问题描述
一个窗口句柄 HWND hwnd 已经可用，现在我想打印一个格式字符串
到这个 hwnd 。我不太熟悉Windows API，非常感谢您的帮助。
A window handle HWND hwnd has already been available, now I want to print a format string into a window described by this hwnd. I am not familiar with Windows API, Thanks very much for your help.
例如：
num = 23;
printFunction(hwnd, "number is %d", num);
有没有功能来解决这个问题？谢谢！
Is there a function to solve this problem? Thank you!
UPDATE ：在使用IDA Pro SDK时遇到此问题。
UPDATE: I encounter this problem during using IDA Pro SDK.
创建以下示例子窗口：
HWND hwnd = NULL;
TForm *form = create_tform("Sample subwindow", &hwnd);
我使用 SendMessage（hwnd，WM_SETTEXT，NULL，（LPARAM）hello世界）; 在子窗口中打印 hello world 字符串，但是如果我想打印格式字符串到这个子窗口， / p>
I use SendMessage(hwnd, WM_SETTEXT, NULL, (LPARAM)"hello world"); to print hello world string in the subwindow, but what should I do if I want to print format string into this subwindow?
推荐答案
sprintf(myString, "number is %d", num);
SendMessage(hwnd, WM_SETTEXT, NULL, (LPARAM)myString);
