I am trying to add some text to a existing PDF using a C# (.NET 1.1 framework)  application. Below is my code snippet. But the generated PDF does not contain the text written, but contains the contents of the source PDF as well as a blank new page.

 

string strSource = @"D:\Test\1231_001.pdf";   
string strDest = @"D:\Test\outputsample.pdf";

pdf = new QuickPDFClass();   
if (pdf.Unlocked() == 0)
{
 nResult = pdf.UnlockKey("My key");
}
DA_HANDLE = -1;//op_add
DA_HANDLE = pdf.DAOpenFile(strSource, "");
if (DA_HANDLE <= 0)
{
 MessageBox.Show("Error occured while opening");
 return;
}

nResult =pdf.DANewPage(DA_HANDLE);
nResult =pdf.SelectPage(pdf.PageCount());
pdf.SetTextColor(1,0,0);
pdf.DrawText(10,10,"Email Subject");
nResult= pdf.DASaveAsFile(DA_HANDLE,strDest);
if (nResult==1)
{
 MessageBox.Show("Saved");
}
pdf.DACloseFile(DA_HANDLE);
DA_HANDLE = 0;

 

Any help with this regard is greatly appreciated.

 

Thanks in advance.
