c# constructor issues

Ok hello sharpcorner

i been having a issue now for ages and cant seem to find out why its causing me issues but here is a lines of the code

Ok main form1

elfenlied_program_settings elf;
addingweapons elf_weap;
Parser elfenliedl;
gscadding elfy1;
//Parser parser = new Parser("model1887_sp");
public Form1()
{
InitializeComponent();
updater1.CheckForUpdates();
listBoxAdv1.Visible = false;
elf = new elfenlied_program_settings(listBoxAdv1,elfenliedl);
elf_weap = new addingweapons(richTextBoxEx1);
elfenliedl = new Parser("model1887_sp");
elfy1 = new gscadding(this, elf_weap);
elfy1.elfygsc = this;
timer1.Start();
elf.buttonX2 = buttonX2;
elf.elfenform = this;
// elfe.elfgsc = this;
buttonX2.Visible = false;
buttonX3.Enabled = true;
textBoxX6.Enabled = false;
elfenliedl.buttonX1 = buttonX1;
// last thing to add hopfully
if (Properties.Settings.Default.root.Equals("First"))
{
if (Directory.Exists(wawpath))
{
Properties.Settings.Default.root.Equals(wawpath);
string rootsave = wawpath;
Properties.Settings.Default.root = rootsave;
Properties.Settings.Default.Save();
listBoxAdv1.Visible = true;
root = Properties.Settings.Default.root;
buttonX2.Visible = true;
elf.newlistbox();
elf.listboxfunction();
updatesettings();
}
}
else
{
MessageBox.Show("we did not hit it");
}
}

the methord i want to reach in form1

public void updatesettings()
{
mods = Properties.Settings.Default.mods + "//maps//_zombiemode_weapons.gsc";
dlc3code = Properties.Settings.Default.mods + "//maps//dlc3_code.gsc";
zombiemodeweapons = Properties.Settings.Default.mods + "//maps//_zombiemode_weapons.gsc";
}

and what im trying to do is get gscadder to revrence form 1 to update string paths as follows here

gscadding
and i want here to revrence updatesettings in form1

public SoundAlis sounds;
public addingweapons dlc3gsc;
public Form1 elfygsc;
public gscadding(addingweapons dlc3)
{
dlc3gsc = dlc3;
}
public gscadding(Form1 elfygsc,addingweapons dlc3)
{
this.elfygsc = elfygsc;
}
///
/// MODEL 1887 DLC3....
///
public void dlcexists()
{
elfygsc.updatesettings();
if (dlc3gsc.Model1887 == true)
{
if (File.Exists(dlc3code))
{
MessageBox.Show("exists");
}
else
{
DialogResult dialogResult = MessageBox.Show("Dlc3code.gsc is not found in mods do you wish to copy.", "Dlc3_code.gsc not found in mods", MessageBoxButtons.YesNo);
if (dialogResult == DialogResult.Yes)
{
File.Copy(Properties.Settings.Default.root + "\\raw\\maps\\dlc3_code.gsc", Properties.Settings.Default.mods + "//maps//dlc3_code.gsc", true);
{
string s = "include_weapon( \"model1887_sp\");"; //string s = "include_weapon( \"hk416_zm\");";
string file = modspath1 + "//maps//dlc3_code.gsc";
List<string> lines = new List<string>(System.IO.File.ReadAllLines(file));
int index = lines.FindLastIndex(item => item.Contains(("include_weapon(")));
if (index != -1)
{
lines.Insert(index + 1, s);//""
}
System.IO.File.WriteAllLines(file, lines);
MessageBox.Show("done");
}
}
else if (dialogResult == DialogResult.No)
{
MessageBox.Show("No Files Copied To Add files to the mystery box you will need to add lines later");
}
}
}

and i do have a call in another class im not sure if this is what is causing it or not but i dont think so as that one revrences the form1 as well

addingweapons.cs

SoundAlis sounds;
gscadding elfgscadd;
public bool M27 { get; set; }
public bool Model1887 { get; set; }
// copying files
private void DirectoryCopy(
string sourceDirName, string destDirName, bool copySubDirs)
{
DirectoryInfo dir = new DirectoryInfo(sourceDirName);
DirectoryInfo[] dirs = dir.GetDirectories();
// If the source directory does not exist, throw an exception.
if (!dir.Exists)
{
throw new DirectoryNotFoundException(
"Source directory does not exist or could not be found: "
+ sourceDirName);
}
// If the destination directory does not exist, create it.
if (!Directory.Exists(destDirName))
{
Directory.CreateDirectory(destDirName);
}
// Get the file contents of the directory to copy.
FileInfo[] files = dir.GetFiles();
foreach (FileInfo file in files)
{
// Create the path to the new copy of the file.
string temppath = Path.Combine(destDirName, file.Name);
// Copy the file.
file.CopyTo(temppath, true);
}
// If copySubDirs is true, copy the subdirectories.
if (copySubDirs)
{
foreach (DirectoryInfo subdir in dirs)
{
// Create the subdirectory.
string temppath = Path.Combine(destDirName, subdir.Name);
// Copy the subdirectories.
DirectoryCopy(subdir.FullName, temppath, copySubDirs);
}
}
}
public addingweapons(DevComponents.DotNetBar.Controls.RichTextBoxEx richtextboxelf)
{
richTextBoxEx1 = richtextboxelf;
// opnwep = new Parser(this);
elfgscadd = new gscadding(this);
sounds = new SoundAlis(this, elfgscadd);
elfgscadd.sounds = sounds;
// textboxes
}

And this is the error i get once i push copy weapons

Thank you in advance Saito

Hi,
Again is a problem
Mismatching arguments see the ctor (gscadding) function , you not overwrite the function like below
public gscadding(addingweapons dlc3,Form1 elfygsc)
{
this.elfygsc = elfygsc;
dlc3gsc = dlc3;
}
add this try again (same step in last reply your image) , still facing problem , send the code , Will fix it

Ok quick question that keeps bothering me and i think is what is causing all this

In the above picture i tried passing in elfygsc and it shows it there but how do i make it so its a valid object and it does not say not valid in this context

i know probs a very noob question still learning little bits when it comes to constructors im really good passing in button calls and stuff to other classes but when i try and do a custom one with out calling a already assigned object i always run into issues like this so was just wondering if someone would be so kind to explain how you can do this without getting a null object issue

p.s sorry to be such a pain thanks for helping saito

HI,
Problem you are not passing the object for this.elfygsc in the addingweapons.cs file
public addingweapons(DevComponents.DotNetBar.Controls.RichTextBoxEx richtextboxelf)
{
richTextBoxEx1 = richtextboxelf; // opnwep = new Parser(this);
elfgscadd = new gscadding(this);
}
where is elfygsc value assigning - I hope here is a problem , that's what you get the object null reference

in the Form1 ctor handling different object , both are different object
elfy1 = new gscadding(this, elf_weap);
elfy1.elfygsc = this;

it calls on addingweapons.cs before it goes to adding addinggsc as follows

// adding gsc stuff
public void addinggsc()
{
if (Model1887 == true)
{
elfgscadd.dlcexists();
elfgscadd.addine();
elfgscadd.zombiemodeweaponsexist();
elfgscadd.add_zombie_weapon();
}
if (M27 == true)
{
elfgscadd.dlcexists();
elfgscadd.addine();
elfgscadd.zombiemodeweaponsexist();
elfgscadd.add_zombie_weapon();
}

}

Hi,
Which object are you using to call dlcexists() function and send the callstack of dlcexists() function calling
