那么反过来怎么转呢？

博主~应该做一个演示嘛

Oh,Year.thats right.

谢谢啊 一时蒙了

先试试看

1楼正解

你的这个方法行不通.

sb a 无法运行

我试过了，还是不行啊？

test

verry good

USES_CONVERSION;
LPCTSTR szr = A2W( szDomainUrl );
cstr_domainCheck += szr;

LPCTSTR可直接加在CString 后面. cstr_test += szr;

cstring 转 TCHAR 在unicode下碰到的.
CString bodytext = "hello";
TCHAR szTemp[1024];
wcscpy(szTemp,bodytext);

CString 转 int
_ttoi(cstr_test);

std::string str_std = "xxx";
CString cstr_mfc(str_std.c_str());
此为正确答案

I have gotten a few questions on converting other data types into strings. While the obvious ones like char * are done for you, numbers are not. To solve this problem you can use an ostringstream. This is done by sending the variable to the stream, and then returning the stream as a string. Included below is a function called ToString(const T &arg); that takes an argument of ANY type and converts it into a string if such a conversion is allowed. The function and an example use of it are shown below:

#include < string >
#include < sstream >
#include < iostream >

using std::cout;
using std::endl;
using std::string;
using std::ostringstream;

template < class T >
string ToString(const T &arg)
{
ostringstream out;

out << arg;

return(out.str());
}

int main(int argc, char **argv)
{
string integer = ToString(1234);
string floating_point = ToString(1238.1239);
string some_string = ToString("Why would you do this?");

cout << integer << floating_point << some_string << endl;

string combine_all = integer + floating_point + some_string;

cout << combine_all << endl;

return(0);
}

std::vector<int> IntTest;

for (int i = 0; i < 10; ++i)
{
IntTest.push_back(i);
}

bool bExist = binary_search(IntTest.begin(), IntTest.end(), 2);

std::cout << bExist << std::endl;



/*for (std::vector<int>::iterator iter = IntTest.begin(); iter != IntTest.end(); ++iter)
{
std::cout << *iter << std::endl;
}*/

DIV id='mDiv' style='BORDER-RIGHT: blue thin; OVERFLOW-Y: auto; OVERFLOW-X: hidden; BORDER-TOP: blue thin; BORDER-LEFT: blue thin; WIDTH: 800px; BORDER-BOTTOM: blue thin; HEIGHT: 137px'

String StrCtolID = BtSearch.ClientID;
作用: 如果该控件在一个userctrol中，着它的名字发生变化，如果用
BtSearch.ClientID则可动态取出该控件的ID.

onBlur 失去输入焦点时的事件.

删除:
ListObj.remove(3);

设置选中状态 :
var ListObj = document.all.DropDownList1;
ListObj.options[0].selected = true;

<script>
function Test()
{
var ListObj = document.all.DropDownList1;

/* 遍历DropDownList
for (var i = 0; i < ListObj.length; ++i)
{
alert(ListObj.options[i].value);
}*/

var newOption = document.createElement("OPTION");　
　　 　 newOption.text = "city";　
　　 　 newOption.value = "city";　
　　 　 ListObj.options.add(newOption);　
}

function SelectedChange()
{
// 获取选中的值
var selectedValue = document.all.DropDownList1.value;
}
</script>

为DropDownList1添加javascript事件
this.DropDownList1.Attributes.Add("onchange","Test()");

statesList.options.length = 0; //重置州下拉列表

Label1.Text = (string)TFunction.Invoke(TObj, ObjList);
若无参数，则为 (String)TFunction.Invoke(TObj, null);
