cannot write a pdf file: "invalid date string, after time"

[paolagumi]

Hello,
I've just bought Spire Office 6.6 license and downloaded the 6.6 version from your site, as I do every year.

Every works fine in:
- web sites, in debug and also published on servers;
- in window form applications and class libraries if I execute them in debug or from my p.c.,

But if I execute a class or a window form application on a server (windows server 2016 and windows server 2003...) the spire dlls do not work: the pdf file is not being created and this error is generated: "Invalid date string, after time". I removed every instruction from my code referred to date and time, but nothing changes.
Then, I also removed each instruction of spire.doc/pdf from my code, I only left a "new document()" and a "save as pdf instruction, to save an empty document, but nothing, the error still remains.
I'm sending you my code in attachment.
Can you pleae help me?
thank you,
kind regards,
Paola

Hello Brian,
in the meantime I found a solution, looking for in your forum:
in vb it's sufficient adding these instructions in our code:

Imports System.Globalization.CultureInfo (I already had it)
Imports System.Threading (added)

----
Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture
Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture

the original instructions in C that I found are:
using (var memStream = new MemoryStream())
{
var uiCulture = Thread.CurrentThread.CurrentUICulture;
var culture = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentUICulture = CultureInfo.InvariantCulture;
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
doc.SaveToStream(memStream);

Thread.CurrentThread.CurrentUICulture = uiCulture;
Thread.CurrentThread.CurrentCulture = culture;
return memStream.ToArray();
}
Basically, we only need the two "thread" statements.

So, my w.f. applications and classes now run correctly and produce pdf documents also if run on servers.
Just a question: is it possibile that since this new versione we have to use the Net4.0, instead the Net4.0 client profile that I'ìve always used also on servers....?
thank you and kind regards,
Paola

Hello Paola,

Thanks for your feedback. I am glad to hear that you have found a solution.

Besides, our Spire.Office provides both NET4.0 dlls and NET4.0 Client Profile dlls. Which dlls should be referenced depends on your project target framework. If your project target framework is NET4.0 Client Profile, then you should reference the NET4.0 Client Profile dlls.
