如何在MFC中将CString转换为UINT [英] How to convert CString to UINT in MFC

问题描述

我是MFC的新手，我在这里将CString转换为UINT，我试过了

 UINT iEditId = _ttoi（（LPCSTR）sTempString）; 

sTempString值为IDC_EDIT5，我的iEditId = 0。

我无法将其转换为正确的值。

解决方案

谢谢你们的建议。经过大量搜索，我找到了解决方案。实际上我想要将一组唯一ID分配给一组动态生成的CEdit对象，所以我打算从CString转换为UINT。如果我使用以下行，其中iEditId值为1005（来自resource.h）



unsigned int iEditId = IDC_EDIT5;



所以下次我可以通过增加变量iEditId来增加ID值。



For（iIndex = 0; iIndex< = 5; iIndex ++ ）

{

pEdit [iIndex] - >创建（WS_CHILD | WS_VISIBLE | WS_DLGFRAME | ES_AUTOHSCROLL | WS_TABSTOP，CRect（110，（30 + iSize * 30），260 ，（50 + iSize * 30）），this，iEditId + iIndex）;

}

此代码正常工作并返回12：

 CString abc = _T（  12/12/2014< /跨度>）; 
  int  date = _ttoi（abc.Left（ 2 ））; 

您肯定不希望整数值为IDC_EDIT5，而是CEdit的内容的整数值，不要你呢？

你正在以错误的方式使用标签： IDC_EDIT5 已在你的一个头文件中定义，喜欢：

  #define IDC_EDIT5 1005  

你只是按原样使用该标签来获取它的值，可能得到如下项目：

 item = GetDlgItem（hDlg，IDC_EDIT5）; 

I am new to MFC and here i am converting CString to UINT, I have tried

UINT iEditId = _ttoi((LPCSTR)sTempString); 

sTempString value is "IDC_EDIT5" and I am getting iEditId=0.
I can't convert it into proper value.

解决方案

Thank you guys for your suggestions. I found the solution after searching a lot. Actually I wanted set of unique IDs to be assigned to a set of dynamically generated CEdit objects, so i was planning to convert from CString to UINT. If i use the following line where iEditId value is 1005(From resource.h)

unsigned int iEditId = IDC_EDIT5;

so next time i can simply increase the ID value by just increment the variable iEditId.

For(iIndex=0;iIndex<=5;iIndex++)
{
pEdit[iIndex]->Create(WS_CHILD | WS_VISIBLE | WS_DLGFRAME | ES_AUTOHSCROLL | WS_TABSTOP, CRect(110, (30 + iSize * 30), 260, (50 + iSize * 30)), this, iEditId + iIndex);
}

This code works fine and returns "12":

CString abc = _T("12/12/2014");   
int date = _ttoi(abc.Left(2));

You surely don't want the integer value of "IDC_EDIT5" but the integer value of the content of the CEdit, don't you?

You are using the tag in the wrong way: IDC_EDIT5 is already defined in one of your header files, something like:

#define IDC_EDIT5 1005

You just use that label as is to get its value, possibly to get an item like:

item = GetDlgItem(hDlg, IDC_EDIT5);
