来自文本字段win32 api的整数值

Question

我是一个noob拼写出来会有所帮助。 使用c ++ win32 api我需要从文本字段中获取一个int变量来控制for循环。

我有我的按钮，文本字段和变量全部设置。我只需要＆＃34; Textfield1＆＃34;给予＆＃34; int LVL1＆＃34;和＃34; Textfield2＆＃34;给予＆＃34; int LVL2＆＃34;。

我基本上不知道从哪里开始，尝试在这里和其他地方搜索并继续获取char或java答案。

我到目前为止我做错了什么？ GetDlgItemInt（TextField1，LVL1，NULL，false）; 但是没有改变价值。

CODE：

案例WM_CREATE：{TextField1 = CreateWindow（＆＃34; Edit＆＃34;，＆＃34; Current Lvl＆＃34;，

TextField2 = CreateWindow（＆＃34; EDIT＆＃34;，＆＃34; Desired Lvl＆＃34;，

Button = CreateWindow（＆＃34; BUTTON＆＃34;，＆＃34;提交＆＃34;，

中断;案例WM_COMMAND：

if（LOWORD（wParam == 1））{system（＆＃34; echo \＆＃34; Submit \＆＃34; Button＆＃34;）; ///仅用于调试工具int souls [793] = {0,0,673,690,707,724,741,758,775,793,811,829,847,1039,1238,1445,1660,1883，

Answer 1

GetDlgItemInt完全符合您的要求。

Answer 2

我总是得到字符串并将其转换为int。看看documentation for GetWindowText()。

首先，检索文本字段窗口的句柄：

HWND hText = GetDlgItem(hParent, ID_TEXT_FIELD1); // hParent is parent window of text field

然后，您希望获取文本的长度以了解要分配的内存量并检查最大/最小长度：

int len = GetWindowTextLength(hText);

现在分配一个缓冲区以从字段中检索字符串。

char* buf = new char[len + 1];

并检索文字：

int ret = GetWindowText(hText, buf, sizeof(buf));

根据文档，如果函数成功，ret将大于零，所以如果是，则继续并将缓冲区转换为整数：

int LVL1 = atoi(buf); // atoi() is from stdlib.h

假设您使文本字段仅接受数字或正确解析缓冲区，这将起作用。所以现在你有了整数值，你也可以为LVL2做同样的事情。

不要忘记释放缓冲区：

delete[] buf;
