I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
I have a VB.net app (which I will turn into a webform soon), my app generates a datatable of values (3 columns and on average about 1000-3000 rows).What is the best way to get this data table into an SQL Server? I can create a table on SQL Server no problem but I've found simply looping through the datatable and doing 1000-3000 insert statements is slow (a few seconds). I'd like to make this as streamlined as possible so was wondering is there is a native way to insert all records in a batch via ADO.net or something.
I have insert a data which is in binary format into sql server database table Column type of table is Image Type. I have to read this column from a XML file,I am able to read but
How to correctly insert image data from XML file to database table using sql server CE and openxml,XML file is written by vb.net DataSet.WriteXml method?image data is stored in database table is :
0x89504E47.my XML file Content after written by WriteXml method is : <?xml version="1.0" standalone="yes"?> <Data> <Table> <image>iVBORw0KGgoAAAANSUhEUgAAAcIAAAGuCAYAAAADLg..</image> </Table> </Data>
but after inserting with openrowset and openxml using stored procedure to another database table its value changes to this :0x2F0039006A002F00340041004100510.and is not the first value and raises an error in vb.net for opening image from database.
I have a Windows application form. Directly on the form I have a lable ("Customer Names"), a ComboBox (pulling actually names from a database) , and a Buton to add a customer to the database if i choose. Additionally I have ControlTab(3 tabs) that has "fields" and its own Buttons to insert data into a different table. The first 2 tabs have textBoxes, which are completely functional, but the 3rd tab has a "DataGridView"
Inside my application, I need to insert data from two sources: table and form textbox. So I tried to use the code below, but the message box is displaying an error. (I am using vb.net)
Error: While inserting record on table ..Syntax error (missing operator) in query
Code: Dim con As New OleDbConnection Dim cmd As New OleDbCommand Try con.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:UsersDellXPSDesktopmDB.accdb" [Code] .....
I am doing a project on sending mass email. My codes should be able to read contacts/email from the SQL Server 2005 database and send mass email with attachments.Below are my codes for sending email. My windows application limitation is that it can only send email from a valid email address to a valid address one at a time with the help of a relay server. Also, it doesn't allow the user to attach attachments and could not read from the sql server database.[code]

I use a simple master-detail form using Visual basic 2005 express edition and ms sql server 2005 express edition, as well.
The master table is dept (deptno int, dname nvarchar(50)) .
The deail table is emp (empno int, deptno int, ename nvarchar(50)).
The primary key for the dept table is deptno and for the emp table is empno.
There is also a foreign key (deptno on emp table).
I created a new project, connected to a db (called test.mdf) and created a data source consisting the two of the above reffered tables.
I dragged and dropped these tables on the form and i noticed the following:
1)When the form opens... the system queries the database and displays the data on each block on the form.
2)I insert and/or update a record on the master table (dept) and everything goes well...
3)I try to insert and/or update a record on the detail table (emp) and nothing is changed on the detail table - without any error.
4)When i try to insert and/or update a record on the detail table (emp) which violates the primary key constraint or foreign key the system complaints...(as expected).
I have a form program that runs long, and for kicks I was wondering if I could out put some data to a "real console" -not the Console useing the Output debugger.
I'm trying to insert a row into a SQL Server table.
Using this... cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (@firstname, @lastname)" cmd.Parameters.AddWithValue("@firstname", "bob") cmd.Parameters.AddWithValue("@lastname", "jones") cmd.ExecuteNonQuery()
I get an error saying: ERROR [42000] [Microsoft][ODBC SQL Server Driver][SQL Server]Must declare the scalar variable "@firstname".
But if I use this... cmd.CommandText = "INSERT INTO MyTable (firstname, lastname) VALUES (?, ?)" cmd.Parameters.AddWithValue("@firstname", "bob") cmd.Parameters.AddWithValue("@lastname", "jones") cmd.ExecuteNonQuery() ...it works fine. What do I need to do to make the first example work? I don't understand what the error message is telling me. How do I declare a "scalar variable"?
I have two windows vb.net form. I got a text file. I am trying to encrypt some data and save it to a text file with the 1st windows vb.net 2005 form. Now with the second one am trying to decrypt the data and retrieve it here.
I want to implement a button that sends values typed in textboxes of gui(vb.net i'm using visual basic 2008) into a sql server table called Noms.
Example:
2 textboxes id=1 nom = michael
Press button send the the 2 values into the 2 columns (id and name) of Noms table Then I enter in textbox(gui vb.net) id=2 and nom=mike So the output in my Noms table of sql server should be:
Id Nom 1 michael 2 mike
Here's the code implemented in button to send the values into the specified table:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click 'Public Class account 'myconnection=conexiune 'comandasql=mycommand
I want to add or update columns using alter table if i am adding a new column i want show rror. I am using the code belowalter table Personal_Details alter columns DOB datetimef i uncheck the NULL to not NULL then it will shows column does not allow nulls; update fails;i want to insert the fields in between columns not at end.
I want to insert data to a table in SQL DB.I have a combo box with the values "5" and "6". When you click one or the other in the combo box i want these values to be inserted in a database( MS SQL Server 2008).I also have some textboxes which are bind correnctly and have no problem. The problem is with the bindings(i guess) of the combo box. I get sql exception.
Here is a snippet.
Private Sub BindFields() txtSurname.DataBindings.Add("Text", ObjDataView, "surname") txtName.DataBindings.Add("Text", ObjDataView, "name")
In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment
Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1).
How do i have to change my database setup, that the original QuestionNumbers are copied into the database?
and this is the parameter that I am calling.For some reason this method does not work. I get an error saying that it expects a parameter @DELAY_CAUSE_1 which is not supplied. I check my procedure code and everything is matching up. Am I missing something here? Sorry that I haven't provided more into but the short question is how do I add the value of a combobox that has been selected? I just want to enter the number of the value selected into the table. But the combobox list will display the string.
and what I'd like to do is when users edit something on this form that they post the changes to a table called exceptionsedit which is not part of that dataset. What I don't know how to do is to how to insert those edits to the exceptionsedit table.
I would like to insert the value of AttendanceID(PrimaryKey, Identity), ClassID(Value From combobox1), StudentID(from a variable).
Private Sub RegisterAttendance(ByVal sender As System.Object, ByVal e As System.EventArgs) Const ConnectionString As String = "Initial Catalog='FingerPrint';Integrated Security=True;Data Source=FORC3-BCSQLEXPRESS"
i have a app in visual basic mobile 2008, so i finish but now i need to tranfer the data generate in the in the app mobile to data base in sql server 2008.
I have an application that collects digital signatures, and saves them as a bitmap to a specified directory. After the code saves the bitmap, I use a SQLDataAdapter to insert the path to the bitmap into a text field. All the code works on my computer, but on customer computers it does not. I do not get an error msg, but the string value of the path is not inserted. All security works because they can write any other records to the same database. [Code]
