多对话框管理

新建两个对话框

• 设置焦点顺序，使用ctrl+d，然后点选顺序。
• IDOK是个特殊的ID，回车键会默认点击它。
• ESC默认是IDCANCEL
• strcmp是C语言的字符串比较函数。

代码：

// test3.cpp : Defines the entry point for the application.
//

#include "stdafx.h"
#include "resource.h"
#include "stdio.h"

BOOL CALLBACK MainProc(
                       HWND hwndDlg,
                       UINT uMsg,
                       WPARAM wParam,
                       LPARAM lParam)
{
    char s[256];
    sprintf(s,"uMsg=0x%x,wParam=%d,lParam=%d \n", uMsg,wParam,lParam);
    OutputDebugString(s);
    switch(uMsg){
    case WM_COMMAND:
        {
            switch (LOWORD(wParam)){
            case IDCANCEL:
                EndDialog(hwndDlg,IDCANCEL);
                return FALSE;
            case IDOK:
                EndDialog(hwndDlg,IDCANCEL);
                return FALSE;
            }

            return FALSE;
        }
    }
    return FALSE;

}
BOOL CALLBACK LoginProc(
                        HWND hwndDlg,
                        UINT uMsg,
                        WPARAM wParam,
                        LPARAM lParam)
{
    switch(uMsg){
    case WM_COMMAND:
        {
            switch (LOWORD(wParam)){
            case IDCANCEL:
                EndDialog(hwndDlg,IDCANCEL);
                return FALSE;
            case IDOK:
                {
                    char sName[20];
                    char sPass[20];
                    GetDlgItemText(hwndDlg,IDC_NAME,sName,sizeof(sName));
                    GetDlgItemText(hwndDlg,IDC_PASS,sPass,sizeof(sPass));
                    if(0==strcmp("admin",sName) && 0==strcmp("pass",sPass)){
                        EndDialog(hwndDlg,IDOK);
                    }
                    else
                        MessageBox(hwndDlg,"pass error","prompt",MB_OK);
                    return FALSE;
                }
            }

            return FALSE;
        }
    }
    return FALSE;
}


int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
    int nRet = DialogBox(hInstance,(LPCSTR)IDD_DIALOG_LOGIN,NULL,LoginProc);
    if(nRet==IDCANCEL)
        return -1;
    DialogBox(hInstance,(LPCSTR)IDD_DIALOG_MAIN, NULL,MainProc);
    return 0;
}

运行效果：

输入 admin password，回车进入主界面。

添加删除item的实现代码：

void CTest4Dlg::OnAdd() 
{
    CString str;
    GetDlgItemText(IDC_NUMB,str);
    CListCtrl* pList = (CListCtrl*)GetDlgItem(IDC_LIST);
    int nCount = pList->GetItemCount();
    pList->InsertItem(nCount,str);
    GetDlgItemText(IDC_NAME,str);
    pList->SetItemText(nCount,1,str);
    GetDlgItemText(IDC_SALARY,str);
    pList->SetItemText(nCount,2,str);
}

void CTest4Dlg::OnDel() 
{
    CListCtrl* pList = (CListCtrl*)GetDlgItem(IDC_LIST);
    int nSel = pList->GetSelectionMark();
    if(nSel<0){
        AfxMessageBox("please select one row.");
    }
    pList->DeleteItem(nSel);

}
