CListCtrl第一列不能居中的问题(2010-03-09 13:43:00)
摘要：把CListCtrl设置为report风格，但是插入第一列的时候（InsertColumn）的时候会发现文字不能居中，即使使用了LVCFMT_CENTER，但是其他列都可以正常居中。
解决方案：
（1）巧妙解决：插入第一列时宽度设置为0，弃之不用。但是这样有问题，凡是与第一列相关的一些设置将发挥不了作用，例如checkbox和icon。
（2）插入第一列后，改变它的参数：
LVCOLUMN lvc;
lvc.mask =LVCF_FMT;
m_ctrList.GetColumn(0,&lvc);
lvc.fmt&=~LVCFMT_JUSTIFYMASK;
lvc.fmt|=LVCFMT_CENTER;
m_ctrList.SetColumn(0,&lvc);
（3）插入第一列后，将其删除，第二列此时会充当第一列，已经居中了。。。......
CListCtrl OnTimer释疑(2009-10-19 16:45:00)
摘要：自认为对CListCtrl够了解了，但是还不够。昨日碰到一古怪问题，在ClistCtrl中设置一个Timer，但是始终OnTimer只进去一次，很纳闷……
搜索找到了答案：
如果您调用 SetTimer 函数将定期的 WM _ TIMER 消息发送到列表控件时，您可能会发现仅两次调用列表控件的在 WM _ TIMER 消息处理程序 （ OnTimer 函数）。
解决办法：
如果您在 SetTimer 调用中定义计时器 ID，不要 WM _ TIMER 的调用默认处理程序。

CListCtrl滚动条的一些问题搜集(2009-10-16 11:33:00)
摘要：（1）ICON形式中，如果设置属性中对齐方式为LVS_ALIGNTOP,那么当内容容纳不下时，只会出现竖直滚动条（Vertical Scroll)
（2）ICON形式中，如果设置属性中对齐方式为LVS_ALIGNLEFT,那么当内容容纳不下时，只会出现水平滚动条（Vertical Scroll)
（3）Report形式中，当行容纳不下时，出现竖直滚动条；当列容纳不下时，出现水平滚动条
有些时候，如果要强烈禁止出现水平滚动条或者竖直滚动条，那么可以用下面的方法：
void CThumbnailViewList::OnNcCalcSize(BOOL bCalcValidRects, NCCALCSIZE_PARAMS* lpncsp)
{
// TODO: Add your message handler code here and/or call default
ModifyStyle(WS_HSCROLL,0); // 强烈禁止
ShowScrollBar(SB_VERT,1); // 强烈打开
CListCtrl::OnNcCalcSize(bCalcValidRects, lpncsp);
}
例如有人碰到这样的问题：
Hello. I'm working with a CListCtrl on a property sheet, and am having a problem with window sizing and the scroll bars.When my list grows enough to need a vertical scroll, the window space taken by the vertical scroll causes the Control to also create a horizontal scroll. This works fine, but I'm wondering if there is a way to prevent the horizontal scroll from being there. I'......
CGridCtrl在VS2008下的使用问题(2009-09-21 11:30:00)
摘要：VC的控件里面是有GridCtrl的，我为了找到扩展性强的，在codeproject上随便下了个控件玩一玩，但是发现VC下CGridCtrl用的好好的，为什么到了VS2008下就用不了了呢？只要一创建就会报错，到底是哪里出了问题？
查看了资料，看看国外友人的解决办法：
I had the following problem with the 2.26 version.
I build an application with VS2008 and 2.26 gridctrl.
When i wanted to run the program on an XP box, the grid did not display correct.
There was no text, and the columns where very big.
I found in this message area a remark.
So i change CGridDefaultCell::CGridDefaultCell()
changed :
ncm.cbSize = sizeof(NONCLIENTMETRICS);
into :
ncm.cbSize = sizeof(NONCLIENTMETRICS) - sizeof(ncm.iPaddedBorderWidth);
After this things worked.
I think this is a bug.

摘要：
The CListCtrlWithCustomDraw Class
In the OnCustomdraw for CListCtrlWithCustomDraw, I provide a generic handler for custom draw notifications. The bulk of the code is a switch statement on the draw stage we are up to (refer to my previous article). At each of the pre-paint stages, I call virtual functions to get color information, fonts required, and to take over (or augment) the drawing process. I also allow for extra drawing during the post-paint stages.
Let's look at the fleshed out OnCustomdraw function for CListCtrlWithCustomDraw:
void CListCtrlWithCustomDraw::OnCustomdraw(NMHDR* pNMHDR,LRESULT* pResult)
{
// first, lets extract data from
// the message for ease of use later
NMLVCUSTOMDRAW* pNMLVCUSTOMDRAW = (NMLVCUSTOMDRAW*)pNMHDR;
// we'll copy the device context into hdc
// but won't convert it to a pDC* until (and if)
// we need it as this requires ......
