Microsoft.Office.Interop.PowerPoint.Shape objShape;
Microsoft.Office.Interop.PowerPoint.SlideShowWindows objSSWs;
Microsoft.Office.Interop.PowerPoint.SlideShowTransition objSST;
Microsoft.Office.Interop.PowerPoint.SlideShowSettings objSSS;
Microsoft.Office.Interop.PowerPoint.SlideRange objSldRng;
//Create a new presentation based on a template.
objApp = new Microsoft.Office.Interop.PowerPoint.Application();
objApp.Visible = MsoTriState.msoTrue;
objPresSet = objApp.Presentations;
objPres = objPresSet.Open(strTemplate,
MsoTriState.msoFalse, MsoTriState.msoTrue, MsoTriState.msoTrue);
objSlides = objPres.Slides;
//Build Slide #1:
//Add text to the slide, change the font and insert/position a

objSlide = objSlides.Add(1, Microsoft.Office.Interop.PowerPoint.PpSlideLayout.ppLayoutTitleOnly);
objTextRng = objSlide.Shapes[1].TextFrame.TextRange;
// objTextRng.Text = "FAME Presentation";
objTextRng.Font.Name = "Comic Sans MS";
objTextRng.Font.Size = 25;
foreach (var ar in arr)

objTextRng = objSlide.Shapes[1].TextFrame.TextRange;
// objTextRng.Text = "FAME Presentation";
objTextRng.Font.Name = "Comic Sans MS";
objTextRng.Font.Size = 25;
string[] str = (string[])ar;
strPic = str[0];
objSlide.Shapes.AddPicture(strPic, MsoTriState.msoFalse, MsoTriState.msoTrue,

//and apply various color schemes and shadows to the text effect.
}
}
catch (Exception ex)
{
throw ex;
}
当我运行这一点，每一件事情是工作在本地主机很好，但是当我举办这个appilcaion IIS7它抛出异常PowerPoint无法打开的文件。
所以我的想法是最好添加响应头，于是我也跟着下面的code
when i Run this, every thing is working fine in localHost, but when i host this appilcaion IIS7 it Throwing exception PowerPoint could not open file. so what i thought is better to add Response Header, so i followed the below code
// dt是数据表名称这containt，图片的路径保存当我点击SaveImage
// dt is the DataTable Name which containt, path of Images saved when i click on SaveImage
GridView1.AllowPaging = false;
GridView1.DataSource = dt;
GridView1.DataBind();////////write this code only if paging is enabled.
Response.Clear();
Response.AddHeader("content-disposition", "attachment;filename=FileName.ppt");///////for text file write FileName.txt
Response.Charset = "";
// If you want the option to open the Excel file without saving than
// comment out the line below
// Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ppt";//for text file write vnd.txt
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
在这里，我可以添加图像PPT，但他们在同一个幻灯片和图像相互重叠。
here i can add Images to PPT, but they are in same slide,and the images are overlapping each other.
任何一个可以帮助我，有急事请。
any one help me it's Urgent please.
推荐答案
服务器（如ASP.NET）不是由MS支持使用互操作 - 看到的 http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2
Using Interop on the server (like ASP.NET) is NOT supported by MS - see http://support.microsoft.com/default.aspx?scid=kb;EN-US;q257757#kb2
由于Windows Vista中引入MS几个与安全相关的措施，prevent Windows服务从做桌面式的东西......这意味着你将不得不绕过几个保安措施，以得到它的工作（不推荐！）。
Since Windows Vista MS introduced several security-related measures which prevent a Windows Service from doing "desktop-like" things... which means you would have to circumvent several security measures to get it to work (NOT recommended!).
要处理的PPT在服务器方案中有一些选项（免费的和商业）那里：
To deal with PPT in a server-scenario there are some options (free and commercial) out there:
有一个自由选择（尽管较新的PPTX格式只！）例如的 2的OpenXML从MS 的。
A free option (though for the newer pptx format only!) is for example OpenXML 2 from MS.
一个商业的选择是 Aspose.Slides 它可以处理旧的（PPT ）和新（PPTX）格式。
A commercial option is Aspose.Slides which can handle old (PPT) and new (PPTX) format.
