Demoversion download
Fully working testing version of the dll (u32) library available,
examples in programming languages listed below are enclosed (the
demo version is fully working but the library will show a dialogue
window).
Description
The library allows you to adjust shapes of windows and to work with
translucence and transparency of the windows. Most of the functions
can be combined with one another so that interesting effects in
the windows can appear. The library works in Windows. Some functions
only work in Windows 2000 and XP.
Library is compatible with
Authorware 3, 3.5, 4, 5, 6, 6.5, 7
Delphi 2, 3, 4, 5, 6, 7
Toolbook 6, 6.5, 7, 7.1, 7.2, 8, 8.5
Visual Basic, language C and others
.NET framework

List of functions
Description of functions
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_RegWindow(code:string)
We must call this function before we use the dmm_volume.dll
(dmm_volume.u32) library for the first time. If you do not insert
the correct registration number a note saying this is a demo version
will appear after you start the application.
Parametres
The type of code is string (lpcstr), for the demo version code="demo".
For the commercial version the chain is unique.
Example
dmm_RegWindow("demo")
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_BitmapRgn(handle:word,
file:string)
This function allows you to create applications, whose window
is not rectangular but rounded or differently irregular. The function
reads the mask from an external bmp folder and reduces the window
depending on it. What is black is reduced so it is not visible.
What is white will stay visible. The window is reduced including
all the driving elements. It is necessary to know it.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
The type of file is string and we place here the bmp folder, which
the window should be in accordance with (including the path)
Example
dmm_BitmapRgn(handle, "c:\euro.bmp")
Note
It is possible to prepare more than one mask and then to change
these masks during the application.
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_RoundRectRgn(handle:word,
widthEllipse:word, heightEllipse:word)
This function allows you to create applications whose windows
are rounded. The window size will not change only the corners will
become rounded.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
WidthEllipse is in pixels and it determines a value of camber in
horizontal axis. HeightEllipse is also in pixels but it determines
a value of camber in vertical axis.
Example
dmm_RoundRectRgn(handle,20,25)
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_RectRgn(handle:word,
left:word, top:word, width:word, height:word)
This function allows you to create applications whose windows
are rectangular.Extents of the window are defined by the function
parametres. This function can cancel the adjustment of dmm_BitmapRgn,
dmm_RoundRectRgn, if you place the original window extents.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
Left is in pixels and it determines the x-coordinate of the upper-left
window corner. Top is in pixels too and it determines the y-coordinate
of the upper-left window corner. Width is size of the window in
pixels and so is Height.
Example
dmm_RectRgn(handle,20,25,200,500)
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_AlphaBlendWindow(handle:word,
opacity:word)
This function allows you to constitute transparency for alfa
windows. It only works in Win NT, 2000, XP.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
The type of opacity is word and the value is from 0 to 100 (it is
the value of opacity).
100-opaque window, 0- transparent window.
Example
dmm_AlphaBlendWindow(handle,25)
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_TransparentColorWindow(handle:word,
r:word, g:word, b:word)
This function allows you to create translucent windows. You
adjust translucence in the colour system RGB. It only works in Win
NT, 2000, XP.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
The type of R, G, B is word and it is adjustment of colour in the
RGB system. The parametres can be between 0 and 25.
Example
dmm_TransparentColorWindow(handle,255,0,0) causes that translucent
colour will be the red one in the window.
-----------------------------------------------------------------------------------------------------------------------------------------------------------
void=dmm_FadeFromToWindow(handle:word,
opacity_1:word, opacity_2: word, time:word, period:word)
This function allows you to animate transparency of windows.
The dmm_FadeFromToWindow function animates transparency of windows
in interval opacity_1 and opacity_2. If the opacity_1 is less than
the opacity_2, transparency decreases. In the other case it increases.
It only works in Win NT, 2000, XP.
Parametres
The type of handle is word and it is handle of the the window which
we want to be changed.
The type of opacity _1 is word and its value ranges from 0 to 100.
It shows level of the original transparency.
The type of opacity _2 is word and its value ranges from 0 to 100.
It shows level of the final transparency.
100-opaque window, 0- transparent window.
The type of time is word and it adjusts time which the whole animation
will take (in milliseconds).
The type of period is word and it is time in which the window will
begin to change (time of one section of the animation). The period
can range from 5ms to 5000ms.
If you choose, for instance, time=5000ms and period=20ms, then the
window will be repainted 50 times during the whole animation. We
must realise that during the animation processor must recount the
whole application window and it means it is extremely busy. That
is why we must choose the period intelligently. With some computers
it is possible that the animation will take longer than we have
adjusted. It is because the processor is busy.
Example
dmm_FadeFromToWindow(handle,100,25,1000,25);
dmm_FadeFromToWindow(handle,25,100,2000,50);
This will make the window disappear fluently and display again.
-----------------------------------------------------------------------------------------------------------------------------------------------------------
Important
Most of the functions can be combined with one another so that
you can reach very interesting shapes and effects of the windows.
