powerpoint saga

[bsg92618]

I work for a company that has very rigid security guidelines.

I have been given a project to convert a PowerPoint presentation into a web
site that looks exactly like the ppt. this part was easy.

Then I have to provide a button that will convert the whole web site into a
PowerPoint presentation that the user can save on his local machine. The
website is database driven. The approach that I have taken is to dynamically
create the html for each page and save it to a file on the server. Then I
load the page into an IE window and capture to web page as a jpg image. As I
load the html, file into I Explorer the page changes to allow me to create
the next image file. My IT department in their infinite wisdom sees this as
a major security breach.

I need a way turn my html files into an image file without loading it into
IE. Please I need some help. I have looked all over the internet and the
only thing I could find is someone having the same type of issue but no one
has replied to him. I will past my code below.



my work email is (e-mail address removed)

please someone help me



This is a snippet from my constructor method

m_browser = new SHDocVw.WebBrowser();
mshtml.IHTMLDocument2 myieDoc =
(mshtml.IHTMLDocument2)m_browser.Document;
CreateImage(Number_OF_Pages, myieDoc);



The variable Number_OF_Pages is a string array that holds the path to each
html file. The html files has access to all the images and style sheets
needed to render the page the next method is where I create and save the
images



private void CreateImage(string[] PageArray, mshtml.IHTMLDocument2 myDoc)
{



try

string myLocalLink = myDoc.url;




object o = null;

int URLExtraHeight = 0;

if (sbc.ToString().IndexOf("Shell DocObject View", 0) > -1)
{

break;
}
hwnd = GetWindow(hwnd, GW_HWNDNEXT);



}



//Get Screen Height (for bottom up screen drawing)
while ((myPage * screenHeight) < heightsize)
{

myPage, 0);
++myPage;
}
//Rollback the page count by one
--myPage;



int myPageWidth = 0;

g2.DrawImage(screenfrag, brwLeft + URLExtraLeft, brwTop
+ URLExtraHeight);

++myPageWidth;
}



ps I also get these error messages on a random basis



1.Retrieving the COM class factory for component with CLSID
{9BA05972-F6A8-11CF-A442-00A0C90A8F39} failed due to the following error:
8007000e. I get the error when I hit this line of code



shellWindows = new SHDocVw.ShellWindowsClass();



2. OUT OF MEMORY

this one is particulary confusing because when I watch my memory usage
it does not spike
