Hi Guys,

I'm creating one dll in MFC and compile by release mode. In my project I have used 3 global variables in stdafx.h file

global variables are

char *g_strename;
char *g_streid;
char *g_isalary;

Say file name: employee (DLL created using MFC appwizard DLL)when I compile my project it shows linker error messages & warning messages

StdAfx.obj : error LNK2005: "char * g_strename;(?g_strPassword@@3PADA) already defined in employee.obj
StdAfx.obj : error LNK2005: "char * g_streid@@3PADA) already defined in employee.obj
StdAfx.obj : error LNK2005: "int g_isalary;@@3HA) already defined in employee.obj

this is followed by LNK4006 warning message.

please help me out, to rectify this. Just quick will do be great.
Thanks

transfer these variable to a .cpp file and use
extern char *g_strename;
extern char *g_streid;
extern char *g_isalary;
in stdafx.h

static char *g_strename;
static char *g_streid;
static char *g_isalary;

Copying one window & keep painting it....

Hey everyone:

Here's the scenario. I have a window that displays what I want the user to see the first time, but immediately they see it, I need to call a command that will send the window to all black. However, I want to keep painting the window with what the user saw the first time.

Is there a way of 'copying & pasting' contents from a window, so I can make it seem as though nothing has happend?

Thanks!

Best Debug Tools?

I am doing some eval of debug tools, and so far I don't really like any of them.

I've tried:
* Rational Purify (IBM) (not too impressed)
* Insure++ ( jury is out )
* AQTime

What's the consensus out there?
What's the best tool for finding memory leaks in C++?
What do you think of these tools?

Would love a tool that can do some CPU usage profiling too.

Thanks!

Oh, I current run under dev studio 2003 C++

If you yank it really hard using a chisel it usually just pops out of its socket. But it will be mighty hard to type properly without the Enter key.

check for the PreTranslate Message and check for the EnterKey scan code if it is true then simply write return true.

You can overwrite the PreTranslateMessage(...) method like this:

BOOL CYourDialog::PreTranslateMessage(MSG* pMsg)
{
	if ((pMsg->message == WM_KEYDOWN) && (pMsg->wParam == VK_RETURN))
		return TRUE;
	return CDialog::PreTranslateMessage(pMsg);
}

I doubt that you may need to disable the enter key in a dialog application...

If so then you can override the void OnOK() in your dialog class and avoid the calling of CDialog::OnOK() inside it.

tray icon specifics?

11-Apr-06 21:09

What are the limit to putting an icon on the system tray?
what size?
how many colors?

Everytime I get new artwork from our designers, they look crappy on the system tray.
What parameters should I give them in order to make a decent icon?

size: 16x16
colors: I think in Win 2K you can use 256 colors; in previous OSes it was 16 colors max. XP probably supports 32-bit icons now, but I can't quite tell now since the shadows are hard to detect against the blue taskbar.

EnumPrinters in Service doesn't work

11-Apr-06 20:57

Hi All,

I read in one of the forums that an EnumPrinters() for Network printers when used in a service , does not work because the service is running under SYSTEM account.

This is the problem. can any of u give me some inputs on how to solve this.I need to use

EnumPrinters() from the service.

are there any access rights that need to be given to the SYSTEM Account ? If yes, how do we set them ?

Any solutions ?

Thanks for the help.

A SYSTEM account service typically does not have full access to the network.
You can run your service under a specific account that DOES have network access.
You can imersonate a specific account which has network access from within your service which is running under the SYSTEM account.

There isn't a "recycle bin folder", each drive has its own directory (\recycled or \recycler depending on the file system).

For Accessing Recycle bin simple method is to get all the drives of the hard disk using _getdrive() API. Each drive contains 'Recycled' folder. using it you can get the information of the files in the recycle bin.
If you know any best solution then plz send it.
