Cant copy a png image in c#

I am creating an app that i need to copy some png files.
I already have searching with many keywords, finding many solutions and none of them worked, so i decided to ask here.
There is the code,it uses a windows forms and "this" refers to this window
private void button2_Click(object sender, EventArgs e)
{
//yes i commented them to solve why the file was not copying
//try
{
FileInfo x = new FileInfo(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\some_location");
x.CopyTo(textBox1.Text);
}
//catch
{ }
this.Close();
}
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog openDialog = new OpenFileDialog();
openDialog.Title = "Select Image To Load";
openDialog.Filter = "Text Files (*.png)|*.png" + "|" + "All Files (*.*)|*.*";
if (openDialog.ShowDialog() == DialogResult.OK)
{
string PathData = openDialog.FileName;
textBox1.Text = PathData;
}
}
I have gotten several different errors, but most common there is:
System.UnauthorizedAccessException

It looks a bit weird to me that you're using an OpenFileDialog to select a destination. I'd assume you'd want to either do it the other way around:
private void button2_Click(object sender, EventArgs e)
{
//yes i commented them to solve why the file was not copying
//try
{
FileInfo x = new FileInfo(textBox1.Text);
x.CopyTo(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + #"\some_location");
}
//catch
{ }
this.Close();
}
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog openDialog = new OpenFileDialog();
openDialog.Title = "Select Image To Load";
openDialog.Filter = "Text Files (*.png)|*.png" + "|" + "All Files (*.*)|*.*";
if (openDialog.ShowDialog() == DialogResult.OK)
{
string PathData = openDialog.FileName;
textBox1.Text = PathData;
}
}
or use SaveFileDialog instead.

Folder Browser Dialog with Environment

I created an app for my dad. It's just a simple dictation program. The thing is when he installed it on his computer it stalled and said the general access denied error.
The first time it gave the error I used SaveFileDialog sfd = new SaveFileDialog() then added the usually 'if statement" to make sure the dialog was ok. However the app had an access file denied.
I did the same thing with Environment.GetFolder and it installed on his computer to the location and ran fine. However, when I use the saveFileDialog1 and openFileDialog1 out of the tool box it does not save or open a txt document.
It works on my laptop and not his. Could this be due to an error in the code vs his computer. Also what is the correct way to use the Environement.GetFolder with the SaveFileDialog.
I can also post the full code to the program if needed.
private void lblOpenFile_Click(object sender, EventArgs e)
{
OpenFileDialog open = new OpenFileDialog();
open.Title = "Open File";
open.Filter = "Text Files (*txt) | *.txt";
if (open.ShowDialog() == DialogResult.OK)
{
StreamReader read = new StreamReader(File.OpenRead(open.FileName));
txtTextBox.Text = read.ReadToEnd();
read.Dispose();
}
}
private void lblSaveFile_Click(object sender, EventArgs e)
{
SaveFileDialog save = new SaveFileDialog();
save.Title = "Save File";
save.Filter = "Text Files (*txt) | *.txt";
if (save.ShowDialog() == DialogResult.OK)
{
StreamWriter write = new StreamWriter(File.Create(save.FileName));
write.Write(txtTextBox.Text);
write.Dispose();
}
}
This is the Enviroment i used on my screen recorder. i when i click save it brings up a dialog box i put in the file name press save and it does nothing. It saves the file but not as i specified. So i am trying to merge the above and below codes. The above code does not grant access however the below does
string OutputPath;
OutputPath = Environment.GetFolderPath(Environment.SpecialFolder.MyVideos) + #"\\IvanSoft Desktop Recorder" + saveFileDialog1;
private void saveFileDialog1_FileOk(object sender, CancelEventArgs e)
{
string fileName = saveFileDialog1.FileName;
fileName = "Tutorial";
}

It's hard to say where you're failing, because there isn't much in the way of try/catch or logging.
Can you use this instead, and paste the stack trace that shows in the Message Box?
private string fileOutputLocation { get; set; }
private void lblSaveFile_Click(object sender, EventArgs e)
{
bool fileSelected = false;
Try(() =>
{
SaveFileDialog save = new SaveFileDialog();
save.Title = "Save File";
save.Filter = "Text Files (*txt) | *.txt";
save.InitialDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "IvanSoft Desktop Recorder");
if (save.ShowDialog() == DialogResult.OK)
{
fileOutputLocation = save.FileName;
fileSelected = true;
}
});
if (fileSelected)
{
bool fileSaved = SaveFile();
MessageBox.Show("File saved successfully: " + fileSaved.ToString());
}
}
private bool SaveFile()
{
TryDeleteFile();
bool fileSaved = false;
Try(()=>
{
File.WriteAllText(fileOutputLocation, txtTextBox.Text);
fileSaved = true;
});
return fileSaved;
}
private void TryDeleteFile()
{
Try(()=>
{
if (File.Exists(fileOutputLocation))
{
File.Delete(fileOutputLocation);
}
});
}
private void Try(Action action)
{
try
{
action();
}
catch (Exception e)
{
MessageBox.Show(string.Format("The following exception was thrown:\r\n{0}\r\n\r\nFile path: {1}", e.ToString(), fileOutputLocation));
}
}
With this, plus the events logged to the Windows Event Viewer (Start>Run>Eventvwr>Security), we should be able to tell you what the problem is.
Lastly, if you're just providing an executable to run, you should check the properties of the file to ensure it's not blocked in Windows.

SaveFileDialog Error

I'm trying to make a simple Windows Form Application that saves a text file. I'm having trouble with the following program, it gives me:
Empty path is not a legal
namespace Filing
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button_Save_Click(object sender, EventArgs e)
{
SaveFileDialog file = new SaveFileDialog();
file.Filter = "Text (*.txt) | Word File *.doc";
file.Title = "Save a file";
File.WriteAllText(file.FileName, richTextBox1.Text);
file.ShowDialog();
}
private void button_exit_Click(object sender, EventArgs e)
{
this.Close();
}
}
}

Cause you didn't "show" the SaveFileDialog yet, so the fileName is empty.
Try moving the showDialog upward:
private void button_Save_Click(object sender, EventArgs e)
{
SaveFileDialog file = new SaveFileDialog();
file.Filter = "Text (*.txt) | Word File *.doc";
file.Title = "Save a file";
//Ask the user to select the file path and file name, don't forget to handle cancel button!
if(file.ShowDialog() != DialogResult.Cancel)
{
File.WriteAllText(file.FileName, richTextBox1.Text);
}
}

You should wrap the writing statement as the following.
if(file.ShowDialog()== DialogResult.OK)
File.WriteAllText(file.FileName, richTextBox1.Text);

Process start from two strings

I am trying to open a file which a user can set. In other words it will never be a set path or file. so when the user has selected the file they want to open this button below will open it. I have declared l1 and p1 as public strings.
public void button4_Click(object sender, EventArgs e)
{
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK)
{
l1 = Path.GetFileName(openFileDialog1.FileName);
p1 = System.IO.Path.GetDirectoryName(openFileDialog1.FileName);
}
public void button2_Click(object sender, EventArgs e)
{
//p1 = directory path for example "C:\\documents and settings\documents"
//l1 = filename
Process.Start(p1+l1);
}
So just to review I want to open up the file just using the directory path and filename. Is this possible? I can just have p1 there and it will open an explorer showing me that directory. Thank you for looking.

Yes it will work, but I would recommend you update your code this instead:
var path = Path.Combine(p1, l1);
Process.Start(path);

You shouldn't use string concatenation to combine a directory and filename. In your case the resulting string will look like this:
C:\documents and settings\documentsfilename
^^
this is wrong
Instead use Path.Combine.
string path = Path.Combine(p1, l1);
Process.Start(path);

Why don't you simply do this: -
public void button4_Click(object sender, EventArgs e)
{
string fileNameWithPath;
DialogResult result = openFileDialog1.ShowDialog();
if (result == DialogResult.OK)
{
fileNameWithPath = openFileDialog1.FileName;
}
}
public void button2_Click(object sender, EventArgs e)
{
Process.Start(fileNameWithPath);
}

Fill Text Forms AND Clickable text forms In C#

I have a windows form application I have a button that opens the SaveFileFrom dialog
private void button1_Click(object sender, EventArgs e)
{
SaveFileDialog savefileDialog1 = new SaveFileDialog();
savefileDialog1.ShowDialog();
}
I was wondering how I could put the file that is chosen in a text box even like so
private void textBox1_TextChanged(object sender, EventArgs e)
{
}
UPDATE* Ok, well since the user might want to open more than one file to save I wanted to take off my button SaveFileFrom and instead make the textbox run through the OpenFileDialog when clicked.
Also, is their a way to make a text link instead of a button?
Like I want a text link to add another text box/

Try this
private void button1_Click(object sender, EventArgs e)
{
SaveFileDialog savefileDialog1 = new SaveFileDialog();
if (savefileDialog1.ShowDialog() == DialogResult.OK)
{
textBox1.Text = savefileDialog1.Filename;
}
}

The filename selected will be saved in SaveFileDialog.FileName
example:
private void button1_Click(object sender, EventArgs e)
{
SaveFileDialog SvDlg = new SaveFileDialog();
if (SvDlg.ShowDialog() == DialogResult.OK)
{
textBox1.Text = SvDlg.FileName;
}
else
{
MessageBox.Show("No file selected.");
}
}
