NSH | Shell made for a Systems Programming course in Fall | Command Line Interface library

Here don’t understand why if you only select MyApp it does not allow the user to select the directory. For each of the programs, the MUI_PAGE_DIRECTORY macro is where it indicates that the user should select the directory, which the SelectFilesMyApp clearly has, so I am not sure why yet if the user only selects that program it doesn’t allow them to pick a custom directory. If they select all the programs, then the user can select a custom director for each of the MyPartnerApp Plugin, MyApp, and LicenseManager programs.

Here is the full script, which is partly based on https://nsis.sourceforge.io/Two_installations_in_one_installer:

I’m running an efi application from the startup.nsh in efi shell. How can I get a value as return of the application to the shell and use it in the shell script?

I got an Alexa device and I’m using an esp8266 to get request from the echo dot. I can wake on lan my Pc but it’s not enough. I have windows and Linux on my Pc so I thought “I need some code to run before boot so I can communicate with my esp8266 to know witch os should be booted”. So I started searching everywhere to find a solution and I think I’m really close to it. What I did was to put the efi-shell as main boot, let it execute the startup.nsh. In this startup.nsh I want to start my efi application who can communicate with the esp8266. Is this the right way to do this thing? Should I do something else? The problem is that I can’t code this app. I can’t understand how to use protocols and which protocols are the solutions. The application should send a simple character to the esp to let it know that the computer is ready to get boot instruction. The esp should reply “1” for windows or “2” for Linux. Can someone give me some advices for this task? Is it the right way or am I doing a lot of useless stuff? Maybe exists a better way

I want to develop an application to be automatically executed from startup.nsh in EFI shell. This application should send raw bytes to an ip address and receive some back. I looked everywhere for explanation and example for the implementation of simple network protocol in my code but found nothin. Can someone explain and show a code example using gnu_efi libaries?

I have created simplest electron app from official Quick Start Guide.
I am able to create installer also using electron-builder

Now I want to try customUnInstall macro of NSIS option given at https://www.electron.build/configuration/nsis

My installer.nsh file is

In order to create a signed uninstaller, I cannot create this using the usual NSIS WriteUninstaller command, because the usually script will create the uninstaller and embed it inside the installer, so there is no chance to sign the uninstaller. For details please see https://nsis-dev.github.io/NSIS-Forums/html/t-245688.html.

This means that I would have to create a separate uninstaller script, sign that, and then embed it in the installer using a normal File command. This works in deleting the files; however, since the uninstaller executable that is running, it cannot delete itself, and leaves the uninstaller.exe and the MyApp directory behind. Here is my uninstaller script:

Please note that I initially created an installer for two applications based on https://nsis.sourceforge.io/Two_installations_in_one_installer where the first application is the main one while the second application is the license manager. That said, I did remove the nested checkboxes with only one layer of checkboxes. FYI, I have also been referencing this article: https://www.codeproject.com/Articles/24187/Creating-an-Installer?msg=5782957#xx5782957xx

The issue that I am having is that when I run the installer, all of the files from MyApp and FlexLM are installed in the $PROGRAMFILES64\${PRODUCT_NAME} folder and in the C:\${FLEX_DIR}. So when I am installing two applications, it looks like both SEC1 and SEC3 are executed for the MyApp installation and both SEC1 and SEC3 are executed for the FlexLM installation:

The issue that I am having is that when I get to the second license manager app, where I click to browse for a custom folder, and create a new custom folder, when I press OK on the browse it then returns with this custom folder but then appends the application name after that. So for example when I return from the browse for custom directory dialog, it would not return with, say:

I am trying to create a page with L-shaped grids. I got the layout down by creating 2 x 2 grids and each grid uses a 0 width div as a spacer to push another floated div to void out the space where I don't want text to appear. I am having a problem now trying to be able to scroll the text and adjust the position of the floated void div by adjusting the height of the spacer div.
