VB.NET中move方法

liguangyy 2008-11-24 03:11:58

为什么用move来重命名有时会就报错呢?用rename有时也会报错?
有没有人遇到过这种问题,对于重命名有好的解决方法吗?

你确认文件在改名(移动)前不曾使用过吗?

可以试试在资源管理器中重命名会不会出错,应该是有别的线程在使用

源文件没有关闭？源文件不存在？新文件名格式错误？新文件路径错误？

就是用move方法将一个文件重新命名报进程错误,说该文件正被另外一个进程占用.
有时候会报错,有时候却不会报错,很奇怪的.

最近在学习.net,练习绘图的一个练习代码，自己瞎折腾的，学习中，多多指教。

VB实现窗体中可以移动的图形Move实例代码，主要研究学习VB中MOVE方法的使用，图中的图形可以点击鼠标移到位置。

A Jig is a tool whereby graphics are displayed as the user is prompted to select a point, angle, etc. Think of the Copy command. When objects are selected and a base point has been selected, the Jig jumps in and displays the objects as the cursor is moved on the screen. When a Block is inserted, a Jig is used to display the block as the cursor moves around the screen. You issue the Move command. You see the objects moving as you move your cursor. It’s a jig. Jigs don’t stop there, though. A Jig is meant to aid in the user’s design work in AutoCAD.

VB窗体控件大小随窗体大小变化自動調整有时窗体变化后，如改变分辨率后控件大小却不能随之改变。手工代码调整实在麻烦，下面的模块实现自动查找窗体上控件并使其改变大小以适应窗体变化。在Form的Resize事件中调用函数Resize_All就能实现控件自动调整大小，如： Private Sub Form_Resize() Dim H, i As Integer On Error Resume Next Resize_ALL Me 'Me是窗体名，Form1,Form2等等都可以 End Sub 在模块中添加以下代码： Public Type ctrObj Name As String Index As Long Parrent As String Top As Long Left As Long Height As Long Width As Long ScaleHeight As Long ScaleWidth As Long End Type Private FormRecord() As ctrObj Private ControlRecord() As ctrObj Private bRunning As Boolean Private MaxForm As Long Private MaxControl As Long Private Const WM_NCLBUTTONDOWN = &HA1 Private Declare Function SendMessage Lib "USER32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long Private Declare Function ReleaseCapture Lib "USER32" () As Long Function ActualPos(plLeft As Long) As Long If plLeft < 0 Then ActualPos = plLeft + 75000 Else ActualPos = plLeft End If End Function Function FindForm(pfrmIn As Form) As Long Dim i As Long FindForm = -1 If MaxForm > 0 Then For i = 0 To (MaxForm -
