Trouble with SaveToHttpResponse

[whittenmike807]

Everything I open a generated ppt, keeps coming up corrupt.

Here is the code I am using: (I'm doing this with razor c#)

Code: Select all

@using System;
@using System.Drawing;
@using System.Web.Mvc;
@using Spire.Presentation;
@using Spire.Presentation.Drawing;


@{
    var companyLogoFileName = "";
    if (IsPost) {
        string companyName = Request["companyName"];
        string objectiveValue = Request["txtObjective"];
        string solutionValue = Request["txtSolution"];
        string resultValue = Request["txtResult"];
        string marketName = "Nashville";
       

        var companyLogoFileSavePath = "";
        var uploadedCompanyLogoFile = Request.Files[0];
        companyLogoFileName = Path.GetFileName(uploadedCompanyLogoFile.FileName);
        companyLogoFileSavePath = Server.MapPath("~/App_Data/UploadedFiles/" + companyLogoFileName);
        uploadedCompanyLogoFile.SaveAs(companyLogoFileSavePath);
       

        Presentation ppt = new Presentation("c:\\temp\\CaseStudyTemplateTest.pptx", FileFormat.Pptx2010);

        string marketLogo = "c:\\temp\\logos.png";
        RectangleF marketLogoRect = new RectangleF(5, 145, 135, 232);
        ppt.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, marketLogo, marketLogoRect).Line.FillType = FillFormatType.None;

        System.Drawing.Image img = System.Drawing.Image.FromFile(companyLogoFileSavePath);

        var ratioX = (double)130 / img.Width;
        var ratioY = (double)101 / img.Height;
        var ratio = Math.Min(ratioX, ratioY);

        var newWidth = (int)(img.Width * ratio);
        var newHeight = (int)(img.Height * ratio);

        var positionX = (int)((144 - newWidth) / 2);
        var positionY = (int)((116 - newHeight) / 2);

        RectangleF companyLogoRect = new RectangleF(positionX, positionY, newWidth, newHeight);
        ppt.Slides[0].Shapes.AppendEmbedImage(ShapeType.Rectangle, companyLogoFileSavePath, companyLogoRect).Line.FillType = FillFormatType.None;

        IAutoShape shape = ppt.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(0, 117, 144, 279));
        shape.Fill.FillType = FillFormatType.Solid;
        shape.Fill.SolidColor.Color = Color.FromArgb(158, Color.White);
        shape.Line.FillType = FillFormatType.None;

        IAutoShape companyNameText = (IAutoShape)ppt.Slides[0].Shapes[0];
        IAutoShape objectiveText = (IAutoShape)ppt.Slides[0].Shapes[1];
        IAutoShape solutionText = (IAutoShape)ppt.Slides[0].Shapes[2];
        IAutoShape resultText = (IAutoShape)ppt.Slides[0].Shapes[3];
        IAutoShape marketNameText = (IAutoShape)ppt.Slides[0].Shapes[4];

        companyNameText.TextFrame.Text = companyName.ToUpper();
        objectiveText.TextFrame.Text = objectiveValue;
        solutionText.TextFrame.Text = solutionValue;
        resultText.TextFrame.Text = resultValue;
        marketNameText.TextFrame.Text = marketName.ToUpper();

        //ppt.SaveToFile("c:\\temp\\ExportedPowerpoint-3102014.pptx", FileFormat.Pptx2010);

        ppt.SaveToHttpResponse("httpResponse.pptx", FileFormat.Pptx2010, HttpContext.Current.Response);

        //File.Delete(companyLogoFileSavePath);

Hello,

Thanks for your inquiry.
I have reproduced your issue that opening the document throw an error (I upload the error image) and posted it to our dev team. Once there are any processes, we will let you know.
Did you get the same information? If not, please provide the information of the error you met in detail.

Best Regards,

Is there an update on this?

I'm wanting to purchase this software, but I need it to save to the Http Response

[Betsy]

Hello,

After investigation, please add the following code after SaveToHttpResponse method:

Code: Select all

HttpContext.Current.Response.End();

Now you can open the document normally.
Please feel free to contact us if there are any questions.

Well, I'm almost there.


So I added that line to the end of the SaveToHttpReponse, and when I open the file I still get the repair pop-up.

But, If I click repair it will load fine.

Anything else?

Hello,

It would be very helpful if you provide your sample files(CaseStudyTemplateTest.pptx and logos.png ) for our testing. And we may work out the solution for you ASAP.

Thanks,
