“遇到不正当的论点"； [英] "Encountered an improper argument"

问题描述

这可能是什么问题?工作正常，然后...不正确的参数.

它与删除数组中的记录有关吗?

What could be wrong with this? It was working fine and then...Improper Argument.

Could it have something to do with deleting records from the array?

for(int i = 0; i < FirstName.GetCount(); i++)
    {
        nItem = m_ListCtrl.InsertItem(0, FirstName[i] + L" " + LastName[i]);
        for(int j = 0; j < 8; j++)
        {
            if(Item[numItems].IsEmpty() == FALSE)
            {
            nItem = m_ListCtrl.InsertItem(1, L"");
            m_ListCtrl.SetItemText(nItem, 1, Item[numItems]);
            m_ListCtrl.SetItemText(nItem, 2, Quantity[numItems]);
            m_ListCtrl.SetItemText(nItem, 3, Cost[numItems]);
            m_ListCtrl.SetItemText(nItem, 4, Price[numItems]);
            m_ListCtrl.SetItemText(nItem, 5, Profits[numItems]);
            }
            numItems++;
        }
    }

推荐答案

您最好的朋友就是大多数情况下的调试器.但是仅仅看代码我会怀疑

Your best friend is as in most cases your debugger. But from just looking at the code I would suspect that

nItem = m_ListCtrl.InsertItem(0, FirstName[i] + L" " + LastName[i]);

可能由于失败(无论出于何种原因)而返回-1，并且以下

might return -1 when not successful (for whatever reason) and the following

m_ListCtrl.SetItemText(nItem, 1, Item[numItems]);

将失败，因为nItem为-1.

will fail because nItem is -1.

我试图读取超出数组存储数据量的数组.这是我为解决此问题所做的事情:

I was trying to read my arrays beyond the amount of data that the arrays had stored. This is what I did to fix this issue:

s7 = (((_wtof(myData[nPos].m_sPrice7) / _wtof(myData[nPos].m_sQty7)) - _wtof(myData[nPos].m_sCost7)) * _wtof(myData[nPos].m_sQty7));
            t7.Format(L"%.2f", s7);
            if(s7 > 0)
                dlg.Profits.Add(t7);
            else
                dlg.Profits.Add(L"0");

我添加了else语句来解决我的问题，它又可以正常工作.

I added the else statement to fix my problem, it works fine again.
