i used the wizard to create my app. it placed the following in my view to init the recordset.
m_pSet = &GetDocument()->m_tDSMSet;
CRecordView::OnInitialUpdate();
in my view header i have
class CTDSMSet;
.....
CTDSMSet* m_pSet;
i have been able to move the class declaration to my app header but nothing else with out errors. do you know if there is any documentation on moveing everything to the app class from a view class? or am i just looking to hard at this configuration maybe?

Always I prefer no use CRecordView, I prefer to declare de Database class and recordset in a public class for all classes in my application.... You need to see how can get access to the view from any dialog or other classes....
Try to get access to the View using AfxGetMainWnd();
Best Regards....

the MSDN said you can not DRAW in OnUpdate() function, which is called by OnInitialUpdate by default

who knows the answer , please tell me
thanks

You can draw, provided you can get a DC;
CClientDC dc(this);
However, there's a good chance that the window is not visible yet, so drawing into it will not be very useful. A better idea is to use the class as it was intended; initialize any data necessary for drawing in OnInitialUpdate(), updated it in OnUpdate(), and draw it in OnDraw(). OnDraw() will be called when the window is shown and first needs to be updated, so if you place your drawing code there, the view will act as desired.

i set a breakpoint in first line of the OnDraw
but can not trace into the code

Not sure what you mean now... The break point isn't getting hit?

BC 4.5 uses BWCC.dll (16-bit one). Use Target to switch to 32-bit one OR rebuild Your broject by C++ Builder.

Subject :- Isn't there native support for PNG in Windows?
I've requoted my subject.
Christian and other GDI gurus...
This shocked me quite a bit.
I checked out the bitmap section on CP.
There are several classes available to display PNG files.
But I thought I should start from scratch and try and show a PNG first before I try to manipulate it.

Isn't there native support for PNG in Windows?
Using Win32 API? No.
You can probably work around this by fiddling with COM objects the Internet Explorer pollutes your system with, or you can use e.g. libpng [libpng.org]

What's so special about PNG anyway?
What's wrong with JPG,BMP,GIF???
Why do people want PNG all of a sudden?

JPG is complex and lossy.
BMP is basically a raw bit-dump, and as such the most bloated format you could use for off-line storage.
GIF is limited by evil patents.
PNG has no patent issues, has lossless compression and is just free.
Why do people want PNG all of a sudden?
All of a sudden? Well, one of the reasons could be that it has been a W3C standard (or was that "just" a recommendation?) for quite a few years now.

Thanks for all that info.
The fact is right now I am in a sort of anti-PNG attitude for some personal-job-related reasons

I dunno about png ( although a lot of people put it forward as a replacement for gif ), but Unisys own the patent to the compression used in gif, so any code that uses gif requires payment of royalties. That is what killed gif online.

No (not directly in the Win32 SDK, GDI, or MFC), but there is in GDI+...

not entirely true... the latest BITMAPINFOHEADER specs include the option of a PNG or JPG encoded data in addition to the old formats.

You are correct... For the in-memory representation of the images, but for loading and saving of PNG (or JPEG for that matter) files? My guess is that is what the OP meant by "native support": the ability to easily load and save a PNG file just as easily as calling "::LoadImage( <pathtobmpfile> ):.
I know that ImportImage(...) does, but that requires an add-on (DirectX/DirectAnimation) to Windows.
Peace!

Hi I would like to know if anybody can help me out here.
I want to create a transparent Image By Performing all operation on a Memory dc.
This Is what I have done so far and it works ..The only problem is that I do not know how to initialise the Bitmap which is selected into the memory DC
My current code is as folllows..
DrawTrans(CDC* pDC, COLORREF crColor)
{
COLORREF m_crWhite = RGB(255,255,255);
COLORREF m_crBlack = 0;
COLORREF crOldBack = pDC->SetBkColor(m_crWhite);
COLORREF crOldText = pDC->SetTextColor(m_crBlack);
COLORREF crOldBkMode = pDC->SetBkMode(TRANSPARENT);
// Create two memory dcs for the image and the mask
CDC dcTrans, dcImage;
CDC dcFinal;
CBitmap bmpFinal;
bmpFinal.CreateCompatibleBitmap(pDC,ImageWidth, nImageHeight);
dcFinal.CreateCompatibleDC(pDC);
dcImage.CreateCompatibleDC(pDC);
dcTrans.CreateCompatibleDC(pDC);
//m_PImageInfoData is structure contaiing
BITMAPINFO bmpInfo;
/*char* */ BYTE* pszData;
int nImageWidth = m_pImageInfoData->bmpInfo.bmiHeader.biWidth;
int nImageHeight = m_pImageInfoData->bmpInfo.bmiHeader.biHeight;
int nUsage = DIB_RGB_COLORS;
// Create the mask bitmap
CBitmap bitmapTrans, bitmapImage;
bitmapImage.CreateCompatibleBitmap(pDC, ImageWidth, nImageHeight);
bitmapTrans.CreateBitmap(nImageWidth, nImageHeight, 1, 1, NULL);
CBitmap* pOldBitmapImage = dcImage.SelectObject(&bitmapImage);
// Select the mask bitmap into the appropriate dc
CBitmap* pOldBitmapTrans = dcTrans.SelectObject(&bitmapTrans);
CBitmap *pOldBmp = dcFinal.SelectObject(&bmpFinal);
StretchDIBits(dcImage.GetSafeHdc(), 0, 0, nImageWidth, nImageHeight, 0, 0, nImageWidth, nImageHeight, m_pImageInfoData->pszData,
&(m_pImageInfoData->bmpInfo),
DIB_RGB_COLORS, SRCCOPY);
dcImage.SetBkColor(crColor);
// Build mask based on transparent colour
dcTrans.BitBlt(0, 0, nImageWidth, nImageHeight,
&dcImage,
0, 0, SRCCOPY);
dcFinal.StretchBlt(0, 0, nImageWidth, nImageHeight,
&dcImage,
0, 0,
nImageWidth, nImageHeight, SRCINVERT);
dcFinal.StretchBlt(0, 0, nImageWidth, nImageHeight,
&dcTrans,
0, 0, nImageWidth, nImageHeight,
SRCAND);
dcFinal.StretchBlt(0, 0, nImageWidth, nImageHeight,
&dcImage,
0, 0,
nImageWidth, nImageHeight,
SRCINVERT);
pDC->StretchBlt(0, 0, nImageWidth, nImageHeight,
&dcImage,
0, 0,
nImageWidth, nImageHeight,
SRCCOPY);
// Restore settings
dcTrans.SelectObject(pOldBitmapTrans);
dcImage.SelectObject(pOldBitmapImage);
dcFinal.SelectObject(pOldBmp);
bitmapTrans.DeleteObject();
bitmapImage.DeleteObject();
bmpFinal.DeleteObject();
pDC->SetBkMode(crOldBkMode);
pDC->SetTextColor(crOldText);
pDC->SetBkColor(crOldBack);
dcFinal.DeleteDC();
dcTrans.DeleteDC();
dcImage.DeleteDC();
This code works perfectly fine except for the garbage values that are displayed bcoz the Bitmap is not initialized...I would like to know what i can do to initialse the bitmap to NULL ...
Thanks ...
