program fails cause in ASSERT(m_pCtrlSite != NULL); "m_pCtrlSite" not an OLE control ?? will these two functions solve it and if so what's the directions or classes of them plz?

Very doubtful. Had you failed to initialize COM, the application would have most likely failed to even start.
I created a dialog-based project and added the Microsoft FlexGrid v6 Control to it. I then added the control to the dialog template. At this point, I could compile and run the application fine. What else do you have in place?

It would have started, but as soon as any access to the control was made, it would have given an assertion (in debug) or just crashed (in release).

True, in a sense.

Neither of which happened. It just went away quietly.

Hi,
I'm trying to debug my code, and each time I run into a dynamically-linked function-call, the debugger cannot step-into the function, and does not stop at breakpoints inside it.
e.g.
class ISender {
public:
virtual void Send() = 0;
};
class XSender : public ISender {
...
virtual void Send();
};
ISender *m_sender = new XSender;
m_sender->Send()
Instead, it suggests that it shows the disassembly, as if it cannot find the matching code. I've tried that, and I still can't go inside these functions.
Static calls to functions of the same class work properly, e.g.
ISender m_sender = new XSender;
In addition, The debugger does not show the value of the object in the monitor, unless I specifically cast it to the run-time type of the object, i.e.:
(XSender *)m_sender
I suspect that thesse problems are related but I'm not sure.
Any ideas Thanks.
while (i == live) {
have(fun);
}

Just a quick thing to check; you say the code's dynamically-linked (ie in a DLL); check the output pane of Visual Studio for the line that loads the DLL the call's in. It should say something like:
'StyleManager.exe': Loaded 'C:\Codebase\codedb\PF\Products\StyleManager\SMCmdLine\Debug\StyleManager.dll', Symbols loaded.
If it doesn't say 'Symbols loaded' for your DLL (instead it'll say 'No symbols loaded.'), then the debugger won't know how to debug into the DLL (other than in assembly view). You'll need to ensure that the DLL is built in debug mode and that the relevant PDB is around. Most of the time this happens automatically, but if you have a custom post-build step that copies the DLL somewhere else but not the PDB then you might get this kind of problem.

I have two bitmaps (loaded from resources).
I want to combine thse two bitmaps side-by-side into a 3rd bitmap.
I want to put the 3rd (combined) bitmap into an image list.
I tried using the BitmapDC class from the GDI articles section, but I'm missing something (obviously, otherwise I wouldn't be here).
Here's the code I'm using now:
CBitmap bmp1;
CBitmap bmp2;
bmp1.LoadBitmap(nImgConsult);
bmp2.LoadBitmap(nImgLabs);
CBitmapDC bmpDC(34, 21, GetDC(), RGB(255,255,255));
DrawBitmap(&bmp1, &bmpDC, CPoint(0, 0));
DrawBitmap(&bmp2, &bmpDC, CPoint(17, 0));
CBitmap* pBMP = bmpDC.Close();
if (!m_ResultsImages.Replace(0, pBMP, NULL))
{
TRACE("ImageList.Replace failed\n");
}
delete pBMP;
Any hints, clues, or alternative code?

Why not just use the GetBitmapBits/SetBitmapBits (and CGdiObject::GetObject) to get the bits from images 1 and 2, create a byte array that is the size of the sum of both those arrays (which should be double the size of either one if the bitmaps are the same size), copy the bytes from image 1 to the first part of the new array, and image 2 to the last part of the new array and then use SetBitmapBits on a newly created CBitmap object?

another approach is create a bitmap sized to fit both source bitmaps. arrange the bitmaps via bitblt()

Hi
Can we have two CDocument derived classes in an MDI application??
|

Thus the name MDI = Multiple Document

hey can anyone help me sort this? the weird thing is my program ran at first but now if i try and run i get this debug error!
*********************************************************************************************
*": warning C4267: 'argument' : conversion from 'size_t' to 'DWORD', possible loss of data"

Smells like an stl issue.
You will get this type of message if you do something like this:
<br />
std::vector<long> vecLong;<br />
int n = vecLong.size();<br />
A lot of the stl classes returns a size_t numeric data type (instead of say, int, long etc).
Its not an error, but you should be aware of any overflow issues. If you are sure that your DWORD variable has enough range to accomodate the stl's size_t number, then just do a simple type cast.
<br />
std::vector<long> vecLong;<br />
int n = static_cast<int>(vecLong.size());<br />

The compiler is telling you exactly what is wrong. Show the line of code in question.

this is not an error. it is just a warning.
the compiler warns you about the fact that you copy some value of a particuliar type into a smaller type, hence the "possible loss of data".
what you can do to avoid this is :
- make the two types identical
- explicitely cast while assigning the value
- disable temporarily/totally the warning using the #pragma warning(disable:4267) statment...

I believe you meant #pragma warning(disable:4267).

Are you compiling as 64-bit by chance? I believe size_t is a 64-bit integer on 64-bit platforms whereas DWORD (which is just an unsigned long) is always 32-bits. Thus, if you try to implicitly cast a size_t to a DWORD, it will give you that warning. To get around it, either ignore it, use bitshift operations to get the lower 32-bits, or use static_cast to explicitly cast it to a DWORD.

hi
i have funtion named change(long lngNo,unsigned char* pData);
where some times i send intger data,float data ,BOOL data as second parameter.How do i convert integer ,float ,BOOL to unsigned char*.
thanks in before

Use the address-of operator (&). For example:
int x;
change(5L, &x);

error C2664: : cannot convert parameter 2 from 'int *__w64 ' to 'unsigned char *'
|

You'll need to cast it, since change() is expecting an unsigned char *.
Why are you trying to make a one-size-fits-all function?

can't you write several overloads of the function, which every func receive the right type ?
