还有一个教程小问题~ 范例程序 -> 彩色图片转换为底片效果-> for(int i = pimg->getwidth() * pimg->getheight(); i >= 0; i--) 其中pimg->getwidth() * pimg->getheight()会越界，忘记了-1

教程中的一个报错。技术文章-> 学习保存应用程序的配置信息-> if (sqrt((msg.x - x) * (msg.x - x) + (msg.y - y) * (msg.y - y)) < R) 其中的sqrt 有报错：对重载函数的调用不明确。

一个关于TransparentBlt的问题. 同样是获得绘图窗口的HDC 为什么以下这种获得的，就可以不用加FlushBatchDraw();就能把图片显示出来。 # include <graphics.h> # include <conio.h> #pragma comment(lib, "msimg32.lib") #pragma comment(lib, "Winmm.lib") int main(void) { initgraph(200, 200); IMAGE img; loadimage(&img, _T("dunpai.bmp"));//自己修改以下 HWND hwnd = GetHWnd(); HDC hdc = GetDC(hwnd); //GetWorkingImage(); //HDC hdc = GetImageHDC(); HDCsrcDC = GetImageHDC(&img); TransparentBlt(hdc,0,0, 28, 28, srcDC, 0, 0, 28, 28, RGB(100,100,100)); // 使显存生效（注：操作指向 IMAGE 的显存不需要这条语句） //FlushBatchDraw(); getch(); return 0; }

yangw80求助啊~~~帮我调试一下这个。。。就是以下地址：pan.baidu.com/s/19UZyy （坦克2）———— pan.baidu.com/s/1GaDnB （坦克1）的这两个坦克（坦克1的dsw文件运行后按A玩不起。坦克2的dsw文件运行后按A玩得起），你是不是也是这样，你看看问题出在哪了？我整了很久了实在没办法了。。谢谢你了

如何传递二维数组呢？？？这样不行~~~~~~~~~~~~~~~~！我希望在子函数仍然可以p[][]这样的使用数组 # include <stdio.h> void b(int * p) { for (int i=0; i<5; i++) for (int j=0; j<5; j++) printf("%d", p[i][j]); } int main(void) { int a[5][5] = {1, 2, 3, 4, 5,1, 2, 3, 4, 5,1, 2, 3, 4, 5}; b(a); return 0; }

找色第三个问题~~~~~~~~~~~~~~ 这次仅仅限制了while（l<3）只循环3次发现按Y后鼠标并不会移过去。但改成while（l<5）只循环5次按Y后鼠标就会移过去。也就是说找之前找3遍都没找到色必须找5遍以上才行。为什么？ # include <graphics.h> # include <stdio.h> int start(void); void Quit(void); void CaptureDesktop(IMAGE *pimg) {int w = GetSystemMetrics(SM_CXSCREEN) ; int h = GetSystemMetrics(SM_CYSCREEN) ; Resize(pimg, w, h);HDC aa = GetDC(NULL); HDC dstDC = GetImageHDC(pimg); BitBlt(dstDC, 0, 0, w, h, aa, 0, 0, SRCCOPY);} int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {COLORREF cr;cr = start(); initgraph(200,60); TCHAR s2[20]; sprintf(s2, _T("%#x"), cr); TCHAR s1[30]="已确定你要找的颜色值为："; outtextxy(0, 0, s1); outtextxy(0, 20, s2); TCHAR s[30]="按Y键开始找色,按B键退出"; outtextxy(0, 40, s); int w = GetSystemMetrics(SM_CXSCREEN) ; int h = GetSystemMetrics(SM_CYSCREEN) ; while (true){if (GetAsyncKeyState('Y')) {closegraph();break;}Quit();} int l=0; while (l<3) { l++; IMAGE img; CaptureDesktop(&img); saveimage(_T("f:\\testq1.bmp"), &img); /*initgraph(640, 480);putimage(0, 0, &img);*/ loadimage(&img, "f:\\testq1.bmp"); DWORD* p = GetImageBuffer(&img); POINT point;for(int i = 0; i < w * h; i++) if (p[i] == BGR(cr) ){point.y = i / (w * 1.0); point.x = i - point.y * w ;Sleep(100); SetCursorPos(point.x, point.y);break;} DeleteFile("f:\\testq1.bmp");Quit();}return 0;} int start(void){initgraph(150,80); HDC hdc = GetDC(NULL);COLORREF cr; POINT point;TCHAR s[20];TCHAR s1[20]="横坐标:";TCHAR s2[20]="纵坐标:"; TCHAR s3[20]="颜色值:"; TCHAR s4[30]="按A键确定,按B键退出"; while(true){GetCursorPos(&point); sprintf(s, _T("%05d"), point.x); outtextxy(0, 0, s1);outtextxy(55, 0, s); sprintf(s, _T("%05d"), point.y);outtextxy(0, 20, s2); outtextxy(55, 20, s);Sleep(10); cr = GetPixel(hdc, point.x, point.y); sprintf(s, _T("%#x"), cr);outtextxy(0, 40, s3); outtextxy(55, 40, s);outtextxy(0, 60, s4); if (GetAsyncKeyState('A')){closegraph();ReleaseDC(NULL,hdc);return cr;}Quit();}} void Quit(void){if(GetAsyncKeyState('B')) {if(MessageBox(NULL, "你确定要退出吗？","提示", MB_YESNO) == IDYES) exit(0);}return ;}

找色第二个问题~~~~~~~~~~~~~~~~~~~~~~~ 这次仅仅去掉了saveimage(_T("f:\\testq1.bmp"), &img);loadimage(&img, "f:\\testq1.bmp");程序就识别不了这个img 就找不到色，就是按Y 后没反应了。 —————————————————————————— # include <graphics.h> # include <stdio.h> int start(void); void Quit(void); void CaptureDesktop(IMAGE *pimg) {int w = GetSystemMetrics(SM_CXSCREEN) ; int h = GetSystemMetrics(SM_CYSCREEN) ; Resize(pimg, w, h);HDC aa = GetDC(NULL); HDC dstDC = GetImageHDC(pimg); BitBlt(dstDC, 0, 0, w, h, aa, 0, 0, SRCCOPY);} int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {COLORREF cr;cr = start(); initgraph(200,60); TCHAR s2[20]; sprintf(s2, _T("%#x"), cr); TCHAR s1[30]="已确定你要找的颜色值为："; outtextxy(0, 0, s1); outtextxy(0, 20, s2); TCHAR s[30]="按Y键开始找色,按B键退出"; outtextxy(0, 40, s); int w = GetSystemMetrics(SM_CXSCREEN) ; int h = GetSystemMetrics(SM_CYSCREEN) ; while (true){if (GetAsyncKeyState('Y')) {closegraph();break;}Quit();} while (true) {IMAGE img; CaptureDesktop(&img); /*initgraph(640, 480);putimage(0, 0, &img);*/ DWORD* p = GetImageBuffer(&img); POINT point;for(int i = 0; i < w * h; i++) if (p[i] == BGR(cr) ){point.y = i / (w * 1.0); point.x = i - point.y * w ;Sleep(100); SetCursorPos(point.x, point.y);break;} DeleteFile("f:\\testq1.bmp");Quit();}return 0;} int start(void){initgraph(150,80); HDC hdc = GetDC(NULL);COLORREF cr; POINT point;TCHAR s[20];TCHAR s1[20]="横坐标:";TCHAR s2[20]="纵坐标:"; TCHAR s3[20]="颜色值:"; TCHAR s4[30]="按A键确定,按B键退出"; while(true){GetCursorPos(&point); sprintf(s, _T("%05d"), point.x); outtextxy(0, 0, s1);outtextxy(55, 0, s); sprintf(s, _T("%05d"), point.y);outtextxy(0, 20, s2); outtextxy(55, 20, s);Sleep(10); cr = GetPixel(hdc, point.x, point.y); sprintf(s, _T("%#x"), cr);outtextxy(0, 40, s3); outtextxy(55, 40, s);outtextxy(0, 60, s4); if (GetAsyncKeyState('A')){closegraph();ReleaseDC(NULL,hdc);return cr;}Quit();}} void Quit(void){if(GetAsyncKeyState('B')) {if(MessageBox(NULL, "你确定要退出吗？","提示", MB_YESNO) == IDYES) exit(0);}return ;}

简单的侵蚀病毒~~~~ 慎！！！！把 while（）里改成 true或1 死循环就ok了~！！！！ ———————————————————————— 电脑配置不行的最好别运行这个程序~~ 我i7电脑都卡的要死~ # include <graphics.h> # include <conio.h> # include <stdio.h> int main(void) {int i = 0; int w = GetSystemMetrics(SM_CXSCREEN) ; int h = GetSystemMetrics(SM_CYSCREEN) ; Sleep(2000); HDC hDC=GetDC(NULL); while (i < 50000) {SetPixel(hDC,rand() % w, rand() % h,GREEN);i++;}ReleaseDC(NULL,hDC); return 0;}

功能软件连点器~~ # include <windows.h> # include <conio.h> # include <stdio.h> int j = 0; void Quit(void); void start(void); int main(void){ int i = 0;while (true) {printf("按一下B点击鼠标左键1000次"); start(); while (i < 1000) {mouse_event (MOUSEEVENTF_LEFTDOWN |MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 ); i++;}i = 0; printf("已点完1000次，继续");} return 0;} void start(void) {printf("\n按B开始,已完成%d次\n\n",j++); while (true){if (getch() == 'b'||getch() == 'B')break; }return ;}

模仿按键精灵找色~！用这个程序用来启动某个游戏很好~ —————————————————— 程序是：在窗口内找到随机出现的红点并把鼠标移过去。在程序运行的瞬间请不要移动鼠标否则会破坏效果。红点只有一个像素，要仔细看。 —————————————————— # include <graphics.h> # include <conio.h> # include <time.h> int main(void) {int cx = GetSystemMetrics(SM_CXFIXEDFRAME); int cy = GetSystemMetrics(SM_CYFIXEDFRAME) + GetSystemMetrics(SM_CYCAPTION); initgraph(640,480); HWND hwnd = GetHWnd(); DWORD* p = GetImageBuffer(); POINT point;srand( (unsigned)time( NULL ) ); putpixel(rand() % 640, rand() % 480 ,RED); RECT rect;for(int i = 0; i < 640 * 480; i++) if (p[i] == BGR(RED) ) {point.y = i / (640 * 1.0); point.x = i - point.y * 640 ; GetWindowRect(hwnd,&rect); SetCursorPos(cx + rect.left + point.x, cy + rect.top + point.y); } getch(); return 0;} 可以多运行几次试试效果。

花了3小时，编了一个非常简单的贪吃蛇。在暑假以前都玩别人的游戏于是自学了6天的c语言和easyx，自己做了第一个小贪吃蛇游戏。
