what I want to happen is when I click another button called "Apply to all" I want to Update all the daystatus to "Legal Holiday" of the filtered records..I know how to update one by one using simple update..but I need to do the multiple update..
I tried to make a code but it was updating all the records not the filtered only here's my code:
try {
OleDbCommand command = new OleDbCommand();
connection.Open();
command.Connection = connection;
string query = "SELECT EID From EmployeeTable";
command.CommandText = query;
String a = "Legal Holiday";
I'm trying to get some more user friendly things in my program done. Now I'm trying to filter by typing in a text box and it filters to what you are typing and shows the entire row.
I have the following code. I am able to call data from my database and print the result onto datagridview. However, if I happen to edit some data through datagridview, I would like it to save the changes by clicking a save button. I do not know how to connect callDBButton_Click and saveButton_Click...I know how to update the changes if I just put adapter.Update(dataTable); at the end of the callDBButton_Click method...but I want to it only save changes when I CLICK the "Save" Button.

a user can edit quantity ie productID 1 has quantity 10, and ProductID 2 has quantity 3, it should update once clicked update button. however i must highlight both rows to do it so if i leave the selected cell on product id 3 it will upate only that row. is there a way to update the rows that have been changed when not highlighted.
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++) { int selectedrowindex = dataGridView1.SelectedCells[i].RowIndex; DataGridViewRow selectedRow = dataGridView1.Rows[selectedrowindex]; string a = Convert.ToString(selectedRow.Cells["Quantity"].Value); string b = Convert.ToString(selectedRow.Cells["ProductID"].Value); //update to database..... }
I have a program in C#.net. There is a datagridview which shows all the details of the student. Then I add a column to update another column using the value I entered. Means I want to add roll no to student details table while running. I want the code to update it. Is it possible?
I'm trying to add a function now that lets the user open 1 or more files and import them to the database and dataGridView. Now the way it is now (should) work. But when it has finished with FILE1, it won't add FILE2 as it then gives me an error that the Column Date Already exists.

I am starting a project in a few weeks that needs to be able to prevent an executable from running until it has been checked for various criteria (think of it as a DIY anti virus).
My main idea is to build a file filter driver in C to hook into file system reads and writes and prevent executables that I don't like from executing off the disk.
I have a gridview, im using its 'datasource dropdownlist' to populate it, i have the SQL statement
SELECT Orders.ID, OrderDetails.ProductId, OrderDetails.ProductName, OrderDetails.Quantity, OrderDetails.Price, OrderDetails.Total FROM (OrderDetails INNER JOIN Orders ON OrderDetails.ID = Orders.ID) WHERE (Orders.CustomerId = ?)
where the '?' is parameters source = QueryString, and QueryStringField= email
i have a session that is the customerEmailId, so
string CustomerEmailID = (string)Session["email"]; Response.Redirect("MyAccount.aspx?email=" + CustomerEmailID);//i have tested it and customerEmailid is test however nothing loads in the GridView
I have a C# WPF program that takes a SQL query and populates a column from an Oracle database into a listbox on the form. I would like to be able to compare all items populated in the listbox, and run a SQL query for each item, populating those values into a different listbox.
So far, I have this code:
string sql2 = "select unique apps.fnd_application_all_view.application_name, fnd_responsibility_vl.responsibility_name, fnd_form_functions_tl.user_function_name, fnd_form_functions.function_name, fnd_form_functions_tl.description, fnd_form_functions.type FROM fnd_compiled_menu_functions, fnd_form_functions, fnd_form_functions_tl, fnd_responsibility, fnd responsibility_vl, apps.fnd_application_all_view WHERE
[code]....
I would like to be able to basically take the "Responsibility_Name" value from the first listbox (lstResponsibilities), which is already populated, and use those values to in the "sql2" query to find the "Function_Name" and populate "Function_Name" in the second listbox (lstFunctions).
So I've been working on this for awhile and FINALLY got it to work. This is my code
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text;
[Code] ....
As you can see I will have the Name and total right next to eachother.. Problem is I dont want to make a million MySQLCommands for each ID.. Is there a Way I can list all data in each label?
For instance the Select from Text will show all the text from each different ID and the Select from STOCK-USED as total will show all the total for each ID
Instead of having to list them individually.
Even if I leave it to this
"Select text FROM `parts`";
It selects the 2nd ID in my database and displays its text.. Forgets about the first one completely ...
I have table called leavetable where in i have the fields eid, lfrom,lto, reason,status an employee will insert these fields in the leave form except status, status will be updated by admin but there is no unique field in the table so when the admin updates the status as cancel for an id emp001 so whereever this id is present in the table its getting updated to cancel even though it is approved previously.. How to avoid this duplication ?
SqlConnection con = new SqlConnection(Connectionstring); con.Open(); string sql = "update leavetable set status = '"+status+"' where eid = '"+textBox1.Text+"' and noofdays = '"+textBox5.Text+"'";
I have WCF web service which contains methods for communicating with database (ms sql). For a long time I was using pure sql statements, that aren't secure. It is time to move to parameterized queries. I'm using code-engine.com source code for query builder. Example of it is here: SelectQueryBuilder: Building complex and flexible SQL queries/commands from C# . Which works OK and I have no problems when is used inside of web service.
The problem: I also have asp.net web site which uses this webservice and the main problem is, how to build queries on client side and sent them to web service? I can build query on client side and send dbCommand.commandtext but I then I don't know how to send parameters list to webservice, because it isn't serialized.
This would be used as "universal" method for sql statements. I have others method like getUser(),getUsers(),getPages() but I really need this kind of methods to pass query to it.
I am displaying data from an Excel Spreadsheet through an ASP.net web form using C#. I would like to run an SQL query on the data, but am having trouble figuring out how to use a string in my query.
Here is the code I am running in my .aspx.cs file. I am also using a .aspx to display the data in a GridView.
Ideally, I would like to add a WHERE clause to my string (string sSQL = "SELECT * FROM [Sheet1$A1:D14]"/> in order to query the current month and display the row of said month from the Excel Spreadsheet.
I have attempted to use a DataAdapter to insert the string into the query, but could not figure out how to conform my code to work with it.
I am trying to query an Informix database using a List<T> collection's elements as variables. I can build the list and connect to the database, but I am unsure how to iterate through the list and query the database for each item in the collection.
My list is of type string, and contains Order Numbers. I want to query item information for each order number in the list.

I am trying to query dates between two textbox values converted to datetime in C#. The dates are returning in the correct datetime and no conversion problem exists there.
However when I run the below LINQ to SQL query in C# it returns no enumerable results. But if I take the below code:
DbCommand dc = dbHistoryContext.GetCommand(qryRes); Console.WriteLine(dc.CommandText);
and get the results as a string of text and cut and paste that into the SQL Server Management studio and execute it - then it works. What do I need to do to search between two dates so that it properly works. The field is of format Date in SQL Server if that matters and the fields being used to pass the information to it are DateTime. The compiler doesn't show any errors but it just doesn't return results.
var qryRes = (from res in dbHistoryContext.tblR where res.updateddate >= dtDateFrom.Date && res.updateddate <= dtDateTo.Date select res);
