I currently have a form that disables a send button based on two textfields. The one field is a message box. I want to have it so that a person can't just put in a bunch of enters and spaces. I currently ahve a check for spaces, but charAt just returns a space :/ Here is what I want it to look like:
_sendComposeBtn.visible = true;
// if the length of the message is zero, don't let people send it
if (_messageLength == 0)
{
trace("hiding");
_sendComposeBtn.visible = false;
_realMessage = false;
}
_allSpaces = true;
// start with allSpaces true. If there is a nonspace (or non-enter character then hide send button
for (i = 0; i < _bigMessageTextField.length; i++)
{
if (_bigMessageTextField.text.charAt(i) != " " && _bigMessageTextField.text.charAt(i) != (ENTER_CHARACTER))
{
trace("not a space");
_allSpaces = false;
}
}
if (_allSpaces == true)
{
_sendComposeBtn.visible = false;
}
You can say:
_bigMessageTextField.text.charAt(i) != String.fromCharCode(13)

What I have done will probably be confusing but I tried doing it by replacing every letter to nothing until it finds a space.
for (int i = 0; i < mening.length(); i++) {
if ((int)mening.charAt(i) != 32 && stop == false) {
mening = mening.replace(String.valueOf(mening.charAt(i)), "");
} else {
stop = true;
break;
}
}
Just split string by space, remove the first item and join the rest together.
mening = mening.split(' ').slice(1).join(' ');
I have manage to open up 6 charts for 6 different currency pairs. Instead of open up position on 6 different pairs, it made 6 trades of the same pair. How do I fix it?
string symbol[];
for(int i=0; i > maxNoOfTrades; i--)
{
symbol[i]=PositionGetString(POSITION_SYMBOL);
if(symbol[i]==EURUSD)
return true;
if(symbol[i]==GBPUSD)
return true;
if(symbol[i]==USDJPY)
return true;
if(symbol[i]==USDCHF)
return true;
if(symbol[i]==USDCAD)
return true;
if(symbol[i]==AUDUSD)
return true;
}
return false;
If you want to open a marked Order directly, it is called Position in MQL5.
So you have to open a Position.
Opening a Order will not be marked, only e.g. a Stop / StopLimit Order.
Opening a Position e.g. by following Code:
void OpenBuyPosition(){
for (int attempt = 0; attempt < TRADE_RETRY_COUNT; attempt++){
// Vorbereitung / Zuordnung der Variablen
double lots = Entry_Amount;
ulong ticket = posTicket;
MqlTradeRequest request;
MqlTradeResult result;
ZeroMemory(request);
ZeroMemory(result);
request.action = TRADE_ACTION_DEAL;
request.symbol = _Symbol;
request.volume = lots;
request.type = ORDER_TYPE_BUY;
request.price = Ask();
//request.type_filling = ORDER_FILLING_FOK;
request.type_filling = orderFillingType;
request.deviation = 10;
//request.sl = stopLoss;
request.sl = 0;
//request.tp = takeProfit;
request.tp = 0;
request.magic = Magic_Number;
request.position = ticket;
request.comment = IntegerToString(Magic_Number);
bool isOrderCheck = CheckOrder(request);
bool isOrderSend = false;
if (isOrderCheck){
ResetLastError();
isOrderSend = OrderSend(request, result);
}
if (isOrderCheck && isOrderSend && result.retcode == TRADE_RETCODE_DONE){
return;
}
Sleep(TRADE_RETRY_WAIT);
Print("Order Send retry no: " + IntegerToString(attempt + 2));
}
}
You can switch the variable for your needed Symbol with you own code.
Also the Type from Buy to Sell ;-)
I've been given the following exercise but can't seem to get it working.
//Remove duplicate characters in a
// given string keeping only the first occurrences.
// For example, if the input is ‘tree traversal’
// the output will be "tre avsl".
// ---------------------
var params = 'tree traversal word';
var removeDuplicates = function (string) {
return string;
};
// This function runs the application
// ---------------------
var run = function() {
// We execute the function returned here,
// passing params as arguments
return removeDuplicates;
};
What I've done -
var removeDuplicates = function (string) {
var word ='';
for(var i=0; i < string.length; i++){
if(string[i] == " "){
word += string[i] + " ";
}
else if(string.lastIndexOf(string[i]) == string.indexOf(string[i]))
{
word += string[i];
}
}
return word;
};
I'm not allowed to use replaceAll and when I create an inner for loop it doesn't work.
<script>
function removeDuplicates(string)
{
var result = [];
var i = null;
var length = string.length;
for (i = 0; i < length; i += 1)
{
var current = string.charAt(i);
if (result.indexOf(current) === -1)
{
result.push(current);
}
}
return result.join("");
}
function removeDuplicatesRegex(string)
{
return string.replace(/(.)(?=\1)/g, "");
}
var str = "tree traversal";
alert(removeDuplicates(str));
</script>
First of all, the run function should be returning removeDuplicates(params), right?
You're on the right lines, but need to think about this condition again:
else if(string.lastIndexOf(string[i]) == string.indexOf(string[i]))
With i = 0 and taking 'tree traversal word' as the example, lastIndexOf() is going to be returning 5 (the index of the 2nd 't'), whereas indexOf() will be returning 0.
Obviously this isn't what you want, because 't' hasn't yet been appended to word yet (but it is a repeated character, which is what your condition does actually test for).
Because you're gradually building up word, think about testing to see if the character string[i] exists in word already for each iteration of your for loop. If it doesn't, append it.
(maybe this will come in handy: http://www.w3schools.com/jsref/jsref_search.asp)
Good luck!
I get trouble when I try to create a check box in canvas.
My checkbox works well but I don't know how to store value of each item, that mean when user check row 1 , and then they move to another row check box still check row 1, and when user check row 1 and 2 and move to another row, check box will check row 1 and 2.
But I can't find out solution for this problem
modify your code to use selectTodelete as boolean array instead of int, about like shown below
// ...initialization of DataList
boolean[] selectTodelete = new boolean[2]; // instead of int
{ selectTodelete[0] = selectTodelete[1] = false; } // init array
Command editCommand, backCommand,selectCmd, unselectCmd,selectAll;
//...
protected void paint(Graphics g) {
//...
for(int i =0 ; i<countRow; i++ ){
//draw background
//...
if(selectTodelete[i]){ // was selectTodelete == 1
//draw select dot at location for row 'i'
//...
}
// remove: you don't need that anymore: if(selectTodelete == 2) {
//draw select dot...
//}
// draw a checkbox before each item
// ...
}
}
public void commandAction(Command c, Displayable d) {
//...
if(c == selectCmd){
selectTodelete[selectedItem] = true;
}
if(c== unselectCmd){
selectTodelete[selectedItem] = false;
}
if(c == selectAll){
selectTodelete[0] = selectTodelete[1] = true;
}
repaint();
}
//...
}
update - answer to question in comments
I want to get RCID fit to checked it mean when row was checked I can get this id and when I use delete command it will delete all rows were checked
For that, you can expose selectTodelete for use outside of its class with getter, or, better yet, with method like below...
boolean isSelected(int elementNum) {
return elementNum >= 0 && elementNum < selectTodelete.length
&& selectTodelete[elementNum];
} // modelled after javax.microedition.lcdui.Choice.isSelected
...information exposed like that can be further used anywhere when you need it to deal with RCID, like eg in method below:
Vector useSelection(DataList dataList, DataStore[][] ds) {
Vector result = new Vector();
int count = ds.length;
for(int i = 0; i < count; i++ ) {
if (!dataList.isSelected(i)) {
continue; // skip non selected
}
System.out.println("RCID selected: [" + ds[i][5].cellText + "]");
result.addElement(ds[i][5]);
}
return result;
}
I was looking for a solution to the problem of getting a blank default when using a lookup in a field in Sharepoint. Kit Menke's solution to "Dropdown field - first item should be blank" question works perfectly for my first field with a lookup. But I can't make it work if have more that one field in the same list where I need to insert a blank for each lookup field (works only for the first field). I tried adding a new "Web Part" and applying the same code to the second field, but doesn't work. Any ideas? Thanks in advance
Follow-up to my answer here: Dropdown field - first item should be blank
Version 2.0 allows you to add the names of your dropdowns to dropdownNames in the MyCustomExecuteFunction function. As with the first one, this will work only with required single select lookup fields. Also, in order to edit the page again and update your Content Editor Web Part you may have to choose a value for your dropdowns otherwise you get the dreaded An unexpected error has occurred.. Good luck! :D

How about prepending a null option to the select menu of sharepoint.Like,
$('#idOfSelectMenu').prepend('<option value="" selected>(None)</option>');
I used this approach and append this code only in the NewForm.aspx because in EditForm.aspx it will override the selected option.
