We are currently using Syncufsion version 4.4 (exact dll file version is 4.401.0.54), and are facing a compatibility issue with Windows 2008. Syncfusion dlls in Windows 2008 environment runtime, throw "misisng iprop.dll" error, i.e. unable to automatically pick up the dll from the syswow64 in Windows 2008, instead of system32 folder.
From the release notes, we see that fix for this bug has been introduced in 22.214.171.124. (Bug. # 11375).
We tried to download the evaluation version of 126.96.36.199, but were unable to install, because the evaluation unlock key could not be retrieved for this version (the setup points to www.syncfusion.com/pdc ; - a broken link). The evaluation key is available only for the latest version 188.8.131.52
We installed the evaluation version of 184.108.40.206 using the evaluation key from the website.
The functionality which we currently use in version 4.4 is:
a) Use Syncfusion.XlsIO to create "xls" files from Microsoft Excel Spreadsheet XML (note: this should not be confused with OOXML), with complex styles, Form Controls, chart images etc.
b) Manipulating fonts/ border styling on Syncfusion.XlsIO.XlsWorkbook object, created from Microsoft Excel Spreadsheet XML, and saving the object as a "DLS"
c) Load PDFLogicDocument from the DLS, manipulating its sections, and saving it as a "pdf" file
... using the namespaces within Syncfusion.XlsIO.Base, Syncfusion.Core, Syncfusion.DLS.Base, Syncfusion.Pdf.Base, Syncfusion.Compression.Base .
Our expectation with version 8.2/6.4 is to preserve this functionality, with the same code, (not compromising on quality of the output XLS/PDF document) and also work on x64 platform like Windows 2008 without throwing the iprop.dll error.
In 8.2 the classes like PDFLogicDocument etc. which we use in 4.4 have been moved to a Legacy dll.
Though the code compiles after adding the Legacy Dll, the output PDFs after Excel->DLS->PDF conversion, is compromised when it comes to using fonts like MS PGothic, SimSun etc. (Japanese/Chinese characters show up as junk characters despite changing the font to MS PGothic, MS PMincho or SimSun in the XlsWorkbook before conversion to DLS->PDF).
We are unable to see how our existing code works with version 6.4, in which the "Missing iprop.dll" fix was just introduced.
Since this version earlier than 8.2, and closer to 4.4, can we expect the namespaces we use to be same and Spreadhseet XML->Excel->DLS->PDF functionality unaffected?
Please let us know if we can test the above scenario in version 6.4
