1.dll子視窗的式樣必須設定為無框(borderstyle:=bsnone;formstyle:=fsnormal)可以在dll.dpr中**控制
2.dll.dpr**
vardllscr: tscreen;
varptr:plongint;
begin
screen := scr;
frmdllform.top :=top;
frmdllform.left:=left;
frmdllform.width :=width;
frmdllform.height:=height;
frmdllform.borderstyle :=bsnone;
frmdllform.formstyle
:=fsnormal;
// frmdllform.show;
//定位好後在呼叫時候顯示可以防止視窗忽閃
result:=frmdllform;
end;
procedure exitdll(reason: integer);
begin
if reason = dll_process_detach then
begin
screen := dllscr;
end;
end;
exports
createdllform;
begin
dllscr := screen;
dllproc := @exitdll;
end.
3.exe.dpr主視窗呼叫**
type
;//都可以
var
frmmain: tfrmmain;
dllform: tform;
implementation
procedure tform1.panel1click(sender:tobject);
vardllhandle: thandle;
dllsub: invokedllform;
begin
dllhandle :=loadlibrary('sysnewsread.dll');
if dllhandle <> 0 then
begin
@dllsub :=getprocaddress(dllhandle, 'createdllform');
if assigned(dllsub) then
begin
if not assigned(dllform) then
begin
setwindowpos(dllform.handle, 0, 0, 0, panel1.width ,panel1.height, swp_nozorder);//可以去掉
dllform.parentwindow:=panel1.handle;//將容器設定為父視窗
windows.setparent(dllform.handle,panel1.handle);
dllform.show;//這裡顯示出視窗
end;
end;
end;
end;
e(varmsg: tagmsg;var handled:boolean);
begin
if assigned(dllform) then
ifisdialogmessage(dllform.handle,msg)thenhandled:=true
;//通過該****dll視窗的訊息。
end;
procedure tform1.panel1enter(sender:tobject);
begin
//將dll視窗設定為前景視窗
setforegroundwindow(dllform.handle);
windows.setfocus(dllform.handle);
end;
