Dear All.,
I want to read a column which has 2 blob format in the below code
I have 2 blob format in the same column as the following:
1- Colour picture start with 0000 WIDTH=480 HEIGHT=640
2- B&W (Black and white) picture start with FF B&W WIDTH=153 HEIGHT=208
I am using DB2 VER10.5 AND VS 2010, I get the below error when I try to read them
System.ArgumentException: Parameter is not valid.
at System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData)
at System.Drawing.Image.FromStream(Stream stream)
at PHOTOSMATCH.Form4.Button1_Click(Object sender, EventArgs e) in E:\PHOTOSMATCH\PHOTOSMATCH\Form4.vb:line 72
at System.Windows.Forms.Control.OnClick(EventArgs e)
at System.Windows.Forms.Button.OnClick(EventArgs e)
at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent)
at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks)
at System.Windows.Forms.Control.WndProc(Message& m)
at System.Windows.Forms.ButtonBase.WndProc(Message& m)
at System.Windows.Forms.Button.WndProc(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)
at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)
So, How can I solve the parameter error to be able to read both format?
Thanks for your co-operations.
