honeyashu

Hi all I am facing a problem in my application some times it appears to user that system/ application get hanged and he is unable to do ANY THING, the only option left to him that to kill the application using Task Manager. I found the reason that actually my message box is went to back of the current window due to which focus gets lost from the front. I searched on the net and found that in my application overriding of a windows method cause such problem this method is used to draw and display a timer/click on the MDI form rest i dont know about the functionality. I am attaching the code if any body can help please reply as it's really confusing for me and i am not getting any solution for the same

protected override void WndProc(ref System.Windows.Forms.Message m)
{
try
{
base.WndProc(ref m);
switch (m.Msg)
{
case (int)WM_TIMER:
// If Autolock feature gets started
if (PreferencesController.IsAutoLockStart)
{ //_stastAL will be true only for the Form load and if in Preferenes ,AutoLock is assigned as true.
if (PreferencesController.IsSetAutoLock)
{ //Starts the hooking of Keyboard and mouse hooks
actHook.Start();
//specifies the end time
PreferencesController.EndTimeAutoLock = DateTime.Now.AddMinutes(PreferencesController.LockWorkStationTimeInMinute);
PreferencesController.IsSetAutoLock = false;
}
AutoLockWS();
}
if (PreferencesController.IsShowDateTime)
Main_OnNcPaint(ref m);
//To Run Macro TODO: Take it from config file

                         if (DateTime.Now.ToLocalTime().ToShortTimeString().Equals(
                             ConfigurationService.GetExcelMacroExecutionTime()))
                            ExcelFile.RunMacro();  
                    break;
                case (int)WM\_NCPAINT:
                    if (PreferencesController.IsShowDateTime)
                        Main\_OnNcPaint(ref m);
                    break;

Hi, that code is mysterious to me. I do have two suggestions: 1. add a font.Dispose() to clean up the font you created. Gives better memory handling. 2. if you don't do it already, modify MessageBox.Show(someString,...) to MessageBox.Show(this, someString,...) that might solve the problem. :)
