Hi Praveen;

     For viewing images from a File directly in your PB App, have a look at the InkPicture control in PB to help you on this. If the Image were in a Blob column, have a look at the DataWindow's TableBlob feature.

     For PDF's, I would suggest using the HyperLinkToURL() method of the PB based iNET object to help you let the O/S's default Web Browser display this for you.

Hello Praveen,

I would:

1) retrieve the byte stream and store it into a blob;
2) save the blob to a local file (image/pdf);
3) display the local file (use the PB Picture control if an image, or the MS Web Browser Ole control if a PDF)

In details:

1) convert byte stream to blob

    byte lbytes[]
    Blob lblb​
    // read the byte array from external API
    lBlobLen = UpperBound(lbytes) 
    lblb = Blob(Space(lBlobLen), EncodingAnsi!) 
    For lBytePos = 1 To lBlobLen 
        BlobEdit(lblb, lBytePos, lbytes[lBytePos], EncodingANSI!) 
    Next
    
2) save the blob to a file

    integer li_FileNum
    li_FileNum = FileOpen("myfile.jpg", StreamMode!, Write!, LockWrite!, Append!)  // same if PDF or other image formats
    FileWriteEx(li_FileNum, lblb)
    FileClose(li_FileNum)

3) display the file

    p_1.picturename = 'myfile.jpg'  // use Picture control
​  ----
    ole_1.object.navigate (sle_pdffile.text) // use MS Web Browser ActiveX

Cheers,
Marco

For the PDF, write it to a file and display it with the IE WebBrowser control. I have an example here:

For the image, I have a picture control that supports loading the image directly from a blob.

http://www.topwizprogramming.com/freecode_canvas.html

It supports bmp, gif, jpg, png, wmf, emf, and tif.

Hi Roland,

Experimenting with the free code in canvas.zip. I'm trying to do a silent print to a PDF filename with 'MicroSoft print to PDF' from the 'Print' button in the example. Using lpszOutput member of DOCINFO to specify filename; however, it is defined as a uLong in the example although internet document states this should be of type string.  Is there a way to do a silent print to filename using the StartDoc WinApi that uses the DOCINFO structure.? Or maybe some other way?

Thanks,

Mike

Save it as a temp file and then load it into a WebBrowser control.
