Problem with adding text to a existing PDF

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, 

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.

	Hi! You're mixing DA-functions and "not-DA-functions". If you're opening the file with DAOpenFile then you should select your page with DAFindPage. My advice for you is: Don't use the DA-functions first. Earlier versions of QuickPDF had sometimes few memory problems. With the DA-functions these behaviors should be avoided but with the current version this shouldn't be necessary anymore. So please no mixing! Cheers, Ingo

	Thanks for the reply, but the version we are using is 4.42.1.1, is this version safe enough to use with non DA functions, or would there be memory problems.

	Hi! You'll have a lot of probs in the future! More and more... All new pdf-specs aren't supported in your very old version. You should update as quick as possible. In your version there are a lot of memory probs. Cheers, Ingo
