Mike,

Thanks you. I have however a few problems converting this pure VB code to VB.NET. I was able to understand that the VB line:

Dim WithEvents m_PrintDocument As PrintDocument

should be converted to:

Dim WithEvents m_PrintDocument As System.Drawing.Printing.PrintDocument

But could you help me with the following?

1. At the line:

Dim bm_gr As Graphics = me_gr.FromImage(bm)

it complains that me_gr.FromImage(bm), "Access of shared member, constant member, ... through an instance; qualifying expression will not be evaluated" .

2. At the line:

Dim me_hdc As IntPtr = GetWindowDC(Me.Handle)

it complains that
"PInvokeStackImbalance was detected
Message: A call to PInvoke function 'dlr_cost!dlr_cost.Form1::GetWindowDC' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature."


Thanks in advance
