如何使用 DrawText() 在已知句柄的给定窗口中写入文本? [英] how to use DrawText() to write text in a given window whose handle is known?

问题描述

我想知道如何使用 Windows API 在特定窗口上从窗口中的给定位置开始写入文本.

I want to know how to write text on a particular window starting at a given location in the window using the Windows API.

例如，如果要写入文本的窗口内的坐标是 (x,y) = (40,10) 那么我需要做什么才能将一行文本写入该位置的特定窗口在窗口?

For example if the coordinates within the window where the text is to be written are (x,y) = (40,10) then what do I need to do to write a line of text to a particular window at that location in the window?

推荐答案

假设您的窗口名称是hwnd"，并且您想在该窗口上以 x,y 坐标写入的文本存储在消息"中，其中

Suppose your window name is "hwnd" and the text which u want to write on that window at x,y coordinate is say stored in "message" where

LPCWSTR message=L"My First Window"; then

RECT rect;
HDC wdc = GetWindowDC(hwnd);
GetClientRect (bgHandle, &rect) ;
SetTextColor(wdc, 0x00000000);
SetBkMode(wdc,TRANSPARENT);
rect.left=40;
rect.top=10;
DrawText( wdc, message, -1, &rect, DT_SINGLELINE | DT_NOCLIP  ) ;
DeleteDC(wdc);  

就是这样......记住这只是一个例子.

Thats it.. remember this is just one example.
