Using PDF-XChange Viewer SDK from WPF

[AndreaCCS]

Do you have any examples of embedding a viewer in a WPF form.

Hi, Andrea.

See the simple example in the attached archive and look to:

Thanks for this. Do you have any plans to develop a native WPF component or a native Windows forms component?

Thanks this sample works well. The documentation (PDF-XChange Viewer SDK) states that when you call for example OpenDocument it should return a result

HRESULT OpenDocument(BSTR SourceFileName,BSTR OpenPassword,LONG* ID,LONG Flags);

But the function in the sample code is a void function so how can I ensure the file is opened properly (Or does it just throw an exception instead or returning an error). Is this the case for all the functions?

I would also like to say thanks for your (very) speedy response to my questions so far.

Hello Andrea,

Taken directly from the manual:

Code: Select all

Return  Value
Returns S_OK if successful, or an error value otherwise. To obtain the text description of a
received error code, use GetTextFromResult.

where S_OK is the generic HRESULT for success.

Best,
Stefan

I agree that is what it says in the manual but from C# all functions have void types e.g
void AxCoPDFXCview.OpenDocument(string sourceFileName)

I have looked at your examples more thoroughly now and I think if the function fails it throws an exception which has to be handled instead of returning a result.
