(Screen Saver) diffuseGravity
Total Hit (2518) This screen saver simulates 4 particles with gravity, and draws color changing lines between them. Gravity, refresh, and number of color bars are fully configurable, and you end up with some VERY neat pictures. I used the screen saver template at as a starting point. ....Read More
Animated form icons
Total Hit (3631) You can add a professional touch to your apps by showing an animated icon when the main form is minimized. To achieve this effect, prepare an array of Image controls, each one containing the icons that make up the animation, then add a Timer control, with the Enabled property set to True and the Int ....Read More
Build a simple browser for icons
Total Hit (2645) Winodws uses a special browser to show all icons contained in a file and offers the end user the possibility to choose an icon from it. You can add this functionallity to your applications through an undocumented API function, SHChangeIconDialog. Its Declare is: «Code LangId=1» Declare Function ....Read More
Convert a color value to a gray scale
Total Hit (2849) When you have a 32-bit color value, you can convert it to a grey-scale - that is, you can determine how it would appear on a monochromatic display (more or less) using the following function: «Code LangId=1» Function GetGreyScale(ByVal lColor As Long) lColor = 0.33 * (lColor Mod 256) + 0.59 ....Read More
Copy the contents of the screen or the active window
Total Hit (4823) The standard way to copy the contents of the screen or a window to a picture box requires you to use a lot of API functions, such as BitBlt. A simpler approach is possible, though: you just have to simulate the typing of the Print Screen key (or Alt+Print Screen if you want to copy the contents of t ....Read More
Display an animated GIF using the WebBrowser control
Total Hit (3736) The standard PictureBox control doesn't support the Animated GIF graphic format. However, you can display these images by using a WebBrowser control: «Code LangId=1» WebBrowser1.Navigate "c:\Images\Animated.Gif" «/Code» The only problem of this technique is that the WebBrowser control also di ....Read More
Extract Red,Green,Blue components of a color
Total Hit (2586) If you have a 32-bit color value in RGB format, you can extract its Red, Green and Blue components using the following routines: «Code LangId=1» Function GetRed(ByVal lColor As Long) As Long GetRed = lColor Mod 256 End Function Function GetGreen(ByVal lColor As Long) As Long GetGre ....Read More
Extract RGB components from a Long value
Total Hit (2676) You can extract RGB values out of a 32-bit color value by using the integer division and the MOD operators, but there is a much more effective way, based on the LSet. You can convert from a long to rgb bytes and vice versa with the following code: «Code LangId=1» Private Type RGBWrapper Red ....Read More
Getting a pixel color
Total Hit (3545) The Point method returns the color value of a given pixel, but is rather slow because it has to convert its argument from twips (or whatever ScaleMode is currently active) to pixels, and also because its argument are treated as Single quantities, and must therefore converted. When you have to retrie ....Read More
Retrieving Bitmap properties
Total Hit (3700) The Picture box control does not directly expose any property that returns information on the bitmap currently loaded. You can retrieve this information by calling the GetObject API function, passing it the handle of the bitmap. This value is the Handle property of the IPictureDisp object (which is ....Read More
Setting a pixel color
Total Hit (3203) The PSet method is much slower than it should actually be, and in most cases you will find it convenient to substitute it with direct calls to the SetPixel API functions. This function is about twelve times faster than the VB's method, at least when you can set the form's ScaleMode to Pixels, for mo ....Read More
