Re: Drawing a bitmap on DC created by BYTE* array - C / C++ / MFC Discussion Boards

There is a MFC wrapper around the Win32 FindFirstFile/FindNextFile called CFileFind. Look it up on MSDN:
http://msdn.microsoft.com/en-us/library/f33e1618(VS.80).aspx[^]

There is also a small example which will do exactly what you need.

In addition to the other answer... Once you have the name of the file, you pass it to a string and use something like:

szExtension = szFileName.Right(szFileName.ReverseFind('.'));
if ((szExtension == "bku") || (szExtension == "sdb") || (szExtension == "wdb"))
    Do whatever you want to do with the files that you are looking for

Hope it helps

This is exactly what I needed. I was not even aware it was part of MFC. Thank you very, very much. it works perfectly. Thanks.

A C++ programming language novice, but striving to learn

I wrote the following lines in order to draw a bitamp on DC created by BYTE* array:

#define BPP 32

// Initialize the bitmapinfo header
int nBitmapInfoSize = sizeof(BITMAPINFOHEADER) ;
memset(&m_bitmapInfo, 0, m_nBitmapInfoSize);

// Save size for drawing later.
int nBitPP = BPP / 8;
int nImageWidth = nWidth;
int nImageHeight = nHeight;
int nImageSize = nImageWidth * nImageHeight * nBitPP;

// Allocate memory for byte array and initialize it
BYTE* pbtImageArray = new BYTE [nImageSize];
memset(m_pbtImageArray, 0x0000, nImageSize);

for (int i = 0; i < nImageSize - nBitPP; i+=nBitPP)
{
pbtImageArray[i] = 0x0000;
pbtImageArray[i+1] = 0x0000;
pbtImageArray[i+2] = 255;
pbtImageArray[i+3] = 0x0000;

}

// Populate bitmapinfo header
BITMAPINFO bitmapInfo; // Bitmap info
bitmapInfo.bmiHeader.biSize = nBitmapInfoSize;
bitmapInfo.bmiHeader.biWidth = nImageWidth;
bitmapInfo.bmiHeader.biHeight = nImageHeight;
bitmapInfo.bmiHeader.biPlanes = 1;
bitmapInfo.bmiHeader.biBitCount = BPP;
bitmapInfo.bmiHeader.biSizeImage = nImageSize;
bitmapInfo.bmiHeader.biCompression = BI_RGB;

// Create bitamp
HBITMAP hbmp = CreateDIBSection( pCDC->GetSafeHdc(),
&bitmapInfo,
DIB_RGB_COLORS,
(void**)pbtImageArray,
NULL,
0);

HDC hBitmapDC = CreateCompatibleDC(pCDC->GetSafeHdc() );

HBITMAP hOldBitmap = (HBITMAP)SelectObject(hBitmapDC, hbmp);

StretchBlt( pCDC->GetSafeHdc(), nWindowX, nWindowY, nWindowWidth,
nWindowHeight, // Destination
hBitmapDC , nRegionX, nRegionY, nRegionWidth,
nRegionHeight, // Source
SRCCOPY);

SelectObject(m_hBitmapDC, hOldBitmap);

Do you know why this draw black image and not my BYTE* array?

Thanks! Rose | [Rose]

When doing this type of drawing for the first time and getting errors, you should check your return values, especially for CreateDIBSection. This can indicate where the problem occurs. I would also provide values for all the fields in the BITMAPINFO header structure. I'm assuming that all the other variables that you didn't explain, are correctly initialized values of some MFC class that you are using, and that the values are correct.
I don't use MFC, but you might read this: Drawing a View[^]
The article states: "A device context is a Windows data structure that contains information about the drawing attributes of a device such as a display or a printer. All drawing calls are made through a device-context object. For drawing on the screen, OnDraw is passed a CPaintDC object. For drawing on a printer, it is passed a CDC object set up for the current printer."

Mostly your order is wrong, you do not need to allocate the byte array, CreateDIBSection does that for you, the pbtImageArray pointer you are passing in is the output, not the input

So more along the lines of

#define BPP 32
int nBitPP = BPP / 8;
int nImageWidth = nWidth;
int nImageHeight = nHeight;
int nImageSize = nImageWidth * nImageHeight * nBitPP;

// Populate bitmapinfo header
BITMAPINFO bitmapInfo; // Bitmap info
bitmapInfo.bmiHeader.biSize = nBitmapInfoSize;
bitmapInfo.bmiHeader.biWidth = nImageWidth; 
bitmapInfo.bmiHeader.biHeight = nImageHeight;
bitmapInfo.bmiHeader.biPlanes = 1;
bitmapInfo.bmiHeader.biBitCount = BPP;
bitmapInfo.bmiHeader.biSizeImage = nImageSize;
bitmapInfo.bmiHeader.biCompression = BI_RGB;

// Create dib
BYTE* pbtImageArray = NULL;
HBITMAP hbmp = CreateDIBSection( pCDC->GetSafeHdc(), &bitmapInfo, DIB_RGB_COLORS, (void**)&pbtImageArray, NULL, 0);

//Then fill in the data.
for (int i = 0; i < nImageSize - nBitPP; i+=nBitPP)
{
     pbtImageArray[i] = 0x0000;
     pbtImageArray[i+1] = 0x0000;
     pbtImageArray[i+2] = 255;
     pbtImageArray[i+3] = 0x0000;
}
HDC hBitmapDC = CreateCompatibleDC(pCDC->GetSafeHdc() );

HBITMAP hOldBitmap = (HBITMAP)SelectObject(hBitmapDC, hbmp);

StretchBlt( pCDC->GetSafeHdc(), 
            nWindowX, nWindowY, 
            nWindowWidth, nWindowHeight, // Destination 
            hBitmapDC , 
            nRegionX, nRegionY, 
            nRegionWidth, nRegionHeight, // Source
            SRCCOPY);

SelectObject(m_hBitmapDC, hOldBitmap);

Thanks! You are right, pbtImageArray is OUTPUT and not input.

I change it to void* pbtImageArray and add:

m_pbtImageArray = (BYTE*)pbtImageArray;

As for the previuse reply:

1) Off course at my original code I add nResult and do all the checks!!!
2) I add initialization for all variables at bitmapinfo.

Thanks you both! Laugh | :laugh:

i am using a chart control in my application to plot data.. i can comfortably plot the data but it is taking a long time to plot. how do i optimise the data so that i can plot in a lesser duration. now its taking alomost 6 to 8 mins to plot one data.

i am trying to read line by line now. what are the other ways to get the data?? please give me some leads.

thanks

Maybe with a bit more info or some code snippet... There can be different reasons for that.

We are trying to read Non-Ole File Properties (eg office 2007) using dsofile.dll. We can easily read properties of both Ole(doc file 97,2003) and non-ole(office 2007) using dsofile.dll(com dll). We did not use dsofile com dll because it has to be registered and take reference in the calling C# project. Actually we re-wrote our own dll using visual c++.net. The main interface for reading ole file property is IStoragePropertySet object. Here is the code snippets

// If the file is an OLE Storage DocFile...
if(StgIsStorageFile(m_bstrFileName)==S_OK)
{
IStorage *pStorage = NULL;
IPropertySetStorage *pPropSetStg = NULL;
HRESULT hr;

// Open the document as an OLE compound document.
hr = ::StgOpenStorage(wcFilename, NULL,
STGM_READ | STGM_SHARE_EXCLUSIVE, NULL, 0, &pStorage);
}
else
{
//How to get non-ole file properties
}

As I showed the code snippets, there is no problem in getting ole-file properties. What we are struck in is getting non-ole file property.

Here is the code snippets from the original source code of dsofile com dll.

// If the file is an OLE Storage DocFile...
    if (StgIsStorageFile(m_bstrFileName) == S_OK)
    {
     // Get the data from IStorage...
	    hr = StgOpenStorage(m_bstrFileName, NULL, dwOpenMode, NULL, 0, &m_pStorage);

     // If we failed to gain write access, try to just read access if caller allows
	 // it. This function will open the OLE file in transacted read mode, which
	 // covers cases where the file is in use or is on a read-only share. We can't
	 // save after the open so we force the read-only flag on...
        if (((hr == STG_E_ACCESSDENIED) || (hr == STG_E_SHAREVIOLATION)) && 
            (m_dwFlags & dsoOptionOpenReadOnlyIfNoWriteAccess))
        {
            m_fReadOnly = TRUE;
	        hr = StgOpenStorage(m_bstrFileName, NULL, 
				(STGM_READ | STGM_TRANSACTED | STGM_SHARE_DENY_NONE), NULL, 0, &m_pStorage);
        }
        
	 // If we are lucky, we have a storage to read from, so ask OLE to open the 
	 // associated property set for the file and return the IPSS iface...
	    if (SUCCEEDED(hr))
        {
            hr = m_pStorage->QueryInterface(IID_IPropertySetStorage, (void**)&m_pPropSetStg);
        }
    }
    else if ((m_dwFlags & dsoOptionOnlyOpenOLEFiles) != dsoOptionOnlyOpenOLEFiles)
    {
	 // If caller would like non-OLE property sets, we can try to provide them. There
	 // are two types: (1) explicit metadata handlers registered by file type; or (2) 
	 // NTFS 5.0+ property stream data in NTFS file header (which is actually saved as
	 // alternate stream). The former is custom provider to save data inside the file 
	 // without using OLE. The later is available for any file on NTFS5 disk.
		CLSID clsidMetaHandler = {0};
		IPersistFile *prtsf = NULL;

		if (DsoGetMetaHandler(m_bstrFileName, &clsidMetaHandler) == S_OK)
		{

			hr = CoCreateInstance(clsidMetaHandler, NULL, CLSCTX_INPROC, IID_IPersistFile, (void**)&prtsf);

					hr = prtsf->QueryInterface(IID_IPropertySetStorage, (void**)&m_pPropSetStg);
					if (SUCCEEDED(hr)){ASSIGN_INTERFACE(m_pPrstFile, prtsf);}
				}
				prtsf->Release();	
			}
			else hr = DSO_E_NODOCUMENTPROPS; // bad news, unable to load handler.
		}
		else if (v_pfnStgOpenStorageEx)
		{
		 // On Win2K+ we can try and open plain files on NTFS 5.0 drive and get 
		 // the NTFS version of OLE properties (saved in alt stream)...
			hr = (v_pfnStgOpenStorageEx)(m_bstrFileName, dwOpenMode, STGFMT_FILE, 0, NULL, 0, 
					IID_IPropertySetStorage, (void**)&m_pPropSetStg);

		 // If we failed to gain write access, try to just read access if caller
		 // wants us to. This only works for access block, not share violations...
		   if ((hr == STG_E_ACCESSDENIED) && (!m_fReadOnly) &&

			{
				m_fReadOnly = TRUE;

We successfully converted the code in italic ie for ole file. We are trying to convert code in bold ie for non-ole but we are not yet success. What we are trying to do is
to read the non-ole file properties using dll instead of com dll(ie dsofile.dll).

We are very much eager to hear you genius guys.

Thank You

Prakash Tandukar

for non- ole file types we have to get pointer of IID_IPropertySetStorage rather than istorage and the rest will be the same.
only problme here is we cant update office 2007 file type as the file structure of office 2007 file type is bit different.
if you fine any solution for accessing office 2007 do let me know.

hi

i create an activex with Visual c++6(mfc) and called its property in a vc sample.
i add one new property to AxtiveX but when i run my sample get "invalid number of parameters" error message.
i didnt any change in old property and just add new property with class wizard but get this error.
please help me

Can you put a bit of code where the error is coming? I guess that if you didn't change anything but you add a new property it is maybe missing something when you call/create your control.

Is it possible for me to use GetControlUnkown() function of CWnd in a static library built with the option of not using MFC

Look in the MFC source code and see how it implements that function. MFC is, at its heart, a wrapper for the Win32 API.

If you don't say you have already searched we can not adivinate it.

By the way, in that results there are articles that use some things that you will need to make what you want. Just to explain all is a bit large to be done at once. Take a look on the articles, make tests and ask when you have problem in one section. You will easily get the help asking something concrete that you can't solve that something with so much information to be given as your first post.

Take a look into the articles 2,3 and 4 of the search results I gave you. Make a screenshot can be more or less the same as getting the bitmap of the desktop.

Hello everyone,

I need for my program to store some results (recordings) into a database and then to access or search that recordings from/in DB.
I searched on Msdn but didn't find a concrete example. Has anyone an explicit easy to understand example?

I need to store: file names, size, last time modified, if readonly and other things.

the program is something like:

int main( void )
{
struct _finddata_t c_file;
intptr_t hFile;

// Find first .c file in current directory
if( (hFile = _findfirst( "*.c", &c_file )) == -1L )
printf( "No *.c files in current directory!\n" );
else
{
printf( "Listing of .c files\n\n" );
printf( "RDO HID SYS ARC FILE DATE %25c SIZE\n", ' ' );
printf( "--- --- --- --- ---- ---- %25c ----\n", ' ' );
do {
char buffer[30];
printf( ( c_file.attrib & _A_RDONLY ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_SYSTEM ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_HIDDEN ) ? " Y " : " N " );
printf( ( c_file.attrib & _A_ARCH ) ? " Y " : " N " );
ctime_s( buffer, _countof(buffer), &c_file.time_write );
printf( " %-12s %.24s %9ld\n", c_file.name, buffer, c_file.size );
} while( _findnext( hFile, &c_file ) == 0 );
_findclose( hFile );
}
}

Thanks very much!
