Command Prompt Install
Hello,
I am facing two problems with NSIS scripts. I am new on this but if someone could help me would be great...

I have to do a installer that runs from a command prompt. I have to set some parameter that the user needs to set (I have done that already), but if the user doesn´t pass the parameter the installer should show a message on command prompt usage: installer.exe -d <directory>

the other problem is that when I run the uninstall i have to zip the directory and save to a backup, I saw all the plugins but they just extract zip files they don´t create one...

can anyone help me?

To create Zip files you could include a copy of 7za.exe (7-zip.org) and extract and execute that (with ExecDos/nsExec). The executable is a little on the heavy side but I'm not sure if there are any other freely available command line zippers out there.

I have coded this several times for other people, try a forum search next time...

On XP and later it can be done perfectly: http://forums.winamp.com/showpost.ph...79&postcount=4

For older platforms, there is no AttachConsole so you would have to call AllocConsole instead on those systems

Hi guys,

I have done this way... thanks for the help :up:

                 StrCpy $R0 "$\r$\n $R0 $\r$\n"                
                 StrLen $R4 $R0          
                 System::Call "kernel32::AttachConsole(i -1)i .r0"
                 StrCmp $0 0 end                 
                 System::Call "kernel32::GetStdHandle(i -11)i .r0"
                 System::Call "*(i 0)i .r1"
                 System::Call "kernel32::WriteConsole(i r0, t R0, i R4, i r1, i 0)"
                 System::Free $1
                 System::Call "kernel32::FreeConsole()"                
                 end:

You should not use writeconsole to write plain ansi text, use WriteFile (If you use WriteFile, the output can be redirected and/or piped)

Hum ok...
I changed to
System::Call "kernel32::WriteFile(i r0, t R0, i R4, i r1, i 0)"

well I have another question Anders...

Is there a way to keep the prompt right after the command? like

c:\>example.exe -d d: <here comes the error message>

instead of what is doing now
c:\>example.exe -d d:
c:\> Error Message
