<pre><code>public void SaveFormPicutreBoxToBitMapIncludingDrawings() { using (Bitmap b = new Bitmap(pictureBox1.Width, pictureBox1.Height)) { pictureBox1.DrawToBitmap(b, new Rectangle(0, 0, pictureBox1.Width, pictureBox1.Height)); string fn = @"d:\PictureBoxToBitmap\" + PbToBitmap.ToString("D6") + ".bmp"; if (File.Exists(fn)) { } else { b.Save(@"d:\PictureBoxToBitmap\" + PbToBitmap.ToString("D6") + ".bmp"); // to fix/repair give gdi error exception. PbToBitmap++; } } } </code></pre> If i move the trackBar to the right it will save the first file 000000.bmp then raise it by one next time it will save file 000001.bmp But if i move back to the left once now the variable fn is 000002.bmp wich dosent exist and it will save the previous image wich is realy 000001.bmp. What it suppose to do when i move ot the left back it should be 000001.bmp see that it exist and do nothing. If will not make this checking it will just keep saving files all the time if i move the trackBar to the right or to the left so after few times i will have more then 90 files wich are almost all the same. <h2>How can i solve it ?</h2> The variable PbtoBitmap is type of int in the top of Form1 i just started it with 0. PbToBitmap = 0; The trackBar im talking about is trackBar1 where in the scroll event im calling this SaveFormPicutreBoxToBitMapIncludingDrawings function . This is the trackBar1 scroll event: <pre><code>private void trackBar1_Scroll(object sender, EventArgs e) { currentFrameIndex = trackBar1.Value; textBox1.Text = "Frame Number : " + trackBar1.Value; wireObject1.woc.Set(wireObjectAnimation1.GetFrame(currentFrameIndex)); trackBar1.Minimum = 0; trackBar1.Maximum = fi.Length - 1; setpicture(trackBar1.Value); pictureBox1.Refresh(); button1.Enabled = false; button2.Enabled = false; button3.Enabled = false; button4.Enabled = false; button8.Enabled = false; SaveFormPicutreBoxToBitMapIncludingDrawings(); return; } </code></pre>

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.
