems as a functional file. The file will work on Mac OS, Windows systems, unfortunately not on others. The Adobe Dreamweaver application is recommended to open the file. It was released by Adobe Systems Incorporated. There are also 7 alternative programs to handle the ASCX file. You can use Mozilla Firefox, Google Chrome, Microsoft Visual Studio, Microsoft Internet Explorer in case Adobe Dreamweaver cannot be used.

How to open ASCX file?

The most common problem when using ASP.NET User Control Format is that a specific ASCX is not associated with the program. This is manifested by the fact that ASCX files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the ASCX file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Adobe Dreamweaver

In this case, you should first verify that the Adobe Dreamweaver application is installed on the computer. The easiest method is to use the system search engine by entering the program name Adobe Dreamweaver in it. In the absence of an appropriate program, its installation in the vast majority of cases will fix the problem. Below is a list of programs that support the file ASCX.

Step 2. Create association of Adobe Dreamweaver with ASCX files

However, it may happen that the application itself does not cause the ASCX file to open in the Adobe Dreamweaver application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the ASCX file with the Adobe Dreamweaver program.

Step 3. Update Adobe Dreamweaver to the latest version

If, however, after binding Adobe Dreamweaver with ASP.NET User Control Format there were still problems, you should update the program to the latest version. This can be done using the application (if it provides such options) or from the Adobe Systems Incorporated website and install the latest version.

Step 4. Check for the following problems with the ASCX file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

The affected file may be 0 KB or smaller than expected. Usually this applies to ASCX files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the ASCX file that we want to open. Sometimes virus-infected ASCX files cannot be recovered, so make a backup in advance.
Older version of ASCX file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the option of recovering data from damaged ASCX files. You can restore the file from a backup or use Microsoft help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ASCX except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. Copying the ASCX file to another location will fix the problem.
This problem usually affects more complex files. In this case, the ASCX file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes it is necessary to wait a while before referencing the ASCX file again. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If nothing helps, please reset the device.
