There are endless ways yo accomplish this. The most simplistic would be to store a value in the registry and check it when you start the app and update it when you close it. If you are worried about the user being able to change it, you can store that value in a more difficult to find registry key or make it a calculated value or encrypt it.

Look up SaveSetting and GetSetting in VBHelp

using SaveSetting and GetSetting (and using the registry at all) is an option, but easily changed, unless you use a setting that only you can interpet, or the string is actually encrypted.
The API functions CryptEncrypt and CryptDecrypt will help you with this.

Make a reference to Registry Access Functions.
Use the:
UpdateKey and GetKeyValue to get and set your values
GetKeyValue HKEY_LOCAL_MACHINE,REG_KEY "\MyKey", "MyString",MyVariable
MyKey and MyString can be whatever you want to name them.
If you want to go deeper in the Key structure use: \MyKey\MyKeyOne\MyKeyTwo"
MyString is the string value namethat will hold the data.
When using GetKeyValue "Myvariable" will hold the requested value.
When using UpdateKey "Myvariable" will be the value you are updating
