 Download Source Code and Example This custom control displays a left scrolling spike with range configurable by calling SetRange(0,100), the first parameter is the min(bottom) value and the second parameter is max(top) value. The control is designed to work just like the progress control but with a twist. Every SetPos() will shows a spike and […]

. Sometimes it can be handy to exclude a set of options based on the users choice. For instance if the user do not want to save a log file, then it should be signalled, to the user, which options are relevant. fig.1 The checkframe control are disabled, and so is its the contained controls. […]

Go into ‘Class Wizard’ and add a control name to your […]

The zip file contains a set of classes that allow the use of many of the new IE4 controls in any C++ program. The code on these classes is based on the VC++ Technology Preview, the only thing needed from the Technology Preview is the commctrl.h file. Included are classes for: ComboBoxEx (like normal combo […]

  This control has the following features: A 3D vector MFC control derived from CButton. Real-time light rendering on a 3D ball. Variable ball radius and position. Supports bitmap background (tiled). Supports vertical gradient color background (from color to color, as visiable in screen capture above). Variable ball color (diffuse), light color and ambient color. […]

If you want to paint inside client area (a logo in the middle or even all background), this class should fit your needs. If you want to paint a logo, it will redraw only the rectangle, which cover the invalid rectangle, the old bitmap area, and the new logo area. Because I used the memory […]

I wanted to paint bitmaps on forms, like Access does. So I wrote some code for that: First, add in your derived CFormView two members: CPalette m_palette; CBitmap m_bitmap; Add the following functions to your derived class: OnDraw overrides the base class’ function, and OnCtlColor is a handler for WM_CTLCOLOR message. Call in OnInitialUpdate the […]

The function BitmapToRegion() below, as its name implies, create a region from a bitmap. It scans the bitmap content (using a memory DC associated to a 32 bit DIB section), find continguous lines of non "transparent" pixels, add these lines to a RGNDATA structure, and finally, create the resulting region by calling ExtCreateRgn(). The function […]

This is best explained with pictures. The left most image is some text and a simple shape. The image in the middle is the bitmap on which we want to emboss the first image. The result is shown in the third image. So, this topic will basically give you the code to achieve this result. […]

We have already covered how to fade in a bitmap starting from a single color or how to fade out a bitmap to a single color. The code given here extends the idea a little bit further. It either starts with a grayscale image of the bitmap and turns into a full color image or […]
