saving and searching image to/from database

saving.....

Private Sub cmdSave_Click()
Dim byteData() As Byte
On Error GoTo suspect
Open CommonDialog1.FileName For Binary As #1
ReDim byteData(FileLen(CommonDialog1.FileName))
Get #1, , byteData
Close #1
Set rs = New ADODB.Recordset
rs.Open "Select * from tbl_Info", cn, 1, 2
With rs
.AddNew
!Idno = txtIdNo.Text
!Name = txtName.Text
!Picture.AppendChunk byteData
.Update
End With
MsgBox "Record save!"
txtName.Text = ""
txtIdNo.Text = ""
Image1.Picture = LoadPicture("")
Exit Sub
suspect:
MsgBox Err.Description & " Please add picture!"
End Sub

Searching........

Private Sub cmdSearch_Click()
Dim search As String
search = InputBox("enter id to search")
Set rs = New ADODB.Recordset
rs.Open "Select * from tbl_Info where idno like '" & search & "'", cn, 1, 2
Set Image1.DataSource = rs
Image1.DataField = "Picture"
txtIdNo.Text = rs!Idno
txtName.Text = rs!Name
End Sub

for ms access set picture property data type to OLE
for SQL Server set picture property data type to image

Re: Math help

jj — Fri, 20 Feb 2009 01:05:20 -0700

substition, your goal is to make one equation to have y by itself then substitute it into another equation...

Re: Math help

Weirds — Wed, 18 Feb 2009 22:22:43 -0700

1. just put y= (2x-9) into the "y" in 1st equation
ie. 3x-(2x-9) = 2 then solve

2. solve for y from 1st equation, like: y = 4-3x
then substitute this y into 2nd one

Math help

icyxmage1 — Tue, 17 Feb 2009 23:26:14 -0700

Solve by substitution:
1.
3x-y=2
y=2x-9

2.
3x+y=4
4x-3y=1
