My form has a picturebox and Open and Save buttons. I'm trying to insert the picture from my picturebox into database using the code below. Picture opens as it should and shows up in the picturebox, but pressing the save button isn't working. It says either cn. Open is an error or the executenonquery.

Simply you can create a Global variable of Datatable to use it as source of Data and you can use it anywhere in your Forms
This is the GLobal Class
//make sure to import this System.Data
using System.Data;
class Global
{
private static DataTable source;
public static DataTable Source
{
get
{
// Reads are usually simple
return source;
}
set
{
// You can add logic here for race conditions,
// or other measurements
source = value;
}
}
}
In your first form
string connectString = "datasource=xxxx;port=3306;username=xxxx;password=;database=xxxxx;";
MySqlConnection conn;
MySqlCommand comm;
MySqlDataReader read;
MySqlDataAdapter adapter;
Global mySource;
void getData() {
string query = "Select * from tableName";
conn = new MySqlConnection(connectString);
conn.Open();
comm = new MySqlCommand(query, conn);
adapter = new MySqlDataAdapter(query, conn);
DataSet ds = new DataSet();
adapter.Fill(ds);
//setting up
Global.Source = ds.Tables[0];
dataGridView1.DataSource = ds.Tables[0];
conn.Close();
}
In you second Form
public Form2()
{
InitializeComponent();
dataGridView1.DataSource = Global.Source;
}
Simply you can create static method in the class of form3 and accept one argument from DataGridView type and call this method from form1 and pass dg1 after filling it with rows then you can access it now from this static method...
private void dgv1_CellClick(object sender, DataGridViewCellEventArgs e) {
Form3 Form3 = new Form3();
Form3.staticMethodToPassDGVBetweenTwoForms(dgv1);
Form3.ShowDialog();
}
namespace erpmam {
public partial class Form3 : Form {
public Form3() {
initializeComponent();
}
public static void staticMethodToPassDGVBetweenTwoForms(DataGridView dgv1){
//do anything with dg1 now
}
}
I have a program which user can input some data and the data will be storaged into a database (i use Ms Access). But, the program also can do some search of existing data from database. User can input a keyword from textbox and the program will show the data from database.
Like this:
User will input a keyword or a text to "Kd. Dosen" textbox then it will show the data from database contains that keyword. Here is the database:

You have to add textbook_change option to double click textbook which you want to write text and filter.
private void txtCariKodu_TextChanged(object sender, EventArgs e)
{
FilterByName();
}
your method is contains a variable which is your db query like (SELECT * FROM YOUTRABLE WHERE NAME LIKE % ).
and now you can show filtered values on your Datagridview.
public void FilterByName()
{
var result = YOURSQLQUERY.ToList();
dataGridView1.DataSource = result;
}
I have been staring at this UPDATE statement for a long while and are unsure why my table isn't changing. When I press the button no error appears but my table doesn't not get updated either, I have checked that all of my variables have values on debug and they do.
I'd appreciate any help anyone can give me!
This is the code that contains the statement I need help with:
private void button1_Click(object sender, EventArgs e)
{
string studentanswertext = textBox1.Text;
string connectionString = ConfigurationManager.ConnectionStrings["myconnectionstring"].ConnectionString;
string y = GlobalVariableClass.Signedinteacher;
Convert.ToInt32(y);
MessageBox.Show(y);
MessageBox.Show(Convert.ToString(CurrentQuestionID));
MessageBox.Show(studentanswertext);
SqlConnection connect = new SqlConnection(connectionString);
connect.Open();
SqlCommand command20 = new SqlCommand(#"UPDATE QuestionStudentAssociation SET ([StudentAnswer]=#StudentAnswertext) WHERE ([QuestionID]=#CurrentQID AND [StudentID]=#SignedinStudent )", connect);
command20.Parameters.AddWithValue("#StudentAnswertext", studentanswertext);
command20.Parameters.AddWithValue("#CurrentQID", CurrentQuestionID);
command20.Parameters.AddWithValue("#SignedinStudent", y);
command20.BeginExecuteNonQuery();
connect.Close();
}
This is the whole code for my form if anyone wanted to look at it just in case that is affecting the button even handler:
namespace ComputingA2_Official_Project
{
public partial class CurrentlySetTestForm : Form

connect.Open();
SqlCommand command18 = new SqlCommand("SELECT MIN([QuestionID]) AS QuestionID FROM QuestionStudentAssociation WHERE ( [StudentID]=#Signedinstudent AND [StudentAnswer] IS NULL )", connect);

var reader = command18.ExecuteReader();
while (reader.Read())
{
CurrentQuestionID = Convert.ToInt32(reader[0]);
SqlCommand command19 = new SqlCommand("SELECT ([Question Space]) FROM Questions WHERE ([QuestionID]=#CurrentQID)", connect);
command19.Parameters.AddWithValue("#CurrentQID", CurrentQuestionID);
using (SqlDataReader reader2 = command19.ExecuteReader())
{
while (reader2.Read())
{
QuestionSpace = Convert.ToString(reader2[0]);
label1.Text = QuestionSpace;
}
}
}
connect.Close();
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
}
private void button1_Click(object sender, EventArgs e)
{
string studentanswertext = textBox1.Text;
string connectionString = ConfigurationManager.ConnectionStrings["myconnectionstring"].ConnectionString;
string y = GlobalVariableClass.Signedinteacher;
Convert.ToInt32(y);
MessageBox.Show(y);
MessageBox.Show(Convert.ToString(CurrentQuestionID));
MessageBox.Show(studentanswertext);
SqlConnection connect = new SqlConnection(connectionString);
connect.Open();
SqlCommand command20 = new SqlCommand(#"UPDATE QuestionStudentAssociation SET ([StudentAnswer]=#StudentAnswertext) WHERE ([QuestionID]=#CurrentQID AND [StudentID]=#SignedinStudent )", connect);
command20.Parameters.AddWithValue("#StudentAnswertext", studentanswertext);
command20.Parameters.AddWithValue("#CurrentQID", CurrentQuestionID);
command20.Parameters.AddWithValue("#SignedinStudent", y);
command20.BeginExecuteNonQuery();
connect.Close();
}
private void timer1_Tick(object sender, EventArgs e)
{
}
}
}
I believe the issue is that you are executing the command asynchronously (BeginExecuteNonQuery), but never calling EndExecuteNonQuery to commit it. I also suspect you could just call it synchronously like this:
command20.ExecuteNonQuery();
Hi I have used the code below to save images to my database,
but now I want to know how I can get the picture from the database to a PictureBox
can you please help me.
private void button1_Click(object sender, EventArgs e)

string i = ofdFoto.FileName.ToString();
pbxFoto.ImageLocation = i;
}
private void button2_Click(object sender, EventArgs e)
{
dbConn.Open();
string querys = "INSERT INTO Fruits (Name, Picture) VALUES ('" + txtName.Text + "','" + ImageToByte(pbxFoto.Image) + "')";
OleDbCommand cd = new OleDbCommand(querys, dbConn);
cd.ExecuteNonQuery();
dbConn.Close();
MessageBox.Show("Picture saved", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
public static byte[] ImageToByte(Image img)
{
ImageConverter converter = new ImageConverter();
return (byte[])converter.ConvertTo(img, typeof(byte[]));

{
PictureBox p =new PictureBox();
p.ImageLocation = ofdFoto.FileName.ToString();

See if this helps you!!
Try this code:

return img;
}
}
and set to PictureBox.Image property:
pictureBox1.Image = BytesToBitmap(byteArray);
I have a problem regarding with add an image URL within a database.I'm using fileupload method within formview in ASP.Net.And I have a table called duyurular

However,I want to record it within database as well.when to add within database another those infos,there are no the image URL.

thanks in advance for all comments you can share.
I suggest that you just upload the image name without specifying the full URL, and you can save the image base path in the web.config like '<add key="ImagesBasePath" value="/img" />' so you can change the path were you have your images and you can control the view of this image by concatenating the Image name to ConfigurationManager.AppSettings["ImagesBasePath"] so this will be better.
You have to use Formview ItemInserting Event, where you can pass in the built URL.
protected void frmAsset_ItemInserting(object sender, FormViewInsertEventArgs e)
{
if (dosya.HasFile)
{
dosya.SaveAs(Server.MapPath("~/img/") + dosya.FileName);
e.NewValues["URL"] = "img/" + dosya.FileName;
}
}
