Declaring _declspec(dllexport) in front of each and every member is not needed. Just write like this in the dll:-
class _declspec(dllexport) CTest
{
public:
void fnTest()
{
...
}
};
In .EXE:-
class _declspec(dllimport) CTest
{
public:
void fnTest()
{
...
}
};
It will surely work.
};

Thanks in advance!

Use FindFirstFile(). It accepts a structure, WIN32_FIND_DATA.
ftLastWriteTime member of this structure contains the modified time.

There's also GetFileTime().

I don't believe you can connect to any Db server on a separate subnet (as implied by your post). 
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

Hello, I am Sauce! and this is my first post on these forums. In my current project, I am using DirectX (specifically, D3D) to create a small 2D game. In the current stage of my project, I am setting up D3D to render textured quads, following along with the tutorial that can be found here, at www.gamedev.net.
I am getting two compile errors in my code, both of which are related; they are:
.\BiggerFish.cpp(114) : error C3861: 'Render2D': identifier not found
.\BiggerFish.cpp(204) : error C2365: 'Render2D' : redefinition; previous definition was 'formerly unknown identifier'
The first of these errors refers to my Render() function:
void Render()<br />
{<br />
if( g_pd3dDevice == NULL )<br />
return;<br />
<br />
g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0 );<br />
<br />
g_pd3dDevice->BeginScene();<br />
<br />
Render2D();<br />
<br />
g_pd3dDevice->EndScene();<br />
<br />
g_pd3dDevice->Present( NULL, NULL, NULL, NULL );<br />
}
and the second refers to my Render2D() function:
<br />
void Render2D()<br />
{<br />
g_pd3dDevice->SetVertexShader(D3DFVF_PANELVERTEX);<br />
g_pd3dDevice->SetStreamSource(0, g_pVertices, sizeof(PANELVERTEX));<br />
g_pd3dDevice->DrawPrimitive(D3DPT_TRIANGLEFAN, 0, 2);<br />
}
The compiler seems to think that I am redefining Render2D() when I call it on line 114 (in my Render() function), however I am not. Simply adding void in front of Render2D() when I call it eradicates this problem, however I believe that this is actually incorrect and the way my code is currently written is the correct way. Can anybody tell me the correct way to be doing this?
EDIT: I should probably point out that I am using Microsoft Visual C++ 2005 Express Edition. I have the Platform SDK installed, and the DirectX8 SDK.

Try putting the Render2D() function above the Render() function in your source code. That way the compiler will have seen the Render2D() before it is called from the Render() function.
You may be right
I may be crazy

Is Render2D a DirectX SDK function then u may forget to include the desired header file that u need to for compiling i.e why it is giving "identifier not found"
Regargs

No, Render2D() is not a DirectX function, however Render() is. It is simpler to render the 2D stuff and 3D stuff seperately (for example, render the 2D GUI seperately from the game world)
Your thoughts are however, always appreciated 
PJ Arends, your suggestion works perfectly. It even solved another problem I was having with my code, whereby a small rectangle was not being rendered. Thankyou for your insight.
I know for a fact that this website will be of use to me in the future.

This must sound really stupid, but i can't access my button properties. I decided to do a full mfc project for the first time with visual c++ 7 and for now it's really a pain in the ass.
Here's my code in the buttonclick event.
if (this->Test2->Caption == "On")
this->Test2->Caption = "Off";
else
this->Test2->Caption = "On";
at first I tried without the this and it didn't worked either. What am i doing wrong?

What are Test2 and Caption?
Have you tried using GetWindowText() and SetWindowText()?
You may be right

What are these (Test2->Caption) where you change values of these
|
|
|
|
|
this looks like Managed C++.
have you thought asking in the C++/CLI forum[^] ?
|
|
|
|

Test2 is the name of my button and caption is the property of whats written on the button. It very possible that caption doesnt exist and i have to use text, but both doesnt work.
And as far as I know this isn't managed c++, unless I never done unmanaged c++ in my entire life.

I'm having problems with class redefenition errors (4 of them, plus 93 other errors about not being able to find class defenitions). Include guards are in place in every file but I'm still getting errors becuase the classes are dependant on one another and I can't figure out a way for all the dependancies to be satisfied and still not get any class redefenitions.
The relevant files:
game_main.cpp
requires stdafx.h and game_operations.h (class CGameWin)
tree_operations.h (class TreeOperations)
requires stdafx.h
GameDialog.h (class GameOptionsDialog)
requires stdafx.h, and game_interface.h (class CGameWin)
game_operations.h (class GameOperations)
requires stdafx.h, game_interface.h (class CGameWin), and tree_operations.h (class TreeOperations)
game_interface.h (class CGameWin)
requires stdafx.h, GameDialog.h (class GameOptionsDialog), and game_operations.h (class GameOperations)
As you can see, I need class CGameWin in both GameDialog.h and game_operations.h, which is a problem since game_interface.h needs GameDialog.h. It makes a loop. I can post the header files if you need me to, but it will take up a lot of space. Please help me out with this.

Header files should never need stdafx.h. Stdafx.h must be the first file included in all your cpp files.
Can you do a simple forward declaration in one of your header files and then include the actual header file in your cpp file?
You may be right
