I am using CBitmapButton to display bitmap on the push button.

CBitmapButton m_bitmap;
m_bitmap.Create(NULL, WS_CHILD|WS_VISIBLE|BS_OWNERDRAW,
CRect(10,10,100,100), GetDc(), 1);
m_bitmap.LoadBitmap(IDB_PLAY,0,0,0);

This is not working

If you are in VC++ try with create the CBitmapButton in your resource editor, set the Bitmap there, and then when you make click on the button set the property to visible as you want.

If not...

With your code you are creating the bitmap and loading in the button but, are u sure that your GetDC () is pointing where you need?

Take a look step by step with the debugger

Simply start an unmanaged C++ project. Not a managed (CLR) one.
Use project type ATL, MFC or Win32.

You can get all the power of C++ and use MFC, qt, wxWidgets and WhatTheHeckElse as GUI Toolkit.

Windows forms are not possible - these are managed and require the installation of the .NET-Framework.
But you only need to install this once on a given PC. Like e.g. a Java VM.
Is this really a problem for you?

As others have side, yup you can create native C++ apps without the .NET runtime. However, when you go to distribute your apps you will need to ship the updated C runtime Microsoft Visual C++ 2005 Redistributable Package (x86)[^] for older computers

With respect, I must disagree. A quick look at middle management in just about any corporation shows that the dodo not only survived, it's reproducing in record numbers. Christopher Duncan

Which is 2,5 MB in size, only needed once per Computer, plus you can use the link to Microsoft (and don't have to ship it yourself).

You will only need to do that if you link dynamically to MFC / CRT. If you link statically (not the default settings, by the way), you don't have to distribute anything but your exe.

ODBC & C++ Question

Hi all,

I am using an ODBC class written by Carlos Antollini (A set of ODBC Classes) and making use of Oracle 10g Express Edition.
Basically what I'm trying to do, is perform a select statement on the database to determine if a certain
record exists. If the record exists I perform an UPDATE stament, and when the record doesn't exists,
I perform a INSERT. (I don't want to go the route of the Stored Procedures Thanks Smile | :)

)

For instance:

pdb.m_nRowsAffected=0;
pdb.Execute(SELECT * FROM TABLE WHERE FIELDNAME = 'CONDITION';);
if (pdb.m_nRowsAffected>0)
{
  UPDATE
}
else
{
  INSERT
}

THE PROBLEM:
The variable m_nRowsAffected returns a code of -1, even if the record exists. After stepping into the
function I saw that the SQLRowCount sets the variable to -1. I have no idea what is going on Confused | :confused:

. If I make
use of MySQL everything works. An example of the function Execute() is shown below. Can anyone please
assist me in this problem??

BOOL CODBCDatabase::Execute(CHAR *szSqlStr)
{
	SQLRETURN ret;
	SQLHSTMT hStmt = NULL;
	SQLINTEGER nRowCount;

	SQLAllocHandle(SQL_HANDLE_STMT, m_hDbc, &hStmt);
	ret = SQLExecDirect(hStmt, (SQLCHAR*)szSqlStr, SQL_NTS);
	
	SQLRowCount(hStmt, &nRowCount);
	
	m_nRowsAffected = nRowCount;
	return ret == SQL_SUCCESS || ret == SQL_SUCCESS_WITH_INFO;
}

Many Thanks

It's not really my topic but I did once write a SQL parser prototype based on the Oracle 8 SQL spec only to find that Oracle 8 SQL and 'normal' SQL disagree about a lot of things, especially SELECT cleverness. I'd check your Oracle docs for how to do this their way. I don't know if 10 is any more standards compliant than 8. Can you see what SQL the ODBC driver is producing and compare the MySQL output with the Oracle by any chance. That might help.

Nothing is exactly what it seems but everything with seems can be unpicked.

Well, I believe that doing a SELECT * is less optimal that doing a SELECT 1 because less data has to be processed/returned if you are just testing for the existance of something. That aside, I would try using SELECT 1 and maybe even an EXISTS test to return a rowset:

SELECT 1 FROM TABLE WHERE FIELDNAME = 'CONDITION'
 
SELECT 1 FROM TABLE WHERE EXISTS( SELECT * FROM TABLE WHERE FIELDNAME = 'CONDITION' )

I have had the unfortunate experience of working with multiple RDBMSes and you sometimes have to do something obscure like the above in order to make things works everywhere. If even the above calls fail, try executing the query within an EXEC statement (this is a problem I have had with Sybase RDBMSes).

Peace!

Can anybody help me in solving my problem.....

i am using a CFileDialog class for accessing multiple files through browse.But depending up on the file path length the number of files that are getting selected varied

Is there anyway in solving this problem(i need to select a maximum of 20 files).

CFileDialog fileDialog(true,null,null,OFN_MULTISELECT | OFN_NODEREFERNCELINK |OFN_EXPLORER ,"Excel File(*.xls)|*.xls|AllTypes(*.*)|*.*"); D'Oh! | :doh:

I htink you need to change the buffer size used for the returned filenames if the OFM struct:
It has to be large enough to contain all the full paths etc for all the files selected.

So you probably need _MAX_PATH * 20 in length:

<br />
    // copied and pasted from an app<br />
    char buffer[4096] = "";            // filename(s) buffer<br />
    dlg.m_ofn.nMaxFile = 4096;<br />
    dlg.m_ofn.lpstrFile = buffer;<br />

If you vote me down, my score will only get lower

POSITION file=fileDialog.GetStartPosition();

if(fileDialog.DoModal==IDOK) //this is where error is generating if i select more files... (for example 20)
{
UINT count=0;
POSITION pos=fileDialog.GetStartPosition();
while(pos)
{
fileDialog.GetNextPathPosition(pos);
++count;
}
while(file!=NULL)
{
fileName[count]=fileDialog.GetNextPathName(file);
