MapLogicScreenToUserScreen这个函数需要译成DELPHI
BOOL WINAPI MapLogicScreenToUserScreen(RECT *rcLogic,
RECT *rcUser,
CAP_WND_POS *pCardPos,
DWORD dwCardCount);
说明： 设置Overlay屏幕区域到用户屏幕区域的映射关系。
系统初始化时创建了一个同屏幕大小一致的Overlay屏幕区域，
我们称之为逻辑屏幕区域，用户屏幕区域则是指我们所看到
的实际屏幕区域。StartOverlay函数中传入的矩形参数实际上
是在逻辑屏幕区域的绝对位置，由于系统初始化时两区域的
1：1关系，所以我们可以得到同坐标同大小用户屏幕区域的
视频图像。利用此函数则可重建此映射关系，以改变图像大
小/位置等比例关系。
参数： rcLogic：
Overlay逻辑屏幕区域指针，NULL表示整个逻辑屏幕
区域(此时等同于用户屏幕区域)
RcUser：用户屏幕区域指针，为NULL表示整个用户屏幕区域。
pCardPos：结构数组指针，NULL表示重置所有窗口。详见下述结构说明。
DwCardCount： pCardPos结构数组的成员个数。
返回值：TRUE： 成功
FALSE： 失败.
结 构：typedef struct tagCardRect
{
DWORD dwCard; //卡号
RECT rcUser; //新的用户屏幕区域位置
}CAP_WND_POS;

例： 我们在逻辑屏幕上相临区域创建了四路(卡)视频输出，
如左图小区域0 1 2 3 所示，如在通常1：1映射方式下工作，
这四路输出将显示到用户屏幕的左下同坐标区域，大小不变，
现在我们改变映射关系，将此逻辑区域映射到全屏，则用户得到
视频图像输出如右图所示。此时，rcLogic参数应传入整个4路输
出所占用区域在逻辑屏幕中的矩形坐标，而RcUser参数则可传入NULL值,
对于pCardPos参数，由于此时重新映射后的用户屏幕区域包含4路输出，
此时DwCardCount参数应为4，再将其卡号和他们在用户屏幕区域对应的
新矩形坐标传入即可。

现在最主要的是第三个及第四个参数压入时有问题，现附上VC的相关代码
void CSdk2500Dlg::SetScreenThirdToOne(RECT rc)
{
RECT m_rc[6];
int iCards = 4;

MapLogicScreenToUserScreen(NULL,NULL,NULL,0);

ZeroMemory(m_rc,sizeof(RECT) * 6);

//make the x,y
int i,l1,l2,xb,yb,xs,ys,xStart,yStart,xLen,yLen;
double bix,biy;

bix = 0.75;
biy = 0.6;

xLen = (int)((rc.right - rc.left) * bix) ;
yLen = (int)((rc.bottom - rc.top) * biy) ;

l1 = 2;//xLen * 0.01;
l2 = 2;//yLen * 0.01;

xb = int(xLen * 0.7);
yb = yLen - (2 * l2);
xs = xLen - xb - l1;
ys = (yLen - (4 * l2))/3;

xStart = rc.left ;
yStart = rc.top;
//so we have the x,y
m_rc[0].left = xStart;
m_rc[0].top = yStart + l2;
m_rc[0].right =xStart + xb;
m_rc[0].bottom=yStart + yLen - l2;

m_rc[1].left = xStart + xb + l1;
m_rc[1].top = yStart + l2;
m_rc[1].right = xStart + xLen;
m_rc[1].bottom= yStart + ys + l2;

m_rc[2].left = xStart + xb + l1;
m_rc[2].top = yStart + ys + (2*l2);
m_rc[2].right = xStart + xLen;
m_rc[2].bottom= yStart + ((2 * ys) + (2 * l2));

m_rc[3].left = xStart + xb + l1;
m_rc[3].top = yStart + (2 * ys) + (3 * l2);
m_rc[3].right = xStart + xLen;
m_rc[3].bottom= yStart + yLen - l2;

for(i=0;i<iCards;++i)
{
m_pButton.MoveWindow(&amp;m_rc,TRUE);
}

for(i=0;i<iCards;++i)
{
StartOverlay(i,m_pButton.m_hWnd,&amp;m_rc);
//新增函数,将TRUE该为FALSE即可屏蔽用户双击
EnableRespondDbClk(i,FALSE);
}

//Map to all the video screen
RECT rcLogic,rcDest;

rcLogic.left = m_rc[0].left;
rcLogic.top = m_rc[0].top;
rcLogic.right = m_rc[3].right;
rcLogic.bottom = m_rc[3].bottom;

rcDest.left = rc.left ;
rcDest.top = rc.top ;
rcDest.right = rc.right ;
rcDest.bottom = rc.bottom ;

CAP_WND_POS *CardPos = new CAP_WND_POS[4];

//下面的计算稍繁，暂时没有其他更好的办法
CardPos[0].dwCard = 0;
CardPos[0].rcUser.left = rc.left;
CardPos[0].rcUser.top = rc.top;
CardPos[0].rcUser.right = rc.left + 410;
CardPos[0].rcUser.bottom = rc.bottom;

CardPos[1].dwCard = 1;
CardPos[1].rcUser.left = rc.left + 412;
CardPos[1].rcUser.top = rc.top;
CardPos[1].rcUser.right = rc.right;
CardPos[1].rcUser.bottom = rc.top + 128;

CardPos[2].dwCard = 2;
CardPos[2].rcUser.left = rc.left + 412;
CardPos[2].rcUser.top = rc.top + 130;
CardPos[2].rcUser.right = rc.right;
CardPos[2].rcUser.bottom = rc.top + 256;

CardPos[3].dwCard = 3;
CardPos[3].rcUser.left = rc.left + 412;
CardPos[3].rcUser.top = rc.top + 260;
CardPos[3].rcUser.right = rc.right;
CardPos[3].rcUser.bottom = rc.bottom;

BOOL ret = MapLogicScreenToUserScreen(&amp;rcLogic,&amp;rcDest,CardPos,4);

delete CardPos;
}
 
BOOL WINAPI MapLogicScreenToUserScreen(RECT *rcLogic,
RECT *rcUser,
CAP_WND_POS *pCardPos,
DWORD dwCardCount);
function MapLogicScreenToUserScreen(var rcLogic,rcUser:TRect;
pCardPos:PCAP_WND_POS; //可能类型是PPoint=^TPoint;
dwCardCount:DWORD):BOOL;stdcall;
 
刚才不好意思，没看清楚，哪个结构应该如下：
typedef struct tagCardRect
{
DWORD dwCard; //卡号
RECT rcUser; //新的用户屏幕区域位置
}CAP_WND_POS;
tagCardRect=record
dwCard:DWORD;
rcUser:TRECT;
end;
CAP_WND_POS=tagCardRect;
PCAP_WND_P0S=^CAP_WND_POS;
 
如何使用，你直接调用就可以，填充几个结构而已，和DELPHI的差不多
 
你是哪里有问题，是SetScreenThirdToOne函数译成Delphi代码以后不对还是MapLogicScreenToUserScreen
函数译成Delphi代码以后不对？要帮你译哪一个？
 
var
ret:BOOL;
rcLogic,rcDest:TRect;
CardPos:PCAP_WND_P0S;
这样调用
ret = MapLogicScreenToUserScreen(rcLogic,rcDest,CardPos,4);
 
MapLogicScreenToUserScreen这个函数不对只需要这个函数就行了。
其它的函数暂不需要。
这个函数总是译不对。
我的译法如下：
TtagCardRect=record
dwCard:longWord; //卡号
rcUser:Trect; //新的用户屏幕区域位置
end;
PTRect=^TRect;
PTagCardRect=^TtagCardRect;
PArrTagCardRect=array of PTagCardRect;


TCallMapLogicScreenToUserScreen=function(
LogicRect:PTRect;
rcUser:PTRect;
var pCardPos:array of TTagCardRect
//pCardPos:PTagCardRect
;dwCardNum:LongWord
):Boolean;
最主要是第三个参数怎么样才能正确的压入的问题。上面的VC程序给出了调用函数的
原型第三个参数据在DELHP中需要怎么样定义才能正确的压入。
请写出整个调用函数的代码I
 
var
ret:BOOL;
rcLogic,rcDest:TRect;
PHeader,CardPos:PCAP_WND_P0S;
这样调用
CardPos:=AllocMem(SizeOf(CAP_WND_POS)*3);
PHeader:=CardPos;
try
for i:=1 to 3 do
begin
CardPos^.// 设置他的值
Inc(CardPos,SizeOf(CAP_WND_POS));
end;
ret = MapLogicScreenToUserScreen(rcLogic,rcDest,PHeader,4);
finally
freemem(CardPos);
end;
//这样绝对没有问题
 
定义
TtagCardRect=record
dwCard:longWord; //卡号
rcUser:Trect; //新的用户屏幕区域位置
end;
PTRect=^TRect;
PTagCardRect=^TtagCardRect;
PArrTagCardRect=array of PTagCardRect;

CAP_WND_POS=TtagCardRect;
PCAP_WND_P0S=^CAP_WND_POS;

声明函数类
TCallMapLogicScreenToUserScreen=function(
LogicRect:PTRect;
rcUser:PTRect;
pCardPos:PCAP_WND_P0S
//pCardPos:PTagCardRect
;dwCardNum:LongWord
):Boolean;

声明函数
function CallMapLogicScreenToUserScreen(
{Var LogicRect:TRect;
var rcUser:Trect;
pCardPos:PTagCardRect
;dwCardNum:LongWord
):Boolean; }

LogicRect:PTRect;
rcUser:PTRect;
pCardPos:PCAP_WND_P0S
;dwCardNum:LongWord

function CallMapLogicScreenToUserScreen(
{ Var LogicRect:TRect;
var rcUser:Trect;
pCardPos:PTagCardRect
;dwCardNum:LongWord

函数据调用

CallSetVideoProValue(dwCard,VideoProperty_Brightness,90);

CallSetTextVeiw(dwCard,@AShowText);

CallStartOverlay(dwCard,HlComponent,myVideo);
myVideo:=Rect(0,20,400,350);

new(NewCardRect);
//setlength(NewCardRect,4);
//setlength(NewCardRect,1);
NewCardRect.dwCard:=0;
NewCardRect.rcUser.top:=1;
NewCardRect.rcUser.left:=0;
NewCardRect.rcUser.Right:=600;
NewCardRect.rcUser.Bottom:=500;
{NewCardRect[1].dwCard:=1;
NewCardRect[1].rcUser.top:=1;
NewCardRect[1].rcUser.left:=0;

NewCardRect[3].rcUser.Bottom:=500;}
CallMapLogicScreenToUserScreen(@myVideo,@myVideo,NewCardRect,4);
Dispose(NewCardRect);
end;
上面已列出了我所做的尝试，
问题在于，我无法压入正确的参数，特别是参数NewCardRect在压入前怎么定义及
怎么样给其附值,这样还是不行。/帮我多看看。
 
看错了，不过这样应该没有什么问题了
 
你忘了在函数后面加上[red]stdcall[/red]!!!!!!
看我翻译的，以后看帖子要注意，仔细点...
 
参照下面改一下你的程序

函数声明：
function MapLogicScreenToUserScreen(rcLogic, rcUser: PRect;
pCardPos: PCAP_WND_POS, dwCardCount: DWORD);Boolean;stdcall;

调用：
type
tagCardRect = record
dwCard:DWORD;
rcUser:TRECT;
end;
CAP_WND_POS = tagCardRect;
PCAP_WND_P0S = ^CAP_WND_POS;

TMapScreen = function MapLogicScreenToUserScreen(rcLogic, rcUser: PRect;
pCardPos: PCAP_WND_POS, dwCardCount: DWORD);Boolean;stdcall;

var
LoadFunType: TMapScreen;
ARect, BRect: TRect;
ACardPos: CAP_WND_POS;
dwCardNum: DWORD;
begin
LoadFunType := TMapScreen(GetProcAddress(DllHandle, 'MapLogicScreenToUserScreen'));
if @LoadFunType<>nil then
begin
//ARect := ...
//ACardPos := ...
Result := LoadFunType(@ARect, @BRect, @ACardPos, dwCardNum);
end;
end;

你看看，如果还不行的话把你认为可以发给我的代码发过来（只要关键部分，不要业务逻辑），
我帮你改。（我的E-Mail在我的个人资料上有）
 
TMapScreen = function MapLogicScreenToUserScreen(rcLogic, rcUser: PRect;
pCardPos: PCAP_WND_POS, dwCardCount: DWORD);Boolean;stdcall;//返回值错了，
应该是BOOL，BOOL<!=boolean

//audio stream output
typedef void (CALLBACK *AuPrcCallBack)(DWORD dwCard, BYTE*pbuf, DWORD siz);
void WINAPI OutAuBuff(DWORD dwCard, AuPrcCallBack pAuCall);

//Get-Set video Capture size
void WINAPI GetVidCapSize(DWORD dwCard,DWORD &amp;dwCapWidth,DWORD &amp;dwCapHeight);
BOOL WINAPI SetVidCapSize(DWORD dwCard,DWORD dwCapWidth,DWORD dwCapHeight);

BOOL WINAPI CreateAudioAviFile(DWORD dwCard);

#endif
 
To 张无忌：在Delphi中BOOL和Boolean的确不完全一样，但不表示不可以这样用，按照我的
定义，像下面这样用是没有问题的（由于用惯了C++，我总会不由自主地按照C/C++的思路写
程序）：
if LoadFunType(@ARect, @BRect, @ACardPos, dwCardNum) then
ShowMessage('调用成功！')
else
ShowMessage('调用失败！');

而如果像这样用的话，就得不到希望的结果了：
if LoadFunType(@ARect, @BRect, @ACardPos, dwCardNum) = True then
ShowMessage('调用成功！')
else
ShowMessage('调用失败！');

以上仅是对技术的探讨，我完全赞同将返回值封装为BOOL。

To fartripLiao：你发给我的那个.pas文件不包含任何对MapLogicScreenToUserScreen的封
装和调用，我怎么知道你错在哪里呀？
 
to fartripLiao:
你的函数声明后面都没有加stdcall!!!真是晕，我告诉你了，你为什么不修改了？？？
加上应该是没问题！
 
to Sachow:
其实你上面的两种写法都可以运行，结果是一样的。。。
DELPHI在后台自动转换了。。。但是对于纯用API写的程序
还是严格一些好，否则很有可能出莫名其妙的问题，我以前
就碰到过这样的问题，找了好久才找到答案。。。
 
to 张无忌
其实我定义了其它许多的函数， 这个是后来加上去的真的忘了加其它的都有，
真糊涂我现在试试行了的都加分，
若真的这样其实我自己就可以搞定的。
