Reading value from Config file to textbox

[pkonduru]

Hi All,

I have a Custom Dialog that has a few ports that the user must enter. I have some default values in them. If there a config file existing in the install directory, the ports must auto populate on the custom dialog. I have all the pieces of the code in place. I just wanted to know if there is a cleaner way of doing it. I am pasting excerpts for just one of the port. Will need to duplicate this code for the other ports also.

1)In my main nsi I have this. $PortNumber is a global variable. I grab the value of the port.

IfFileExists $INSTDIR\conf\tomcat.properties 0 pastFilecheck
MessageBox MB_OK "found the properties file"
${ConfigRead} "$INSTDIR\conf\my.properties" "port.shutdown=" $R1
MessageBox MB_OK "Port number is: $R1"
StrCpy $PortNumber $R1
pastFilecheck:

2)In my custom dialog .nsh file I have this. Check if port value exists or load the default value.

${If} $PortNumber == ''
StrCpy $PortNumber '9954'
MessageBox MB_OK "New port number is :$PortNumber"
${NSD_SetText} $hCtl_FoundationDialog_TextBox1 $PortNumber

${EndIf}
; === TextBox1 (type: Text) ===
${NSD_CreateText} 127.7u 37.54u 111.24u 12.31u "$PortNumber"
Pop $hCtl_FoundationDialog_TextBox1
