I want to save a 24 bit bitmap's RGB data as a file.I firstly import it to resource editor. void CReadView::OnDraw(CDC* pDC) { CReadDoc* pDoc = GetDocument(); ASSERT_VALID(pDoc); // TODO: add draw code for native data here int i,j; int counter=0; BYTE data[640*480*3]; CBitmap bmp; bmp.LoadBitmap(IDB_BITMAP1); bmp.GetBitmapBits(640*480*3,data); BITMAP bitmap; bmp.GetBitmap(&bitmap); for(i=0;i<bitmap.bmHeight;i++) for(j=0;j<bitmap.bmWidth;j++) { pDC->SetPixel(j,i, RGB(data[counter],data[counter+1],data[counter+2])); counter+=3; } } The result is not correct.:confused:

Thank you very much.The problem has been solved. :rose: :)

I am going to be crazy..X| The problem still haven't been solved. UINT BulletGo(LPVOID pParam) { CBullet* bullet=(CBullet*)pParam; while(TRUE) { switch(bullet->GetDirection()) { case UP: bullet->GoUp(); break; case DOWN: bullet->GoDown(); break; case LEFT: bullet->GoLeft(); break; case RIGHT: bullet->GoRight(); break; } if(!bullet->m_bCanGo) break; else bullet->MoveWindow(bullet->GetPosition().x,bullet->GetPosition().y, bullet->GetThisRect().Height(),bullet->GetThisRect().Width()); Sleep(30); } return 0; } BOOL CBullet::GoDown() { if(m_rtParent.bottom==0) GetParent()->GetClientRect(&m_rtParent); if((m_ptPosition.y+m_rtThis.Height())<m_rtParent.bottom) { m_ptPosition.y+=6; m_bCanGo=TRUE; return TRUE; } else { m_bCreated=FALSE; m_bCanGo=FALSE; while( ::WaitForSingleObject(m_pThread->m_hThread,1) == WAIT_TIMEOUT) { Sleep(1); } delete m_pThread; this->DestroyWindow(); return FALSE; } } I destroy the window after ending the thread. Is the judgement: ::WaitForSingleObject(m_pThread->m_hThread,1) == WAIT_TIMEOUT right?If it is right,where is the problem.. :((

I have found the error:I can't end the thread after destorying the window,right? ;P

I set a breakpoint on "return 0" in the thread function.When the bullet hit the bottom of client rect,the appliction jump to the breakpoint,and I step over,the debugger doesn't pop up error dialog until execute to the line AfxEndThread(nResult) in function UINT APIENTRY _AfxThreadEntry(void* pParam). How do you think the two methods of conrol the enemies and bullets that one use threads and the other use timer in class?Which waste more CPU resource?

Mmmm...I think if I draw the 'entities' with DC,I think the application would take large CPU resource,so I do it in thread.And I think using thread to control the enemies and the bullets easier. I will try you advice, thank you~

Thank you for you advice.But it helps nothing to the problem... :sigh:

The application pops up a dialog about error saying that Debug Assertion Failed! Program : D:\Code\TankGame\Debug\TankGame.exe File : wincore.cpp Line : 304 ......

I am doing a TankGame program,and I write a CBullet class.I write a thread function to make it move when it is created: UINT BulletGo(LPVOID pParam) { CBullet* bullet=(CBullet*)pParam; while(TRUE) { switch(bullet->m_bCanGo.GetDirection()) { case UP: bullet->GoUp(); break; case DOWN: bullet->GoDown(); break; case LEFT: bullet->GoLeft(); break; case RIGHT: bullet->GoRight(); break; } if(!bullet->m_bCanGo) break; else bullet->MoveWindow(bullet->GetPosition().x, bullet->GetPosition().y, bullet->GetThisRect().Height(), bullet->GetThisRec().Width()); Sleep(30); } return 0; } int CBullet::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CStatic::OnCreate(lpCreateStruct) == -1) return -1; m_bCanGo=TRUE; m_pThread=AfxBeginThread(BulletGo,this); //begin thread return 0; } BOOL CBullet::GoDown() { if((m_ptPosition.y+m_rtThis.Height())>m_rtParent.bottom) { m_ptPosition.y+=2; m_bCanGo=TRUE; return TRUE; } else { this->DestroyWindow(); m_bCreated=FALSE; m_bCanGo=FALSE; return FALSE; } } When the bullet go down and hit the bottom of client rect the program apprear errors.Why...Don't the "break" in the BulletGo() end the thread?

I am doing a program which is BattleTank Game(I believe most people here have played it before:)).I want to ask that how the maps are impremented?How to do with the tile when I shoot bullets to the it? Appreciating your hints~

The computer I am using havn't been installed MSDN.I want to know that how to use CreatePolygonRgn(CONST POINT*,int,int).Could somebody send the information about the function in MSDN?Thank you. And is the function PtInRgn exist?I want to use the both function to judge if a point in a polygon region. Thanks for your help.

But the area is not a regular one... X|

But the section was selected by the mouse,so the section is not a rect.

Yes,I want to cut the section I select from the image.

In Windows' Drawing Tool,there is a funtion that is we can select the discretioal part of the image.How can it realize? Have I make a clear expression?;P I appreciate your hint.

Hoho..Thanks a lot.What John said amazing me just now.:-D

Where can I download msdn?What I downloaded can't be setup at all..:(( Thanks~

I am not so familiar with GDI+,so I don't know that the code your provided can wheather achieve my purpose definitely.What I mean is the region in the bitmap is not necessarily a rect,it is mainly region that I draw with mouse.So it is a irregular region.Could you get it?;P

I want to cut a bitmap and save the selection I cut what is anomalistic under GDI+.Is there any program that I can refer to? Thanks.

Thanks,my English is not good enough,but I will work hard to improve it.:) Do someone know that in China there are many technologies for curing short sight,such as through looking at light in different frequency,tradional Chinese Medicine,but not effective to everybody.So I want to know that is there any new technologies for curing short sight.;)
