Display PDF from memory stream using ActiveX

[fmassey]

Hello,

I'm currently evaluating the ActiveX PDF display control for possible inclusion in our products. One of the main caracteristic we are looking for is the ability to display a PDF from an instance that resides in memory instead of a file on disk. This is to fulfill a security requirements we have.

Is this possible with PDF XChange ActiveX control?

Thanks for any imput/thoughts on this.

UPd: Oh, missed the post by huyltx (dec 22) on this. It seems built 41.9 will contain that feature. Is this out yet?

This feature added for new build 41.1 but undocumented now (documentation will be updated in the future):
for open/save from/to memory stream without placing content into temp file you should
1. SetProperty("Documents.UseStreamsDirectly", "True", 0)
2. DoVerb(NULL, "OpenDocument", StreamObj, ..);
// after this, stream object will be "captured" by AX and can be used for saving document into this stream object in the future
// that is:
3. DoVerb(NULL, "SaveDocument", NULL, ..); // save changes to "captured" stream by default
The "captured" stream object will be released when document closes.

If:
"Documents.UseStreamsDirectly" == "false" // by default
then all content from stream object will be placed by AX - into temporary file before open.
In this case AX releases this stream object after open and "don't remember" about him.
