| Pozdrav svima !!!! Za cuvanje podataka u programu koristim MySQL bazu. Za vezu sa tom bazom MySQLConnector v 5.2.1.0. Problem postoji sa ucitavanjem podataka iz baze, tacnije red Adapter.Fill pravi problem. Ako se kod za ucitavanje nalazi u npr. dogadjaju Load forme podaci se ucitavaju bey problema, ali ako se kod za ucitavanje prebaci u klasu, u proceduri klase koja ucitava podatke na redu Adapter.Fill VBENT javlja sledecu gresku: System.ArgumentNullException was unhandled Message="Key cannot be null. Parameter name: key" ParamName="key" Source="mscorlib" StackTrace: at System.Collections.Hashtable.get_Item(Object key) at MySql.Data.MySqlClient.MySqlPoolManager.GetPool(MySqlConnectionStringBuilder settings) at MySql.Data.MySqlClient.MySqlConnection.Open() at System.Data.Common.DbDataAdapter.QuietOpen(IDbConnection connection, ConnectionState& originalState) at System.Data.Common.DbDataAdapter.FillInternal(DataSet dataset, DataTable[] datatables, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable) at MSG_NET_1.clsBaza.UcitavanjePodataka(String SQLUpit) in D:\Projekti\VB NET_2008\MSG_NET_1\MSG_NET_1\clsBaza.vb:line 27 at MSG_NET_1.Form1.Form1_Load(Object sender, EventArgs e) in D:\Projekti\VB NET_2008\MSG_NET_1\MSG_NET_1\Form1.vb:line 9 at System.EventHandler.Invoke(Object sender, EventArgs e) at System.Windows.Forms.Form.OnLoad(EventArgs e) at System.Windows.Forms.Form.OnCreateControl() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) at System.Windows.Forms.SafeNativeMethods.ShowWindow(HandleRef hWnd, Int32 nCmdShow) at System.Windows.Forms.Control.SetVisibleCore(Boolean value) at System.Windows.Forms.Form.SetVisibleCore(Boolean value) at System.Windows.Forms.Control.set_Visible(Boolean value) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(ApplicationContext context) at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnRun() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.DoApplicationModel() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine) at MSG_NET_1.My.MyApplication.Main(String[] Args) in 17d14f5c-a337-4978-8281-53493378c1071.vb:line 81 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException: U CEMU JE PROBLEM ???
