Hi there!

I can't get my head around this one, maybe it's my english but I don't seem to be able to understand IF. I tried the following to show a gui depending on whether a file exists:

Code:
If FileExist("%A_AppData%\Folder\config.ini") = "%A_AppData%\Folder\config.ini"
{
IniRead, BrowseSource, %A_AppData%\Folder\config.ini, Sourcefolder, key
IniRead, BrowseDest, %A_AppData%\Folder\config.ini, Destinationfolder, key
MsgBox %BrowseSource%`t%BrowseDest%
Gui, Add, Text,, Do you want to backup your default folders?
Gui, Add, Button, , Yes
Gui, Add, Button, , No
Gui, Show
}
else
{
IfNotExist %A_AppData%\Folder
FileCreateDir, %A_AppData%\Folder
IfNotExist %A_AppData%\Folder\config.ini
FileAppend, , %A_AppData%\Folder\config.ini
Gui, Destroy
Gui, Add, Text,, Select the source folder:
Gui, Add, Edit, r1 w300 vSourceEdit,
Gui, Add, Button, gSource, Select
Gui, Add, Text,, Select the destination folder:
Gui, Add, Edit, r1 w300 vDestEdit,
Gui, Add, Button, gDest, Select
Gui, Add, Button, x+160, OK
Gui, Show, w320 h200
}
Return


Somehow when I run this and the ini file is already there it still shows me the Gui created after ELSE? I also tried setting the FileExist() = 1 thinking it would only return True or False (which I also tried)..

It's been a very long day, maybe I'll crack it tomorrow but suggestions are always welcome!

FileExist(FilePattern): Returns a blank value (empty string) if FilePattern does not exist (FilePattern is assumed to be in A_WorkingDir if an absolute path isn't specified). Otherwise, it returns the attribute string (a subset of "RASHNDOCT") of the first matching file or folder. If the file has no attributes (rare), "X" is returned.

   IniRead, BrowseSource, %A_AppData%\Folder\config.ini, Sourcefolder, key
   IniRead, BrowseDest, %A_AppData%\Folder\config.ini, Destinationfolder, key
   MsgBox %BrowseSource%`t%BrowseDest%
   Gui, Add, Text,, Do you want to backup your default folders?
   Gui, Add, Button, , Yes
   Gui, Add, Button, , No
   Gui, Show
} else {
   If (FileExist(A_AppData "\Folder\config.ini")!="D"){
      FileCreateDir, %A_AppData%\Folder
      FileAppend, , %A_AppData%\Folder\config.ini
   }
   Gui, Destroy

Thanks, I tried you code but it still shows me the second GUI created after ELSE ? I can't see what's going wrong?

If the code you are showing us is a subroutine that is part of a larger script then you are not destroying the GUI before you show it again,

i.e. the second part of the GUI adds those elements and then when it comes back around to GUI, SHOW in the first part it simply displays what has been built.

IF that is the case (pardon the pun) then do this: (maybe)

Code:
If (FileExist("%A_AppData%\Folder\config.ini") = A_AppData . "\Folder\config.ini"){
   IniRead, BrowseSource, %A_AppData%\Folder\config.ini, Sourcefolder, key
   IniRead, BrowseDest, %A_AppData%\Folder\config.ini, Destinationfolder, key
   MsgBox %BrowseSource%`t%BrowseDest%

   Gui, Destroy

   Gui, Add, Text,, Do you want to backup your default folders?
   Gui, Add, Button, , Yes
   Gui, Add, Button, , No
   Gui, Show
} else {
   If (FileExist(A_AppData "\Folder\config.ini")!="D"){
      FileCreateDir, %A_AppData%\Folder
      FileAppend, , %A_AppData%\Folder\config.ini
   }
   Gui, Destroy
   Gui, Add, Text,, Select the source folder:
   Gui, Add, Edit, r1 w300 vSourceEdit,
   Gui, Add, Button, gSource, Select
   Gui, Add, Text,, Select the destination folder:
   Gui, Add, Edit, r1 w300 vDestEdit,
   Gui, Add, Button, gDest, Select
   Gui, Add, Button, x+160, OK
   Gui, Show, w320 h200
}
Return


You also should just be using msgbox...

replace this

Code:
   Gui, Destroy
   Gui, Add, Text,, Do you want to backup your default folders?
   Gui, Add, Button, , Yes
   Gui, Add, Button, , No
   Gui, Show


with this

Code:
msgbox, 1,, Do you want to backup your default folders?


you can then use

Code:
IfMsgBox Yes
{
msgbox you pressed yes!
}
ELSE
{
msgbox you pressed no!
}

Etc

You are still not using the right syntax for FileExist()

using IfExist might be easier, e.g.
Code:
IfExist, %A_AppData%\Folder\config.ini

   IniRead, BrowseSource, %A_AppData%\Folder\config.ini, Sourcefolder, key
   IniRead, BrowseDest, %A_AppData%\Folder\config.ini, Destinationfolder, key
   MsgBox %BrowseSource%`t%BrowseDest%
   Gui, Add, Text,, Do you want to backup your default folders?
   Gui, Add, Button, , Yes
   Gui, Add, Button, , No
   Gui, Show
} else {
   If (FileExist(A_AppData "\Folder\config.ini")!="D"){
      FileCreateDir, %A_AppData%\Folder
      FileAppend, , %A_AppData%\Folder\config.ini
   }
   Gui, Destroy
   Gui, Add, Text,, Select the source folder:
   Gui, Add, Edit, r1 w300 vSourceEdit,
   Gui, Add, Button, gSource, Select
   Gui, Add, Text,, Select the destination folder:
   Gui, Add, Edit, r1 w300 vDestEdit,
   Gui, Add, Button, gDest, Select
   Gui, Add, Button, x+160, OK
   Gui, Show, w320 h200

Thanks! Always good to know how it should be used.. I solved it in the meantime by using the code below:

Code:
IfExist, %A_AppData%\Folder\config.ini
{
   Gui, Add, Text,, Do you want to backup your default folders?
   Gui, Add, Text,,
   Gui, Add, Button, Default, Yes
   Gui, Add, Button, x+70, No
   Gui, Show
}
ELSE
{
   Gui, Add, Text,, Select the source folder:
   Gui, Add, Edit, r1 w300 vSourceEdit,
   Gui, Add, Button, gSource, Select
   Gui, Add, Text,, Select the destination folder:
   Gui, Add, Edit, r1 w300 vDestEdit,
   Gui, Add, Button, gDest, Select
   Gui, Add, Button, x+160, Go
   Gui, Show, w320 h200
}
Return


The actual scripts are triggered by the buttons.. I tried something similair before but I must've typed it wrong..

Thanks everyone!
