I have a project which loads couple dlls. By Default, it loads from Windows/System32. I was trying to debug the problem with it's crash. And I would like to build a debug version with all the dll files that could run from the same directory as my main executable. However, some dll were loaded from the debug directory only which means if I delete the dlls from the debug directory of my project then it won't run. Even if I put the dlls in the same directory as the main exe or the windows/system32.
What kind of setting in my project could lead the loading of a dll from debug directory?
Or how could I set the dll loading always look for current directory and then windows/system32?
Thanks

Use explicit linking (LoadLibrary) instead of implicit. Giving path of dll you want.

im trying to create a thread to listen on a port for incomming data but i keep getting errors
HANDLE Handle_Of_listener = 0;
Handle_Of_listener = CreateThread( NULL, 0, listener, &s, 0, NULL);
when i try to compile that it returns:
.\main.cpp(34) : error C3867: 'Messenger::listener': function call missing argument list; use '&Messenger::listener' to create a pointer to member
soo i do what it says and create a pointer to my listener() function
Handle_Of_listener = CreateThread( NULL, 0, &listener, &s, 0, NULL);
errors:
.\main.cpp(34) : error C2276: '&' : illegal operation on bound member function expression
i mean come on i do what it tells me to the says it's illegal!!

The problem is not in the CreateThread() call.
It's in the declaration of Messenger::listener
How are you declaring that function in your Messenger class?
EDIT: It should be
static DWORD WINAPI listener(LPVOID lpParam);

i am now getting this error when i declared it as
static DWORD WINAPI listener(SOCKET s)
.\main.cpp(34) : error C2664: 'CreateThread' : cannot convert parameter 3 from 'DWORD (__clrcall *)(SOCKET)' to 'LPTHREAD_START_ROUTINE'

You want to pass the SOCKET to the thread procedure correct?
Declare your class-member thread procedure as
static DWORD WINAPI listener(LPVOID lpParam);
Write the function something like this:
DWORD WINAPI myclass::listener(LPVOID lpParam)
{
SOCKET s = (SOCKET)lpParam;
... do stuff with the socket...
return 0;
}
Create the thread something like:
HANDLE Handle_Of_listener_thread = 0;
Handle_Of_listener_thread = CreateThread( NULL, 0, listener, (LPVOID)s, 0, NULL);
Better?

I have a Image on my dialog this picture is on the WM_ERASEBKGND and its work fine but I have a problem
when I move my program or if I move a program on my program then Mem Usage of my program increase How can I solve this problem. And I have another question
if I use of a code like this on WM_PAINT It increase PF Usage and Mem Usage of my program or no
<br />
void CMyPicture::OnPaint()<br />
{<br />
CPaintDC dc(this); <br />
CRect rect(0,650,830,520);<br />
CBrush m_Brush2;<br />
m_Brush2.CreateSolidBrush(RGB(255,255,255));<br />
dc.FillRect(&rect,&m_Brush2);<br />
m_Brush2.DeleteObject();<br />
}<br />
Thanks

No 
Are you leaking resources in your WM_ERASEBKGND handler??

Thanks for your help I used of this code but when I move a program Mem Usage of my program on TaskManager increase
Is it problem does my code has problem
I read Image on with
m_Image.Load<code> OnInitDialog() method<br />
<code><br />
<br />
BOOL CMyPicture::OnEraseBkgnd(CDC* pDC)<br />
{<br />
Image.BitBlt(pDC->m_hDC,0,0,593,420,0,0,SRCCOPY);<br />
return TRUE;<br />
}<br />
my code is this only but I have this problem
Thanks

Hmmm are you sure that's all you do in OnPaint() and OnEraseBkgnd()?
Your OnEraseBkgnd() wouldn't compile as you've shown it here.

It's ok
probably you don't neet to call DeleteObject
(destructor will do it for you)
Anyway, for your example is better use FillSolidRect()
and you dont have to worry about memory at all

Thanks for your help But why Mem Usage of my program increase can you help me
Thanks

If you want this question answered, you need to post some code. The IDE will actually try to show you where the leaking memory was assigned, is it in your paint code at all ?

Hey good people,
I'm a 2nd year IT student and i desperately need some help on how to implement network capability into my programs .
I got some tutorials on winsock2 but i dont know where to start. The tutorials i got all assume you already a genius programmer. If anyone know where i can get some winsock2 tutorials for beginners please forward me a mail if it's not to much to ask 205017517@cput.ac.za or if you can offer any help in this regard i would greately appreciate it.
Thank you everyone:
Phoenix

The MSDN library has much info...Here's a good place to start
Windows Sockets 2[^]
You don't need to necessarily be a "genius programmer" but it's so much easir if you have at least
basic knowledge of Windows programming for messaging and user interface plus knowledge of the
network protocol(s) you'll be using. Sockets is the easy part

Do you have any C/C++ programming experience? You said you are a beginner, so you will probably want to work on basic C/C++ programming before you jump into network programming, otherwise you are likely to be writing code and have absolutely no idea what it does ... which will make it impossible to debug.
If you insist on jumping into network programming anyway, try this link to get you started.
If you decide to become a software engineer, you are signing up to have a 1/2" piece of silicon tell you exactly how stupid you really are for 8 hours a day, 5 days a week
