hi all,
Please see the function below, and let me know if there is something wrong.
It is working, but i don't know if this is the correct way.
void ListFiles(CString strFolder)
{
WIN32_FIND_DATA wfd;
HANDLE handle = FindFirstFile(strFolder+_T("\\*.*"),&wfd);
if(INVALID_HANDLE_VALUE != handle)
{
do
{
if(!(wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
{
//do some thing with func
}
else
{
//check if it is . or ..
BOOL bIsDot = FALSE;
if (wfd.cFileName[0] == '.')
{
if (wfd.cFileName[1] == '\0' || (wfd.cFileName[1] == '.' && wfd.cFileName[2] == '\0'))
{
bIsDot = TRUE;
}
}
if(!bIsDot)
ListFiles(strFolder + _T("\\") + wfd.cFileName);
}
}while (FindNextFile(handle,&wfd));
FindClose( handle );
}
}

Hello!
I'm in need of a simple graphing/charting library, capable of drawing line graphs (and hopefully a few other types).
However i intend to use it from several languages, so must be packaged as a standard DLL.
I've been searching forever, so any pointers will be greatly appreciated.
regards

There are some ActiveX controls at codeproject that may be of help. You may also try www.sourceforge.net and codeguru.com.

I need information on how to read an image stored in a database into an IStream object.
I have been able to read in into a _variant_t OR CComVariant object. How can I get it into an IStream Object to use with Gdipus::Image.
Thank you

I need to have a vector of a class inside another class, but can't seem to get it to work:
class ca{};
class cb{
protected:
vector <ca *=""> va;
};
I included <vector> in cb.h along with ca.h but the compiler gives the following error:
d:\vectest\cb.h(3): error C2143: syntax error : missing ';' before '<'
Anyone know how to use vectors of one class inside of another class?
any help would be appreciated,
George

vector is a template.
#include <vector>
using namespace std;
And in the class cb you should write vector<ca> va;
|
|
|
|
|
OK, I'm using the files created by the wizard. In which file would you put the "using namespace std;".
Also, I am generating the ca using
ca *cax = new(ca);
Wouldn't the * be needed to hold the pointer?
Thank you,
George

"using namespace std;" can be written in the file where you write "#include <vector>".
I don't understand your second question.

Hello,
How can I use SetRedraw function to prevent device content flicker in OnDraw method?
I don't wanna use memory DC.
Thank u in advance.
|
|
|
|
|
SetRedraw() won't help to avoid flicker in OnDraw(). You'll have to use a memory DC to do that.

Hello, everyone!
I want to read data from serial port under Linux environment
using C. Are there some tutorial or sample codes that I can make
a reference?
Thanks in advance,
George

Search www.sourceforge.net and see what projects there may use the serial port.

Thanks, John buddy!
I have searched some projects. But they are too huge, for example,
a model dailer. I want to know whether there are some tiny samples,
one or two hundred line example?
regards,
George

hey i'm used to c++.i want to learn visual c++ comprehensively.can anyone suggest a good site or book for me so that i can apply myself?

It depends what kind of development you're into I guess. If it's just straight unmanaged Visual C++ (which I assume it is since you don't mention .NET), it's then a case of whether you're going down the MFC route, or using just the Win32 API or WTL.
Whatever you end up doing it's probably no bad thing to learn about Windows programming without the assistance of any libraries, in which case, something like Programming Windows by Charles Petzold is an excellent choice.
Alternatively, I can recommend Programming Visual C++ by Kruglinski, Wingo and Shepherd (there's a new release that also covers Visual C++ .NET) and it covers the basics of Windows programming, the majority of it is dedicated to MFC but with some ATL and COM also covered. For MFC in particular I would also highly recommend Jeff Prosise's Programming Windows with MFC.
Alternatively, there's loads of code and articles on the internet that can be used. I'm not aware of any WTL books, but there are some excellent articles on this site about how to use it, so I'd recommend maybe one or two books to get you into it, and then use articles here and elsewhere to supplement.
Of course, this all hinges on you learning how to use C++ and the standard library so once you start using Visual C++ you can actually build things, rather than just knowing how to display list views etc.

Immodestly I would recommend my own Visual C++.NET Bible. While Jeff's (Prosise) book is very good, I believe I cover several integral Windows programming topics better (COM, database, XML, etc.)

You can set a column name via numerous different ways - starting from filling LVITEM structure and sending a message to control.
Anyway:
all those ways use something like "iSubItem" - and thats the number of column to accomodate the text. Dont have MSDN by my hands - take a look there.
Sincerely yours, Ilya Kalujny.

Hi!
I've done a pretty large software project (a planning system) in vs.net c++ that is very interface "intensive" developed om Windows 2000 and targeting both W2000 and WXP.
Yesterday I tested this system on Windows XP Prof. on a new mobile computer from Dell and..
...Interface stopped working! ARGGG! I tried to debug the code and found out that DoModal() and WM_TIMER seemed to worked completely different from Windows 2000. The WM_TIMER in different windows came randomly and only when I moved the mouse over different controls (!). Verified this with Spy++.
Two DoModal() couldn't be done after each other (doesn't matter where it was done in the code, it was just a question of time and not logic). When I did this, the program locked up completely and never recovered (it didn't crash or leave any exception).
Question: Why is their a difference between W2000 and WXP Prof.? Have anyone else experienced this problem?

Was this on the same instance of the CDialog class or on two different instances?
You'll probably need to post the section of code that is troubling you, so that we can provide more clues to what is going wrong.

This is one example of when two domodals doesn't work for me in one dialog.
// A function called from PreTranslateMessage in the main dialog of a dialog based mfc program
void CMainDlg::FunctionCalledFromPreTranslateMessage()
{
CDialogOne dlgOne;
if (m_dlgOne.DoModal() == ID_OK)
{
CDialogTwo dlgTwo;
if (m_dlgTwo.DoModal() == ID_OK)
{
// Dialog Two doesn't show, the whole program locks up on WinXP Pro but not W2000 (W2000 version tested on a standard machine 2x1.2 ghz, XP tested on a mobile Dell, just a few days old) 
}
}
}

Are you able to debug on the XP machine. The clue will lie in what is going wrong in the DoModal call to the CDialogTwo (assuming you are not doing any major work in the constructor).
I'd step into DoModal and see if anything is failing in there.
Does this dialog use any custom controls or any of the windows common controls ?
