Why clone an MS-Access recordset?

问题 I'm a newbie at VBA and attempting to understand someone else's code. Set rstClone = Me.RecordsetClone rstClone.MoveFirst Why does the recordset have to be cloned? Why can't the code be Me.Recordset.MoveFirst? 回答1: You may wish to use the recordsetclone because you do not wish to affect the records displayed in the form, which me.recordset.movefirst would do. 回答2: First off, the recordset is not cloned -- the form's Recordsetclone exists as long as there is a recordsource, even if it contains

How to make a copy of ArrayList object which is type of List?

问题 I studied Java is pass object reference by value, and in order to make a local copy of an object, I can either do clone() or copy-constructor. I also looked at deep/shallow copy as well as several post on stackoverflow. Now I am looking at example: List<String> list = new ArrayList<String>(); String one = "one" list.add(one); Few articles I read only mentions that ArrayList implements cloneable but does not really say how to make a local copy of "list" if type is List not ArrayList which does

I'm having trouble cloning a repo on git. I've been trying for to days and have tried quite a few solutions (in most the problem was slightly different but seemed to apply) but nothing has done anything to make a difference. I've tried switching off the anti-virus and firewall but that didn't help. I've also tried uninstalling and reinstalling the network adapter drivers (and restarting the computer) and that didn't work. From what I understand it's a network issue somewhere as the remote server keeps hanging up but I'm not managing to get anywhere with the issue. Using git clone -v --progress

Clone JavaFX Node?

你离开我真会死。 提交于 2019-11-28 07:10:34
问题 I have created a Node ( AnchorPane ) in the JavaFX scene builder and was wondering how to clone it. I saw Duplicate/Clone Node in JavaFX 2.0 but I need to clone the Node without re-loading the fxml. Is there any way to achieve this in JavaFX 2? 回答1: You can place the component that needs to be duplicated in a separate .fxml file. Then you can load the separate file as many times as needed adding the nodes to the appropriate root in the main scene. Additionally you can edit an <fx:include

This is my code : var a=[1,2,3] b=$.clone(a) alert(b) Doesn't jQuery have a 'clone' method?

“fatal: Not a git repository (or any of the parent directories)” from git status

别等时光非礼了梦想. 提交于 2019-11-28 04:48:24
This command works to get the files and compile them: git clone a-valid-git-url for example: git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts However, git status (or any other git command) then gives the above fatal: Not a git repository (or any of the parent directories) error. What am I doing wrong? You have to actually cd into the directory first: $ git clone git://cfdem.git.sourceforge.net/gitroot/cfdem/liggghts Cloning into 'liggghts'... remote: Counting objects: 3005, done. remote: Compressing objects: 100% (2141/2141), done. remote: Total 3005 (delta 1052), reused 2714

Copy DataGridView's rows into another DataGridView

时光毁灭记忆、已成空白 提交于 2019-11-28 03:38:56
问题 So basically I've got 2 DataGridView and I need to copy the rows from one to the other. So far I've tried: DataGridViewRowCollection tmpRowCollection = DataGridView1.Rows; DataGridViewRow[] tmpRowArray = new DataGridViewRow[tmpRowCollection.Count]; tmpRowCollection.CopyTo(tmpRowArray, 0); DataGridView2.Rows.AddRange((DataGridViewRow[]) tmpRowArray)); But it keeps saying that "Row provided already belongs to a DataGridView control." So what's the best way to copy the content of the rows (both
