hi thanks for that

one question, im trying to add multiple slides but for some reason its not adding them my code is this

protected void Page_Load(object sender, EventArgs e)

{

Session["style"] = "design1.ppt";

Presentation dstPres = new Presentation(@Server.MapPath("")+"\\creationtest.ppt");

try

{

string[] selectedPPTs = Session["selectedSlides"] as string[];

string sqlIn = "";

if (0 != selectedPPTs.Length)

{

for (int x = 0; x < selectedPPTs.Length; x++)

{

sqlIn += selectedPPTs[x] + ",";

Response.Write("file id = " + selectedPPTs[x] + "
");

}

sqlIn = sqlIn.Substring(0, sqlIn.Length - 1);

try

{

//con = new SqlConnection(ConfigurationSettings.AppSettings["asposeslideDbConn"]);

con = new SqlConnection("Data Source=192.168.50.10;Initial Catalog=asposeslidetest;Persist Security Info=True;User ID=ih;Password=A1");

cmd = new SqlCommand("sp_get_selected_slides", con);

cmd.CommandType = CommandType.StoredProcedure;

SqlParameter objParam1;

objParam1 = cmd.Parameters.Add("@inclaus", SqlDbType.NVarChar);

objParam1.Direction = ParameterDirection.Input;

objParam1.Value = sqlIn;

if (con.State.Equals(ConnectionState.Closed))

{

con.Open();

SqlDataReader srdr = cmd.ExecuteReader(CommandBehavior.CloseConnection);

if (null != Session["style"])

{

}

while (srdr.Read())

{

Presentation srcPrs = new Presentation(@Server.MapPath("")+"\\uploaded_ppts\\"+srdr[2]);

CloneSlideWithNotes(srcPrs, Convert.ToInt32(srdr[1]), dstPres);

}

}

}

catch (Exception dbQueryEx)

{

Response.Write("problem with query on line 74 " + dbQueryEx.Message + "sql in = " + sqlIn);

}

}

}

catch (Exception pgLoadEx)

{

Response.Write("prolem exception fired on line 80"+ pgLoadEx.Message);

}

}

protected void CloneSlideWithNotes(Presentation srcPres, int srcSlidePosition, Presentation dstPres)

{

try

{

Slide srcSld;

srcSld = srcPres.GetSlideByPosition(srcSlidePosition);

if (srcSld == null)

return;

int dstSldPosition;

dstSldPosition = dstPres.Slides.LastSlidePosition + 1;

//Clone slide now, we have all the necessary parameters

Slide dstSld;

dstSld = srcPres.CloneSlide(srcSld, dstSldPosition, dstPres, new SortedList());

//Now below is the code to copy srcSld notes to dstSld notes

//Add notes to dstSld and clear all paragraphs

dstSld.AddNotes();

dstSld.Notes.Paragraphs.Clear();

//Finally add all the pargraphs in notes of sldSrc into the notes of dstSld

foreach (Paragraph srcPara in srcSld.Notes.Paragraphs)

{

//Create the replica of srcPara

Paragraph dstPara = new Paragraph(srcPara);

//Add this Replica to dstSld.Notes.Paragraphs

dstSld.Notes.Paragraphs.Add(dstPara);

}

}

catch (Exception CloneSlideEx)

{

Response.Write("error in cloneslide method " + CloneSlideEx.Message);

}

}

thanks

Make sure you are passing valid parameter value of srcSlidePosition in **CloneSlideWithNotes()

Because if there is no slide at position srcSlidePosition in srcPres, then, srcSld will be null and method will return without doing anything, see the code below

Slide srcSld;
srcSld = srcPres.GetSlideByPosition(srcSlidePosition);

if (srcSld == null) //if it is null, it will not do any thing and return
    return;

Hi Shakeel

I now have it working to a certain degree, however for some reason when i add the notes its putting them on the a new slide.

here is my code

try

{

Presentation clonePres = new Presentation(@Server.MapPath("") + "\\uploaded_ppts\\" + srcPres);

Slide srcSld;

srcSld = clonePres.GetSlideByPosition(srcSlidePosition);

if (srcSld == null)

return;

int dstSldPosition;

dstSldPosition = dstPres.Slides.LastSlidePosition + 1;

Slide dstSld = dstPres.AddEmptySlide();

clonePres.CloneSlide(srcSld, dstSldPosition, dstPres, new SortedList());

dstSld.AddNotes();

dstSld.Notes.Paragraphs.Clear();

//add all the pargraphs in notes of sldSrc into the notes of dstSld

foreach (Paragraph srcPara in srcSld.Notes.Paragraphs)

{

Paragraph dstPara = new Paragraph(srcPara);

dstSld.Notes.Paragraphs.Add(dstPara);

}

}

catch (Exception CloneSlideEx)

{

Response.Write("error in cloneslide method " + CloneSlideEx.Message);

}

thanks in advance

Please update your code like this.

int dstSldPosition;
dstSldPosition = dstPres.Slides.LastSlidePosition + 1;

//Your commented line
//Slide dstSld = dstPres.AddEmptySlide();

clonePres.CloneSlide(srcSld, dstSldPosition, dstPres, new SortedList());

//The line added by me
dstSld = dstPres.GetSlideByPosition(dstSldPosition);
dstSld.AddNotes();

great thanks seems to work now

one small thing though i added

Slide dstSld;

dstSld = dstPres.GetSlideByPosition(dstSldPosition);

can you tell me what would cause this error

The process cannot access the file 'C:\Inetpub\wwwroot\apose2\creationtest2.ppt' because it is being used by another process

thanks

Hello Andrew,

Such an exception occurs, when you try to read/write the file, which is being written by some other process.

In your case, I think, you are reading creationtest2.ppt and then writing it back and while doing so, you created another process that tried to read it while it was being written by the previous process.

If you want to send the output file to user on the web, then you can simply use this code snippet

Response.Clear();
Response.ContentType = "application/vnd.ms-powerpoint";
Response.AppendHeader("Content-Disposition", "attachment; filename=demo.ppt");
Response.Flush();

// Send the file
System.IO.Stream st = this.Response.OutputStream;
pres.Write(st);

Response.End();
