i'm using the following code in my SDI application:
void CMyView::OnDraw(CDC* )
{
CMyDoc* pDoc = GetDocument();
ASSERT_VALID(pDoc);
if (!pDoc)
return;
Graphics graphics(m_hWnd);
SolidBrush brush(Color(255, 0, 0, 0));
FontFamily fontFamily(L"Times New Roman");
Font font(&fontFamily, 20, FontStyleRegular, UnitPixel);
RectF rectF(0.0f, 5.0f, 140.0f, 40.0f);
StringFormat stringFormat;
stringFormat.SetAlignment(StringAlignmentCenter);
graphics.SetSmoothingMode(SmoothingModeAntiAlias);
graphics.DrawString(L"Text", -1, &font, rectF, &stringFormat, &brush);
}
but when i run the application, the following message is displayed and application does not contiues furter:
Unhandled exception at 0x7c918fea in Dxf.exe: 0xC0000005: Access violation writing location 0x00000010.
the above code works fine for dialog classes. what might possibly be wrong?

Well..if you say so...
I was wrongly calling GdiplusShutdown(m_gdiplusToken) here:
BOOL CMyApp::InitInstance()
{
...
m_pMainWnd->ShowWindow(SW_SHOW);
m_pMainWnd->UpdateWindow();
GdiplusShutdown(m_gdiplusToken);
return TRUE;
}
instead of here:
int CMyApp::ExitInstance()
{
GdiplusShutdown(m_gdiplusToken);
return CWinApp::ExitInstance();
}

Good day,
Im posting this up here bec. there is not much interaction on Embedded/Mobile section but here on Visual C++ a lot of good people come.
Anyway,I'm using Embedded Visual C++ 3.0 on my development. I'am given so LITTLE TIME to do my task, so I'm planning to bring my task at home. Unfurtunately my pc at home is stand-along(doesnt have network -thou I have network card but can't afford yet to have an internet con.). I wanted to run the emulator(Pocket PC 2002) at home but the protocol used is TCP/IP. My Emulator cant connect to the Platform manager do I cant transfer files and debug my program. I've search here in the office on how to connect emulator with active sync (see site below).
.(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devguidesp/html/sp_intro_to_the_ce_emulator_zjht.asp)
However, I dont have that null modem cable nor serial cable at home. Can anybody help me how I could communicate my emulator with EVC3.0?
Any suggestion would be a great Help.
Thanks

I have no experience in Mobile programming, but if you need network connection you can install Microsoft Loopback driver.
it work like a NIC.

Good day,
I have tried to install MS Loopback and yes I do have network connection, however, when I ran the emulator, EVC3 emulator platform manager could not connect.
Anyway thanks Iman, I've learn something.
have a nice day.

Hi,
I know it's bad practice to disable warnings but I'm fighting my way through lines and lines of irrelevant information in the Output window to find my TRACE output.
Is it possible to temporarily switch off DLL loading messages such as:
'XYZ.exe': Loaded 'C:\WINDOWS\system32\abcdefg.dll', No symbols loaded.
Thanks,
Simon

I have an ATL Composite Control (DLL) that that includes my own control (CMySlider) derived from CSliderCtrl.
Here is the message map of this control.
BEGIN_MESSAGE_MAP(CMySlider, CSliderCtrl)
//{{AFX_MSG_MAP(CPlayerSlider)
ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomdraw)
//}}AFX_MSG_MAP
END_MESSAGE_MAP()
When Composite Control is embedded in the Dialog or FormView, CMyControl receives notification, OnCustomdraw gets called and everything draws/works perfectly.
The problem is that when the Composite Control is embedded in HTML page, I’m not receiving notification at all and instead of custom slider I’m getting the standard windows control.
Does anybody know what should I do to make it work on the web page?
Any help would be greatly appreciated.
Thanks,
Lev

There are a lot of samples with ON_NOTIFY_REFLECT(NM_CUSTOMDRAW, OnCustomdraw)on this site. Do a search and ypu find a lot of references.

I seem to have the same problem, have you found a solution for this one?

Hello all,
This is my first post to this forum, so apologies in advance for the lack of clarity.
Im trying to assign an unsigned 16 bit word to a char array i.e. two 8 bit single bytes.
my value (u16 sum) contains the word value 24fa which I need to insert into the middle of a char array buff[100]. Obviously, I am concious of the fact that the array is of type char (8 bit), thus any allocation will shorten the original value e.g. buff[0] = sum //buff[0] only contains 0x24
Is there any way to change the word value to two 8 bit singular bytes for storage?
Or is there another way via strcat/memcpy etc..etc
Many thanks in advance.
Stu

BYTE b1 = value & 0xff;
BYTE b2 = (value >> 8);
or
WORD *pw = &value;
BYTE *pb = (BYTE *)pw;
// now, pb[0] is the first byte of your WORD and pb[1] is the second
etc..

You can use a union. This union can be used to extract the individual bytes of most of the primitive data types. You can add more types as needed.
typedef union
{
double Double;
float Float;
UINT Int;
USHORT Short;
UCHAR Bytes[sizeof(double)];
} UnionBytes;
UnionBytes ub;
ub.Short = your_short;
your_string[x] = wb.Bytes[0];
your_string[x+1] = wb.Bytes[1];
I know you didn't ask this but you can do something similar to access the bits of a byte :
typedef union
{
UCHAR Byte;
struct
{
unsigned Bit0 : 1;
unsigned Bit1 : 1;
unsigned Bit2 : 1;
unsigned Bit3 : 1;
unsigned Bit4 : 1;
unsigned Bit5 : 1;
unsigned Bit6 : 1;
unsigned Bit7 : 1;
} Bits;
} ByteBits

Hi
I have a very big problem, if you know the answer please please help me.
I have a .Xls file that it has just one column data ( in the type of float). I have to read these data from Xls file and put them on an Array to use in my program, and after some working, I have to write them to an Xls file(different from the first one). It should be as a function().
I`ll really appreciate for your quick replies.

The following VB code is FYI, you must change it to VC
////////////////////////////////////////////////////////////////
Public Function SheetToArray(strFilename As String, intSheetIndex As Integer, intRows As Integer, intColums As Integer, strArray() As String) As Boolean
'Declare objects
Dim excapp As Excel.Application
Dim excbook As Excel.Workbook
Dim excsheet As Excel.Worksheet
ReDim strArray(1 To intRows, 1 To intColums)
Dim intLoopR As Integer
Dim intLoopC As Integer
'Create objects
Set excapp = CreateObject("Excel.application")
Set excbook = excapp.Workbooks.Open(strFilename)
Set excsheet = excbook.Worksheets(intSheetIndex)
'Read the table and fill the array
For intLoopR = 1 To intRows
For intLoopC = 1 To intColums
strArray(intLoopR, intLoopC) = excsheet.Cells(intLoopR, intLoopC)
'excsheet.Range(excsheet.Cells(1, 1), excsheet.Cells(5, 5)).Select
Next intLoopC
Next intLoopR
'Close Excel
excbook.Close
excapp.Quit
'Clear the objects
Set excapp = Nothing
Set excbook = Nothing
Set excsheet = Nothing
SheetToArray = True
Exit Function
End Function

I know of two ways. The first is to use Excel's ODBC driver. The second is to use Excel Automation. In my opinion, the ODBC method would be easier for what you are doing.
