Invalid Pointer

[DolphinMann]

I am getting the follow message: "Error [System]: Invalid pointer." on the line:
IPXC_Document doc = convertByExtension[Path.GetExtension(fileName).ToUpper()].Convert(((PXV_Inst)viewerInstance), destFile);

When attempting to convert a DOC/DOCX file, but only those types of files with the following code segment(s). It seems that converting text/images work fine, but Office documents DOC(X)/XLS(X) do not. I'm sure there is some other type of error happening here but how would I figure out what that is?

Code: Select all

                        convertByExtension = new Dictionary<string, IPXV_ImportConverter>();

                        for (uint count = 0; count < viewerInstance.ImportConvertersCount; count++)
                        {
                            string[] extensions = viewerInstance.ImportConverter[count].Extensions.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);

                            foreach (string s in extensions)
                            {
                                if (!corePDFConversionExtensions.Contains(s.Replace("*", "").ToUpper()))
                                {
                                    corePDFConversionExtensions.Add(s.Replace("*", "").ToUpper());
                                    convertByExtension.Add(s.Replace("*", "").ToUpper(), viewerInstance.ImportConverter[count]);
                                    Logger.Log("Added: " + s.Replace("*", "").ToUpper() + " to possible PDF Conversion types", 5);
                                }
                            }
                        }

Code: Select all

                if (viewerInstance == null)
                {
                    try
                    {
                        viewerInstance = new PXV_Inst();
                        viewerInstance.Init(null, DolphinCorePDF.devKey);

                        Logger.Log("PDF Converter Object Initialized", 5);
                    }
                    catch (Exception ex)
                    {
                        Logger.Log("Error During Init for PDFTools", ex, 1);
                        int hr = Marshal.GetHRForException(ex);
                        PDFTools.LogErrMsg(hr);
                    }
                }

                if (auxInst == null)
                {
                    auxInst = (IAUX_Inst)viewerInstance.GetExtension("AUX");
                }
                            ICab AParams;
                            ICabNode AOpts;

                            string tempFileName = outputFileName;
                            AParams = viewerInstance.CreateOpenDocParams();
                            AOpts = AParams.Root;
                            AOpts.SetBool("NoProgress", true);
                            AOpts.Flags &= ~((uint)AFS_OpenFileFlags.AFS_OpenFile_AllowUI);

                            IAFS_Inst fsInst = (IAFS_Inst)viewerInstance.GetExtension("AFS");
                            IAFS_Name fileToOpen = fsInst.DefaultFileSys.StringToName(fileName);
                            int openFlags = ((int)AOpts.Flags);
                            IAFS_File destFile = fsInst.DefaultFileSys.OpenFile(fileToOpen, openFlags);
                            IPXC_Document doc = convertByExtension[Path.GetExtension(fileName).ToUpper()].Convert(((PXV_Inst)viewerInstance), destFile);
                            doc.WriteToFile(tempFileName);
                            doc.Close();
                            doc = null;
                            destFile.Close();
                            destFile = null;

I should also add that if I do not load the document via code, but via the standard "Open File" dialog in the front-end the same document loads and converts. It is something with my method of opening programmatically

Hello DolphinMann,

Do you have a MSOffice >= 2007 preinstalled on your machine?
Also, try simplifying your code:

Code: Select all

string extension = "conv.imp.office.doc";
PDFXEdit.IPXV_ImportConverter cov = null;
for (int i = 0; i < pdfCtl.Inst.ImportConvertersCount; i++)
{
	cov = pdfCtl.Inst.get_ImportConverter((uint)i);
	if (cov.ID == extension)
		break;
}
if ((cov != null) && (cov.ID == extension))
{
	PDFXEdit.IAFS_Inst fsInst = (PDFXEdit.IAFS_Inst)pdfCtl.Inst.GetExtension("AFS");
	PDFXEdit.IAFS_Name name = fsInst.DefaultFileSys.StringToName(@"C:\Users\polar_000\Documents\S-1.docx");
	int openFileFlags = (int)(PDFXEdit.AFS_OpenFileFlags.AFS_OpenFile_Read | PDFXEdit.AFS_OpenFileFlags.AFS_OpenFile_ShareRead);

	PDFXEdit.IAFS_File destFile = fsInst.DefaultFileSys.OpenFile(name, openFileFlags);
	PDFXEdit.PXV_FmtCheckResult ret = cov.CheckFormat(pdfCtl.Inst, destFile);
	PDFXEdit.ICab cab = pdfCtl.Inst.GetFormatConverterParams(true, extension);
	PDFXEdit.IPXC_Document doc = cov.Convert(pdfCtl.Inst, destFile);
	pdfCtl.OpenDocFrom(doc);
}

Alex,

Thank you. That indirectly did help! I am not using the PDFControl as this is a background application where I just create a viewer instance but it still worked.

It seems the problem was with my "openFileFlags", it simply does not like the way I was using the suppress UI flag. Is there any way to get it so the conversion popup window does not display?

Hello DoplhinMann,

There is no way to hide the office conversion window - you can use the search on forums for similar topic.

Cheers,
Alex
