摘　要:自從Win7開(kāi)始，不論是Win8、Win10，MSCOMCTL.OCX通用控件庫(kù)中的控件就經(jīng)常出現(xiàn)兼容性問(wèn)題。即開(kāi)發(fā)環(huán)境下的版本號(hào)和使用環(huán)境下的版本號(hào)，哪怕只有很小的差別，像6.1.9834和6.1.9818這樣，都會(huì)出現(xiàn)異常不能使用。
正　文:

    Windows系統(tǒng)自帶的通用控件庫(kù) MSCOMCTL.OCX 是一個(gè)很好的東西，尤其是TreeView樹(shù)控件，用來(lái)處理多層級(jí)的樹(shù)形結(jié)構(gòu)數(shù)據(jù)非常有用。由于在Access中沒(méi)有類似的控件，沒(méi)有其它代替解決辦法。甚至不像ListView可以用列表框或者子窗體代替，Toolbar可以用按鈕、菜單代替。

    但自從Win7開(kāi)始，不論是Win8、Win10，MSCOMCTL.OCX通用控件庫(kù)中的控件就經(jīng)常出現(xiàn)兼容性問(wèn)題。即開(kāi)發(fā)環(huán)境下的版本號(hào)和使用環(huán)境下的版本號(hào)，哪怕只有很小的差別，像6.1.9834和6.1.9818這樣，都會(huì)出現(xiàn)異常不能使用。

    我們這里仍然以TreeView控件為例，不包括本身控件庫(kù)安裝有問(wèn)題不能使用的情況，一般可能會(huì)遇到的兼容性問(wèn)題有會(huì)以下兩類：

• 不能響應(yīng)鍵盤(pán)、鼠標(biāo)事件?？梢哉＜虞d數(shù)據(jù)到樹(shù)控件，但不論是鼠標(biāo)還是鍵盤(pán)，均無(wú)法觸發(fā)相應(yīng)的事件，比如在NodeClick事件中寫(xiě)了相應(yīng)處理代碼，但點(diǎn)擊之后沒(méi)有任何反應(yīng)。
  
  
• 鍵盤(pán)、鼠標(biāo)事件一觸發(fā)就報(bào)錯(cuò)。點(diǎn)擊鼠標(biāo)、按鍵，甚至鼠標(biāo)在樹(shù)控件上移動(dòng)，事件可以響應(yīng)，但一觸發(fā)就報(bào)錯(cuò)，導(dǎo)致不能正常使用。
  
  

    這些問(wèn)題發(fā)生的頻率非常高！尤其是當(dāng)一些在實(shí)際中已經(jīng)在用的Access程序來(lái)說(shuō)，遇到實(shí)在讓人火冒三丈，因?yàn)闃I(yè)務(wù)部門(mén)等著馬上要用呢！這是在坑爹呢還是在坑爹呢！

    對(duì)于這個(gè)問(wèn)題有什么解決辦法呢？總結(jié)下來(lái)不外乎下面幾種：

1. 修改控件庫(kù)。這個(gè)控件庫(kù)是微軟的，第一優(yōu)先是希望微軟能在更新系統(tǒng)時(shí)解決掉該問(wèn)題，但從Win7到Win10，該問(wèn)題仍然頑固地存在，看來(lái)微軟是指望不上了。而我們不可能去修改控件庫(kù)，甚至通過(guò)一些破解手段修改了，但會(huì)導(dǎo)致簽名失效，還是不便于使用。
   
   
2. 不使用樹(shù)控件。但正如本文一開(kāi)頭說(shuō)的那樣，有些多層數(shù)據(jù)的展示和處理，在用過(guò)了樹(shù)控件之后，現(xiàn)在要讓人不用，實(shí)在難受。就像習(xí)慣了電氣化的現(xiàn)代人，突然沒(méi)電了，要點(diǎn)油燈、蠟燭照明，這！這！這！這日子不過(guò)了！
   
   
3. 使用其它第三方樹(shù)控件。其它第三方樹(shù)控件的問(wèn)題在于，有可能是要額外付費(fèi)的。即使找到免費(fèi)的了，由于屬性方法事件等接口不同，還需要重新編寫(xiě)程序。另外使用第三方控件需要安裝，而一些規(guī)范化的企業(yè)里面，是禁止用戶自行安裝軟件的。
   
   

    看到這里你是不是感到絕望了？是不是感覺(jué)自己被掏空了？感覺(jué)不會(huì)再愛(ài)了？

    這么想地話，你還是太年輕，圖樣圖森破！

    世上無(wú)難事，只怕有些人！要相信希望總會(huì)有的，奇跡是會(huì)出現(xiàn)的，在那個(gè)迷茫的午夜，上帝向你走來(lái)，賜給了你一道光！

    上帝說(shuō)：解決這個(gè)問(wèn)題，需要用到這一招如來(lái)神掌，我現(xiàn)在就將如來(lái)神掌的秘籍傳授給你！

------------------------------------------如來(lái)神掌秘籍分割線------------------------------------

1. Ctrl+G打開(kāi)立即窗口，輸入以下代碼并回車(chē)，將窗體另存為文本文件。

SaveAsText acForm, "Form1", CurrentProject.Path & "\Form1.txt"

重要的事情說(shuō)三遍。

2. 用記事本打開(kāi)剛才生成的文件文件 Form1.txt，找到樹(shù)控件所在的位置（如果內(nèi)容比較多，可以搜索樹(shù)控件名稱）。

3. 將從 OleData = Begin 這一行開(kāi)始，直到 End 結(jié)束的OleData部分全部選中：

4. 將上面選中的部分替換成下面這段：

                    OleData = Begin                        0x000e0000d0cf11e0a1b11ae1000000000000000000000000000000003e000300 ,

    由于網(wǎng)頁(yè)轉(zhuǎn)碼之類的問(wèn)題，請(qǐng)點(diǎn)擊這里下載該數(shù)據(jù)文件使用。

4. 回到Access立即窗口，再次輸入以下代碼并回車(chē)，將文本文件加載為窗體：

LoadFromText acForm, "Form1", CurrentProject.Path & "\Form1.txt"

    打完收工。

    重新打開(kāi)有樹(shù)控件的窗體，你會(huì)發(fā)現(xiàn)惹人厭的樹(shù)控件不能正常使用的問(wèn)題沒(méi)有了！換臺(tái)電腦，也不再出了！

鄭重聲明：

    該方法本公子親測(cè)有效，也用來(lái)救了幾次火。但由于測(cè)試樣本有限，加上本公子也還沒(méi)有完全弄懂原理，所以不保證百分之百有效！因此這里只當(dāng)作一個(gè)偏方分享出來(lái)給大家，僅供參考。
