文件上傳下來(lái)了 又需要的 自己研究研究吧
這段時(shí)間一直在用一個(gè)國(guó)內(nèi)的VC知識(shí)庫(kù)上的一個(gè)OutLook類 今天再和這個(gè)國(guó)外的OutLook類一比較.. 汗...
以后 還是應(yīng)該多多上上國(guó)外網(wǎng)站
效果圖就不上了 自己看吧 比較華麗

煩的狠 就用火狐打開(kāi)看看 顯示 "Components Head not exist" 我的IE可沒(méi)有顯示這個(gè)信息
聯(lián)想到以前在邪八里面看到的文章 里面似乎提過(guò)User-Agent檢測(cè) 是不是這個(gè)網(wǎng)站也增加了這個(gè)檢測(cè)呢???
于是 在Post數(shù)據(jù)中在增加一行

]]>strPosInfo= m_pRecordset->GetCollect("posInfo");
更加奇怪的是 catch(...)也抓不到異常
今天碰著個(gè)問(wèn)題算是頭弄大了 最后終于弄好了
原因很簡(jiǎn)單
報(bào)錯(cuò)的問(wèn)題
錯(cuò)誤原因 在GetCollct返回了NULL之后 由于strPosInfo是一個(gè)CString對(duì)象 編譯器自動(dòng)將_varint_t轉(zhuǎn)換成CString 而此時(shí)_varint_t為空 因此轉(zhuǎn)換失敗 不是數(shù)據(jù)庫(kù)的異常 而且根本就不是異常 所以 catch(…)無(wú)法抓住
解決方案
在可能為空的地方 利用
1 _variant_t var;
2
3 var= m_pRecordset->GetCollect("posInfo"); //可能為空
4
5 if(var.vt != VT_NULL) //為NULL
6
7 strPosInfo = var;
8
9 else
10
11 strPosInfo = “”;
2
3 var= m_pRecordset->GetCollect("posInfo"); //可能為空
4
5 if(var.vt != VT_NULL) //為NULL
6
7 strPosInfo = var;
8
9 else
10
11 strPosInfo = “”;
就可以檢測(cè)NULL值了
