Re: Dialog Window supporting Database ???

Oh 4 that, you must have to add a member variable to the edit control say m_myname, and you must have to passon the value m_pSet->Name into this and must have to call updateData function

m_myname = m_pSet->Name
UpdateData(FALSE);

The best way is to write a function say getvalues(), which gets all the values from the recordset and displays it on the dialog.

I do think there is another way to bind direclty is there, but couldn't remember it. Just go throught the MSDN. Usually what i'll do is i'll write my own class 4 data manipulation

Thanks....this is one method that did not strike me....this can be done and i am sure it will work.

But usually what happens is that in the class wizard we get a combo box in which all the member variables are stored by default, we just have to choose for which resource which field variable we have to assign. In this case no coding is required.

But as you said i think by coding in this manner, the work will be done.

Anyways, Thanks a lot !!!

Hi! it's me again!!! I like to know how to store a image into a variable under MFC?

Eg. I declared a global variable with an array:

<br />
int n; <br />
n = (512-(Recty+1))*512 + Rectx; //equation<br />
int image512;<br />
image512[n];.......//how to store this image under another variable such as below//<br />
<br />
int dcmpixel [40] [40];<br />
<br />
int i, j;<br />
///got stuck here///<br />

I am not exactly sure whether it can be done or not, but even it can be done or not, what will you do by inserting a record in a recordset if you do not want to insert it in the database.

As far as my knowledge goes, the recordset is used as an interface between the user and the actual database, and once the connection is closed with the databse the recordset will not exist !!!

I know you can have disconnected recordsets in ADO. I think you do this by setting the ActiveConnection property of the Recordset to NULL. As far as inserting a record I would imagine it would work. Hope this helps.

Getting rid of C4005

When building for UNICODE, I'm getting a C4005 warning for a redefition of the UNICODE macro for each file in the project as each file includes stdafx.h, which in turn ultimately defines the macro.

Besides using a pragma to ignore the message, is there something else that I should be doing to build a UNICODE project without getting these warnings?

Cheers,

You could put the definition on the command line (-DUNICODE) rather than in stdafx.h.

I'm not putting it in stdafx.h. It's being defined somewhere down the line as a result of the project setting.

Sorry, i misread your question. What defines are specified on the command line? _UNICODE or UNICODE or both?

Have you tried defining just one of them? MFC/ATL uses _UNICODE but the windows headers use UNICODE, so afxv_w32.h and atldef.h have a section to synchronise them if they're not both set. They shouldn't define them if they're already defined, but might be doing so... The windows headers pdh.h and oledlg.h also do this synchronisation.

Hope this helps

Directdrawsurface gets lost???

I am trying to gradually blend a bitmap onto the primary surface, it works one time but when I try to do it again, the lpDDSBack.lpSurface is set to 0x000000,which it was not in the first execution!, and I am getting an exception error,

how could this be?

First I load the bitmap into the directdrawsurface lpDDSBitmap using the DDLoadBitmap function!

win* p;

typedef struct win
{
LPDIRECTDRAW lpDD;
LPDIRECTDRAWSURFACE lpDDSPrimary;
LPDIRECTDRAWSURFACE lpDDSBack;
LPDIRECTDRAWSURFACE lpDDSBitmap;
LPDIRECTDRAWCLIPPER lpClipper;
}

p->lpDDSBitmap=DDLoadBitmap(p,p->lpDD,L"crystalcocktail.bmp");

IDirectDrawSurface * DDLoadBitmap(win* p,IDirectDraw *pdd, LPCTSTR szBitmap)<br />
{<br />
    HBITMAP hbm;<br />
    BITMAP bm;<br />
    IDirectDrawSurface *pdds;<br />
<br />
   hbm=SHLoadDIBitmap(szBitmap);<br />
   if (hbm == NULL){<br />
           return NULL;<br />
  }<br />
<br />
    GetObject(hbm, sizeof(bm), &bm); // get size of bitmap<br />
<br />
   <br />
    // create a DirectDrawSurface for this bitmap<br />
      <br />
    pdds = CreateOffScreenSurface(pdd, bm.bmWidth, bm.bmHeight);<br />
        if (pdds) {<br />
        DDCopyBitmap(pdds, hbm, bm.bmWidth, bm.bmHeight);<br />
    }<br />
<br />
    DeleteObject(hbm);<br />
<br />
    return pdds;<br />
}

And then I Blit the bitmap surface to the Backbuffer using the Flip_Bitmap_To_Back(p):

bool_t Flip_Bitmap_To_Back(win* p)<br />
{<br />
    HRESULT ddrval;<br />
    RECT rcRectSrc;<br />
    RECT rcRectDest;<br />
    POINT pt;<br />
<br />
        // first we need to figure out where on the primary surface our window lives<br />
        pt.x = 0; pt.y = 0;<br />
        ClientToScreen(p->Wnd, &pt);<br />
        GetClientRect(p->Wnd, &rcRectDest);<br />
        OffsetRect(&rcRectDest, pt.x, pt.y);<br />
        SetRect(&rcRectSrc, 0, 0, 472, 286);   //var 472 286<br />
        ddrval =IDirectDrawSurface_Blt(p->lpDDSBack, &rcRectDest, p->lpDDSBitmap, &rcRectSrc, DDBLT_WAIT, NULL);<br />
        if(ddrval==DDERR_SURFACELOST){<br />
		   restoreAll(p);<br />
		}<br />
}

And then finally I uses the blendfunction

BltAlpha(p->lpDDSPrimary,p->lpDDSBack,0,0,&r,128,RGBMODE_565); //var RGBMODE_565
}

If I do this one more time the exception error occurs, and I don´t know why, could it be that the surface gets lost in some of the actions or?????

Please help me someone, thanks Dani

Hi,

I'm looking for a way to start out a standard C++ Console Application in full-screen. I know that once the app has started the user can press Alt+Enter, but it'd be really neat if I could figure out a way to get around that.

Anybody know of the code snippet to do something like that?

Thanks in advance for any help Smile | :)

I'm trying to use CxImage Library from codeproject..
But I realized that it is not so fast..

My favorite image viewer IrfanView shows really fast operation..
Which library do you think they use?

Which is the best FREE library?
ImageMagic? CxImage? GDI+?

I wish the library should be easy to use and FAST..

C++ is the pure standard language... (in theory).
now, each compiler can implement all (or more or less) of the grammar of the C++. that is the case of microsoft with its Visual suite.
Visual C++ that is compiled by the microsoft compiler contains specifics, that is why we commonly use this name to difference it from the others...

is that clear now ?
