Yet, another method to reposition/resize child windows within their parent framework. Although the subject received a lot of attention, including this web site, I invite you to look at the following method as it presents certain advantages over the others I already know. First of all this is not a library. There is no associated […]

I have an application where I need to work with two CFrameWnd with corresponding documents and views (not MDI, more like SDI * 2). But how can I have two main frame windows? I couldn’t find anything in the docs or here on www.codeguru.com. So I fired up Visual Studio, and started to single-step InitInstance […]

Different views can be seperated into different dlls in an MDI application: Advantages: 1.Depending on the dlls (containing views)registerd in a system the application loads & shows the views. 2.Need not reship the entire application in case of any bugs detected. 3.Can add views at later stage with out modifying the exe. I will try […]

Environment: The code has been tested using VC5 and VC6 under Win98 and WinNT 4.0 and it works fine. What’s this? The CMDIClient is a quite simple CWnd-derived class that allows you to display any bitmap image in MDIClient area or choose any background color. You can load the image from file as well as […]

This article describes a completely object oriented standard file open dialog with preview. No custom hook function, just common MFC message maps. The dialog has a CDibStatic member, which displays the preview image when available. The CDibStatic class encapsulates a static control that displays images and is described in an article in the static controls […]

. Sometimes it is desirable to change the default font specified in dialog templates (usually "MS Sans Serif", 8 pts.) at runtime (dynamically). For example, you may want to increase the font size to make it more readable under higher screen resolutions. MFC library contains a class CDialogTemplate, that serves exactly this purpose, but MS […]

The MFC CFileDialog class only has provision for one default file extension, which is added to a filename if no extension is given. A file export functionality deals with possibly many different file extensions, that have to be added depending on the filetype chosen. The CFileExportDialog class does this. Moreover, when the user selects another […]

Here is my solution for a (little) problem using ODBC and date & time (for VC++ 4.0 & 5.0). If using ODBC & date/time fields in a typical CRecordView, ClassWizard automatically binds a CTime object to the specific recordset. This object has few limits, but the most important is: there is no way to attach […]

In my project, I need to serialize some object into database field with DAO. However, I can not find any support on serializing object into database field. I have to implemented one by myself. In this example, I will show you a class named CByteArrayFile. It is a derive class of CMemFile. With this class, […]

–> Purpose CFloatEdit is a CEdit derived class providing support for editing currency values.. The user specifies the initial value, the number of decimals, the characters for the comma and for the decimal point. The implementation will keep a consistent format during the editing process. Editing features The user types the input digits in the […]

The CPerfStats class gather performance statistics from the Windows 9x Registry. If you want to use CPerfStats class you should create own class derived from CPerfStats. class MyPerfStats : public CPerfStats { public: MyPerfStats(); virtual ~MyPerfStats(); void OnHitCategory( CATEGORY_STRUCT * pCategory ); void OnHitElement( ELEMENT_STRUCT * pElement ); } You should define two function in […]

Environment: The attached demo application has been compiled using VC++ 6 (SP 2) on Win NT (SP 4). It has not been tested on Win 95. This article will discuss a very small utility to check if an EXE file is a console or GUI application. There are no direct API calls, which gives us […]
