Restore Windows Bug in LibreOffice & OpenOffice

Published by:

I experienced the restore windows bug for several times when I try to open the Open Office or LibreOffice. Usually, my workaround is to remove the existing application and install the new one. I guess the root cause of the problem is I didn’t close each application separately before shutting down my laptop and causing this bug keeps occurring in my application.

When I try to open the application, this window will prompt out:

Restore Windows Bug
Neither “Don’t Restore Windows” button nor “Restore Windows” button is working. I cannot use the application to create new documents or view any documents properly. I tried to kill the process via Activity Monitor and it won’t solve the problem as it reappears again when I open the application next time.

Recently, I found the workaround to fix the problem. In Mac, search for the Terminal application and run this command to remove the savedState file:

rm -fr ~/Library/Saved\ Application\ State/org.libreoffice.script.savedState/

How to Run A Project with Command Line Arguments in MonoDevelop

Published by:

If you are writing a C# console application which involves of accepting user input from the command line parameter, the execution part will be slightly different in MonoDevelop. In Visual C++, you can access to the project’s /bin directory and just run the exe application with the parameter together using the command line. For example,

C:/Projects/testing/bin > sequence 6

The procedures will be different in Monodevelop installed on Mac OS X because the exe application will not work on Mac OS X. Due to this reason, you need to use the custom parameter to run the application. Here are the steps:
1. In MonoDevelop, click on Run > Run With > Custom Parameters
2. Browse the folder (/bin directory > Release) that stores the sequence.exe file and the location will be generated for the Working Directory. For example, 

/Users/mychin/Projects/sequence/sequence/bin/Release

3. For the ‘Arguments’ text box, you need to put the filename and the parameter which works as the input for the application. For example, sequence 6
4. Click the ‘Execute’ button and the output of the application will be displayed on the external command line window.

If you need more details about the configuration with the screenshots, you can refer to this page:  How to run a project with command line arguments (switches) after building in Monodevelop?
