[RESOLVED] need help for multi display picturebox when selecting datagridview in vb.net
Dear All Master,
please provide a solution to display multi picturebox when selecting datagridview.
and is it possible to display images from subfolders?
and can I hide datatable in datagridview in column FILENAME1,FILENAME2,FILENAME,FILENAME 4 on my select and show image in multi picturebox?
for information i use visual studio 2010.
Code:
Public Class Form1
Dim Path As String = "C:\Users\Administrator\Desktop\DBF"
Dim Pathimage As String = "C:\Users\Administrator\Desktop\CATALOG"
Dim cn = "provider=Microsoft.Jet.OLEDB.4.0; data source=" & Path & "; Extended Properties=dBase IV"
Private Sub PopulateDataGridView()
Try
Dim dt = New DataTable()
Dim query = "select ITM,ITC,QOH,PRS,FILENAME1,FILENAME2,FILENAME3,FILENAME4 FROM ITEM"
Using adapter As New OleDbDataAdapter(query, cn.ToString)
adapter.Fill(dt)
End Using
Me.DataGridView1.DataSource = dt
Catch myerror As OleDbException
MessageBox.Show("Error: " & myerror.Message)
Finally
End Try
End Sub
Private Sub DataGridView1_CellContentClick(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim dgv As DataGridView = CType(sender, DataGridView)
Dim thisCell As DataGridViewCell = dgv.SelectedCells(0)
Dim selCell As Integer = thisCell.ColumnIndex
TextBox2.Text = Pathimage & "\" & DataGridView1.CurrentRow.Cells(selCell).Value.ToString()
If Not (pbAdder.Image Is Nothing) Then
pbAdder.Image.Dispose()
pbAdder.Image = Nothing
End If
pbAdder.Image = Image.FromFile(TextBox2.Text)
End Sub

Re: need help for multi display picturebox when selecting datagridview in vb.net
To display images from a different folder, based on the filenames you have in your database, i'd use extended PictureBoxes...
Add the class to your project, then rebuild. You'll find exPictureBox at the top of your toolbox.
Code:
Public Class exPictureBox
Inherits PictureBox
Private _prePath As String
Public Property PrePath() As String
Get
Return _prePath
End Get
Set(ByVal value As String)
_prePath = value
End Set
End Property
Private _fileName As String
Public Property FileName() As String
Get
Return _fileName
End Get
Set(ByVal value As String)
_fileName = value
MyBase.ImageLocation = If(value <> "", PrePath & value, "")
End Set
End Property
End Class
Then you can use databinding as i showed you...
Code:
Public Class Form1
Dim Path As String = "C:\Users\Administrator\Desktop\DBF"
Dim Pathimage As String = "C:\Users\Administrator\Desktop\CATALOG"
Dim cn = "provider=Microsoft.Jet.OLEDB.4.0; data source=" & Path & "; Extended Properties=dBase IV"
Private Sub PopulateDataGridView()
Try
Dim dt = New DataTable()
Dim query = "select ITM,ITC,QOH,PRS,FILENAME1,FILENAME2,FILENAME3,FILENAME4 FROM ITEM"
Using adapter As New OleDbDataAdapter(query, cn.ToString)
adapter.Fill(dt)
End Using
Me.DataGridView1.DataSource = dt
For x as integer = 4 to 7
Me.DataGridView1.Columns(x).Visible = False
Next
exPictureBox1.PrePath = Pathimage & "\"
exPictureBox2.PrePath = Pathimage & "\"
exPictureBox3.PrePath = Pathimage & "\"
exPictureBox4.PrePath = Pathimage & "\"
exPictureBox1.DataBindings.Add("FileName", dt, "FILENAME1")
exPictureBox2.DataBindings.Add("FileName", dt, "FILENAME2")
exPictureBox3.DataBindings.Add("FileName", dt, "FILENAME3")
exPictureBox4.DataBindings.Add("FileName", dt, "FILENAME4")
Catch myerror As OleDbException
MessageBox.Show("Error: " & myerror.Message)
Finally
End Try
End Sub
End Class

Dear Mr. .paul.
Thank you for your reply. I've tried if it's only in 1 parent folder then it appears at once in the expicturebox. I tried to create a subfolder and it contained an image file but it didn't appear in the expicturebox. example path "C:\Users\Administrator\Desktop\CATALOG\test" & "C:\Users\Administrator\Desktop\CATALOG\test\test1".
Thanks

Re: need help for multi display picturebox when selecting datagridview in vb.net
exPictureBox PrePath has to contain the correct path, and end with “\”

Dear Mr. .paul.
if so it means I have to have 1 column in the datagriview which is "helper path" so that it can be used for images in subfolders.
Thanks

Ok. So assuming you have...
Code:
Dim Pathimage As String = "C:\Users\Administrator\Desktop\CATALOG"
as your base folder, you can enumerate sub folders, to find the path for the 'FileName'
Code:
Public Class exPictureBox
Inherits PictureBox
Private _prePath As String
Public Property PrePath() As String
Get
Return _prePath
End Get
Set(ByVal value As String)
_prePath = value
End Set
End Property
Private _fileName As String
Public Property FileName() As String
Get
Return _fileName
End Get
Set(ByVal value As String)
_fileName = value
' You can search subfolders here to get the correct folder path for 'value' which is the filename in your datatable.
MyBase.ImageLocation = If(value <> "", PrePath & value, "")
End Set
End Property
End Class
Re: need help for multi display picturebox when selecting datagridview in vb.net
This will work, as long as you don't use duplicate filenames in your directory structure...
Code:
Imports System.IO.Directory
Public Class exPictureBox
Inherits PictureBox
Private _prePath As String
Public Property PrePath() As String
Get
Return _prePath
End Get
Set(ByVal value As String)
_prePath = value
End Set
End Property
Private _fileName As String
Public Property FileName() As String
Get
Return _fileName
End Get
Set(ByVal value As String)
_fileName = value
Dim files As List(Of String) = SearchForFile(PrePath, value)
If value <> "" AndAlso files.count > 0 Then
MyBase.ImageLocation = files.First
Else
MyBase.ImageLocation = ""
End If
End Set
End Property
Function SearchForFile(ByVal RootFolder As String, ByVal searchFileName As String) As List(Of String)
Dim ReturnedData As New List(Of String) 'List to hold the search results
Dim FolderStack As New Stack(Of String) 'Stack for searching the folders
FolderStack.Push(RootFolder) 'Start at the specified root folder
Do While FolderStack.Count > 0 'While there are things in the stack
Dim ThisFolder As String = FolderStack.Pop 'Grab the next folder to process
Try 'Use a try to catch any errors
For Each SubFolder In GetDirectories(ThisFolder) 'Loop through each sub folder in this folder
FolderStack.Push(SubFolder) 'Add to the stack for further processing
Next 'Process next sub folder
ReturnedData.AddRange(GetFiles(ThisFolder, searchFileName)) 'Process searchFileName
Catch ex As Exception 'For simplicity sake
'We'll ignore the errors
End Try
Loop 'Process next folder in the stack
Return ReturnedData 'Return the list of files that match
End Function
End Class

Dear .paul. ,
I attach a screenshot of what I mean.
if the subfolder is like in the screenshot, please provide an example of the class code
thanks

Dear Mr. .paul.
thank you very much for the code you provided
it's going so perfectly
I want to ask how to make a fit image in expicturebox 1-4?
thanks
