I am trying to display an image from database, and I keep ending up with an error Parameter is not valid. Bitmap bm2 = new Bitmap(targetW, targetH);
I have tried different ways but I can't get it to work (as you can see in my commented code). I am having trouble on the saving it to the database process, displaying it isn't a problem (when I had valid images)
[Code]....
I am getting a parameter is not valid exception..While saving the image
Here is my code to save the image
if (!File.Exists(pictureBox1.Tag.ToString()))
{
Image image = pictureBox1.Image;
image.Save(pictureBox1.Tag.ToString(), ImageFormat.Jpeg);
}
else
{
string delStr = pictureBox1.Tag.ToString();
pictureBox1.Image.Dispose();
File.Delete(delStr);
Image image = pictureBox1.Image;
image.Save(delStr, ImageFormat.Jpeg);
pictureBox1.Image = Image.FromFile(delStr);
}
I have implemented the following functionality that connects to webservice and downloads a favicon from a given site and saves it to a byte[] which I store in our database. I now want to set it up so that it saves the icon to the disk. However I am getting a "Parameter is not valid" when I try and create the image from the byte[].My code is as follows..
stream.Write(imageByteArray, 0, imageByteArray.Length);
Image i = Image.FromStream(stream); // EXCEPTION HAPPENS HERE.
i.Save(@"C: mp" + filename + ".ico");
The exception occurs on the middle line. This code works perfectly 9 times out of ten, but for some favicons, even thought the icon is a valid image (or at least it appears to be and it shows in the browser when point at it) I get this exception. Does anyone have any ideas? I am pulling my hair out here!
I got a hard time with the Image.FromStream method in my website. The code below works perfect on my computer. But when I uploaded it to the test server, it always gives me "Parameter not valid" exception.
if (!afuImageFile.IsUploading && afuImageFile.HasFile)
{
System.Drawing.Image imgFile = System.Drawing.Image.FromStream(afuImageFile.FileContent);
}
the afuImageFile is an AsynFileUploader control in Ajax Tool Kits. afuImageFile.FileContent is a HttpInputStream.
In my asp.net+vb web with access database there is a page which displays data as per query string and the string is PNO and all data is correctly displayed in gridview and dataview. there is a Image1.ImageUrl and i used the following code but it is not working
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
Dim PNO As String
PNO = Request.QueryString("PNO")
Image1.ImageUrl = "C:/wing/Photos/" + PNO + ".jpg"
End Sub

I'm trying to get image from database into picturebox
pictureBox1.Image = Image.FromStream(new MemoryStream((byte[])ds.Tables[0].Rows[i].ItemArray[0]));
But I am getting error:
parameter is not valid
This in in an ASP.NET application.
Locally, this code runs fine, but on our production server, it throws an exception of 'Parameter is not valid' when Bitmap.Save() is called.
Should I not be using System.Drawing.Bitmap because its not recommened based on this:
[URL]
Classes within the System.Drawing namespace are not supported for use within a Windows or ASP.NET service. Attempting to use these classes from within one of these application types may produce unexpected problems, such as diminished service performance and run-time exceptions.
What else could I use?
Bitmap myBitmap = new Bitmap(img);
myBitmap.SetResolution(img.HorizontalResolution, img.VerticalResolution);
// get the tiff codec info
ImageCodecInfo myImageCodecInfo = GetEncoderInfo("image/tiff");
// Create an Encoder object based on the GUID for the Compression parameter category
System.Drawing.Imaging.Encoder myEncoder = System.Drawing.Imaging.Encoder.Compression;
// create encode parameters
EncoderParameters myEncoderParameters = new EncoderParameters(1);
EncoderParameter myEncoderParameter = new EncoderParameter(myEncoder, (long)EncoderValue.CompressionCCITT4);
myEncoderParameters.Param[0] = myEncoderParameter;
// save as a tiff
myBitmap.Save(input, myImageCodecInfo, myEncoderParameters);

I have a page which displays details and a pictures of employees. The details are stored in a SQL database and the images are on the server. How can I set a default Image to display (e.g. an Image saying "Awaiting Image") if an employee picture is missing?
I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.
