Other ways exist, from a simple loop to a more sophisticated (monitoring) service. But calling main() recursively should not be considered one of them.

Are you looking for barcode printing or barcode reading? If you are interested in reading barcodes then all you need is a barcode reader. Most barcode readers use RS232 to transmit data from the reader to the pc. If you want to print barcodes then i would suggest you buy a third party barcode creator.
Best Of Luck

( to add to the other answer )
doesn't the hardware barcode scanner come with an SDK that you can use ?
I don't know much about barcodes, but is it simply a unique number that gets scanned and used to track inventory items in a DB ?
Can you be more precise as what you need help with ? the hardware, the communication, the UI, the printing, the DB, ... ?

All of the bar code readers I have used use standard Serial Port (RS232) for communication. (Symbol/Welch Allen).
The barcode you are talking about are 1d barcodes. However, PDF417 (2d barcodes have the ability to store about 1900 bytes of binary data.)
Reading data from the Serial port is pretty trivial.
Wait for a single byte on the serial port. After reciving the first byte re-read on the Serial port for a Quater Second. You will now have all the data from the barcode. Do what ever you need to do with the inbound data. Go back to waiting for one byte.

 Can someone please tell me how to load and icon library(.icl) in VC++ ? I have heard they are 16 bit dlls. I have created a file mapping of the library. But when I try to use EnumResourceTypes API, it fails with error message "the specified file does not contain resource section". But the same file opens in VC++ resource edit and also in other icon editors.
Please help.

Hello!
I have two classes. In class 2, there ist a function call OnWriteStuff
Now i want to call that function which is in class 2 from class one. Take a look:
void CSampleView::OnDoWork()
{
CSampleDoc* pDoc = GetDocument();
POSITION pos = pDoc->GetFirstViewPosition();
while (pos != NULL)
{
CView* pNextView = pDoc->GetNextView(pos);
if(pNextView->GetRuntimeClass() == RUNTIME_CLASS(CVorschauView))
((CVorschauView*)pNextView)->OnWriteStuff();
}
}
but, it dont work, why?! How can I solve this?
thx in advance

Without telling us what problem/error you are seeing, a guess is the best you could hope for.

nothing happen
he don't call the function OnWriteStuff().
Maybe I'm on the wrong way. Can anybody tell me, how i can call a function, which is in an other view?!

How do you know? Have you set a breakpoint and stepped through the code one statement at a time?

in the other View where OnWriteStuff is.
I Also put there a MessageBox in it, if OnWorkStuff is calling, the MessageBox should appear. But the MessageBox didnt apear
can ya help me david?!

It does not make sense to put a breakpoint within the OnWriteStuff() itself when it apparently is not getting called. Go further upstream and put the breakpoint at/near the various places that OnWriteStuff() could get called. You should then be able to ascertain what conditions are failing that keep OnWriteStuff() from being called.

you re right. I solved the problem 
thx for that, but I have now an other problem.
in the OnWriteStuff() function, i call Navigate2(). The second class is a htmlview class. And normally, it must work, but it doesnt, why?!
ist shows me only that:
ASSERT(m_pBrowserApp != NULL);
where is my mistake?!
sorry for that damn poor english, i m from lettland
|
|
|
|
|
I've only used CHtmlView once. My usage of Navigate2() looked like:
Navigate2(_T("C:\\Winnt\\Temp\\Gymnast.html"), navNoHistory, NULL);

This simple class gives a compiler error under Microsoft Visual C++ .NET (7.1.3088) ...
error C2653: 'n1System' : is not a class or namespace name
error C2143: syntax error : missing ',' before '*'
#pragma once
#using <mscorlib.dll>
using namespace System;
__gc class test
{
public:
__delegate int MyDelegate(String *str, Int32 *n1, Int32 *n2);
test(void);
~test(void);
};
but compiles fine with only one Int32 declared in the _delegate
__delegate int MyDelegate(String *str, Int32 *n1);
Any ideas?
Mike

|
|
|
|
MSDN[^] says that the declaration of the Delegate should be outside the class? anything to do with that, coz i have no idea about VC.net

But why is it ok with two arguments, but not with three?
