2.0.3.0 Performance/RefreshGrid sample

[Administrator]

Hi,

I just downloaded the 2.0.3.0 syncfusion package, and theres a very interesting sample in it called Performance/RefreshGrid. Thank you for this sample; it definately points out some usefull avenues for performance optimisations.

Unfortunately I''m having trouble getting the sample to run.

At line 108, a System.ExecutionEngineException is thrown.
This is what line 108 looks like:

e.Cancel = GridGdiPaint.Instance.DrawText(e.Graphics, e.DisplayText, e.TextRectangle, e.Style);

What operating system are you using? On my XP system, I can load, build and run both the CS and VB versions of that sample under .NET 1.0 and .NET 1.1?

Can you post the call stack?

That line you posted is trying to use interop to access GDI drawing code instead of the .NET GDI+ code. Have you changed the sample in some so it needs GDI+ for some reason (like drawing gradients)?

Im using windows 2000, latest SP, VS.2003, Syncfusion 2.0.3.0 installed and rebooted. Going ot try windows XP later today. The project is completely unmodified, except to convert to VS.2003. Unfortunately, the call stack isnt very informative: [] > RefreshGrid.exe!RefreshGrid.PerformanceGrid.OnDrawCellDisplayText(Syncfusion.Windows.Forms.Grid.GridDrawCellDisplayTextEventArgs e = {Syncfusion.Windows.Forms.Grid.GridDrawCellDisplayTextEventArgs}) Line 163 + 0x61 bytes C# [] RefreshGrid.exe!RefreshGrid.Form1.Main() Line 390 C# Heres the output: ''DefaultDomain'': Loaded ''c:\winnt\microsoft.net\framework\v1.1.4322\mscorlib.dll'', No symbols loaded.

It may be a font problem. We''ll try it on Win2K here.

It turns out that grid is calling the unicode version of TEXTMETRIC, and this appears not to work on Win2K. We will handle this in our code.
