I have in Form1 a click event for saving:
<pre class="prettyprint private void saveBaseFileToolStripMenuItem_Click(object sender, EventArgs e)
{
string path_exe = Path.GetDirectoryName(Application.LocalUserAppDataPath);
wireObject1.Save(path_exe,Lock,pictureBox1);
}[/code]
Now in WireObject class i have a Save function:
<pre class="prettyprint public void Save(string path , bool Locked , PictureBox pb)
{
string fn;
fn = path + "\" + "DATABASE" + "\" + wo_name + "\" + wo_name + ".txt";
OptionsFile setting_file = new OptionsFile(fn);
setting_file.SetKey("File Name", fn);
setting_file.SetKey("Version", version);
setting_file.SetKey("picturebox.Width", pb.Width.ToString());
setting_file.SetKey("picturebox.Height", pb.Height.ToString());
setting_file.SetKey("Button Lock", Locked.ToString());
setting_file.SetListFloatKey("Coordinates_X", woc.Point_X);
setting_file.SetListFloatKey("Coordinates_Y", woc.Point_Y);
setting_file.SetListIntKey("ConnectionStart", connectionStart);
setting_file.SetListIntKey("ConnectionEnd", connectionEnd);
}[/code]
This is the WireObject class constructor:
<pre class="prettyprint class WireObject
{
public string lockObject;
private int idx;
public WireObjectCoordinates woc;
private List<int> connectionStart = new List<int>();
private List<int> connectionEnd = new List<int>();
private const string version = "01.00";
string wo_name;
public WireObject( string name )
{
wo_name = name;
woc = new WireObjectCoordinates();
}[/code]
Once in Form1 i enter any textBox then click a button its making an instance of the WireObject class with the text from the textBox:
<pre class="prettyprint wireObject1 = new WireObject(textBox3.Text);[/code]
For example i entered the textBox3 a name like Human so now the variable in WireObject name will be Human
Then im doing an instance for WireObjectCoordinates class wich just make an instance for some Lists:
WireObjectCoordinates have two constructors in this case im using the first one :
<pre class="prettyprint using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace AnimationEditor
{
class WireObjectCoordinates
{
public List<float> Point_X = new List<float>();
public List<float> Point_Y = new List<float>();
public WireObjectCoordinates()
{
}
public WireObjectCoordinates(WireObjectCoordinates w)
{
Point_X.AddRange(w.Point_X);
Point_Y.AddRange(w.Point_Y);
}[/code]
Then im doing a Save clicked the button WireObject class got a name and now after clicked the button and when its got a name im doing the Save:
This is the Save function in WireObject class:
<pre class="prettyprint public void Save(string path , bool Locked , PictureBox pb)
{
string fn;
fn = path + "\" + "DATABASE" + "\" + wo_name + "\" + wo_name + ".txt";
OptionsFile setting_file = new OptionsFile(fn);
setting_file.SetKey("File Name", fn);
setting_file.SetKey("Version", version);
setting_file.SetKey("picturebox.Width", pb.Width.ToString());
setting_file.SetKey("picturebox.Height", pb.Height.ToString());
setting_file.SetKey("Button Lock", Locked.ToString());
setting_file.SetListFloatKey("Coordinates_X", woc.Point_X);
setting_file.SetListFloatKey("Coordinates_Y", woc.Point_Y);
setting_file.SetListIntKey("ConnectionStart", connectionStart);
setting_file.SetListIntKey("ConnectionEnd", connectionEnd);
}[/code]
<br/>
First time i click and save its creating a new file text file this the content:
<pre class="prettyprint File Name = C:UsersChocoladeAppDataLocalAnimationEditorAnimationEditorDATABASEhelphelp.txt
Version = 01.00
picturebox.Width = 656
picturebox.Height = 422
Button Lock = False
Coordinates_X = 332,331,275,328,318,335,329,323,308,318,331,340,309
Coordinates_Y = 208,209,225,208,203,212,210,207,244,206,203,274,299[/code]
Now im doing some changes i didnt wuit the program just added more points for example or even didnt change anything but lets say i added some points.
Now i click and make save again.
Now the content of the text file is like that:
<pre class="prettyprint File Name = C:UsersChocoladeAppDataLocalAnimationEditorAnimationEditorDATABASEhelphelp.txt
Version = 01.00
picturebox.Width = 656
picturebox.Height = 422
Button Lock = False
Coordinates_X = 332,331,275,328,318,335,329,323,308,318,331,340,309
Coordinates_Y = 208,209,225,208,203,212,210,207,244,206,203,274,299
File Name = C:UsersChocoladeAppDataLocalAnimationEditorAnimationEditorDATABASEhelphelp.txt
Version = 01.00
picturebox.Width = 656
picturebox.Height = 422
Button Lock = True
ConnectionStart = 2
ConnectionEnd = 8
Coordinates_X=332,331,275,328,318,335,329,323,308,318,331,340,309,322,317,325,319,333,334
Coordinates_Y=208,209,225,208,203,212,210,207,244,206,203,274,299,210,208,213,210,207,219[/code]
Its adding everything again including the coordinates of the new points.
But what it should do is just updating the value/s of the keys i changed. If i added more points so the file suppose to look like this:
<pre class="prettyprint File Name = C:UsersChocoladeAppDataLocalAnimationEditorAnimationEditorDATABASEhelphelp.txt
Version = 01.00
picturebox.Width = 656
picturebox.Height = 422
Button Lock = False
Coordinates_X=332,331,275,328,318,335,329,323,308,318,331,340,309,322,317,325,319,333,334
Coordinates_Y=208,209,225,208,203,212,210,207,244,206,203,274,299,210,208,213,210,207,219[/code]
Im not sure where the problem is.
This is the code of the OptionsFile where im creating the setting_file and also Get and Set the key and values:

In other program i didnt have any problems like that when using the OptionsFile but then i didnt have the other functions GetListFloatKey and SetListFloatKey i had only GetKey and SetKey.
And yet im not sure where the problem is.
