Re: Getting alerts (messagebox) with an integer value

I got it working. added '&' before baSlots.

sscanf(m_1E2val.Mid(i*2, 2), "%x", &baSlots[i]);

now I get it correctly. still do not understand what is wrong with

sscanf(m_1E2val, "%x", &baBeaconSlots);

yeah, fixed my mistake...

in fact, "%x" reads 2 hexadecimal characters and writes a single byte... so, you'd have to write
::sscantf(m_1E2val, "%x%x%x%x%x%x", baSlots[0], baSlots[1], baSlots[2], baSlots[3], baSlots[4], baSlots[5]);
which is worse - IMO - as the little for() loop i provided you...

If m_1E2val is indeed a CEdit object, then this statement is in error. Are you sure it's not a CString object instead?

It is a CString type member variable of CEdit

I got it working. added '&' before baSlots.

sscanf(m_1E2val.Mid(i*2, 2), "%x", &baSlots[i]);

now I get it correctly. still do not understand what is wrong with

There's no such thing. It's either one or the other.

Since you are the only one that knows what baBeaconSlots is, we can only guess as to what the problem might be.

he certainly don't know exactly what he's doing (MFC is sometimes dark for newbies).
he might want to say a CString on a CEdit member variable...

hmm, seems that baSlots turned into baBeaconSlots, but anyway, it remains char[6].

but i fixed his problem now...

First create a view class by class wizard.

Add a CDocTemplate class member(pointer) to your App class.
lets say m_newView.

Now at InitInstance()

m_newView = new CMultiDocTemplate(
ID,
RUNTIME_CLASS(Document class),
RUNTIME_CLASS(Frame Class),
RUNTIME_CLASS(View class));

AddDocTemplate(m_newView);

for more detail just search in this site you will get lot many examples.

Thanx

This is one exmaple why the CDATA element type is used...

We use CDATA sections in our XML files so our product's scripting language can be embedded within the XML without freaking the XML parsers.

For example, we might have a script line like this:

iTag001 <> 10;

If you don't put that in CDATA and and XML parseer tries to interpret it, you will have trouble.

So, now we have a node like this:

<ONHIDE>
<SCRIPT>
<![CDATA[
IF iTag001 <> 10 THEN
iTag001 = 10;
ENDIF;
]]>
</SCRIPT>
</ONHIDE>

Instead of like this:

<ONHIDE
SCRIPT = '
IF iTag001 <> 10 THEN
iTag001 = 10;
ENDIF;
'>
</ONHIDE>

We use the straight XML COM calls and interface pointers to process the XML, so I can't help you directly with the XmlCDataSection.

close your workspace.
delete the .clw, .opt, .plg file.
then open the project workspace again.

the other reason that class view getting lost is that .ncb file gets read only attribute. Make sure that this file has read/write attrib.try deleting .ncb file too

Last method is

Make a Copy to another directory, but copy only the source (*.c, *.cpp, *.h, *.dsw, *.dsp and the resource directory)
When you open again the project you will have class info, if dont, then push class wizard button.

Contactless Smart Card library for programming with VC++ ?

Maxwell Chen9-Feb-06 22:33

Maxwell Chen

9-Feb-06 22:33

As we knew that the Microsoft WinSCard library (came from Visual Studio and from MS Platform SDK) supports the "contact-based" smart card (ISO 7816).

I have the questions below:
1) Does WinSCard library support also the "contactless"-based smart card (ISO 10536, 14443, and(or) 15693)?

2) If (1) is yes, is there any reference guide for implementing contactless smart card applications?

3) If (1) is no, is there any other SDK or library to do that, which is for Visual C++ and targeting WinXP?

Thank you.
