 VC++獲取IDC_EDIT的7種方法

http://blog.csdn.net/baizengfei/article/details/7997618

 

//第一種方法

int number1, number2, number3;

char char1[10], char2[10], char3[10];

GetDlgItem(IDC_EDIT1)->GetWindowText(cahr1, 10);

GetDlgITem(IDC_EDIT2)->GetWindowText(char2, 10);

 

number1 = atoi(char1);

number2 = atoi(char2);

number3 = number1 +number2;

 

itoa(number3, char3, 10);

GetDlgItem(IDC_EDIT3)->SetWindowText(cahr3);

---

//第二種方法

char char1[10], char2[10], char3[10];

int number1, number2, number3;

 

GetDlgItemText(IDC_EDIT1, char1, 10);

GetDlgITemText(IDC_EDIT2, char2, 10);

 

number1 = atoi(char1);

number2 = atoi(char2);

number3 = number1 + number2;

itoa(number3, char3, 10);

SetDlgItemText(IDC_EDIT3, char3);

---

//第三種方法

int number1, number2, number3;

number1 = GetDlgItemInt(IDC_EDIT1);

number2 = GetDlgITemInt(IDC_EDIT2);

number3 = number1 + number2;

 

SetDlgItemInt(IDC_EDIT3, number3);

---

//第四種方法

*在ClassWizard中的Member中找到IDC_EDIT1和IDC_EDIT2的Control IDs雙擊IDC_EDIT1和IDC_EDIT2打開Add MemberVariable

添加MemberVariableName的新名字（m_number1)

CateGory:Value;

Variable Type: Int;

OK!

void CTest_3Dlg::OnButton1()

{

        UpdateData();

m_number3 = m_number1 + m_number2;

UpdateData(FALSE);

 

DoDateExChange;ＭＳＤＮ說明這個函數程序代碼從來是不調用的，而是由我們通過ＣＷｎｄ類的另一個函數來調用的（ＵｐｄａｔｅDａｔａ（））；來實現的。

}

---

//第五種方法

int number1, number2, number3;

char char1[10], char2[10], char3[10];

 

m_ctrlEDIT1.GetWindowText(char1, 10);

m_ctrlEDIT2.GetWindowText(char2, 10);

number1 = atoi(char1);

number2 = atoi(char2);

number3 = number1 + number2;

itoa(number3, char3, 10);

m_ctrlEDIT3.SetWindowText(char3);

---

//第六種方法

int num1, num 2, num3;

char ch1[10], ch2[10], ch3[10];

::SendMessage(GetDlgItem(IDC_EDIT1)->m_Hwnd),  WM_GETTEXT, 10, (LPARAW)ch1);

::SendMessage(m_ctrlEDIT2.m_Hwnd),  WM_GETTEXT, 10, (LPARAW)ch2);

num1 = atoi(ch1);

num2 = atoi(ch2);

num3 = num1  + num2;

m_ctrlEDIT3.SendMessage(WM_SETTETXT,  10, (LPARAW), ch3);

---

//第七種方法；

int num1, num2, num3;

char ch1[10], ch2[10], ch3[10];

SendDlgItemMessage(IDC_EDIT1, WM_GETTEXT, 10, (LPARAM)ch1);

SendDlgItemMessage(IDC_EDIT2, WM_GETTEXT, 10, (LPARAM)ch2);

num1 = atoi(ch1);

num2 = atoi(ch2);

num3 = num1 + num2;

SendDlgItemMessage(IDC_EDIT3, WM_SETTEXT, 10, (LPARAM)ch3);
