If you use nsDialogs to create the custom page, you can use the onChange function to go to an NSIS function every time something is changed in the textbox. In that function, simply get the text out of the textbox and compare it with "".

Littlepot, You could use something like this:

PHP Code:


			
${If} $variable == ""

GetDlgItem $6 $HWNDPARENT 1   

EnableWindow $6 0 ; disable 

${Else}

GetDlgItem $6 $HWNDPARENT 1   

EnableWindow $6 1 ; enable

${EndIf}
