关于字符串类型转换
本帖最后由 todaywlq 于 2012-03-20 13:47:32 编辑 void CZXingBarcodeReaderAppView::ShowResultL(TDesC16& message)

CAknMessageQueryDialog* dlg = new (ELeave) CAknMessageQueryDialog();

_LIT8(TEST1,"扫描结果");//
TBufC8<22> str8(TEST1);

//webservice

if (iService)
{
_ns1__GetCzxxResponse resp;
_ns1__GetCzxx gc;
gc.clientname = "symbian";
gc.qrCode = message;//此处需要传入message，但gc.qrCode 是 char* 这里要如何转换

if (iService->__ns2__GetCzxx(&gc, &resp) == SOAP_OK)
{
msg = resp.GetCzxxResult;
}
else
{
msg = "网络连接错误";
}
}

}


dlg->SetMessageTextL(msg); //此处需要显示msg，又要如何转换
dlg->RunLD();

CleanupStack::PopAndDestroy();

StartTimer();
}

Hi,

在网上搜索"描述符转换"能找到很多例子，例如：
