here is the question I did ask before:

I have a listview REPORT with fullrowselect style everything works fine, but after i used customdraw I faced a problem such pic included, it seems I click on the item col 3 it becomes bold and more bold..

Picture[^]

if i use listview_update the bold text from the col 3 will be gone so why happens? and i just want to click on the raw without having that bold problem? any ideas?

The Code

C++

if (lpNMHdr->code == NM_CUSTOMDRAW)
{
    LPNMLVCUSTOMDRAW lpCD = (LPNMLVCUSTOMDRAW)lpNMHdr;
    if (lpCD->nmcd.dwDrawStage == CDDS_PREPAINT)
    {
        return CDRF_NOTIFYITEMDRAW;
    }

    if (lpCD->nmcd.dwDrawStage == CDDS_ITEMPREPAINT)
    {
        return CDRF_NOTIFYSUBITEMDRAW;
    }

    if (lpCD->nmcd.dwDrawStage == (CDDS_ITEMPREPAINT|CDDS_SUBITEM))
    {
        if (lpCD->iSubItem == 0) //detect which subitem is being drawn
        {
            LPCTSTR lpcszBuf1 = _T("example");
            LPCTSTR lpcszBuf2 = _T("text");

            RECT iR = { 0 };
            ListView_GetSubItemRect(lpCD->nmcd.hdr.hwndFrom, lpCD->nmcd.dwItemSpec, lpCD->iSubItem, LVIR_BOUNDS, &iR);

            SetBkMode(lpCD->nmcd.hdc, TRANSPARENT);

            SIZE sz = { 0 };
            GetTextExtentPoint32(lpCD->nmcd.hdc, lpcszBuf1, 7, &sz);

            SetTextColor(lpCD->nmcd.hdc, RGB(255, 0, 0));                   
            DrawText(lpCD->nmcd.hdc, lpcszBuf1, -1, &iR, DT_LEFT);

            iR.left += sz.cx;

            SetTextColor(lpCD->nmcd.hdc, RGB(0, 255, 0));                   
            DrawText(lpCD->nmcd.hdc, lpcszBuf2, -1, &iR, DT_LEFT);                  

            return CDRF_SKIPDEFAULT;
        }
    }

So someone answered me:

If you draw it yourself you need to clear the background as well, which you are not doing. ~~Try using OPAQUE instead of TRANSPARENT.~~

However, I used OPAQUE but it does not help a lot so, I am trying now with clear the background: the message is wm_ERASEBACKGROUND but what I suppose to do? should I add the code there or what?

Just out of curiosity, why are you drawing the text yourself rather than using SetWindowText()?

I think either your X or Y coordinate is changing by 1 pixel each time. Without actually testing, that's just a guess, though.

Fair enough, but you can still use SetWindowText() (elsewhere, not in response to NM_CUSTOMDRAW) rather than DrawText() for that.

Check the X and Y coordinates to make sure they are the same each time your message handler is called.

You must fill the cell rect with the background color before drawing the text. The CDC class provides the FillSolidRect() function which can be used to do this. When using DC handles, you can do it the same way as the CDC class:

::SetBkColor(lpCD->nmcd.hdc, GetBkColor());
::ExtTextOut(lpCD->nmcd.hdc, 0, 0, ETO_OPAQUE, &iR, NULL, 0, NULL);

Thanks for this info..

You must fill the cell rect with the background color before drawing the text.

SetBkColor(lpCD->nmcd.hdc, GetBkColor());
ExtTextOut(lpCD->nmcd.hdc, 0, 0, ETO_OPAQUE, &iR, NULL, 0, NULL);

but may function looks like this

fillrect(); //i am using this to fill out the specific rect
settextcolor(); //then I set the text color
Drawtext() //then I draw the text

(1)
if use ExtTextOut then there is no need to drawtext?

ExtTextOut(lpCD->nmcd.hdc, 0, 0, ETO_OPAQUE, &iR, Buffer, strlen(Buffer), NULL);

(2)
i used SetBkColor(lpCD->nmcd.hdc, GetBkColor(..)); nothing happened, i do not set a bk color in my listview, i did set a row color manually... so If I do SetBkColor(lpCD->nmcd.hdc, RGB(255,0,0)); the whole list bk changed to red?

maybe the method i use is wrong..

My example code is those used by CDC::FillSolidRect(). It will erase the cell using the actual background color of the HDC which can be set to the default returned by CListView::GetBkColor() or any other you are specifying (e.g. a row specific color).

You may of course use ExtTextOut() to print the cell text parts with different colors when adjusting the rect.

When using CListView::SetBkColor() this will set the default color for the list. When calling ::SetBkColor(HDC), this specifies the color for the drawing functions using the HDC.

If you change the background color (or the text color) of the HDC, you should restore it to the original value that is returned by the first set call. Restoring the colors may be omitted when all cells are owner drawn.

error C2039: 'DebugString' : is not a member of '_DEBUG_EVENT'

I have not tried using direct drawing code such as you do, but maybe this MSDN sample[^] will help.

Hi

I am getting the above mentioned error when clearly DebugString is a member of _DEBUG_EVENT

My declaration of DEBUG_EVENT is as follows

C++

DEBUG_EVENT debug_event;

If you check the documentation for the structure[^] you will see that DebugString is part of the union u. So to address this item you should code:

C++

debug_event.u.DebugString;
// or depending on declaration
debug_event->u.DebugString;

Use the best guess

Hello,

I have a problem with my Progress Bar in MFC, C++

Indeed, I want display progress bar in CList Ctrl. I use the class CProgressCtrl.

And I want to move this prograss bar if my scroll bar move. I use MoveWindow(...), RedrawWindow(...) functions.

It runs in mode Debug but in mode Release, it doesn't run, i've got an error with MoveWindow function because in this function, the program doesn't know the m_Wnd and m_pCtrlSite

Help me

texture2D stretch

I want to record d3d games. Now I can get data from backbuffer and save it.

The programe is when the game resize the window, I should strech it.
The following is my steps:

C++

IRefPtr<ID3D10Texture2D> texture;
HRESULT hRes = m_pDXGISwapChain->GetBuffer(0, __uuidof(ID3D10Texture2D),
    reinterpret_cast<void**>(IREF_GETPPTR(texture,ID3D10Texture2D)));
if (FAILED(hRes))
{
    return hRes;
}


hRes = pDevice->CreateTexture2D(&desc, NULL, IREF_GETPPTR(textureDest,ID3D10Texture2D));
if (FAILED(hRes))
{
    return hRes;
}

pDevice->CopySubresourceRegion(textureDest, 0, 0, 0, 0, texture, 0, &sourceRegion);

Everything is ok, but as i say, when the game change size, i must stretch the Texture2D for get the whole picture. The CopySubresourceRegion() cant do it. And i dont find anyother way to do it.

Thanks for any advices. I am a newer for directx.

I am a rookie boy, if you help me, i will become a man.

hook game for d3d10 or d3d11

26-Jul-13 16:40

I think the D3D10LoadTexureformTexure() will be the right answer. But it is very slow.It is not a best answer but a right one.

Re: hook game for d3d10 or d3d11

18-Jul-13 16:36

Hi everyone.
Recently i'm working on a project which is to record games. Some trouble comes to me, for d3d10 and d3d11. I can hook the Present() through IDXGISwapChain:

PFN_D3D10_CREATE_DEVICE_AND_SWAP_CHAIN1 pDirect3DCreate10 = (PFN_D3D10_CREATE_DEVICE_AND_SWAP_CHAIN1)GetProcAddress("D3D10CreateDeviceAndSwapChain1");
if (pDirect3DCreate10 == NULL)
{
return false;
}

IDXGISwapChain * pSwapChain;
ID3D10Device1 * pDevice;
HRESULT hRet = pDirect3DCreate10(NULL, D3D10_DRIVER_TYPE_HARDWARE, NULL, 0, D3D10_FEATURE_LEVEL_9_1,
D3D10_1_SDK_VERSION, &swapChainDesc, &pSwapChain, &pDevice);
if (FAILED(hRet))
{
return false;
}

UINT_PTR* pVTable = (UINT_PTR*)(*((UINT_PTR*)pSwapChain));
m_nDX10_Present = pVTable[8];
m_nDX10_ResizeTarget = pVTable[14];

Using VTable to get the address. And I can save backbuffer. But when change game's size, the game will crash. It seems change size wouldn't go to ResizeTarget(). So I want to ask:
1. When the game change size for d3d10_1.dll, what does he do, and what should I do?
2. There is other question, when the game exit, what should i do. i want to stop my project when the game is exit.

Thanks for any advices. I'm a newer in directx. There are so many publishs for directx, i.e d3d9, d3dx9_43, d3d10, d3d10_1, d3d11, d3d11_1 and so on. D'Oh! | :doh:
