validate username and disable menuitem

General
1

I have this code to check the system username. it works, the msgbox shows the correct username. But in my if statement, the check if UserName = “michael” does not work. Even the Test-MsgBox does not open. UserName is a property.

Whats my fault?

[code] dim sh as new Shell

if TargetWin32 then
sh.Execute(“echo %username%”)
ElseIf TargetMacOS then
sh.Execute(“whoami”)
end If

UserName = sh.Result

if UserName = “michael” then
MsgBox(“TEST”)
FilePreferences.Enabled = False
End If

MsgBox("Hallo " + UserName)[/code]

Regards,

Michael

The obvious question: when you debug this code, what is the value of ‘username’ at the conditional?

Have you tried whoami or echo %username% at the command prompt ?

Hi Michel,

well, the the msgbox at the end of this code show the correct username. so the app gets the username from the system.

sh.result has a trailing character, so username did not contain Michael, but Michael plus something else invisible.

This works :

UserName = Trim(sh.Result)

Thanks Michel, that works. The Test-MessageBox shows up. But for some reason, i am not able to disable the menuitem FilePreferences in the Applicationmenu. It is still accessible for the user.

[code] dim sh as new Shell

if TargetWin32 then
sh.Execute(“echo %username%”)
ElseIf TargetMacOS then
sh.Execute(“whoami”)
end If

UserName = Trim(sh.Result)

if UserName = “michael” then
MsgBox(“TEST”)
FilePreferences.Enabled = False
End If

MsgBox("Hallo " + UserName)[/code]

ok, i now use FilePreferences.AutoEnable = False instead of FilePreferences.Enabled = False. Now it Works.

[code] dim sh as new Shell

if TargetWin32 then
sh.Execute(“echo %username%”)
ElseIf TargetMacOS then
sh.Execute(“whoami”)
end If

UserName = Trim(sh.Result)

if UserName = “michael” then
MsgBox(“TEST”)
FilePreferences.AutoEnable = False
End If

MsgBox("Hallo " + UserName)[/code]

Thanks Michel and Roger for your help.

FilePreferences.AutoEnable = False FilePreferences.Enabled = False

You mean, both are necessary?

Yep.

11

ok, i use both in my code now.

Thanks.

On OS X you can use the API to get the username.

Declare Function NSUserName Lib "Foundation" () As CFStringRef Msgbox NSUserName

No shell required.

Hi Sam,

good to know, but i want to stay cross-plattform.

Thanks.

Sure;

#if targetMacOS then Declare Function NSUserName Lib "Foundation" () As CFStringRef Msgbox NSUserName #else ~ #endif

If there’s a current API for doing it, use the API!
