I think this way is good
#include AtlImage.h
CImage m_Image;
m_Image.Load("c:\\picture.bmp");
//m_Image.BitBlt(GetDC()->m_hDC,CRect(0,0,800,600),CPoint(0,0));
m_Image.StretchBlt(GetDC()->m_hDC,CRect(0,0,200,200),CRect(0,0,800,600));

Hi ewighell,
There are some steps of doing this:
[1] Load the bmp in mem. Your can use CBitmap::Load to do this. the CBitmap class can give you a handle (HBITMAP) to this bitmap.
[2] Create a dc by using CDC::CreateCompatibleDC; select the bmp handle into this dc (CDC::SelectObject).
[3] Override the dialog's OnPaint function. use CDC::Bitblt or CDC::StretchBlt to render the bmp on to dialog surface.
Regards,
Chris

The error means what it says, you're trying to pass too few parameters to a function. Not wanting to be rude, but that shouldn't be hard to work out.

Well, I would suggest that if you've taken a course that is above your level you can either drop out, or work really hard to catch up.

This error occurs when number of parameters in function declaration do not match with number of parameters you are passing at the time of function calling. So check your function declaration.
Good luck

The easy solution is not to run your program.
Not tryng to be rude, but how the hell did you get a programming job?

Hi all,
I am trying to instantiate a dialog box and keep getting the error message
'too few parameters, expected 2'
the offending piece of code is:
void CFisheriesView::OnAlmforeignkeys() {
COpenDB open; //ok
open.ALM(); //ok
CALMFKeyDlg dlg; //bombs out here
dlg.DoModal();
}
Anyone can give me some pointers? Thx,
Ralf.

Hi RalfPeter,
I guess your dialog class is derived from CDialog. Is that right?
If you create a mfc dialog application, use default settings and just go 'finish' to create the code, you may find the following piece of codes in your ...Dlg.cpp file:
<br />
CtestmfcDlg::CtestmfcDlg(CWnd* pParent )<br />
: CDialog(CtestmfcDlg::IDD, pParent)<br />
{<br />
m_hIcon = AfxGetApp()->LoadIcon(IDR_MAINFRAME);<br />
}<br />
Here you can see that the CDialog class actually need two or one parameter to initialize. You need to do this in your code as well.
The IDD is a id to a dialog resource. you can create a new dialog resource by using 'add' option in the drop down menu of the resource explorer window.
Regards,
Chris

It looks like the constructor expects arguments. ie.
CALMFKeyDlg dlg(something_here, and_something_here);
You'll have to look at the definition of CALMFKeyDlg::CALMFKeyDlg to see what it expects.

Should you be able to create your own mfc42.dll from the MFC/SRC source files (plus whatever else is available to the VC++ developer)? I'd like to put some breakpoints in MFC code to debug a release-only problem.

No, you can't. Your release only problem is probably a problem with memory that you're not initialising properly, debug mode does it for you. The best way to check that stuff is to write logging code in your exe and read the log after running it.

A release-only problem screams uninitialized variable, or a pointer problem. I use TRACE statements.

i wanna get the device information from the registry and take it as parameter to connect to the particular bluetooth device.
I manage to get the service information but not device infomation.
Below is the code:
/////////////////////////////////////////////////////////////////////
typedef struct _BT_DEVICE /* BT Device structure */
{
BD_ADDRESS bdAddress; //Address of the devcie
UINT8 pageScanRepetitionMode; //Page scan repetetion mode
UINT8 pageScanPeriodMode; //Page scan period mode

UINT16 serviceClass; //Service class field
UINT8 majorDeviceClass; //Device class(Major) feild
UINT8 minorDeviceClass; //Device class(Minor) feild
UINT8 clockOffset[2]; //Clock offset
}BT_DEVICE, *PBT_DEVICE;
////////////////////////////////////////////////////////////////////

if(BT_IsInitialized())
{
if(BT_Open())
{
int count = 0;

{
DWORD dwIndex = 0;
TCHAR tcKeyName[512];
DWORD dwcbName = 512 * sizeof( TCHAR );
FILETIME ftLastWrite;

//

AfxMessageBox(_T("Got service"));

AfxMessageBox(_T("No service"));

*/
}
else
AfxMessageBox(_T("Open Register fail"));
retResult = TRUE;
}
else
AfxMessageBox(_T("BT not yet open!"));
}
else
{
AfxMessageBox(_T("BT not yet initialized!"));
BT_Init();
SPPConnectToSerialPort();
}
sdpHandle = SDAP_GetConnection(&device1);
sppConnection = SPP_Connect(&device1, &service, &frameSize, NULL,portName);
if(sppConnection == NULL)
{
AfxMessageBox(_T("Finally SPP Not connect"));
}
else
{
AfxMessageBox(_T("Finally SPP connect"));
}
I fail to get the device1 info from the method above.
Another question, how could I put the define for the path REMOTE_BLUETOOTH_DEVICE_SETTING which is always vary?
Please give me any comment or suggestion on this.
Thanks

I need help coming up with code that can teach students how to make change.
Students enter a price while computing a 5.6% sales tax also. The program will allow the student to enter the amount of change, as well as how many $20's,$10, $1, quarters nickels, and pennies to return to the customer.
 If someone could help me (as im am learning the basics) with that i just need help on how to change the amuont the customer paid to an integer, or all cents, so that all the calcualtions will b with integers.

Am I right in thinking that when you say 'students', it means you're running a class, but you can't write this yourself ?
To make a double an int, use the floor function in math.h. To get the floating point bit, you could always subtract the int from the full value. There may also be a function that does this ( I am answering under the influence of jetlag, and I don't remember one right now )
