Flex Datagrid + Tab Navigator - apache-flex

I have a several datagrids (with data being retrieved from some map service).
I want to place these data grids within seperate tabs of a tab navigator. All works fine apart from the first tab which always ends up without any datagrid in it.
I have tried creation policy="all" and stuff but the first tab always is empty. Does anybody have any ideas as to why the first tab is always empty.
Any workarounds.
Thanks
var box:HBox=new HBox();
var dg:DataGrid = new DataGrid();
dg.dataProvider = newAC;
box.label=title.text;
box.addChild(dg);
tabNaviId.addChild(box);
tabNaviId.selectedIndex=2;
resultsArea.addChild(tabNaviId);
dg is datagrid that is being filled up. The above code is in a loop, in each loop i am creating an Hbox+datagrid. then i am adding the Hbox to the navigator and final adding the navigator to resultsArea (which is a canvas).
The above code works great apart from first time.
The end result i get is, having a tab navigator with first tab without any datagrid but the remaining tabs all have the datagrids. Any ideas as to why this is happening.
Call to a function called createDatagrid is made:
dgCollection.addItem(parentApplication.resultsPanel.createDatagrid( token.name.toString() + " (" + recAC.length + " selected)", recAC, false, callsToMake ));
In another Mxml component this function exists

and the tab navigator declared as

<mx:TabNavigator id="tabNaviId" width="622" height="274" creationPolicy="all">
</mx:TabNavigator>
</mx:VBox>
</mx:VBox>

Abstract, can we get the full code including the loop you mention, as well as the code where you create the TabNavigator?
It's possible that the TabNavigator already has an initial child, and all the children you're creating are being added after that.

Auto Update DropDown items in Datalist in Asp.net

I am Working on a Shop page where I want the Dropdownlist show the available Quantity . (Eg: if stock contains 2 items then Dropdownlist contains Items 1 followed by 2..)
Here's the code I attempted , I have no idea in which event i should put it.
`
Code:
connect cu = new connect();
System.Web.UI.WebControls.Label Label8 = (System.Web.UI.WebControls.Label)DataList1.FindControl("modelnoLabel");
//Modelnolabel contains model no
cu.cmd.CommandText = "select qty from stock where modelno=#mod";
//qty is retrived based on modelnolabel text of datalist
cu.cmd.Parameters.Clear();
cu.cmd.Parameters.AddWithValue("#mod", Label8.Text);
int qty = Convert.ToInt16(cu.cmd.ExecuteScalar());
if (qty < 5 && qty > 0)
{
(DataList1.FindControl("DropDownList1") as DropDownList).Items.Clear();
for (int i = 1; i < qty + 1; i++)
{
(DataList1.FindControl("DropDownList1") as DropDownList).Items.Add(Convert.ToString(i));
}
}
else
{

How can I determine network and broadcast address from the IP address and subnet mask?

For example:
IP Address: 130.45.34.36
Mask: 255.255.240.0
What would be Net ID/Subnet Address, and
Broadcast Address?
Let's write both in binary:
130.45.34.36 = 10000010.00101101.00100010.00100100
255.255.240.0 = 11111111.11111111.11110000.00000000
A bitwise AND between the two would give us the network address:
10000010.00101101.00100010.00100100 (ip address)
AND
11111111.11111111.11110000.00000000 (subnet mask)
=
10000010.00101101.00100000.00000000 = 130.45.32.0 (the resulting network address)
A bitwise OR between the network address and the inverted subnet mask would give us the broadcast address:
10000010.00101101.00100000.00000000 (netadress)
OR
00000000.00000000.00001111.11111111 (inverted subnet mask)
=
10000010.00101101.00101111.11111111 = 130.45.47.255 (broadcast address)

Code example based on Malt's answer:
const
ipadr = '130.45.34.36',
subnet = '255.255.240.0',
ipadrs = ipadr.split('.'),
subnets = subnet.split('.');
let networks = [],
broadcasts = [];
for (let i in ipadrs) {
networks[i] = ipadrs[i] & subnets[i];
}
console.log('netaddress: ', networks.join('.')) // netaddress: 130.45.32.0
for (let i in networks) {
broadcasts[i] = networks[i] | ~subnets[i] + 256;
}
console.log('broadcast address: ', broadcasts.join('.')) // broadcast address: 130.45.47.255
Another short cut for broadcast address calculation after getting netwotk address is:
calculate total no of hosts (in this case it is 2^12 = 4096)
Divide it by 256(in this case it is 16) and add the result - 1(in this case 15) in *corresponding octet(in this case second octet i.e.
32+15=47) and make other octet 255
*we can get the corresponding octet by looking at the no of hosts. e.g if the no of hosts are greater than 256 then we have to add it to the 2nd octet of network address and so on
typescript version
function getBroadcastAddress({ address, netmask }: NetworkInterfaceInfo) {
const addressBytes = address.split(".").map(Number);
const netmaskBytes = netmask.split(".").map(Number);
const subnetBytes = netmaskBytes.map(
(_, index) => addressBytes[index] & netmaskBytes[index]
);
const broadcastBytes = netmaskBytes.map(
(_, index) => subnetBytes[index] | (~netmaskBytes[index] + 256)
);
return broadcastBytes.map(String).join(".")
}
/*
// test
getBroadcastAddress({ address: "192.168.1.93", netmask: "255.255.255.0" }) == '192.168.1.255'

How to draw and resize polygon using mouse

In my web application i need to draw shapes in the image using mouse.But i was struck draw and resize polygon..i have dawned polygon..How to resize it?
i can able to draw polygon using the above code.
But i need to resize it..any idea to resize the drowned polygon?
Please refer the below code.
private function onDrawTriangle() : void {
var ui:UIComponent = new UIComponent();
drawPanel = new Sprite();
drawPanel.graphics.clear();
drawPanel.graphics.lineStyle(2, 0xFF0000);
drawPanel.graphics.beginFill(0xDEFACE);
drawPanel.graphics.drawRect(0,0,300,300);
drawPanel.graphics.endFill();
ui.addChild(drawPanel);
addChild(ui);
ui.x = 20;
ui.y = 20;
_lineArr = new Array();
line = new Shape();
drawPanel.addEventListener(MouseEvent.CLICK,onAddPoint);
}
private function onAddPoint(evt:MouseEvent) : void {
if(numSpot <= 10) {
var point:Sprite = new Sprite();
point.graphics.clear();
point.graphics.lineStyle(0,0x0000FF);
point.graphics.beginFill(0x0000FF);
point.graphics.drawCircle(0,0,5);
point.graphics.endFill();
point.x = evt.localX;
point.y = evt.localY;
_lineArr.push({x:point.x,y:point.y});
drawPanel.addChild(point);
if(numSpot > 0) drawLine();
numSpot++;
}
}
private function drawLine() : void {
line.graphics.clear();
line.graphics.lineStyle(2,0x000000);
if(_lineArr.length > 2) line.graphics.beginFill(0xFF0000,0.5);
line.graphics.moveTo(_lineArr[0].x,_lineArr[0].y);
for(var i:int=1;i<_lineArr.length;i++) {
line.graphics.lineTo(_lineArr[i].x,_lineArr[i].y);
}
line.graphics.lineTo(_lineArr[0].x,_lineArr[0].y);
if(_lineArr.length > 2) line.graphics.endFill();
drawPanel.addChildAt(line,0);
}
Rather pushing points to array you may push the point(sprite variable).
Have a look on the modified codes for the above codes where I added some more events to re size the polygon
Here is the sample code:
private function onDrawTriangle() : void {
var ui:SpriteVisualElement = new SpriteVisualElement();
//ui.x = 20;
//ui.y = 20;
addElement(ui);
drawPanel = new Sprite();
drawPanel.graphics.clear();
drawPanel.graphics.lineStyle(2, 0xFF0000);
drawPanel.graphics.beginFill(0xDEFACE);
drawPanel.graphics.drawRect(0,0,300,300);
drawPanel.graphics.endFill();
ui.addChild(drawPanel);
_lineArr = new Array();
line = new Shape();
drawPanel.addEventListener(MouseEvent.CLICK,onAddPoint);
}
private function onAddPoint(evt:MouseEvent) : void {
if(numSpot <= 10) {
var point:Sprite = new Sprite();
point.graphics.clear();
point.graphics.lineStyle(0,0x0000FF);
point.graphics.beginFill(0x0000FF);
point.graphics.drawCircle(0,0,5);
point.graphics.endFill();
point.x = mouseX;
point.y = mouseY;
point.addEventListener(MouseEvent.MOUSE_DOWN , onDown);
_lineArr.push(point);
drawPanel.addChild(point);
if(numSpot > 0) drawLine();
numSpot++;
}
}
private function drawLine() : void {
line.graphics.clear();
line.graphics.lineStyle(2,0x000000);
if(_lineArr.length > 2) line.graphics.beginFill(0xFF0000,0.5);
line.graphics.moveTo(_lineArr[0].x,_lineArr[0].y);
for(var i:int=1;i<_lineArr.length;i++) {
line.graphics.lineTo(_lineArr[i].x,_lineArr[i].y);
}
line.graphics.lineTo(_lineArr[0].x,_lineArr[0].y);
if(_lineArr.length > 2) line.graphics.endFill();
drawPanel.addChildAt(line,0);
}

Flex sort Datagrid with custom compareFunction (sort numbers numerical and text alphanumerical)

I need following result.
All numbers use numeric sorting and all strings use alphanumeric sort. Further more , the numeric values should be listed before the string values:
Example:
before "i","9","89","0045","b","x"
after "9","0045","89","b","i","x"
My current code looks like this: (numeric sort works but my strings are distributed to the top and bottom?! -> "b","x","9","0045","89","i")
public function compareFunction(obj1:Object, obj2:Object):int {
var id1:String = (obj1 as WdProblem).id;
var id2:String = (obj2 as WdProblem).id;
if(id1.replace(' ', '') == "n") {
var sdld:int = 0;
}
var num1:int = Number(id1);
var num2:int = Number(id2);
if(stringIsAValidNumber(id1) && stringIsAValidNumber(id2)) {
if(num1 == num2) {
return 0;
} else {
if(num1 > num2) {
return 1;
} else {
return -1;
}
}
} else if(!stringIsAValidNumber(id1) && !stringIsAValidNumber(id2)) {
return ObjectUtil.compare(id1, id2);
//return compareString(id1, id2);

My suggestion is to break it down into it's constituent parts especially if you have a scenario like this with 1 or more priority sorts. The key is to move onto the next sort only when the first sort returns they are equal.
For your case, I would build 2 sorts, one for numeric and the other for alpha-numeric, then your main sort can prioritize these by calling the sub-sort.
For example I have something similar:
private function sort2DimensionsByIncomeVsTime(a:OLAPSummaryCategory, b:OLAPSummaryCategory, fields:Array = null):int
{
var sort:OLAPSort = new OLAPSort();
var incomeSort:int = sort.sortIncome(a, b);
var nameSort:int = sort.sortName(a, b);
var yrSort:int = sort.sortYear(a, b);
var moSort:int = sort.sortMonth(a, b);
if (incomeSort == 0)
{
if (nameSort == 0)
{
if (yrSort == 0)
{
//trace(a.name, a.year, a.month, 'vs:', b.name, b.year, b.month, 'month sort:', moSort);
return moSort;
}
else return yrSort;
}
else return nameSort;
}
else return incomeSort;
}
I use following sort function for AlphaNumeric sorting:

j script runtime error: object requiered

I am working on the platform confirmit, which creates online surveys. This is a script node that results in the runtime error "object required", I would be grateful if you could help me fix it.. It is supposed to check whether certain codes hold 1 or 2 in the questions q2b and q3a (questions are referenced with the function f() - f(question id)[code]) - the
'//skip ?' part. Then it recodes a maximum of four of the codes into another question (h_q4) for further use.
var flag1 : boolean = false;
var flag2 : boolean = false;
//null
for(var i: int=0; i <9; i++)
{
var code = i+1;
f("h_q4")[code].set(null);
}
f("h_q4")['95'].set(null);
//skip ?
for(var k: int=1; k <16; k+=2)
{
var code = k;
if(f("q2b")[code].none("1", "2"))
flag1;
else
{
flag1 = 0;
break;
}
}
if(f("q3a")['1'].none("1", "2"))
flag2;
if(flag1 && flag2)
f("h_q4")['95'].set("1");
//recode
else
{
var fromForm = f("q2b");
var toForm = f("h_q4");
const numberOfItems : int = 4;
var available = new Set();
if(!flag1)
{
for( i = 1; i < 16; i+=2)
{
var code = i;
if(f("q2b")[i].any("1", "2"))
available.add(i);
}
}
if(!flag2)
{
available.add("9");
}
var selected = new Set();
if(available.size() <= numberOfItems)
{
selected = available;
}
else
{
while(selected.size() < numberOfItems)
{
var codes = available.members();
var randomNumber : float = Math.random()*codes.length;
var randomIndex : int = Math.floor(randomNumber);
var selectedCode = codes[randomIndex];
available.remove(selectedCode);
selected.add(selectedCode);
}
}
var codes = fromForm.domainValues();
for(var i = 0;i<codes.length;i++)
{
var code = codes[i];
if(selected.inc(code))
{
toForm[code].set("1");
}
else
{
toForm[code].set("0");
}
}
}
the first part of the code (//null) empties the 'recepient' question to ease testing
.set(), .get(), .any(), .none() are all valid
