error driving me insane - but can't see what's wrong

[kingzooly]

Thanks look at post #5 I already found the fault, when the string was getting search it was always starting from 0 so when it found a duplicate IP it always had the same address and filled a table with that address (and got stuck in a loop), now I know what the problem is I can fix it easily. Thanks again though for your help as I appreciate it.

Not a problem, I would say use the debug tool but it always crashs on me so what I do these days is throw a dialog box in there testing easy part so I know its doing what I should glad you found it and I really glad you came back and explained witch part you found and fixed not many do that, hope your project success.

I know it will be a pain but have it do a dialog on each IP but add a count in the while so each time to adds one and make that the Dialogs title so you know its grabbing the IP's and finding them right lets see where its going wrong mabe that function does not return nil you see so try this maybe also fomate your code lol

MeCount = 0;

while( find1 ~= nil) do
	find1 = string.match(mystring, regex, nextposition);
	if find1 == nil then
		break
	else
		MeCount = MeCount +1;
		
		Dialog.Message("IP Found No:"..MeCount, "I found: "..find1, MB_OK, MB_ICONNONE, MB_DEFBUTTON1);
		
		result = Table.Count(target_table);
		if result >= 10 then
			Dialog.Message("Notice", "This page contains duplicate IP addresses\r\n" .. "Breaking out of a loop now\r\n" .. "Please check manually", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
			break
		else	
			strip()
		end
	end
end

Try that to see what you get on the 3ed loop like I said you might not return nil it might be "" or -1

If I change the while loop to this:

while( find1 ~= nil) do
	find1 = string.match(mystring, regex, nextposition)
	if find1 == nil then
		break
	else
	result = Table.Count(target_table);
	if result >= 10 then
	Dialog.Message("Notice", "This page contains duplicate IP addresses\r\n" .. "Breaking out of a loop now\r\n" .. "Please check manually", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
	break
	else	
	strip()
end
end
end

It breaks out once the table generated is equal or greater than 10 - If the search string doesn't contain identical IP's it put's them in the table until the table reaches 10 entries - if there is more than 1 identical address - every table entry is filled with that one IP.
That shows where my problem is

Thanks, if I change the strip function to this:

function strip()
   strip0 = String.Replace(find1, "<span>", "", false); -- remove <span> from the start of string
   strip1 = String.Replace(strip0, "</span>", "", false); -- remove </span> from the string so we are left with the IP
   result1 = String.Find(mystring, find1, 1, false); --get the start position of the IP
   nextposition = result1+1 --store the found address then add 1 so we can find the next ip address from this position   
   ---put check for dupe here:
   Dialog.Message("Notice", nextposition, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
   --end of check:  
   Table.Insert(target_table, Table.Count(target_table)+1, strip1); -- count the previous entries in our table then add our new string to the last entry.
end

and then the add a break in here:

while( find1 ~= nil) do
	find1 = string.match(mystring, regex, nextposition)
	if find1 == nil then
		break
	else
	strip()
	break
	end
end

I can see that if a there are more than 1 IP address found that is the same it always returns to the same address (this is causing the infinite loop), I need to somehow get if to store that first found address and then ignore it and move on, it works ok if the string it searches doesn't have matching IP's in the file, so it's nothing to do with the search pattern I'm using.

Cheers.

I think this part is stuck in an infinite loop:

while( find1 ~= nil)  --do a loop to check for more IP's
do
	find1 = string.match(mystring, regex, nextposition) --find the ip address in a string
if find1 == nil then
   break -- exit out of loop
   elseif find1 ~= nil then
   strip()
end
end

I think when it finds the duplicate IP it just keeps repeating -and reading that same IP over and over, but how would I put a check in here so it only reads once then continues to the next position in the file it's checking?

This While is a little clearner don't need to check if its not nil again if you already know it does not = nil in the first place.

while( find1 ~= nil) do
	find1 = string.match(mystring, regex, nextposition)
	if find1 == nil then
		break
	else
		strip()
	end
end

I would say try looking at the Patten again maybe, if you could post a example of what your doing when I have 2 mins I can see if it does it this end and see if I can make it work with my brain that I don't have much of lol

First note I can see here is that lua uses "Lua patterns" not regex so maybe you have to check that your patten is the corect format for lua, even it been the same ip shouldn't brake it.

One of the whiles/loops could be creating a lock up its the only thing that makes sense as there is no other code in there what's really hard on AMS

I have three files with the following values:

file 1 contains:
<span>192.168.100.1</span><br>
<span>192.168.100.2</span><br>

file 2 contains:
<span>192.168.100.1</span><br>
<span>192.168.100.1</span><br>

file 3 is just empty:

--try reading last Folder from Registry
LastFolder = Application.LoadValue("MultiThief", "LastFolder");
checkforfolder = Folder.DoesExist(LastFolder);

if checkforfolder == true then
--do nothing
elseif checkforfolder == false then
  LastFolder = _DesktopFolder;
end;

target_table = {};    --Creates a table whose values are empty
sections2 = {};    --Creates a table whose values are empty

webpage = Dialog.FileBrowse(true, "Locate File", LastFolder, "All Files (*.*)|*.*|", "", ".*", false, false);

if (webpage[1] == "CANCEL") then
Application.ExitScript();
--removehtml()
elseif (webpage[1] ~= "CANCEL") then
mystring = TextFile.ReadToString(webpage[1]);
--removehtml()
end

startposition = "0"

regex = "<span>" .. '[0-9+\.]+' .. "</span>"
	find1 = string.match(mystring, regex,startposition) --find the ip address in a string

function strip()
   strip0 = String.Replace(find1, "<span>", "", false); -- remove <span> from the start of string
   strip1 = String.Replace(strip0, "</span>", "", false); -- remove </span> from the string so we are left with the IP
   result1 = String.Find(mystring, find1, 1, false); --get the start position of the IP
   nextposition = result1+1 --store the found address then add 1 so we can find the next ip address from this position
   Table.Insert(target_table, Table.Count(target_table)+1, strip1); -- count the previous entries in our table then add our new string to the last entry.
end


if find1 == nil then
    Dialog.Message("Notice", "No IP addresses found", MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1); --prevent error message if no IP addresses were found
    Application.ExitScript(); --no point carrying on if no IP addresses are found.
    elseif find1 ~= nil then
    strip()
end


while( find1 ~= nil)  --do a loop to check for more IP's
do
	find1 = string.match(mystring, regex, nextposition) --find the ip address in a string
if find1 == nil then
   break -- exit out of loop
   elseif find1 ~= nil then
   strip()
end
end
--------------------------------------
--error above here
--------------------------------------

filename = "AutoPlay\\Docs\\Config\\reaper.ini"
sections2 = INIFile.GetSectionNames(filename);
filestart = "/files/"

table_values = Table.Concat(target_table, "\r\n", 1, TABLE_ALL);
choice = Dialog.Message("IP's Found - would you like to download", table_values, MB_YESNO, MB_ICONINFORMATION, MB_DEFBUTTON1);

then some unimportant code under that...


If file1 gets checked - I don't get any errors
If file3 gets checked - I don't get any errors

If file 2 gets checked - the app freezes with no errors, I know it's because both IP addresses found are the same but I don't know why it's freezing the app, does anyone have any idea? I have been at this for about 6 hours now and am no further forward that when I was when I begun.

Cheers.
