How to get text box output via installoptions

[automateyourbiz]

Hi,
I'm adding an option to my installer for the user to enter a license key, and the installer than posts some details to my server and download an encrypted license file. I've got this latter part working OK when I hard-code the initial license key.

The area I'm having problems is getting the user input.

Here's my code:

code:


# Ask for license registration details

Function CheckLicenseShow

         !insertmacro MUI_HEADER_TEXT "Enter License Key" "Enter the license key mailed to you when you purchased the software."

         !insertmacro MUI_INSTALLOPTIONS_DISPLAY "CheckLicenseShow"



FunctionEnd



## Validate license

Function CheckLicenseLeave

         !insertmacro MUI_INSTALLOPTIONS_READ $R0 "getlicense.ini" "Field 1" "State"

         

         StrCmp $R0 '' GotLicense NoLicense

         Abort

     NoLicense:

         ; Box is checked, so enable the next button:

         MessageBox MB_OK "Please enter your license key"

         Abort

     GotLicense:

         ; Get the license

         MessageBox MB_OK "Got license: $R0"

     Exit:

         ; user pressed 'next' so exit!



!insertmacro MUI_HEADER_TEXT "Getting License File" "Please wait whilst your license key is verified and the license file downloaded."



; Code to download license file goes here

FunctionEnd

When I don't enter a license key,and just press "Next", I get no message box, and do NOT go to the next page.

If I do enter a license key, I get "Got License: " in the pop-up box, no actual key. And then I DO go onto the next page.

Any ideas why $R0 is not populated with the contents of the text box.

Also, I've set up the ini file as follows:

code:


; Ini file generated by the HM NIS Edit IO designer.

[Settings]

NumFields=2



[Field 1]

Type=Text

Left=113

Right=236

Top=16

Bottom=28

MinLen=1

Flags=WANTRETURN

ValidateText=Please enter your license key.



[Field 2]

Type=Label

Text=Insert your license key from your emailed purchase receipt

Left=8

Right=112

Top=14

Bottom=33

But I don't even get the "Please enter your license key" validation text.

Any ideas?

StrCmp $R0 '' GotLicense NoLicense ->

StrCmp $R0 '' NoLicense GotLicense

Also remove the exit: label while you're not actually use it.

Thanks Red Wine.
That helped, but I still couldn't get the value. However, a few hours later I've gotten there.

I was calling the .ini as

code:


Function .onInit

         !insertmacro MUI_INSTALLOPTIONS_EXTRACT_AS "getlicense.ini" "CheckLicenseShow"

FunctionEnd

And then had

code:


Function CheckLicenseShow

         !insertmacro MUI_HEADER_TEXT "Enter License Key" "Enter the license key mailed to you when you purchased the software."

         !insertmacro MUI_INSTALLOPTIONS_DISPLAY "getlicense.ini"



FunctionEnd

Some confusion over the CheckLicenseShow I think.

I now have

code:
Function .onInit

         !insertmacro MUI_INSTALLOPTIONS_EXTRACT "getlicense.ini"

FunctionEnd

and

code:


Function CheckLicenseShow

         !insertmacro MUI_HEADER_TEXT "Enter License Key" "Enter the license key mailed to you when you purchased the software."

         !insertmacro MUI_INSTALLOPTIONS_DISPLAY "getlicense.ini"



FunctionEnd

and it works perfectly.
