vc++,MFC,组合框控件设置时0xC0000005: 读取位置 0x00000020 时发生访问冲突

 

511.exe 中的 0x78bb5dec (mfc90ud.dll) 处未处理的异常: 0xC0000005: 读取位置 0x00000020 时发生访问冲突

 

_AFXWIN_INLINE int CComboBox::SetCurSel(int nSelect)     { ASSERT(::IsWindow(m_hWnd)); return (int)::SendMessage(m_hWnd, CB_SETCURSEL, nSelect, 0); } //IA64: Assuming retval of CB_GETEDITSEL won't be expanded

 

程序在resource.h中，没有找到对应的控件ID编号，就报错了。

//IDC_COMBO_2D_BARCODE2 1082  //IDC_COMBO_2D_BARCODE5    1338

循环中，当i=3,是，想设置IDC_COMBO_2D_BARCODE2   +3  =  IDC_COMBO_2D_BARCODE5

1082+3=1085

理论：

IDC_COMBO_2D_BARCODE5 控件ID位：1085

但实际

在resource.h中 IDC_COMBO_2D_BARCODE5=1338，所以报错。

 

 

 

 

int nr = print_chars_all.print_chars_property[itemNo].link_2d_chars.nr_of_links;
		for (int i = 0; i < 4; i++)
		{
			if(i < nr)
			{
				temp = print_chars_all.print_chars_property[itemNo].link_2d_chars.link_chars[i];
				SetDlgItemText(IDC_EDIT_2D_LINK_SYMBOL1+i, temp);
                   //IDC_COMBO_2D_BARCODE2 1082
				//IDC_COMBO_2D_BARCODE5    1338
				/*if(i==3)
				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE5, print_chars_all.print_chars_property[itemNo].link_2d_chars.print_chars_keyword[i+1]);
				}
				else*/
				{
                  SetComboBoxSel(IDC_COMBO_2D_BARCODE2+i, print_chars_all.print_chars_property[itemNo].link_2d_chars.print_chars_keyword[i+1]);
				}
				
			}
			else
			{
				/*if(i==3)
				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE5, 0);
				}
				else*/

				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE2+i, 0);
				}
			}

改成这样，就不会报错了。

int nr = print_chars_all.print_chars_property[itemNo].link_2d_chars.nr_of_links;
		for (int i = 0; i < 4; i++)
		{
			if(i < nr)
			{
				temp = print_chars_all.print_chars_property[itemNo].link_2d_chars.link_chars[i];
				SetDlgItemText(IDC_EDIT_2D_LINK_SYMBOL1+i, temp);
                   //IDC_COMBO_2D_BARCODE2 1082
				//IDC_COMBO_2D_BARCODE2    1338
				if(i==3)
				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE5, print_chars_all.print_chars_property[itemNo].link_2d_chars.print_chars_keyword[i+1]);
				}
				else
				{
                  SetComboBoxSel(IDC_COMBO_2D_BARCODE2+i, print_chars_all.print_chars_property[itemNo].link_2d_chars.print_chars_keyword[i+1]);
				}
				
			}
			else
			{
				if(i==3)
				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE5, 0);
				}
				else

				{
					SetComboBoxSel(IDC_COMBO_2D_BARCODE2+i, 0);
				}
			}
		}
