Re: Problem with COleDateTime obj - C / C++ / MFC Discussion Boards

Hello,

It's a bad (C/C++) programming practice and it will bother the linker if you include the header in more than one place. (Multiple defined symbols...). Besides that, if you place all your code in header files (no *.cpp file(s)) you'll not be able to create object files and executable code...

If you are talking about templates (I assume you are not), then you have to put all the code in a *.inl document or in the header file.

Hope this helps you. Smile | :)

... is the police. - Conspiracy brother

Blog[^]

bad idea, if you change the implementation all file dependant on that header file will be recompiled.

Also, I don't think the debugger will be able to step in the code.

anyway, bad idea, I sure others will give you other reasons why.

Thank you everyone.

Hello i am using datagrid control in Vc++.net.
when i set a float value to a cell, it returns the fol error.

my code is
***********
Datagrid->set_Item(1,1,System::Convert::ToSingle(textBox1->Text) );

Error
********
error C2664: 'void System::Windows::Forms::DataGrid::set_Item(int,int,System::Object __gc *)' : cannot convert parameter 3 from 'float' to 'System::Object __gc *'

The datagrid columns are of float type.

otherwise if i use toString function,
Datagrid->set_Item(1,1,System::Convert::ToSingle(textBox1->Text) );
it compiles well but, returns runtime error, cannot convert from target type to primitive type..

Pls help me

Hi to all,

I've got a big problem with the code below

CWorkRecordset::CWorkRecordset(CDaoDatabase* pdb)
: CDaoRecordset(pdb)
{
//{{AFX_FIELD_INIT(CWorkRecordset)
m_lUser = 1;
m_lCode = 0;
m_lDept = 0;
m_lWork = 0;
m_lSource = 0;
m_oStartTm = COleDateTime::GetCurrentTime();
m_nFields = 6;
//}}AFX_FIELD_INIT
m_nDefaultType = dbOpenDynaset;
}

The problem occours during the creation of the obj,
and only if:
- I'm running in debug mode
- The PC where Visual C++ Professional 6.0 (no service pack) is installed has Win XP as OS

Program crashes when it execute:
m_oStartTm = COleDateTime::GetCurrentTime();

If I run in release mode, no crash occours
If I run in debug/release mode in a Win 2000 PC, no problem
The state of obj m_oStartTm is "valid" before assignment

Can anybody help me? Confused | :confused:

Thanks in advance
Cristian

Have you stepped into COleDateTime::GetCurrentTime() to see what is causing the crash?

As I try to step into using F11 the program crashes, the debug window says:
Debug assertion failed!
File: winctrl5.cpp
line: 189

Before calling that function obj m_oStartTm.dt = 0.0000 & m_oStartTm.status = valid

I don't understand...

Hmm, this is inside of the CDateTimeCtrl::GetTime() method. Can you set a breakpoint in it and then check the call stack once that breakpoint is reached? I'm curious how you got there from COleDateTime::GetCurrentTime().

Another suggestion would be to change the initialization to:

m_oStartTm = COleDateTime(0);

and see what that produces.

Also, what does CWorkRecordset::DoFieldExchange() look like?

"Take only what you need and leave the land as you found it." - Native American Proverb

So, using m_oStartTm = COleDateTime(0); causes a compiling error(0);

DoFieldExchange is:
pFX->SetFieldType(CDaoFieldExchange::outputColumn);
DFX_Long(pFX, _T(cRSsbUser), m_lUser);
DFX_Long(pFX, _T(cRSsbCode), m_lCode);
DFX_Long(pFX, _T(cRSsbDept), m_lDept);
DFX_Long(pFX, _T(cRSsbWork), m_lWork);
DFX_DateTime(pFX, _T(cRSsbDateHour), m_oStartTm);
DFX_Long(pFX, _T(cRSsbSource), m_lSource);
where cRSsbUser is the name of a access table column

And finally, if I set a breakpoint in winctrl5.cpp, when i run the debug Visual C++ disable that brakpoint

Now in italy is quite late, i think I'll go sleepin an hour, if i apologize if i don't reply immediately
Thanks in advance, tomorrow i will try again Smile | :)

What about this instead:

m_oStartTm = (DATE) 0;

Even if this does pacify the compiler, I feel the underlying problem still exists. I just created a test program with a class derived from CDaoRecordset, and an Access table having a date/time column. The constructor looked liked yours and I got no assertion. At this point, I would suggest you do the same thing, and then start adding bits and pieces of code until the problem shows up. Make sense?

I apologize if i reply only now, I had problems with internet connection
I just want to ask if you have the same configuration I submit in my first msg, because if I use win 2000 I have no problem!

"Take only what you need and leave the land as you found it." - Native American Proverb

Hello, I searched this message board and I did not find anything about changing the color of the scrollbar in my edit box so I decided to ask. In my dialog box I have 4 edit boxes and I want to modify the style of the scrollbar (CSS does this in webdesign). See an example here of CSS scrollbar style modification Smile | :)

Problem Context: I am writing 2 functions in a dll namely "Fun1" and Convert(thread function).
I am creating a thread within a Function "Fun1" which is called from a tool.

The code for this as follows:
Fun1(Long lChannelNos )
{
HANDLE h1;
NumberOfChn(/*declared at file level of long type*/) = (long)lChannelNos ;
LPDWORD dwTh ;
LPVOID data ;
data = (void *)NULL ;
h1= CreateThread(NULL, // default security attributes
0, // use default stack size
Convert, // thread function
data, // argument to thread function
0 , // use default creation flags
dwTh) ; // returns the thread identifier
if(h1 == NULL)
{MessageBox((HWND)hDIAdemWndGet(),"Failed to create thread","Failure
Thread",MB_OK);
return ;
}

CloseHandle(h1);
return ;
}

DWORD WINAPI Convert(LPVOID lpTh)
{
Here I create linked list, dynamically on heap, using pointers to structure of data type given below.

Thus depending on size of "NumberOfChn",(any value between 1 to 200) the memory requirement varies.
For NumberOfChn = 1 the linked list would consume memory of 40503 bytes(40.5Kb).
}

Problem facing:
1) For NumberOfChn = 1 to 10 (any value) I do not get any error after executing function "Fun1". But if I happens to close the tool, the following error is received

Error: Debug assertion failed
Program: c:\Program Files\National Instruments\Diadem 9.1\Diadem.exe
(This is the Tool from which i make call to "Fun1")
File : dbgheap.c
Line:1011
Expression: _CrtIsValidHeapPointer(pUserData)

2) If the value of NumberOfChn goes beyond 15 it gives
MEMORY ACCESS VIOLATION error.

thats all....
waiting for any solution.

What are you expecting this to do? These type of statements can be removed as they do nothing.

There's too much code here to wade through. Have you tried scaling the problem down to something more manageable? A few dozen lines of code is all you'd need to make a linked list that can easily be debugged. After you are certain that you can add to, and delete from, the simplest of lists, only then should you add all of the other code.

Friends,
How can we display "line numbers" in the editor of Visual C++ 6.0 IDE?

In case of VS.NET, the line numbers can be invoked from:

Tools->Options->Text Editor->C/C++->Line numbers

Is it possible with Visual C++ 6.0 ? If yes, then how ? Also please tell me about the "shortcut keys" to display line numbers in case of both Visual C++ 6.0 and Visual C++.NET+

Look in the lower, right corner of the IDE. You will see line and column number.

hmm.. sorry, i think you didn't get the question.

I am not talking about the line number displayed on the lower right corner of IDE along with column number. I want to display each line number in the source code editor of the IDE.

In case of VS.NET, this option can be invoked from:

Tools->Options->Text Editor->C/C++->Line numbers

Just like to know whether it is possible with VC++ 6.0

Maybe it's a language barrier thing, but the line numbers I mentioned are shown in the editor. Confused | :confused:

They are, however, not on the left of the code which I think is what you are after.

This functionality does not exist with VC++ v6.

upon the following tutorials http://codeproject.com/miscctrl/#Colour+Selection+Controls[^]

and especially http://codeproject.com/miscctrl/colour_picker.asp[^]

and

http://codeproject.com/miscctrl/colourpickerxp.asp[^]

I could successfully use te classes, but I want to ask, upon these two articles, is the any way to get the value of the COLORREF and disploay it in a MessageBox or in an editbox using SetWindowText()

thanks in advance...

From MSDN:

When specifying an explicit RGB color, the COLORREF value has the following hexadecimal form: 

<code>0x00bbggrr </code>

The low-order byte contains a value for the relative intensity of red; the second byte contains a value for green; 
and the third byte contains a value for blue. The high-order byte must be zero. The maximum value for a single byte is 0xFF.

So just use masks to retrieve the colors:

COLORREF Color = ....;<br />
int BlueValue = Color&0x00FF0000;<br />
int GreenValue = Color&0x0000FF00;<br />
int RedValue = Color&0x000000FF;<br />
<br />
