A	Custom Draw With List View and Tree View Controls Most common controls can be handled in essentially the same way. However, the list view and tree view controls have some features that require a somewhat different approach to custom draw. For Version 5.0 of the common controls, these two controls may display clipped text if you change the font by returning CDRF_NEWFONT. This behavior is necessary for backward compatibility with earlier versions of the common controls. If you want to change the font of a list view or tree view control, you will get better results if you send a CCM_SETVERSION message with the wParam value set to 5 before adding any items to the control. Custom Draw With List View Controls Because list view controls have subitems and multiple display modes, you will need to handle the NM_CUSTOMDRAW notification somewhat differently than for the other common controls. For report mode: The first NM_CUSTOMDRAW notification will have the dwDrawStage member of the associated NMCUSTOMDRAW structure set to CDDS_PREPAINT. Return CDRF_NOTIFYITEMDRAW. You will then receive an NM_CUSTOMDRAW notification with dwDrawStage set to CDDS_ITEMPREPAINT. If you specify new fonts or colors and return CDRF_NEWFONT, all subitems of the item will be changed. If you want instead to handle each subitem separately, return CDRF_NOTIFYSUBITEMDRAW. If you returned CDRF_NOTIFYITEMDRAW in the previous step, you will then receive an NM_CUSTOMDRAW notification for each subitem with dwDrawStage set to CDDS_SUBITEM | CDDS_PREPAINT. To change the font or color for that subitem, specify a new font or color and return CDRF_NEWFONT. For the large icon, small icon, and list modes: The first NM_CUSTOMDRAW notification will have the dwDrawStage member of the associated NMCUSTOMDRAW structure set to CDDS_PREPAINT. Return CDRF_NOTIFYITEMDRAW. You will then receive an NM_CUSTOMDRAW notification with dwDrawStage set to CDDS_ITEMPREPAINT. You can change the fonts or colors of an item by specifying new fonts and colors and returning CDRF_NEWFONT. Because these modes do not have subitems, you will not receive any additional NM_CUSTOMDRAW notifications. An example of a list view NM_CUSTOMDRAW notification handler is given in the next section. Using Custom Draw The following code fragment is a portion of a WM_NOTIFY handler that illustrates how to handle custom draw notifications sent to a list view control: LPNMLISTVIEW pnm    = (LPNMLISTVIEW)lParam; switch (pnm->hdr.code){ ... case NM_CUSTOMDRAW:     LPNMLVCUSTOMDRAW lplvcd = (LPNMLVCUSTOMDRAW)lParam;     switch(lplvcd->nmcd.dwDrawStage) {     case CDDS_PREPAINT :         return CDRF_NOTIFYITEMDRAW;        case CDDS_ITEMPREPAINT:         SelectObject(lplvcd->nmcd.hdc,                      GetFontForItem(lplvcd->nmcd.dwItemSpec,                                     lplvcd->nmcd.lItemlParam) );         lplvcd->clrText = GetColorForItem(lplvcd->nmcd.dwItemSpec,                                           lplvcd->nmcd.lItemlParam);         lplvcd->clrTextBk = GetBkColorForItem(lplvcd->nmcd.dwItemSpec,                                               lplvcd->nmcd.lItemlParam); /* At this point, you can change the background colors for the item and any subitems and return CDRF_NEWFONT. If the list view control is in report mode, you can simply return CDRF_NOTIFYSUBITEMREDRAW to customize the item's subitems individually */         ...         return CDRF_NEWFONT;  // or return CDRF_NOTIFYSUBITEMREDRAW;       case CDDS_SUBITEM | CDDS_ITEMPREPAINT:         SelectObject(lplvcd->nmcd.hdc,                      GetFontForSubItem(lplvcd->nmcd.dwItemSpec,                                        lplvcd->nmcd.lItemlParam,                                        lplvcd->iSubItem));         lplvcd->clrText = GetColorForSubItem(lplvcd->nmcd.dwItemSpec,                                              lplvcd->nmcd.lItemlParam,                                              lplvcd->iSubItem));         lplvcd->clrTextBk = GetBkColorForSubItem(lplvcd->nmcd.dwItemSpec,                                                  lplvcd->nmcd.lItemlParam,                                                  lplvcd->iSubItem)); /* This notification is received only if you are in report mode and returned CDRF_NOTIFYSUBITEMREDRAW in the previous step. At this point, you can change the background colors for the subitem and return CDRF_NEWFONT.*/         ...         return CDRF_NEWFONT;        } ... } The first NM_CUSTOMDRAW notification has the dwDrawStage member of the NMCUSTOMDRAW structure set to CDDS_PREPAINT. The handler returns CDRF_NOTIFYITEMDRAW to indicate that it wishes to modify one or more items individually. The control then sends an NM_CUSTOMDRAW notification with dwDrawStage set to CDDS_PREPAINT for each item. The handler returns CDRF_NOTIFYITEMDRAW to indicate that it wishes to modify the item. If CDRF_NOTIFYITEMDRAW was returned in the previous step, the next NM_CUSTOMDRAW notification has dwDrawStage set to CDDS_ITEMPREPAINT. The handler gets the current color and font values. At this point, you can specify new values for small icon, large icon, and list modes. If the control is in report mode, you can also specify new values that will apply to all subitems of the item. If you have changed anything, return CDRF_NEWFONT. If the control is in report mode and you want to handle the subitems individually, return CDRF_NOTIFYSUBITEMREDRAW. The final notification is only sent if the control is in report mode and you returned CDRF_NOTIFYSUBITEMREDRAW in the previous step. The procedure for changing fonts and colors is the same as that step, but it only applies to a single subitem. Return CDRF_NEWFONT to notify the control if the color or font was changed.
Q	请教：CListCtrl不能显示中文？？？？
T	我在ListCtrl中加入了一些英文的字符串（使用InsertColumn、InsertItem、SetItemText）一切显示正常，可是我把其中的串换成中文时显示出来的都是乱码，注：我用AppWizard建的是一个英文的工程，里面的资源也都设的是中文的。 请问这是怎么回事？难道CListCtrl不支持中文？？应该如何解决？谢谢！

A	LVN_ITEMCHANGING Notifies a list-view control's parent window that an item is changing. This notification message is sent in the form of a WM_NOTIFY message. LVN_ITEMCHANGING     pnmv = (LPNMLISTVIEW) lParam; Parameters pnmv Address of an NMLISTVIEW structure that identifies the item and specifies which of its attributes are changing. Return Values Returns FALSE to prevent the change, or TRUE to allow the change. 你在PRESTRANSLATEMESSAGE里面截获,这样LVN_ITEMCHANGING 没有被处理,系统执行默认动作 你应该在LVN_ITEMCHANGING 中设置返回值为FALSE
