1. Change the iconCopy the icon to the resource file, load the project, and set the ID.In the dialog constructor, modify the icon's ID.Iconcmfc_framedlg::cmfc_framedlg (cwnd* pparent/*=null*/): CDialog (Cmfc_framedlg::idd, pparent) {M_hIcon = AfxGetApp ()->loadicon (idi_mainframe); Change to New icon ID}2. Direct Skin ChangeSkinshape tools SkinH.dll Skinh.; The IB Skinh.she SkinH.h are copied to the project catalog.Add in StdAfx.hdialog box is called before the add3. Change the backgroundFirst

Practical, remember.1, find the appropriate bitmap on the Internet, and add bitmap resources, such as named Idb_back1;2, insert the dialog box, first drag and drop the control;3. Add two variables, bitmap variables and brush variables in the dialog class:CBitmap M_bmback;CBrush M_brback;This is declared as a class member in order to avoid the case where the local variable is destroyed after the function has finished running.4. Load bitmap resources and bit drawing brushes in OnInitDialog:...M_bm

follows: Hbrush Cdlg_signin::onctlcolor (cdc* PDC, cwnd* pwnd, UINT nCtlColor) { Hbrush HBR = Cdialogex::onctlcolor (PDC, pwnd, nCtlColor); Todo:change any attributes to the DC here if (nCtlColor = = ctlcolor_static) { if (pwnd->getdlgctrlid () = = Idc_regard) { Pdc->settextcolor (RGB (255,0,0)); Pdc->setbkcolor (RGB (251, 247, 200));//Set Text background color Pdc->setbkmode (transparent);/Set Background transparent } } Todo:return

For the convenience of illustration, we have built good one dialog-based project named Ttest. dialog box class is Ctestdlg First load a picture with ID IDB_BITMAP2 In TestDlg.h CBrush m_brbk;//defined in public In TestDlg.cpp In the initialization function OnInitDialog (), add: BOOL Ctestdlg::oninitdialog () { CDialog::OnInitDialog (); CBitmap bmp; Bmp. LoadBitmap (IDB_BITMAP2); M_brbk.createpatternbrush (bmp); Bmp. DeleteObject (); return TRUE; Return TRUE unless you set the focus

always try to use it whenever possible.Extract Method(110) to explain the meaning of a piece of code. after all, a temporary variable is meaningful only in the function where it is located, and has many limitations. A function can be useful throughout the entire life of an object and can be used by other objects. but sometimes, when a local variable causesExtract Method(110) when it is difficult, I will useIntroduceExplaining variable(124 ). Practice 1. Declare a final temporary variable and as

, you can separate these code segments into a function. Let's take a look at the following code: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->#region Get Customerpublic void GetCustomer(){// code to get the customer}#endregion#region Save Customerpublic void SaveCustomer(){// code to save the customer}#endregion After it is folded, it becomes as follows: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlig

. Method (1) declare a temporary final variable and assign the calculation result of some actions in the complex expression to it. (2) Replace the "operation result" part of the expression with the temporary variable. (If this part is repeated in the code, you can replace it one by one.) (3) Compile and test. (4) Repeat the above process to process other similar parts. In this example, we start with a simple calculation: // Double price () {// price = basePrice-quantity

1438. Shopaholic ConstraintsTime limit:1 secs, Memory limit:32 MBDescriptionLindsay is a shopaholic. Whenever there is a discount of the kind where can buy three items and only pay for both, she goes completely mad and F Eels a need to buy all items in the store. You had given up on curing she disease, but the try to limit it effect on her wallet. You have realized, the stores coming with these offers is quite selective when it comes to which item

of the operation of a part of the complex expression to be decomposed. (2) Replace the part of "Operation result" in the expression with the temporary variable above. (If this part of the substitution is repeated in the code, it can be replaced one at a time)(3) compile, test. (4) Repeat the above process to deal with other similar parts. Examplelet's start with a simple calculation:Before refactoring double price () {//prices = Baseprice-quantity Discount
