    <p>I'm loading an embedded font using this code:</p> <pre><code>PrivateFontCollection pfc = new PrivateFontCollection(); //declared outside this function using (Stream fontStream = GetType().Assembly.GetManifestResourceStream("NucWar.BSOD_Font.ttf")) { if (null == fontStream) { return; } int fontStreamLength = (int)fontStream.Length; IntPtr data = Marshal.AllocCoTaskMem(fontStreamLength); byte[] fontData = new byte[fontStreamLength]; fontStream.Read(fontData, 0, fontStreamLength); Marshal.Copy(fontData, 0, data, fontStreamLength); pfc.AddMemoryFont(data, fontStreamLength); Marshal.FreeCoTaskMem(data); } </code></pre> <p>And that works fine. If I throw a breakpoint down at the end I can see the font is successfully loaded. If I wire-up the <code>Paint</code> event, and use this:</p> <pre><code>bool bold = false; bool italic = false; e.Graphics.PageUnit = GraphicsUnit.Point; using (SolidBrush b = new SolidBrush(Color.Black)) { int y = 5; foreach (FontFamily fontFamily in pfc.Families) { if (fontFamily.IsStyleAvailable(FontStyle.Regular)) { using (Font font = new Font(fontFamily, 32, FontStyle.Regular)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); } y += 40; } if (fontFamily.IsStyleAvailable(FontStyle.Bold)) { bold = true; using (Font font = new Font(fontFamily, 32, FontStyle.Bold)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); } y += 40; } if (fontFamily.IsStyleAvailable(FontStyle.Italic)) { italic = true; using (Font font = new Font(fontFamily, 32, FontStyle.Italic)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); } y += 40; } if (bold &amp;&amp; italic) { using (Font font = new Font(fontFamily, 32, FontStyle.Bold | FontStyle.Italic)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); } y += 40; } using (Font font = new Font(fontFamily, 32, FontStyle.Underline)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); y += 40; } using (Font font = new Font(fontFamily, 32, FontStyle.Strikeout)) { e.Graphics.DrawString(font.Name, font, b, 5, y, StringFormat.GenericTypographic); } } } </code></pre> <p>that too works fine, the font is painted on the form 5 times as it should.</p> <p>So I find it very confusing when I use this function:</p> <pre><code>//Yes, pts is a valid size. eg 16, 20, 22, 30 private void AdjustFontSize(float pts) { int count = 0; //_yPos is a dict&lt;string, int&gt; that contains the Name of each Label control, and its original Y position // Therefore, Keys contains the Name prop of each label foreach (var lbl in _yPos.Keys) { var con = Controls[lbl] as Label; //Current label FontFamily f = pfc.Families[0]; //Get the font out of pfc. Debugging confirms that f is not null and has a font in it. //Why this no work? It works fine if I use a built in font, like "Times" con.Font = new Font(f, pts, FontStyle.Regular); //Messing with the location prop, still working on it. Probably not important con.Location = new Point(con.Location.X, (int) (_yPos[lbl] + Math.Pow(1.15, (int) pts)*count++)); } } </code></pre> <p>And the label font changes to Arial, not me desired font. What is really bothering me is that If I change <code>con.Font = ...</code> to use <code>"Times"</code> instead of <code>f</code> It correctly changes to the Times font. And on top of that, I know the font is loaded properly because the form paints correctly. By that logic, I am changing the font properly, and I'm loading the font properly, so it should work.</p>

    1. COsounds strange, is there something special with the font you loaded? I mean you can try another font file and see if it works, there may be some difference between the default text rendering of a control with the custom drawing with GDI+.

    2. COas far as I can tell, its just a normal TTF. Ill give another file a go and see what happens.

    3. COYour AdjustFontSize method is setting the Font for all your labels by creating new fonts, but when the labels are redrawn, your paint logic uses the original fonts that you loaded.

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.
