Hi All
I have been puzzelled in a problem,
What have to do is, that I have some file names ( like 000001.doc, programming.doc, etc.) now I have to find out the files that are in hexadecimal (leaving file extension).
Please guide me to find out this
Thanks

Use isxdigit() on the file's name.

Ahh david's is a much easier way. Its in the following library as well!
#include <ctype.h>
int isxdigit(int c);

1) Retrieve the file list
2) Loop through each file. For every File name, loop through its name until the extension is reached and check to see if each character is either [0-9] or [A-F]. If its not, just do continue; and start back at the beginning of the loop again. Use this website to utilize the ANSI character set.

Remember, the letters can be either lower case or uppercase and have different ANSI codes.
3) Record the file names in an array. (Create a dynamic allocated array for big file names).

Try this idea:
char name[100] = "......." ;
char * p;
strtoul(name, &p, 16);
if( *p == 0)
{
}
else
{
}
Hope it helps.

I'm trying to in corporate a \n in a CString variable I thought that you could use the format function to do that. Here's the code:
CString look;
look.Format("Original text: <%s>\n"
"Uppered: <%s>\n"
"CompareNoCase says they differ!\n"
"Lowered again: <%s>\n\n"
"Conclusion: CompareNoCase doesn't work correctly!");
AfxMessageBox(look);
But then I keep getting the following errors:
c:\documents and settings\....cpp(102) : error C2664: 'void ATL::CStringT<basetype,stringtraits>::Format(const wchar_t *,...)' : cannot convert parameter 1 from 'const char [137]' to 'const wchar_t *'
with
[
BaseType=wchar_t,
StringTraits=StrTraitMFC_DLL<wchar_t>
]
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
Build log was saved at "file://c:\Documents and Settings\kmil\Desktop\tst\LEDs_try2\LEDs_try2\Debug\BuildLog.htm"
LEDs_try2 - 1 error(s), 0 warning(s)
could someone explain to me what i'm doing wrong?
Thanks,

if you use a parameter in the format of the CString::Format() function, you must provide an additionnal parameter...
CString str;
str.Format("Hello %s...!", "Kitty");

Instead of:
"Original text: <%s>\n"
"Uppered: <%s>\n"
"CompareNoCase says they differ!\n"
"Lowered again: <%s>\n\n"
"Conclusion: CompareNoCase doesn't work correctly!"
try this:
_T("Original text: <%s>\n")
_T("Uppered: <%s>\n")
_T("CompareNoCase says they differ!\n")
_T("Lowered again: <%s>\n\n")
_T("Conclusion: CompareNoCase doesn't work correctly!")
This is because you are compiling an Unicode application. The _T macro allows you to make programs for both Unicode and ANSI modes.

I've tried that... but then I get an "Unhandled exception at 0x102212de (msvcr80d.dll) in LEDs_try2.exe: 0xC0000005: Access violation reading location 0x59199e91..." error. And when you go to debug it opens up the file output.c and points to line 1627 which is:
while (i-- && *pwch)

i already answered...
you wrote this :
look.Format("Original text: <<font color=red>%s</font>>\n"
"Uppered: <<font color=red>%s</font>>\n"
"CompareNoCase says they differ!\n"
"Lowered again: <<font color=red>%s</font>>\n\n"
"Conclusion: CompareNoCase doesn't work correctly!");
but where are the parameters ?!!!

sorry I put up the wrong text...
I don't have any parameters so it's:
look.Format("Original text: \n"
"Uppered: \n"
"CompareNoCase says they differ!\n"
"Lowered again: \n\n"
"Conclusion: CompareNoCase doesn't work correctly!");

OK... I am working with an IDispatch-based interface that needs to be completely automation capable (i.e. it uses the Typelib Marshaller - no custom marshalling).
Now, AFAICT:
o I can pass structures over an IDispatch-based interface as the structures consist solely of automation-capable types
o I can pass arrays of automation-capable types over IDispatch-based interfaces using SAFEARRAY (possibly wrapped within a VARIANT)
(For now, ignore the fact that some clients, like VBScript, may be unable to handle these kinds of parameters.)
However, I cannot seem to find information telling me that both are possible at the same time. IOW, I want to pass an array of structures across an IDispatch-based interface. The only information I can find regarding passing arrays of structures indicates that I will have to serialize the data to a byte stream and then send the raw bytes over the wire wrapped in a SAFEARRAY of VT_I1 types.
While I am sure I can make that work, and can provide clients with information on how to decode the structures, this feels kinda 16-bit-ish to me, and not just a little quick-n-dirty.
So, does anyone know if it is possible to pass arrays of structures over IDispatch-based interfaces, or do I have to do the byte-stream route? If so, please point me to the relevant documentation.
Adva[Thanks]nce! (Cheesy, I know...  )
Peace!

In OnCtlColor function add this block of code :
Define in the header file as follows in the public section:
COLORREF m_color;
HBRUSH m_brush;
if (pWnd->GetDlgCtrlID () == IDC_EDIT1)
{
pDC->SetBkColor(m_color);
hbr = m_brush;
}
if (pWnd->GetDlgCtrlID () == IDC_EDIT2)
{
pDC->SetBkColor(m_color);
hbr = m_brush;
}
Somethings seem HARD to do, until we know how to do them.

HBRUSH CAnswerDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
pDC->SetTextColor(RGB(54,97,200));
return hbr;<br />
}<br />

Better way to Subclass both the Controls you can do whatever you want and use those classes.
Following link directs you for subclassing

Hi!
I'm trying to accomplish the following:
A main app having a derived CStatic class called CPauseAdm.
A regular MFC DLL having a derived CPauseAdm class called CPauseTestAdm.
I want to make a form of plugin system where the CPauseTestAdm can be used instead of CPauseAdm without being forced to recompile the main app.
So far, I have been able to contruct the CPauseTestAdm class in my main app and call a number of its member functions. But when I try to create the window of CPauseTestAdm the Create function always return 0 and I get just a hwnd=NULL. Could somebody tell me what I'm doing wrong ?
BTW. The CPauseTestAdm object is created by the DLL through a wrapper function. I have tried to create it's window in both the main app and through a wrapper function exported by the DLL but none of these methods worked. Create returns 0 either way...

You may do this by creating the Generalised class(i mean templates class) in you application so that you can create object of the class whatever you want
just pass the class name into template and use that class.. 
Hope i understood your question.

Huum, I don't understand what you mean by templates class ?
The class I'm deriving from is defined in the main app...
The derived class is successfully created by the DLL so that does not seem to be the problem but when I try to create it's window using Create(...), with parent set to the main apps window, the functions returns 0. Could there be some form of resource problem even though the class derived in the DLL is just a CStatic ?

Check whether the provided parent of the main apps is correct is valid in the DLL.

Yes, the provided parent has correct type (CView) and seems valid.
