项目字体设置
字体：Courier New，大小：11
把显示项列表中的条目全部设置成“粗体”。
System.TimeSpan sp = new TimeSpan(0,100,0);//100分钟
sp.ToString();//输出"01:40:00"
项目黙认字体一般设为10号字体，以适应不同的分辨率。

捆绑的
crystal report
有什么限制？
是否需要付费买许可
有限制,有并发数限制,要在部暑的服务器里的注册表做修改,否则访问过量就出错误页
具体为修改下面两个键的值。
HKEY_LOCAL_MACHINE;SOFTWARE;Crystal Decisions;10.0;Report Application
Server;InprocServer;PrintJobLimit
修改为1000
还有一个HKEY_LOCAL_MACHINE;SOFTWARE;Crystal Decisions;10.0;Report Application
Server;Server;PrintJobLimit 也修改为1000

if
(e.RowHandle>=0)
{
e.Info.DisplayText=e.RowHandle.ToString();
}
else
if
(e.RowHandle<0 && e.RowHandle>-1000)
{
e.Info.Appearance.BackColor=System.Drawing.Color.AntiqueWhite;
e.Info.DisplayText="G"+e.RowHandle.ToString();
}
}
摘录：《程序员秘书》－－源代码－－数据库－－图片文件写入数据库并读出
9、在Form1.cs的视图设计器中，选中button2，在属性框中选中事件，双击Click，在Form1.cs的代码设计器中，添加修改如下代码
private void button2_Click(object sender, EventArgs e)
{
try
{
OpenFileDialog openFileDialog1 = new OpenFileDialog();
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string FileName = Path.GetFileName(openFileDialog1.FileName);
if (listBox1.Items.IndexOf(FileName) == -1)
{
Stream myStream = openFileDialog1.OpenFile();
int length = (int)myStream.Length;
byte[] bytes = new byte[length];
myStream.Read(bytes, 0, length);
myStream.Close();
dataset.Tables[0].Rows.Add(new object[] { FileName, bytes });
adapter.Update(dataset, "Pic_Table");//保存到数据库
listBox1.Items.Add(dataset.Tables[0].Rows[dataset.Tables[0].Rows.Count - 1][0].ToString());
listBox1.SelectedIndex = listBox1.Items.Count-1;
MessageBox.Show(this, "已经添加了一个图片。", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
MessageBox.Show(this, "添加的图片名称已经存在。", "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
catch (Exception Mye)
{
MessageBox.Show(this, Mye.Message, "信息提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
你可以先将PictureBox的图片保存为一个临时文件，再用上面的方法处理就OK了。
