Dave Kreskowiak Microsoft MVP - Visual Basic how to save a file into MS Access Table... Nouvand3-Aug-06 0:56 Nouvand 3-Aug-06 0:56  hi.. everybody.. hope you can help me with this thing. Do you have any idea, how to save a file into MS Access database using VB 2005? Here's the simple scheme of the table FieldName {Data Type} -------------------------- Date {Date} EmployeeID {Number/Integer} Attachment {OLE Object} -------------------------- I red the MSDN help, but still haven't any idea how to apply it into my case. Or should i make an array of bytes stream of the file and then store it into 'Attachment' field. But then how the to read and restore/create the file back? Thanks before.. Re: how to save a file into MS Access Table... Kschuler3-Aug-06 2:59 Kschuler 3-Aug-06 2:59  I haven't done anything like this with access, but with another database I declared a column of type blob....which essentially IS an array of bytes. That way I could store any type of file (.pdf, .jpg, .gif,...) Perhaps searching for information using the keyword "blob" will help you. Sorry i couldn't be more helpful. Re: how to save a file into MS Access Table... Nouvand3-Aug-06 16:29 Nouvand 3-Aug-06 16:29  Thanks anyway.. Re: how to save a file into MS Access Table... Stephen McGuire3-Aug-06 12:12 Stephen McGuire 3-Aug-06 12:12  This is an image file? Do you want to embed them in the database or create a link to them? OLE Object fields can be set to embed or link to an image or other OLE file such as a Word document or Excel workbook. Embedding an image (especially GIF and JPEG) will cause the size of the database to grow far beyond the size of the image files you embed and may cause the database to run much slower. Part of the reason is that Access creates a bitmap (bmp) of the image for display information purposes. Also, If users are using Access forms, they will need additional software to view images other than bitmap (.bmp) or device independent bitmap (.dib) files on a standard Windows installation. If the OLE Object field in the database is set to 'Link' instead of 'Embed' then all you need to do is store the path to the file. Steve Re: how to save a file into MS Access Table... Nouvand3-Aug-06 16:52 Nouvand 3-Aug-06 16:52  It will be pdf or ms office files. I want to embed it to the database. Here i tell you the concept we want to meet to: We have several teams on the field. And those team will use and report the data using that database. So for this purpose, i create the replica set. Frequently, they have to submit the pre-formated report in office(doc,xls,ppt) and pdf. The teams report once every month. So all they have to do is just to send the database file and at HQ team will syncronize the database and send it back to the field. I never use OLE object, so it possible to store array of byte into it? Is it take more space? ty Re: how to save a file into MS Access Table... Nouvand3-Aug-06 21:48 Nouvand 3-Aug-06 21:48  Wow... i just found it... Just take a line of code to read a file into an array of bytes, and a line for write the bytes array into a file... ty Microsoft Re: how to save a file into MS Access Table... Stephen McGuire4-Aug-06 1:01 Stephen McGuire 4-Aug-06 1:01  If the column contains an array of bytes, I'm not sure Access will display the file. I think you would need code to extract the bytes to a file again. Also, you may want to try a few examples because, as I said, embedding files in Access (especially images) increases the file size by a huge amount. THis may not be the case with an array of bites...

Stephen McGuire3-Aug-06 12:38 Stephen McGuire 3-Aug-06 12:38  You have single quotes inside your double quotes. You should only include these for 'string' values. Numbers should not have single quotes. Additionally, 'Date' fields may need octothorpes (#) instead of single quotes. Your commands are setup a little inefficiently. You should only keep a connection open for the shortest time possible. Do everything else first, then open the connection just before you execute your command, then close immediately. Try this: Private Sub AddSubmitB_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddSubmitB.Click Dim strcon As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Documents and Settings\Jasmine\db.mdb" Dim con As OleDb.OleDbConnection con = New OleDb.OleDbConnection(strcon) Dim cmd As New OleDb.OleDbCommand cmd.Connection = con Dim strsql As String strsql = "Insert into member (BorrowerId, password, MemberType, Fname, Lname, Gender, Address1, Address2, Address3, ContactNo, HandPhNo, Email, CourseOfStudy, EnrolledDate, ExpiryDate) values ('" & StudIdTB.Text & "','" & StudPwTB.Text & "','" & UgTB.Text & "','" & StudFnTB.Text & "','" & StudLnTB.Text & "','" & StudGenderCLB.Text & "','" & StudAdd1TB.Text & "','" & StudAdd2TB.Text & "','" & StudAdd3TB.Text & "','" & StudHmTB.Text & "','" & StudHpTB.Text & "','" & StudMailTB.Text & "','" & CosCB.Text & "','" & EnrolledCB.Text & "','" & ExpiryCB.Text & "')" cmd.CommandText = strsql con.Open() cmd.ExecuteNonQuery() con.Close() MsgBox("New Member Added!") Me.Close() End Sub I haven't changed any of strsql because you seem to think the query is ok. Only you would know that. Check the single quotes etc are legal.. For queries containing this many fields, you should be using parameter queries. Once you get used to them, you will use them all the time. They are much easier to read and you can check/set data types as you go. Steve To make characters in the text of TextBox ReadOnly. Prodigy2012-Aug-06 23:02 Prodigy201 2-Aug-06 23:02  Hi All !! I am new to VB.NET... I want to make the characters in the text of TextBox control read only... That is, those characters should not be replaced by any other character, or can not be editable... So is there any property or method that can be implemented to the charactres/text(string) of textbox's text ?? Well, very clearly, I don't want to make the whole Textbox uneditable. I just want some part of input and moreover already set text in the textbox uneditable, as we can see as par as in MaskedTextBox, for e.g. in date format, we have "/" separator uneditable. So I just want to make the text uneditable. Expecting the responses. Thanks, Prodigy201 Re: To make characters in the text of TextBox ReadOnly. kyosugi2-Aug-06 23:31 kyosugi 2-Aug-06 23:31  my 1 i used the property table of the textbox scroll and go find the read-only option n set it to true Re: To make characters in the text of TextBox ReadOnly. Prodigy2013-Aug-06 0:43 Prodigy201 3-Aug-06 0:43  Hi !! Thanks for the response ! Well, I don't want to make whole textbox control as readonly, but I just want to make some part of text in the textbox readonly, i.e to make some part of the text uneditable, as we can find it in MaskedTextBox control. for e.g. "/" separator in date format (found in mask properties of MaskedTextBox) as uneditable character. So is there any property or method that can be used to make this functionality? Expecting response Thanks, Prodigy201
