在implementation前声明以下函数: function RegisterServiceProcess(dwProcessID, dwType: Integer):
Integer; stdcall; external 'KERNEL32.DLL'; 在button1的OnClick 事件中:
RegisterServiceProcess( GetCurrentProcessID, 1 ); 在button2的OnClick 事件中:
RegisterServiceProcess( GetCurrentProcessID, 0 );SetWindowLong(application.Handle,GWL_ExStyle,WS_EX_ToolWindow);建立快捷方式:
const

LNK_RUN_NORMAL=1;type LINK_FILE_INFO=record

以下是程序里的一段,可以实现无限层导入:
procedure TForm8.LoadTreeView;
var
strsql,tid:string;
begin
try DataModule3.ADOTable3.open;
DataModule3.ADOTable3.Locate('DTname',RzComboBox1.Text,[lopartialkey]);
tid:=inttostr(DataModule3.ADOTable3.FieldByName('id').value);
strsql:='select * from T where TypeID='+tid;
DQ.Active :=false;
DQ.SQL.Clear ;
DQ.SQL.Add(strsql);
DQ.Active :=true;
DQ.Filtered :=true;
DQ.Filter := 'Parent=0';
U_DiGui(0,seltv.TopItem );//从当前0层开始递归建树
except
showmessage('字典里没有数据!');
end;
end;
procedure TForm8.U_DiGui(parentID:Cardinal;ParentNode:TTreeNode);
var
tmpTBData:array of TableData;
i,j:integer;
tmpNode:TTreeNode;begin
j:=DQ.RecordCount;
setlength(tmpTBData,j);//保存递规上一层结点值
for i:=0 to j-1 do begin
tmpTBData[i].ID := Cardinal(DQ.fieldbyname('ID').value);
tmpTBData[i].Name := DQ.fieldbyname('Name').value;
tmpTBData[i].ParentID := Cardinal(DQ.fieldbyname('Parent').value);
DQ.Next;
end;
for i:=0 to j-1 do begin //递规调用建立所有结点
tmpNode:=seltv.Items.AddChild(ParentNode,tmpTBData[i].Name);
// tmpNode.ImageIndex:=2;
new(pData);
pData^.ID:=tmpTBData[i].ID;
tmpNode.Data:=pData;
DQ.Filter := 'Parent=' + IntToStr(Integer(tmpTBData[i].ID));
if DQ.RecordCount >0 then begin
U_DiGui(tmpTBData[i].ID,tmpNode );
