    <p>Currently I have a third party control that generates a Metafile. I can save the .wmf file to disk with out issue. The problem is how do I render the Metafile as a Tiff file. </p> <p>Currently I have the following code to get my metafile and save it. </p> <pre><code> Dim mf As Metafile = page.GetImage(TXTextControl.Page.PageContent.All) Dim enhMetafileHandle As IntPtr = mf.GetHenhmetafile() Dim h As IntPtr Dim bufferSize As UInteger = GetEnhMetaFileBits(enhMetafileHandle, 0, h) Dim buffer(CInt(bufferSize)) As Byte GetEnhMetaFileBits(enhMetafileHandle, bufferSize, buffer) Dim msMetafileStream As New MemoryStream msMetafileStream.Write(buffer, 0, CInt(bufferSize)) Dim baMetafileData() As Byte baMetafileData = msMetafileStream.ToArray Dim g As Graphics = Graphics.FromImage(mf) mf.Dispose() File.WriteAllBytes("c:\a.wmf", baMetafileData) </code></pre> <p>end sub</p> <p> _ Public Shared Function GetEnhMetaFileBits( ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData As IntPtr) As UInteger End Function</p> <pre><code>&lt;System.Runtime.InteropServices.DllImportAttribute("gdi32.dll", EntryPoint:="GetEnhMetaFileBits")&gt; _ Public Shared Function GetEnhMetaFileBits(&lt;System.Runtime.InteropServices.InAttribute()&gt; ByVal hEMF As System.IntPtr, ByVal nSize As UInteger, ByVal lpData() As Byte) As UInteger End Function </code></pre> <p>I've tried all sort of IMAGE and Graphic calls and just can't save the meta file as a .tiff. Any suggestions would be great. I even tried to create a new bitmap and draw the metafile onto it. I always end up with a GDI exception being thrown. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
