Qt IFW access file name of installer exe

Christoph Schaefer

I have an installer that contains a unique ID in its file name. For example, "my-installer-123456.exe". Is there a way to read the original file name during the installation?
I could not find anything in the Scripting API.

There is a predefined variable "InstallerFilePath" to solve my issue.

installer.value("InstallerFilePath");

During my search I came across other interesting solutions. For example, you can also list all running processes and then search for your own name via RegEx. Maybe this approach is also interesting for somebody.

// list the names of all running processes
var outputArr = installer.execute('cmd.exe', ['/C', 'wmic process get name']);
var id = "";
if(outputArr.length == 2) {
  // match the name of "my-installer-123456.exe" and extract the numerical id
  id = outputArr[0].match(/my\-installer\-(\d+)/i)[1];
}

This is merely a user forum and responses to IFW are rather scarce. With such a deep-inside question you might have better chances with the Qt developer's mailing list.
