When the download is complete I can enter other commands to the server. If I have ns.DataAvailable, when I enter the command to my server to disconnect (the server should return "Disconnected") I receive a part of the transferred file (several words from it). As if there is still data in the stream.
But when the ns.DataAvailable is absent from the while loop, when I enter the command for download, the download begins but never ends. I have to close the client and then the buffer file is at 196 kb.
I am testing the application on my computer - both the client and the server (for an IP I am using localhost) so there shouldn't be a difference.
Still learning...

Their relative priority (and hence the percentage of CPU cycles allotted to each of them) will depend on which process is in front!

In FirstWindow class:
* Has progress bar object named "progressBar1".
* Its value is updated in this class as the process runs.
In SecondWindow class:
* Has progress bar object named "pbSecond".
* This SecondWindow class invokes FirstWindow class but does not use (display) the
FirstWindow GUI.
* This SecondWindow sends the data to FirstWindow the data to be processed and save to the file.
Now, I had this kinda of crazy idea to try and was amazed it does work! I'm not certain on how this works... passing the pointer of the object?
FirstWindow class has this property:
public ProgressBar pBar
{
set { progressBar1 = value; }
}
public int DumpRFData(byte[] dat)
{
pBar.Maximum = dat.length;
for (int i = 0; i < dat.length; i++)
{
progressBar1.value = i;
... code sippet (for retriving dump data)
}
}
now in SecondWindow class:
public int DumpData()
{
byte[] data = new byte[1000];
FirstWindow fw = new FirstWindow();
fw.pBar = pbSecond;
fw.DumpRFData(data);
}
when the DumpRFData is invoked, the progress bar in SecondWindow is updated as the process in FirstWindow runs.
How could that be happening? Processed from the pointer or what?

It's not a pointer, it's a reference. This is pretty ugly, your dumpRFData method should be outside any UI class.

right... I am in the middle of refactoring my source code to clean up the repeated functions and capsulate the classes with its appropriate methods.

Hi,
I need some urgent help on something.
I need to convert Expression<Func<T1, bool>> to Expression<Func<T2, bool>>.
I have a funtion that does T2 = Convert(T1)
In other words I need a function that does something like:
Expression<Func<T2, bool>> Convert(Expression<Func<T1, bool>> pSource) {
Expression<Func<T2, bool>> vResult;
...
...
...
T2 vOutpuParameter = Convert(vInputParameter);
...
...
...
return vResult;
}
Does anyone have any clues?

Hello
I'm trying to find some idea / method to draw railway pattern using Graphics gdi+
Google map gives a example to do some, I do not need to do exactly the same but something that can looks like a railway
The source information is an array of PointF
I'd a look on Pen.CompoundArray but I do not understand how it works from an atrray of PointF
Thanks for any help / suggestion

You mean a railway track ? I guess you draw two lines next to each other, then you draw small lines across it. I would think the best way to do that, would be to create a brush that defines a piece of track, then use that to draw your line.

This is the obvious "brute force" way : needs a lot of calculation awikll fatten the code I really do not want to use that way
I would think the best way to do that, would be to create a brush that defines a piece of track, then use that to draw your line.
I also think that it will be a good way but I do not know how to define the brush ?
Do I have to create an external image ?

You create a brush from a Bitmap, so you can load that from a file, or just draw it. In fact, I think the class you want is called BitmapBrush

You'll probably have to draw over the line twice. Read up on the compoundarray to get it to draw a double line (your railway lines). Then draw over that with a thick line and custom dash style to get sleepers.

Moving an array element to a variable.
When I started I didn't think just taking an element and copying to a variable was such a hassle.
OK, I have a string array defined as:
public static string[] Trux_Info = new string[20];
and I have a varaible define as
public static string port_in = "";
Now I thought that something like
port_in = Trux_Info[3]
would work. It didn't. I tried Trux_Info.GetValue(3). It didn't work right.
I know Trux_Info has info I can print to screen\file and the right info is there. I even passed the array across child, parent and back to a different child, the info is there.
I really need this element to go to this single variable, because after this happens then the processing can begin.
Any and all suggestion are appreciated.
Thanks

I tried it:
public static string[] Trux_Info = new string[20];
public static string port_in = "";
private void button1_Click(object sender, EventArgs e)
{
Trux_Info[0] = "Hello";
Trux_Info[1] = "There";
Trux_Info[2] = "This";
Trux_Info[3] = "Is";
Trux_Info[4] = "A";
Trux_Info[5] = "Test";
port_in = Trux_Info[3];
MessageBox.Show(port_in);
}
It show "Is" - which is what I would expect.
So, there is something you aren't telling us. Give us a cut-down-but-still-not-working sample of the code that isn't doing it's job, and tell us what it is doing instead.

Griff is right. There's something you're not telling us. What IS it doing and what are you EXPECTING it to do?? We also need to see a more complete code snippet showing the offending code.

|
|
|

Ok
It's one of those things where another of section of code was causing the problem. It had nothing to do with the array. Problem fixed array transfered properly.
Say it with me now, ROOKIE!!!!!!!!!!!!!!
I do appreciate the expediant answers. Consider this line/thread closed
Thanks

Hi Everyone,
I have a project which was written long time back. Now we are in position to convert into C# source code but we found that we donot have any source code.
I need two favors from you.
1. How to convert the ocx file into C# source code without having the source code
2. How to convert VC++ source code into C# soruce code.
Thanks in advance

Why? If your COM component works well, just use it in a C# application (via COM interop).
If you're stuck with the 'conversion' requirement, I suppose the easier solution is implementing from scratch the COM object functionality (i.e. 'the black box' way) in C# (in other words, I believe reverse engineering is not a good solution of your problem).

For a C++ and C# expert the task should be fairly straightforward (if you were an expert of both languages then you probably wouldn't do or ask about...).
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi Pallini,
Thanks for your response.
1. Actually I donot know what are the functions are being used by this application(ocx). I am also thinking to write from the scratch, but I do not have source code, so that I can chop the function that is not needed.
2. I was looking the easier way to convert the application. Anyways I will take your suggestions.

1) Learn assembler. Disassemble OCX. Spend lots of time working out what the heck is going on. Code it in c#
2) Learn C++. Learn C#. Translate.
To be honest, if you are lacking the source code for the OCX, then the best thing you can do is re-write it from the original specification. Or (more likely) write the spec from the OCX behaviour, and then rewrite the OCX.
Good luck - you may need it...

There are no conversion tools and nothing that is going to generate any kind of C# code for you. You have no choice but to study the existing OCX control and redesign and recode the control by hand in C#, or any other language for that matter.

I don't know how to put timer in form that clock would be moving..
public void Start()
{
timer1.Enabled = true;
this.Refresh();
}
public void Stop()
{
timer1.Enabled = false;
}
private void timer1_Tick_1(object sender, EventArgs e)
{
this.dateTime = DateTime.Now;
this.Refresh();
}
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
dateTime = DateTime.Now;
this.analog_size(sender, e);
}
With this code i get current time and clock pointers are also showing the correct time..but they are not moving..what should i do to make them move??
Thanks

As far as I can see you wait for the timer to tick, but the timer isn't ticking. In Start() and Stop() methods you should use timer1.Start() and timer1.Stop() rather than timer1.Enabled .
Still learning...

Thanks...but i found out there was problems with drawing seconds pointer...so both enabled and .start works now. Thanks anyway
|

How to make lets say new timer timer2_tick...to start ticking from 0 when start button pressed and everytime seconds come till 60 1 minute ++...when minutes come to 60..1 hour ++...and end when stop button pressed..i have to build stopwatch in other words..Now clock for datetime.Now works..so some little changes and stopwatch will work to..
Thanks for any help
