User (Legacy) Posted August 1, 2006 Report Share Posted August 1, 2006 I am experiencing a strange null exception intermittedly when using a radial gauge that has an inner gauge. its only on a radial gauge with an inner digital panel and its not every time .. but frequent enough to cause my program grief and grind it to a halt. I have a dashboard with a number of gauges .. but if I obscure a radial gauge ( that has an inner digital panel ) with another window ( say a IE window ) I get the following error System.NullReferenceException: Object reference not set to an instance of an object. at c0.b(an A_0) at an.k() at ei.a(an A_0, gp A_1, ef A_2) at ef.a(hd A_0, ht A_1) at ef.a(hd A_0, ht A_1) at ef.a(hd A_0) at hl.b(hd A_0) at ChartFX.WinForms.Gauge.BaseGauge.a(hd A_0) at ChartFX.WinForms.Gauge.Indicator.d() at ChartFX.WinForms.Gauge.Indicator.a(Value A_0, Boolean A_1) at ChartFX.WinForms.Gauge.Indicator.set_Value(Object value) at ChartFX.WinForms.Gauge.Gauge.set_MainValue(Object value) at OFS_Console_B.ofsConsole.KPI_ScreenUpdate(KPI KPI_type) in C:\Documents and Settings\philip\My Documents\Visual Studio 2005\Projects\OFS Console B\OFS Console B\Form1.cs:line 633 its intermittent and only happens to radial gauge with an inner digital panel ... I tacked together a small test app with an windows timer event and put a radial gauge with digital panel in it but completely failed to reproduce the exception. If I dont obscure that particular gauge then my app runs for days, behaving normally ... I'm quite perplexed .... has this behaviour been seen before? regards Bob ..
