Scheduled Tasks - How to create some with if & else?
Hello

I'm trying to implement some Scheduled Tasks.

These are for backups, and link to .bat scripts.

There are two kind of Batch scripts in-use;[list=1][*]One that backs-up data to the I:\ drive[*]One that backs up data to the N:\ drive[/list=1]
I'll include both scripts within the one NSIS installer. All servers have an I:\ drive, however only about half of them have the N:\ drive. Here is an idiosyncratic-programming way of showing you what I'd like;

If N:\ exists, extract nDrive-Script.bat to the Backup-Scripts directory

else extract iDrive-Script.bat to the Backup-Scripts directory.

Can you please give me an example script which;

Extracts the batch files based on existing directories
Installs them as Scheduled Tasks which run at a certain specified time & date

Thanks in advance,

Panarchy

BTW: Backup-Scripts folder is located in T:\Backup-Scripts

To check if the drive exist, you can use IfFileExists, or ${If} ${FileExists} with the LogicLib header.
For scheduled tasks:

I have written some code, below which SHOULD do the first part (everything but install the new Scheduled Tasks).

I can't get the aforementioned code to compile correctly. :(

Here is the output of the compiler;

Please help me fix the script.

Thanks in advance,

Err... The compiler is already telling you what is wrong.
'Error: could not resolve label "PastIBackupsCheck" in function ".onInit"'

You tell it to go to a label that doesn't exist.

Problem solved!
Thanks, I found a better example online, and it is now this;

Function .onInit
IfFileExists "I:\Backups" 0 continue
                MessageBox MB_YESNO|MB_ICONQUESTION "Does I:\Backups exist?" IDYES true IDNO continue
true:
!macro ExtractiBackupScripts ToDir
    SetOutPath `${ToDir}`
        File "Contig.exe"
        File "Defrag.cmd"
        File "NTBackup.cmd"
   !macroend
!insertmacro ExtractiBackupScripts "T:\Backup-Scripts\"

continue:
   !macro ExtractnBackupScripts ToDir
    SetOutPath `${ToDir}`
        File "Contig.exe"
        File "NTBackup-2009.cmd"
   !macroend
!insertmacro ExtractnBackupScripts "T:\Backup-Scripts\"

FunctionEnd

Which seems to work fine... however I'd like to remove the prompt, and make it continue automatically based on existence of the drive letter/directory.

Also I'll need to add the Scheduled Tasks... which from the looks of things is very confusing. Hopefully I won't have to end up with "ExecWait"ing a Batch!!!

Please tell me how I can fix up my function.

Thanks in advance,

Panarchy

EDIT;

Might of fixed it with:

Section /o "N:\Backups detected" nBackups_detected
nBackupsExists:
  SectionGetFlags "${nBackups_detected}" $0
  IntOp $0 $0 | ${SF_SELECTED}
  SectionSetFlags "${nBackups_detected}" $0
MessageBox MB_OK nBackups
   !macro ExtractnBackupscripts ToDir
    SetOutPath `${ToDir}`
        File "Contig.exe"
        File "Defrag.cmd"
        File "NTBackup.cmd"
   !macroend
!insertmacro ExtractnBackupscripts "T:\Backup-Scripts"

PastnBackupsCheck:
   !macro ExtractiBackupScripts ToDir
    SetOutPath `${ToDir}`
        File "Contig.exe"
        File "NTBackup-2009.cmd"
   !macroend
!insertmacro ExtractiBackupScripts "T:\Backup-Scripts\c"

SectionEnd

EDIT2: Ended up fixing the issue, now just need to work out how to add Scheduled Tasks...

They ended up not wanting it, so I've got a half-finished script here. Works perfectly, however doesn't install any Scheduled Tasks.

Enjoy ;)
