从数据库获取数据，竟然是空值，达人进来指导下，谢谢
本帖最后由 corain77 于 2010-9-25 14:43 编辑hdbc = DBConnect ("DSN=CVI SQL TEST");
if (hdbc <= 0) {ShowError(); }//goto Error;}
从控件读取用户名和密码
//从数据库中获取数据进行匹配
hstmt = DBActivateSQL (hdbc, "SELECT * FROM USER WHERE User_Name='username'");
if (hstmt <= 0) {ShowError();}
resCode = DBBindColChar (hstmt,1, 50, name, &name_stat,"");
if (resCode != DB_SUCCESS) {ShowError();}
resCode = DBBindColChar (hstmt,2, 50, psword, &psword_stat,"");
if (resCode != DB_SUCCESS) {ShowError();}
//判断密码输入是否正确
if ((strcmp (username, name) ==0)&&(strcmp (passwordstring, psword) == 0))
{
DiscardPanel(panelHandle);
SetCtrlVal(main_panelHandle, MAIN_PANEL_STRING,name);
DisplayPanel(main_panelHandle);
}
else
{
MessagePopup ("登录失败", "用户名不存在或密码不正确！");
}
获取的name和psword都是空值，数据库已经连上，可以插入数据，不知道怎么回事了
数据库表如下：
User_Name Pass_Word
