Moving a control in runtime with c#, without using c++ api

Hi,

I'm trying to move a control while clicking on it. it works but very bad!

When i click the control down (panel), and start moving it, it is continuosly swaping between two position and i cant find a reason for that behaviour.

This is my code (only the event handlers):

<br />
        private void panel_MouseDown(object sender, MouseEventArgs e)<br />
        {<br />
            Console.WriteLine("mouse down");<br />
            Panel region = (Panel)sender;<br />
            <br />
            drag = true;<br />
        }<br />
<br />
        private void panel_MouseUp(object sender, MouseEventArgs e)<br />
        {<br />
            Console.WriteLine("mouse up");<br />
            drag = false;<br />
        }<br />
<br />
        private void panel_MouseMove(object sender, MouseEventArgs e)<br />
        {<br />
            if (drag)<br />
            {<br />
                this.SuspendLayout();<br />
                Panel region = (Panel)sender;<br />
<br />
                region.Location = new Point(e.X, e.Y);<br />
<br />
                Console.WriteLine("Panel position: (" + region.Left + "," + region.Top + ")" + "mouse position: (" + e.X + "," + e.Y + ")");<br />
                this.ResumeLayout();<br />
            }<br />
        }<br />

Someone has given me an answer to this problem using user32.dll but i want to have more control of the thing.

Can anyone help me?

Thx

Hello,

At the MouseDown you have to store the starting point:
_startDragPoint = new Point(e.X, e.Y);

At the MouseMove I suggest you to use a timer which only changes the Location every 100ms.
And add this logic:

if(TimerMovePad == null)
{
    this.TimerMovePad = new System.Timers.Timer();
    this.TimerMovePad.Interval = 100;
    this.TimerMovePad.Elapsed +=new System.Timers.ElapsedEventHandler(TimerMovePad_Elapsed);
}

if (TimerMovePad.Enabled == false)
{
    TimerMovePad.Enabled = true;
}

if(_movementok == true)
{
    _movementok = false;

    int delta_x = e.X - _startDragPoint.X;
    int delta_y = e.Y - _startDragPoint.Y;

    region.Location = new Point((region.Location.X + delta_x), (region.Location.Y + delta_y));
}

At the timer Elapsed, you then set the flag.

private void TimerMovePad_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
    TimerMovePad.Enabled = false;
    _movementok = true;
}

Hope it helps!

All the best,

Martin

Hi Martin,

While i was waiting for an answer i kept trying.

I got it! And it was pretty simple!

New code:

<br />
private void panel_MouseDown(object sender, MouseEventArgs e)<br />
        {<br />
            Panel region = (Panel)sender;<br />
<br />
            xi = e.X;<br />
            yi = e.Y;<br />
<br />
            drag = true;<br />
        }<br />
<br />
        private void panel_MouseUp(object sender, MouseEventArgs e)<br />
        {<br />
            drag = false;<br />
        }<br />
<br />
        private void panel_MouseMove(object sender, MouseEventArgs e)<br />
        {<br />
            if (drag)<br />
            {<br />
                Panel region = (Panel)sender;<br />
<br />
                region.Location = new Point((region.Left + (e.X - xi)), (region.Top + (e.Y - yi)));<br />
            }<br />
        }<br />

Basicly i think the problem is the diference between the coordinate system from the mouse and control

Other thing i dont understand is how does suspend/resume layout works as they weren't doing a thing.

Thx anyway,

Nuno

Use the Capture property of the control. That makes the control capture all mouse movement, even if you manage move the mouse fast enough to slip outside of the control:

private Point start;

private void movable_MouseDown(object sender, MouseEventArgs e) {
	Control c = (Control)sender;
	start = c.PointToScreen(e.Location);
	c.Capture = true;
}

private void movable_MouseUp(object sender, MouseEventArgs e) {
	Control c = (Control)sender;
	c.Capture = false;
}

private void movable_MouseMove(object sender, MouseEventArgs e) {
	Control c = (Control)sender;
	if (c.Capture) {
		Point mouse = c.PointToScreen(e.Location);
		c.Left += mouse.X - start.X;
		c.Top += mouse.Y - start.Y;
		start = mouse;
	}
}

Note: As this code uses the sender argument to reference the control, the code can be reused for the events of several controls that you want to be able to move.

It's used for more complex controls, for example when you want to add a lot of items to a list without having the list redraw itself for every item.

i don't understand what you are trying to do here.

Do you want to have a List of Lists of List?

put code in the second loop that does whatever you want done to each of the lists in fowardcurve.

Maybe if you explain what you are trying to do I can help more.

Hello
I am writing a file. The text of file is not in English, but it can be in chinese, arabic, spanish etc language. Currently i am testing for chinese language. But when the file is written, i can not find the exact text i have written. I mean after writing the file, when i open the file, it dowsn't display me the original text i have sent to be written.

Make sure you use Unicode when reading and writing the file. UTF-8 is typically used in files, but UTF-16 works as well and have the advantage of a mandatory Byte Order Mark identifying the encoding.

Unfortunately a lot of people still save with ANSI encodings which varies from system to system (due to ignorance I guess, but probably it did not help Microsoft named it the "Default" encoding which is an unfortunate name for something that is depricated).

Crystal Reports Database login prompt [modified]

Hi!!
I'm creating this aplication that uses crystal reports..
to bind data (after filling dataset) to report i'm using:

<br />
MyDataSet ds;<br />
...<br />
crDoc.Subreports[0].SetDataSource(ds);<br />
crDoc.Subreports[1].SetDataSource(ds);<br />
crDoc.Subreports[2].SetDataSource(ds);<br />
<br />
crViewer.ReportSource = crDoc;	<br />

and then a database login prompt shows.
there are 4 textboxes to fill:
'Server Name' - Enabled = false, Text = "MyDataSet"
'Database' - Enabled = false, Text = ""
'Login ID' - Enabled = true, Text = ""
'Password' - Enabled = true, Text = ""

and whatever i input it returns 'logon failed. please try again'..

anybody had a problem like that??
is there any solution/workaround to this?!

thanks for any help

-- modified at 9:30 Wednesday 13th June, 2007

i forgot to add that this happens only in release mode - in debug mode everything works fine. and the prompt shows only in one report.. i've got two other and they work fine..

you can adjust the keys that the object uses by selecting the relevant keys in the option of the shortcut keys in the object properties.

Collection serialization problem...

Shy Agam13-Jun-07 2:31

Shy Agam

13-Jun-07 2:31

Hello,

I have a collection class I wrote.
It is marked as Serializable.
Every class which instances are to be stored in the collection are marked as Serializable as well.
I create an instance of the collection in my main form, and handle it from there.
When I try to serialize the collection using a BinaryFormatter, I get an exception saying that my main form is not marked as Serializable.

Why on earth does it look for a Serializable attribute on the main form??
What am I missing here? Confused | :confused:

Thanks in advance,
Shy.

Here is the main concept of how stuff get done:

[Serializable()]
public class TaskCollection : KeyedCollection<......>
{
......
}

public partial class MainForm : Form
{
...

private TaskCollection tasks;

...

public void DoSave()
{
string fileName;

// Do stuff and figure out fileName

TaskSerializer.Serialize(tasks, fileName);
}

...
}

public static class TaskSerializer
{
...

public static bool Serialize(TaskCollection tasks, string file, out string errorMsg)
{
FileStream stream = null;

// Validation and preperations for serialization

try
{
// Validation and preperations for serialization

IFormatter formatter = new BinaryFormatter();
stream = new FileStream(file, FileMode.Create, FileAccess.Write);

formatter.Serialize(stream, tasks);

errorMsg = string.Empty;

return true;
}
catch (Exception ex)
{
errorMsg = ex.Message;

return false;
}
finally
{
if (stream != null)
{
stream.Close();
stream.Dispose();
}
}
}

...
}
