Basically I was attempting to use an open file dialog and a list box to list recently opened files in a list box also yes I do use fastcoloredtextbox why do 90% of people I talk to hate it also sorry if the code looks like it was designed by some depressed 11 year old because I am very new.
private void button5_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
string fm = openFileDialog1.FileName;
string rf = File.ReadAllText(fm);
fastColoredTextBox.Text = rf;
string files = Path.GetFileName(fm);
foreach (string file in files)
{
listBox1.Items.Add(file);
}
}
Also it looks unfinished because it is unfinished - I've been trying to fix this and it just kept making more errors so like yea uhh help random people on the internet who I don't know uhh I'm going to stop randomly typing things now
wow edit #3 if it helps anyone I'm having the error on
foreach (string file in files)

First you have to add a new Instance of var openFileDialog = new OpenFileDialog(); if you don't have. Then you could do something like this to get the text of the file and add it to you listbox:
private void button5_Click(object sender, EventArgs e)
{
var openFileDialog = new OpenFileDialog();
if (openFileDialog.ShowDialog() == true)
{
var file = openFileDialog.FileName;
var text = File.ReadAllText(file);
fastColoredTextBox.Text = text;
var filename = Path.GetFileName(file);
listBox1.Items.Add(filename);
}
}
Also you do not have to do this:
foreach (string file in files)
because Path.GetFile() returns only a string with your FileName. So you can add it directly to your ListBox.

I want to make some app and I want the button that when I click i can browse images from file on my computer and then change that image to the form background
I have tried many of code but still can't find one
private void ChangeBackgroundImage_Click(object sender, EventArgs e)
{
//how can I open the browse dialog and choose image file
//and after that, change that image to form backgroundimage?
}
*Im new to this
First, create a button. You will have to use OpenFileDialog to get the file path, after that you can configure the button click by lambda
this.BackgroundImageChanged += new EventHandler((object sender1, EventArgs e1) =>
{
//if the background image has changed
});
OpenFileDialog dialog = new OpenFileDialog();
dialog.Filter = "images|*.png;*.jpeg;*.jpg";
// You can Use "|All Files|*.*" and other to filter the files.
if (dialog.ShowDialog() == DialogResult.OK) //if path picked
{
button1.Click += new EventHandler((object sender1, EventArgs e1) =>
{
string PathFile = dialog.FileName;
this.BackgroundImage = Image.FromFile(PathFile);
});
}
else
{
//if path not picked
}

I'm sure this is really simple to do but I'm struggling.
I've 6 Textboxes and I would like to copy them in Clipboard and paste them to others.
So to copy I do:
private void Btn_Copy_P1_Click(object sender, EventArgs e)
{
StringBuilder cop = new StringBuilder();
cop.AppendLine(X_Point_1_Rob.Text);
cop.AppendLine(Y_Point_1_Rob.Text);
cop.AppendLine(Z_Point_1_Rob.Text);
cop.AppendLine(Rx_Point_1_Rob.Text);
cop.AppendLine(Ry_Point_1_Rob.Text);
cop.AppendLine(Rz_Point_1_Rob.Text);
Clipboard.SetText(sb.ToString());
}
private void Btn_Paste_P2_Click(object sender, EventArgs e)
{
Clipboard.GetText()
// How it's possible to paste the 6 values from Clipboard ?
}
Do you have a working method or a solution?
Something like this, maybe?
private void Btn_Paste_P2_Click(object sender, EventArgs e)
{
string[] text = Clipboard.GetText()?.Split('\\n');
if(text == null || text.Length == 0)
return;
X_Point_1_Rob.Text = text[0];
Y_Point_1_Rob.Text = text[1];
...
Rz_Point_1_Rob.Text = text[5];
}
By the way, where do you want to paste copied snippets of text?
You can try below solution.
// Copy text to the clipboard.
private void btnCopy_Click(object sender, EventArgs e)
{
Clipboard.SetText(txtCopy.Text);
}
// Paste text from the clipboard.
private void btnPaste_Click(object sender, EventArgs e)
{
txtPaste.Text = Clipboard.GetText();
}

I want to do a filtering algorithm with C#, it will be a textbox and I will enter the forbidden words there. If banned words are found in the text I enter in richtextbox later, the word will be deleted as soon as it is written. How can I do this?
private void richTextBox1_TextChanged(object sender, EventArgs e)
{
string[] badWords = textBox1.Text.Split(',');
string[] myText = richTextBox1.Text.Split(',');
foreach (var badWord in badWords)
{
if (myText.Contains(badWord))
{
richTextBox1.Text.Replace(badWord, "");
}
}
}
C# strings are immutable, you need to assign the Text property of your RichTextBox:
if (myText.Contains(badWord))
{
richTextBox1.Text = richTextBox1.Text.Replace(badWord, "");
}

My application prints without showing the PrintDialog (and it need to do so) but I'd like to be able to set to which printer it should print so I added an appsetting in the app.config where it stores the printer name. what I want is a dialog where it shows all printer and the user should be able to choose a printer and it will save in the app.config (I could actually do it from the PrintDialog and get the chosen printer but the button says Print and I don't want to confuse the User...)
Thanks

#methodMan Asked for code so I added My code
System.Windows.Forms.PrintDialog ps = new System.Windows.Forms.PrintDialog();
//set the selected printer in the dialog to the current printer
ps.PrinterSettings.PrinterName = MyApp.Properties.Settings.Default.ContinuesLabelPrinter;
var result = ps.ShowDialog();
if(result == System.Windows.Forms.DialogResult.OK)
{
MyApp.Properties.Settings.Default.ContinuesLabelPrinter = ps.PrinterSettings.PrinterName;
}
OK here is something that will work for you I think...Create a windows Form with a listbox and two buttons.
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
private void Form2_Load(object sender, EventArgs e)
{
foreach (string printer in System.Drawing.Printing.PrinterSettings.InstalledPrinters)
{
listBox1.Items.Add(printer);
}
}
private void button1_Click(object sender, EventArgs e)
{
this.Close();
}
private void button2_Click(object sender, EventArgs e)
{
this.DialogResult = System.Windows.Forms.DialogResult.OK;
}
}
In your code do this:
Form2 form2 = new Form2();
if(form2.Show() == System.Windows.Forms.DialogResult.OK)
{
MyApp.Properties.Settings.Default.ContinuesLabelPrinter = form2.listBox1.SelectedItem.ToString();
}
form2.Dispose(); // <-- this might not be necessary
You will need to make the listBox1 public for this to work.

im trying to create program that changes format of imported images i dont know how to save it any help would be appreciated
--Edit; im trying save each file imported to specific folder with selected format
my code ;
private void button1_Click(object sender, EventArgs e)
{
if (dialog.ShowDialog() == DialogResult.OK)
{
foreach (String file in dialog.FileNames)
{
listView1.Items.Add(System.IO.Path.GetFileNameWithoutExtension(file));
string filee = saveFileDialog1.FileName;
}
}
}
private void Form1_Load(object sender, EventArgs e)
{
}
private void button2_Click(object sender, EventArgs e)
{
foreach (ListViewItem item in listView1.SelectedItems)
{
listView1.Items.Remove(item);
}
}
}
}
var image = System.Drawing.Image.FromFile(inputFilename);
image.Save(outputFileName, System.Drawing.Imaging.ImageFormat.Gif);
That should do it, if I'm not mistaken. You load an image into memory from a file, then save it given whatever format you want, I chose gif here as an example.
