我已经完成我的vb.net代码如下步骤:vb.net集图像,图片框一个接一个
从一个文本文件,并得到行包含我想要的值,在我的情况,我需要最后一个值作为“组”
创建一个图片框数组,图片框的数量是第1步中的数字。第1行有2个图片框。
之后,我想1设置从文本文件中读取到pictureboxes 1的图像(图片名称是第二value.jpg),但我还没有找到一种合适的方式来做到这一点。
对此有何建议?
我的文本文件如下:
我的代码到目前为止是:
Private PicBoxArray(9) As PictureBox
Dim value0 As String
Dim value1 As String
Dim value2 As String
Dim value3 As String
Dim fileName As String = "D:\local\MyTest1.txt"
Dim subString1 As String = "Group"
Dim lines As String() = File.ReadAllLines(fileName)
For i As Integer = 0 To lines.Length - 1
If lines(i).Contains(subString1) Then
count1 += 1
end if
Next
For i = 1 To count1
PicBoxArray(i) = New PictureBox
With PicBoxArray(i)
.Tag = i
.Size = New Size(330, 280)
If i Mod 2 = 0 Then
.Location = New Point(430, 80 + 300 * ((i - 2)/2))
Else
.Location = New Point(80, 80 + 300 * ((i - 1)/2))
End If
.Parent = Me
.Visible = True
End With
Next
Using MyReader As New Microsoft.VisualBasic.
FileIO.TextFieldParser("D:\PUB_GIS_Tagging\local\MyTest.txt")
Dim lineCount = File.ReadAllLines("D:\PUB_GIS_Tagging\local\MyTest.txt").Length
MyReader.TextFieldType = FileIO.FieldType.Delimited
MyReader.SetDelimiters(",")
Dim currentRow As String()
While Not MyReader.EndOfData
Try
currentRow = MyReader.ReadFields()
value0 = currentRow(0)
value1 = currentRow(1)
value2 = currentRow(2)
value3 = currentRow(3)
If value3 = "Group"
'======= put the picture from PicBoxArray(1) to PicBoxArray(count1) i by 1========
'====================== I am stuck here=============
End if
Catch ex As Microsoft.VisualBasic.
FileIO.MalformedLineException
MsgBox("Line " & ex.Message &
"is not valid and will be skipped.")
End Try
End While
End Using
嗨索引,非常感谢答复。我把代码放在我的应用程序中,如下所示:For i = 1 To count1 PicBoxArray(i).ImageLocation =“C:\ vb_test \”&value4&“.pdf.jpg” 接下来,每次读一行,所有图像将一起更改为新的线值。我认为在我的代码中还存在一些问题,请你看看这个吗?谢谢! – user30643 2014-10-30 05:06:33
