Finding whether its Design Mode or Runtime Mode in VB.NET

Sometimes, while creating controls, either by Inherited Controls or UserControls, we will be required to skip a piece of code depending upon the design time or runtime mode. This can be done easily by the following code inside a control.









If Me.Site IsNot Nothing AndAlso Me.Site.DesignMode = True Then
    'Designtime code here
Else
    'Runtime code here
End If


Using this code in a control, we can find the mode and avoid certain errors when in Design Mode. This is mostly used in overridden event methods in Inherited Controls.

Installation of rvm erroring out in Catalina - Ruby 2.3.x - How to solve them?

If you had recently updated your macOS to Catalina and then faced problem with installing certain versions of ruby because of random error, pls try the following.
If you are getting the following error, while doing a rvm install
Error running '__rvm_make -j8',
Try the following:
Possiblility is that because of openssl 1.1. OpenSSL 1.1 is not compatible with the ruby compilation during the rvm install.
First install openssl 1.0 using macports
$ sudo port install openssl10
Now install (reinstall) the ruby using rvm with openssl pointing to the macports version
$ PKG_CONFIG_PATH=/opt/local/lib/openssl-1.0/pkgconfig rvm reinstall 2.3.7 --with-openssl-lib=/opt/local/lib/openssl-1.0 --with-openssl-include=/opt/local/include/openssl-1.0
Just ensure that the openssl from macports is installed into /opt/local/lib/openssl-1.0
Hope this helps.
