Hello,

While I was working on my Last.fm for Messenger Plus! Live I realized that I wasn't able to display an image from an internet location in a window. Maybe it's possible, but I don't know how... anyone?

Thanks in advance,
Yorick

First you should download the file to a temporany location, which you can do with the new MsgPlus.DownloadFile function. Then, you can use PlusWnd.ImageElmt_SetImageFile to change the image displayed. Don't forget to delete your file afterwards!

code:

---

pPlusWnd.ImgElmt_SetImageFile('myimage', '\\C:\\Temp\\myimage.jpg');

Thanks a lot guys!

Almost worked it out now, but I still have a bit of a problem.
I have the following code:

code:

---

WndProfileInformation = MsgPlus.CreateWnd('WndProfileInformation.xml', 'WndProfileInformation');

if(MsgPlus.DownloadFile(avatar))
{
    Debug.Trace('[Download] Started');
}
else
{
    Debug.Trace('[Download] Failed');
}

---

code:

---

function OnEvent_DownloadFileComplete(Url, OutFile, Success)
{
    if(Succes)
    {
        WndProfileInformation.ImgElmt_SetImageFile('ImgDisplayPic', OutFile);
        var File = new ActiveXObject("Scripting.FileSystemObject");
        File.DeleteFile(OutFile);
    }
}

---

Each and every variable in a script needs to be declared somewhere. This is done using the var statement.

eg:

code:

---

var MyVar = "Hello World";

---

code:

---

function DoSomething() {
    var MyLocalVar = "Hello World"
}

---

code:

---

var MyGlobalVar = "Hello World"

function DoSomething() {
    //blahblah
}

---

At the top of the script I have

code:

---

var WndProfileInformation;

---

code:

---

WndProfileInformation.ImgElmt_SetImageFile('ImgDisplayPic', OutFile);

---

code:

---

function OnEvent_DownloadFileComplete(Url, OutFile, Success)
{
    if(Success)
    {
        Debug.Trace('File: ' + OutFile);
        WndProfileInformation.ImageElmt_SetImageFile('ImgDisplayPic', OutFile);
    }
}

I don't know if I need to open a new topic about this, please say if I need to!

I bumped into another problem. I want to show some information, but I don't always have all the information....

Like this:
Profile:
Name
Country (optional)
Age (Optional)

But sometimes I don't have information to fill the country, and I do have information to fill the age. If I do it with static controls, you'll get a gap, because I can't fill country.. anyone a brilliant idea how to do this?

---

The difference here is the missing "var" prefix, without it it'll get declared as a global variable.

Note: when the window is destroyed, you should delete the variable too!

hint: always provide enough details from the start

PS: a control is in that context always static... no control moves around on their own. Static means 'user can not interact with it' (eg: a text label), opposed to dynamic which is changeable by the user (eg: a combobox). Thus it doesn't have anything todo with moving.

code:

---

var Name = "John";
var Country = "";
var Age = "25";
var ShoeSize = "5";
var Fingers = "10"
var State = "Married";

var Profile  = ""; // String to display in first and only label control

If (Name !== "") Profile += "\n" + Name;
If (Country !== "") Profile += "\n" + Country;
if (Age !== "") Profile += "\n" + Age + (Age == 1 ? " year" : " years");
if (ShoeSize !== "") Profile += "\n" + ShoeSize;
if (Fingers !== "") Profile += "\n" + Fingers;
if (Sate !== "") Profile += "\n" + State;

// Remove first NewLine character
Profile = Profile.substr(1);

// Set control text
wndProfileWindow.SetControlText("lblProfile", Profile);

---

code:

---

if (Age == 1) {
    return " year"
}
else {
    return " years"
}

Personally I would not recommend declaring variables like that. It is bad practice and prone to errors/bugs if you're not carefull.

Always use var and always declare your global variables outside functions first.
