Yes, I understand that, but it is your job to go and look for them. If you aspire to be a developer then you need to spend a lot of time searching for information yourself, studying it, and working to improve your skills.

As you are new to MVC then try to understand MVC flow and architecture of the application like why MOdel, View, Controllers folders and their purpose. Once you will know the flow then start digging into that how return data from controller to view and vice versa etc. Here are the couple of links that may help you:

Do. google, you will get lots of tutorials sites like asp.net, w3schools,tutorialspoint, codeproject etc.
But one think that keep in your mind, you have to practice yourself in continue basis.Only you can help or improve yourself.

Has anyone looked at combining the above as a quick method of providing a Win10 Metro UI interface to a website?

I have incorporated the Metro-UI News Portal Template into a standard ASP.NET MVC project. It is giving me a jQuery error when I run it. However, if I just select continue, the web page is displayed correctly. Hmmm?

Hi All,

I am saving a word document in database as bytes and in another column I am saving the file name, I am providing a link button or an anchor tag for the user to select when the user clicks on it the user should be able to see the file opened in another browser window.

Can you anybody please help me on it a little bit any code snippet, a link or even a suggestion would help me a lot. I am also searching but asking if somebody can guide me in a right direction.

Thanks in advance.

Thanks,

Hi I tried this way but it shows me the document in binary format

protected void Page_Load(object sender, EventArgs e)
        {
            Investigator _objInvestigator = new Investigator();
            InvestigatorService _objinvestigatorService = new InvestigatorService();

            int InvestigatorId;
            InvestigatorId = ((Session["InvestigatorId"] != null) && int.TryParse(Session["InvestigatorId"].ToString(), out InvestigatorId)) ? InvestigatorId : 0;
            _objInvestigator = _objinvestigatorService.GetByInvestigatorId(InvestigatorId);
            if (_objInvestigator != null)
            {
                if ((_objInvestigator.CvFile != null) && !string.IsNullOrEmpty(_objInvestigator.CvFileNameWithExt))
                {
                    String ext = System.IO.Path.GetExtension(_objInvestigator.CvFileNameWithExt);

                        Response.ContentType = "application/" + ext;
                        Response.AddHeader("content-length", _objInvestigator.CvFile.Length.ToString());
                        Response.BinaryWrite(_objInvestigator.CvFile);

                }
            }

        }

And this the code for link button click

protected void loadFile_Click(object sender, EventArgs e)
       {
           Response.Write(string.Format("<script>window.open('{0}','_blank');</script>", "TheFile.aspx"));
       }

Any suggestions please?

what is the file's extension? .doc or .docx

I think it is your content type that is incorrect

If the extension is .doc, the content type should be application/msword and if your extension is .docx, the content type should be application/vnd.openxmlformats-officedocument.wordprocessingml.document

indian1431-Mar-16 6:06

The content type can be three 1. doc, 2. docx and then .pdf but I think I pretty much got answer from you but if you can just give me whats the type for the pdf.
Thanks buddy. Smile | :)

Hey buddy still docx is showing binary data doesn't look good to humans man.
Here is the code, can you please let me know where did I do mistake?

Investigator _objInvestigator = new Investigator();
            InvestigatorService _objinvestigatorService = new InvestigatorService();

            int InvestigatorId;

            _objInvestigator = _objinvestigatorService.GetByInvestigatorId(InvestigatorId);
            if (_objInvestigator != null)
            {
                if ((_objInvestigator.CvFile != null) && !string.IsNullOrEmpty(_objInvestigator.CvFileNameWithExt))

Resizing Images, from Bytes[] back to bytes[]

You can add target="_blank" to you hyperlink button and set the button to navigate to a generic handler that will get the file from your database and display it.

So I'm writing a new function to resize images for my MVC App.
This time, instead of reading the disk drive, and writing back, I thought I would just take the upload file stream as bytes and pump into this function.

So the way I was doing it before, was to
Read the Image,
Create a Bitmap Canvas
Create a Graphics resized with the Image
Write the Image to the Bitmap.
Save As File

So I'm down to the last step, save as something so I can save as bytes. Before I just wrote to the disk drive, but now I want to stuff it back into the database.

Am I going about this all wrong?

This is an example off the top of my head, it's been condensed to show what I'm doing.

public static byte[] resise(byte[] pBytes)
{
   MemoryStream ms_in = new MemoryStream(pBytes);
   Image requestObj = Image.FromStream(ms_in);

   Image bitmapObj = new Bitmap(t_Width, t_Height, PixelFormat.Format24bppRgb);

   Graphics graphicObj = Graphics.FromImage(bitmapObj);
   graphicObj.DrawImage(bitmapObj, xWidth, xHeight, t_Width, t_Height);

   // I can't figure this part out, how to save a Memory Stream, so I can go byte[]
   graphicObj.Save(ms_out);

   return ms_out.ToArray();

}

I think I interpreted the Graphics Object wrong.
It's just a processor, that converts, the Bitmap is the object or image.
I don't have the whole thing working yet, but I think it will, but I do see bytes in the output.
And I think I used using correctly on the Graphics processor, not sure about disposing of some of the other stuff.

It's been years since I wrote an image resizer, but I did it in VB last.

public static model_image_object smtpHeader_resize(string pName, byte[] pBytes)
{
    // Target Width / Height
    // Headers are 650px in width, and suppose to be 146px in height
    const int t_Width = 650;
    const int t_Height = 146;

    // Create the return Image Object
    model_image_object pResult = new model_image_object();
    MemoryStream ms_out = new MemoryStream();
    MemoryStream ms_in = new MemoryStream(pBytes);
    Image requestObj = Image.FromStream(ms_in);

    // Figure out what we need to do to resize this image
    int oWidth = requestObj.Width;
    int oHeight = requestObj.Height;
    int cHeight = 0;
    int cWidth = 0;

    // Create the canvas for the new reponseObj
    Image bitmapObj = new Bitmap(t_Width, t_Height, PixelFormat.Format24bppRgb);

    // Create the new response Image, that will overlay the Bitmap
    using (Graphics graphicObj = Graphics.FromImage(bitmapObj))
    {
        graphicObj.Clear(Color.Transparent);
        graphicObj.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.Default;
        graphicObj.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;

        // Calculate the new Height and Width of the Image
        if (oWidth > t_Width)
        {
            cWidth = t_Width;
            cHeight = (int)Math.Round((oHeight / (float)oWidth) * t_Width);
        }
        else if (oHeight > t_Height)
        {
            cHeight = t_Height;
            cWidth = (int)Math.Round((oWidth / (float)oHeight) * t_Height);
        }

        // Calculate how to overlay the width of the image centered
        int xLeft = (cWidth - t_Width) / 2;
        int xTop = (cHeight - t_Height) / 2;

        // Create the new Image Object
        graphicObj.DrawImage(bitmapObj, xLeft, xTop, t_Width, t_Height);

        // Create a new MemoryStream to Save the Image to<br />
        bitmapObj.Save(ms_out, ImageFormat.Png);
    }

    // Program the pResult
    pResult.Data = ms_out.ToArray();
    pResult.Name = pName;
    pResult.Type = "image/png";
    pResult.Size = new model_image_type_size();
    pResult.Size.Height = cHeight;
    pResult.Size.Width = cWidth;

    return pResult;
}

[Now it works], but needs advice on disposing

I case your reading this, to figure out how to do it, this is what worked for me, but it needs more refinement such as disposing.

So I guess I'm down to just disposing of the object, but I need to make sure I preserve 1 of them to pass back to the Controller.

public static model_image_object smtpHeader_resize(string pName, byte[] pBytes)
{
    // Target Width / Height
    // Headers are 650px in width, and suppose to be 146px in height
    const int t_Width = 650;
    const int t_Height = 146;

    // Create the return Image Object
    model_image_object pResult = new model_image_object();
    Stream stream_in = new MemoryStream(pBytes);
    MemoryStream ms_out = new MemoryStream();

    // Create an Image so we can get the image parameters
    Image image_in = Image.FromStream(stream_in);

    // Write this to the drive and visually inspect it
    image_in.Save(System.Web.HttpContext.Current.Server.MapPath("~/Images/smtp/image_in.png"));

    // Figure out what we need to do to resize this image
    int oWidth = image_in.Width;
    int oHeight = image_in.Height;
    int cHeight = 0;
    int cWidth = 0;

    // Create the canvas for the new resized image
    Bitmap bitmapObj = new Bitmap(t_Width, t_Height, PixelFormat.Format24bppRgb);            

    // Create the new graphics, that will overlay the Bitmap Canvas
    using (Graphics graphicObj = Graphics.FromImage(bitmapObj))
    {
        graphicObj.Clear(Color.Transparent);
        graphicObj.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.Default;
        graphicObj.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.High;

        // Calculate the new Height and Width of the Image
        if (oWidth > t_Width)
        {
            cWidth = t_Width;
            cHeight = (int)Math.Round((oHeight / (float)oWidth) * t_Width);
        }
        else if (oHeight > t_Height)
        {
            cHeight = t_Height;
            cWidth = (int)Math.Round((oWidth / (float)oHeight) * t_Height);
        }

        // Calculate how to overlay the width of the image centered
        int x = (cWidth - t_Width) / 2;
        int y = (cHeight - t_Height) / 2;

        // Create the new Image Object
        graphicObj.DrawImage(image_in, x, y, t_Width, t_Height);
        graphicObj.Save();
    }            

    // Now write the image_out to test it and make sure it's correct<br />
    bitmapObj.Save(System.Web.HttpContext.Current.Server.MapPath("~/Images/smtp/bitmap_out.png"));

    // Create a new MemoryStream to Save the Image to
    bitmapObj.Save(ms_out, ImageFormat.Png);            

    // Program the pResult
    pResult.Data = ms_out.ToArray();
    pResult.Name = pName;
    pResult.Type = "image/png";
    pResult.Size = new model_image_type_size();
    pResult.Size.Height = cHeight;
    pResult.Size.Width = cWidth;

    return pResult;
    }

An Ajax Control is working on local machine not working on Server when deployed

indian14327-Feb-16 14:32

Re: An Ajax Control is working on local machine not working on Server when deployed

27-Feb-16 14:32

Hi All,

I am working with Telerik Ajax Controls called RadWindow, RadBinaryImage, RadAsyncUpload and RadImageEditor, all these are working fine on my local machine, when I deploy app on the server, the controls are not working. These controls are in a separate page which actually opens as a Popup. And when I deploy the Application on the Server it stops working I am not sure is it because of the Version mismatch of the Telerik Controls. Is there any way to validate it? or is there any way I can Xcopy the application files and set that my application should use Local copy of the Telerik dlls.
I doubt it should the same reason because sometime before it gave the similar problems because of the mismatch. Thank you.

Thanks,

Abdul Aleem

Make sure the appropriate .NET also exists on the server.

You also most likely need to modify the folder permissions on the server. Make sure that IIS_IUSRS (or the service account, if appropriate) has the appropriate permissions per folder, I'm sure that the Telerik documentation has those details.
