If kakan has interpreted your request correctly, there's also this:
MCI_OPEN_PARMS mciOpenParms;
MCI_SET_PARMS mciSetParms;
DWORD dwResult;
mciOpenParms.lpstrDeviceType = (LPCSTR) MCI_DEVTYPE_CD_AUDIO;
dwResult = mciSendCommand(NULL, MCI_OPEN, MCI_WAIT | MCI_OPEN_TYPE | MCI_OPEN_TYPE_ID,
(DWORD) ((LPMCI_OPEN_PARMS) &mciOpenParms));
if (0 == dwResult)
{
dwResult = mciSendCommand(mciOpenParms.wDeviceID, MCI_SET, MCI_SET_DOOR_OPEN,
(DWORD) ((LPMCI_SET_PARMS) &mciSetParms));
}

On my Windows 2000 machine, it's in the HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\et4000\Device0\Acceleration.Level registry value. A value of 0 indicates full acceleration and a value of 5 indicates no acceleration.

Hello all,
How can I customize the default border of a window to my own color or style?
Is there any way for this rather than using OnNcPaint() itself?
Thanks in advance!

The following questions just came into my mind:
Having high expectations for VS.NET 2005 and Managed C++, I asked myself whether it is possible to take my current unmanaged project and simply set the "Managed"-switch ("/clr" or something like that, I recall) and then recompile.
I then thought that this will only be possible if MFC would be recompiled as Managed, too.
Is this correct? Or can I have a fully managed C++/MFC application without a Managed MFC version? Or is my whole question stupid? C'mon Nish, give me a clue

Respected All
Regards
I sent a thread yesterday and also recived replies from respectable members but unluckily that did not work,
my post was.
-----------------------------
Respected all
Reagrds!
thanks for replies,but unluckily those did not work.
my yesterday query was.
---------------------------------------------
Respected All
I am engaged with filereading problem since long time, i readed the file but still problems are coming.
the dat file is in the following form.
-----------------------------------------
;sfad
;sdlfgs
;sdfjsd
;X Y Index
12 12 1233
34 45 1244
66 44 2435
45 23 3455
;fgksdghkdfhgdf
;dflghfd
23 67 6788
23 45 2334
-------------------------------------
now in the above file format i has to read only the lines that's starting without SEMICOLON and all the lines starting eith SEMICOLON has to skipp.and also while reading each line of the file I has to put the X,Y and Index value in seperate Array and the same process will be repeated each time for X,Y and Index value.
my code script is following
---------------------------------------
int val1,val2,val3;
int row=0;
char str4[50];
pfile=fopen("filename.dat",r)
do
{
fgets(str4,sizeof(str4),pfile);
if(str4[0]!=';')
{
fscanf(pfile,"%d",val1)
arr1[row]=val1;
fscanf(pfile,"%d",val2)
arr2[row]=val2;
fsacnf(pfile,"%d",val3)
arr3[row]=val3;
row++
}
while(!feof(pfile))
fclose(pfile);
-----------------------------
its reads all the data correctly but when there is a SEMICOLON in the start of the line then its skipp the next one line(immediate lines) and reads after it.
in the above case it skipp the line
12 12 1233
and
23 67 6788
because before these two lines there was a SEMICOLON line and due to it skipp the immediate lines.
and except these 2 lines it reads all the lines accordingly,
I dont know why this problem is coming,, pls guide me that what is the best method in this case while i am reading the above file format.
waiting for + response.
------------------------------------------------------------------
The respected members suggests that use
int val1,val2,val3;
int row=0;
char str4[50];
pfile=fopen("filename.dat",r)
do
{
fgets(str4,sizeof(str4),pfile);
if(str4[0]!=';')
{
sscanf(str4,"%d",val1)
arr1[row]=val1;
sscanf(str4,"%d",val2)
arr2[row]=val2;
ssacnf(str4,"%d",val3)
arr3[row]=val3;
row++
}
while(!feof(pfile))
fclose(pfile);
--------------------end of thread----------------
remember that i am working on VC(MFC) envirnment,
but after execution like the above code it give error,and the error window come although there is execution error and compilation is succeffull.but did not execute.so if any MFC related method then kindldy guideme
so needs suggestion 1ce again,plz.

I somehow cannot understand this. Have you run the debugger to see why it skips the next line ? Is the fgets skipping one line when reading the file, or is fgets OK and your code not handling that one line (due to the str4[0]!=';' )?

Use this code..
I used MFC...
CFile fRead;
if (fRead.Open ("test.txt",CFile::modeRead))
{
CArchive aRead(&fRead,CArchive::load);
BOOL bDataAvail;
CString csReadString;
while ((bDataAvail = aRead.ReadString(csReadString)))
{
// Don't display line with semicolon
// If you sure about the first char is semi colon
// then you can use this statment
// against current (csReadString.GetLength() > 0 && csReadString[0] == ';')
if (csReadString.GetLength () == 0 )
continue;
if(csReadString.Find(";") > -1)
{
// Don't do skipp this
continue;
}
else
{
cout << endl << endl << "Read is " << csReadString.GetBuffer (0) << endl;
int val1,val2,val3,val4;
sscanf(csReadString.GetBuffer(0),"%d%d%d",&val1,&val2,&val3);
cout << endl << "Val 1 is " << val1;
cout << endl << "Val 2 is " << val2;
cout << endl << "Val 3 is " << val3;
}
}
aRead.Close();
fRead.Close();
}
