Install Options: Prompt for variable

Please Help! 🙂 I'm relatively new to NSIS site. I've searched the Forums and InstallOptions documentation to no avail.

Trying to prompt the user for the name of a remote computer
then use that "CompName" to build a path.

I' ve looked thru InstallOptions and can't figure it out.
I get that I need an INI file, that's fine... it's the instructions on how to get the custom page to display that are messing me up.

Can anyone provide some sample scripts? (not the same in NSIS documentation)

Here's what i'm trying to do...

Text box to type in ComputerName (example: SCC40234)
Hit NEXT
the users input is pasted into a path like:
\\SCC40234\c$\Windows\System32
and then 2 files are copied over.

DONE

Like I said, the examples in InstallOptions are confusing me, I've been trying to write this script for a week and get nothing but errors.

PLEAZ help! 😢

In the INI file:

[Settings]

NumFields=1



[Field 1]

Type=text

Value=

State=Default Computer Name

Left=

Right=

Top=

Bottom=

In installer script:

Page Custom Pre Post

...

Function Pre

  ; init dialog

  Pop $R0 ; hwnd to window

  ; show dialog

FunctionEnd



Function Post

  ReadINIStr $R1 <ini file> "Field 1" "State"

  ; $R1 has the value of the computer name entered by user

FunctionEnd

I get a blank screen with a progress bar which has "Install" and "Cancel" buttons..but nothing else on it.
If I hit Install.. then I can see that it is trying to copy the files from the path but it's missing the $R1 string so of course the copy fails.

The custom page doesn't show up on the screen therefore NSID never pauses on the Custom page so the user can input the field
Here's my entire code.. I'm keeping it simple for right now, 'til I figure out what I'm doing wrong.....

Outfile Mapi.exe



Function .onInit



  InitPluginsDir

  File /oname=c:\mapi.ini mapi.ini



FunctionEnd





Page Custom Pre Post





Function Pre

  ; init dialog

  Pop $R0 ; hwnd to window

  ; show dialog

InstallOptions::dialog c:\mapi.ini

FunctionEnd



Function Post

  ReadINIStr $R1 mapi.ini "Field 1" "State"

  ; $R1 has the value of the computer name entered by user

FunctionEnd



Page instfiles



Section Copy

 CopyFiles $SYSDIR\mapi.dll \\$R1\C$\windows\system32\mapi.dll

 CopyFiles $SYSDIR\mapisrvr.exe \\$R1\c$\windows\system32\mapisrvr.exe

SectionEnd

I guess I just don't understand How the custom page system works.

Try doing:

...

Page Custom Pre Post

Page instfiles

...

Function .onInit

  InitPluginsDir

  SetOutPath "$PLUGINSDIR"

  File "mapi.ini"

FunctionEnd

...

Function Pre

  InstallOptions::dialog "$PLUGINSDIR\mapi.ini"

FunctionEnd

Function Post

  ; R1 should have the company name entered

  ReadINIStr $R1 "$PLUGINSDIR\mapi.ini" "Field 1" "State"

...

OK.. I incoporated the code and NOW I get a dialog box..
I used

Right=-1
Top=0
Bottom=12


BUT...
the

ReadINIStr $R1 "$PLUGINSDIR\mapi.ini" "Field 1" "State"

Doesn't return the value of Field1

If I use MessageBox MB_OK "$R1" all I get is "Success"

If I refer to $R1 in a file path I get...
Copy to \\success\C$\windows\system32\mapi.dll
Copy failed

So I've made progress, I just can't tell why it is registering the field as "sucess" and not the actual value?

InstallOptions says this...

To get the input of the user, read the State value of a Field using ReadINIStr:

ReadINIStr $R0 "$PLUGINSDIR\test.ini" "Field 1" "State"

But obviosuly it's not that simple..there's something else to it..???

Make sure you use ReadINIStr in the leave function not the creation function.

Thanks Afrow 🙂

after using Create and Leave
and then removing an extra POP command

it's working fine now

Thanks Goldy1604 for your quick responses as well.
Sometimes I get such a quick response on these forums it's almost like Instant messaging. 🙂
