1'. check byte sequence of original, database and generated from your code.

generally so. you need convert char[2] to unsigned char
like "FF" (char[]) -> 0xff (unsigned char)
annese wrote: 3.i am using fwrite function which i assigned hex string values into unsigned char variable
good. but to say, you must fwrite array of BYTE above.
example)
char HEX[9] = "FFD8FFE1"; //original string
BYTE BIN[4] = { 0xff,0xd8,0xff,0xe1 }; // converted one
x fwrite(HEX, 1, 8, fp); // wrong!
o fwrite(BIN, 1, 4, fp); // good!
check further.

thanks for the very helpful info

I got too long hex string because it is an image file, size about 4k. If there any standard function to convert hex to binary? If not it will take some times to convert it? tq

What is CPU Time?
Some body tell me that this program use 10% CPU Time.
what does him mean?
and
How can I write the code for check CPU Time of my program,
what's function support this issue.

You can use types in time.h[^] to find the execution time.

That means that the program was using the CPU 10% of the time it was running. So, if it ran for 10 minutes, I would have used 1 minute of CPU time.
Max++ wrote: How can I write the code for check CPU Time of my program,
Use GetProcessTimes[^]. The total CPU time your program has used is the sum of the user and kernel times. The total elapsed time is the creation time substracted from the current time. You can express the CPU time as a % by dividing the total CPU time by hte elapsed time.

I want to detect whether a language pack is available, on selecting a particular language in my MFC application.Can anyone help me to sort out this problem??
It may be done through registry keys,but i am not getting that how to do it?
Plz help me.
Thanks..........

Look into this registry entry:
HKLM\SYSTEM\CurrentControlSet\Control\Nls\Language\
You are going to have to traverse through the entries and find the language code you are looking for. There should be code out on the web on how to traverse through registry entries to find a particular key.
Here you will find a list of Windows language codes:

So what is the first windows' parent windows.
BTW, I create the first window myself, not using the framework.
BOOL CWnd::Create(LPCTSTR lpszClassName,
LPCTSTR lpszWindowName, DWORD dwStyle,
const RECT& rect,
CWnd* pParentWnd, UINT nID,
CCreateContext* pContext)
{
ASSERT(pParentWnd != NULL);
ASSERT((dwStyle & WS_POPUP) == 0);
return CreateEx(0, lpszClassName, lpszWindowName,
dwStyle | WS_CHILD,
rect.left, rect.top,
rect.right - rect.left, rect.bottom - rect.top,
pParentWnd->GetSafeHwnd(), (HMENU)(UINT_PTR)nID, (LPVOID)pContext);
}

use CWnd::CreateEx

The code failed, why?
CWnd *pWnd=new CWnd;
LPCTSTR pClassName = AfxRegisterWndClass(CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW);
BOOL b = pWnd->CreateEx(0, pClassName, L"MyWnd",
WS_VISIBLE|WS_OVERLAPPEDWINDOW,
CRect(0,0,100,100), NULL, 1);

Hi everyone,
I am in need of help here. I have a dll which create a text file using FILE* and CFile class ( I tried both ways). At each line of text, text are "\t" delimited and "\n" at the end of text. The dll is created in C++ Visual Studio v6. There used to be a application (writen in version 6 as well) calling this dll and it works fine. Now, the application is ported into C++ VS2005 platform and calling this dll. It crashes at the end of file. Basically, it doesn't pick up the last "\n" and it run into while loop one more time. Since the additional loop doesn't see an EOF or "\n", it crashes. Can anyone tells me what's going on?
One interesting thing is that the same file reader function is used elsewhere in the same application and it works fine. Please help. I've run out of ideas and tests.

Possibly yoou should post the relevant code.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Everything is as usual. Here is a fragment of the code. Note that COXCsvFile class is a wrapper from Ultimate Toolbox.
COXCsvFile inFile;
CFileException fe;
int nRow=0;
//
// Open the input file
int nColumns = GetOurApp()->m_MIUtility.GetFileColumnCount(sFile, "\t");
if (!inFile.Open(sFile, CFile::modeRead, &fe))
{
return 1;//no record added
}
TRY
{
//inFile.GetColumns(4);
inFile.GetColumns(nColumns);
inFile.SetFieldDelimiter(_T('\t'));//set delimiter as tab
//
// Read the records in one at a time from the second table.
//
while (inFile.ReadLine())
{
inFile.ReadColumn(0, sSelCell);
inFile.ReadColumn(1, sNbCell);
inFile.ReadColumn(2, sRLAttempts);
inFile.ReadColumn(3, sTimeInActiveSet);
dSCellSCODE.strCell = sNbCell;
dSCellSCODE.strCI = strRowData;
m_aTempData.Add(dSCellSCODE);
nRow++;
}
inFile.Close();
}
CATCH_ALL(e)
{
inFile.Abort();
return 1;
}
END_CATCH_ALL

Are you sure it is ReadLine method failing (isn't, for instance ReadColumn)?
Probably your best friend is the debugger (and possibly you've to go deep into source, maybe even in the Toolbox's ones).

I stepped into the readLine(). It reads all the lines til the last one. For some odd reasons, it doesn't get the last '\n'. As the result, it tries to read an extra line. Since the next reading doesn't have a '\n' within the buffer size, it crashes.

Can someone help? I am stuck with this bug.

Hi All,
I'm not having a lot of luck declaring a combo box in the class code for my dialog resource. I'm using VC++ ver 2.0, non-MFC, Win32 with SDK calls only. I'm making additions to a large and complex legacy program.
Without the combo box declared in the code, the dialog opens fine when the program launches, but when I add the combo box, I get the following two message boxes:
First:
"Create Dialog failure"
Engineering Note ...
Dialog Creation Error
Be sure that there is a Dialog named, "" amongst the program's resources.
Then: an "OK" box:
Exiting due to Error
[8002] Window Create
Error code-20: Create Dialog failure
When I click on the OK, the entire program exits. I've typed the three last lines of each above, letter-for-letter from the messages displayed.
In my class in my .h file, I've declared the following:
ComboBox m_PhNoComboBox;
I added the following to my constructor in my .cpp file:
m_PhNoComboBox (this, WMM_IDC_MND_PHNOS_COMBO)
right after the constructor's function identifier and parameters line and the code builds, but gives that run-time error.
Does anyone have any idea what might be causing this? Should anything else be added?
Searching, I found nothing relevant about the error codes 8002 and 20.
Here's how I'm declaring the combo box in the resource description:
-------------------
WMM_MY_DIALOG DIALOG DISCARDABLE 101, 36, 296, 201
STYLE DS_MODALFRAME | WS_POPUP | WS_VISIBLE | WS_CAPTION | WS_SYSMENU
CAPTION "My Dialog"
FONT 8, "MS Sans Serif"
BEGIN
COMBOBOX WMM_IDC_MND_PHNOS_COMBO,137,22,137,164,CBS_DROPDOWN | CBS_SORT |
WS_VSCROLL | WS_TABSTOP
PUSHBUTTON "&Close",IDCANCEL,15,177,32,14
END
-------------------
Best regards,
|
|
|
|
|
check the WMM_MY_DIALOG definition in resource.h
