MFC错误:CListCtrl问题 [英] MFC Error: Problem with CListCtrl

问题描述

大家好，

我正在MFC中开发基于对话框的应用程序，并且具有带有复选框的CListCtrl.代码如下:

Hi everyone there,

I am developing a dialog based application in MFC and I have a CListCtrl with checkboxes. Code is as follows:

CListCtrl m_gridOutput;m_gridOutput.SetExtendedStyle(m_gridCtrlEx.GetExtendedStyle() | LVS_EX_CHECKBOXES);

我可以跟踪ListControl中的更改，但是现在我试图更改项目复选框的状态.不幸的是，当我尝试使用以下代码时，我遇到断言错误.

I can track the changes in the ListControl but now I am trying to change the status of the Checkbox of an item. Unfortunately I am getting Assertion errors, when I try to use the following piece of code.

m_gridOutput.SetItem(1,0,LVIF_STATE,NULL,0,dwFlags,dwFlags,0);
(or)
ListView_SetItemState(m_gridOutput.GetSafeHwnd(),VarId,INDEXTOSTATEIMAGEMASK((fCheck)+ 1), LVIS_STATEIMAGEMASK);
(or)
ListView_SetCheckState((m_gridOutput.GetSafeHwnd(),Id,TRUE);

我想在这里再添加一件事.如果在OnInitDialog()中使用SetCheck (or) ListView_SetCheckState，它可以正常工作.但是，如果我尝试在单独的函数中使用它，则会产生断言错误.如何处理?.

任何帮助将不胜感激.

I want to add one more thing here. If I use SetCheck (or) ListView_SetCheckState in OnInitDialog(), it works fine. But if I try to use it in a seperate function, it gives assertion error. How to handle this?.

Any help is greatly appreciated.

Shiva
