• Strange MSI error when setup.exe is run

  - by Martin Jackson

  We're using Visual Studio 2008's Setup Project to create an installer for our .NET 3.5 app. We host the .exe and .msi files on a website for our client to access, and produce new ones regularly to provide updates. This has all been fine until recently we've noticed some cases where installing via the .exe fails. The symptoms are: The .exe downloads fine, and runs fine. It appears to download the .msi successfully (the "downloading application files" step plods through happily), but then when it gets to the end of the "preparing to install" step, instead of launching the installer UI it pops up a message saying "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer package". You'd think that the .msi is just corrupt or something, but running it explicitly (even downloading it from the same location as the .exe to do so) works just fine. This problem is occurring on just some of our machines, which are running a mixture of XP and Windows7. The only pattern I can see in those machines that experience the problem is that they tend to have had the application installed on them longer (i.e. updating the app rather than installing for the first time). It seems to me that it might be something to do with how/where the .exe downloads the .msi to, and perhaps different versions are conflicting there? Has anyone experienced this before? Does anyone know where the installer .exe puts the .msi that it downloads?

• postgresql table for storing automation test results

  - by Martin

  I am building an automation test suite which is running on multiple machines, all reporting their status to a postgresql database. We will run a number of automated tests for which we will store the following information: test ID (a GUID) test name test description status (running, done, waiting to be run) progress (%) start time of test end time of test test result latest screenshot of the running test (updated every 30 seconds) The number of tests isn't huge (say a few thousands) and each machine (say, 50 of them) have a service which checks the database and figures out if it's time to start a new automated test on that machine. How should I organize my SQL table to store all the information? Is a single table with a column per attribute the way to go? If in the future I need to add attributes but want to keep compatibility with old database format (ie I may not want to delete and create a new table with more columns), how should I proceed? Should the new attributes just be in a different table? I'm also thinking of replicating the database. In case of failure, I don't mind if the latest screenshots aren't backed up on the slave database. Should I just store the screenshots in its own table to simplify the replication? Thanks!

• Python thread pool similar to the multiprocessing Pool?

  - by Martin

  Is there a Pool class for worker threads, similar to the multiprocessing module's Pool class? I like for example the easy way to parallelize a map function def long_running_func(p): c_func_no_gil(p) p = multiprocessing.Pool(4) xs = p.map(long_running_func, range(100)) however I would like to do it without the overhead of creating new processes. I know about the GIL. However, in my usecase, the function will be an IO-bound C function for which the python wrapper will release the GIL before the actual function call. Do I have to write my own threading pool?

• Should tests be self written in TDD?

  - by martin

  We run a project, which we want to solve with test driven development. I thought about some questions that came up, when initiating the project. One question was, who should write the unit-test for a feature. Should the unit-test be written by the feature-implementing programmer? Or should the unit test be written by another programmer, who defines what a method should do and the feature-implementing programmer implements the method until the tests runs? If i understand the concept of TDD in the right way. The feature-implementing programmer has to write the test by himself, because TDD is procedure with mini-iterations. So it would be too complex to have the tests written by another programmer? What would you say, should the tests in TDD written by the programmer himself or should another programmer write the tests that describes what a method can do?

• Sqlite: Selecting records spread over total records

  - by Martin

  I have a sql / sqlite question. I need to write a query that select some values from a sqlite database table. I always want the maximal returned records to be 20. If the total selected records are more than 20 I need to select 20 records that are spread over the total records. It is also important that I always select the first and last value from the table when sorted on the date. I know how to accomplish this in code but it would be perfect to have a sqlite query that can do the same. The query Im using now is really simple and looks like this: "SELECT value,date,valueid FROM tblvalue WHERE tblvalue.deleted=0 ORDER BY DATE(date)" Hope I explained what I need, thanks for your help!

• Access problems with System.Diagnostics.Process in webservice

  - by Martin

  Hello everyone. I have problems with executing a process in a webservice method on a Windows Server 2003 machine. Here is the code: Dim target As String = "C:\dnscmd.exe" Dim fileInfo As System.IO.FileInfo = New System.IO.FileInfo(target) If Not fileInfo.Exists Then Throw New System.IO.FileNotFoundException("The requested file was not found: " + fileInfo.FullName) End If Dim startinfo As New System.Diagnostics.ProcessStartInfo("C:\dnscmd.exe") startinfo.UseShellExecute = False startinfo.Arguments = "\\MYCOMPUTER /recordadd mydomain.no " & dnsname & " CNAME myhost.mydomain.no" startinfo.UserName = "user1" Dim password As New SecureString() For Each c As Char In "secretpassword".ToCharArray() password.AppendChar(c) Next startinfo.Password = password Process.Start(startinfo) I know the process is being executed because i use processmonitor.exe on the server and it tells me that c:\dnscmd.exe is called with the right parameters Full command line value from procmon is: "C:\dnscmd.exe" \MYCOMPUTER /recordadd mydomain.no mysubdomain CNAME myhost.mydomain.no The user of the created process on the server is NT AUTHORITY\SYSTEM. BUT, the dns entry will not be added! Here is the weird thing: I KNOW the user (user1) I authenticate with has administrative rights (it's the same user I use to log on the machine with), but the user of the process in procmon says NT AUTHORITY\SYSTEM (which is not the user i use to authenticate). Weirdest: If i log on to the server, copy the command line value read from the procmon logging, and paste it in a command line window, it works! Reading procmon after this shows that user1 owns the dnscmd process. Why doesn't user1 become owner of the process started with system.diagnostics.process? Is the reason why the command doesn't work?

• Customising Flex Datagrid or alternative solutions

  - by Martin

  I'm currently building an application that is presenting tabular (fetched from a webservice) data and have squirted it into a datagrid - seemed the most obvious way to present it on screen. I've now come across a few limitations in the datagrid and wonder how I might move forward. As a relative newcomer to flex development I'm a little lost. A few things I am wanting to do. The data is logically split into groups and I would like to be able to have subheadings in the grid whenever I move to a new group. I would like to be able to highligh individual cells based on their content relative to other values in the row - ie highlight the cell with the highest value in the row. Is this possible with the standard datagrid? I'm actually using the try-before-you-buy version of flex builder at the moment but I have ordered Flex Builder 3 Pro - which is on its way to me. I understand there is an 'advanced datagrid' control in this version - perhaps that will support some of what I wish to do? Alternatively - is there another way of building custom tabular data?

• Force CloudFront distribution/file update

  - by Martin

  I'm using Amazon's CloudFront to serve static files of my web apps. Is there no way to tell a cloudfront distribution that it needs to refresh it's file or point out a single file that should be refreshed? Amazon recommend that you version your files like logo_1.gif, logo_2.gif and so on as a workaround for this problem but that seems like a pretty stupid solution. Is there absolutely no other way?

• Loading a Reusable UITableViewCell from a Nib

  - by Greg Martin

  I am able to design custom UITableViewCells and load them just fine using the technique described in the thread found at http://forums.macrumors.com/showthread.php?t=545061. However, using that method no longer allows you to init the cell with a reuseIdentifier which means you have to create whole new instances of each cell at every call. Has anyone figured out a good way to still cache particular cell types for reuses, but still be able to design them in Interface Builder?

• Display arbitrary size 2d image in opengl

  - by Martin Beckett

  I need to display 2d images in opengl using textures. The image dimensions are not necessarily powers of 2. I thought of creating a larger texture and restricting the display to the part I was using but the image data will be shared with openCV so I don't want to copy data a pixel at a time into a larger texture. EDIT - it turns out that even the simplest Intel on board graphics under Windows supports none-power-of-2 textures.

• How does a virtual machine work?

  - by Martin

  I've been looking into how programming languages work, and some of them have a so-called virtual machines. I understand that this is some form of emulation of the programming language within another programming language, and that it works like how a compiled language would be executed, with a stack. Did I get that right? With the proviso that I did, what bamboozles me is that many non-compiled languages allow variables with "liberal" type systems. In Python for example, I can write this: x = "Hello world!" x = 2**1000 Strings and big integers are completely unrelated and occupy different amounts of space in memory, so how can this code even be represented in a stack-based environment? What exactly happens here? Is x pointed to a new place on the stack and the old string data left unreferenced? Do these languages not use a stack? If not, how do they represent variables internally?

• How do I get MSDeploy to skip specific folders and file types in folders as CCNet task

  - by Simon Martin

  I want MSDeploy to skip specific folders and file types within other folders when using sync. Currently I'm using CCNet to call MSDeploy with the sync verb to take websites from a build to a staging server. Because there are files on the destination that are created by the application / user uploaded files etc, I need to exclude specific folders from being deleted on the destination. Also there are manifest files created by the site that need to remain on the destination. At the moment I've used -enableRule:DoNotDeleteRule but that leaves stale files on the destination. <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:iisApp="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:iisApp="$(website)/$(websiteFolder)" -enableRule:DoNotDeleteRule</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> I have tried to use the skip operation but run into problems. Initially I dropped the DoNotDeleteRule and replaced it with (multiple) skip <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:iisApp="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:iisApp="$(website)/$(websiteFolder)" -skip:objectName=dirPath,absolutePath="assets" -skip:objectName=dirPath,absolutePath="survey" -skip:objectName=dirPath,absolutePath="completion/custom/complete*.aspx" -skip:objectName=dirPath,absolutePath="completion/custom/surveylist*.manifest" -skip:objectName=dirPath,absolutePath="content/scorecardsupport" -skip:objectName=dirPath,absolutePath="Desktop/docs" -skip:objectName=dirPath,absolutePath="_TempImageFiles"</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> But this results in the following: Error: Source (iisApp) and destination (contentPath) are not compatible for the given operation. Error count: 1. So I changed from iisApp to contentPath and instead of dirPath,absolutePath just Directory like this: <exec> <executable>$(MsDeploy)</executable> <baseDirectory>$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\</baseDirectory> <buildArgs>-verb:sync -source:contentPath="$(ProjectsDirectory)$(projectName)$(ProjectsWorkingDirectory)\Website\" -dest:contentPath="$(website)/$(websiteFolder)" -skip:Directory="assets" -skip:Directory="survey" -skip:Directory="content/scorecardsupport" -skip:Directory="Desktop/docs" -skip:Directory="_TempImageFiles"</buildArgs> <buildTimeoutSeconds>600</buildTimeoutSeconds> <successExitCodes>0,1,2</successExitCodes> </exec> and this gives me an error: Illegal characters in path: < buildresults Info: Adding MSDeploy.contentPath (MSDeploy.contentPath). Info: Adding contentPath (C:\WWWRoot\MySite -skip:Directory=assets -skip:Directory=survey -skip:Directory=content/scorecardsupport -skip:Directory=Desktop/docs -skip:Directory=_TempImageFiles). Info: Adding dirPath (C:\WWWRoot\MySite -skip:Directory=assets -skip:Directory=survey -skip:Directory=content/scorecardsupport -skip:Directory=Desktop/docs -skip:Directory=_TempImageFiles). < /buildresults < buildresults Error: Illegal characters in path. Error count: 1. < /buildresults So I need to know how to configure this task so the folders referenced do not have their contents deleted in a sync and that that *.manifest and *.aspx files in the completion/custom folders are also skipped.

• Interface Builder and Xcode integration not working

  - by Martin Cote

  After having installed the iPhone SDK 3.1.2, Interface Builder is not in sync with Xcode anymore. The light indicator at the bottom of the XIB window is grey. IB doesn't see any files from the Xcode project. Xcode is always open when I start IB. I tried rebooting. No luck. I tried removing the preferences files for Xcode/IB. No luck. I tried reinstalling Xcode/IB. Still no luck. This page explains how IB monitors the changes in Xcode. While it was an interesting read, it didn't provide any help about how to investigate my problem. Any help would be appreciated. EDIT Here's additional information. I enabled the debug logs for launchd, and I noticed the following line that appears every time Interface Builder is started: [0x0-0x1b01b].com.apple.InterfaceBuilder3[315]: Couldn't open shared capabilities memory GSCapabilities (No such file or directory) This really seems to be related to my issue.

• A queue in C using structs and dynamic memory allocation (linked list)

  - by Martin Pugh

  I am tasked with making a queue data structure in C, as a linked list. Our lecturer gave us a large amount of code to implement a stack, but we have to adapt it to create a queue. The code our lecturer gave us ends up not compiling and segfaulting at the exact same point as the code I wrote for the queue. I'm very new to structs, malloc and C in general, so there could be something painfully obvious I've overlooked. Here is the code I am using: #include <stdio.h> #include <stdlib.h> struct node{ int data; //contains the actual data struct node *prev; //pointer to previous node (Closer to front) struct node *next; //pointer to next node (Closer to back) }; typedef struct node *Nodepointer; struct queue{ Nodepointer front; Nodepointer back; }; typedef struct queue *Queuepointer; main(){ Queuepointer myqueue; //create a queue called myqueue init(myqueue); //initialise the queue Nodepointer new = (Nodepointer)malloc(sizeof(struct node)); myqueue->front = new; } int init(Queuepointer q){ q = (Queuepointer)malloc(sizeof(struct queue)); q->front = NULL; q->back = NULL; } The idea is that the queue struct 'contains' the first and last nodes in a queue, and when a node is created, myqueue is updated. However, I cannot even get to that part (pop and push are written but omitted for brevity). The code is segfaulting at the line myqueue->front = new; with the following gdb output: Program received signal SIGSEGV, Segmentation fault. 0x08048401 in main () at queue.c:27 27 myqueue->front = new; Any idea what I'm doing wrong?

• Can only "agents" build and submit Applications to Apple?

  - by Martin

  I'm afraid I know the answer to this but I'll ask on the longshot chance that I'm wrong: I've been doing some freelance work creating an iPhone application for a company. They've created their own developer account and added me as an team member with "admin" rights. That seems to be the highest assignable rights (with the only higher level being "agent" and belonging only to whoever signed up for the account). Yet, I don't have an option under the provisioning portal to create a distribution certificate or profile. Is there any way to create these myself without having to ask my client for their primary login? They're not particulary tech savy so it would be difficult to walk them through the process to create the necessary certificates (and would require me giving them a certificate request from my computer, etc. etc.). But it seems like there should be some way to create a distribution build without "agent" rights, right? Could Apple seriously expect only one person from a company to do all the building and uploading of apps to the store?

• Best approach, Dynamic OpenXML in T-SQL

  - by Martin Ongtangco

  hello, i'm storing XML values to an entry in my database. Originally, i extract the xml datatype to my business logic then fill the XML data into a DataSet. I want to improve this process by loading the XML right into the T-SQL. Instead of getting the xml as string then converting it on the BL. My issue is this: each xml entry is dynamic, meaning it can be any column created by the user. I tried using this approach, but it's giving me an error: CREATE PROCEDURE spXMLtoDataSet @id uniqueidentifier, @columns varchar(max) AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; DECLARE @name varchar(300); DECLARE @i int; DECLARE @xmlData xml; (SELECT @xmlData = data, @name = name FROM XmlTABLES WHERE (tableID = ISNULL(@id, tableID))); EXEC sp_xml_preparedocument @i OUTPUT, @xmlData DECLARE @tag varchar(1000); SET @tag = '/NewDataSet/' + @name; DECLARE @statement varchar(max) SET @statement = 'SELECT * FROM OpenXML(@i, @tag, 2) WITH (' + @columns + ')'; EXEC (@statement); EXEC sp_xml_removedocument @i END where i pass a dynamically written @columns. For example: spXMLtoDataSet 'bda32dd7-0439-4f97-bc96-50cdacbb1518', 'ID int, TypeOfAccident int, Major bit, Number_of_Persons int, Notes varchar(max)' but it kept on throwing me this exception: Msg 137, Level 15, State 2, Line 1 Must declare the scalar variable "@i". Msg 319, Level 15, State 1, Line 1 Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

• FoxPro to C#: What best method between ODBC, OLE DB or another?

  - by Martin Labelle

  We need to read data from FoxPro 8 with C#. I'm gonna do some operations, and will push some of thoses data to an SQL Server database. We are not sure what's best method to read those data. I saw OLE DB and ODBC; what's best? REQUIRMENTS: The export program will run each night, but my company runs 24h a day. The DBF could sometimes be huge. We DON'T need to modify data. Our system, wich use FoxPro, is quite unstable: I need to find a way that ABSOLUTELY do not corrupt data, and, ideally, do not lock DBF files while reading. Speed is a minor requirement: it must be quick, but requirement #4 is most important.

• How is thread synchronization implemented, at the assembly language level?

  - by Martin

  While I'm familiar with concurrent programming concepts such as mutexes and semaphores, I have never understood how they are implemented at the assembly language level. I imagine there being a set of memory "flags" saying: lock A is held by thread 1 lock B is held by thread 3 lock C is not held by any thread etc But how is access to these flags synchronized between threads? Something like this naive example would only create a race condition: mov edx, [myThreadId] wait: cmp [lock], 0 jne wait mov [lock], edx ; I wanted an exclusive lock but the above ; three instructions are not an atomic operation :(

• Java resource as file

  - by Martin Riedel

  Is there a way in Java to construct a File instance on a resource retrieved from a jar through the classloader? My application uses some files from the jar (default) or from a filesystem directory specified at runtime (user input). I'm looking for a consistent way of a) loading these files as a stream b) listing the files in the user-defined directory or the directory in the jar respectively Edit: Apparently, the ideal approach would be to stay away from java.io.File altogether. Is there a way to load a directory from the classpath and list its contents (files/entities contained in it)?

• How to log communication of a WebService running on IIS 6.0?

  - by Martin Kirsche

  I'm running an ASP.NET WebService on IIS 6.0 that shows a lot of HTTP 500 (probably just exceptions from the WebService) inside the log at %systemroot%\System32\LogFiles\W3SVC1 on a customers site. Is it possible to log the content of those HTTP responses and there requests without modifying the WebService using IIS or a plug-in for IIS? I thought of using Wireshark or Fiddler to sniff on the HTTP traffic but I would prefer to just turn on an option inside IIS to make him log the communication (this should not be to hard since it is logging the requested URLs anyway)

• Are there old versions of Windows UX guidelines somewhere?

  - by Camilo Martin

  Since I've read Windows User Experience Interaction Guidelines (there's a PDF download avaliable) I've found it to be admirably self-deprecating, humbly pointing out their own horrible UI practices long scolded by Joel Spolsky. I'd like to know, however, what they had in mind while they made those mistakes. Is this (terrific) UX Guidelines document something new, or were there previous issues of such? If so, where can I find them? My prayers to Google yielded no leniency.

• Is there a minimum spanning tree that does not contain the min/max weighted edge?

  If we have an (arbitrary) connected undirected graph G, whose edges have distinct weights, does every MST of G contains the minimum weighted edge? is there an MST of G that does not contain the maximum weighted edge? Also, I'm more thankful if someone can give a hint of the key things one must keep in mind when dealing with such MST questions. Thanks

• How do I copy object in Qt?
