Nice idea for a script and it has potential ... but...

Validation of numbers (for example, it will allow "text" as a valid height measurement)

if( isNaN(nFoo) ) nFoo = 0; //Failed, set to some default value or ignore the declaration

You don't need to multiply it with 1.
The next code will work just as good because the function isNaN() will already attempt to convert the variable to a number:

Javascript code:

---

var sFoo = "85.1";
if( isNaN(sFoo) ) nFoo = 0

---

In any case, whiz, check your code more carefully so you don't forget crucial stuff or make small mistakes. Although it wouldn't result in a wrong check (because of the above), you forgot to multiply the "EdtHeight" with 1 when you implemented the code posted by Matti:

code:

---

if (isNaN(objWnd.GetControlText("EdtWidth") * 1) == true || isNaN(objWnd.GetControlText("EdtHeight") * 1) == true)

---

So in this case you are lucky that you didn't needed the *1 at all, but in other cases such mistakes might result in hard to find bugs...
So, the above line can be written as:

code:

---

if (isNaN(objWnd.GetControlText("EdtWidth")) || isNaN(objWnd.GetControlText("EdtHeight")))

---

Also:
Remember to take the casing of strings into consideration when you compare strings. Code like:

Javascript code:

---

for( var i in WndLstId ) {
    if( WndLstId[i] == sTestId ) {        bIsUniqueId = false;
        break;
    }
}

---

...will fail if the Id of one control is "BtnTest" and the other control "Btntest".
You must convert the strings to the same casing (eg: lowercase) when comparing.

Even if the control id is case sensitive and using "BtnTest" for one control and "Btntest" for another is allowed, it is still a good idea to still dissallow it in your script because it is not recommended and not good practice and as a result such things _will_ eventually result in errors in the used scripts. So:

Javascript code:

---

if( WndLstId[i][b].toLowerCase() === sTestId.toLowerCase() ) {

---

PS: also notice the use of === (is identical) instead of == (is equal). Learn more about the difference here.

----

The above are all small details but can make a very big difference. So, a very big tip: before adding new stuff and/or features, revise your entire script very carefully as it contains many (small but crucial) errors and potential bugs, like vaccination already said.

Well, you're not implementing our sample code properly.
You shouldn't re-enable the control when one item in the loop doesn't match the ID to test simply because you won't have all used IDs matching that one ID, you have to check whether there is at least one match.

Javascript code:

---

        if (isNaN (objWnd.GetControlText("EdtLeft") * 1) == true || isNaN (objWnd.GetControlText("EdtDown") * 1) == true || isNaN (objWnd.GetControlText("EdtWidth") * 1) == true || isNaN (objWnd.GetControlText("EdtHeight")) == true)
        {
            Interop.Call("user32", "EnableWindow", objWnd.GetControlHandle("BtnAdd"), 0);
        }
        else
        {
            var bCanChange = true;            var sEdtId = objWnd.GetControlText("EdtId");            for (var X in WndLstId)
            {
                if (WndLstId.length > 1 && sEdtId == WndLstId[X] && X == WndLstTStSel)                    {
                        bCanChange = false;                        break;                    }
                }
            }
            Interop.Call("user32", "EnableWindow", objWnd.GetControlHandle("BtnChange"), bCanChange);        }

---

As you can see, you don't need an else-block anywhere, you simply check three things:

1. Check whether there are IDs in the array.
   
2. Check whether the currently chosen test ID matches the key name of the current item in the loop.
   
3. Check whether this item is currently being edited.

When these three conditions are fulfilled for one item in the loop, we can say that the chosen ID is not unique and thus bCanChange has to be set to false in order to disable the edit button.
When these conditions are never fulfilled, bCanChange will never change from its original value (true) and the button will be enabled.

I have sorted that problem out now, thanks!

Script fails to create xml files.

Line 70 =

JScript code:

---

else if (FileC(objWnd.GetControlText("EdtPath") + "\\" + objWnd.GetControlText("EdtName") + ".xml", true))

---

..FileC doesn't exist...

---

Ah, sorry.  I originally used a function for that, but I removed it.  I sorted that for the overwrite option, but not for the main writer.  Fixed!

Also, might want to read the corect folder from the registry, or at least use MsgPlus.ScriptFilesPath instead of just assuming it's "\Program Files\Plus!.." because it isn't always, for instance, on x64 machines.

There's a lot of other improvements you could make too, for instance instead of writing the xml to a text file and manually adding all the nodes with TextFile.WriteLine like you are, try using the XML DOM instead.

You should also include a preview feature to make the script actually useful, and should be relatively easy to add in.

Oh and you've used a few Plus! resources in your script - such as imgfind, imgsave, imgcode etc - and still included the files in the package, you could just call the resources directly from Plus!.

---

I know how to get the script's folder and registry path, but how can I get just the script base directory?

Applied to all validators.  Thanks for the tip! 

Looks interesting..
* roflmao456 tries it out

edit: neat

Thanks! 

Note to all: please post any bugs or errors you encounter! 

How about some screenshots.

Um...

I don't think you read my post correctly, you read the registry* to get the script folders path. [or alternatively, if you get the current script folder path from msgplus.scriptfilefolder then just use substr(-<whatever>) to minus the unnecessary part.]

*hklm\software\patchou\messenger plus! live\scriptsdir

----

Also, you're *still* packing plus resources in the script that you can just call from Plus!.

So can I use "MsgPlus.ScriptFilesPath", and then remove the "\Interface Writer"?

I have removed unnecessary images from the directory, and replaced them in the Windows.xml file with the Messenger Plus! image versions.  Some, like the add/delete button images, I have left as-is because they're from the Windows Live Messenger resource extraction - they look better.

Precisely. (Or a better way would be to just read the registry value IMO but whatever =p)

Then how do you do that?
