    <p>I have a C# asp.net web page which reads PDF file from Mysql database (which stores as longblob format) and open it. It works in my Localhost; the page reads the file from database and open with acrobat reader but it doesn't work in the testing server after i deploy the page. The acrobat reader doesn't open and i don't see acroRd32.exe in the taskmgr manager. I feel it is permission issue because i use process.start() which may not allow in the server but i dont see error messages. If there are permissions needs to be done in server; can anyone kindly points me the direction?</p> <p>Thank You.</p> <h2>Here are my code:</h2> <pre><code>MySqlDataReader Reader = null; connection.Open(); MySqlCommand command = new MySqlCommand("Select Image, File_Type, File_Name from table where ImageID = " + ImageID, connection); Reader = command.ExecuteReader(); if (Reader.Read()) { byte[] buffer = (byte[])Reader["Image"]; System.IO.MemoryStream stream1 = new System.IO.MemoryStream(buffer, true); stream1.Write(buffer, 0, buffer.Length); String fileName = Reader["File_Name"].ToString(); String dirName = "C:\\thefolder\\"; if (!Directory.Exists(dirName)) { // if not then create Directory.CreateDirectory(dirName); } if (File.Exists(dirName+fileName)) File.Delete(dirName + fileName); Directory.CreateDirectory(Path.GetDirectoryName(Reader["File_Name"].ToString())); using (Stream file = File.Create(dirName + fileName)) { file.Write(buffer, 0, buffer.Length); } Process process = new Process(); process.StartInfo.FileName = "AcroRd32.exe"; process.Start(); } </code></pre> <p>Thanks for your help, i am able to send pdf content via response. Here is the code</p> <pre><code>//Process process = new Process(); //process.StartInfo.FileName = "AcroRd32.exe"; //process.Start(); Response.ClearHeaders(); Response.ContentType = "application/pdf"; Response.Clear(); Response.AppendHeader("Content-Disposition", "attachment"); Response.TransmitFile(dirName + fileName); Response.End(); </code></pre>

    3. COno error, The web page runs and acroRd32.exe doesnt' run. All i want is user is able to see the PDF file which stores in the database when they click the web page. If they need to save the file in the their own machine first and open it. that is fine too.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
