The ultimate c# file and directory utility library?

- by Serge van den Oever

I find myself writing file and directory utility functions all the time, and I was wondering if there is good file and directory library that already implements a more extensive set than available by default in System.IO. The kind of functions I'm looking for is things like: public static void GetTemporaryDirectory() { string tempDirectory = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()); Directory.CreateDirectory(tempDirectory); return tempDirectory; } public static void CreateEmptyFile(string filename) { File.Create(filename).Dispose(); } public static void CreateEmptyFile(string path, string filename) { File.Create(Path.Combine(path, filename)).Dispose(); } public static void CreateDirectory(string path) { Directory.CreateDirectory(path); } public static void CreateDirectory(string path, string childpath) { Directory.CreateDirectory(Path.Combine(path, childpath)); }

Archiving rows dynamically

- by Serge

I was wondering what would be the best solution to dynamically archive rows. For instance when a user marks a task as completed, that task needs to be archived yet still accessible. What would be the best practices for achieving this? Should I just leave it all in the same table and leave out completed tasks from the queries? I'm afraid that over time the table will become huge (1,000,000 rows in a year or less). Or should I create another table ie task_archive and query that row whenever data is needed from it? I know similar questions have been asked before but most of them where about archiving thousands of rows simultaneously, I just need to know what would be the best method (and why) to archive 1 row at a time once it's been marked completed

Regex preg_match issue with commas

- by Serge Sf

This is my code to pre_match when an amount looks like this: $ 99.00 and it works if (preg_match_all('/[$]\s\d+(\.\d+)?/', $tout, $matches)) { $tot2 = $matches[0]; $tot2 = preg_replace("/\\\$/", '', $tot2);} I need to do the same thing for a amount that looks like this (with a comma): $ 99,00 Thank you for your help (changing dot for comma do not help, there is an "escape" thing I do not understand... Idealy I need to preg_match any number that looks like an amount with dot or commas and with or without dollar sign before or after (I know, it's a lot to ask :) since on the result form I want to scan there are phone and street numbers... UPDATE (For some reason I cannot comment on replies) : To test properly, I need to preg_replace the comma by a dot (since we are dealings with sums, I don't think calculations can be done on numbers with commas in it). So to clarify my question, I should say : I need to transform, let's say "$ 200,24" to "200.24". (could be amounts bettween 0.10 to 1000.99) : $tot2 = preg_replace("/\\\$/", '', $tot2);} (this code just deals with the $ (it works), I need adaptation to deal also with the change of (,) for (.))

SQL Server Replication

- by Serge

I have a device that continuously collects data and stores it on a local database. I would like to also replicate that data to a second computer over the network every 10 seconds to ensure data reliability. Should I use transaction replication to achieve this? What if the network connection is temporarily unavailable, will the replication service automatically transmit all the backlogged data once the connection is restored? Can the computer that collects the data be SQL Server Compact or does it have to be at least Workgroup edition to be a Publisher. The second PC will run SQL Server Express and would be a subscriber. Thanks.

Compiling C++ code with mingw under 12.04

- by golemit

I tried to setting up compiling of the C++ projects under my Ubuntu 12.04 by mingw with QT libraries. The idea was to get executable independent from variations of target Windows versions and development environments of my colleagues. It was successfully implemented under OpenSuse 12.2 with mingw32 and some additional libraries including mingw32-libqt4 and some others. Fine. However when trying to do the same under Ubuntu 12.04 with mingw-w64 including latest libraries QT-4.8.3 copied from Windows there were always errors. No luck. The typical errors in these attempts can be seen in attachments. The commands used: qmake -spec /path_to_my_conf/win32-x-g++ my_project.pro make Can someone give a hint of the problem source? I would appreciate a good advice.

SharePoint 2010 Replaceable Parameter, some observations…

- by svdoever

SharePoint Tools for Visual Studio 2010 provides a rudimentary mechanism for replaceable parameters that you can use in files that are not compiled, like ascx files and your project property settings. The basics on this can be found in the documentation at http://msdn.microsoft.com/en-us/library/ee231545.aspx. There are some quirks however. For example: My Package name is MacawMastSP2010Templates, as defined in my Package properties: I want to use the $SharePoint.Package.Name$ replaceable parameter in my feature properties. But this parameter does not work in the “Deployment Path” property, while other parameters work there, while it works in the “Image Url” property. It just does not get expanded. So I had to resort to explicitly naming the first path of the deployment path: : You also see a special property for the “Receiver Class” in the format $SharePoint.Type.<GUID>.FullName$. The documentation gives the following description:The full name of the type matching the GUID in the token. The format of the GUID is lowercase and corresponds to the Guid.ToString(“D”) format (that is, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx). Not very clear. After some searching it happened to be the guid as declared in my feature receiver code: In other properties you see a different set of replaceable parameters: We use a similar mechanism for replaceable parameter for years in our Macaw Solutions Factory for SharePoint 2007 development, where each replaceable parameter is a PowerShell function. This provides so much more power. For example in a feature declaration we can say: Code Snippet <?xml version="1.0" encoding="utf-8" ?>  <Feature Id="[[$Feature.SampleFeature.ID]]" Title="MAST [[$MastSolutionName]] Sample Feature" Description="The MAST [[$MastSolutionName]] Sample Feature, where all possible elements in a feature are showcased" Version="1.0.0.0" Scope="Site" Hidden="FALSE" ImageUrl="[[FeatureImage]]" ReceiverAssembly="[[FeatureReceiverAssemblySignature]]" ReceiverClass="[[FeatureReceiverClass]]" xmlns="http://schemas.microsoft.com/sharepoint/"> <ElementManifests> <ElementManifest Location="ExampleCustomActions.xml" /> <ElementManifest Location="ExampleSiteColumns.xml" /> <ElementManifest Location="ExampleContentTypes.xml" /> <ElementManifest Location="ExampleDocLib.xml" /> <ElementManifest Location="ExampleMasterPages.xml" />  [[GenerateXmlNodesForFiles -path 'ExampleDocLib\*.*' -node 'ElementFile' -attributes @{Location = { RelativePathToExpansionSourceFile -path $_ }}]] [[GenerateXmlNodesForFiles -path 'ExampleMasterPages\*.*' -node 'ElementFile' -attributes @{Location = { RelativePathToExpansionSourceFile -path $_ }}]] [[GenerateXmlNodesForFiles -path 'Resources\*.resx' -node 'ElementFile' -attributes @{Location = { RelativePathToExpansionSourceFile -path $_ }}]] </ElementManifests> </Feature> We have a solution level PowerShell script file named TemplateExpansionConfiguration.ps1 where we declare our variables (starting with a $) and include helper functions: Code Snippet # ============================================================================================== # NAME: product:\src\Wss3\Templates\TemplateExpansionConfiguration.ps1 # # AUTHOR: Serge van den Oever, Macaw # DATE : May 24, 2007 # # COMMENT: # Nota bene: define variable and function definitions global to be visible during template expansion. # # ============================================================================================== Set-PSDebug -strict -trace 0 #variables must have value before usage $global:ErrorActionPreference = 'Stop' # Stop on errors $global:VerbosePreference = 'Continue' # set to SilentlyContinue to get no verbose output # Load template expansion utility functions . product:\tools\Wss3\MastDeploy\TemplateExpansionUtil.ps1 # If exists add solution expansion utility functions $solutionTemplateExpansionUtilFile = $MastSolutionDir + "\TemplateExpansionUtil.ps1" if ((Test-Path -Path $solutionTemplateExpansionUtilFile)) { . $solutionTemplateExpansionUtilFile } # ============================================================================================== # Expected: $Solution.ID; Unique GUID value identifying the solution (DON'T INCLUDE BRACKETS). # function: guid:UpperCaseWithoutCurlies -guid '{...}' ensures correct syntax $global:Solution = @{ ID = GuidUpperCaseWithoutCurlies -guid '{d366ced4-0b98-4fa8-b256-c5a35bcbc98b}'; } # DON'T INCLUDE BRACKETS for feature id's!!! # function: GuidUpperCaseWithoutCurlies -guid '{...}' ensures correct syntax $global:Feature = @{ SampleFeature = @{ ID = GuidUpperCaseWithoutCurlies -guid '{35de59f4-0c8e-405e-b760-15234fe6885c}'; } } $global:SiteDefinition = @{ TemplateBlankSite = @{ ID = '12346'; } } # To inherit from this content type add the delimiter (00) and then your own guid # ID: <base>00<newguid> $global:ContentType = @{ ExampleContentType = @{ ID = '0x01008e5e167ba2db4bfeb3810c4a7ff72913'; } } # INCLUDE BRACKETS for column id's and make them LOWER CASE!!! # function: GuidLowerCaseWithCurlies -guid '{...}' ensures correct syntax $global:SiteColumn = @{ ExampleChoiceField = @{ ID = GuidLowerCaseWithCurlies -guid '{69d38ce4-2771-43b4-a861-f14247885fe9}'; }; ExampleBooleanField = @{ ID = GuidLowerCaseWithCurlies -guid '{76f794e6-f7bd-490e-a53e-07efdf967169}'; }; ExampleDateTimeField = @{ ID = GuidLowerCaseWithCurlies -guid '{6f176e6e-22d2-453a-8dad-8ab17ac12387}'; }; ExampleNumberField = @{ ID = GuidLowerCaseWithCurlies -guid '{6026947f-f102-436b-abfd-fece49495788}'; }; ExampleTextField = @{ ID = GuidLowerCaseWithCurlies -guid '{23ca1c29-5ef0-4b3d-93cd-0d1d2b6ddbde}'; }; ExampleUserField = @{ ID = GuidLowerCaseWithCurlies -guid '{ee55b9f1-7b7c-4a7e-9892-3e35729bb1a5}'; }; ExampleNoteField = @{ ID = GuidLowerCaseWithCurlies -guid '{f9aa8da3-1f30-48a6-a0af-aa0a643d9ed4}'; }; } This gives so much more possibilities, like for example the elements file expansion where a PowerShell function iterates through a folder and generates the required XML nodes. I think I will bring back this mechanism, so it can work together with the built-in replaceable parameters, there are hooks to define you custom replacements as described by Waldek in this blog post.
