void Find(CString dir_path)
{
CFileFind f;
CString path = dir_path;
CString LISTOFFILES;
if(path.Right(1) != "\\")
path += "\\";

path += "*.*";

bool res = f.FindFile(path);

while(res)
{
res = f.FindNextFile();
if (!f.IsDots()&&!f.IsDirectory())
LISTOFFILES+=f.GetFilePath()+"\n";

}
}

LISTOFFILES now contains all names of files which are in the dir_path directory(not including subfolders)

Example : Find("c:\\downloads\\")

CAsyncSocket connect time

GDavy11-Apr-05 0:11

Hello there,
Is it possible to define the time a CAsyncSocket object will hang in a Connect call before it fails.. Currently my app is kind of slow when the connect fails...
So I would reduce the connect time if it is possible
Thx for any help
Davy

Look for this Function CAsyncSocket::SetSockOpt for setting connetion Timeout feature

Hi,
I tried to use FormatMessage API to format variable argument that passed to a fuction, but it only delete all '%' characater with no thing else!
please help me.
my code :
void CEllepsisDlg::Log(CString x,...)
{
CString strTempInput;
strTempInput = x;
va_list marker;
va_start( marker, x );
LPTSTR lpFprmatedMessage;
va_start( marker, x );
strTempInput=x;
FormatMessage(FORMAT_MESSAGE_FROM_STRING,
LPCSTR(strTempInput),
NULL,
NULL,
(LPTSTR) &lpFprmatedMessage,
2048,
&marker);
char * tt=(char*)&lpFprmatedMessage;
va_end( marker );
}
Confused | :confused:

Well looking at your code I think you got the params for FormatMessage slightly wrong. Try changing it to

void CEllepsisDlg::Log(CString x,...)
{
TCHAR fprmatedMessage[2048];

va_list marker;
va_start( marker, x );

FormatMessage(FORMAT_MESSAGE_FROM_STRING, (LPCVOID)((LPCTSTR)x), NULL, NULL,
fprmatedMessage, sizeof(fprmatedMessage), marker);

va_end( marker );
}

I havn't tested it, but I think that might work better.

[EDIT]Be aware that in this new scheme that i've created, nothing happens to fprmatedMessage when FormatMessage has finished. Make sure you copy the string into a CString before using outside the Log function, otherwise your program will crash. e.g.

CString myresult = fprmatedMessage;

If you only want to use it within the function, then you can use fprmatedMessage just like any LPTSTR.[/EDIT]

Hope this helps.

A question on visual studio

Hi,

I used to see a drop down in my visual studio editor(using vc++) which would list out all the classes in the file and the second dropdown would have the listings of all the methods.

While doing something, those two dropdowns have gone missing, can anybody help me to browse the menu options and add them back into my visual studio.

Thanks,

are you using visual C++ 6 or .NET 2003 ?

if you're using VS.NET, you will find those comboboxes heading the source files (when you open one...).

The Wizard Bar is only available in VS6.
Since you are using the .NET studio, you can activate the drop down combos by :

Tools->Options->Text Editor->C/C++->Navigation Bar

I found that the navigation bar option is checked. Relaunched the visual studio but not able to see the combos.

uncheck the checkbox, quit, then recheck it...

if not, reinstall Visual Studio Big Grin | :-D

Get yourself the microsoft directx 9 sdk[^] and look @ the 'CaptureSound' sample.

Hi,

I have this project. It is an installer with the following requirments:

1. Enumerate COM Ports and prompt the user to select one to use for a modem.
2. Then programatically install the modem on the COM port selected from either a unimodem .inf file or a Nokia 2285 .inf file without any intervention again.

I need your assistance (even if commercial in nature) to accomplsh this in C/C++ or VB.

Best regards.

XML file traversal ????

Ritu Kwatra10-Apr-05 21:27

10-Apr-05 21:27

Hi all,

I am developing a Win32 Console application that reads XML file and displays the data. I am importing msxml4.dll and then usiing the following code to create the instance of the DomDocument class

HRESULT hr;
IXMLDOMDocumentPtr pDocument = NULL;
IXMLDOMParseErrorPtr pParseError = NULL;
BSTR bstr = NULL;
VARIANT_BOOL status = NULL;
VARIANT vsrc;

CoInitialize(NULL);

hr = CoCreateInstance(CLSID_XMLDocument,NULL,_ CLSCTX_INPROC_SERVER,IID_IXMLDocument,(void**)&pDocument);

VariantInit(&vsrc);
V_BSTR(&vsrc) = SysAllocString(L"try.xml");
V_VT(&vsrc) = VT_BSTR;

hr = pDocument->load(vsrc,&status);
hr = pDocument->Getxml(&bstr);
cout << "Try.xml comtents: " << bstr;

if(bstr)
SysFreeString(bstr);
if(&vsrc)
VariantClear(&vsrc);
if(pParseError)
pParseError->Release();
if(pDocument)
pDocument->Release();

CoUninitialize();

when I compiled the program it gives error
'Getxml' : is not a member of 'IXMLDOMDocument'

when I run the application without calling getXML function it gives me run time error that unhandled exception in the application.exe 0xC0000005: Access Violation.
Can anyone tell me where I am wrong.
I ahve the following files in system folder
msxml2.dll,msxml2r.dll,msxml3a.dll,msxml3.dll.msxml3r.dll.msxml4.dll,msxml4r.dll.msxmlr.dll

One point where I suspect error could be as to crete instance using CLSID_DOMDocument40, IXMLDOMDocument4 but in my project it gives me error when I call the CoCreateInstance with the above mentioned parameters.

Thanks in advance.
