ok.
so it need to be loaded first. and if the DLL doesn't exist in the system it will not run to begin with. so the API is useless here.

loadlibrary and all that u mean?
yeah, u can do that, its usually used to run a dll that is not registered.
and what about getmodule API?

and u compile and run the exe, not run it from the IDE?
and is the code in freebasic really the same?

also important to use "byval" in freebasic as well and not "byref"

u dont need more performance wise,
its just checkboard we are dealing with.
sure u can create a memorydc, and create a "screen*screen" sized checkboard
after that just use bitblt to render the...

yeah. exactly, no need for it. and with autoredraw = false it will render even faster.

but with false, u need to move the "resize" to Form_Paint() instead.

edit:
really? well it works at least...

yeah, using a picturebox to "store" the color (u can even use setpixel) and after that stretchbitblt,
hard to make it smaller. also stretchbitblt is quite fast as well.
even GdiAlphaBlend is...

the pictureboxes are only use for color. those are invisible.
this so stretchbitblt can copy and stretch it to whatever rectangle.
of course u could create a memorydc and apply fillrect with a...

use stretchbitblt
and a couple of pictureboxes with the color u want to use.

some machine will not run without installing Visual Basic 6.0 Runtime (vbrun6)
they will tell theres a missing DLL.

but a empty project, should run.
its some of the components that can cause...

yeah exactly. this is just the basics. u need to implement what u want to react with the wheel.

remember that subclassing can crash your application.
so ALWAYS save your project before u run it.

did u try subclassing?
thats what most people are using.

very easy.
create a project, add this in Form_Load

StartClassing Me.hWnd

add a module:

well, the msgbox are added to find the crash.

so

1
2
3
4 crash
5

yeah. its interesting how things changes with OS.
new bugs appears, or reveals.
even so they have done a great job making VB6 applications survive that long and still works for the most part.

u r not using CreateCompatibleDC alone

hDC = CreateCompatibleDC(0)

the hDC is a clone of "0" that is the desktop hDC, so using GetDeviceCaps will point...

the "best" way seems to be to add in all your fuctions:

Sub/Function BlaBla()
On Error Goto TErr

Exit Sub/Function

End Sub/Function

my game is mostly modules. I have 2 classes. one is the direct2d engine and one is the directsound8 engine.

hm.
usually a crash without knowing where is if u use a class.
so it will only tell that the call crashed but not where inside the class
I would change the class into a module if possible.

as I wrote, u can use subclassing, here an example:

in a module


Option Explicit

Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex...

U will need to add on error everywhere.
I think it’s possible to subclass. Or u need to check err.number each function

I tried with that, something similar using GetDeviceCaps,
but if I remember correctly it didnt work
if showed differently if compiled or in IDE. Im in windows 7.
but I will give it a try tomorrow...

yeah, its a mess.
not sure how to get it I have even tried to get from Direct2d, but its not correct.
instead my solution was to just "skip it" and use the screen resolution since that gave me the...

I use WIC+D2D for just my needs. I have actually not looked deeper.

the problem is to get the "correct" DPI value.
it depends on many factors, is the application aware or not (manifest or API), are we in 7-8-10?
but if you have a good function, like

its used to load pictures and create direct2d bitmaps.
of course theres a lot more u can use it for....

u can use direct2d/wic, no 3rd party dll needed.
so again. u can replace if u want. not sure why.
and to draw and rotate oval shapes, should not be a problem with direct2d.

I think its mostly because theres tons of sources about it, not because u can't use Direct2D.

I think thats a good way of coding and bundle all together.

I don't agree with wqweto. u should "always" destroy a class or any GDI objects.

LaVolpe used 1 token for all his classes.

you can use your approach, but that doesn't mean you can not do differently.

do u really not understanding DPI dilettante? I thought u where.
but u fail miserably here.

when u "INCREASE" DPI you also "DECREASE" resolution.
meaning "EVERYTHING" gets "BIGGER".

its not manually. u can not drag and move. like most windows.
the other is pre-defined sizes. so its not manually resizing but change size.

they can not "manually resize". they can only use the settings to change the size. but the size is dynamic, so it will adjust depending on screen. a big screen will give u bigger factors.

yeah. I agree with that. null pointer are used. I even use it. and I myself changed a few to "any" but that mostly because there was a need for it.

why would u pass a null pointer when the whole reason u call this API is to retrieve MONITORINFO/EX?
