This guide covers step by step with pictures how to create a desktop shortcut which you can click and be directly taken onto the server, without having to manually open the SAMP server list and press on connect. It's simple and anyone should be able to follow the guide along. I will base this on a windows system, but it is doable with other OS'es as well. I will however assume you know what you are doing then, so images shouldn't be required.
If anything is unclear, or it doesn't work - view the video at the very bottom of this post![/legend]
Locate the file path of your samp.exe. You can do this easily by right-clicking on your samp.exe desktop icon, clicking on "Properties" then copy the line of text out of the "Target" field. It will look something like "C:\Program Files (x86)\Rockstar Games\GTA San Andreas\samp.exe" although this may vary. The important part is that it ends with "samp.exe".
Open notepad or another text editor and paste the line of text you just copied. At the end of the text line (After the quotation mark), make a single space then type the server's adress and the port (server.redcountyrp.com:7777 as of now).
It should look something like following when you are done:
"C:\Program Files (x86)\Rockstar Games\GTA San Andreas\samp.exe" server.redcountyrp.com:7777
Right click on your desktop, mouse over "New" then click on "Shortcut". A window will appear. In the empty box, copy and paste the new and edited file path. Hit Next and give the shortcut an appropriate name, then click on Finish.
Paste the file path you've edited into the box circled in red below. Hit "Next", enter a name as prompted and then click on "Finish" to create the shortcut.
