what you mean by load file? if you mean you want to load the file in browser without creating on disk, well it can be done but with a trick like this: Read the file from db(access) into string variable and then write that string variable into a temp html file and execute that htmlfile in browser, and after loading the file into browswer (may be 1 or 2 second delay be required) delete that temp html file let see if this works :~ --------------------------- http://www.idlsol.com

I did it before, it works , but this solution ,for network with different permission may cause some problem. I want load browser directly with htmltext, without create and save file.

well then you need to use memory stream as the source for the browser to read the html contents, but im not sure about this that either browser will read from this memory stream or not what else can be done is you embed the browser control (if IE) in your application and then try to send html text to that browser control programmically --------------------------- http://www.idlsol.com

I read it, thanks, but there is a problem for using memory stream as a solution : how i can bind a memory stream file to a web browser??!!! :confused:

If you want to load HTML file in a webbrowser control, Its the straight forward way to set the property value of DocumentText of the Webbrowser with the HTML string. Example, If your Webbrowser control has instance name, webBrowserControlMyBrowser then string htmlString = " Hello World "; webBrowserControlMyBrowser.DocumentText = htmlString; In this way, You dont need to create a file, save and delete etc, moreover, you dont even need to wait for couple of seconds to load. Its the DIRECT way. Emran

Thanks. but im working with VisualStudio.net 2003, and this property "DocumentText" is not valid for web browser control!!! :confused: Salmani

        {
            System.IO.MemoryStream st = new System.IO.MemoryStream ();
            string sampleHtml = "Hello world! ";
            UTF8Encoding uniEncoding = new UTF8Encoding();

            // Create the data to write to the stream.
            byte[] firstString = uniEncoding.GetBytes(
                sampleHtml);

            webBrowser1.DocumentStream = st;
            st.Write(firstString, 0, firstString.Length);
            st.Flush();
            st.Position = 0;
