VB Add/Edit/Save Pictures in Access DB

Mar 16th, 2009

Hi everyone, is it possible to add/edit/save picture in MS Access DB using ADO, I have this code

If (MsgBox("Are you sure you entered correct data?" & vbNewLine & "Save now?", vbYesNo + vbQuestion, "Confirm Save") = vbYes) Then
squery = "": squery = "SELECT * FROM tblEmp"
Call ExecuteCommand
Set rs = New ADODB.Recordset
With rs
.Open squery, conn, adOpenStatic, adLockPessimistic
.AddNew
.Fields("EmpID") = txtEmpID.Text
.Fields("LName") = txtLast.Text
.Fields("FName") = txtFirst.Text
.Fields("MName") = txtMiddle.Text
.Fields("Pos") = txtPos.Text
.Update
End With

I want also to add/save picture together with this data, using Image or PictureBox.

Then I want to retrieve it later on and display the picture within the Form based on the user's QUERY. then is it also possible to display this picture in Data Report when the user click the command PREVIEW.

Thank you very much for your help.
I will highly appreciate it.

please try to use the sample code to store picture.
this sample code uses ADO for database connection

Re: VB Add/Edit/Save Pictures in Access DB

Mar 18th, 2009

good evening:

how could this code be fitted to the above code (to what i have posted)..

for example, in my form i have imgPhoto in the form, having UPLOAD Picture button, then after locating the photo by this code:

Private Sub cmdUpload_Click()
cdPhoto.Filter = "Image Files (*.jpg;*.gif;*.bmp)|*.jpg;*.gif;*.bmp"
cdPhoto.ShowOpen
filepath = cdPhoto.FileName
imgPhoto.Picture = LoadPicture(filepath)
End Sub

by means of this code, i have successfully loaded the picture within the image on the form but for the SAVE BUTTON?

for database access:
i have field Photo defined as "OLE Object" in MS Access Datafield

what should be on the cmdSave button:

together with this,

Set rs = New ADODB.Recordset
With rs
.Open squery, conn, adOpenStatic, adLockPessimistic
.AddNew
.Fields("EmpID") = txtEmpID.Text
.Fields("LName") = txtLast.Text
.Fields("FName") = txtFirst.Text
.Fields("MName") = txtMiddle.Text
.Fields("Photo")=????
.Update

what should be added with this code or anything much simpler than the one you have given?

thank you very much for the reply.

You need to do the following .

1.add all the records except picture
2.update the recordset
3.edit the same record
4.update the picture field with the photo.
5.update the recordset again.

Re: VB Add/Edit/Save Pictures in Access DB

Mar 19th, 2009

good morning, i have successfully saved the picture together with the data by this code:

Private Sub cmdSave_Click()
Dim picsm As ADODB.Stream
Set picsm = New ADODB.Stream
picsm.Type = adTypeBinary
picsm.Open
picsm.LoadFromFile filepath
With rs
.AddNew
.Fields("Last") = txtLast.Text
.Fields("First") = txtFirst
.Fields("Pic").Value = picsm.Read
imgPic.Picture = LoadPicture(filepath)
.Update
MsgBox "success"
End With
picsm.Close
Set picsm = Nothing
End Sub

but my problem now is on how to retrieve the picture and load it into the image control on the form:

i have this code but it is working with data only, it retrieves the data but not the image.

Private Sub cmdSearch_Click()
On Error GoTo notfound
Dim photo As String
squery = "select * from tblpic where Last='" & txtLast.Text & "'"
Call ExecuteCommand
photo = rs.Fields("pic").Value
With Me
.txtLast = rs!Last
.txtFirst = rs!First
.imgPic.Picture = LoadPicture(photo)
End With
Exit Sub
notfound:
MsgBox "Not Found"

End Sub

any idea?

thank you...
