Are you only accessing the window from within the thread that creates it? If not you are likely to have problems as Thread Local Storage is used extensively in windows.

Hi all,
I am working on converting some images into BMP format and the given images are in *.LL1 and *.LT1 formats. After converting them into BMP I have to display them in an interface that I am goin to build. (i.e when I select an Image file of any of those two formats fromt he 'open' menu item then it should display the image on a seperate window after doing all the process of changing the format into BMP. ( I am having the header information of the other two formats, but i don't know if it helps)
Anybody having ideas or suggestions of how to convert an image format in VC++, plz lemme know and I appreciate ur help.
I hope I am clear in problem description.
thanks in advance,
Pavan.

I have an options dialog in an app I'm building (an intranet bug reporter/tracker). I would like to be able to put an option in for the user to select whether or not they want the app to run at startup. How can I programmatically create a shortcut and place it in the user's startup folder if they choose this option? Thanks in advance

Check out the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
To create a link, check out the IShellLink interface.

Does anyone have some code snippets, or a suitable URL, to assist me in watermarking my C++ (unmanaged) code ?
Programming from a spec is like walking on water ......

|

hmmm... to be precisely.. these kind of questions are not very popular here...
you can't just watermark "C++ code"... you have to watermark the whole exe/dll/sys/etc file.
Don't try it, just do it!

The only time I've ever used the word "watermark" was in the context of an image within Word. How is it being used here?

maybe he's talking about obfuscating his code ?

I've seen enough of that without adding watermarks to the mix. Some folks just naturally write obfuscated code.

Hello,
I want to receive characters from the serial com with 115200baud. In general my code works but
it has a small bug and I don't know why. Maybe someone can help me.
My problem is: Sending >820bytes by a commercial program to my code, my code receives just 820
bytes only. After the 820bytes WaitCommEvent() doen't recognize any incomming characters any more.
Here is my code:
================
* Open com port:
m_hPort = CreateFile(sFile, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL);<br />
<br />
m_DCB.DCBlength = sizeof(DCB);<br />
GetCommState(m_hPort, &m_DCB);<br />
<br />
m_DCB.BaudRate = m_stCalibration.BaudRate;<br />
m_DCB.ByteSize = m_stCalibration.ByteSize;<br />
m_DCB.Parity = m_stCalibration.Parity;<br />
m_DCB.StopBits = m_stCalibration.StopBits;<br />
m_DCB.fDtrControl = DTR_CONTROL_DISABLE;<br />
m_DCB.fRtsControl = RTS_CONTROL_DISABLE;<br />
SetCommState(m_hPort, &m_DCB);<br />
SetCommMask(m_hPort, EV_CTS | EV_DSR | EV_ERR | EV_RXCHAR | EV_TXEMPTY);<br />
<br />
m_pListenerThread = AfxBeginThread(listener, this, THREAD_PRIORITY_HIGHEST, 0, CREATE_SUSPENDED, NULL);<br />
<br />
m_pListenerThread->m_bAutoDelete = FALSE;<br />
m_pListenerThread->ResumeThread();
* Read thread function:
listener (void)<br />
{<br />
DWORD dwBytesRead;<br />
DWORD dwBytesWritten;<br />
DWORD dwEventMask;<br />
BYTE szBuffer[MSGFRAME_MAX_LEN];<br />
DWORD dwOverlappedResult;<br />
DWORD dwLastError;<br />
BOOL bResult;<br />
DWORD dwDontCare;<br />
<br />
memset(szBuffer, 0, MSGFRAME_MAX_LEN);<br />
<br />
SetCommMask(m_hPort, EV_RXCHAR);<br />
WaitCommEvent(m_hPort, &dwEventMask, &m_stReadOver);<br />
while(1)<br />
{<br />
if(WaitForSingleObject(m_stReadOver.hEvent, 1000) == WAIT_TIMEOUT)<br />
{<br />
checkCalibration();<br />
continue;<br />
}<br />
<br />
dwOverlappedResult = GetOverlappedResult(m_hPort, &m_stReadOver, &dwDontCare, FALSE);<br />
if (dwOverlappedResult != FALSE)<br />
{<br />
bResult = ReadFile(m_hPort, szBuffer, 1, &dwBytesRead, &m_stReadOver);<br />
if(bResult != FALSE && dwBytesRead == 1)<br />
{<br />
m_stRingBuffer.RingBuffer[m_stRingBuffer.dwEnd].yChar = *szBuffer;<br />
m_stRingBuffer.dwEnd = m_stRingBuffer.RingBuffer[m_stRingBuffer.dwEnd].dwNext;<br />
m_pRingBufferFilled->SetEvent();<br />
<br />
}<br />
else if (bResult == FALSE && GetLastError() != ERROR_IO_PENDING)<br />
{<br />
}<br />
<br />
ResetEvent(m_stReadOver.hEvent);<br />
WaitCommEvent(m_hPort, &dwEventMask, &m_stReadOver);<br />
}<br />
}<br />
return;<br />
}
Thanks in advance  )

How to get the target file for a particular shortcut icon. This SHGetShortcutTarget API is only for CE OS. Is it possible to get the target for other OS.

Check out IShellLink::GetPath().

I am working in windows programming, in that I cant use this method (IShellLink::GetPath()). Is there any API to find out.

IShellLink is an (AP) interface. Why is it that you think it cannot be used? Here are a few examples of how it can be used:

use this little code
CCleintDC dc(this);
COLORREF ref;
int i=0;j=0;
for(;i<288;i++)
for(j=0;j<352;j++)
{
ref=RGB(red[i][j],green[i][j],bluew[i][j]);
dc.SetPixel(i,j,ref);
}

Can I declare a global variable in a DLL?
My variable is a object of Internal class that NOT exported.
Also my global object will use internally.
My dll is a "Regular DLL with MFC statically linked".
Does it cause a problem?

The same way you would in an EXE. If the variable is not within the scope of a function, it has file scope, thus it is global. If you want to use the variable in a different file from which it is declared, you'll need to extern it.

Hi,
how can I force WinXP to set the TCP/IP push bit when sending data on a socket that I created.

if you are using RAW_IP sockets, then yes.

i have an odd run time error occuring my app. it is a simple SMTP program. when i select button1 it opens a CFiledialog as it should if i select "cancel" it works as it should no problems, but if i select "ok" the selected file path is returned as it should, however when the message is sent no data is written to the log file.
this occurs even if the path returned is removed before sending the data it follows the same code path as if i had not selected a path
the button code is as follows
void CMail2Dlg::OnButton1()
{
UpdateData(); // saves control data to variables
// Create an instance
CFileDialog fileDlg( TRUE, NULL, NULL, OFN_ALLOWMULTISELECT | OFN_HIDEREADONLY, "All Files (*.*)|*.*||", this);
// Initializes m_ofn structure
fileDlg.m_ofn.lpstrTitle = "Attach File";
// Call DoModal
if ( fileDlg.DoModal() == IDOK) // seems to be the cause of the problem!!!!
{
CString szlstfile = fileDlg.GetPathName(); // This is your selected file name with path
m_att = szlstfile; //sets path to a variable of my main modal dialog
UpdateData(FALSE); //variables to controls
}
}
// the following code is writing of data to a file which occurs in various functions
ofstream logc ("logs.txt",ios::out | ios::app);
if (logc.is_open())
{
logc << rVal; // rVal is the data
logc.close();
}
please could any1 help
