I'm using this code to save files in my app
Dim filePath = String.Format("image{0:yyyyMMddHHmmss}.png", DateTime.Now)
PictureBox1.Image.Save(IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), (filePath)))
So now I have a textbox1 and I want to show the path of last saved image in it
how?
Regards,,,,
What I've done in the past is generate the path in one step and then use the generated variable to do the saving and to display.
So instead of:
Dim filePath = String.Format("image{0:yyyyMMddHHmmss}.png", DateTime.Now)
PictureBox1.Image.Save(IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), (filePath)))
Try:
'Generate the Path
Dim path As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), String.Format("image{0:yyyyMMddHHmmss}.png", DateTime.Now))
'Save using the generated path
PictureBox1.Image.Save(path)
'Display the path
textbox1.Text = path
Thanks all I've done it successfully `
Dim filename As String = String.Format("image{0:yyyyMMddHHmmss}.png", DateTime.Now)
Dim filePath1 = (IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), (filename)))
Dim filePath2 = (IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), ("RMSS")))
If IO.Directory.Exists(IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), (" RMSS"))) = True Then
TextBox1.Text = filePath1
TextBox2.Text = filePath2 & "\" & filename
PictureBox1.Image.Save(filePath1)
My.Computer.FileSystem.MoveFile(TextBox1.Text, TextBox2.Text, True)
Else
TextBox1.Text = filePath1
TextBox2.Text = filePath2 & "\" & filename
PictureBox1.Image.Save(filePath1)
My.Computer.FileSystem.MoveFile(TextBox1.Text, TextBox2.Text, True)
End If

I am trying to make a program that will zip all the files in the same folder.
But I'm having issues with it. It's giving me an error saying the file is being used by another process.
Private Sub btnZip_Click(sender As Object, e As EventArgs) Handles btnZip.Click
Dim extension As String = txtExtension.Text
Dim paths As String = Application.StartupPath
Dim files As String() = Directory.GetFiles(paths, "*.*")
For Each file As String In files
Dim fileName As String = path.GetFileNameWithoutExtension(file)
Dim index As Integer = fileName.IndexOf("_")
If index >= 0 Then
fileName = fileName.Substring(0, index)
End If
ZipFile.CreateFromDirectory(Path.GetDirectoryName(file), paths & "\" & fileName & ".zip", CompressionLevel.Optimal, False)
Next
MessageBox.Show("Files zipped successfully!")
End Sub
I just couldn't figure out what's causing the issue.
as seen in comment, you must exclude your running application from the file list :
add
If Path.GetFileName(file) = Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName) Then Continue For
in for loop
Private Sub btnZip_Click(sender As Object, e As EventArgs) Handles btnZip.Click
Dim extension As String = txtExtension.Text
Dim paths As String = Application.StartupPath
Dim files As String() = Directory.GetFiles(paths, "*.*")
For Each file As String In files
If Path.GetFileName(file) = Path.GetFileName(System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName) Then Continue For
Dim fileName As String = Path.GetFileNameWithoutExtension(file)
Dim index As Integer = fileName.IndexOf("_")
If index >= 0 Then
fileName = fileName.Substring(0, index)
End If
ZipFile.CreateFromDirectory(Path.GetDirectoryName(file), paths & "\" & fileName & ".zip", CompressionLevel.Optimal, False)
Next
MessageBox.Show("Files zipped successfully!")
End Sub
I have a text document with a list of file names and their extensions. I need to go through this list and check a directory for the existence of each file. I then need to output the result to either foundFilesList.txt or OrphanedFiles.txt. I have two approaches to this function, and neither is working. The first example uses a loop to cycle through the text doc. The second one doesn't work it never sees a match for the file from the fileNamesList.
Thank you for taking the time to look at this.
First Code:
Dim FILE_NAME As String
FILE_NAME = txtFileName.Text
Dim fileNames = System.IO.File.ReadAllLines(FILE_NAME)
fCount = 0
For i = 0 To fileNames.Count() - 1
Dim fileName = fileNames(i)
'sFileToFind = location & "\" & fileName & "*.*"
Dim paths = IO.Directory.GetFiles(location, fileName, IO.SearchOption.AllDirectories)
If Not paths.Any() Then
System.IO.File.AppendAllText(orphanedFiles, fileName & vbNewLine)
Else
For Each pathAndFileName As String In paths
If System.IO.File.Exists(pathAndFileName) = True Then
Dim sRegLast = pathAndFileName.Substring(pathAndFileName.LastIndexOf("\") + 1)
Dim toFileLoc = System.IO.Path.Combine(createXMLFldr, sRegLast)
Dim moveToFolder = System.IO.Path.Combine(MoveLocation, "XML files", sRegLast)
'if toFileLoc = XML file exists move it into the XML files folder
If System.IO.File.Exists(toFileLoc) = False Then
System.IO.File.Copy(pathAndFileName, moveToFolder, True)
System.IO.File.AppendAllText(ListofFiles, sRegLast & vbNewLine)
fileFilename = (fileName) + vbCrLf
fCount = fCount + 1
BackgroundWorker1.ReportProgress(fCount)
'fileCount.Text = fCount
End If
End If
Next
End If
BackgroundWorker1.ReportProgress(100 * i / fileNames.Count())
'statusText = i & " of " & fileName.Count() & " copied"
fCount = i
Next
Second Code:
FILE_NAME = txtFileName.Text 'textfield with lines of filenames are located ]
Dim fileNamesList = System.IO.File.ReadAllLines(FILE_NAME)
location = txtFolderPath.Text
fCount = 0
' Two list to collect missing and found files
Dim foundFiles As List(Of String) = New List(Of String)()
Dim notfoundFiles As List(Of String) = New List(Of String)()
Dim fileNames As String() = System.IO.Directory.GetFiles(createXMLFldr)
For Each file As String In fileNamesList
Debug.Write("single file : " & file & vbCr)
' Check if the files is contained or not in the request list
Dim paths = IO.Directory.GetFiles(location, file, IO.SearchOption.AllDirectories)
If fileNamesList.Contains(Path.GetFileNameWithoutExtension(file)) Then
Dim FileNameOnly = Path.GetFileName(file)
Debug.Write("FileNameOnly " & FileNameOnly & vbCr)
If System.IO.File.Exists(FileNameOnly) = True Then
'if toFileLoc = XML file exists move it into the XML files folder
Dim moveToFolder = System.IO.Path.Combine(MoveLocation, "XML files", file)
foundFiles.Add(file) 'add to foundFiles list
fileFilename = (file) + vbCrLf 'add file name to listbox
fCount = fCount + 1
Else
notfoundFiles.Add(file)
End If
End If
Next
File.WriteAllLines(ListofFiles, foundFiles)
File.WriteAllLines(orphanedFiles, notfoundFiles)
This is just a starting point for you, but give it a try:
Friend Module Main
Public Sub Main()
Dim oFiles As List(Of String)
Dim _
sOrphanedFiles,
sSearchFolder,
sFoundFiles,
sTargetFile As String
sOrphanedFiles = "D:\Results\OrphanedFiles.txt"
sSearchFolder = "D:\Files"
sFoundFiles = "D:\Results\FoundFiles.txt"
oFiles = IO.File.ReadAllLines("D:\List.txt").ToList
oFiles.ForEach(Sub(File)
If IO.Directory.GetFiles(sSearchFolder, File, IO.SearchOption.AllDirectories).Any Then
sTargetFile = sFoundFiles
Else
sTargetFile = sOrphanedFiles
End If
IO.File.AppendAllText(sTargetFile, $"{File}{Environment.NewLine}")
End Sub)

i need to create a condition that will move/copy selected multiple files from one folder to another i used openfile dialogue to browse files and set it to multiselect, i then created a label for the directory and filename the condition that i'm using right now only copies one selected file, i need to save all selected files at once.
this code is for insert attachments
Dim a As OpenFileDialog = New OpenFileDialog
a.Multiselect = True
If a.ShowDialog() = Windows.Forms.DialogResult.OK Then
removeatt.Show()
removeatt.Text = "Remove Attachment"
fpath.Text = a.FileName
fname.Text = System.IO.Path.GetFileName(a.FileName)
Dim file As String
file = fpath.Text.ToString
Label7.Text = file
If fpath.Text = "-" Then
removeatt.Hide()
Else
removeatt.Show()
End If
End If
and this is for the saving/copying part
Dim dir As String
Dim dir2 As String
dir = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
dir2 = Path.Combine(dir, "Site images and attachments/" & Label33.Text & "/")
If Not Directory.Exists(dir2) Then
Directory.CreateDirectory(dir2)
End If
If fpath.Text = "-" Then
Else
My.Computer.FileSystem.CopyFile(fpath.text, dir2 + fname.Text, Microsoft.VisualBasic.FileIO.UIOption.AllDialogs, Microsoft.VisualBasic.FileIO.UICancelOption.DoNothing)
End If
again, i need it to save the all the selected files
thanks
in this code i will show you how to get all files path.
for saving part you have to split generated text and do the same.
Dim a As OpenFileDialog = New OpenFileDialog
Dim fname As String
a.Multiselect = True
If a.ShowDialog() = Windows.Forms.DialogResult.OK Then
removeatt.Show()
removeatt.Text = "Remove Attachment"
For Each fname In a.FileNames
fpath.Text = fpath.Text + IIf(fpath.Text.Trim <> "", "-", "") + fname
Next
Label7.Text = fpath.Text
End If
for saving part you may split fpath.text with "-" character and put result into a string array like this:
dim filenames as string() <--- this is how to define string array
filenames = f.path.text.split("-")
for each file as string in filenames
<----- save file commands

This is going to be a long one, but easy fix.
So i've manage to convert a pdf to string, then able to print an external pdf simply by putting the name of the file in a textbox.
I've also figured how to extract certain text from the pdf string, now the certain text are also files located in an external location (I use c:\temp\ for testing).
Which leaves me with one problem, the text I extract, I use shellexecute to print, works fine if its one string. however, If the file name I extract is more than one it will count it as a single string, thus adding the location and .pdf to that one string. instead of the two or more strings. which will do something like this:
As you can see, it will send that to the printer. I want to send one at a time to the printer. like this:
I've tried using an Arraylist and various methods. but my own lack of knowledge, I cannot figure it out.
I'm thinking a "for loop" will help me out. any ideas?
Below is my code.
Dim pdffilename As String = Nothing
pdffilename = RawTextbox.Text
Dim filepath = "c:\temp\" & RawTextbox.Text & ".pdf"
Dim thetext As String
thetext = GetTextFromPDF(filepath) ' converts pdf to text from a function I didnt show.
Dim re As New Regex("[\t ](?<w>((asm)|(asy)|(717)|(ssm)|(715)|(818))[a-z0-9]*)[\t ]", RegexOptions.ExplicitCapture Or RegexOptions.IgnoreCase Or RegexOptions.Compiled) ' This filters out and extract certain keywords from the PDF
Dim Lines() As String = {thetext}
Dim words As New List(Of String)
For Each s As String In Lines
Dim mc As MatchCollection = re.Matches(s)
For Each m As Match In mc
words.Add(m.Groups("w").Value)
Next
RawRich4.Text = String.Join(Environment.NewLine, words.ToArray)
Next
'This is where I need help with the code. how to have "words" putout "c:\temp\" & RawRich4.Text & ".pdf" with each keyword name
Dim rawtoprint As String = String.Join(Environment.NewLine, words.ToArray)
Dim defname As String = Nothing
defname = RawRich4.Text
rawtoprint = "c:\temp\" & RawRich4.Text & ".pdf"
Dim psi As New System.Diagnostics.ProcessStartInfo()
psi.UseShellExecute = True
psi.Verb = "print"
psi.WindowStyle = ProcessWindowStyle.Hidden
psi.Arguments = PrintDialog1.PrinterSettings.PrinterName.ToString()
psi.FileName = (rawtoprint) ' this is where the error occurs it doesn't send both files separately to the printer, it tries to send it as one name
MessageBox.Show(rawtoprint) ' This is just to test the output, this will be removed.
'Process.Start(psi)
End Sub
Updated.
Imports System.Text.RegularExpressions
Module Program
Sub Main()
Dim pdffilename As String = RawTextbox.Text
Dim filepath = "c:\temp\" & RawTextbox.Text & ".pdf"
Dim thetext As String
thetext = GetTextFromPDF(filepath) ' converts pdf to text from a function I didnt show.
'thetext = "Random text here and everywhere ASM00200207 1 1 same here bah boom 12303 doh hel232 ASM00200208 1 2 "
Dim pattern As String = "(?i)[\t ](?<w>((asm)|(asy)|(717)|(ssm)|(715)|(818))[a-z0-9]*)[\t ]"
For Each m As Match In rgx.Matches(thetext, pattern)
'Console.WriteLine("C:\temp\" & Trim(m.ToString) & ".pdf")
RawPrintFunction("C:\temp\" & Trim(m.ToString) & ".pdf")
Next
End Sub
Function RawPrintFunction(ByVal rawtoprint As String) As Integer
Dim psi As New System.Diagnostics.ProcessStartInfo()
psi.UseShellExecute = True
psi.Verb = "print"
psi.WindowStyle = ProcessWindowStyle.Hidden
psi.Arguments = PrintDialog1.PrinterSettings.PrinterName.ToString()
MessageBox.Show(rawtoprint) This will be removed, this is just for testing to see what files will be printed
'Process.Start(psi) This will be uncomment.
return 0
End Function
End Module
If I don't misunderstand the code -since I can't test and run it here- you can iterate through file names stored in words variable and send it to printer. Following is an example on how to do that :
....
....
Dim Lines() As String = {thetext}
Dim words As New List(Of String)
For Each s As String In Lines
Dim mc As MatchCollection = re.Matches(s)
For Each m As Match In mc
words.Add(m.Groups("w").Value)
Next
RawRich4.Text = String.Join(Environment.NewLine, words.ToArray)
Next
For Each fileName As String In words
Dim rawtoprint As String
rawtoprint = "c:\temp\" & fileName & ".pdf"
Dim psi As New System.Diagnostics.ProcessStartInfo()
psi.UseShellExecute = True
psi.Verb = "print"
psi.WindowStyle = ProcessWindowStyle.Hidden
psi.Arguments = PrintDialog1.PrinterSettings.PrinterName.ToString()
psi.FileName = (rawtoprint) ' this is where the error occurs it doesn't send both files separately to the printer, it tries to send it as one name
MessageBox.Show(rawtoprint) ' This is just to test the output, this will be removed.
'Process.Start(psi)

I have a checked list box and a thumbnail area to display them where I am trying to load only images from a specific folder and need to display in thumbnails area but the problem is there is a thumbs.db file which is also being added to the checked list box which I don't need it.
So how do I actually load only the image files without the thumbs.db file.
Here is my code:
Private Sub LoadProjectToolStripMenuItem_Click(sender As Object, e As EventArgs) Handles LoadProjectToolStripMenuItem.Click
Using ofdlg As New Windows.Forms.OpenFileDialog
ofdlg.DefaultExt = "trk"
ofdlg.Filter = "Project|*.trk"
ofdlg.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
If ofdlg.ShowDialog = Windows.Forms.DialogResult.OK Then
Dim SaveData As New gCanvasData
Using objStreamReader As New StreamReader(ofdlg.FileName)
Dim x As New XmlSerializer(GetType(gCanvasData))
SaveData = CType(x.Deserialize(objStreamReader), gCanvasData)
objStreamReader.Close()
End Using
With SaveData
'gTSSizer_gAZoom.Value = 100
GCanvas1.ImageXYReset()
GCanvas1.Image = .Image
GCanvas1.gAnnotates = .gAnnotates
GCanvas1.RebuildAll()
GCanvas1.AssembleBitmap()
End With
Dim fullpath As String
fullpath = Application.StartupPath + "\" & System.IO.Path.GetFileNameWithoutExtension(ofdlg.FileName) + "\"
For Each fi As FileInfo In New DirectoryInfo(fullpath).GetFiles
CheckedListBox1.Items.Add(Application.StartupPath + "\" & System.IO.Path.GetFullPath(ofdlg.FileName))
For i As Integer = 0 To CheckedListBox1.Items.Count - 1
CheckedListBox1.SetItemChecked(i, True)
ThumbControl1.AddFolder(fullpath, True)
Next i
Next
End If
End Using
End Sub
Either filter it inside of the For Each Loop:
For Each fi As FileInfo In New DirectoryInfo(fullpath).GetFiles
If Not {".jpg", ".png", ".bmp"}.Contains(fi.Extension) Then Continue For
' ...
Next
or do it in the GetFiles:
DirectoryInfo(fullpath).GetFiles(".jpg")
Found the solution at last:
Dim fullpath As String
fullpath = Application.StartupPath & "\" & System.IO.Path.GetFileNameWithoutExtension(ofdlg.FileName) + "\"
Dim FileDirectory As New IO.DirectoryInfo(fullpath)
Dim FileJpg As IO.FileInfo() = FileDirectory.GetFiles("*.jpg")
Dim FileGif As IO.FileInfo() = FileDirectory.GetFiles("*.gif")
Dim FileBmp As IO.FileInfo() = FileDirectory.GetFiles("*.bmp")
For Each File As IO.FileInfo In FileJpg
CheckedListBox1.Items.Add(File.FullName)
Dim str As String
str = Directory.GetCurrentDirectory() & "\" & "Backup\"
Next
For Each File As IO.FileInfo In FileGif
CheckedListBox1.Items.Add(File.FullName)
Dim str As String
str = Directory.GetCurrentDirectory() & "\" & "Backup\"
Next
For Each File As IO.FileInfo In FileBmp
CheckedListBox1.Items.Add(File.FullName)
Dim str As String
str = Directory.GetCurrentDirectory() & "\" & "Backup\"
Next
For i As Integer = 0 To CheckedListBox1.Items.Count - 1
CheckedListBox1.SetItemChecked(i, True)
Next i
Change DirectoryInfo(fullpath).GetFiles to DirectoryInfo(fullpath).EnumerateFiles() And add a search pattern for the image file extensions you want. http://msdn.microsoft.com/en-us/library/dd383574.aspx
