l 获得hicon

m_hIcon = AfxGetApp()->LoadIcon(IDI_ICON3);

l ExStyle的获得

DWORD dwExStyle = LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES | /*LVS_EX_SUBITEMIMAGES |*/

m_List1.SetExtendedStyle(LVS_EX_FULLROWSELECT|LVS_EX_GRIDLINES);

Extended List-View Styles

l 标准的list初始

static const struct

{

UINT nColHdrId;

int nFormat;

int nWidth;

} colData[] = {{IDS_NULL, LVCFMT_LEFT, 30},

{IDS_NULL, LVCFMT_LEFT, 30},

{IDS_LOG_COLUMN_MAIL_SENDER, LVCFMT_LEFT, 100},

{IDS_LOG_COLUMN_MAIL_RECEIVE_TIME, LVCFMT_LEFT, 170},

{IDS_LOG_COLUMN_MAIL_TITLE, LVCFMT_LEFT, 180}};

const int nColCount = sizeof colData / sizeof colData[0];

for (int nColumn = 3; nColumn < nColCount; nColumn++)

{

strColumn.LoadString(colData[nColumn].nColHdrId);

m_lcLogListCtrl.InsertColumn(nColumn, strColumn, colData[nColumn].nFormat,

colData[nColumn].nWidth);

// if (nColumn > 0) m_lcLogListCtrl.EnableColumnHiding(nColumn, true);

}

l 命令的定义

///////////////////////////////////////////////////////////////////////////////

// Head of all commands

///////////////////////////////////////////////////////////////////////////////

#define DIR_CMD_BASE 0x00000000

typedef struct _tag_CMD_HEAD

{

DWORD dwCmd; // command type

int nBufSize; // command buffer size

BYTE pBuf[0]; // command buffer

_tag_CMD_HEAD()

{

ZeroMemory(this, sizeof(_tag_CMD_HEAD));

};

}

CMD_HEAD, *PCMD_HEAD;

///////////////////////////////////////////////////////////////////////////////

// This Message is From MAIL Client To Dir-Server :

// Upload A Attach File:

///////////////////////////////////////////////////////////////////////////////

#define CMD_MAIL_CLT_UPLOAD_FILE_REQ DIR_CMD_BASE+4019

typedef struct _tag_Cmd_Mail_Clt_Upload_File_Req

{

// char szUser[M_ACCOUNT_SIZE];

// CHAR szAttachFile[MAX_LENGTH_ATTACH_FILE_PATH];

_tag_Cmd_Mail_Clt_Upload_File_Req()

{

ZeroMemory(this, sizeof(_tag_Cmd_Mail_Clt_Upload_File_Req));

};

}

Cmd_Mail_Clt_Upload_File_Req, *PCmd_Mail_Clt_Upload_File_Req;

#define CMD_MAIL_CLT_UPLOAD_FILE_RET DIR_CMD_BASE+4020

typedef struct _tag_Cmd_Mail_Clt_Upload_File_Ret

{

CHAR szUser[M_ACCOUNT_SIZE];

}

Cmd_Mail_Clt_Upload_File_Ret, *PCmd_Mail_Clt_Upload_File_Ret;

使用

Cmd_Mail_Update_Req strTemp;

strTemp.dwCltExistedMails=12345;

PCMD_HEAD pHead = (PCMD_HEAD)new BYTE[sizeof(CMD_HEAD)+sizeof(Cmd_Mail_Update_Req)];

memset(pHead, 0, sizeof(CMD_HEAD)+sizeof(Cmd_Mail_Update_Req));

pHead->dwCmd = CMD_MAIL_UPDATE_REQ;

pHead->nBufSize = sizeof(CMD_HEAD)+ sizeof(Cmd_Mail_Update_Req);

memcpy(pHead->pBuf, &strTemp, sizeof(Cmd_Mail_Update_Req));

TRACE("[CltMail]-----Ready to Send CMD_MAIL_UPDATE_REQ!");

if (FALSE==m_pTransClt->SendToServer(pHead, pHead->nBufSize)) {

TRACE("[CltMail]-----Send CMD_MAIL_UPDATE_REQ Failed!");

}

else TRACE("[CltMail]-----Send CMD_MAIL_UPDATE_REQ Success!");

l Clable可以改变标签底色

m_staticReNewPwd.SetTextColor(RGB(0, 0, 0)).SetTransparent(TRUE);

m_staticOldPwd.SetTextColor(RGB(0, 0, 0)).SetTransparent(TRUE);

m_staticNewPwd.SetTextColor(RGB(0, 0, 0)).SetTransparent(TRUE);

CAdvancedButton m_btnClose;

CAdvancedButton m_btnQuit;

CAdvancedButton m_btnDownLoadFile;

l 移动自己定义的窗口

void MailListDlg::OnMouseMove(UINT nFlags, CPoint point)

{

if(nFlags & MK_LBUTTON)

{

SendMessage(WM_SYSCOMMAND,SC_MOVE | HTCLIENT,0);

}

CDialog::OnMouseMove(nFlags, point);

}

l 设置透明区域

//Paint the Common Control
