I'm trying to use AHK to write a dynamic bat file that will ultimately resize/rename images for me. I keep getting "Empty variable reference" errors around the area of FileAppend. What am I doing wrong?

Code:

#NoEnv  
SendMode Input  
SetWorkingDir %A_ScriptDir%  

FileSelectFile, SelectedFile, 3, , Open a file, Text Documents (*.ppt; *.pptx)
if SelectedFile =
    MsgBox, The user didn't select anything.
else
    FullFileName = %SelectedFile%
    SplitPath, FullFileName, name, dir, ext, name_no_ext, drive
   
   
FileAppend,
(
@echo off
set iview=C:\Program Files\IrfanView\i_view32\i_view32.exe
set ini=C:\path\to\ini\
set tini=C:\path\to\another\ini\
set source=%dir%\%name_no_ext%\
set target=%dir%\%name_no_ext%\
set oldtype=png
set newtype=gif
for %%a in ("%source%*.%oldtype%") do (
set oldname=%%~na
call :SUB
)

:SUB
set newname=%oldname:Slide=00%
"%iview%" "%source%%oldname%.%oldtype%" /ini="%ini%" /advancedbatch /convert="%target%%newname%.%newtype%" 
"%iview%" "%source%%oldname%.%oldtype%" /ini="%tini%" /advancedbatch /convert="%target%-t-%newname%.%newtype%" 

), C:\%dir%\%name_no_ext%\resize.txt

WHY?
there is nothing a BAT-file can do, that can´t be done by pure ahk.

"`%iview`%" "`%source`%`%oldname`%.`%oldtype`%" /ini="`%ini`%" /advancedbatch /convert="`%target`%`%newname`%.`%newtype`%"
"`%iview`%" "`%source`%`%oldname`%.`%oldtype`%" /ini="`%tini`%" /advancedbatch /convert="`%target`%-t-`%newname`%.`%newtype`%"

), C:\%dir%\%name_no_ext%\resize.txt

that should give the output i believe you wanted.

The two "%%" sections are what is causing you to get the empty variable error as ahk is seeing the %'s as the start and end of a variable reference. This is when you use the ahk delimiter "`" to tell ahk to treat them as literal %'s and not code. The "(" and ")" occurences also have to be delimited, else they could cause the fileappend to error and/or finish prematurely

Thanks, horntail.

Z_Gecko. I suppose I'm just showing my ignorance as to the power of AHK. The reason I was thinking it would be better to stack a series of dynamic batch scripts is because one bat won't start running until the other has completed.

The only way I know how to delay this occurrence in AHK is by using the Sleep function and I don't always know how much time it will take. Care to shed some light on a different way of doing things for me?

i´m not shure what you actually mean by that, but
maybe you just have not discovered RunWait yet.

stuboo: I think all you need is runwait. You should also search for GDI+ as tic has created some nice scripts which can do all sorts of things with image so you won't even need IrfanView. IrfanView is good and simple, but if you'd like to do as much as possible in "pure" AHK, look into GDI+.

Thanks, guys. You're right. RunWait is what I wanted to do, and I had actually seen/used it before but never really understood what the difference is between Run & RunWait.

Now that I have your attention

could you tell me what I might be doing wrong here?

Code:

title = This is my title
StringReplace, title, title, %A_SPACE%, -, All

RunWait, "C:\Program Files\s3copy\s3copy.exe" "%dir%\%name_no_ext%\/" bucket "%title%.zip" amazonAccessCode amazonSecretKey 

I'm using s3copy to upload a zip file to amazons simple storage service, but it doesn't seem to work when I use a variable for the filename instead of a static file name.

Is that / supposed to be there? Just quickly skimmed through code

take the "/" out, so its like this:

Code:

RunWait, "C:\Program Files\s3copy\s3copy.exe" "%dir%\%name_no_ext%\" bucket "%title%.zip" amazonAccessCode amazonSecretKey

Removed the / but it didn't fix the problem. Is there a way to stop the cmd window from closing so I can see the output?

Worked perfectly, PurloinedHeart. Thanks to everyone for the help. This community makes a great language even better.
