URL of image

[Raul2]

Hi from Spain,

I have this url, http://localhost/?id=266&doc=90630&tipo=i, for URL property in a image, but dont show anything at designer or rendered, but if I copy and paste this url in Internet Explorer, it show me the image, open it, no download.
Does designer needs the clean url to image file?

The version is 2009.3

Thanks, regards.

Hello Raul,

We use following code to load image from url:

Code: Select all

using System;
using System.Net;
using System.Drawing;
using System.Drawing.Imaging;
using System.ComponentModel;
using System.IO;

public static Image LoadBitmap(string url)
{
	WebClient cl = new WebClient();
	cl.Credentials = CredentialCache.DefaultCredentials;
	byte [] bytes = cl.DownloadData(url);
        cl.Dispose();

	MemoryStream stream = new MemoryStream(bytes);
        return new Bitmap(stream);
}

Try to load your image with help of this method.

Thank you.

Hi Jan, thanks for your response.

With the url http://localhost/?id=266&doc=90630&tipo=i as parameter for this method I get a error of "The parameter is not valid." when render. I use this:

Code: Select all

Image2.Image = LoadBitmap("http://localhost/?id=266&doc=90630&tipo=i")

Hi Raúl,

In that case please use absolute or relative URLs for images. Nice example of that:

Thank you.

Thanks for the info.

and could be possible something like this?:

Code: Select all

Me.Image1.File = "C:\Images\" + {FILES.FILE_NAME}
or 
Me.Image1.File = "C:\Images\" + {FILES.FILE_NAME} + ".jpg"

Hi,

Yes, that is possible:

string p = "C:\\Images\\" + FILES.FILE_NAME.ToString()+".jpg";

im.Image = Image.FromFile(p);

Thank you.

Now I am trying to show some images in a data element with 2 columns. The name of the image files is stored in a field of a table, looking this thread (http://forum.stimulsoft.com/default.aspx?g=posts&t=2857) I try to put in the "Image Data" of the Image1 located in first column in the data element this code:

Code: Select all

{Image.FromFile("C:\Images\" + FILES.FILE_NAME.ToString() + ".jpg"}

but i get error because in the code I have this:

Code: Select all

Public Sub Image1__GetImageData(ByVal sender As Object, ByVal e As Stimulsoft.Report.Events.StiGetImageDataEventArgs)
            e.Value = "{Image.FromFile(""C:\Images\"" + FILES.FILE_NAME.ToString() + "".jpg""}"
End Sub

How I must write it in "Image Data"?

Thanks and sorry for my bad English.

Hello,

Please check following:

Code: Select all

Image.FromFile("C:\Images\" + FILES.FILE_NAME.ToString() + ".jpg"

Thank you.

I get this now:

Code: Select all

Public Sub Image1__GetImageData(ByVal sender As Object, ByVal e As Stimulsoft.Report.Events.StiGetImageDataEventArgs)
            e.Value = "Image.FromFile(""C:\Images\"" + FILES.FILE_NAME.ToString() + "".jpg"""
End Sub

but I have solved it saving the entire path in the field:

Code: Select all

{Image.FromFile(FILES.ENTIRE_PATH)}

Thanks for help me.
