TAPI、lineInitialize 和 lineInitializeEx
我尝试在我的 Delphi 项目中使用 TAPI。
当我使用 lineInitializeEx 而不是 lineInitialize 时，我收到一条错误消息，例如“异常处理消息 c0000139 参数 168fc8 162820 75b4bf7c 75b4bf7c”
lineInitializeEx 的代码是：
var
initPrm: TLineInitializeExParams;
begin
FillChar(initPrm, SizeOf(initPrm), 0);
initPrm.dwTotalSize := SizeOf(initPrm);
initPrm.dwOptions := LINEINITIALIZEEXOPTION_USEEVENT; // or LINEINITIALIZEEXOPTION_USEHIDDENWINDOW
if lineInitializeEx(lineApp, HInstance, lineCallback, 'TAPI sample', nDevs, tapiVersion, initPrm) < 0 then
TLineInitializeExParams 的定义是：
TLineInitializeExParams = record
dwTotalSize,
dwNeededSize,
dwUsedSize,
dwOptions: Longint;
Handles: THandleUnion;
dwCompletionKey: Longint;
end;
当我使用 lineInitialize 时，
if lineInitialize(lineApp, HInstance, lineCallback, 'TAPI sample', nDevs) < 0 then
一切正常。
有什么想法吗？
I try to use TAPI in my Delphi project.
When I use lineInitializeEx instead of lineInitialize I get an error msg like "Exception Processing Message c0000139 Parameters 168fc8 162820 75b4bf7c 75b4bf7c"
The code with lineInitializeEx is :
var
initPrm: TLineInitializeExParams;
begin
FillChar(initPrm, SizeOf(initPrm), 0);
initPrm.dwTotalSize := SizeOf(initPrm);
initPrm.dwOptions := LINEINITIALIZEEXOPTION_USEEVENT; // or LINEINITIALIZEEXOPTION_USEHIDDENWINDOW
if lineInitializeEx(lineApp, HInstance, lineCallback, 'TAPI sample', nDevs, tapiVersion, initPrm) < 0 then
and definition of TLineInitializeExParams is:
TLineInitializeExParams = record
dwTotalSize,
dwNeededSize,
dwUsedSize,
dwOptions: Longint;
Handles: THandleUnion;
dwCompletionKey: Longint;
end;
When I use lineInitialize
if lineInitialize(lineApp, HInstance, lineCallback, 'TAPI sample', nDevs) < 0 then
everything is OK.
Is there any idea ?

TurboPower Async Professional 可能值得一看，它现已开源。这就是我们用来成功实施 TAPI 项目的方法。

Might be worth looking at TurboPower Async Professional, which is now open source. This is what we used to successfully implement a TAPI project.
