Hi, so far i have created a program that has a checkbox option 'dont show this again'. When i check the option, the window not displayed again all goes well here. But the problem is when i have uninstalled the application and reinstall it again, the checkbox option window is still not displayed. Plz help how can i make it to display on every reinstallation, here is link from which i created this application- Add a 'Dont show this dialog again' Checkbox with minimal effort[^]
I am using vs studio 2008 express and inno setup.

Solution 1

You have to delete the registry key which was generated in your dialog when you uninstall the program.
However, show us the code where you create the registry key when you want to know which registry key you have to delete.

Hi,

Create a configuration file and place a flag , based on the flag value enable or disable the dialog. When u check the checkbox update in the configuration file. and based on the value of in the configuration file do whatever you want.

Could be a way, but basing on what he said he already enabled the show/not show feature aöready. His only problem is now that he wants to have the show/not show thingies when the SW is reinstalled, without changing anything at the software.

There are plenty of solution are there, but this is the most easiest solution.

You can just call the

C#

Reset

function in your un-install. you can override the uninstall and call the "Reset" function. The reset function already having a logic to set the registry key values to 0. Or you can keep the code to remove the registry key in the Uninstall part. For this you can first call this

C#

GetRegKeyNameForForm

function which will get the RegistryKey and can remove by using this code

key.DeleteValue("DontShowAgain");
