• How do I use IIS6 style metabase paths in IIS7 AppCmd tool?

  - by Mike Atlas

  I'm currently in the process of upgrading old II6 automation scripts that use the IISVdir tool to create/modify/update apps and virtual directories, and replacing them with AppCmd for IIS7. The IIS6, "IISVDir" commands reference paths in that are from the metabase, eg, "/W3SVC/1/ROOT/MyApp" - where 1 is ID of the "Default Web Site" site. The command doesn't actually require the display name of the site to make changes to it. This works well, since on a different language OS, the "Default Web Site" site name could be named, for example, "??? Web ???" or anything else for that matter. But this flexibility is lost if AppCmd can only reference "Default Web Site" via its name, and not a language-neutral identifier. So, how can I script AppCmd to refer to sites, vdirs and apps using language neutral identifiers to reference the "Default App Site"? Perhaps I need to start creating my own site instead, from the start, and name it something else specific, and stop using "Default Web Site" as the root? (Disclosure: I only have a IIS7-English machine that I am working on currently, but I have both IIS6-English and IIS6-Japanese machines for testing my old scripts - so perhaps it really is just "Default Web Site" still on Win2k8-Japanese?)

• Testing a Gui-heavy WPF application.

  - by Hamish Grubijan

  We (my colleagues) have a messy 12 y.o. mature app that is GUI-based, and the current plan is to add new dialogs & other GUI in WPF, as well as replace some of the older dialogs in WPF as well. At the same time we wish to be able to test that Monster - GUI automation in a maintainable way. Some challenges: The application is massive. It constantly gains new features. It is being changed around (bug fixes, patches). It has a back end, and a layer in-between. The state of it can get out of whack if you beat it to death. What we want is: Some tool that can automate testing of WPF. auto-discovery of what the inputs and the outputs of the dialog are. An old test should still work if you add a label that does nothing. It should fail, however, if you remove a necessary text field. It would be very nice if the test suite was easy to maintain, if it ran and did not break most of the time. Every new dialog should be created with testability in mind. At this point I do not know exactly what I want, so I am marking this as a community wiki. If having to test a huge GUI-based app rings the bell (even if not in WPF), then please share your good, bad and ugly experiences here.

• Saving "heavy" image to PDF in MATLAB - rendering problem

  - by yuk

  I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.

• How to get an enum value from an assembly using late binding in C#

  - by tetranz

  Hello I have a C# 3.0 WinForms application which is occasionally required to control Excel with automation. This is working nicely with normal early binding but I've had some problems when people don't have Excel installed but still want to use my app except for the Excel part. Late binding seems to be a solution to this. Late binding is rather tedious in C# 3 but I'm not doing anything particularly difficult. I'm following http://support.microsoft.com/kb/302902 as a starter and it's working out well. My question is how can I use an enum by name? e.g, how can I use reflection to get the value of Microsoft.Office.Interop.Excel.XlFileFormat.xlTextWindows so that I can use it an InvokeMethod call? I know the easiest way is probably to create my own local enum with the same "magic" integer value but it would be nicer to be able to access it by name. The docs often don't list the value so to get it I probably need to have a little early bound test app that can tell me the value. Thanks

• Python, Ruby, and C#: Use cases?

  - by thaorius

  Hi everyone. For as long as I can remember, I've always had a "favorite" language, which I use for most projects, until, for some particular reason, there is no way/point on using it for project XYZ. At that point, I find myself rusty (and sometimes outdated) on other languages+libraries+toolchains. So I decided, I would just use some languages/libs/tools for some things, and some for other, effectively keeping them fresh (there would obviously be exceptions, I'm not looking for an arbitrary rule set, but some guidelines). I wanted an opinion on what would be your standard use cases (new projects) for Python, Ruby, and C# (Mono). At the moment, I have time like this:Languages: C#: Mid-Large Sized Projects (mainly server-side daemons) High Performance (I hardly ever need C's performance, but Python just doesn't cut it) Relatively Low Footprint (vs the JVM, for example) Ruby: Web Applications Python: General Use Scripts (automation, system config, etc) Small-Mid Sized Projects Prototyping Web Applications About Ruby, I have no idea what to use it for that I can't use Python for (specially considering Python is more easily found installed by default). And I like both languages (though I'm really new to Ruby), which makes things even worse. As for C#, I have not used a Windows powered computer in a few years, I don't make things for Windows computers, and I don't mind waiting for Mono to implement some new features. That being said, I haven't found many people on the internet using it for server-sided *nix programming (not web related). I would appreciate some insight on this too. Thanks for your time.

• C# Late Binding for Parameterized Property

  - by optim

  I'm trying to use late binding to connect to a COM automation API provided by a program called Amibroker, using a C# WinForms project. So far I've been able to connect to everything in the API except one item, which I believe to be a "parameterized property" based on extensive Googling. Here's what the API specification looks like according to the docs (Full version here: http://www.amibroker.com/guide/objects.html): Property Filter(ByVal nType As Integer, ByVal pszCategory As String) As Long [r/w] A javascript snippet to update the value looks like this: AB = new ActiveXObject("Broker.Application"); AA = AB.Analysis; AA.Filter( 0, "market" ) = 0; Using the following C# late-binding code, I can get the value of the property, but I can't for the life of me figure out how to set the value: object[] parameter = new object[2]; parameter[0] = Number; parameter[1] = Type; object filters = _analysis.GetType().InvokeMember("Filter", BindingFlags.GetProperty, null, _analysis, parameter); So far I have tried: using BindingFlags.SetProperty, BindingFlags.SetField casting the returned object to a PropertyInfo object and trying to update the value using it adding extra object containing the value to the parameters object various other things as last-ditch efforts From what I can see, this should be straight-forward, but I'm finding the late binding in C# to be cumbersome at best. The property looks like a method call to me, which is what is throwing me off. How does one assign a value to a method, and what would the prototype for late-binding C# code look like for it? Hopefully that explains it well enough, but feel free to ask if I've left anything unclear. Thanks in advance for any help! Daniel

• Technology and language for a stable Digital Audio Workstation development

  - by Kill KRT

  Hi, I'm designing a cross platform (Windows/Linux/OS X) application, something like a digital audio workstation. I'd like to create a software where users have a fully featured sequencer (multiple tracks with automation) and where it is possible to create instruments using a visual language (as Pure Data/Max MSP). Ehm... I know that I've already posted a question about a related issue... But in order to decide which technology I should use, I think I'd better to make more investigation. I'm a quite experted user of audio trackers (Renoise, Protracker,...) and sequencers (FL Studio, Cubase 5), but I didn't ever try to develop even a basic audio tracker. I know just the basic theory of mixing sound and know how basically a DSP works. My questions are: Where I can find a good tutorial/guide/book about this issue? Do you think using C# (with NAudio) could dramatically reduce performance? I know C++ would be the best choice, but I find C# so elegant and easy to build and port, while C++ is so powerful and fast, but there are too #define and bad things for my taste! ;-) Thank you.

• How to: Simulating keystroke inputs in shell to an app running in an embedded target

  - by fzkl

  I am writing an automation script that runs on an embedded linux target. A part of the script involves running an app on the target and obtaining some data from the stdout. Stdout here is the ssh terminal connection I have to the target. However, this data is available on the stdout only if certain keys are pressed and the key press has to be done on the keyboard connected to the embedded target and not on the host system from which I have ssh'd into the target. Is there any way to simulate this? Edit: Elaborating on what I need - I have an OpenGL app that I run on the embedded linux (works like regular linux) target. This displays some graphics on the embedded system's display device. Pressing f on the keyboard connected to the target outputs the fps data onto the ssh terminal from which I control the target. Since I am automating the process of running this OpenGL app and obtaining the fps scores, I can't expect a keyboard to be connected to the target let alone expect a user to input a keystroke on the embedded target keyboard. How do I go about this? Thanks.

• deep linking in Excel sheets exported to html

  - by pomarc

  hello everybody, I am working on a project where I must export to html a lot of Excel files. This is pretty straightforward using automation and saving as html. The problem is that many of these sheets have links to worksheets of some other files. I must find a way to write a link to a single inner worksheet. When you export a multisheet excel file to html, excel creates a main htm file, a folder named filename_file, and inside this folder it writes down several files: a css, an xml list of files, a file that creates the tab bar and several html files named sheetxxx.htm, each one representing a worksheet. When you open the main file, you can click the menu bar at the bottom which lets you select the appropriate sheet. This is in fact a link, which replaces a frame content with the sheetxxx.htm file. When this file is loaded a javascript function that selects the right tab gets called. The exported files will be published on a web site. I will have to post process each file and replace every link to the other xls files to the matching htm file, finding a way to open the right worksheet. I think that I could add a parameter to the processed htm file link url, such as myfile.htm?sh=sheet002.htm if I want to link to the second worksheet of myfile.htm (ex myfile.xls). After I've exported them, I could inject a simple javascript into each of the main files which, when they are loaded, could retrieve the sh parameter with jQuery (this is easy) and use this to somehow replace the frSheet frame contents (where the sheets get loaded), opening the right inner sheet and not the default sheet (this is what I call deep linking) mimicking what happens when a user clicks on a tab. This last step is missing... :) I am considering different options, such as replacing the source of the $("frSheet") frame after document.ready. I'd like to hear from you any advice on what could be the best way to realize that in your opinion. any help is greately appreciated, many thanks.

• What's the recommended implementation for hashing OLE Variants?

  - by Barry Kelly

  OLE Variants, as used by older versions of Visual Basic and pervasively in COM Automation, can store lots of different types: basic types like integers and floats, more complicated types like strings and arrays, and all the way up to IDispatch implementations and pointers in the form of ByRef variants. Variants are also weakly typed: they convert the value to another type without warning depending on which operator you apply and what the current types are of the values passed to the operator. For example, comparing two variants, one containing the integer 1 and another containing the string "1", for equality will return True. So assuming that I'm working with variants at the underlying data level (e.g. VARIANT in C++ or TVarData in Delphi - i.e. the big union of different possible values), how should I hash variants consistently so that they obey the right rules? Rules: Variants that hash unequally should compare as unequal, both in sorting and direct equality Variants that compare as equal for both sorting and direct equality should hash as equal It's OK if I have to use different sorting and direct comparison rules in order to make the hashing fit. The way I'm currently working is I'm normalizing the variants to strings (if they fit), and treating them as strings, otherwise I'm working with the variant data as if it was an opaque blob, and hashing and comparing its raw bytes. That has some limitations, of course: numbers 1..10 sort as [1, 10, 2, ... 9] etc. This is mildly annoying, but it is consistent and it is very little work. However, I do wonder if there is an accepted practice for this problem.

• Is Accessing USB from web application for cross browser cross os possible at all ?

  - by Ved

  Hey Guys, I am wondering if there is anyway we can achieve this. I heard different things about Silverlight 4 , Java Script or Active X control but not seen any demo of code for any of them. Does anyone know any web component that is available or how to write one. We really like capture client's USB drive via Web and read/write data on it. This has to work for ANY Operating system in Any web browser. Thanks UPDATED What about WPF in browser mode...I read that I can host my wpf apps inside browser and sort of like smart client. Here is a great example of doing this via silverlight 4 but author mentions about possibility of accessing USB on MAC via 1) Enable executing AppleScripts. This option will let us have the same amount of control on a mac machine as we do on a windows machine. 2) Add an overload to ComAutomationFactory.CreateObject() that calls the “Tell Application” command under the scenes and gets a AppleScript object. This option would work extremely well for Office automation. For any other operating system feature, you’ll have to code OS access twice.  I did not quite understand it. Has any tried this ?

• Update database every 30 minutes once

  - by Ravi

  Hi, I am working on C#.Net Windows application with SQL Server 2005. This project i am using ADO.Net Data-service for database maintenance. I am working on industrial automation domain, here data keep on reading more than 8 hours. After reading data from device based on the trigger i have periodically update data to database. for example start reading data on 9.00AM, trigger firing on 9.50AM. Once trigger fire, last 30 minutes(9.20 AM to 9.50AM) data store into data base. After trigger firing keep on reading data from device and store into data base. 10.00AM trigger going to off at time storing data to database has to be stop. Again trigger firing on 11.00AM. Once trigger fire, last 30 minutes(10.30 AM to 11.00AM) data store into data base. After trigger firing keep on reading data from device and store into data base. After 10.00AM trigger not firing means data keep on store locally. Here i don't know until trigger fire keep on reading data where & how to maintain temporarily , After trigger firing, last 30 minutes data how to bring and store into database. I don't know how to achieve it. It would be great if anyone could suggest any idea. Thanks

Dictionary dictionary = new Dictionary(); Dictionary subColumns = new Dictionary(); List listOfMutations = new List(); listOfMutations.Add(new Mutation() { Column_or_supercolumn = new ColumnOrSuperColumn() { Column = new Column() { Name = utf8Encoding.GetBytes("AA"), Value = utf8Encoding.GetBytes("Answer Automation"), Timestamp = timeStamp } } }); listOfMutations.Add(new Mutation() { Column_or_supercolumn = new ColumnOrSuperColumn() { Column = new Column() { Name = utf8Encoding.GetBytes("CT"), Value = utf8Encoding.GetBytes("Call Tracker"), Timestamp = timeStamp } } }); listOfMutations.Add( new Mutation() { Column_or_supercolumn = new ColumnOrSuperColumn() { Column = new Column() { Name = utf8Encoding.GetBytes("TL"), Value = utf8Encoding.GetBytes("Track That Lead"), Timestamp = timeStamp } } }); SuperColumn superColumn = new SuperColumn() { Name=utf8Encoding.GetBytes("Indatus") }; subColumns.Add("Super1", listOfMutations); dictionary.Add("Indatus", subColumns); client.batch_mutate("Keyspace1",dictionary, ConsistencyLevel.ONE); I understand that SuperColumn struct expects List but I does not have a list of Columns. Rather I have List. Thanks in Advance.

• MVVM and avoiding Monolithic God object

  - by bufferz

  I am in the completion stage of a large project that has several large components: image acquisition, image processing, data storage, factory I/O (automation project) and several others. Each of these components is reasonably independent, but for the project to run as a whole I need at least one instance of each component. Each component also has a ViewModel and View (WPF) for monitoring status and changing things. My question is the safest, most efficient, and most maintainable method of instantiating all of these objects, subscribing one class to an Event in another, and having a common ViewModel and View for all of this. Would it best if I have a class called God that has a private instance of all of these objects? I've done this in the past and regretted it. Or would it be better if God relied on Singleton instances of these objects to get the ball rolling. Alternatively, should Program.cs (or wherever Main(...) is) instantiate all of these components, and pass them to God as parameters and then let Him (snicker) and His ViewModel deal with the particulars of running this projects. Any other suggestions I would love to hear. Thank you!

• Why is CoRegisterClassObject creating two extra threads?

  - by Stijn Sanders

  I'm trying to fix a problem that only recently happens on a number of machine's on a VPN. They each run a client application I wrote that exposes a COM automation object. For some strange reason I haven't been able to discover yet, one thread in the application takes up all of the available CPU time, slowing other operation on the machine. In observing the application's strange behaviour, I've noticed it's the third thread started, and if I debug on my machine I notice the first call to CoRegisterClassObject created two extra threads. If the second of these two threads is the one that gets into an infinite loop, I'm not at all shure how to fix this. Where could I check next about what's wrong? Could it have started by one of the recent patches rolled out by Microsoft this last 'patch tuesday'? I had a go with ProcessExplorer to extract a stack trace of the thread: ntoskrnl.exe!ExReleaseResourceLite+0x1a3 ntoskrnl.exe!PsGetContextThread+0x329 WLDAP32.dll!Ordinal325+0x1231 WLDAP32.dll!Ordinal325+0x129e WLDAP32.dll!Ordinal325+0x1178 ntdll.dll!LdrInitializeThunk+0x24 ntdll.dll!LdrShutdownThread+0xe9 kernel32.dll!ExitThread+0x3e kernel32.dll!FreeLibraryAndExitThread+0x1e ole32.dll!StringFromGUID2+0x65d kernel32.dll!GetModuleFileNameA+0x1ba

• How to check a file saving is complete using Python?

  - by indrajithk

  I am trying to automate a downloading process. In this I want to know, whether a particular file's save is completed or not. The scenario is like this. Open a site address using either Chrome or Firefox (any browser) Save the page to disk using 'Crtl + S' (I work on windows) Now if the page is very big, then it takes few seconds to save. I want to parse the html once the save is complete. Since I don't have control on the browser save functionality, I don't know whether the save has completed or not. One idea I thought, is to get the md5sum of the file using a while loop, and check against the previous one calculated, and continue the while loop till the md5 sum from the previous and current one matches. This doesn't works I guess, as it seems browser first attempts to save the file in a tmp file and then copies the content to the specified file (or just renames the file). Any ideas? I use python for the automation, hence any idea which can be implemented using python is welcome. Thanks Indrajith

• Python vs all the major professional languages [closed]

  - by Matt

  I've been reading up a lot lately on comparisons between Python and a bunch of the more traditional professional languages - C, C++, Java, etc, mainly trying to find out if its as good as those would be for my own purposes. I can't get this thought out of my head that it isn't good for 'real' programming tasks beyond automation and macros. Anyway, the general idea I got from about two hundred forum threads and blog posts is that for general, non-professional-level progs, scripts, and apps, and as long as it's a single programmer (you) writing it, a given program can be written quicker and more efficiently with Python than it could be with pretty much any other language. But once its big enough to require multiple programmers or more complex than a regular person (read: non-professional) would have any business making, it pretty much becomes instantly inferior to a million other languages. Is this idea more or less accurate? (I'm learning Python for my first language and want to be able to make any small app that I want, but I plan on learning C eventually too, because I want to get into driver writing eventually. So I've been trying to research each ones strengths and weaknesses as much as I can.) Anyway, thanks for any input

• Chicken and egg problem (restore database) when trying to write unit test against SQl Server 2008.

  - by Hamish Grubijan

  Ok, they are not unit tests but end-to-end tests. The setup is somewhat involved. Unit tests will use C#, ODBC connection. Every unit tests will try to clean up after itself, but every 20 tests or so (once per C# class) we would need to do a full database restore. I do not think I can do it over an ODBC connection, according to this document: http://www.sql-server-performance.com/articles/dba/Obtain_Exclusive_Access_to_Restore_SQL_Server_p1.aspx Msg 6104, Level 16, State 1, Line 1 Cannot use KILL to kill your own process. However, I would like to, so that 199 tests do not go amok because of a bad clean-up. Is there another way? Perhaps I can open a different "connection" such as use COM automation or something of that sort, and then kill all database connections from there? If so, how can I do that? Also, will the clients be able to re-connect automatically after a restore, or would I have to dismantle everything once every 20 tests or so? If you find this question confusing, please let me know what your questions are. Thanks!

• Mono Text Based Web Browser

  - by powerbox

  Hi guys, is there any public text based web browser implementation for C# or on mono base api that I can use to fill up web forms automatically? I'll be using it to automate some web task that does not require any image authentication. I'm currently using a web browser control available on .Net Framework and waits for the event WebBrowserDocumentCompletedEventHandler to fire after a page is successfully loaded and invoke some actions like Submit or simulating a mouse click on some links. It actually does the job but I can't process bulk transactions since I needed to wait for the whole page to be loaded together with the images and other stuff. It is easy to use HttpWebRequest to fill up some forms , provide some data and then submit. But on some occasions I only need to simulate a mouse click to a certain link which I don't know how to do with HttpWebRequest. By the way using HttpWebRequest will still download all the images of a web page that I see pointless since I only need to provide correct data back to the server. I hope someone can pinpoint me the correct way of doing this kind of automation and thanks in advance!

• Copy Word format into Outlook message

  - by Jaster

  Hi, I have an outlook automation. I would like to use a Word document as template for the message content. Lets say i have some formatted text containing tables, colors, sizes, etc. Now I'd like to copy/paste this content into an Outlook message object.I'm used to the interop stuff, i just have no idea how to copy/paste this correctly. Here is some Sample Code (no cleanup): String path = @"file.docx"; String savePath = @"file.msg"; Word.Application wordApp = new Word.Application(); Word.Document currentDoc = wordApp.Documents.Open(path); Word.Range range = currentDoc.Range(0, m_CurrentDoc.Characters.Count); String wordText = range.Text; oApp = new Outlook.Application(); Outlook.NameSpace ns = oApp.GetNamespace("MAPI"); ns.Logon("MailBox"); Outlook._MailItem oMsg = oApp.CreateItem(Outlook.OlItemType.olMailItem); oMsg.To = "[email protected]"; oMsg.Body = wordtext; oMsg.SaveAs(savePath); Using Outlook/Word 2007, however the word files still mayb in 2000/2003 format (.doc). Visual Studio 2010 with .net 4.0 (should obvious due to the samplecode). Any suggestions?

• C# and Excel best practices

  - by rlp

  I am doing a lot of MS Excel interop i C# (Visual Studio 2012) using Microsoft.Office.Interop.Excel. It requires a lot of tiresome manual code to include Excel formulas, doing formatting of text and numbers, and making graphs. I would like it very much if any of you have some input on how I do the task better. I have been looking at Visual Studio Tools for Office, but I am uncertain on its functions. I get it is required to make Excel add-ins, but does it help doing Excel automation? I have desperately been trying to find information on working with Excel in Visual Studio 2012 using C#. I did found some good but short tutorials. However I really would like a book an the subject to learn the field more in depth regarding functionality and best practices. Searching Amazon with my limited knowlegde only gives me book on VSTO using older versions of Visual Studio. I would not like to use VBA. My applications use Excel mainly for visualizing compiled from different sources. I also to data processing where Excel is not required. Futhermore, I can write C# but not VB.

• Right Language for the Job

  - by Manoj

  Using the right language for the job is the key - this is the comment I read in SO and I also belive thats the right thing to do. Because of this we ended up using different languages for different parts of the project - like perl, VBA(Excel Macros), C# etc. We have three to four languages currently in use inside the project. Using the right language for the job has made it immensly more easy to do automate a job, but of late people are complaining that any new person who has to take over the project will have to learn so many different languages to get started. Also it is difficult to find such kind of person. Please note that this is a one to two person working on the project maximum at a given point of time. I would like to know if the method we are following is right or should we converge to single language and try to use it across all the job even though another language might be better suited for it. Your experenece related to this would also help. Languages used and their purpose: Perl - Processing large text file(log files) C# with Silverlight for web based reporting. LabVIEW for automation Excel macros for processing data in excel sheets, generating graphs and exporting to powerpoint.
