Hi all, I'm currently running an autorun.bat-file as suggested by Secret_Doom (see posting on 31 Oct). As for now, the .bat file looks like this: @echo off type nul> %temp%.\T1.DAT REGEDIT /E %temp%.\T1.DAT HKEY_CLASSES_ROOT\.PDF FIND "\" nul if not errorlevel=1 goto adobeOK start /w \AcroReader51_ENU.exe CLS EXIT :adobeOK del %temp%.\T1.DAT welcome.pdf CLS EXIT What the .bat-file does, is launching a certain .pdf-file (in this case welcome.pdf) when the cd is inserted. If the acrobat programm is not located, it automatically launches a setup-file from Acrobat Reader. As Secret_Doom said, the .pdf file doesn't launch itself on other OS's as Win XP. On Win NT the bat doesn't run at all. Not the .pdf OR the Acrobat-setup. I tried figuring out myself how to rewrite the .bat file so it would become compatible with Win 9x and Win NT, but the scripts i saw on the internet are a bit over my knowledge to generate it myself. Can i call upon the help of you guys again to help me out a bit with this? I thank you in advance, Frusti

Maybe to give a bit more info: This .bat-file is located in the root of a CD, and is launched by a autorun.ini-file. Both welcome.pdf and AcroReader51_ENU.exe are located in the root of the disc. If any other information is needed, i'd be delighted informing you. Delighted greetings, Frusti

First of all, that's not exately the script I suggested. The script in this subject is the right one (you had some posting problems and the line with the FIND cmd was changed, affecting the whole script. I've developed a batch file to do what you asked, Frusti. It's below.

You should replace those strings by the TAB character itself. For that, use NOTEPAD. Do NOT use EDIT.COM, because that program will add spaces, not the tab character itself. So, is that what you needed? Does it work on NT? -- Leonardo Pignataro - Secret_Doom -- PS: Don't waste your time trying to understand the batch script throughly, it is extremely complex and also involves debug / assembler concepts. I don't think I would understand it myself if it was written by someone else, not without comments. secret_doom@hotmail.com www.batch.hpg.com.br ____________________________________________________________________

Hey Secret_Doom, First of all i wanna thank you for having helped me out (AGAIN). You were right about the difficulty of the batchile...When i see what wrote up there, there's no way i could have fixed it myself, not even talking about understanding it heh. The only problem i'm still having is the tab-character. i tried to do the notepad-thing you suggested, but instead of a character i get the tab-space on my screen (as you also get with edit.com) So i'm currently trying to find out what character i should replace the string with... could you maybe past & copy it for me ? I will let you know for sure if the file worked on NT. So far i haven't been able to test it myself due to the little tab-character-problem, but again, i cannot thank you enough for having helped me through this. Delighted thanks, Frusti

Hello, Frusti. When you add the TAB character on NOTEPAD, it does really add the TAB character, not some spaces. Although, what you see is a long space, which could have been formed of some spaces (but it's not). However, if you pass the blinking cursor (the one which marks where you're writing) through that big space, you'll notice it will jump the whole space, won't walk one space at a time as if it was formed of some spaces. After copying and pasting the script, making the line ":eof" the last line (no blank lines before it) and exchanging the {TAB}'s, the file should be 2186 bytes long. Another tip which will help you to know if you've done it right: if you put spaces instead of the TAB char, even if .PDF files are recognized on your system, the script will act as if they weren't (so, it will try to run the adobe installation). I don't think copying-pasting the character would work. -- Leonardo Pignataro - Secret_Doom -- secret_doom@hotmail.com www.batch.hpg.com.br

Hey, forget what I said about the script size, that strangly depends on the OS you're viewing its size... Just put the TAB via NOTEPAD (works either on Win98 or on WinXP) and test the script, even if you see a big space (that's what you're supposed to see). If the script works on WinXP, it's because you've done it right. -- Leonardo Pignataro - Secret_Doom -- secret_doom@hotmail.com www.batch.hpg.com.br
