Private Values Commands

Last modified: May 6, 2025

Introduction

The commands in this group are related to showing and deleting private values.

Studio Pro stores private values, such as values for private constants, in an encrypted way in the user’s local app data. These private values are defined by:

  • The path of the .mpr file of the app
  • The version of Studio Pro
  • A key, such as StudioPro.Settings.Configuration.ConstantValue.MyFirstModule.MyConstant for the configured constant value for constant MyFirstModule.MyConstant

Make sure to exit all instances of Studio Pro before using these commands, as Studio Pro keeps a cache of private values.

mx show-private-values Command

The mx show-private-values command produces a list of paths, versions, and keys of all private values stored in the current user’s local app data. It does not show the (encrypted) value.

Usage

Use the following command pattern: mx show-private-values

The tool will output one line for each private value, with the path, version, and key, separated by the tab character.

Examples

The output might look something like this:

C:\Users\John.Doe\Mendix\MyProductApp\MyProductApp-main.mpr 10.12.0 StudioPro.Settings.Configuration.ConstantValue.MyFirstModule.MyConstant
C:\Users\John.Doe\Mendix\MyProductApp\MyProductApp-main.mpr 10.18.0 StudioPro.Settings.Configuration.ConstantValue.MyFirstModule.MyConstant
C:\Users\John.Doe\Mendix\MyBikesApp\MyBikesApp-main.mpr 10.12.0 StudioPro.Settings.Configuration.ConstantValue.MyFirstModule.OtherConstant

Return Codes

These are the return codes:

Return Code Description
0 The command ran successfully.

mx delete-private-values Command

The mx delete-private-values command deletes private values from the current user’s local app data.

When used with -f (--force), it deletes private values and displays the number of private values it has deleted. When used with -n (--dry-run), it shows which private values would be deleted, but does not actually delete anything.

When you delete a private value that is needed by an app, the next time you open that app in Studio Pro, it will produce a consistency error indicating that you have to type the value again.

Usage

Use the following command pattern: mx delete-private-values [-n|-f] [OPTIONS]

These are the required parameters:

Option Shortcut Result
--dry-run -n Shows which private values would be deleted, but does not actually delete anything.
--force -f Deletes private values.

Either -n or -f must be specified.

These are the OPTIONS:

When used without options, the command deletes all private values. The options filter the list of private values to be deleted.

Option Result
--not-on-disk Deletes only private values whose path cannot be found on disk.
--path Deletes only private values for the given path.
--version Deletes only private values of the given Studio Pro version.
--key Deletes only private values with the given key.
--item Specifies the path, version, and key, separated by whitespace, of a specific private value to be deleted.

Examples

Example Result
mx delete-private-values -n Shows all private values, but does not delete them (Same as mx show-private-values).
mx delete-private-values -f --not-on-disk Deletes all private values for which the path cannot be found on disk. This is useful when you have deleted one or more apps from your disk.
mx delete-private-values -f --path="C:\Users\John.Doe\Mendix\MyBikesApp\MyBikesApp-main.mpr" --version=10.12.0 Deletes private values that were stored for the app MyBikesApp-main.mpr for Studio Pro version 10.12.0. This is useful after you have upgraded that app to a later version.
mx delete-private-values -f --version=10.12.0 Deletes private values for Studio Pro version 10.21.0. This is useful after you have upgraded all your apps to later versions.
mx delete-private-values -f --item="C:\Users\John.Doe\Mendix\MyProductApp\MyProductApp-main.mpr 10.12.0 StudioPro.Settings.Configuration.ConstantValue.MyFirstModule.MyConstant" Deletes a specific private value (Same as specifying --path=, version= and key=).

Return Codes

These are the return codes:

Return Code Description
