Hi,
I am using visual studio 2010 .I have created web application using Asp.net C# .I need to Import Excel Data into Sqltable called assessment Table. Assessment Table has Following columns
ID Date BestPlusScore BestLitScore BestPlusLevel BestLitLevel StudentId
My Excel Has following Columns :
| Date | BestPlusScore | BestLitScore | BestPlusLevel | BestLitLevel | Student Name |
| 8/12/2014 | 88 | 0 | Agaiby Esam | ||
| 3/29/2014 | 204 | 0 | Amien Mervaf |
Instead of studentName need to convert StudentId from student table .StudentId should be saved in Assessment table.
Can Any one tell me how to convert studentname as student id ? Please Reply as soon as possible :)
I added the correct MIME but still getting the warning.
Response.AppendHeader("content-disposition", "attachment;filename=ExportedExcel.xls");
Response.Charset = "";
Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.ContentType = "application/vnd.ms-excel";
Is there anymore things I need to do pro grammatically to suppress this?
Thank You

hi guys, i have installed MySQL ODBC Driver 3.51 & 5.1 in my pc.
I got the following error if my connection as below:
Dim ConnStr As String = "DRIVER={MySQL ODBC 5.1 Driver};SERVER=localhost;DATABASE=db_testing;UID=user_testing;PASSWORD=12345;OPTION=3;"
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
* but it's working fine if i change ODBC 5.1 Driver to ODBC 3.51
Please advice. TQ
Forgive me if this is in the wrong place but I figure I would ask here anyway. I am using OleDB to read records from Excel. The crazy thing is it was working properly for the longest. Now all of a sudden, it takes my records and duplicates them. To rule out code related issues, I tried a test on an excel with only one record. That one was fine. So I figured after my reboot the problem was resolved. It is not. I simply do not get what the problem is because it does not always do this. It is at random.

We have built a project that runs a SQLite db for the backend stuff. Something we noticed while finishing up the project was issues with Boolean values.
In one table we have 1 column that is set to Boolean as the type, our inserts are working and you can see when a record is inserted that the appropriate data is being inserted and stored. But when viewing the information on the page its always showing false. Now by accident we found out that if we go into the db and simply set and reset the Boolean value, when we revisit the page it shows correct.
So even though our inserts are working, there is a manual step to have it reflect correctly.
Can anyone offer suggestions on how to resolve this or things to try or check to see if we can fix this..
Hi,
I am trying to build an sql command that selects multiple key words from one field in an Access Database then orders the results by the date they were added
currently my sql statement is as follows;
SelectCommand="SELECT [ID], [PartNo], [Description], [Date] FROM [StockItems] WHERE (([Category] = "TVs" AND "SoundEquipment") AND ([ShowOnSite] = true)) ORDER BY [Date] DESC"></asp:SqlDataSource>
However currently the command is returning the first category listed (in the case of the example TVs are returned first, if i move Sound equipment to be the first category listed then the sound equipment results are listed first), I need it so that the results are mixed based on the date which they were added.
How to fix this?
Thanks
I have a webservice that has one main function. This function makes several insert/update/deletes as it process.
Each of those insert/update/deletes are in there on function in their respective class's.
In each of those functions I
I have been asked to make this all transaction based, so that after it performs all say 5 inserts/updates/deletes (depending on what was sent to the service) Then I can commit or rollback at the very end of the main function.
I have found examples on how to do it on each Insert/update/delete. The goal is to make sure they are all successful and then commit, or if any fail, rollback.
I'm experienced in building web sites using VS 2013 but never used mySQL until now. I can't seem to connect to the mySql database I created. Here is my code:
string MyConString = "SERVER=localhost;" +
"DATABASE=XXXXXDB;" +
"UID=bobh;" +
"PASSWORD=ppppppppp;";
MySqlConnection connection = new MySqlConnection(MyConString);
MySqlCommand command = connection.CreateCommand();
MySqlDataReader Reader;
command.CommandText = "select * from Products";
connection.Open();
Reader = command.ExecuteReader();
while (Reader.Read())
{
string thisrow = "";
for (int i = 0; i < Reader.FieldCount; i++)
thisrow += Reader.GetValue(i).ToString() + ",";
//gvProducts.Rows.Add(thisrow);
}
connection.Close();
On the connection.Open() line I get this error:
[MySqlException (0x80004005): Authentication to host 'localhost' for user 'bobh' using method 'mysql_native_password' failed with message: Access denied for user 'bobh'@'localhost' (using password: YES)] My
What am I doing wrong?

pass3img.ImageUrl = path;
//this gets admin1passport
Stream fs3 = FileUpload6.PostedFile.InputStream;
BinaryReader br3 = new BinaryReader(fs3);
Byte[] bytes3 = br3.ReadBytes((Int32)fs3.Length);
try
{
MySqlConnection conn = new MySqlConnection(connection);
MySqlCommand ins = new MySqlCommand("update tables.admintable set Passport = @img where Name = '" + newname.Text + "'", conn);
MySqlDataReader read;
conn.Open();
ins.Parameters.Add("@img", MySqlDbType.Binary).Value = bytes3;
read = ins.ExecuteReader();
conn.Close();
Label84.ForeColor = System.Drawing.Color.Green;
Label84.Text = "Successful Upload";
}
catch (MySqlException)

read = select.ExecuteReader();
while (read.Read())
{
byte[] passportImage1 = (byte[])(read["Passport"]);
if (adminListBox.SelectedIndex.Equals(0))
{
if (passportImage1 == null)
{
adminImage.ImageUrl = null;
}
else
{
MemoryStream ms = new MemoryStream(passportImage1); // this holds the image gotten from the database
string base64string = Convert.ToBase64String(passportImage1, 0, passportImage1.Length);
adminImage.ImageUrl = "data:image/png;base64," + base64string;
}
}
}
read.Close();
conn.Close();
catch (MySqlException)
{
Label84.ForeColor = System.Drawing.Color.Red;
Label84.Text = "Failed Upload, Please Try Agin";
}
catch (Exception)
