Can I use the Setup Project provided with Visual Studio .NET for preparing Installation for my VC++ project?
Thanks

when built my program in VC++ 6.0,I frequently receive a message box displaying "this file has been modified out of the source editor , do you want to reload it?" , and after this, I find that the file is indeed changed and in turn some errors occured, how can this happen?
afterwards, I find a clue for this error: the file being modified each time is the same file named "DetailedDesign.h". and the file is changed typically when I make a call to "rebuild all".
so I tried setting the file "read only",and when I call "rebuild all", one error occured, following are all of the generated informations:
Deleting intermediate files and output files for project 'DetailedDesign - Win32 Debug'.
Error: Could not delete file "E:\my project
\DetailedDesign\DetailedDesign.h" : access denied。

What have you chosen as output directory for your Debug session ? Is it E:\my project\DetailedDesign\ ?
Where is this file located in your Source Browser ?
Is this file somehow auto-generated ?
~RaGE();
|
|
|
|
|
all of my source files including the "DetailedDesign.h" are in the dirctory "E:\my project\DetailedDesign\", and the Debug output directory is " E:\my project\DetailedDesign\Debug" as default

Can any one help me to find data encoding of received buffer with WSARecv() command.
Weather data send by client is in UNICODE or in ASCII format
E.g.:
WSARecv (AcceptSocket, &DataBuf, 1, &RecvBytes, &Flags, &AcceptOverlapped, NULL)
DataBuf.buff is in ASCII or in UNICODE
Regads,

Is upto you in which form you want to recv data

Using VC++.NET2003
I have written serial routines (ported from Apollo) as follows:
but I am finding that with a serial loopback setup
the leading bit is reset on all chars (ie. transmit 0xff and receive only 0x7f)
I have a feeling its to do with binary vs text mode but I am unable to resolve.
Code:
CSerial::CSerial (LPCTSTR pszCommPort, LPCTSTR pszMode , char LineTerminator)
{
m_strCommsPort = pszCommPort;
m_strMode = pszMode;
m_LineTerminator = LineTerminator;

I haven't looked closely at the rest of the code, but try adding
to the device control block configuration to make sure the UART isn't defaulting to 7 bit mode.

HI, I have found the error is not the software but the edgeport/4S USB serial port hardware I am using. I tested the software on a direct RS232 port and it worked correctly. I have since found that re-installing the edgport/4s 4 port unit and then re-instating RS422 has fixed the problem.

Hi all !!
I practise VC. When I code my program to create a file.
The first time when I click my button2 (create file) I receive a error "access pathdir to file is denied" but I can create file at the second click. I don't know why ??? Please,I need help !!
This's my code when click button2, I use MFC wizard (use dialogbase)
void CTestDlg::OnButton2()
{
// TODO: Add your control notification handler code here
char filename[100];
GetCurrentDirectory(100,filename);
strcat(filename,"\\RongVang.dat");
CFile f;
if(!f.Open(filename,CFile::modeReadWrite))
f.Open(filename,CFile::modeCreate);
f.SeekToEnd();
char s[100];
strcpy(s,"Test Create file");
f.Write(s,100);
}

the filename return format is not like this"C:\\ adir"
it return format is "C:\adir"
it can't use as a parameter in F.Open Function .

Thank so much !!
But how can i slove it ....
Can you show me .....
I've just program...
|
|
|
|

Why do you open the file two times?
i think there you get the error.
if(!f.Open(filename,CFile::modeReadWrite))<br />
f.Open(filename,CFile::modeCreate);<br />
Try this:
if(!f.Open(filename,CFile::modeCreate | CFile::modeReadWrite))
|
|
|
|
|
if(!f.Open(filename,CFile::modeCreate | CFile::modeReadWrite)) f.Open(filename,CFile::modeCreate);
The first click it will create file.
I want at the second click, third,4,5,.... click in button2, it will append my file, not delete and create new file like above !!
Can you help me ... !!!!!!!!!!!!
|
|
|
|
|
CString filename = _T("C:\\RongVang.txt");<br />
CStdioFile f;<br />
if(!f.Open(filename,CFile::modeReadWrite))<br />
f.Open(filename,CFile::modeCreate|CFile::modeReadWrite);<br />
f.SeekToEnd();<br />
CString s = _T("Test Create file\n");<br />
f.WriteString(s);<br />
dont forget to close your file.

Then use:
if (f.Open(filename, CFile::modeCreate | CFile::modeReadWrite | CFile::modeNoTruncate) != FALSE)
{
f.SeekToEnd();
...

Hi, i'm new around and i have a big problem. i have to make a program to log msn conversations into .txt files and i'm having trouble doing it. this is going to be my final college project so i need it to work before december
i found an article here in code project on how to retrieve conversations based on the windows title, i already fixed the code like this to get all the windows titles an display a textbox when it founds a conversation window. right now i'm sending all the windows names to a list box while i develop the whole app
<br />
OnInitDialog(){<br />
...<br />
EnumWindows(EnumWindowCallBack, (LPARAM)::GetDlgItem(m_hWnd, IDC_LIST_RUNNING));<br />
...<br />
}
static BOOL CALLBACK EnumWindowCallBack(HWND hwnd, LPARAM lParam) <br />
{ <br />
HWND hWnd = (HWND)lParam; <br />
CString strTitle;<br />
DWORD wndPid;<br />
<br />
if (IsWindowVisible(hwnd))<br />
{<br />
GetWindowThreadProcessId(hwnd, &wndPid);<br />
CWnd::FromHandle(hwnd)->GetWindowText(strTitle);<br />
strTitle.TrimRight();<br />
if (!strTitle.IsEmpty())<br />
{<br />
CListBox *pListBox = (CListBox *)CWnd::FromHandle(hWnd);<br />
pListBox->AddString(strTitle);<br />
if((strTitle.Find("- Conversation",0))!=-1){<br />
::MessageBox(hWnd,"Found","MSN",MB_OK);<br />
EnumChildWindows(hWnd, ChildWndProc,0);<br />
}<br />
}<br />
}<br />
<br />
return TRUE; <br />
}
the function that it's supposed to retrieve the text from the conversation windows is
<br />
static BOOL CALLBACK ChildWndProc(HWND hwnd, LPARAM lParam){<br />
static int i = 0;<br />
LPTSTR lptstr;<br />
HGLOBAL hglb;<br />
char windowclass[CLASS_SIZE];<br />
<br />
if(GetClassName(hwnd,windowclass,CLASS_SIZE)==0)<br />
return TRUE;<br />
<br />
string strTemp(windowclass);<br />
if((strTemp==string("RichEdit20W")) || (strTemp==string("RichEdit20A"))){<br />
::SendMessage(hwnd,EM_SETSEL,0,-1);
::SendMessage(hwnd,WM_COPY,0,0);<br />
::SendMessage(hwnd,EM_SETSEL,-1,0);
<br />
if (!IsClipboardFormatAvailable(CF_TEXT)) <br />
return TRUE; <br />
<br />
if (! ::OpenClipboard(NULL)) <br />
return TRUE; <br />
<br />
hglb = GetClipboardData(CF_TEXT); <br />
if (hglb != NULL) <br />
{<br />
lptstr = (LPTSTR)GlobalLock(hglb); <br />
GlobalUnlock(hglb); <br />
EmptyClipboard();<br />
CloseClipboard();<br />
::MessageBox(hwnd,lptstr,"MSN",MB_OK);<br />
pChatText->SetWindowText(lptstr);<br />
<br />
return FALSE;<br />
}<br />
}<br />
return TRUE;<br />
}
when i compile and run the program i don't get any errors or warnings but it doesn't retrieve any conversation.
i just can't figure out what's wrong or if this code just doesn't do the work.
i'm using Visual C++ 6.0 SP6 on W2K and MSN messenger 7.0.0813 to do this app
could somebody tell me what's wrong with that code in order to do the rest of the app or tell me if there's another way to retrieve msn conversations?
any help is really appreciated

Now MSN messenger no longer contain the RichEdit box.. so you can't reterive the conversation text using above method... any way you can try this link

What version? I'm using Windows Messenger v4.7 and it definitely uses rich edit controls.

Sir,
So Sorry, I am quoting on SmagGada remark in his/her post that he/she needs to reterive chat message MSN messenger 7.0. Sir, I believe you are using Window Messenger, it's still using same old RichEdit Ctrl for chat message!
