I think I have given you tha answer in the last mail.
any way If I have done any mistake them plz let me know.
I don't thing that scanf %x in allowed for string.
%x for interger
%s for string
you have problem there only and I rectify that in the last reply.

i don't know what you're trying to do, but if you're assigning 123456789abc into your char[3] variable, firstly, there's not enough characters to store it, and secondly, a C-style string must be null terminated.
now, please specify what format is supposed to be the char[3] because we are blind and so cannot help you much.
if you want some help, you have to give us the minimum informations for us to understand exactly what you're doing wrong.
so start it again, ,and please answer these questions :
1. how is defined m_1E2
2. how is defined temp
3. how is initialized baSlots ?
4. what is m_1E2.GetLine() supposed to do ?
5. is your 123456789abc value an integer or a string.
6. not a question but an important point : if your writing the 123456789abc integer into the temp string, temp must be at least 13 characters wide, so that the 13st character can be '\0' (null termination)...
hope you understand now.

Toxcct,
please see the code below :
unsigned char baSlots[6];
MessageBox(m_1E2val); //m_1E2val is member variable of edit
//box with type string
sscanf(m_1E2val,"%x",&baSlots);
now, when I check in debug,
after entering "123456789abc" in the editbox and on reaching the function with the above code,
with MessageBox(m_1E2val), I get correct string whatever I have entered.
but after
sscanf(m_1E2val,"%x",&baSlots)
in the debug window I see baSlots as
[0x0] 0xbc '¼'
[0x1] 0x9a 'š'
[0x2] 0x78 'x'
[0x3] 0x56 'V'
[0x4] 0xcc 'Ì'
[0x5] 0xcc 'Ì'
I am wondering where the 1234 went?

change the sscanf(m_1E2val,"%x",&baSlots); into this :
for (int i = 0; i < 6; i++) {
::sscanf(m_iE2val.Mid(i*2, 2), "%x", &baSlots[i]);
}
actually, i read here the hexa characters 2 by 2...

err.
I get Unhandled exception 0xc00000005 Access violation

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...
kk_vp wrote: still do not understand what is wrong with sscanf(m_1E2val, "%x", &baBeaconSlots);
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
sscanf(m_1E2val, "%x", &baBeaconSlots);

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...

baBeaconSlots is also
unsigned char[6], just like baSlots

How to add one more window in MDI application project.I Created the project.But now i want to include it.
How can i do this?
|
|
|
|

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.

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.
