Thanks Mark...that helped. It was the way we were indicating the path. The
bitmap files still do not render but that's OK.

Tom,
This is clearly not the case. Because you are working with the local html
it needs to know where the image resided based on a correctly formatted
URL. To test this create a new C# winforms app, drop the webbrowser
control and a button on the form. Put a bitmap image in the c directory, I
created on with paint .net and called it file1.bmp. In the button click
event add the following code (make sure to change to the filename of your
image), run and press the button. The image will be displayed successfully
in the browser control.
webBrowser1.DocumentText = "<HTML><HEAD></HEAD><BODY><IMG
SRC='file://c:/file1.bmp' /></BODY></HTML>";
if your images are stored relative to the executing assembly you can
create the path based on that as append it onto your filenames ensuring
that it can file the file correctly.
I hope that this helps,
Mark

The axWebBrowser will not render either the bmp or the jpg files. IE 7
will render the jpg file but not the bmp files. I've even tried
converting the bitmaps to GIF files and it's the same - IE7 OK,
axWebBrowser - Not OK.
Here's more...the HTML being sent to the axWebBrowser is a simple table
(below). Our first take on this was to generate an HTML file saved to
disk and launch IE. This will now work for us as we've learned that if
we change our file type to jpg or gif IE is cool with that. When we
tried to embed this report into the app we found that none of the file
types display. When we run the app and right click on the browser
control and do a view source, what displays in notepad is
<HTML></HTML>...I don't get that...
Here's the code that loads the browser control (axWeb06):
try
{
StringBuilder sbHtml = new StringBuilder();
axWeb06.Navigate("about:blank", ref _empty, ref _empty, ref _empty, ref
_empty);
_doc = axWeb06.Document as IHTMLDocument2;
//wait for document to load
while (_doc.body == null) Application.DoEvents();
strHitChart = "<table border=1><tr><td colspan=2 align=center><B>HIT
CHART " + lbHitTeam.Text + " " + lbHitYear.Text + " " + strDowns +
"Downs</td></tr><tr>";
sbHtml.Append (strHitChart);
// database queries follow to get the rest of the data and do subsequent
sbHtml.Append...
//write the HTML to the document's body
_doc.body.innerHTML = sbHtml.ToString();
}
catch(Exception ex)
{
MessageBox.Show("Error generating HIT Chart - " + ex.Message);
}
This is the html result:
<table border=1><tr><td colspan=2 align=center><B>HIT CHART OHIO 2005

Any idea why IE won't render bitmaps?
Where using a basic img tag:
<img src='formationimages\\formation" + intFormationID + ".jpg'>
Would it work if the extension in the example were changed to ".bmp"?
