Timer Class Help - C# Discussion Boards

I just installed directX 9.0 and it sits in the directory DXSDK, how to do set my C# to talk to the directX components???

Thanks

samuel

You asked a mouthfull. And the SDK is more C++ oriented far as when i last checked it out.

In a C# App you can Add Reference..."Microsoft.DirectX" and "Microsoft.DirectX.Direct3DX" (for the version you want to work with)
of course DirectSound etc aswell if you need it.

However if you are wanting to make 3D games using DX then this might be a better starting point:

Microsoft XNA Studio
http://msdn.microsoft.com/xna/[^]

Comes with a space shooter game and all source code in C# all working. Could be eaiser for you if you are new to DX

Other options are less 'clean' for use with C#, but there is alow of code available on the net just google it.

Either way good luck

Always more to learn, and i wouldn't have it any other way.

Good day,

I want to justify the text in my listbox. I've try to insert items in which both have the same length however the amount area won't align considering both items have the same length. How can I make the listbox justify its items so that both amount are on the right edge?
Here is the code that i've tried but items arent justified:

<br />
private void Form1_Load(object sender, EventArgs e)<br />
{<br />
    string stramount1 = "900.00";<br />
    string stramount2 = "3400.00";<br />
    string description1 = "Basic Salary......................"+stramount1; <br />
    string description2 = "Basic Salary....................."+stramount2;<br />
<br />
    listBox1.Items.Add(description1);<br />
    listBox1.Items.Add(description2);<br />
}<br />

thanks.

Simple answer? You dont

You could try measuring the text width and calculate the remaining space and fill it with calulated amount of spaces however you wont be able to get exact alignment as spaces in each font have a set size more than one pixel.

Delete your listbox and add a listview control and use that

You can add columns (so each part has a header), change alignment of each column and its easy to add items:

<br />
ListViewItem MyItem = new ListViewItem(new string[] {"Bob Marley","$10,000"} );<br />
listView1.Items.Add(MyItem);<br />

or

<br />
string sDescription = "Bob Marley";<br />
string sSalary = "$10,000";<br />
<br />
ListViewItem MyItem = new ListViewItem(new string[] { sDescription, sSalary });<br />
listView1.Items.Add(MyItem);<br />

Just to be clear, this is all considering there is more than one column... if you just need the salary in there and nothing else and want it right aligned you set the RightToLeft property to Yes. Thought i should cover all bases Smile | :)

Hi,

if you really want to do that with a ListBox there are two ways:

1.
select a "non-proportional" font (such as "Courier New") where all characters
have the same width; then adjust the spaces/dots/whatever in your strings so
they all have the same length.

or
2.
Choose to draw the ListBox items yourself, by setting DrawMode to OwnerDraw;
and provide a handler for the DrawItem event (similar to a paint handler when
drawing in say a Panel). You do know the items in a ListBox dont have to be
strings ? They can be instances of whatever class you come up with, and
your DrawItem handler could make use of that...

Smile | :)

Ok to start i'll tell you what im doing, I have a InterOpWindow class that i created. It basically allows me easy talking between Process's and Thread's allowing me to just send strings all over however i like.

eg, to setup a window to talk to:

C#

<br />
InterOpWindow MyCommandWindow = new InterOpWindow("some_window_name");<br />
MyCommandWindow.evDataCommandRecieved += new InterOpWindow.delDataRecieved(OnDataCommandRecieved);<br />
<br />
static void OnDataCommandRecieved(string sData)<br />
{<br />
	MessageBox.Show("Data: " + sData);<br />
}<br />

and to send data and check a window reference:

C#

<br />
InterOpWindow.SendRemoteMessage("some_window_name", "my data message");<br />
InterOpWindow.CheckRemoteWindow("some_window_to_check");<br />

Nice and easy... just how i like it, im happy i got it working as i've only been C# coding for about 3 weeks heh.

Which is where i come to my problem with the timer class. What i assumed was fine was to keep enabling and disabling it to start and stop the monitoring process for command sending timeouts. However after the timer being used (and working) it seems to be 'dead' if i try to disable then enable it... the Tick event never fires.

Is the object being disposed? does it need a container to stay active? any thoughts would be great...

For now im just leaving it enabled for good and using a var to count around 3 ticks (1 second each) for timeout.

Of course i could have just stuffed up completely and its something small... ya never know Wink | ;)

C#

<br />
public class InterOpWindow : NativeWindow<br />
{<br />
    ...<br />
    private Timer tmrTimeout = new Timer();<br />
    ...<br />
    public InterOpWindow(string sLocalWindowName)<br />
    {<br />
        ...<br />
        tmrTimeout.Tick += new EventHandler(tmrTimeout_Tick);<br />
    }<br />
}<br />

thats basically how i've set it up, any ideas would be great... thanks Smile | :)

Good guess. The MSDN documentation on Forms.Timer clearly states on Enabled:
"The timer is not subject to garbage collection when the value is true."

This means there are two ways to keep a Forms.Timer alive (i.e. not collected):
1. make sure it is running
2. make sure to keep a reference to it (in a private member of one of your classes
as opposed to in a local variable of a method that has returned)

Wink | ;)

Thanks for the reply, i swear i checked MSDN and google... but ya can't always get a straight thought in ya head when you a little fustrated Wink | ;)

Seems i'll have to keep the way im doing it, as its already a private member of the class and its still being difficult.

I could use the API Timer i guess but that seems messy yes? Is there any other Timers hidden somewhere in this mind bogginly huge framework that might suit?

Always more to learn, and i wouldn't have it any other way.

Hi,

1.
There is also Threading.Timer and Timers.Timer; both of them run their handler
on a separate thread, not the GUI thread. And you must keep them alive too.

2.
I fail to see how exactly your timer might be collected: if you are able
to set its Enabled property true again, that means you are holding a reference,
so I believe something else is going on. If you need more help, show us the code !

Smile | :)

Well i did some more testing

I moved the class to a new blank project and forced some timeouts and its working fine, enabled/disabled/enabled etc. Go figure :/

So its bound to be something else, i'll get onto the other coders in the project and perhaps break one of their arms for making me think my class was broke Smile | :)

You dont need arm parts to fix a timer...

I've done a web site that allows file access only to certain users (registered). If a user is not logged in it has to do it before access to files.It works with cookies.
Is really simple to do this steps with the browser but I have no ideas on how to do it with c# code... I thought that I can do the login by calling the page login.aspx and to put the autenthication credential in the http body( POST METHOD). The question is: how can I do it?
I'd like to do: CALL FROM CODE THE URL "www.mywebsite.com/login.aspx?username=myid&password=pass"
(this is the GET method I'd like to use POST of http)
How can I intercept the data from the server?
Thanks to everyone will reply me...

Is this what you are after?

I assume you know how to read post/get submissions from a asp.net webpage... its a little hard to read your english so i assumed you want something similar to the link i posted?

To give you a more 'workable' idea:

New C# Project, add a button and a listbox (make it fairly wide)
add a new using:

<br />
using System.Net;<br />

then add this to the button code:

<br />
WebRequest MyRequest = WebRequest.Create("http://mmo.shadowdevelopment.com/default.aspx?TEST=Bob");<br />
WebResponse MyResponse = MyRequest.GetResponse();<br />
<br />
for (int iC = 0; iC < MyResponse.Headers.Count;iC++ )<br />
{<br />
	listBox1.Items.Add(MyResponse.Headers.Keys[iC] + ": " + MyResponse.Headers[iC]);<br />
}<br />
MyResponse.Close();<br />

Thats a link to a test page on my domain so it wont be up forever Wink | ;)

but as you can see there is a Set-Cookie: header you need to read this value and re-send it with any other request (and each time it will send a new one back) that will identify your requests with the correct session store on the server and allow you to do whatever you want while being logged in on a website using a normal c# application.

firs I want to thank you for replying me.
GIS stands for gegraphic information system.in this project as I told you I'm looking for a control in c# that has the ability to view any kind of map;also I want to define tools for zooming ,surching and etc.

Why not just use google maps ?

i need to know that if a C# application is maintainig a database and if data is entered in a mobile application built in j2me then how it can be done that the data entered will be stored in the C# application? i m anxiously waiting for replies.Thanks

I'm not sure I follow, you seem to be talking about two apps connecting to the same data store. If this is true, it will just work, the j2me app updates the common database, and the C# app will find it the next time it reads it.

Have you tried searching the web for an answer? Searching will almost always give you a faster and better answer than forum answers. Especially since your post contains no specific question; are you having problems printing? Errors? Don't know how to do printing?

A quick Google search reveals this: Preview and Print from Your Windows Forms App with the .NET Printing Namespace[^]

The link Judah provided looks like a start. Like Christian said, shouldn't be any different. Just use what the framework offers and let the OS do the rest.
