I am trying to insert a code block into the custom indicator wizard at Ninjatrader. They use C#. I've found a code block for what I want that produces eSignal's fractal index, I think they use javascript, and it inserts OK except for only 6 "expects ;" errors which I can fix. But at the end of this block, it gives an "expects statement" error. What ending statement goes there??? Will this revise the javascript version to Ninjascript OK? The last part of the code looks like this:
function verify() {
var b = false;
if (getBuildNumber() < 779) {
drawTextAbsolute(5, 35, "This study requires version 8.0 or later.",
Color.white, Color.blue, Text.RELATIVETOBOTTOM|Text.RELATIVETOLEFT|Text.BOLD|Text.LEFT,
null, 13, "error");
drawTextAbsolute(5, 20, "Click HERE to upgrade.@URL=http://www.esignal.com/download/default.asp",
Color.white, Color.blue, Text.RELATIVETOBOTTOM|Text.RELATIVETOLEFT|Text.BOLD|Text.LEFT,
null, 13, "upgrade");
return b;
} else {
b = true;
}
return b;
}
Ninjatrader's Ninjascript expects a closing statement right after the last "}" - What the heck is it? The whole code is here "http://forum.esignalcentral.com/showthread.php?threadid=22092

Hi guys.
I'm looking for a sample of ListView that contains some ListViewItems in XAML code.
I have been searching the web but I couldn't find any useful sample !
Could you guide me ?
Thanks.

Hi
sorry for bad subject!!
let me explain my project.
I create a Gate simulator ( AND - OR - XOR...) each gate is a user control.
user drag desired gates to page and then connect them to each other.
(for example the output of OR should connect to input of XOR gate)
I have no idea to how connect them to gather?!!
appreciate for your help.

Hi,
1.
you need "wires" to interconnect input and output pins of your gates. So in your approach, why not create some "Wire" user controls (either arbitrary size and orientation, or a horizontal and a vertical having arbitrary length).
2.
I wouldn't use user controls at all for a drawing or CAD app; just a simple Panel onto which you add "electronic components", which would be instances of "Wire" and "SomeGate", both derived from "ElectronicComponent"; keep them in a List<ElectronicComponent>; give them a "Draw" method so they paint themselves on a given Graphics; use the Panel's mouse events to grab, move, resize them. Then add logic to discover which components are connected to which, so you get a circuit.
Suggestion: have a look at the source of some drawing app, maybe Paint.NET

thanks for your help and idea.
I will try your idea. but my experience in draw and graphics is zero

you might have a look at my Sokoban article, it has some simple graphics; it does not however have click-and-drag.
If that does not help, maybe you should start with a simpler app first.

actually I don't want write this app, my teacher pressure on me to do this 
I will take a look at your articles,

after adding a key in app.config for format
i tried this, in the Main method
CultureInfo culture = (CultureInfo)CultureInfo.CurrentCulture.Clone();
culture.DateTimeFormat.ShortDatePattern = "dd-MMM-yyyy";
culture.DateTimeFormat.LongTimePattern = "";
Thread.CurrentThread.CurrentCulture = culture;
i was able to change pattern for short date, but what i want is that the datetimepicker format's property defaults
to what i set in config file.
like if i set the datetime format in config file to Long the rule will applay to entire application.
do i have to check and change manually for each control.
thanks

You could:
0) You could override the DateTime class with your own
1) You could setup a static method in your application that does it for you.
2) You could simply specify a string constant and use it when you call DateTime.ToString()
3) You could setup the culture object you've already got there as static, and the rest of the app could use it. (You would have to initialize it from the config file via a static method as well.
I would probably go with #3 myself.

#3 is fine
#0 isn't, as DateTime is sealed.

thanks for reply
first:
as i mentioned in my question, i was able to change the pattern of the format, not the format property
for option 2: it does not work for me, because i am actually showing the date in the datetimepicker
not into textbox control, so i'm not using DateTime.ToString()
for option 3:
do you mean that i have to access the static cultureinfo object every time i need to to display the date in
datetimepicker
or do i have to change the format manually in each datetimepicker contro on my form based on the cultureInfi
properties
excuse my bad english
thanks for the reply again

I don't know. I've never had to do what you're trying to do. Experiment with it. The benefit of creating a static culture object is that you don't have to recreate it every time you need it. It's always there, and it's always the same. I suspect that you can get away with setting the control when the form is constructed, and then forget about it.

yes, i can do that, but then i have to put it in each form in my application.
i'm looking if there is a way to do it globaly
do it in one place and this is it for the whole application
thanks anyway

Well, you could derive your own datetime control from the .Net DateTimePicker class, and set it in the constructor, but then you'd have to remember to use YOUR datetimepicker control instead of .Net's version...
If it were me, I would probably just take the easy way out and set the custom format on each control that needed it, and be done with it.

Hmm,
You could also create an Extension method if you are using .NET 3.5 or better.
|
|
|
|
|
what do you mean by extension method?
|
|
|
|
|
Well, an extension method is a new method declaration in 3.5 and above. Think of it as sort of a helper method and overload at the same time.
From MSDN:
'Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type.'
Example:
namespace ExtensionMethods
{
public static class MyExtensions
{
public static int WordCount(this String str)
{
return str.Split(new char[] { ' ', '.', '?' }, StringSplitOptions.RemoveEmptyEntries).Length;
}
}
}
In this example the extension method is WordCount which returns an int, and can be called using the construct:
String myString = "Hello World";
int count = myString.WordCount();
If you look at the string class you won't find a 'WordCount' method, it has been made a 'custom extension' of the string class.
So for your date picker you could create extension methods and customize the class how ever you would like with out inheritance etc.
Some good Extension Method Resources:
Extension Methods (C# Programming Guide)[^]
C# .NET Extension Methods 3.0[^]
I have run into this problem with the DateTimePicker and used this type of solution to solve the problem.
additionally if you do use an extension method for the DateTimePicker you can name it so the code reflects the fact that you have made a specialization to the date time returned. Ie. DateTimePicker.MyDateTime();
I think Luc has an article on this geared for the DateTime class.

ASP.net Ajax Control Toolkit Color Picker Extender have a SampleControlID property, that shows the selected color's hexadecimal color code value for further use. But some time for better ui visibility need, if you don't want that hexadecimal color code to appear in the same control, then here is the way to do that.
In this sample code below:
I used a TextBox (txtColor) as ColorPickerExtender's SampleControlID and TargetControlID.
I used a ImageButton(ibtnCollorPicker) with ColorPickerExtender's PopupButtonID.
Now, when I click on the ibtnCollorPicker, this will show the colorpicker. Any color selection done, will show the hexa value in the txtColor.
Method 1: (Mostly Used By Developers)
On color selection, the selected color of color picker becomes the both the fore color and background color of the textbox. So since the hexa value does not appear directly.
<asp:TextBox ID="txtColor" runat="server"></asp:TextBox>
<asp:ImageButton ID="ibtnCollorPicker" runat="server" ImageUrl="~/Images/color_button.png"
ToolTip="Pick Color"></asp:ImageButton>
<cc:ColorPickerExtender ID="txtColor_ColorPickerExtender" runat="server"
http://www.mindfiresolutions.com/Hiding-hexadecimal-color-code-in-ColorPickerExtenders-Sample-Control-679.php[^]
TargetControlID="txtColor" SampleControlID="txtColor"
OnClientColorSelectionChanged="changeColor"
PopupButtonID="ibtnCollorPicker">
</cc:ColorPickerExtender>
function changeColor(sender)
{
sender.get_element().style.color = sender.get_selectedColor();
}
It works fine but it has a small issue. After selection, if you highlight textbox text with the help of mouse, then the hexa value will appear again.
Method 2 contains solution of this.
Cheers,
Eliza

Hi All
Most applications need the ability to print reports of one sort or another.
Printing classes are tedious and difficult to program.
I am wondering: what do people on here do when you need printing capabilites (for reports etc)?

Initially one might feel that way but not once you get hold of them.

Depends on the need. Use crystal reports or SSRS if possible or else go with the Printing classes available.

I go with SSRS, it has all the functionality built-in that we need for all the projects I've worked on. It's also nice to have a separate Report project and be able to develop the Reports in VS2005.
Hold on a second here... Don't you think you might be putting the horse ahead of the cart?

Like d@nish says, it could be a daunting task at the begining but once you have written it once you can re-use it over and over again all the time. I wroyte my own some time ago when I needed one and I just add the class into my new projects now. Took a while to get it written but once I got it working it is great.
Excellence is doing ordinary things extraordinarily well.
