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;

}

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....

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
