![]() ![]() On the Home page, click on the New → Pipeline dropdown menu, or click on the Orchestrate shortcut tile: There are several other ways to create a pipeline. So far, we have created a pipeline by using the Copy Data Tool. How do we create and organize them? What are their main properties? Can we edit them without using the graphical user interface? How do I create pipelines? In this post, we will go through pipelines in more detail. The Copy Data Tool created all the factory resources for us: pipelines, activities, datasets, and linked services. In the previous post, we used the Copy Data Tool to copy a file from our demo dataset to our data lake. SetupData.WriteToLogFile("Info\tPrevious installation not found\r\n", true) ĮndNow the Uninstall screen will appear, but only when installing to a previously-installed folder.Post 6 of 26 in Beginner's Guide to Azure Data Factory jump to next screen and don't display this one Local regvalue = Registry.GetValue(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\".sFoundKeyName, "UninstallString", true) Keys = Registry.GetKeyNames(HKEY_CURRENT_USER, "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall") check for per-user installation (added in Setup Factory 9.0.3.1) SetupData.WriteToLogFile("Info\tUninstall Argument: ".

Local regvalue = Registry.GetValue(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\".sFoundKeyName, "UninstallString", true)įor s in string.gfind(regvalue, '"( )"') do SetupData.WriteToLogFile("Info\tFound previous installation: ". If (String.Compare(String.Left(keyname, len), SessionVar.Expand("%UniqueRegKey%")) = 0) then Local len = String.Length(SessionVar.Expand("%UniqueRegKey%")) ![]() Local keys = Registry.GetKeyNames(HKEY_LOCAL_MACHINE, "Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall") SessionVar.Set("%UniqueRegKey%", SessionVar.Expand("%UniqueRegKey%")) SessionVar.Set("%UniqueRegKey%", Crypto.MD5DigestFromString(SessionVar.Expand("%UninstallerFolder%"))) Now each instance can be uninstalled individually. Placing this code on the "Ready to Install" screen allows you to add these Session Variables to the screen for debugging purposes and inspect their contents before actually deploying the files: ![]() Different folder name, different description, different key. To make sure that each instance gets its own registry key, avoiding that the entries are overwritten in the "Programs and Features" applet in the Control Panel, I simply use an MD5 checksum of the folder name where the uninstaller will be installed. The unique registry key does not need to be something readable, but it needs to be unique for each instance. SessionVar.Set("%UniqueRegKey%", Crypto.MD5DigestFromString(SessionVar.Expand("%UninstallerFolder%"))) The setting of the contents of %UninstallerFolder% should be obvious, as the files required for each uninstaller are placed into a sub folder of the installation folder (the %AppFolder%). I set this:Ĭode: SessionVar.Set("%UninstallerFolder%", SessionVar.Expand("%AppFolder%\\Uninstaller")) Also, each entry in the Control Panel needs to have a unique registry key, so an existing entry isn't overwritten, and that is why I use another custom Session Variable, named %UniqueRegKey%.īefore the deployment of the files starts, for example in the On Preload event script of the "Ready to Install" screen, the Session Variables need to be defined. Also, see this:Įach entry in the Control Panel will have its own description, using the name of the target folder to identify individually each instance which was installed. The content of this variable will be set at runtime, see below. Here, I define the location of the uninstaller with the aid of a custom Session Variable, named %UninstallerFolder%. For clarity, each entry in the "Programs and Features" applet should have a slightly different description, so you can select which one you wish to uninstall.Each uninstaller needs it own "Unique registry key", or the last installed entry will overwrite the previous one.Each installed instance of your files need its own copy of the uninstaller files (the executable, *.dat and *.xml, and possibly plugins and support files).If you wish to be able to install a product multiple times, into different folders on the same computer, and need to uninstall each of these instances individually and in any order, you need to follow this: ![]()
