C++ Calling Out Arguments inside the Functions and its funcion it'self

[KYAW KYAW OO]

I would like to get the value of argument and its output from function as per below.

LPCWSTR fileName = _T("C\\Test.bmp"); 
unsigned char *Content, Mem;
HBITMAP bitmap;

bitmap = LoadBMPFromFile(fileName, Content);
Mem = Content;

HBITMAP Dlg::LoadBMPFromFile(LPCWSTR fileName, unsigned char *Content)
{
      HBITMAP hBitmap = (HBITMAP)LoadImage(NULL, fileName,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE);

   BITMAP m_sbmpBitmap;
   CBitmap m_bmpBitmap;

    datasize = m_bmpBitmap.GetBitmapBits(datasize * sizeof(COLORREF), lpClrData);

    for(int i = 0;i<m_sbmpBitmap.bmHeight;i++)
    {
          for(int k = 0;k<m_sbmpBitmap.bmWidth;k++)
          {
                  char *Mem = temp.put(k,i, 3);
            }
   }

    Content = (unsigned char*)Mem;
    return hBitmap;
}

Please advise me to get it done since I left this function only for my development and looking forward to hearing from good news from someone.

can you post the code in code format

at the top of the code
LPCWSTR fileName = _T("C\\Test.bmp ");
the given path is wrong in that case your program will try to find the file
"dir_of_the_exec utable\c\Test.b mp"

but I guess you are trying to pu
C:\Test.bmp

Hi,

Here is my draft code and I think one input argument and mulitple output arguments couldn't be possible using C++ funcitons.

// main.cpp 
BOOL Dlg::Start()
{ 
     LPCWSTR fileName = _T("C\\Test.bmp");      // same as C:\Test.bmp 
     unsigned char *Content, Mem; 
     HBITMAP bitmap; 
  
     bitmap = LoadBMPFromFile(fileName, Content); 
     Mem = Content; 

     // display image from Mem
    
}
  
HBITMAP Dlg::LoadBMPFromFile(LPCWSTR fileName) 
{ 
      HBITMAP hBitmap = (HBITMAP)LoadImage(NULL, fileName,IMAGE_BITMAP,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE); 
  
   BITMAP m_sbmpBitmap; 
   CBitmap m_bmpBitmap; 
  
    datasize = m_bmpBitmap.GetBitmapBits(datasize * sizeof(COLORREF), lpClrData); 
  
    for(int i = 0;i<m_sbmpBitmap.bmHeight;i++) 
    { 
          for(int k = 0;k<m_sbmpBitmap.bmWidth;k++) 
          { 
                  char *Mem = temp.put(k,i, 3); 
            } 
   } 
  
    Content = (unsigned char*)Mem; 
    return hBitmap; 
}

// main.h
// Image Display and BufferMemory
typedef struct Image
{
	 HBITMAP hBitmap;
	 unsigned char *bufMem;
}Image;

I would like to return HBITMAP and unsigned char* from the function LoadBMPFromFile to main.cpp. I am trying with structure to settle this issue and hoping from someone's advice soon.

Best regards

KYAW KYAW OO,

please start posting your code inside [code]...[/code] tags. It makes it easier to read. This is the second time I have asked you to do this if you continue breaking forum posting guidelines you will begin getting infractions, if you get enough infractions you will get an initially temporary ban from the forum.
