这个错误代码是什么意思？
此主题相关图片如下：无标题.jpg

把按钮5的单击事件下的代码贴出来看看！

 

Depart_RoleFrm_Button5_Click

 

'===============================取得机构ID===========================

Dim DID As Integer                 '机构ID

Dim cmd As new sqlcommand

Dim dt As DataTable

Dim txt As winform.textbox=e.Form.controls("textbox1")

 

cmd.c

cmd.commandtext="select * from {TDepart}"

dt=cmd.executereader()

Dim dr As DataRow=dt.find("[FullName]="& txt.value &"")

DID=dr("ID")

 

'=============================添加机构角色=================================

Dim RID As Integer                 '角色ID

Dim STR As String                 '机构角色

Dim cmd1 As new sqlcommand           '连接角色表

Dim cmd2 As new sqlcommand           '连接机构_角色表

Dim dt1 As DataTable

Dim lstR As winform.Listbox=e.Form.controls("listbox1")       '已选角色列表

Dim lstDR As winform.Listbox=e.Form.controls("listbox2")       '预览

 

cmd1.c

cmd2.c

cmd1.commandtext="select * from {Trole}"

cmd2.commandtext="inser into {TDepart_Roles} ([DepartID],[RoleID],[Remark],[CreaterID],[CreateTime]) Values('"& DID &"','"& Rid &"','"& STR &"','"& CurrentUserID &"','"& date.today() &"')"

dt1=cmd1.executereader()

 

For i As Integer =0 To lstR.items.count-1

    Dim dr1 As DataRow=dt1.find("[name]="& lstR.items(i) &"")

    RID=dr1("ID")

    STR=TXT.value & "\" & lstR.items(i)

    lstDR.items.add(STR)

Next

output.show(STR) 看看正常吗。

错误提示是这两句代码里面出的错误：

Dim dr As DataRow=dt.find("[FullName]="& txt.value &"")

Dim dr1 As DataRow=dt1.find("[name]="& lstR.items(i) &"")

 

试试

Dim dr As DataRow=dt.find("[FullName]='"& txt.value &"'")

Dim dr1 As DataRow=dt1.find("[name]='"& lstR.items(i) &"'")

是否是条件表达式的字符串连接符号&前后必须要空格隔开，楼主测试一下试试！

问题解决了

lxl说的是对的，谢谢
