Hi,
Would you tell me what callback function is used? Why we need it? I
searched the web. But most webpages only mention that how to use it but
not why to use it.
Best wishes,
Peng

I have a Win32 DLL that has a standard _stdcall (WINAPI) exports. I am able
to call these fine from C#. One call in particular however has a callback to
a CDECL function. How would I set that up? Following is the specific.
Win32 DLL Declaration for function in MyDLL.dll
extern "C" int WINAPI SpecialTimerFunction(int Val, int (*Callback)(int
InVal))
C# Declaration
public class MyClass

I have a windows application that is accessing unmanaged
code and providing a callback function that will create
events at unknown time spans. When the EventHandler
(callback function) fires it causes my program to crash or
freeze, or do strange stuff. When I remove this callback
function it works great. Problem is I need this callback
function to implement my state machine for the program so
I think I need to encapsulate this callback...

Hi,
I have just now installed VS.NET on my system and created basic .aspx
files using
<asp:label id="Message1" font-size="16" font-bold="true"
forecolor="red" runat=server>Test</asp:label>
tags to test the pages.
When I save and run the pages, I am able to see the text but not the
font or color which i have specified in ASP.Label. If I view source
the page I see the tags correctly.

I need to do the exactly same thing in VB.NET.
Load a unmanaged C DLL dynamically and then call a function in which I pass
the callback function as an argument. My C function being called callback as
type _cdecl.
Does anybody have any ideas?

I have processing code (I'll call it the "model") written in native
unmanaged pure C++, and I have put a GUI on top of it written using
Windows Forms (.NET 1.1). The GUI is used to set the parameters for the
model, and once all parameters are set and checked to be valid, I run
the model. The model takes a long time to run, so I decided to run it
in a background thread, and have it notify the GUI when it is complete.
The GUI will then...

Hi,
I need some help regarding callback function written in c# and called from unmanaged c code. (c dll).
The problem is that the callback function crashs after the first call with a memory access exception. I tried to protect the callback function to be handle by the GC but it doesn't work. What could I do to fix that problem??
Thanks, Michibeck

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
