Hi RRogers,

think you've got this issue while mixing DA- and non-DA-functions.

In one instance these two kinds of functions shouldn't be mixed.

For further help:

The code part before RenderPageToFile could be more interested than

the part after ;-)

Cheers and welcome here,

Ingo

hi RRogers - I'm new to the forum but interested in your post.

Could you post the code (or a cutdown version) that populated the QP object before you wrote it out to file. My initial guess is that QP is writing a feature to disk that is not supported by the QP.DAOpenFile. Also, you may not need to specify the pswd, as you didn't specify one when calling RenderPageToFile....

I am using the ActiveX QuickPDF Library with following code in C#.

I am getting Error: "Invalid Structure, file damaged" when it tries to open the file

that I rendered to disk.

I can open the file in windows explorer but not with the DAOpenFile command.

Why does it think the file is damaged?

switch

(QP.RenderPageToFile(300, i, 9, HTMLFileName))

{

case 0:

MessageBox.Show("The page could not be rendered. Check the value of the FileHandle and PageRef parameters.");

break;

case 1:

QPInstance = QP.DAOpenFile(HTMLFileName, pswd);

if (QPInstance == 0)

{

LastError = QP.LastErrorCode();

ShowQPDFError(LastError);

}

else

{

MessageBox.Show("Instance = " + QPInstance);

}

break;

case 2:

MessageBox.Show("The file could not be written to disk");

break;

}
