How to access session custom action data (properties) during install and uninstall in Wix? -

-

Can you please tell me what is wrong with the following code? I am able to access custom action data during installs and I add my value custom action collection session. However, during the uninstallation, I added the price pairs to the collection. 

  Public category custom action {// This action is only called app install [custom action] during the public stable operation. CreateToolbar CreateToolbar (session session) {// This works fine; wix scripts are sent appropriately from // / Expected Value string toolbar name = session ["VSTOCustomAction_ToolbarName"]; // Save the value for the Uninstaller session. CustomActionData.Add ("VSTOCustomAction_ToolbarName", Toolbar name); ...} // This action is only called during the application uninstall [custom action] Public Static Action Routal DotToolbar (session session) {// Get the toolbar name and remove it // Why does the following call return empty? String toolbarname = session. Custom section data ["VSTOCustomAction_ToolbarName"]; ...}} is the WIX part below which calls the above custom action. - Include VSTO custom actions - & gt; & Lt; Binary ID = "VSTOCustomAction" sourcefile = "CustomAction.CA.dll" /> & Lt; Custom Action ID = "CreateToolbar" BinaryKey = "VSTOCustomAction" DllEntry = "CreateToolbar" Execute = "Instant" /> & lt; Custom Action ID = "RemoveToolbar" BinaryKey = "VSTOCustomAction" DllEntry = "RemoveToolbar" Execute = "Instant" /> ... & lt; Custom Action ID = "PropertyAssignin.org name" property = "VSTOCustomAction_ToolbarName" value = "muteuburnname" /> ... & lt ;! - Modify the install sequence to call our custom action - & gt; & Lt; InstallExecuteSequence & gt; & Lt; Custom Action = "PropertyAssignLoginName" = Before "CreateToolbar" & gt; & Lt ;! [CDATA [(& ToolbarComponent = 3) No more! (ToolbarComponent = 3)]] & gt; & Lt; / Custom & gt; & Lt; Custom action = "CreateToolbar" = "InstallFinalize" followed by & gt; & Lt ;! [CDATA [(& ToolbarComponent = 3) and No (! ToolbarComponent = 3)]] & gt; & Lt; / Custom & gt; & Lt; Custom Action = "RemoveToolbar" = "InstallFinalize" & gt; & Lt ;! [CDATA [(& ToolbarComponent = 2) and No (! ToolbarComponent = 2)]] & gt; & Lt; / Custom & gt; & Lt; / InstallExecuteSequence & gt;

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
