Multiple filters OpenFileDialog - c#

At the moment I have three buttons on a form, each opens a different form (form2 with a textbox to display the text from the textfile, form3 with a picturebox to display the image)
What I am trying to do is put the two together for my last button so the user can filter which type to open (TXT Files or Image files). I am not sure how I can put the two together and get them to work.
The code I used to just open text files:
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.InitialDirectory = #"C:\";
ofd.Filter = "TXT Files(*.txt;)|*.txt;";
if(ofd.ShowDialog() == DialogResult.OK)
{
using(StreamReader rdText = new StreamReader(ofd.FileName))
{
string info = File.ReadAllText(ofd.FileName);
TextDocumentForm newTextDocument = new TextDocumentForm();
newTextDocument.TextFileName = info;
newTextDocument.Show();
}
}
}
What I use to open my image files
private void button2_Click(object sender, EventArgs e)
{
OpenFileDialog ofdi = new OpenFileDialog();
ofdi.InitialDirectory = #"C:\";
ofdi.Filter = "Image Files(*.jpg;*.jpeg;*.bmp)|*.jpg;*.jpeg;.bmp;";
if (ofdi.ShowDialog() == DialogResult.OK)
{
Image image = Image.FromFile(ofdi.FileName);
ImgDoc newImageDoc = new ImgDocumentForm();
newImageDoc.ImageShow = image;
newImageDoc.Show();
}
}
Any help is appreciated as I am trying to develop my understanding of how OpenFileDialog still works.

Combining filters:
var openFile = new OpenFileDialog
{
InitialDirectory = #"C:\",
Filter = "TXT Files(*.txt;)|*.txt;|Image Files(*.jpg;*.jpeg;*.bmp)|*.jpg;*.jpeg;.bmp;"
};
Then use Path.GetExtension() to see which route you should take:
if (openFile.ShowDialog() == true)
{
var ext = System.IO.Path.GetExtension(openFile.FileName);
if (ext == ".txt")
{
// Open text file
}
else if (ext == ".jpg" || ext == ".jpeg" || ext == ".bmp")
{
// Open image file
}
}

how to access OpenFileDialog with Streamwrite?

i want to make a windows forms app with 2 buttons
1 Button to find a .wtf or .txt file
Second Button to write a line into selected file let`s say "example"
this is my first button
private void button5_Click_1(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = false;
if (choofdlog.ShowDialog() == DialogResult.OK)
{
string sFileName = choofdlog.FileName;
}
}
now how do i make the second button write "example" into the file i selected with the first one ?
You can achieve this in two steps:
First, you have to store the file name in a member variable:
private string _fileName;
private void button5_Click_1(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = false;
if (choofdlog.ShowDialog() == DialogResult.OK)
{
_fileName = choofdlog.FileName;
}
}
In the second step, you have to define the logic of button 2:
private void secondButton_Click_1(object sender, EventArgs e)
{
System.IO.File.WriteAllText( _fileName, "Example" );
}
"1 Button to find a .wtf or .txt file"
To look for specific file extensions you should change your filter a bit
openFileDialog.InitialDirectory = "c:\\";
openFileDialog.Filter = "txt files (*.txt)|*.txt|wtf files (*.wtf)|*.wtf";
openFileDialog.FilterIndex = 2;
openFileDialog.RestoreDirectory = true;

Converting image with OpenfileDialog

I need help with this code. I want to create basic image convert program but this program is not working? What am I doing wrong. Thanks for answers.
private void button1_Click(object sender, EventArgs e)
{
OpenFileDialog file = new OpenFileDialog();
file.ShowDialog();
string DosyaYolu = file.FileName;
string DosyaAdi = file.SafeFileName;
if (file.ShowDialog() == DialogResult.OK)
{
System.Drawing.Image image = System.Drawing.Image.FromFile(DosyaYolu);
image.Save(DosyaYolu, System.Drawing.Imaging.ImageFormat.Png);
}
You choose the wrong target path to save the new image to. Also you invoked the ShowDialog() twice, which is not necessary. The following code will save the new file with the same name but a different extension.
var dialog = new OpenFileDialog();
if (dialog.ShowDialog() == DialogResult.OK)
{
string sourceFile = dialog.FileName;
string targetFile = Path.ChangeExtension(sourceFile, "png");
Image image = Image.FromFile(sourceFile);
image.Save(targetFile, ImageFormat.Png);
}

C# Load .txt file and show in listview

so what I'm trying to do is load a .txt file and once the .txt file is loaded it will show the contents from the .txt file in a listView.
Here is my load code.
List<String> proxies = new List<string>();
private void loadProxiesToolStripMenuItem_Click(object sender, EventArgs e)
{
loadProxies();
}
private void loadProxies()
{
this.Invoke(new MethodInvoker(delegate
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "TXT files|*.txt";
ofd.Title = "Load Proxies";
var dialogResult = ofd.ShowDialog();
if (dialogResult == DialogResult.OK)
{
proxies = new List<string>();
Parallel.ForEach(System.IO.File.ReadLines(ofd.FileName), (line, _, lineNumber) =>
{
if (line.Contains(":"))
{
//loadedCombo.Add(line);
proxies.Add(line);
}
else
{
//MessageBox.Show("Hmm, thats not a combolist - please try again");
}
});
}
txt_proxies.Text = "Proxies Loaded: " + proxies.Count.ToString();
}));
}
and I'm wanting it to show in the listView which is named "proxyView".
So what I'm trying to say it, I can get the .txt to load and it changes the count but it's not adding the contents from the .txt file into the listview.
Thanks much appreciated.
To add an item to a ListView you can use yourListView.Items.Add(text)
For example:
private void loadProxies()
{
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "TXT files|*.txt";
ofd.Title = "Load Proxies";
var dialogResult = ofd.ShowDialog();
if (dialogResult == DialogResult.OK)
{
foreach (var line in System.IO.File.ReadLines(ofd.FileName))
{
if (line.Contains(":"))
proxyView.Items.Add(line);
}
}
}

How to get file path from OpenFileDialog and FolderBrowserDialog?

Hey there i started learning C# a few days ago and I'm trying to make a program that copies and pastes files (and replaces if needed) to a selected directory but I don't know how to get the directory and file paths from the openfiledialog and folderbrowserdialog
what am I doing wrong?
Here's the code:
namespace filereplacer
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void direc_Click(object sender, EventArgs e)
{
string folderPath = "";
FolderBrowserDialog directchoosedlg = new FolderBrowserDialog();
if (directchoosedlg.ShowDialog() == DialogResult.OK)
{
folderPath = directchoosedlg.SelectedPath;
}
}
private void choof_Click(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
choofdlog.ShowDialog();
}
private void replacebtn_Click(object sender, EventArgs e)
{
// This is where i'm having trouble
}
public static void ReplaceFile(string FileToMoveAndDelete, string FileToReplace, string BackupOfFileToReplace)
{
File.Replace(FileToMoveAndDelete, FileToReplace, BackupOfFileToReplace, false);
}
}
For OpenFileDialog:
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
if (choofdlog.ShowDialog() == DialogResult.OK)
{
string sFileName = choofdlog.FileName;
string[] arrAllFiles = choofdlog.FileNames; //used when Multiselect = true
}
For FolderBrowserDialog:
FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.Description = "Custom Description";
if (fbd.ShowDialog() == DialogResult.OK)
{
string sSelectedPath = fbd.SelectedPath;
}
To access selected folder and selected file name you can declare both string at class level.
namespace filereplacer
{
public partial class Form1 : Form
{
string sSelectedFile;
string sSelectedFolder;
public Form1()
{
InitializeComponent();
}
private void direc_Click(object sender, EventArgs e)
{
FolderBrowserDialog fbd = new FolderBrowserDialog();
//fbd.Description = "Custom Description"; //not mandatory
if (fbd.ShowDialog() == DialogResult.OK)
sSelectedFolder = fbd.SelectedPath;
else
sSelectedFolder = string.Empty;
}
private void choof_Click(object sender, EventArgs e)
{
OpenFileDialog choofdlog = new OpenFileDialog();
choofdlog.Filter = "All Files (*.*)|*.*";
choofdlog.FilterIndex = 1;
choofdlog.Multiselect = true;
if (choofdlog.ShowDialog() == DialogResult.OK)
sSelectedFile = choofdlog.FileName;
else
sSelectedFile = string.Empty;
}
private void replacebtn_Click(object sender, EventArgs e)
{
if(sSelectedFolder != string.Empty && sSelectedFile != string.Empty)
{
//use selected folder path and file path
}
}
....
}
NOTE:
As you have kept choofdlog.Multiselect=true;, that means in the OpenFileDialog() you are able to select multiple files (by pressing ctrl key and left mouse click for selection).
In that case you could get all selected files in string[]:
At Class Level:
string[] arrAllFiles;
Locate this line (when Multiselect=true this line gives first file only):
sSelectedFile = choofdlog.FileName;
To get all files use this:
arrAllFiles = choofdlog.FileNames; //this line gives array of all selected files
Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.
Usage is simple.
string directoryPath = System.IO.Path.GetDirectoryName(choofdlog.FileName);
you can store the Path into string variable like
string s = choofdlog.FileName;
To get the full file path of a selected file or files, then you need to use FileName property for one file or FileNames property for multiple files.
var file = choofdlog.FileName; // for one file
or for multiple files
var files = choofdlog.FileNames; // for multiple files.
To get the directory of the file, you can use Path.GetDirectoryName
Here is Jon Keet's answer to a similar question about getting directories from path
Create this class as Extension:
public static class Extensiones
{
public static string FolderName(this OpenFileDialog ofd)
{
string resp = "";
resp = ofd.FileName.Substring(0, 3);
var final = ofd.FileName.Substring(3);
var info = final.Split('\\');
for (int i = 0; i < info.Length - 1; i++)
{
resp += info[i] + "\\";
}
return resp;
}
}
Then, you could use in this way:
//ofdSource is an OpenFileDialog
if (ofdSource.ShowDialog(this) == DialogResult.OK)
{
MessageBox.Show(ofdSource.FolderName());
}
Your choofdlog holds a FileName and FileNames (for multi-selection) containing the file paths, after the ShowDialog() returns.
A primitive quick fix that works.
If you only use OpenFileDialog, you can capture the FileName, SafeFileName, then subtract to get folder path:
exampleFileName = ofd.SafeFileName;
exampleFileNameFull = ofd.FileName;
exampleFileNameFolder = ofd.FileNameFull.Replace(ofd.FileName, "");
I am sorry if i am late to reply here but i just thought i should throw in a much simpler solution for the OpenDialog.
OpenDialog ofd = new OpenDialog();
var fullPathIncludingFileName = ofd.Filename; //returns the full path including the filename
var fullPathExcludingFileName = ofd.Filename.Replace(ofd.SafeFileName, "");//will remove the filename from the full path
I have not yet used a FolderBrowserDialog before so i will trust my fellow coders's take on this. I hope this helps.
String fn = openFileDialog1.SafeFileName;
String path = openFileDialog1.FileName.ToString().Replace(fn, "");

How do you use an specific file from a C# multiselection dialog?

I need to use an specific file from the ones you select from a file dialog.
OpenFileDialog ofd = new OpenFileDialog();
private void pictureBox23_Click(object sender, EventArgs e)
{
ofd.Filter = "WAV|*.wav";
this.ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
{
label23.Text = ofd.SafeFileName;
}
else
{
label23.Text = "No files selected...";
}
}
What i need to do is select and use the files I pre-define, so if I define an event with 01.wav if the user selects a file named 01.wav, that one will be used like so:
using (SoundPlayer player = new SoundPlayer(Beatpadpc.Properties.Resources._01))
{
player.Play();
}
I currently have it adapted as it will play it from the resources, what i need to do is to play the file from the file selecion, but only if the file is named "01".wav
Is there a way for doing it?
Well, just filter the ofd property called Filenames.
OpenFileDialog ofd = new OpenFileDialog();
string strAudioFilePath = String.Empty;
private void pictureBox23_Click(object sender, EventArgs e)
{
ofd.Filter = "WAV|*.wav";
this.ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
{
// Here you make a small filter with linq
label23.Text = strAudioFilePath = ofd.FileNames.FirstOrDefault(x => x.EndsWith("01.wav")); // you change 01.wav to something that make more sense to you
}
else
{
label23.Text = "No files selected...";
}
}
Then if you want to get rid of your resource file, just give your sound player the path of the file and that's all.
SoundPlayer simpleSound = new SoundPlayer(strAudioFilePath);
simpleSound.Play();
