Did you convert as shown in this article[^]?
int z = 44;
Object^ o = z;
int y = *reinterpret_cast<int^>(o);

I will try that. Thanks for your answers and help!
I used a code which shown in one of the articles from this forum which helps to control 4 Progressbars in a Form from 4 Threads.
See: http://www.codeproject.com/KB/mcpp/managedsafethreads.aspx[^]
It works fine, since the delegate function seems to be recalled until the InvokeRequired-property is false. in this case the progressbars can be controlled directly in the thread by "form->progressBar1->PerformStep();"
In my case I want to get the Value (Position) of the trackBar-component. So if the delegate function is called 2 times we have a recursive calling of the same function. I assumed that the return value is then overwritten by the previous call of my function "Get_TrackBar1_Value(object)".
I will let you know about the result.

Everything is working fine...
Thanks again!

Hello,
I'm writing an add-in in for Visual Studio in C++ and need to get access to the DebuggerEvents in Visual Studio. See here for a description: http://msdn.microsoft.com/de-de/libr...s_members.aspx . Especially I need to receive events from "OnEnterBreakMode". Unfortunately all these methods are marked as "internal use only". There is also no definition in the headers.
The interesting part is, that I can access and get notification from all these events within C# without any problem. (C# reference on DebuggerEvents: http://msdn.microsoft.com/de-de/libr...us,VS.71).aspx) So how can I manage to access the DebuggerEvents in C++?
thanks for your help in advance!

hi,
i am trying to transparent the dialog with color using this code. I included the windows.h and winuser.h
<pre>
SetLayeredWindowAttributes(GetSafeHwnd(),RGB(10,34,56),10,(LWA_COLORKEY|LWA_ALPHA));
</pre>
But it gives following error.
\\ITD254\VCC\Notes\NotesDlg.cpp(168) : error C2065: 'SetLayeredWindowAttributes' : undeclared identifier
\\ITD254\VCC\Notes\NotesDlg.cpp(168) : error C2065: 'LWA_COLORKEY' : undeclared identifier
\\ITD254\VCC\Notes\NotesDlg.cpp(168) : error C2065: 'LWA_ALPHA' : undeclared identifier
what i have to do

Which version of visual studio are you using? Have you set win version (_WIN32_WINNT ) to 0x0501 ?
|
|
|
|
|
vc 6.0 and i tried #define WINVER 0x0500
Os- winxp
|
|
|
|
|
i opened the winuser.h and found that SetLayeredWindowAttributes() is not available.
for that i downloaded winuser.h, which has SetLayeredWindowAttributes() and replaced original but now compiler tells so many errors in winuser.h
any solution

The SetLayeredWindowAttributes() will not be existing in the header files that comes with visual studio 6. So either you can download the platform SDK from here[^] and integrate it with VC6
or
Call the SetLayeredWindowAttributes() dynamically, using the LoadLibrary() and GetProcAddress() functions. The SetLayeredWindowAttributes exists in user32.dll dll and the value of LWA_COLORKEY and LWA_ALPHA are...
#define LWA_COLORKEY 0x00000001
#define LWA_ALPHA 0x00000002
|
|
|
|

i got user32.dll
but i have some doubt.
1. can i load that dll from my project folder(because i download that from web, my don't doesn't)
2. if load that file in dynamic mode, but before that compiler gives error(for setlayeredwondowattributes()).
Frankly saying i'm new to VC so please guide me

No you dont have to download it from net. That dll comes with the installation of OS. it exists in the "c:\WINDOWS\system32\user32.dll"
ganesh.dp wrote: 2. if load that file in dynamic mode, but before that compiler gives error(for setlayeredwondowattributes()).
ok. This is how to call that function dynamically.
#define LWA_COLORKEY 0x00000001
#define LWA_ALPHA 0x00000002
typedef BOOL (WINAPI *pSetLayeredWindowAttributes)( HWND hwnd, COLORREF crKey, BYTE bAlpha, DWORD dwFlags );
HMODULE hUser32 = LoadLibrary( _T("User32.dll"));
pSetLayeredWindowAttributes fnSetLayeredWindowAttributes = (pSetLayeredWindowAttributes)GetProcAddress( hUser32, "SetLayeredWindowAttributes");
if( 0 == fnSetLayeredWindowAttributes )
{
AfxMessageBox( _T("Failed to load SetLayeredWindowAttributes function"));
}
else
{
fnSetLayeredWindowAttributes( m_hWnd, 0, 100, LWA_ALPHA );
}
FreeLibrary( hUser32 );

Have you set WS_EX_LAYERED style? This style is necessary for the SetLayeredWindowAttributes() function to work.

i got it...
thanx a lot...

When I Compile my project I got this Warning
"warning C4819: The file contains a character that cannot be represented in the current code page (874). Save the file in Unicode format to prevent data loss"
I want to solve this problem, Please advise
How can I save the file in Unicode format
|
|
|
|
|
Does this page[^] help? It's talking about how to save files with different encodings in VS2005, using the File Save dialog.
|
|
|
|
|
VS editor now supports Unicode characters as well (for strings to be used in the code). If you don't know what Unicode is, I suggest you to please read up on that.
