Create a 7zip file for every subdirectory to a output path from input path in winforms

I have an input path that contains an unknown number of
subdirectories.
I want to use 7zip to zip each of them and the zip file will be in the selected output path.
Below is the concept of this program.
Below is the 7zip code I try to achieve the result, but no idea how to do.
string source = textBoxInput.Text + "\\*";
string target = Path.Combine(tBoxOutput.Text, source + DateTime.Now.ToString());
foreach (var folder in Directory.GetDirectories(source))
{
_sevenZip.CreateZipFile(folder, target);
}
Below is the 7z in command line I use to this program.
try
{
ProcessStartInfo zipProcess = new ProcessStartInfo();
zipProcess.FileName = #"E:\Program Files\7-Zip\7z.exe";
zipProcess.Arguments = "a -t7z \"" + targetName + "\" \"" + sourceName + "\" -mx=9";
zipProcess.WindowStyle = ProcessWindowStyle.Minimized;
Process zip = Process.Start(zipProcess);
zip.WaitForExit();
}
catch (Exception err)
{
Console.WriteLine(err.Message);
}

I remember helping you once with that question , i guess my answer was not to your satisfaction,
I've tried better this time:
this is the window:
these are the folders I used, just like in your example:
'choose source' and 'choose target' button opens a folder dialog
you were in the right direction, a for loop that runs over the subdirectories. i guess the hard part was getting the correct names. you just need to make sure that the target name would have a ".7z" extension.
and the code is fairly simple:
string zipProgramPath = #"C:\Program Files\7-Zip\7z.exe";
public Form1()
{
InitializeComponent();
}
public void CreateZipFile(string sourceName, string targetName)
{
try
{
ProcessStartInfo zipProcess = new ProcessStartInfo();
zipProcess.FileName = zipProgramPath; // select the 7zip program to start
zipProcess.Arguments = "a -t7z \"" + targetName + "\" \"" + sourceName + "\" -mx=9";
zipProcess.WindowStyle = ProcessWindowStyle.Minimized;
zipProcess.UseShellExecute = true;
Process zip = Process.Start(zipProcess);
zip.WaitForExit();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
private void btnBrowseSource_Click(object sender, EventArgs e)
{
using (var fbd = new FolderBrowserDialog())
{
DialogResult result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath))
{
lblSource.Text = fbd.SelectedPath; //label next to the button
}
}
}
private void btnBrowseTarget_Click(object sender, EventArgs e)
{
using (var fbd = new FolderBrowserDialog())
{
DialogResult result = fbd.ShowDialog();
if (result == DialogResult.OK && !string.IsNullOrWhiteSpace(fbd.SelectedPath))
{
lblTarget.Text = fbd.SelectedPath.ToString(); //label next to the button
}
}
}
private void btnExecute_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(lblSource.Text) || string.IsNullOrEmpty(lblTarget.Text))
{
MessageBox.Show("Choose input directory and output directory");
}
else
{
foreach (var folder in Directory.GetDirectories(lblSource.Text))
{
string folderName= Path.GetFileName(folder);
string targetName = Path.Combine(lblTarget.Text, folderName+ ".7z" );
CreateZipFile(folder, targetName);
}
}
}
so after choosing the right directories, and pressing execute
the result is as required :

Here is the PowerShell script will do the same. SourceFolders will have your test, test1, test2 folders. Compressed files will gets stored into C:\DestinationFolder. You just have run this script from PowerShell command prompt.
Import-Module Microsoft.PowerShell.Management
$sourcefolders = Get-ChildItem "C:\SourceFolders"
$outputfolder = "C:\DestinationFolder"
for ($i=0; $i -lt $sourcefolders.Count; $i++) {
$folderPathToCompress = $sourcefolders[$i].FullName
$compressFileName = $sourcefolders[$i].Name
"Compressing folder ="+$folderPathToCompress;
.\7z a -t7z $outputfolder\$compressFileName".7z" $folderPathToCompress
}

Issue with output location when saving file

Currently having an issue when saving a merged word. doc to a specific location using a filebrowser dialog
// input destintion
private string[] sourceFiles;
private void browseButton_Click(object sender, EventArgs e)
{
FolderBrowserDialog diagBrowser = new FolderBrowserDialog();
diagBrowser.Description = "Select a folder which contains files needing combined...";
// Default folder, altered when the user selects folder of choice
string selectedFolder = #"";
diagBrowser.SelectedPath = selectedFolder;
// initial file path display
folderPath.Text = diagBrowser.SelectedPath;
if (DialogResult.OK == diagBrowser.ShowDialog())
{
// Grab the folder that was chosen
selectedFolder = diagBrowser.SelectedPath;
folderPath.Text = diagBrowser.SelectedPath;
sourceFiles = Directory.GetFiles(selectedFolder, "*.doc");
}
}
// output destintion
private string[] sourceFileOutput;
private void browseButtonOut_Click(object sender, EventArgs e)
{
FolderBrowserDialog diagBrowserOutput = new FolderBrowserDialog();
diagBrowserOutput.Description = "Select a folder location to save the document...";
// Default folder, altered when the user selects folder of choice
string outputFolder = #"";
diagBrowserOutput.SelectedPath = outputFolder;
// output file path display
outputPath.Text = diagBrowserOutput.SelectedPath;
if (DialogResult.OK == diagBrowserOutput.ShowDialog())
{
outputFolder = diagBrowserOutput.SelectedPath;
outputPath.Text = diagBrowserOutput.SelectedPath;
sourceFileOutput = Directory.GetFiles(outputFolder);
}
}
private void combineButton_Click(object sender, EventArgs e)
{
if (sourceFiles != null && sourceFiles.Length > 0)
{
string outputFileName = (sourceFileOutput + "Combined.docx");
MsWord.Merge(sourceFiles, outputFileName, true);
// Message displaying how many files are combined.
MessageBox.Show("A total of " + sourceFiles.Length.ToString() + " documents have been merged", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
// Message displaying error.
MessageBox.Show("Please a select a relevant folder with documents to combine", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
instead of getting the 'combined.docx' in the location chosen, i instead get a file called 'System.String[]Combined' saved on the desktop. Obviously there is something clashing regarding the name and the user selected file path.
i currently have the input folder options working however the output + file name doesn't seem to be working correctly.
any suggestions or help would be greatly appreciated, thank you.

string outputFileName = (sourceFileOutput + "Combined.docx");
This should probably read
string outputFileName = selectedFolder + "Combined.docx";
That said, please use Path.Combine to combine two parts of a path.

got the program to use the 'selected' destination.
// output destintion
string outputFolder = #"";
private void browseButtonOut_Click(object sender, EventArgs e)
{
FolderBrowserDialog diagBrowserOutput = new FolderBrowserDialog();
diagBrowserOutput.Description = "Select a folder location to save the document...";
// Default folder, altered when the user selects folder of choice
diagBrowserOutput.SelectedPath = outputFolder;
// output file path display
outputPath.Text = diagBrowserOutput.SelectedPath;
if (DialogResult.OK == diagBrowserOutput.ShowDialog())
{
outputFolder = diagBrowserOutput.SelectedPath;
outputPath.Text = diagBrowserOutput.SelectedPath;
}
}
private void combineButton_Click(object sender, EventArgs e)
{
if (sourceFiles != null && sourceFiles.Length > 0)
{
string folderFolder = outputFolder;
string outputFile = "Combined.docx";
string outputFileName = Path.Combine(folderFolder, outputFile);
MsWord.Merge(sourceFiles, outputFileName, true);
// Message displaying how many files are combined.
MessageBox.Show("A total of " + sourceFiles.Length.ToString() + " documents have been merged", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
i used the path.combine as suggested, as played around with the variables i had used.

Error : A generic error occurred in GDI+. while saving Image

While i am trying to save Image getting this error
A generic error occurred in GDI+
I searched for this error and checked write permissions for this folder ,and also checked that image file is not in use by anything else (including my code) But While I am trying to save Image still getting same error,Where is the mistake
public partial class AdsMaster : Form
{
OpenFileDialog ofd=null;
public AdsMaster()
{
InitializeComponent();
}
private void browseButton_Click(object sender, EventArgs e)
{
ofd = new OpenFileDialog();
ofd.Filter = "image files|*.jpg;*.jpeg;*.gif;*.png;*.bmp";
DialogResult dr = new DialogResult();
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Image img = new Bitmap(ofd.FileName);//create the bitmap
string imgName = ofd.SafeFileName;
txtImagePath.Text = imgName;
pictureBox1.Image = img.GetThumbnailImage(350, 350, null, new IntPtr());
ofd.RestoreDirectory = true;
img.Dispose();
}
}
private void saveImage_Click(object sender, EventArgs e)
{
String str = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
string path = str + "\\Image\\";
Image img = new Bitmap(ofd.FileName);
string imgName = ofd.SafeFileName;
try
{
img.Save(path + imgName); //getting error at this line
MessageBox.Show("Image is saved");
img.Dispose(); // dispose of your image
}
catch(Exception err)
{
MessageBox.Show(err.Message.ToString());
}
}
}

I think the problem here may be due to the fact that a lock is placed on the original image when you call
Image img = new Bitmap(ofd.FileName);
The following should do the trick
private void saveImage_Click(object sender, EventArgs e)
{
string str = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);
string path = str + "\\Image\\";
string imgName = ofd.SafeFileName;
try
{
File.Copy(ofd.FileName, path + imgName);
MessageBox.Show("Image is saved");
}
catch (Exception err)
{
MessageBox.Show(err.Message.ToString());
}
}

I resolve this error by changing the file name and path to where the file is stored.
You needs to check either one of them-
1- FileName should be different/ should not get matched with other files name which have been already present on that location where new file/image you want to store.
2- change the (save ) location of the new file from operating system drive.
try to avoid to store the new file/Image on a drive on which operating system has been already installed.
Below code works for me
IWebdriver driver;
driver = new ChromeDriver("G:\\Selenium_Csharp\\Jar\\chromedriver_win32");
driver.Navigate().GoToUrl("http://www.gmail.com");
driver.Manage().Window.Maximize();
Screenshot ss = ((ITakesScreenshot)driver).GetScreenshot();
ss.SaveAsFile("e:\\pande", System.Drawing.Imaging.ImageFormat.Jpeg);

Can't access file

I can't seem to get access to the file I'm working with in the program I'm writing. I'm not sure how exactly to work this since I want my program to open a file of your choice, which it does, then I want it to be able to take in info into an arrary, which it does, then from there, write that information from the array to the file you opened up. When I try some code to start working on it it tells me, "The process cannot access the file 'file' because it is being used by another process." Here is what I have so far. Please let me know. Thank you. The problematic areas is the Save_Click section of the code where I wrote "This is a test" Thanks.

}
}

You get error here
File.ReadAllText(fileName)
because you open same file before it here
System.IO.StreamReader file = new System.IO.StreamReader(fileName);

You need to close the file after you are finished reading it. Also, not sure why you are opening the file at all, since you subsequently use File.ReadAllText which will handle opening and closing the file all on its own.
Seems like your OpenFile_click event should just look like this:
using (OpenFileDialog filechooser = new OpenFileDialog())
{
result = filechooser.ShowDialog();
fileName = filechooser.FileName;
string[] words = File.ReadAllText(fileName).Split(new string[] { "\n", "\r\n", ":" }, StringSplitOptions.RemoveEmptyEntries);
Read.Enabled = true;
}

You haven't closed your StreamReader. C# will lock the file until you do. Or you could use a StreamWriter after you closed your StreamReader

C# Windows Forms - Select and Copy Multiple Files w MultiSelect, OpenFileDialog, & FileBrowserDialog

I'm developing a WinForms application using C# with an OpenFileDialog and FileBrowserDialog and I'd like to:
Enable selection of multiple xls files.
After selection is made, Display selected xlsx filenames in textbox
Copy the selected files to a separate directory Consolidated
How can I accomplish this?

Here is sample code:
OpenFileDialog od = new OpenFileDialog();
od.Filter = "XLS files|*.xls";
od.Multiselect = true;
if (od.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string tempFolder = System.IO.Path.GetTempPath();
foreach (string fileName in od.FileNames)
{
System.IO.File.Copy(fileName, tempFolder + #"\" + System.IO.Path.GetFileName(fileName));
}
}

There is MultiSelect property of OpenFileDialog which you need to set to true to allow selecting multiple files.
Here is a code example from MSDN which allows the user to select a multiple number of images and display them in PictureBox controls on a Form:
private void Form1_Load(object sender, EventArgs e)
{
InitializeOpenFileDialog();
}
private void InitializeOpenFileDialog()
{
// Set the file dialog to filter for graphics files.
this.openFileDialog1.Filter =
"Images (*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|" +
"All files (*.*)|*.*";
// Allow the user to select multiple images.
this.openFileDialog1.Multiselect = true;
this.openFileDialog1.Title = "My Image Browser";
}
private void selectFilesButton_Click(object sender, EventArgs e)
{
DialogResult dr = this.openFileDialog1.ShowDialog();
if (dr == System.Windows.Forms.DialogResult.OK)
{
// Read the files
foreach (String file in openFileDialog1.FileNames)
{
// Create a PictureBox.
try
{
PictureBox pb = new PictureBox();
Image loadedImage = Image.FromFile(file);
pb.Height = loadedImage.Height;
pb.Width = loadedImage.Width;
pb.Image = loadedImage;
flowLayoutPanel1.Controls.Add(pb);
}
catch (SecurityException ex)
{
// The user lacks appropriate permissions to read files, discover paths, etc.
MessageBox.Show("Security error. Please contact your administrator for details.\n\n" +
"Error message: " + ex.Message + "\n\n" +
"Details (send to Support):\n\n" + ex.StackTrace
);
}
catch (Exception ex)
{
// Could not load the image - probably related to Windows file system permissions.
MessageBox.Show("Cannot display the image: " + file.Substring(file.LastIndexOf('\\'))
+ ". You may not have permission to read the file, or " +
"it may be corrupt.\n\nReported error: " + ex.Message);
}
}
}

Combining both answers, here's the code I came up with to:
Enabling the user to Select Multiple XLSX Files (using MultiSelect, OpenFileDialog, this.OpenFileDialog Properties & FileBrowserDialog)
After selection is made, Display Selected XLSX Filenames in Textbox (by setting textBoxSourceFiles.Text value to sourceFileOpenFileDialog.FileNames)
Copy the Selected Files to a separate Consolidated directory (using foreach loop, System.IO.File.Copy, System.IO.Path.GetFileName, sourceFileOpenFileDialog.FileName)
private void sourceFiles_Click(object sender, EventArgs e)
{
Stream myStream;
OpenFileDialog sourceFileOpenFileDialog = new OpenFileDialog();
this.sourceFileOpenFileDialog.InitialDirectory = "i:\\CommissisionReconciliation\\Review\\";
this.sourceFileOpenFileDialog.Filter = "Excel Files (*.xls;*.xlsx;)|*.xls;*.xlsx;|All Files (*.*)|*.*";
this.sourceFileOpenFileDialog.FilterIndex = 2;
this.sourceFileOpenFileDialog.RestoreDirectory = true;
this.sourceFileOpenFileDialog.Multiselect = true;
this.sourceFileOpenFileDialog.Title = "Please Select Excel Source File(s) for Consolidation";
if (sourceFileOpenFileDialog.ShowDialog() == DialogResult.OK)
{
try
{
if ((myStream = sourceFileOpenFileDialog.OpenFile()) != null)
{
using (myStream)
{
// populates text box with selected filenames
textBoxSourceFiles.Text = sourceFileOpenFileDialog.FileNames;
}
} // ends if
} // ends try
catch (Exception ex)
{
MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
}
} // ends if (sourceFileOpenFileDialog.ShowDialog() == DialogResult.OK)
} // ends public void sourceFiles_Click
private void consolidateButton_Execute_Click(object sender, EventArgs e)
{
string consolidatedFolder = targetFolderBrowserDialog.SelectedPath;
foreach (String file in sourceFileOpenFileDialog.FileNames)
{
try
{
// Copy each selected xlsx files into the specified TargetFolder
System.IO.File.Copy(sourceFileOpenFileDialog.FileName, consolidatedFolder + #"\" + System.IO.Path.GetFileName(sourceFileOpenFileDialog.FileName));
Log("File" + sourceFileOpenFileDialog.FileName + " has been copied to " + consolidatedFolder + #"\" + System.IO.Path.GetFileName(sourceFileOpenFileDialog.FileName));
}
} // ends foreach loop
} // ends void consolidateButton_Execute_Click
