在Windows窗体上以C语言打印 [英] Printing on Windows form in C

问题描述

我正在尝试在Windows窗体上打印事物列表，但我无法做到这一点.我正在使用textout当前进行打印，但每次仅打印一行.

这是我在WM_PAINT下所做的

 大小写 WM_PAINT:
{
   // 在窗口上绘制

   hdc = BeginPaint(hMainWindow，& pStruct);
   GetClientRect(hMainWindow，& amp; clientArea);

   // 输出位置
   TextOut(
       hdc，//  DC的句柄
       nXStart，// 起始位置的x坐标
       nYStart，// 起始位置的y坐标
       textBuff，// 字符串
       MAX_BUFF_LEN // 字符数
    );
} 

基本上我想将所有东西打印在新行上.我无法做到这一点.我添加到textBuff的所有内容都打印在一条水平线上.

使用DrawText代替TextOut.

并将所有行分组为一个唯一的字符串，并在每行末尾添加新的行字符:"\n".或"\r\n"表示回车+新行.

Hi,

I am trying to print a list of things on the windows form but I am not able to do it. I am using textout to print currently but it only prints one line every time.

This is what I have done under WM_PAINT

case WM_PAINT:
{
   // Draw on Window

   hdc = BeginPaint(hMainWindow, &pStruct);
   GetClientRect(hMainWindow, &clientArea);

   // Output position
   TextOut(
       hdc,          // handle to DC
       nXStart,      // x-coordinate of starting position
       nYStart,      // y-coordinate of starting position
       textBuff,       // character string
       MAX_BUFF_LEN  // number of characters
    );
}

Basically I want a list of things to be printed on a new line.I am not able to do that.Everything I add to the textBuff gets printed in one horizontal line.

解决方案

Use DrawText instead of TextOut.

And group all your lines in one unique string and add a new line character at the end of each line: "\n". Or "\r\n" for carriage return + new line.
