My program sets its display based on if the program is running for the first time or not. In order to determine if the program is running for the first time I am currently using a
//this boolean exists within my programs settings
Setting boolean FirstRun = True;
When the program runs it calls a method that checks the state of that bool value and acts accordingly:
if(Properties.Settings.FirstRun == true)
{ lblGreetings.Text = "Welcome New User";
//Change the value since the program has run once now
Properties.Settings.FirstRun = false;
Properties.Settings.Save(); }
else
{ lblGreetings.Text = "Welcome Back User"; }
It seems to work pretty effectively, however if the .exe file is moved and launched from a new location it considers it a first run, and I'm concerned that I'm doing this in a messy fashion and perhaps there exists a more efficient manner to test for the programs first run. Is there a better way to do this?
Seems that your problem is actually that if you move executable
to another location/folder on the same pc, it loses somehow the information about the fact that it was already run at least once.
Using UserSettings
, on Properties.Settings.Default.FirstRun
should resolve your problem.
Something like this, a pseudocode :
if(Properties.Settings.Default.FirstRun == true)
{ lblGreetings.Text = "Welcome New User";
//Change the value since the program has run once now
Properties.Settings.Default.FirstRun = false;
Properties.Settings.Default.Save(); }
else
{ lblGreetings.Text = "Welcome Back User"; }
Look on this sample how to achieve that in more detailed way.
Since your question appears to be concerned about each user that launches the application, then you should design a per-user solution.
Using Properties.Settings will actually work and be efficient as long as the setting in question is user-specific.
However, if this is not desired or appropriate for your application, you could also write a user-specific entry to the registry.
For example:
const string REGISTRY_KEY = @"HKEY_CURRENT_USER\MyApplication";
const string REGISTY_VALUE = "FirstRun";
if (Convert.ToInt32(Microsoft.Win32.Registry.GetValue(REGISTRY_KEY, REGISTY_VALUE, 0)) == 0)
{
lblGreetings.Text = "Welcome New User";
//Change the value since the program has run once now
Microsoft.Win32.Registry.SetValue(REGISTRY_KEY, REGISTY_VALUE, 1, Microsoft.Win32.RegistryValueKind.DWord);
}
else
{
lblGreetings.Text = "Welcome Back User";
}
Hard to guess what is messy if you don't post or describe it. An obvious approach is to have a setting named "ExePath". If you get null or a string that doesn't match Assembly.GetEntryAssembly().Location then it got either just installed or moved.
