I am inserting a picture into a database, using the following code.

strFileType = Path.GetExtension(filImage.PostedFile.FileName).ToLower();
switch (strFileType)
{
case ".gif":
strMimeType = "image/gif";
break;
case ".jpg":
case ".jpeg":
case ".jpe":
strMimeType = "image/jpeg";
break;
case ".png":
strMimeType = "image/png";
break;
}
//Store the content length
int iDocLength = filImage.PostedFile.ContentLength;
byte[] bDocBuffer = new byte[iDocLength];
//Get stream object
Stream streamImage;
streamImage = filImage.PostedFile.InputStream;
streamImage.Read(bDocBuffer, 0, iDocLength);
cmPerson.CommandText = "INSERT INTO photos VALUES(@referenceid, @image, @imgtype)";
cmPatient.Parameters.AddWithValue("@referenceid", iPersonID.ToString("000000"));
cmPerson.Parameters.AddWithValue("@image", bDocBuffer);
cmPerson.Parameters.AddWithValue("@imgtype", strMimeType);

Access :: Inserting Into Database In C# Class?

Apr 9, 2010

During an adaption of a book based example application, to use an access database instead of sql server - I have come up with the final issue: It will not insert into the database! I suspect it might be to do with the OrderID, I do have it set to autonumber,but I am not too sure. This is the class that does the inserts, by adding customer information to customer table, order information to order table and ordeitems information to the orderitems table. When submitting this information on the webpage, there is the custom error that an error has occurred in your order due to this code page code behind

bool success = OrderDB.WriteOrder(order);

Session["cart"] = null;

Session["order"] = null;

if (success)

Inserting A Name Into A MySql Database Via Web Application?

Feb 19, 2011

I am having a problem in inserting characters such as a name into a mySql database via an Asp.net application.

If I inserted numbers, the app adds the numbers into the database and I can see them, but the case with names, the name column in the database shows no values (keeps on showing null values) along with the numbers added.

command2 = New MySqlCommand("INSERT INTO customer(Customer_id, Customer_name) VALUES (@Customer_id, @Customer_name)", Connection) // Connection String
command2.Parameters.AddWithValue("@Customer_id", SqlDbType.Int).Value = TextBox1.Text() //assign values
command2.Parameters.AddWithValue("@Customer_name", SqlDbType.VarChar).Value = TextBox2.Text() //assign values

Forms Data Controls :: Validating An Entire Column In Gridview Before Data Is Saved In Database?

Mar 24, 2010

I am using a bound gridview in ASP.NET 2.0. The gridview has the ability to edit/update and insert rows. One of the columns holds a number which represents a percentage. What I cannot figure out is how to ensure that all the rows in the gridview total 100% before being able to send the updates or newly inserted data to the database.

For example say there are 5 rows in the gridview, each row has 20% stored in the column so it adds up to 100% which is fine, the data is updated/inserted in the database. But say each row only had 15% totalling 75%, the user should not be able to send the updated/inserted data to the database until either they add a new row with a percentage of 25 or they edit the other rows for a cumulative total of 100%

I am not familiar with javascript or AJAX

MVC Perform Secured Action - Inserting Row Into Database

Jan 24, 2010

I have an MVC app that uses [Authorize] to protect the private bits. When I select the SignOut() URL it signs me out but if I hit the back button on my browser the it goes to the secure page and even lets me use the form. The action takes place and then it shows that I'm signed out. The problem is that it performs the secured action (inserting a row into my database). Then I can use the back button again and do it all over. Am I missing something important? It seems like it could be a really big security issue.
