问题描述
我正在尝试在同一个文档中打印3页，但它只打印我的最后一页。
I'm trying to print 3 pages in the same document, but it is only printing my last one.
private void button4_Click(object sender, EventArgs e)
{
if (textBox1.Text != "" || textBox2.Text != "" || richTextBox1.Text != "" || Imagemfoot_1.Image != null || Imagemfoot_2.Image != null || Imagemfoot_3.Image != null || Imagemhead_1.Image != null || Imagemhead_2.Image != null || Imagemhead_3.Image != null)
{
PrintDocument tPrinter = new PrintDocument();
tPrinter.PrintPage += new PrintPageEventHandler(printDocument1_PrintPage);
tPrinter.Print();
}
}
我的尝试：
这是我的代码：
What I have tried:
this is my code:
switch (PageNumber)

{
e.Graphics.DrawImage(Imagemhead_3.Image, x2, y2, width2, height2);
}
else if (numericUpDown1.Value == 2)
{
e.Graphics.DrawImage(Imagemhead_1.Image, x3, y3, width3, height3);
e.Graphics.DrawImage(Imagemhead_2.Image, x4, y4, width4, height4);
}
/// Titulo

推荐答案
嗯...第2页& 3不要;打印任何东西，所以它们都是空白的。
除此之外，使用调试器做两件事：
1）检查值在按钮单击事件处理程序中的PageNumber。你没有显示任何设置或重置它的代码，所以它可以这么简单。
2）在PrintPage事件处理程序的顶部放置一个断点并通过代码查找确切地说它的位置。
我们不能为您做到这一点 - 我们无法访问您的机器！
Well ... pages 2 & 3 dont; print anything, so they will be blank.
Other than that, use the debugger to do two things:
1) Check the value of PageNumber in your button click event handler. You don't show any code for setting or resetting it, so it could be as simple as that.
2) Put a breakpoint at the top of the PrintPage event handler and step though the code to find out exactly where it is going.
We can't do that for you - we don't have any access to your machine!
