    <p>The conversion of a varchar data type to a datetime data type resulted in an out-of-range value error</p> <p>I'm trying to enter data into my table using a form, the date formats in both the form validation and the sql server are both dd/mm/yy, however when i try to submit data from the form with a day higher than 12 (e.g. 13/12/2012) it throws an exception whose cause is "The conversion of a varchar data type to a datetime data type resulted in an out-of-range value error", and if i try to enter data into the form in a mm/dd/yy format it states "wrong date format" which is suppose means that the dd/mm/yy format is the correct format</p> <p>here's the code for my form below:</p> <pre><code> private void btnAddProject_Click(object sender, EventArgs e) { DateTime startDate; DateTime endDate; if (txtProjectName.Text == "") //client side validation { MessageBox.Show("Enter Project Name"); return; } try { startDate = DateTime.Parse(txtProjectStart.Text); endDate = DateTime.Parse(txtProjectEnd.Text); } catch (Exception) { MessageBox.Show("Wrong Date Format"); return; } fa.CreateProject(txtProjectName.Text, startDate, endDate, (int)cbCustomers.SelectedValue, ptsUser.Id); txtProjectName.Text = ""; txtProjectStart.Text = ""; txtProjectEnd.Text = ""; cbCustomers.SelectedIndex = 0; MessageBox.Show("Project Created"); adminControl.SelectTab(2); }// end btnAddProject </code></pre> <p>And this is the code in my DAO:</p> <pre><code>public void CreateProject(string name, DateTime startDate, DateTime endDate, int customerId, int administratorId) { string sql; SqlConnection cn; SqlCommand cmd; Guid projectId = Guid.NewGuid(); sql = "INSERT INTO Project (ProjectId, Name, ExpectedStartDate, ExpectedEndDate, CustomerId, AdministratorId)"; sql += String.Format("VALUES('{0}', '{1}', '{2}', '{3}', {4}, {5})", projectId, name, startDate, endDate, customerId, administratorId); cn = new SqlConnection(Properties.Settings.Default.WM75ConnectionString); cmd = new SqlCommand(sql, cn); try { cn.Open(); cmd.ExecuteNonQuery(); } catch (SqlException ex) { throw new Exception("Error Creating Project", ex); } finally { cn.Close(); } }//end CreateProject Method </code></pre> <p>This is my code for my facade:</p> <pre><code>public void CreateProject(string name, DateTime startDate, DateTime endDate, int customerId, int administratorId) { dao.CreateProject(name, startDate, endDate, customerId, administratorId); }//end CreateProject </code></pre>
