Did you include the required header file ?
|
|
|
|
|
Yes sir,
#pragma once
#include "xmllite.h"
class CXMLWriter
{
public:
CXMLWriter();
virtual ~CXMLWriter();
protected:
CComPtr<istream> pOutFileStream;
};
</istream>

Did you try to include atlbase.h ?
|
|
|
|
|
It's work sir, so what is the problem in my code.
I found that IStream need to include objidl.h and I try it give the same error. There is no any details regrading the atlbase.h
Can you advice me on this.
I appreciate your help all the time...

The compiler was complaining that CComPtr was not defined, so I just googled for it and found this page[^] (first result). If you look at the requirements section, it says which header file you have to include.
So, whenever you have such kind of error, the easiest thing to do is just google to see which files need to be included.

Get the pointer of Menu using GetMenu api, than extract teh particular menu by using GetSubMenu api, and on pointer of returned Menu class as the new button!

IN A DAY, WHEN YOU DON'T COME ACROSS ANY PROBLEMS - YOU CAN BE SURE THAT YOU ARE TRAVELLING IN A WRONG PATH

Hello and good day. I have 2 applications wherein I want the 1st which creates a graph send its image to the 2nd which will display it. I searched for some ways and ended up using a MFC shared DLL wherein I have a HBITMAP which the 1st one will write image on, and the 2nd one will read (using WM_COPYDATA for signalling, and mutex for synch). It's declared as the ff:
#pragma bss_seg("MFCDLLSample")
TESTDLL_API HBITMAP DLLImageBmp;
#pragma bss_seg()
Now, I checked first if it works by having the 1st app make a graph then display it on another picture box (same app) and it actually worked. When I tried to display it in the 2nd, it does not display. I coded it like this in the 2nd app:
PicWnd = GetDlgItem(IDC_PICBOX);
PicDC = PicWnd->GetDC();
oldBmp = (HBITMAP)PicDC->SelectObject(DLLImageBmp);
PicPaintDC.BitBlt(0, 0, 404, 404, PicDC, 0, 0, SRCCOPY);
CDialog::OnPaint();
Can anyone help me out with this? I really need to know what might be wrong with my code or implementation.
Thank you in advance for the help and time!
--added contents:
I forgot, TESTDLL_API's definition is this:
#ifdef TESTDLL_EXPORTS
#define TESTDLL_API __declspec(dllexport)
#else
#define TESTDLL_API __declspec(dllimport)
#endif
Thanks again!

GDI handles cannot be shared across process.
You have to think of some alternative methods to transfer the image from the first process to next. A possible method is sending the pixel data of the bitmap to the second process and the second process should recreate the bitmap using the pixel data.
1) you can use GetDIBits() function to get the pixel data of a bitmap
2) use WM_COPYDATA or other interprocess communication methods to send the pixel data to the second process.
3. use CreateDIBitmap() function to recreate the bitmap.

Yes, but if it was shared through DLL, its still not possible?  I was adviced last time to do that. Please refer to this link[^].

I am also confused seeing that.
AFAIK, it cannot be shared.
From MSDN:
"GDI objects support only one handle per object. Handles to GDI objects are private to a process. That is, only the process that created the GDI object can use the object handle"
The GDI handles are actually offset to the handle map's that reside in the client side. So when you pass a handle to another process, it simply points to a location in the handle table in that process. Some times, the object in that location will be entirly a different one such as Brush or Pen or some times the object itself is not created. So the result will be unpredictable.
if you want to know more please read the article Give Me a Handle, and I'll Show You an Object[^]

Guess I trusted that advice too early, even though I had a doubt in my mind if it was possible in the first place.
Anyway, I'll read the article to have more knowledge on this and try coding the solution that you gave me earlier on. Thank you very much for your help and time!
