Hey,
I have to load a basic pdf with text forms and fill in these forms. Therefore I have to load the basic pdf a couple of times.
Within this loop, I use some a new operator for a parser class. This leads to an error with the OpenDocumentFromFile function although this has nothing to with the loaded Doc. .
I can also reproduce the error forcing the garbage collection to do its work. It seems to me, the OpenDocumentFromFile function has some memory problems when invoked several times within a loop.
Here is the the code:
private void btn_test_Click(object sender, EventArgs e)
{
m_Inst = new PXV_Inst();
m_Inst.Init();
IPXC_Inst pxcInst = (IPXC_Inst)m_Inst.GetExtension("PXC");
IPXC_Document Doc;
// iterate
for (int zz = 0; zz< 100; zz++)
{
Doc = pxcInst.OpenDocumentFromFile("D:\\Entwicklung\\FieldsModifySample\\test.pdf", null);
PDFXEdit.IPXC_FormField _anmeldenummer = Doc.AcroForm.GetFieldByName("Anmeldenummer");
Doc.Close();
System.GC.Collect();
}
}
Do you have any ideas solving this problem?
Regards,
Michael

Hi Michael,

Do not call new / Init multiple times.

Hey,
there isn't any new or init in the loop...

Re: Problems with pxcInst.OpenDocumentFromFile
Hi,
But is in button click.
Anyhow, try placing the following line inside the loop:
IPXC_Document Doc;
p.s.
Not official support nor C# guy.

Hi Michael.
Please try this one:
PS: thanks to Zarko for the good tip...

Please try this one:
Code: Select all
// somewhere inside the Form::Init()
m_Inst = new PXV_Inst();
m_Inst.Init(....);
.....
private void btn_test_Click(object sender, EventArgs e)
{
IPXC_Inst pxcInst = (IPXC_Inst)m_Inst.GetExtension("PXC");
for (int zz = 0; zz < 100; zz++)
{
{ // set additional scope as 'tip' for GC
IPXC_Document Doc = pxcInst.OpenDocumentFromFile("D:\\Entwicklung\\FieldsModifySample\\test.pdf", null);
PDFXEdit.IPXC_FormField _anmeldenummer = Doc.AcroForm.GetFieldByName("Anmeldenummer");
Doc.Close();
Doc = null;
}
if (((zz + 1) % 5) == 0) // each 5th doc
{
System.GC.Collect();
System.GC.WaitForPendingFinalizers();
}
}
}
