配方 Excel或CSV的导入导出

先来看下运行效果：

以下是实现步骤：

第一步：设计界面，参考上面的运行时设计界面即可；

第二步：创建DataFiles文件，用于存放导入导出的Excel或Csv模板来使用的

1、DataFiles文件夹里主要包含三个文件  TplPeiFang.csv（需要导入的CSV模板格式）、TplPeiFang.xlsx（需要导入的Excel模板格式）、TplPeiFangExport.xlsx（导出Excel需要被复制的模板）。注意：模板格式必须要按照这种格式

 

上图为TplPeiFang.csv 和 TplPeiFang.xlsx的格式

上图为TplPeiFangExport.xlsx 模板格式

第三步：窗口设计相关的脚本事件

1、导入按钮 左键按下 事件

Dim fileExtArray,fileName,filePath,fileExt,fileExtIsTrue,fileNameSplitArray
fileExtIsTrue=False
filePath=Sys.ProjectDir & "\DataFiles\"
fileExtArray=Array("csv","xlsx","xls")
fileName=Trim(文本框3.Text)

errorTitle="系统提示"
errorDes1="请输入文件名"
errorDes2="文件格式只支持：csv,xlsx,xls"
errorDes3="文件模板不存在"

'===================================================S_判断输入文件格式是否正确
'判断文件不能为空
If Len(fileName)<=0 then
    MsgBox errorDes1,0,errorTitle

End If
'判断文件格式只支持 csv,xlsx,xls
fileExt=LCase(Trim(fileNameSplitArray(1)))'去除左右两边空格，并将大写字母转换成小写字母
For i=0 To UBound(fileExtArray) 
    If fileExt=fileExtArray(i) then
        fileExtIsTrue=True

3、查询按钮 左键按下事件

recipNmae="Recipe.板件"
recipItemName=""
inpputValue=文本框0.Text

recipeItemList=RecipeCmd.GetRecipeItemList(recipNmae)
For i=0 To recipeItemList.Count-1
    recipeItemVlue=recipeItemList(i)
    'MsgBox recipeItemVlue
    '比对值
    valueStr=RecipeCmd.GetRecipeItemValue(recipNmae,recipNmae&"."&recipeItemVlue,recipNmae&".ID号")
    If (CStr(inpputValue) = CStr(valueStr)) then
        recipItemName=recipeItemVlue
    End If
Next

Call RecipeCmd.LoadRecipeItem(recipNmae,recipItemName)

 查询按钮 左键抬起事件

文本框0.Text=""
文本框0.Focus()
文本框0.SelectAll()

第四步：变量相关创建

第五步：窗口设计相关的属性和关联变量

1、组合框

2、ID号文本框

3、配方内容 文本框
