Assume you perform login authentication with code below :

bool loginResult = false;

using (DirectoryEntry de = new DirectoryEntry(this.SearchRoot.Path, userDN, password, AuthenticationTypes.Secure))
{
try
{
object x = de.NativeObject;
loginResult = true;
}
catch (COMException comEx)
{
}
return loginResult

}

Just Change the AuthenticationTypes to AuthenticationTypes.Secure will solve the problem. If the AuthenticationTypes is AuthenticationTypes.None then it will able to login with old password. refer this :Windows Server 2003 Service Pack 1 modifies NTLM network authentication behavior

Below id the code: this.txtDate.DataBindings.Add("Text", m_DataRow, "END_DT", true, DataSourceUpdateMode.OnPropertyChanged, null, "dd/MM/yyyy"); when i click on a chkbox event below fired: private void chkbox_CheckedChanged(object sender, EventArgs e) { Boolean isChecked = ((CheckBox)sender).Checked; if (!isChecked) { this.txtDate.Clear() } // Line below will clear the text in text box an also clear the m_DataRow.END_DT. //if (!isChecked) //{ // this.txtDate.Clear() // m_DataRow.SetEND_DTNull() //} } Date that show in the textbox is clear.

And also i found out if user close the form in PrintLayout Mode. I must cancel the report rendering in form close event. this.reportViewer1.CancelRendering(5000); Else the program will hanged forever when user click PrintLayout button. FormReport frm = new FormReport(); this.Cursor = Cursors.WaitCursor; try { frm.ShowReport(sqlStatement + frm2.QueryString + " " + order , reportName); frm.ShowDialog(); } catch (Exception ex) { MessageBox.Show(ex.Message); } finally { //frm.Dispose(); this.Cursor = Cursors.Default; } private void ShowReport(string reportName, ReportsDS reportDS) { if (reportDS.Report.Rows.Count < 1) { MessageBox.Show("No records found. Please import data into system."); this.Close(); } ReportDataSource reportDataSource = new ReportDataSource(); reportDataSource.Name = "ReportsDS_Report"; reportDataSource.Value = reportDS.Report; this.reportViewer1.LocalReport.ReportEmbeddedResource = reportName; this.reportViewer1.LocalReport.DataSources.Add(reportDataSource); this.reportViewer1.RefreshReport(); } private void FormReport_FormClosing(object sender, FormClosingEventArgs e) { try { this.reportViewer1.CancelRendering(5000); } catch (Exception ex) { MessageBox.Show(ex.Message); } }

1.I create a strong typed dataset. 2.I bound the table from the strong Typed dataset to a DataGridView. 3.User Click on a row and press "Select" button. I can just cast the selected row with code below: this.returnedRow = (TypedDS.MasterGroupSearchRow)this.dgvMasterContract.CurrentRow.DataBoundItem; 4.At this moment the this.dgvMasterContract.CurrentRow.DataBoundItem is (TypedDS.MasterGroupSearchRow) But if After Click on the column header .. problem come out ... this.dgvMasterContract.CurrentRow.DataBoundItem will become System.Data.DataRow. So code below will fail .. this.returnedRow = (TypedDS.MasterGroupSearchRow)this.dgvMasterContract.CurrentRow.DataBoundItem; Is there anyway to solve this problem ? or is there anyway to preserve it original typed row ?

Is is possible to create a grid with a checkbox at column header ? like those web form.

I'm using a smart device which run Win CE witn SQL CE 2.0. Would like to know what is the best way to export a table in the device with 50,000 records to a text file. Should i use a SQL SELECT statement like "SELECT * FROM TABLE" into a data set and later loop the DataTable in the DataSet and export write it to a text file ? Or select in it into a DataReader and loop the DataReader? Which one will provide a better performance ? I try to to use method 1 (loop the DataTable in DataSet, but the proble is it take a long time to select all the record into the dataset, and it look like hang over there to the user :zzz:, because i can't update the status and show to the user. However method 2 (loop DataReader) seen like bit better at least i was able to update the status to the user and let user know the program is running. Please kindly advise. Thank in advance.

Thanks for help but an Error Message come out at the same line. The error message is : "Could not bind to the new display member." If i take out the line "this.comboMonth.ValueMember="monthNo" something strange is display in the combo box .. In the combox box it will display "XYZ.Model.Monthlist", where the XYZ.Model is the namespace. this.comboMonth.DataSource = stdData.getMonthList(); this.comboMonth.DisplayMember = "monthDesc"; //If i remark line below some thing strange come out in the combo box //this.comboMonth.ValueMember = "monthNo";

Thanks for help. So i should put the code in a base form class instead of inside the textbox base class right ? Instead of using "this" so what should i use ?

I plan to create a custom textbox class that when user press the enter key it will focus to another control. But i would like to check out that, should i place the GetNextControl method in the textbox class or in the base form class :confused:? I found that code below not working .. X| public class baseTextBox:System.Windows.Forms.TextBox { protected override void OnKeyDown(KeyEventArgs e) { if (e.KeyCode == Keys.Enter) { Control ctrl = this.GetNextControl(this,true); ctrl.Focus(); e.Handled = true; } } } Please advice. Thanks.

Thanks. For clear alll my confuse :doh:

Is is possible to show an MDI child form in Modal Forms ? or any other alternative method to show a child form in Modal Form ?

Thanks. You are right, at the base class the 'object' don't have "Show" method. The "SearchFrom" only instance in the inheritted form but not in the class.

I try to build a Form template in VB.Net so later on i can inherit the form template. in VB.NET i can use Public SearchForm As Object; 'Without instance the real SearchForm Class object 'The real SearchForm will be instance in the inherit form. 'in the init. method SearchForm.Show(); the base class sucessfully Compile. But in C# public object SearchForm 'Without instance the real SearchForm Class object 'The real SearchForm will be instance in the inherit form. 'in the init. method SearchForm.Show() but in C# i can't compile it.. an error message come out : 'object' does not contain a definition for 'Show' :(Please help ... urgent ...
