    <p>I have internal error at the EdsDownload. I'am using EOS 1100D without sdcard. The Canon sample code (CameraContorol) can download image. Used SDK: 2.13 and 2.12 (i have same problem with both). Please help me.<br> Note: the "picture000x.jpg" size is 0 after the run (because the EdsCreateFileStream call).</p> <p><b>My code output</b>:<br> Device name: Canon EOS 1100D.<br> GET PICTURE:<br> 'Call' handleObjectEvent.<br> Event: kEdsStateEvent_JobStatusChanged,<br> Event code: 770<br> <br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Internal error at EdsDownload.<br> stream != NULL<br> Download h.ended.<br> Press key to quit.<br></p> <p><b>My code</b>:</p> <pre><code>bool getPictureEnabled = false, hasCamera = false;

    1. COThat's a pretty hefty block of code you've got there! You may want to consider condensing it down to just show the DownloadImage function in order to highlight the lines at the end that cause the error, it can be tough to parse though lots of code just to get to the meat of an issue.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
