在我的C#应用程序中,我正在尝试生成打印预览而屏幕上没有显示进度对话框.
我相信你可以使用PrintDocument.PrintController来打印真实的(即不是打印预览),但是在执行打印预览时它似乎不起作用.
我的代码如下:
public FrmDeliveryNotePrintPreview(DeliveryNote deliveryNote)
{
InitializeComponent();
this.Text = "Delivery Note #" + deliveryNote.Id.ToString();
// The print preview window should occupy about 90% of the
// total screen height
int height = (int) (Screen.PrimaryScreen.Bounds.Height * 0.9);
// Making an assumption that we are printing to A4 landscape,
// then adjust the width to give the correct height:width ratio
// for A4 landscape.
int width = (int) (height / 1.415);
// Set the bounds of this form. The PrintPreviewControl is
// docked, so it should just do the right thing
this.SetBounds(0, 0, width, height);
PrinterSettings printerSettings = new PrinterSettings();
PrintDeliveryNotes pdn = new PrintDeliveryNotes(
new DeliveryNote[] { deliveryNote },
printerSettings);
PrintDocument printDocument = pdn.PrintDocument;
printDocument.PrintController = new PreviewPrintController();
ppcDeliveryNote.Document = printDocument;
}

除了显示打印预览进度对话框之外,打印预览完全按照我的要求工作.
建议好吗?
这对我有用:
将文档的printcontroller设置为a StandardPrintController.
static class Program
{
static void Main()
{
PrintDocument doc = new PrintDocument();
doc.PrintController = new StandardPrintController();
doc.PrintPage += new PrintPageEventHandler(doc_PrintPage);
doc.Print();
}
static void doc_PrintPage(object sender, PrintPageEventArgs e)
{
e.Graphics.DrawString("xxx", Control.DefaultFont, Brushes.Black, new PointF(e.PageBounds.Width / 2, e.PageBounds.Height / 2));
}
}

我讨厌回答自己的问题,但解决方案就在我面前。
由于我已经编写了打印送货单的功能,因此我的下一步是提供屏幕副本(即无意打印硬拷贝)。打印预览对话框似乎是一个简单的出路。
最后,我只是创建了一个自定义表单并直接在其上绘制,看不到打印预览控件。
不幸的是,我过于专注于尝试让打印预览对话框按照我想要的方式运行,而不是着眼于更大的问题。
