Noob mfc question:
What's the best way of creating forms like invoices and reports? Those reports have a strict layout.
What i got so far was printing pdf's or html. The problem with html is that though it's easyer to create..it's imposible to set page counts and so on.
Postscript would be a good ideea but i don't know how to display it in a MDI

I need to lock a file stream(opened using fopen) in exclusive write lock. I came across a code segment where the functions flock() and fcntl() were used to lock the file. I need to have the header files unistd.h and sys/file.h in order to use these functions but these header files are not available. I am using Windows XP and Microsoft Visual C++. From where can I download these files?
|
|

|

I think the flock() function, unistd.h and file.h header files are only for Unix. In Windows, you can try _lock_file() function. Another way is _locking() function. For first argument, specify the value returned by _fileno().
Alternatively you can try LockFile function as described at http://msdn.microsoft.com/library/en-us/dnucmg/html/UCMGch09.asp?frame=true[^].
Hope it helps.

Thanks for the hints. I tried using both _locking() and LockFile(). I did not use _lock_file() since it returns a void so I could not find if the file is opened by some other process or not.
if(_locking(_fileno(fd), LK_NBLCK, 10L )!=-1)
printf("Lock obtained on file!");
is always returning "Lock obtained on file!" even if the file is open by some other process and
if(LockFile(fd,0,0,0xffff0000,0))
printf("Lock obtained on file!");
else
printf("Could not obtain lock on file!");
is always printing "Could not obtain lock on file!" even if the file is not being used by any other process. I think the problem is with how many bytes to specify to be locked. I want exclusive lock on the whole file so as to ensure that I don't write to a file when the same is opened by some other process.

1.change the the id of static ctrl to some value say IDC_MOVING_TEXT
2.Set a timer using the SetTimer Function in the OnInitdialog function
3. In the on timer function call
GetDlgItem( IDC_MOVING_TEXT )->SetWindowPos( 0, x, y, 0,0, SWP_NOSIZE|SWP_NOZORDER);
decrement or increatement the x value to make the control move....

Use SetTimer & KillTimer functions

What do you need its not hard

You can use MoveWindow() to set the coordinates of the static control
Somethings seem HARD to do, until we know how to do them.

Suppose you have a dialog with a button on it. The dialog also has a static control with a variable associated as m_statictext. Now when you click the button the window changes its position. Say moves to (0,0) with some size.
This is only a general example. You will have to create a timer and then keep on changing the position of the window as per your requirement.(Also check for bounds)
//To test you can write this code on the click of the button and see the window changing its position
m_statictext.MoveWindow(CRect(0,0,100,100),1);
Somethings seem HARD to do, until we know how to do them.

yes use MoveWindow or SetWindowPos
and if you need to timer in your program use SetTimer(500,1,NULL);(of course i suggest see MSDN for SetTimer)
then declare WM_TIMER message
void CAnswer::OnTimer(UINT nIDEvent)
{
}
in the end use KillTimer(500);
----------------
for static control insert one static in form and change id and declare a variable for this control

Hi Friends,
I wanna some help on WinInet Programming.
I am writing a VC++ client which is supposed to communicate a web Server
written in C#.net.
I am able to send a request to Web Server but how to read the contents send by
WebServer can anybody help me in this ?
Following is my code:
HINTERNET hOpen,hConnect,hRequest;
BOOL retval;
DWORD dwErrorCode;//=12032;
CString data="cmdCreateSessionID";
hOpen=InternetOpen("HttpApp/1.0",
INTERNET_OPEN_TYPE_PRECONFIG,NULL,NULL,0);
hConnect=InternetConnect(hOpen,
SERVER_LAN_NAME,4000,
NULL,NULL,
INTERNET_SERVICE_HTTP,0,0);
CString method="POST";
CString url="index.html";
DWORD dwFlags=0;
hRequest=HttpOpenRequest(hConnect,method,url,
NULL, NULL, NULL, dwFlags, 0);
DWORD R1=GetLastError();
HttpSendRequest(hRequest,NULL,0,data.GetBuffer(),
data.GetLength());
dwErrorCode = hRequest ? ERROR_SUCCESS : GetLastError();
CString lpBuffer;
INTERNET_BUFFERS dwStruct;
DWORD dwNumberOfBytesToRead,dwNumberOfBytesRead;
dwNumberOfBytesRead=dwNumberOfBytesToRead=0;
BOOL retReadFile=InternetReadFile(hRequest,&lpBuffer,dwNumberOfBytesToRead,
&dwNumberOfBytesRead);
In the InternetReadFile function i am unable to read any buffer.

you can find the CRecordset in the web...
it can open the excel as database
void CExDlg::OnRead()
{
// TODO: Add your control notification handler code here
CDatabase database;
CString sDriver;
CString sDsn;
CString sFile,sPath;
//find the excel in main exe folder
GetModuleFileName(NULL,sPath.GetBufferSetLength (MAX_PATH+1),MAX_PATH);
sPath.ReleaseBuffer ();
int nPos;
nPos=sPath.ReverseFind ('\\');
sPath=sPath.Left (nPos);
sFile = sPath + "\\Demo.xls"; //name of excel
sDsn.Format("ODBC;DRIVER={%s};DSN='';DBQ=%s", sDriver, sFile);
TRY
{
database.Open(NULL, false, false, sDsn);
CRecordset recset(&database);
CString sSql;
sSql = "SELECT item FROM Regt WHERE item = 'iwant' "; //
// exe SQL
recset.Open(CRecordset::forwardOnly, sSql, CRecordset::readOnly);
BYTE line = 1;
// »ñÈ¡²éѯ½á¹û
while (!recset.IsEOF())
{
//¶ÁÈ¡ExcelÄÚ²¿ÊýÖµ
recset.GetFieldValue("item", sitem); // read out the item
line++;
//ÏÔʾ¼ÇÈ¡µÄÄÚÈÝ
m_listbox.AddString( sitem);

recset.MoveNext();
}
// close
database.Close();
}

tag.lib? 
Maybe check the documentation associated with that library and see what you're supposed to use. Is it an sdk that you need to install?

Thanx for your response.
I have downloaded TagLib 1.4, but i couldn't found any .lib file in that. I think that i have to use tag.lib or taglib.lib file.
If u know the path where it exists can u please give me the path where it exists. I haven't used any SDK, i just used TagLib namespace.
http://developer.kde.org/~wheeler/taglib.html. I found whole documentation about TagLib in this link but It doesn't mention which .lib file i need to include.
waiting 4 ur reply.
regards
Trinadh.

Maybe TagLib is supplied in source files ? So, you just need to add the source files to your project and that will work (not sure if this is the case thought)
