我有一个名为lstSerial的列表框和一个名为txtSerials的文本框。我想要做的是搜索lstSerial以获取在txtSerials中输入的字符串。我在Microsoft Visual Basic 6.0中使用VB6,而且我很难找到文档。
感谢。

@ AlexK的答案在技术上是正确的 - 是的 - 它会起作用,但它不是首选的方式。为此目的有一个API调用:
Private Declare Function SendMessage Lib "USER32" Alias "SendMessageA" _
(ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As _
Integer, ByVal lParam As Any) As Long
'constants for searching the ListBox
Private Const LB_FINDSTRINGEXACT = &H1A2
Private Const LB_FINDSTRING = &H18F
'function to get find an item in the Listbox
Public Function GetListBoxIndex(hWnd As Long, SearchKey As String, Optional FindExactMatch As Boolean = True) As Long
If FindExactMatch Then
GetListBoxIndex = SendMessage(hWnd, LB_FINDSTRINGEXACT, -1, ByVal SearchKey)
Else
GetListBoxIndex = SendMessage(hWnd, LB_FINDSTRING, -1, ByVal SearchKey)
End If
End Function
所以你想这样做:
lstSerial.ListIndex = GetListBoxIndex(lstSerial.hWnd, txtSerials.Text)

文件; http://msdn.microsoft.com/en-us/library/aa267225(v=VS.60).aspx
dim find as string,i as long,found as boolean
find=txtSerials.text
for i=0 to lstserial.listcount - 1
if strcomp(find, lstSerial.list(i), vbTextcompare)=0 then
found = true
lstSerial.setfocus
lstSerial.listindex= i
exit for
end if
next
if not found then msgbox "not found ..."
