I use FILE to read datas from file.But it does not read full datas.
For Ex: if my file have 9 datas it reads only 6 datas then it jumped out from the loop.
when i see the YCS file.. it contains 9 datas, so no problem in writing.
Problem only in reading data. THis is my code...Whats the problem???Pls help me.
void ReadThermodata()
{
char FPath[] = "C:\\SelCompLst.YCS";
FILE *fp;
SThermoData pData;
if((fp = fopen((LPCTSTR)FPath,"r"))==NULL)
{
return;
}
int cnt = 0;
while( fread( &pData, sizeof( struct SThermoData ), 1 ,fp ) )
{
ThermoDataList.push_back(pData);
cnt = cnt + 1;
}
}

This is just a wild guess, try opening the file in "r+b" mode...
when the file is opened in text mode,there is possibility for the file to stop at ascii values like 26....
Hope this helps!

it seems its a binary mode data file, you need to open it with "rb", some value of data in binary mode is EOF in text mode.

We tried "rb" to open the file. But no use. It just read very few datas.

check what is the error, using ferror, _get_errno

Hello
I am looking for a image\video compression\decompression library to serve video over TCP\IP.
I get frames from my web cam in 320*240 resolution and RGB24 format so each frame is 320*240*3 = 230400 byte = 225 kbyte.
I am using Directshow to get streams from files or capture devices in server side. But I don't want use it also in client side. I am building my client in pure WinAPI. So I am looking for ANSI or only Win32 dependent open or closed free libraries for C\C++.
Can you suggest any ?
Best Regards,
Akin Ocal

How did you change the background color??

Seems like a paint issue.
Try overriding the OnEraseBkgnd() function.Write the code to put color on the screen there.
Hope this works out for you.(never tried this though...)
cheers!
PS:do comment or call the CDialog::OnEraseBkgnd( pDC ) first before putting in your paint code

Hi
Handle the WM_CTLCOLORDLG and place your painting code inside the handler.
<br />
<br />
HBRUSH CBkColorDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)<br />
{<br />
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);<br />
<br />
<br />
<br />
<br />
if(nCtlColor == CTLCOLOR_DLG)<br />
{<br />
hbr = CreateSolidBrush(RGB(2,22,222));<br />
}<br />
else if(nCtlColor == CTLCOLOR_STATIC)<br />
{<br />
pDC->SetBkMode(TRANSPARENT);<br />
hbr = CreateSolidBrush(RGB(2,22,222));<br />
}<br />
<br />
return hbr;<br />
}<br />
<br />
that's it

Serious resource leak there 
Those brushes should be created and destroyed
outside of the WM_CTLCOLOR handler!

Hi!
I am working with a class, derived from CRecordView. It is a basic customer-maintenance type module where you can either select the record by typing in the key number or scroll back and forth, uisng the standard RecordView buttons. Problem is that quick lookups and scrolling appears to me mutually exclusive.
The person who originally wrote the class solved this by coding the lookup like this:
MoveFirst();
while(!IsEOF())
{
if(m_Nummer==nr)
return TRUE;
MoveNext();
}
This works if the number of records are reasonable (say up to 5000). If I code the lookup with a normal filter and Requery then it is lightinly fast, but Moves fail, presumably because it tries to move within that result set of one record.
Can anyone suggest a solution where I can:
a) Just type in a number and have it pull up the record and
b) be able to use previous/next navigation?

Have you tried checking IsBOF() also?

Yes. If I set m_strFilter and do a requery, I find my record. I then clear m_strFilter. If I then hit previous/next the framework will kick off an extended fetch that will error with 100 (SQL No DATA).
What does work, but is kind of ugly is this:
Open the table, scroll through all records, for each do a:
m_pSet->GetStatus(rStatus);
m_Index[m_pSet->m_Nummer] = rStatus.m_lCurrentRecord + 1;
This builds an index of all records and their absolute numbers. Then in my lookup routine:
m_pSet->m_strFilter = "Nummer=?";
m_pSet->m_Nummerfilter = m_persGrund.m_persnrEdit.m_set.m_Nummer;
m_pSet->Requery();
m_pSet->m_strFilter = "";
m_pSet->Requery();
m_pSet->SetAbsolutePosition(m_Index[m_persGrund.m_persnrEdit.m_set.m_Nummer]);
But this seems like a tremenous kludge for such a simple task?

Since the record has been found, why?

"Since the record has been found, why?"
You mean "Why hit previous/next" possibly after I have edited and saved? To go to th enext record. Anyway, that is what users do, don't they?

I have a class allowing us to display a balloon but it requires an exact position or a handle of a ctr. But when I create an icon on system tray, I don't know how to get the position of the icon on system tray & with the handle of the icon I can't display the balloon exactly. So plz help me
|

You don't need to know the position of the icon - let the system do the work for you.
You can use ShellNotifyIcon to show a popup balloon for you. Lookup the docs for the structure NOTIFYICONDATA, and look at NIF_INFO.
I'm pretty sure there's an article or two here on the subject.
Iain.
Plz sir... CPallini CPallini abuz drugz, plz plz help urgent.

I've seen NOTIFYICONDATA & NIF_INFO but that balloon just appears when we start our application. I'd like to make it appear whenever we want (click on a button for example)... Help me again plz
