sorry .bin is the file extension.

Yeah, but what is the INTERNAL format of the .bin file?
I could rename a .bmp file to a .bin file and it would still be a BMP file.
Watched code never compiles.

You have repeated this enough times; try answering the basic question: what is the format of the data in the file? If you do not understand what we are asking then you are never likely to resolve this issue.

you should present some code here and pin point the problem. May be you are not telling the problem as you should be telling (well im not sure about that tooo).

For example :
let's assume
that program uses a code like this:
#include<iostream><br />
<br />
<br />
void convertToASCII() {<br />
FILE *bmp;<br />
FILE *ASCII;<br />
bmp=fopen("1.bmp","r");<br />
ASCII=fopen("1.bin","w");<br />
char c; int x; <br />
while( (c = fgetc( bmp )) != EOF )<br />
{<br />
for( x = 0; x < 8; x++ )<br />
fputc( '0' + !!(c&(1<<x)), ASCII );<br />
}<br />
<br />
}<br />
int main() {<br />
convertToASCII();<br />
}<br />
<br />
you are looking for the function that converts back the bin file to bmp i guess..
as far as i understood your question is this..
am i right?

Hi everyone! I am writing a Bank Simulation program in C++ and it's a console application. In entering account passwords I do not want the characters entered to be shown on screen but to output the asterik character for every character entered as follows
while (true)
{
cout << "\n\nEnter administrator account password (press C to cancel): ";
int i(0);
char input;
while ((input = getch()) != '\r' && i < ADMINISTRATOR::ADMIN_PASS_LENGTH)
{
if (input == '\b')
{
if (i > 0)
{
password[i - 1] = '\0';
--i;
continue;
}
}
password[i] = input;
++i;
cout.put('*');
}
password[ADMINISTRATOR::ADMIN_PASS_LENGTH - 1] = '\0';
....
....
}
I used the function
getch() which provides unbuffered input. When a character is entered, it is saved and the asterik character (*) is printed on the screen. If the character entered is the backspace, the last character saved in the password buffer is cleared by setting it to '\0'. This seems to work fine.
Now the problem is that when the backspace character is entered, I also want to clear the asterik characters printed in the console window so that it can be seen that the asterik characters are being cleared but I don't know how I can clear the asterik characters as the user presses the backspace character. I need help.

Can't you just print a space character?

when I finished the wizard, a popup window showed the following text:

...
BTW, not only in vs2010, another application (mobicreator) showed the familiar text.
How to fix it?
Thanks.

1. new project
2. Visual C++/Win32/Win32 Console Application
3. Enter the name of the project (TestNamespace), click ok
Then it pops up a windows, show some code in html, with jscript.
I tried to copy it here, but it isn't support to be copied.
BTW, I have tried to repair it using the dvd, but it didn't solve the problem.

I just tried the same steps with VC++ Express and it worked fine. I can only suggest that your DVD is corrupt in some way. You could try getting another copy of the DVD, or alternatively get a copy of the Visual Studio 2010[^] trial to see if that works.

i want to hide the system menu that is displayed when u click the icon on the mainframe title bar. at the same time i want to retain the 3 buttons namely Minimize, Maximize/Retore and close.
i tried the following options
1) Removed the WS_SYSMENU window style. this results in removal of menu as well as all 3 the buttons.
2) Removed all the menu items as follows:
CMenu *pSysMenu = GetSystemMenu();
if(pSysMenu)
{
int nCount = pSysMenu->GetMenuItemCount();
for(int i=0; i<ncount; i++)
="" psysmenu-="">RemoveMenu(0, MF_BYPOSITION);
}
this second option works fine but it results in disabling of the Close button.
any suggestions are welcome.
also i am wondering whats that event handler which shows the system menu on click of that icon?
so that i can override that function and skip the displaying of the system menu.
thanks

Where should i put this handler in an MDI application. I have put it in the CframeWnd class but it gives error "overload function differs only by return type??
UINT CMainFrame::OnNcHitTest(CPoint point)
{
CRect rc;
GetClientRect(&rc);
ClientToScreen(&rc);
return rc.PtInRect(pt) ? HTCAPTION : CFrameWnd::OnNcHitTest(pt);
} what to do know

If you are compiling this code in VS2005 or later (which it sounds by the error given) then change the return type to LRESULT. Starting with VS2005 they changed the function signature from UINT to LRESULT.

Hello friends,
I am using MAC address to implement licensing in my application. As far as I know, MAC address of every system is unique and is very commonly used for licensing purpose.
For giving license of my application, I generate a unique key based on MAC address of a particular system and send that key to the customer. But the problem is that every time I format my system, I get a different MAC address. Doing this is problematic as every time customer format his system, he will need a new key (as his MAC address will also change on formatting his system).
Another problem is that if someone have two OS say XP and VISTA on his machine, he'll need two different keys to activate the license on both of the OS.
What I want, I get same MAC address even though customer keep on formatting his system (so that he can use same key every time). Also I get same MAC address on all the Operating Systems on a single machine (so that he can use same key on all the Operating Systems on his machine). Is it possible to do so? If yes then how? If not then why not? Please help me.
Right now I am using below code to get MAC address of a system:
std::string strMACAddress;
try
{
PIP_ADAPTER_INFO pAdapterInfo = NULL;
ULONG ulOutBufLen = sizeof (IP_ADAPTER_INFO);
pAdapterInfo = new IP_ADAPTER_INFO();
if (pAdapterInfo == NULL)
{
return;
}
int iResult = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
if ( iResult == ERROR_BUFFER_OVERFLOW )
{
delete pAdapterInfo;
pAdapterInfo = new IP_ADAPTER_INFO[ulOutBufLen];
if (pAdapterInfo == NULL)
{
return;
}
}
if ( iResult != ERROR_SUCCESS )
{
iResult = GetAdaptersInfo(pAdapterInfo, &ulOutBufLen);
if ( iResult != ERROR_SUCCESS )
{
delete pAdapterInfo;
pAdapterInfo = NULL;
return;
}
}
strMACAddress = pAdapterInfo->AdapterName;
delete pAdapterInfo;
pAdapterInfo = NULL;
}
catch (...)
{
}
Thanks in advance,
Best Regards

At the end of the day you're only querying a software function that returns the MAC address of the NIC.
So as long as the TCP drivers all query the same software function, you can use either the actual MAC address, or an arbitrary one - so long as the software function can return (a) the hardware encoded address and
(b)some other arbitrary value.
In fact, using only the MAC of the NIC is one of the laziest, sloppiest (and most easily defeated) licensing schemes I can think of.
You bigger problem is the fact that one copy of the software (and it's MAC-specific key) can be freely given to and used by anybody that is inclined to change their MAC address to suit the registration key. Been there done that, still got the t-shirt.

Pulling serial numbers from Motherboards & HDDs are typically more effective - This is what ZBrush 3.0 used to use.
But seriously, if your product is worth protecting it's worth spending a couple of $100 on isn't it?
You're far better off using a commercial protector that utilizes a virtual machine and obfuscates the machine code at the same time.
Armadillo was(is) a pretty good exe packer/encryptor/anti-debugger (http://www.siliconrealms.com/)
ASPack is also a b**tard to reverse engineer.
VmProtect is one nasty piece of work. Virtual machine and obfuscation (http://www.vmprotect.ru/)
The point is - these folks spend their working weeks coming up with protections schemes. You spend it coming up with the app.Would you service your own car if you kinda had a vague idea of what you were doing, while you knew you could afford to pay somebody that knew all of the idiosyncrasies of the particular model and any little tricks and tips for dealing with them??
If it's worth protecting - I'd suggest you do it properly.

Hi friend,
Thanks for reply. Yeah, you are right in that one should use third party licensing libraries. But my software is very cheap. It would cost around 5-8 dollars per license. Also I don't know if I could capture the market. So cannot afford to buy any licensing scheme.
But yes, as you said licensing based on MAC address is not a good approach. Can you help me in how get serial number of mother board?
3-4 months back, I did try to get serial number of mother board using WMI. But I could not do so. If you can provide some sample code about how to get serial number of mother board using any other mean (but using C++ only)?

Is there any reason why you are using the AdaptorName member of PIP_ADAPTER_INFO rather than the Address member?

Actually I found that Address member on many machines comes as an empty string. But it was AdaptorName member of PIP_ADAPTER_INFO which return the string such as "4960B27D-C24F-4C8B-886E-4E6BB93913C4".

When I debug a windows program, at program exit, when I attempt to step over the function ExitProcess(), the debugger catches an access violation exception. The code below is from the C run-time source.
void __cdecl __crtExitProcess (
int status
)
{
__crtCorExitProcess(status);
ExitProcess(status);
}
When I build and run a release version, the program appears to end properly and no errors are reported, but code that is waiting for the process to end
dwReturnCode = WaitForProgramToComplete(strProgramName, strProgramParameters);
results in the dwReturnCode now having the value of C0000005 instead of the value of 0. The fact that this number corresponds to the same value for the access violation exception when I debug, makes me suspect that the exception is still being thrown and handled a little differently. Does anoyone have some ideas on how to best try to determine the cause of this problem. Thanks.
