Problem aborting page — NSIS Forum Archive

Hi all,

I have a page as below:

Page EnterCustom LeaveCustom

And the EnterCustom function:



Function EnterCustom 	

	File /oname=$PLUGINSDIR\installer.ini "@CMAKE_CURRENT_SOURCE_DIR@\installer\installer.ini"



	StrCpy $0 "$PLUGINSDIR\installer.ini"



	Call CreateDialogFromINI

FunctionEnd

The Installer.ini features a DirRequest as the 3rd field:



[Field 3]

Type=DirRequest

Left=10

Right=-10

Top=32

Bottom=44

Text=Select directory:

State=

And the LeaveCustom function:



Function LeaveCustome

	Call UpdateINIState

	

	ReadINIStr $Dir1 "$PLUGINSDIR\installer.ini" "Field 3" "State"

	

	FindFirst $0 $1 "$Dir1\*.jpg"

	StrCmp $1 "" 0 AllGood

	MessageBox MB_OK|MB_ICONEXCLAMATION "The directory is not valid. Please try again."

		Abort

	

	AllGood:



FunctionEnd

As you see, after the user provides a directory (either by manually typing it or by selecting it using the '...' button), the scripts checks to make sure there are JPG files available in that directory. If not, it will prompt the user to enter another/valid directory.

Now the problem: If the user enters a valid directory the first time, it all works great. But if the user enters something invalid, let's say "qwerty", the error message is shown and the Abort happens, but the $Dir1 variable always keeps the 'qwerty' value even if users enters some other data afterwards. So if after the error message user types 'lkjh' in that box, $Dir1 still reads 'qwerty'. Also, if at this stage user presses the '...' button and chooses a directory, not only $Dir1 stays 'qwerty', but also even the text box on the screen stays 'qwerty'.

Can you please tell me what I am doing wrong? Thanks.
