  • What's the best Mac custom disk image creation app?

    - by Lawrence Johnston
    I'm looking for a custom disk image creation app that I can integrate into the build process for my app (which means I need to be able to run it from the command line if possible). My desired features are that it will size the image for me, let me set the location of my icons when the image is opened, set a custom background/icon, etc. Free would be nice but if there's something that does exactly what I need I'll pay for it.

  • Usecase for Workflow Engine

    - by Icarus
    Hi, We have an issue where a Database table has to be updated on the status for a particular entity. Presently, its all Java code with a lot of if conditions and an update to the status. I was thinking along lines of using a Workflow engine since there can be multiple flows in future. Is it an overkill to use a Workflow Engine here... where do you draw the line ?

  • PHP code to convert a MySQL query to CSV

    - by Reilly
    What is the most efficient way to convert a MySQL query to CSV in PHP please? It would be best to avoid temp files as this reduces portability (dir paths and setting file-system permissions required). The CSV should also include one top line of field names. Cheers.

  • twisted reactor stops too early

    - by pygabriel
    I'm doing a batch script to connect to a tcp server and then exiting. My problem is that I can't stop the reactor, for example: cmd = raw_input("Command: ") # custom factory, the protocol just send a line reactor.connectTCP(HOST,PORT, CommandClientFactory(cmd) d = defer.Deferred() d.addCallback(lambda x: reactor.stop()) reactor.callWhenRunning(d.callback,None) reactor.run() In this code the reactor stops before that the tcp connection is done and the cmd is passed. How can I stop the reactor after that all the operation are finished?

  • Merge Mutliple Excel Workbooks

    - by IRHM
    I wonder whether someone may be able to help me please. I'm trying to use the code below to allow the user to select multiple Excel Workbooks, amalgamating the data into one 'Summary' sheet. Sub Merge() Dim DestWB As Workbook, WB As Workbook, WS As Worksheet, SourceSheet As String Set DestWB = ActiveWorkbook SourceSheet = "Input" startrow = 7 FileNames = Application.GetOpenFilename( _ filefilter:="Excel Files (*.xls*),*.xls*", _ Title:="Select the workbooks to merge.", MultiSelect:=True) If IsArray(FileNames) = False Then If FileNames = False Then Exit Sub End If End If For n = LBound(FileNames) To UBound(FileNames) Set WB = Workbooks.Open(Filename:=FileNames(n), ReadOnly:=True) For Each WS In WB.Worksheets If WS.Name = SourceSheet Then With WS If .UsedRange.Cells.Count > 1 Then dr = DestWB.Worksheets("Input").Range("C" & Rows.Count).End(xlUp).Row + 1 lastrow = .Range("C" & Rows.Count).End(xlUp).Row For j = lastrow To startrow Step -1 Select Case .Range("E" & j).Value Case "Manager", "Lead", "Technical", "Analyst" 'do nothing Case Else .Rows(j).EntireRow.Delete End Select Next lastrow = .Range("C" & Rows.Count).End(xlUp).Row If lastrow >= startrow Then .Range("B" & startrow & ":AD" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "B").PasteSpecial xlValues .Range("AF" & startrow & ":AQ" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "AF").PasteSpecial xlValues .Range("AS" & startrow & ":AS" & lastrow).Copy DestWB.Worksheets("Input").Cells(dr, "AS").PasteSpecial xlValues End If End If End With Exit For End If Next WS WB.Close savechanges:=False Next n End Sub The code works fine except for one issue which I've been trying to solve for the last few weeks. The following line of code looks in column E of the Source file, and if any of the entries match the values shown in the code it copies that row of data to paste into the Destination file. If Range("E" & j) <> "Manager" And Range("E" & j) <> "Lead" And Range("E" & j) <> "Technical" And Range("E" & j) <> "Analyst" Then Rows(j).Delete The problem I have is that if none of these values are found in the Source file, I receive the following error: Run time error '1004': Delete method of range class failed and in Debug mode it highlights this part of the line as the source of the error, but I've no idea why. Rows(j).Delete I just wondered whether someone may be able to look at this please and let me know where I'm going wrong, or perhaps even suggest a more efficient process of allowing the user to merge the workbooks. Many thanks and kind regards

  • How to set text above and below a JButton icon?

    - by mre
    I want to set text above and below a JButton's icon. At the moment, in order to achieve this, I override the layout manager and use three JLabel instances (i.e. 2 for text and 1 for the icon). But this seems like a dirty solution. Is there a more direct way of doing this? Note -I'm not looking for a multi-line solution, I'm looking for a multi-label solution. Although this article refers to it as a multi-line solution, it actually seems to refer to a multi-label solution. EXAMPLE import java.awt.Component; import java.awt.FlowLayout; import javax.swing.BoxLayout; import javax.swing.Icon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.SwingUtilities; import javax.swing.UIManager; public final class JButtonDemo { public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable(){ @Override public void run() { createAndShowGUI(); } }); } private static void createAndShowGUI(){ final JFrame frame = new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new FlowLayout()); frame.add(new JMultiLabelButton()); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } private static final class JMultiLabelButton extends JButton { private static final long serialVersionUID = 7650993517602360268L; public JMultiLabelButton() { super(); setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); add(new JCenterLabel("Top Label")); add(new JCenterLabel(UIManager.getIcon("OptionPane.informationIcon"))); add(new JCenterLabel("Bottom Label")); } } private static final class JCenterLabel extends JLabel { private static final long serialVersionUID = 5502066664726732298L; public JCenterLabel(final String s) { super(s); setAlignmentX(Component.CENTER_ALIGNMENT); } public JCenterLabel(final Icon i) { super(i); setAlignmentX(Component.CENTER_ALIGNMENT); } } }

  • How and why do I set up a C# build machine?

    - by mmr
    Hi all, I'm working with a small (4 person) development team on a C# project. I've proposed setting up a build machine which will do nightly builds and tests of the project, because I understand that this is a Good Thing. Trouble is, we don't have a whole lot of budget here, so I have to justify the expense to the powers that be. So I want to know: What kind of tools/licenses will I need? Right now, we use Visual Studio and Smart Assembly to build, and Perforce for source control. Will I need something else, or is there an equivalent of a cron job for running automated scripts? What, exactly, will this get me, other than an indication of a broken build? Should I set up test projects in this solution (sln file) that will be run by these scripts, so I can have particular functions tested? We have, at the moment, two such tests, because we haven't had the time (or frankly, the experience) to make good unit tests. What kind of hardware will I need for this? Once a build has been finished and tested, is it a common practice to put that build up on an ftp site or have some other way for internal access? The idea is that this machine makes the build, and we all go to it, but can make debug builds if we have to. How often should we make this kind of build? How is space managed? If we make nightly builds, should we keep around all the old builds, or start to ditch them after about a week or so? Is there anything else I'm not seeing here? I realize that this is a very large topic, and I'm just starting out. I couldn't find a duplicate of this question here, and if there's a book out there I should just get, please let me know. EDIT: I finally got it to work! Hudson is completely fantastic, and FxCop is showing that some features we thought were implemented were actually incomplete. We also had to change the installer type from Old-And-Busted vdproj to New Hotness WiX. Basically, for those who are paying attention, if you can run your build from the command line, then you can put it into hudson. Making the build run from the command line via MSBuild is a useful exercise in itself, because it forces your tools to be current.
