Set color from a .txt file?

Hi,

I have a .txt file on my desktop which only contains 1 line of text:    #79a3d2

I also have the following code inside a .jsx file"

var fileToParse = File ('/Desktop/Photoshop.txt');
fileToParse.open('r');
var NewColor = fileToParse.readln();
fileToParse.close();
var color = app.foregroundColor;
color.RGBColor.hexValue=NewColor;
app.foregroundColor = color;

I am trying to change the foreground color to the hexadecimal code inside the text file, but I receive an error saying "Undefined is not an object"?

Can someone please tell me what is wrong with my code (in layman terms)?

Thank you all in advance.

Thanks - but that made no difference


var fileToParse = File (Folder.desktop + '/Photoshop.txt'); 

fileToParse.open('r'); 

var NewColor = fileToParse.readln(); 

fileToParse.close(); 

app.foregroundColor.rgb.hexValue=NewColor;

I do not know javaScript but hack at it.  I fine incasing code in try catch help me see what line the errors happen in and well placed alerts help  me see if things are going  right or wrong.

Thanks JJMack,

So........ looking at your screenshots - it seems that the txt file is being parsed correctly, but is not being assigned to the hexadecimal color value.

Also have no idea where the 000000 is coming from???

Now I have absolutely no idea how to correct it

The screen show was to show how to see what going on by adding alert messages the  first  message what was read. You can see I removed the # in the text file. If the file to parse statmemt was not fixes  there would have been no color read the color  message would be empty.

The second alert 000000 was what the current foreground color was.   that would have been a error statement if the .RGBColor was not corrected to .rgb

If a statement fails the Catch would tell you what the error was and what the line number of the bad code is.

This will take care of a problem.

var fileToParse = File (Folder.desktop + "/Photoshop.txt');

This modified code now produces a different error "Unterminated String Constant"??

var fileToParse = File (Folder.desktop + "/Photoshop.txt');
fileToParse.open('r');
var NewColor = fileToParse.readln();
fileToParse.close();
var color = app.foregroundColor;
color.RGBColor.hexValue=NewColor;
app.foregroundColor = color;

Lose the hash before the hex number.
