Condition question

[Dynaletik]

I am going to use WPI for a multiboot DVD. My question: How does the conditional statement work? I forgot it / don't know it.

As an example, what would I have to put in for the Creative SB Audigy Control panel, if the file ctaud2k.sys in system32 folder must exist for install???

[Dynaletik]

There must be someone who knows how to handle the condition statements. What about hasi? I didn't hear anything from him for a quite long time now...is he working or on holiday?

Add this line:

cond[pn]=['FileExists("%SystemRoot%\\System32\\ctaud2k.sys")']

If that file doesn't exist, the option to select it in wpi will not appear. You can combine multiple tests into one with && (and) and || (or). (dunno about the 'or', havn't tested it, but it should work

Thank you man....I only need one per program.

cond[pn]=['FileExists("%SystemRoot%\\System32\\ctaud2k.sys")']

This works if condition is true (enable if exist), but what if the condition is false. Another word, if exist do not enabled option. Can this be done?

Thanks

I think just putting a ! in front of the Fileexist will do it (aka negation in programming):

cond[pn]=['!FileExists("%SystemRoot%\\System32\\ctaud2k.sys")']

[singk]

cond[pn]=['!FileExists("%SystemRoot%\\System32\\ctaud2k.sys")']

Thanks. It works great.....

If that file doesn't exist, the option to select it in wpi will not appear.

Is there any way or how do I modify the boxes.js so that the option appears, but Dimmed out/lock the checkbox instead?

Eventhough the condition is false, I still want it to display the option, but enable to check it so I can tell which applications had installed. If we make it disappears, then we wouldn't know what's available on the CD or what had or had not installed.

NOTE: I have little knownledge of Javascript

Thanks

I could do that, but it's 00:15 and I'm tired... Maybe when I have some spare time

One part to modify is this:

for (i=1; (prog[i]!=null); i++) // for defined programs do ...
	{     
  // We only display things that pass condition tests, unless we are in debug mode.
  //
  if(cond[i] && cond[i][0]) {
 	 var c = unescape(replpath(cond[i][0]).replace(/\\/g, "\\\\"));
 	 try {
    if(!eval(c)) {
   	 debug("Condition failed: " + c + " -- not rendering " + prog[i], 1);
   	 continue;
    }
 	 } catch(e) {
    alert("Error in condition statement for " + prog[i] + ":\n\n" + cond[i] + "\n\nTreating as a false condition.");
    continue;
 	 }
  }

and some parts after it. But now SLEEP
