Parameter is not valid error in MemoryStream

Question

User-1360958501 posted

G'day,

I'm out of my depth but I know this routine works but when I apply it to my own ends I get this error.  Can someone please shed some light as to the likely cause.  The imageFile object exists and is a byte array.  

<!--StartFragment --><code> 
Exception Details: System.ArgumentException: Parameter is not valid.

Source Error:

Line 46: Private Function ResizeImageFile(ByVal imageFile() As Byte, ByVal targetSize As Integer) As Byte() Line 47: Dim original As System.Drawing.Image Line 48: original = System.Drawing.Image.FromStream(New MemoryStream(imageFile)) Line 49: Dim targetH As Integer Line 50: Dim targetW As Integer

Stack Trace:

[ArgumentException: Parameter is not valid.] System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement, Boolean validateImageData) +339 System.Drawing.Image.FromStream(Stream stream, Boolean useEmbeddedColorManagement) +33 System.Drawing.Image.FromStream(Stream stream) +27

Ever get a resolution to this issue? I'm having the same problem. I get it when I try to pull an image out of sql server if that image was pushed into sql server via access (linked table).

if imageFile is your byte array then following will work.

Dim ms As New MemoryStream()
ms.Write(imageFile, 0, imageFile.Length)

Dim original As New System.Drawing.Bitmap(ms)

its not working, i am tires and still have error.

insert code is:

SqlConnection con = dbcls.openConncection();

SqlCommand myCommand = new SqlCommand(query, con);

myCommand.Parameters.Add("@ImageData", SqlDbType.Image, 16, "picture");

myCommand.Parameters["@ImageData"].Value = byt;

int i = myCommand.ExecuteNonQuery();

insert code is working. but retrieve code not working:

byte[] imageData = (byte[])row["picture"];

System.Drawing.Image newImage;

//Read image data into a memory stream

using (MemoryStream ms = new MemoryStream(imageData, 0, imageData.Length))

{

ms.Write(imageData, 0, imageData.Length);

//Set image variable value using memory stream.

newImage = System.Drawing.Bitmap.FromStream(ms);

}

newImage = System.Drawing.Image.FromStream(ms,true);

 jst check it out with the following solution

it works for me

  Bitmap btm = new Bitmap(rr.ToString());//give the path from where u want the exact image
        Bitmap btm_new = new Bitmap(btm, btm.Width, btm.Height);
        btm_new.SetResolution(btm.HorizontalResolution, btm.VerticalResolution);
        Graphics g = Graphics.FromImage(btm_new);
        btm.Dispose();
        btm = btm_new;

btm.Save("");//jst give the path where u want to save that image
     
       
        g.Dispose();
        btm.Dispose();
