Hi everyone,

I spend the whole night trying to make this work, but no luck! Maybe someone can help me out. I am literally pulling hairs out of my head.

I have the following SQL Stored procedure.

CREATE PROCEDURE UpdateTestVorgaenge
@TestName nVARCHAR(250),
@OutID int OUTPUT

AS
INSERT INTO Temp_TestVorgaenge_t (Name, Datum) values(@TestName, CURRENT_TIMESTAMP)
Select @OutID= @@IDENTITY

Now, I have a CRecordSet derived class and I want to use that to call this stored procedure.

here is what I do:

void DoFieldExchange(CFieldExchange* pFX)
{

pFX->SetFieldType(CFieldExchange::param);
RFX_Text(pFX, _T("TestName"), m_name);
pFX->SetFieldType(CFieldExchange::inoutParam);
RFX_Int(pFX, _T("OutID"), m_testVID);
}

And my Open statement looks like this...
CRecordset::Open(dynaset, _T("{CALL UpdateTestVorgaenge(?,?)}"), CRecordset::none);

But it throws an exception saying "Function Sequence error". Anyone has any ideas on how to make this work???

Thanks,

Sincerely yours,
Pankaj

Just guessing, but the second parameter is defined as an OUTPUT parameter, but in your c++ code, your setting the parameter as an 'inoutParam'.

Hi,

I have tried all sorts of combinations, but with no luck!...inout, outpurParam...
I think there must be something fundamentally wrong here. maybe it is not possible for record sets to return values...

Thanks,

I assume the stored procedure works if called through query analyzer?

Have you stepped into the Open function and found out which method is throwing the exception.

Is there any reason you are not using ADO. I find it much easier for calling stored procedures.

Hi,

Do not worry about it anymore. I am just going to use ExecuteSQL from CDatabase. Something really funky is happening with CRecordset. I think it is a problem when you use a stored procedure that does not return any records (like Insert or something). I am going to tackle this on a more relaxed day Big Grin | :-D

Thanks for the reply.

CScrollBar SB codes

I find that when I drag the thumbtrack to the extereme left, I step into the SB_THUMBPOSITION: case, not SB_LEFT. So what action do i have to take to make the SB_LEFT triggger?
After that I hope to figure out what makes SB_PAGELEFT trigger.
Thanks,
ns

case SB_THUMBPOSITION: // Scroll to absolute position. nPos is the position
    {
        m_nScrollPos = nPos;

        bRecalc = TRUE;

        break;
    }
case SB_LEFT: // Scroll to far left.
    {
        m_nScrollPos = minpos;

        bRecalc = TRUE;

        break;
    }

Are only some of your grid lines disappearing? if so:

StretchBlt works by removing columns and rows of pixels. It may be that some of the rows that StretchBlt removes are the rows (or columns) that contain your grid lines.

You could verify this by changing the destination DC dimensions in your StretchBlt call and see if different rows/columns end up disappearing.

Whenever I click it , there is a message window pop out.And it says "there is an unhandled exception 0xC0000005 of xxx.exe at 0x77f8910e happened . Reading address of 0x80000039 is error".Meanwhile , the frame stack stop at "NTDLL.DLL!77f8910e()".....Who , the kind people , could help me.

Where can I find an equivalent of HTMLEncode in Visual C++?
Something that would replace " by " etc... in a CString?
If there is nothing standard, I would be grateful if somebody would share his/her code.
Thanks in advance!

Please help me,what operation will cause buffer overrun?

My program has 4 threads .

And when it runs a few minutes ,error happens.

It prompted "buffer overrun detected! A buffer overrun has been detected which has corrupted the programs's interal state.The program cannot saftly continue execution and must now be terminated."

I use vc.net to compile it.The program base on SDI,CHtmlview.

when I use vc.6.0 compile ,the error isn't happen.

I don't know the difference about vc6.0 and vc.net.

Who can tell me what operation maybe cause this error happen?

Thanks !

The error may well happen on vc6.0, but the runtime is not geared up to detect it (which explains many of the security exploits that MS issue patches for).

You probably have a stack based variable (typically an array) that you're overwriting beyond the boundaries (char[] are favourites for this, many of the string functions don't/can't length-check)

Buffer overrun problems happen when data is written past a variables' alloted space. For example:

char str[10];
strcpy(str, "This is a very, very long line");

The compiler will not detect this, although some third-party debuggers will.

A number of recent exploits to Windows has been because of bugs like this.
