I am making a software that needs to ONLY be able allow people to select files and folders using the OpenFileDialog that are in the same directory as the program and that are in deeper folders. I don't want the OpenFileDialog to be able to select stuff outside of the program's current directory. Is this possible to do in C# using the OpenFileDialog?
Please let me know
Thanks
I don't see any out of the box support by the OpenFileDialog Control. However, you can try the following,
Set the InitialDirectory property to your program path. Then if a user selects a particular path outside of your program path, use the FileOk event to check this and bring him back to the InitialDirectory.
If you want much more control then you will have to write your custom dialog.
This is how I did it.
openFileDialog1.InitialDirectory = Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName");
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
while(Path.GetDirectoryName(openFileDialog1.FileName) != Path.Combine(Path.GetDirectoryName(Application.StartupPath), "FolderName")){
MessageBox.Show("Please select .EXE which is in the default folder", "Wrong folder", MessageBoxButtons.OK, MessageBoxIcon.Information);
openFileDialog1.ShowDialog();
}
}
you can check if the path is correct after selected
if its just accept or send message box tell him you select different directory
I'm afraid you can't. Most people created their own custom dialog for this scenario.

I have some data and I would like to export it to excel. I did all the code, and everything is working fine, Now I want to save that excel file to the hard drive. I could do that too. but my problem is that I couldn't know how to allow the customer to set his/her own file name.
What I have tried:
FolderBrowserDialog brwsr = new FolderBrowserDialog();
//Check to see if the user clicked the cancel button
if (brwsr.ShowDialog() == DialogResult.Cancel)
return;
else
{
string newDirectoryPath = brwsr.SelectedPath;
//Do whatever with the new path
}
the problem of that method is it is just allows the users to select the folder that the want the file to be saved to. I want to all the user to specifiy the path and the file name.
Any idea to help pleaes?
many thanks
You need to use a SaveFileDialog instead. This let's the user specify a path + filename. Check this out for more info: SaveFileDialog on MSDN
SaveFileDialog is pretty similar to FolderBrowserDialog, so you can almost replace the existing code you already have ;)
Specify File Type (EDIT)
Have a look a the Filter property.
Excel files (*.xlsx)|*.xlsx|All files (*.*)|*.*
My program has a treeview which lists files from a remote computer. What I need to do is to copy these files from remote into one of my local folders. I wish that when I right click the file in treeview, a dialog box shows up for me to choose a folder, and then I click "OK" in the dialog box, my clicked file could be saved inside that folder.
Since the path of the files in remote is unc path, I'm using
File.Copy(string remote_address, string local_address)
to copy the files. As i said before I need a dialog window to choose folders. So I've tried using a FolderBowserDialog, however its SelectedPath property returns me only the path to the folder not including the folder's name! And I haven't found any property to return me the folder's name.
So my questions are:
If there's a way allowing me to use FolderBowserDialog, that I could get the full path of the location where I save my file?
If there's another method allowing me to copy or download the files from remote, like using SaveFileDialog. The problem is I don't know how to us it to do this.
The following should work:
var fbd = new FolderBrowserDialog();
if(fbd.ShowDialog() == DialogResult.OK)
{
var localPath= Path.Combine(fbd.SelectedPath, Path.GetFilename(remote_address));
File.Copy(remote_address, localPath);
}
I'm not sure which "SavePath" property you are referring to, as FolderBrowserDialog has no such property. The property you are looking for is called SelectedPath.
FolderBrowserDialog dlg = new FolderBrowserDialog();
dlg.ShowDialog();
string local_address = dlg.SelectedPath;
After you call the FolderBrowserDialog's ShowDialog() method it will return a variable indicating what button the user pressed (ie, Ok or Cancel)
after you make sure the user had used "Ok" to indicate they want to proceed with the operation, you can access the "SelectedPath" field which will give you the full local path they selected.
You can then get the final path by calling
System.IO.Path.Combine(fbd.SelectedPath,remoteFileName);
I'm assuming that fbd is your FolderBrowserDialog instance and remoteFileName should contain just the filename part of the remote file (eg. "MyFile.txt");
If you want to separate the filename from the full remote path, use
var remoteFileName = System.IO.Path.GetFileName(remotePath);
That being said, what a user would typically expect is not a folder browser dialog, but the save file dialog.
you can initialize the save file dialog with a filename, leaving the user to select a folder and possibly change the intended file name as well if they wish.
SaveFileDialog sfd = new SaveFileDialog();
sfd.FileName = remoteFileName;
sfd.ShowDialog();
sfd.FileName // now contains the full path to the file that the user has selected
don't forget to take the result from the ShowDialog() call to make sure the user didn't cancel out of the save dailog!
I think that all i need is in the question. I placed my method in my Form.Load I can either create a folder or open a SaveFileDialog but not both at once.
If someone could help me please.
Thanks.
SaveFileDialog lets the user choose a file location that already exists. If not, they can create a folder within the dialog as #Bali suggested.
If you want the user to be able to create a new folder without using the dialog then you'll need to let the user type the path (e.g. in a textbox). Then you can check to see if the directory exist using Directory.Exist, and if not, create it using Directory.Create.
void CheckPath(string path)
{
var dir = Path.GetDirectoryName(path);
if( !String.IsNullOrEmpty(dir) && !Directory.Exists(dir))
Directory.Create(dir);
}
Open a FolderBrowserDialog for the user with the title (Description property) set to something like "Choose an existing folder or create a new one". Do not forget to set its ShowNewFolderButton property to true.
You can also use the FolderBrowserDialog to ask the user only to select the containing ("parent") folder, and create the new folder yourself by calling Directory.CreateDirectory. In this case, ShowNewFolderButton should be false.
This would be to create a new directory
Directory.CreateDirectory(#"C:\Your File Path Here");
This would be to open a file. You can select where it opens the initial directory of the file by changing the path.
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = (#"C:\Your starting File Path");
openFileDialog1.Filter = "All Files (*.*)|*.*";
openFileDialog1.Title = "Select a File";
I have a customized OpenFileDialog (VS2008, C#, Windows Forms) with a ComboBox. The ComboBox will have a list of paths which the user can select.
My question, is there a way I can change the directory in Open File Dialog to point to the path in the combobox selected item.
InitialDirectory works only before I open the dialog, I wanted a way to change the directory programatically after the dialog is open.
Thanks
If you're using Vista or Windows 7 with .NET 3.5 SP1 I recommend you use the CustomPlaces property on OpenFileDialog rather than a custom combo box.
See this MSDN article (for WPF): http://msdn.microsoft.com/en-us/library/microsoft.win32.filedialog.customplaces(v=VS.100).aspx
Or this MSDN article (for Windows Forms): http://msdn.microsoft.com/en-us/library/system.windows.forms.filedialog.customplaces(v=VS.100).aspx
On Windows 2000 and XP it is also possible to customize the places side bar. But it is more difficult and requires you to use some C++ code (via CLI/C++ is probably best). The technique is described in detail in this MSDN article: http://msdn.microsoft.com/en-us/magazine/cc300434.aspx
If you're dead set on using a combo box you've added to the OpenFileDialog then you will probably just need to know what windows message to send to the dialog. I'm afraid I don't know which message you need to send. The nasty internal Win32 API details of the Common Open/Save dialog is detailed here: http://msdn.microsoft.com/en-us/library/ms646960(VS.85).aspx
If you can figure out which messages to send to the window the probably way of doing things is to fill the filename text field with the directory you want to switch to simulate a OK button click. The dialog will switch to that directory if you do this.
Sending messages to this window will probably require you to not use OpenFileDialog directly but rather subclass the abstract FileDialog class upon which it is based.
Just set the InitialDirectory property of openFileDialog1
private void button1_Click(object sender, System.EventArgs e)
{
Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.InitialDirectory = cmbPath.SelectedValue.ToString();
openFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
openFileDialog1.FilterIndex = 2 ;
openFileDialog1.RestoreDirectory = true ;
if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = openFileDialog1.OpenFile()) != null)
{
using (myStream)
{
// Insert code to read the stream here.
}
}
}
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
}
}
As already said InitialDirectory works before hand but why would you change the folder afterwords? FileOpenDialog is a modal dialog, therefore the user can't use anything else of your application than the dialog. What is the benefit and reason why you wan't to set the folder? It seems your using the wrong tools to get the job done.
What's the best way to let a user pick a subdirectory in C#?
For example, an app that lets the user organize all his saved html receipts. He most likely is going to want to be able to select a root subdirectory that the program should search for saved webpages (receipts).

The Folder Browser Dialog is the way to go.
If you want to set an initial folder path, you can add this to your form load event:
// Sets "My Documents" as the initial folder path
string myDocsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
FolderBrowserDialog1.SelectedPath = myDocsPath;
Check the FolderBrowserDialog class.
// ...
if (folderBrowserDialog1.ShowDialog() == DialogResult.OK)
{
textBox1.Text = folderBrowserDialog1.SelectedPath;
}
FolderBrowserDialog works just fine for this purpose.
FolderBrowserDialog works, but offers very little customization.
If you want a textbox where users can type in the path have a look here

Whatever you do, don't use the FolderBrowserDialog.
Just kidding. Use that.
