Use LOCALE_SLANGUAGE instead of LOCALE_IDEFAULTLANGUAGE. Your buffer will need to be a bit bigger too Wink | ;)

[edit] I used LOCALE_USER_DEFAULT instead of LOCALE_SYSTEM_DEFAULT so that it works if different users have different languages [/edit]

Hi all, please help me.
I am trying to load a bitmap using LoadImage . I have attach the code . Please create a bitmap of size 32*23 and save it to 256 colors.My Display pallette setting is in 16 million colors.

This is working fine in 256 color setting.

32*32 is the image width and image height.

OnDrawFunction()
{
typedef unsigned short UINT16;

UINT16 *MyDisplayBuffer = (UINT16*)GlobalAlloc(GPTR,32*32*2);

m_hBitmap = (HBITMAP)LoadImage(NULL,"C:\\Bitmap1.bmp", IMAGE_BITMAP, 0, 0,LR_LOADFROMFILE | LR_CREATEDIBSECTION | LR_DEFAULTSIZE);

CBitmap bmp;

bmp.Attach(m_hBitmap);

BYTE* DisplayBuffer=(BYTE*)GlobalAlloc(GPTR,32*32);

int Update = 0;

int color =0;

CDC memdc;

memdc.CreateCompatibleDC(pDC);

SelectObject( memdc,m_hBitmap);

bmp.GetBitmapBits(32*32,DisplayBuffer);

for(int y =0; y < 32; y++)
{
for(int x =0 ; x< 32; x++)
{
int index = x + y *32;

color= DisplayBuffer[Update];

MyDisplayBuffer[index] =color

Update++;
}
}

CDC dcDisplayMemory;

CBitmap bmp1;

dcDisplayMemory.CreateCompatibleDC(pDC);

bmp1.CreateCompatibleBitmap(pDC,32,32);

dcDisplayMemory.SelectObject(&bmp1);

bmp1.SetBitmapBits(32*32 *2,MyDisplayBuffer);

pDC->BitBlt(10,20,32,32,&dcDisplayMemory,0,0,SRCCOPY);
}

Thanks in Advance

This is a very long-winded way of doing it. Why don't you just do this:

HGDIOBJ hBitmap = LoadImage(NULL, _T("C:\\Bitmap1.bmp"), IMAGE_BITMAP,
      0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE);
CDC memDC;
memDC.CreateCompatibleDC(pDC);
HGDIOBJ hbmOld = SelectObject(memDC.m_hDC, hBitmap);
pDC->BitBlt(10, 20, 32, 32, &memDC, 0, 0, SRCCOPY);
SelectObject(memDC.m_hDC, hbmOld);
memDC.DeleteDC();

This should work nicely Smile | :)

Max array size?

Hi there

Tell me this is NOT true! How can the maximum array size only be 1035720 (0xfcdc8)?

Are you talking about static arrays or dynamic?

[EDIT]
Static arrays are limited by the size of the stack which is usually 4 MB (I think). Dymanic arrays are limited by the largest addressible block on the heap which is less than 2GB and depends on what addresses your program / dlls load at..

Static, but now I release I need a 64-bit PC DAMMIT!!!

I'm trying to do an analysis of a "transformation" to see how many instances of a unsigned int exists, hence the need for a "32-bit" sized array. I thought about going bitwise (just to get an off or on state) too, but still no luck.

O well back to the abacus/tickertape/punchcards/etc. And they say PC are Turing complete....(ok thats debatable, with hard work anything can be done).

How about a sparse array? I assume you will have no where near 4 GB of data?

I just need the "space" to see if what I am attempting to do is viable or not. In fact, the input is only 16bits.

CListCtrl - lost sel on postmsg DBLCLK

Looks like you're allocating an array on the stack. That probably won't work because the stack size is limited. To get an array that big you'll have to allocate the array dynamically.

With a simple CListBox I can SetCurSel() then from another routine

pWnd = GetDlgItem(IDC_LIST_BOX);
pWnd->PostMessage(WM_LBUTTONDBLCLK);

and in the handler for double click I can GetCurSel() and all is well.

If I get fancier with a CListCtrl (In Report style)
and programatically set a row to selected,

when I pWnd->PostMessage(WM_LBUTTONDBLCLK); to the ListCtrl

in the double click handler there is no longer a selected item

nItem = pMyListCtrl->GetNextItem(-1,LVNI_SELECTED); returns -1 but anytime before the
PostMessage() it is returning the correct selected row.

Anyone have a clue about this?

Re: CListCtrl - lost sel on postmsg DBLCLK

3-Jul-03 17:15

Sending a WM_LBUTTONDBLCLK like that won't do anything. This is because you haven't specified the position where the mouse is double clicked (look at the documentation for the WM_LBUTTONDBLCLK message). It appears to work for a list box, because a list box never removes the selection. If a click doesn't hit anything, it doesn't change the selection. However, for a list-view control, if a click doesn't hit anything, then the selection is removed, hence GetNextItem(-1,LVNI_SELECTED) returns -1.

Hope this helps,

Ryan

Thanks Ryan!

I've implemented the following and it is working great!
// Setup a post message with mouse x&y pointed to the selected item

pListCtrl =
(CListCtrl *)pThis->GetDlgItem(IDC_LIST_OPTION_SOURCES_REPORT);
pListCtrl->GetItemRect(pThis->m_OptionSourcesIdx,&rect,LVIR_BOUNDS);

lParam = MAKELPARAM(rect.left,rect.top);
pListCtrl->PostMessage(WM_LBUTTONDBLCLK,0,lParam);

I see you also were most helpful to others that night answering posts all night long! Great job - you efforts are most appreciated!

At the moment I'm trying to write an Office XP (specifically PowerPoint) add-in based on the excellent article by Amit Dey http://www.codeproject.com/com/outlookaddin.asp[^]

When I try to use the import directive to add MSO.DLL to the project I get the following linker error.

StdAfx.obj : fatal error LNK1179: invalid or corrupt file: duplicate comdat "_IID_CanvasShapes"

The build environment is VC6 SP5, with Office XP, SP1.

Any Ideas? Smile | :)

Hi,

I am developing an application with Visual C++ 6.0.

In the Visual C++ IDE, I can run my application in debug mode.

However, I can't run it in release mode.

How can I correct this behavior ?

Thanks,

Claude
