    <p>When I run my application the following error get's thrown in my face "A generic error occurred in GDI+." I've looked around and seen people have similar errors, but have found no real solution, or it is a real pain in the butt to implement. And those that have not gotten a solution have not posted their code.</p> <p>So I thought I might as well give it a shot and throw another thread up about how to fix this error. This is my Code &amp; Error</p> <pre><code> Random r = new Random(); DirectoryInfo di = new DirectoryInfo(folderbrowser.SelectedPath); FileInfo[] fi = di.GetFiles().Where(f =&gt; extensions.Contains(f.Extension.ToLower())).ToArray(); for (int i = 0; i &lt; imageCount; i++) { int img1 = r.Next(imageCount); int img2 = r.Next(imageCount); while (img2 == img1) img2 = r.Next(imageCount); pic1.Image = Image.FromFile(fi[img1].FullName); pic2.Image = Image.FromFile(fi[img2].FullName); Image i1 = pic1.Image; Image i2 = pic2.Image; Bitmap bitmap = new Bitmap(i1.Width + i2.Width, 1080); using (Graphics g = Graphics.FromImage(bitmap)) { g.DrawImage(i1, 0, 0); g.DrawImage(i2, i2.Width, 0); } bitmap.Save(@"C:\TEST\Image_"+i.ToString()); } </code></pre> <p>And here's the Error code</p> <pre><code>System.Runtime.InteropServices.ExternalException was unhandled Message=A generic error occurred in GDI+.

Am I the same boat as the others and have to type a ridiculously complex code to solve this problem, or have I made a simple mistake and it's easy to correct?</p> <p>If you want to test it yourself if that might somehow help, here's a link to the <a href="https://dl.dropbox.com/u/14970061/WallpaperMerger.exe" rel="nofollow">Debug Build</a></p> <p>Simply tick "Use Multiple Files", select a folder containing image files (C:\Users\Public\Pictures\Sample Pictures) for instance. Hit Merge.</p> <p>I'd like to add that I use Bitmap.Save in this function, and it works flawlessly.</p> <pre><code> Bitmap bitmap = new Bitmap(pic1.Image.Width + pic2.Image.Width, 1080); using (Graphics g = Graphics.FromImage(bitmap)) { g.DrawImage(pic1.Image, 0, 0); g.DrawImage(pic2.Image, pic1.Image.Width, 0); } if (savepicfile.ShowDialog() == DialogResult.OK) bitmap.Save(savepicfile.FileName); </code></pre> <p>In the above function files are loaded like this:</p> <pre><code> DialogResult result = pic1file.ShowDialog(); if (result == DialogResult.OK) pic1.Image = Image.FromFile(pic1file.FileName); </code></pre> <p>Something else worth mentioning is that "picX" is a "System.Windows.Forms.PictureBox" object.</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
