I have a app that needs to read and write stuff to the reg, I have my custom Reg functions in a seperate CPP file "RegHelpers.cpp" along with a header file "RegHelpers.h".
If I uncomment these 2 lines it gives a "unresolved external symbol" error for the functions in "RegHelpers.h"
//#define _UNICODE
//#define UNICODE
#include <windows.h>
#include <tchar.h>
#include "resource.h"
#include "RegHelpers.h"
I can not figure out what the problem is!!!
To make my program fully Unicode don't I need to change some Preprocessor settings?
Also, I used to use strings like this all the time:
LPSTR String = new char[256];
then I learnt about unicode, so I started doing them this way:
PTCHAR String = new TCHAR[256];
Do I need to do "new TCHAR[256 * sizeof(TCHAR)];"?
Also should I change them from PTCHAR to LPTSTR?
Do I really need to use the new operator on my strings?
Haha I'm really starting to hate data types.

You haven't really given enough information, but... Is RegHelpers.cpp compiled into a library? And if so, was the library also compiled for Unicode? If not, you'll get these errors. If it's not a library, does the header file use TCHAR and the cpp file use char? This will also cause these linker errors only for Unicode builds. Other than that, you'll have to give a bit more information.

No. The [] verison of new allocates multiples of the data size, so new TCHAR[256] allocates 256 bytes for non-unicode builds and 512 bytes for unicode builds.

It doesn't really matter - they are defined the same. Personally, I use PTCHAR for variables that are intended to point to a single character, and LPTSTR for variables that are a string, as that is what the names suggest.

You could allocate them on the stack like any other array, but if you need them to persist beyond a single function, then use new.

How simple can this be?
I want to draw a moving white line on a black screen at a fixed frame rate.
How can this be achieved?
I need to ensure that only one line is visible on the screen at any one time. But I'm having trouble getting my head around how this works with monitor refresh rates.
Currently I'm using DirectX, drawing on the back surface and then flipping the primary surface and back surface (with DDFLIP_WAIT). I draw a black rectangle then the white line and then flip. But it doesn't seem to behave as I would expect. I appear to see two or three lines on screen at once.
If I draw the white line, then black rectangle over it and then flip I should see only a black screen right? Wrong I still see the line!!! How?!
Can anyone help?

Hi there. I have a question for you all. At work, we have a large program that was written using VB6. The boss has decided that, for various reasons, it should be rewritten using VC++6. That's my job. He insists there's a program out there that can automate most of the porting but he can't remember the name. The only program I could find online was something by a company called Cicerosoft. They seem to have gone out of business, unfortunately, and I can't locate the software.
So, can any of you point me in the right direction? It doesn't matter if the software's free or not. Also, I'd be happy if all it did was automate the porting of the GUI screens and the prototypes for GUI functions (e.g., pressing buttons and such).
Thank you!

In VC6 you can import vb forms, through the IDE. It's in one of the books I have somewhere. I tried it once, but the only problem is that sometimes all of the controls don't import correctly, so a lot of the time I just had forms with textboxes on them. If you look and can't find this feature, post again and I'll see if I can find it for you on my system.

I just tried it. Just go to the menu (in VC6) and click 'Insert'->Resource. Choose 'Dialog' from the list of options and then click the 'Import' button. In the list of file types listed in the following file open box there will be a type for 'Visual Basic forms (.frm)'. don't know if this will get you where you want to be, but that VC IDE way.

Hi there. Thanks for the reply. It's definitely not perfect but it seems to work for the most part. We'll see how things go.
Thanks again!

This may have been brought up in previous posts and I apologize for rehashing an old argument. I am working on an application written in VS 6.0 and I would like to implement some functionality that would allow for the option to check for an update from a website. Someday, I would like to incorporate the ability to pull down the update. But for right now, I would just like to find a way to check for an update on a website. Any ideas or suggestions? Does anybody know of any articles on CodeProject for doing such a thing?

Is there an easy way to determine if a window is on top of all other windows?

How about GetTopWindow()?

I guess my question was a little vague. What I am trying to do is determine if my application is on top of all other applications. I receive data through a socket and when that data arrives if my app isn’t on top of all other apps I want to flash my app so it lights up on the task bar.. I have tried the following yet it still flashes even if the application is on top and has focus…
if(IsIconic() || GetDesktopWindow()->GetTopWindow() != AfxGetApp()->m_pMainWnd)
FlashWindow(TRUE);

if(IsIconic() || GetForegroundWindow() != AfxGetApp()->m_pMainWnd)
FlashWindow(TRUE);
Thanks

Can anybody know the answer to the folloing problem:
Given a window handle, how can we tell whether this
is a message box or not in C++ .Net.
Thanks!

To my knowledge, there's not. Like all dialog boxes, a message box belongs to the window class #32770.

Hi guys
Is there a simple way to play a sound that you previously included as a resource?. For only 17Kb it's annoying to have to add a extern wav file to the program.
Best Regards.

Are you asking or telling? If the former, see if this article is of any help.

Sorry David 
I've corrected my question.
Sometimes my english is not as good as needed to understand my questions.
I'm taking a look your article. I think is what I need to have the resource on memory.
But, what about to play a sound? 
Thanks
Doc

In Resource View Right Click On Your Resource Folder
Select "Import"
In The File Types Filter Select All Files Or *.wav If there is
Then Add The File U Want Thats it
Use ::PlaySound(MAKEINTRESOURCE(ID_MYWAVE,m_hwnd,SND_RESORCE|SND_ASYNC/*other parameters if u want to*/);
include the mmsystem.h header file and add the library winmm.lib in the debug and release configurations
I Have A Problem With PlaySound
The Problem I am Having Is when I exit my app the thread created for playsound with the SND_ASYNC returns a value of -1 i know that using ::PlaySound(NULL,0,0) the thread should be terminated safley i tried it but it fails i created a click sound for each mouse click on LButtonDown I use PlaySound with correct params on LButtonUp i use PlaySound(NULL,0,0) but the thread exits with -1 normal terminal should exit with 0
