指纹开发

[legion2008]

保存代码:
var
pData: PChar;
begin
with AQuery do begin
Close;
SQL.Clear;
SQL.Add('SELECT * FROM zkFingerPrint WHERE FingerID = ' + IntToStr(AFingerID));
Open;
if IsEmpty then
Append
else
Edit;
FieldByName('FingerID').Value := AFingerID;
//OQPQRTSVUQW
with TBlobStream(CreateBlobStream(FieldByName('Template'), bmWrite)) do begin
pData := VarArrayLock(AFPData);
try
Write(pData^, VarArrayHighBound(AFPData, 1) - VarArrayLowBound(AFPData, 1) + 1);
finally


读代码
with AQuery do begin
Close;
SQL.Clear;
SQL.Add('SELECT * FROM zkFingerPrint WHERE FingerID = ' + IntToStr(AFingerID));
Open;
//XQYTZ\[
if not IsEmpty then
with TBlobStream(CreateBlobStream(FieldByName('Template'), bmRead)) do begin
AFPData := VarArrayCreate([0, Size + 1], varByte);
pData := VarArrayLock(AFPData);
try
Read(pData^, Size);
finally
VarArrayUnlock(AFPData);
//写到高速缓存
FFinger.AddRegTemplateToFPCacheDB(fpcHandle, StrToInt(strDriverID),
AFPData);
问题:写到缓存后,无法识别指纹信息,请高人指点

识别指纹?别人是不会拿出来的~~这应该算高技术的东西了

[IT_superman]

高科技？？？ 真的假的啊？

已经搞定,其实也不是什么高深的东西,只要下功夫去做,没有什么解决不了的问题!

希望大家多多交流指纹开发技术，指纹平台技术与SDK开发包开发的技术差异很大！
