I am using v 5.22
When I try to use the DAGetPageImageList I get an error
"Object reference not set to an instance of an object"
I am using C# to write my code using VS.NET 1.1
int fileID=fileID=qp.DAOpenFile(strFileName,""); int pageID=qp.DAFindPage(fileID,1); int imageListID=qp.DAGetPageImageList(fileID,pageID); Get the error on the line above.
Both fileID and pageID are non zero
Not sure if this is a bug in v5.22 or am I doing something wrong here. Any help appreciated.

andrewf22,
this may be a bug in QuickPDF library. If it is related to 5.22 I cannot confirm because I have never worked with DA* functions of this library.
If you want that I take a look on your program (demo is ok as well) please sennd an email to support(at)quickpdf.org. But I warn you that I have a lot of bugs lately and I can for the moment only confirm this problem.
VS.NET sample works fine with me.
Best regards, Marian

| Hi Marian Thanks for looking into this for me. I have sent the code to your email address. Also is there any chance that this bug might have popped up in v5.22. Before this I was using v4.28 which diddnt have these DA Image functions. Any chance I could get my hands on a previous version to verify if it occurs there also or are you going to check this out when you confirm the bug ? |

I haven't tested, but this line looks a bit funky. Also, did you remember to unlock the library first? |

Oops my mistake.
By mistake I mean not in code but typing the code in the post here.
Below is the actual code which I am using
iSED.QuickPDF qp = new iSED.QuickPDFClass();
if (qp.UnlockKey("UNLOCK KEY HERE") == 0)
{ System.Diagnostics.Debug.WriteLine("iSED.QuickPDF license expired."); return ; } //GetImageProperties int fileID=0; fileID=qp.DAOpenFile(strFileName,""); if (fileID == 0) { System.Diagnostics.Debug.WriteLine("iSED.QuickPDF Could not load file."); return ; } int pageID=qp.DAFindPage(fileID,1);
if (pageID == 0) { System.Diagnostics.Debug.WriteLine("iSED.QuickPDF Could not Find Page."); return ; } int imageListID=0;
try { //** ERROR OCCURS HERE ** imageListID=qp.DAGetPageImageList(fileID,pageID); } catch(Exception ex) { System.Diagnostics.Debug.WriteLine(ex.ToString()); } if (imageListID == 0) { System.Diagnostics.Debug.WriteLine("iSED.QuickPDF Could not Find PageImageList."); return ; } |

Yes it may be the case. I have never tested the DAGetPageImageList function. It seems that you are the first one.
Can you please send me your pdf file to support(at)quickpdf.org
If yes I will give it a try.
Marian
