Have you handled the exceptions properly, especially during file handling?

Does your service create a log? Have you tried analysing the log for possible causes?

Hello,
I wnat to create my own child windows without document - view architecture.But I am facing problems in understanding fundamental theory relating CMDIFrameWnd, CMDIChildWnd and CView.Is there any article that can explain me the relations and how to go about it.

I made it in this way :

I derive my own Frame from CMDIChildWnd.
At the construction of this Frame i create the Initial-View with the function "CreateView"

So you don't want to use the Templates?
I also don't use the templates, but i have many troubles. Because if you don't
use the standard-MFC-Way you need to manage yourself all functionalities
( for example that the focus rests on the control if you switch to another application, ... )

So, i'm not really the best to explain you these things.
But if i can help you, i will do my best Wink | ;)

Hai..
I am developing VC++ application to write data to a pen drive.
Can any one help me how to proceed for it...
I want to move data of any type or complete folders into the pendrive without the help of driver..

Thanks in advance

when pen drive is connected to your system it is recongnized as a regular drive. So i think you can use standard api(for example CopyFile etc ) for writing data.

If u can Dream... U can do it

Are you working in embedded domain ?
Without any driver (USB ) i think it is not possible, u need to check the usb standards and write a simple driver.. Smile | :)

bitmap problem

Hi

i run into this code.. :

void CVidTestDlg::OnCapture()
{
CString Filter;
CString Filename;
CRect Rect;

Filter = "Bitmap Files (*.bmp)|*.bmp|AVI Files (*.avi)|*.avi||";

CFileDialog FileDlg(FALSE, "BMP", NULL,
OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
Filter,
this);

if (FileDlg.DoModal() == IDOK)
{
RedrawWindow();

Filename = FileDlg.GetPathName();

Capture(m_VFWImageProc, Filename);

m_VideoDisplay.GetWindowRect(Rect);
ScreenToClient(Rect);

m_VFWImageProc.EnablePreviewVideo(*this, Rect.TopLeft().x,Rect.TopLeft().y);
}
}

BOOL Capture(CVFWImageProcessor &ImageProc, LPCTSTR Filename)

{
ULONG Length = 0;
CFile File;
BOOL Ret = FALSE;
CHAR Ext[_MAX_EXT];

_splitpath(Filename,NULL,NULL,NULL,Ext);

if (stricmp(Ext,".avi") == 0)
{
Ret = ImageProc.CaptureAVI(Filename,4.0,10,10);
}
else if (stricmp(Ext,".bmp") == 0)
{
BITMAPINFO *Bitmap = NULL;
BITMAPFILEHEADER bfh;

ImageProc.CaptureDIB(&Bitmap,0,&Length);

if (Bitmap)
{
File.Open(Filename,CFile::modeCreate |
CFile::modeWrite |
CFile::shareDenyNone |
CFile::typeBinary);

bfh.bfType = 0x4d42; // 0x42 = "B" 0x4d = "M"
bfh.bfSize = (DWORD) Length + sizeof(BITMAPFILEHEADER);
bfh.bfOffBits = (DWORD) sizeof(BITMAPFILEHEADER) +
sizeof(BITMAPINFOHEADER) +
Bitmap->bmiHeader.biClrUsed * sizeof (RGBQUAD);
bfh.bfReserved1 = 0;
bfh.bfReserved2 = 0;

File.Write(&bfh,sizeof(bfh));
File.Write(Bitmap,Length);

File.Close();

Ret = TRUE;

delete Bitmap;
}

this is the code that is resposible for capturing a image from usb webcam and saving to hard driver

Function : CaptureDIB
Arguments : Bitmap (output) - Pointer to bitmap to receive image.
If *Bitmap = NULL, then allocation will
be performed automatically.
BitmapLength (input) - Size of Bitmap if *Bitmap is not NULL.
RetBitmapLength (output) - Actual size of image.
Return : TRUE Success, FALSE Failed.
Description: Captures a DIB image from video capture device.

As you see he uses some structs BITMAPINFO BITMAPFILEHEADER wihich togheter is the bitmap file. and writes it down to file.

now my problem...

i must make a dll wich exports symbols and a function within it , lets call it Capture that will return a bitmap (whole bitmap including header)

but i dont know how to copy the both struct within a buffer or something and return it.

can someone help. does someone get me..

sorry for bad explanation . i`m not champion at c++

downloading huge files

Can I download a file (like DirectX SDK) in chunks using CInternetSession/CHttpFile ? I built a program that downloads a whole file using CInternetSession/CHttpFile, but I can't do that whith huge files in just one session in dial-up connection. When I use CHttpFile::Seek(), the method returns immediately, but the subsequent CHttpFile::Read() takes as much time as reading from the beggining of the file. If not, is there another way to do it programmatically ?
