• PowerPoint API, how to change slide layout programmatically

  - by 112811688864492097861

  Hello, I'm working on PowerPoint Add-In and I was faced with trouble I couldn't solve myself. The point is I need to change the slide Layout programmaticaly with C# (the Add-In Express 2009 for Office and .NET is used). If the new layout is a predefined one everything is fine but I need to set a custom layout as a new one (without slide recreating). Unfortunately, I didn't find any information on how to do it, PowerPoint object model reference documentation didn't answer me as well. There is just the ability to create a new slide that uses custom layout. I've done an experiment seria and have ensured that the Slide object stayed being the same while I have been changing layout both predefined and custom ones. I don't want to create a new slide when I need just switch the layout. Is it possible at all? Please help me to find a way of doing it. Thanks in advance.

• Volatile keyword

  - by Tiyoal

  Say I have two threads and an object. One thread assigns the object: public void assign(MyObject o) { myObject = o; } Another thread uses the object: public void use() { myObject.use(); } Does the variable myObject have to be declared as volatile? I am trying to understand when to use volatile and when not, and this is puzzling me. Is it possible that the second thread keeps a reference to an old object in its local memory cache? If not, why not? Thanks a lot.

• Calling C++/CLI Method with System::DateTime parameter requires 'ValueType' as a parameter?

  - by David Ipsen

  I'm attempting to call a method written in C++/CLI from C#. The C++/CLI code is used to update a TIMESTAMP column in an Oracle database, given a record ID and the System::DateTime object which is the .NET compatible data type for Oracle's TIMESTAMP type. The method I am calling has the following prototype: bool ChangeJobUpdateDate (int jobIdIn, System::DateTime^ updateDateIn) I've added a reference to this DLL project in a test project that I made; I'm writing the tests in C#. However, when I try to call this method from the C# unit test project, the function appears to have the following method declaration (via intellisense): bool ChangeJobUpdateDate (int jobIdIn, ValueType updateDateIn) I'm admittedly not that familiar with C++/CLI, so is there something I'm missing?

• Can you use the same Enum in multiple entities in Linq-to-SQL?

  - by Mark

  In my persistence layer, I've declared a load of Enums to represent tables containing reference data (i.e. data never changes). In Linq2SQL, I am able to set the type of an entity property to an enum type and all is well, but as soon as I set a second entity's property to use the same enum type, the Code Generator (MSLinqToSQLGenerator) start generating an empty code file. I assume that MSLinqToSQLGenerator is quietly crashing. The question is why, and are there any work-arounds? Anyone else experienced this problem?

• Referenced assembly won't load in new thread on IIS 7

  - by DanielC

  I have a process in which a user uploads a file to a web site where the file is then processed and uploaded into the database. The process of validating the file could take several minutes so as soon as the file is uploaded I create a new thread and I do my processing on this second thread. This works great on my local machine but doesn't work at all on my IIS 7 test server. After some investigating I found the problem is that the process is trying to load a reference to Castle and it can't find the DLL. I have a copy of Castle DLLs in my bin and it works elsewhere in my app. I ran Fuslog and discovered that it is trying to load castle from the wrong location. It is trying to load from c:/windows/system32/inetsrv/. It appears that under IIS 7 the second thread is executing in a different context or something. So the question is what can I do to get it to find Castle in the application BIN folder?

• resource embedding in asp.net

  - by Mike

  I have a project which needs to generate PDF documents. I am using iTextSharp. I have a pdf which needs to be read and then appended to. To read the pdf document, I'm using PdfReader(), which accepts many forms, but I can't figure out how to reference a pdf in my webapplication to PdfReader. My host does not allow Binary Serialization (apparently that's bad), so I don't think I can load from an embedded resource. I've tried just using PdfReader("report.pdf"), but it keeps throwing an exception telling me that the file isn't found. I've tried putting the file in the bin directory, root directory, in the same directory as the class, but this still doesn't work. It works if I use a fully qualified path to the pdf document, but I can't use that when I upload it to my hosting provider. Does anyone have any suggestions on how I should do this? Thanks

• C# overloading with generics: bug or feature?

  - by TN

  Let's have a following simplified example: void Foo<T>(IEnumerable<T> collection, params T[] items) { // ... } void Foo<C, T>(C collection, T item) where C : ICollection<T> { // ... } void Main() { Foo((IEnumerable<int>)new[] { 1 }, 2); } Compiler says: The type 'System.Collections.Generic.IEnumerable' cannot be used as type parameter 'C' in the generic type or method 'UserQuery.Foo(C, T)'. There is no implicit reference conversion from 'System.Collections.Generic.IEnumerable' to 'System.Collections.Generic.ICollection'. If I change Main to: void Main() { Foo<int>((IEnumerable<int>)new[] { 1 }, 2); } It will work ok. Why compiler does not choose the right overload?

• what the java command's -jar option really does

  - by JBoy

  Does the -jar option of the java command also compile the sources before running the main method? I believe so but i would like to have a better understanding of the internal process, from the man page you can clearly see a small workflow sequence: -jar Execute a program encapsulated in a JAR file. The first argument is the name of a JAR file instead of a startup class name. In order for this option to work, the manifest of the JAR file must contain a line of the form Main-Class: classname. Here, classname identifies the class having the public static void main(String[] args) method that serves as your application's starting point. See the Jar tool reference page and the Jar trail of the Java Tutorial @ But it does not mention that it compiles the sources.

• C++ - How to call a member function for an inherited object.

  - by Francisco P.

  Hello! I have a few classes (heat, gas, contact, pressure) inheriting from a main one (sensor). I have a need to store them in a vector<Sensor *> (part of the specification). At some point in time, I need to call a function that indiscriminately stores those Sensor *. (also part of the specification, not open for discussion) Something like this: for(size_t i = 0; i < Sensors.size(); ++i) Sensors[i]->storeSensor(os) //os is an ofstream kind of object, passed onwards by reference Where and how shall storeSensor be defined? Is there any simple way to do this or will I need to disregard the specification? Mind you, I'm a beginner! Thanks for your time!

• In Drupal, can you control block display according to e.g. number of URL parts?

  - by james6848

  I'm having a little trouble controlling page-specific block display in Drupal... My URL's will be of this typical structure: http://www.mysite.co.uk/section-name/sub-page/sub-sub-page The 'section-name' will effectively be fixed, but there will be many sub-pages (far too many to explicitly reference). I need to somehow control block display as follows: One block will show on all pages where URL contains 'section-name/sub-page' but not on pages 'section-name/sub-page/sub-sub-page' Conversely, another block will show on all pages where URL contains 'section-name/sub-page/sub-sub-page' but not on pages 'section-name/sub-page' My only idea is to do a bit of PHP that looks for the string 'section-name' and then also counts URL parts (or even the number of slashes). Not sure how to implement that though :) Your help would be appreciated!

• Yahoo Astra flash component error BaseScrollPane not found

  - by Chris

  I'm trying to use the Astra library from Yahoo but I'm getting an error saying the base class BaseScrollPane is not found. It appears to be imported from fl.containers.BaseScrollPane, which leads me to believe it should be a part of the base flash 10 library and therefore should be available, but it appears to be missing. Is this part of a separate package from somewhere? Update: For what it's worth, I found the actual class files in the Configuration/Component Source folder on my hard drive, but adding that to the class path (as well as the Components directory) did no good. I ended up fixing the issue by dragging a scroll pane component to the stage from the Components window and then deleting it, but I'm not sure what exactly that action changed that made it work, and would like to know for future reference.

• Nuget and Source Control Files to Exclude?

  - by Peter Kellner

  I know I should be using nuget more but at this point I don't completely understand the nuances so I still tend to either get source and build the project, then reference the project, or I create my own "dlls" folder and hand copy the dll's in. As part of my learning process, I'm trying to understand what is critical and what is not when using nuget. For example, I've done install-package restsharp and now when I check into source control, I get files like "packages/RestSharp.103.4/lib/net4/RestSharp.xml". I'm assuming that nuget will help me with upgrading and such and it needs to have certain meta data type files. My question is: Should I be ignoring any or all files in the "packages" directory? If so, what and why. Thanks

• Setting parameters after obtaining their values in stored procedures

  - by user1260028

  Right now I have an upload field while uploads files to the server. The prefix is saved so that it can later be obtained for retrieval. For this I need to attach the ID of the form to the prefix. I would like to be able to do this as such: @filePrefix = SCOPE_IDENTITY() + @filePrefix; However I am not so sure this would work because the record has not been created yet. If anything I could call an update function which obtains the ID and then injects it into the row after it has been created. To speed things up, I don't want to do this on the server but rather do this on the database. Regardless of what the approach is, I would still like to know if something like the above is possible (at least for future reference?) So if we replace that with @filePrefix = 5 + @filePrefix; would that be possible? SQL doesn't seem to like the current syntax very much...

• Bundling images with Blackberry

  - by Casebash

  How do I get bundled images with the BlackBerry Eclipse Plugin 1.1 Beta? I copied an image into "res/background.jpg" and tried to load it using Bitmap.getBitmapResource on background.jpg. Unfortunately, the image wasn't found (Illegal argument exception). I tried moving my image file into the src folder as per the advice here, but that didn't work either. I have opened up the .jar file and the background image is present at the root of the .jar file. The option to convert image files to .png isn't selected either.

• Mock Objects properties not changing

  - by frictionlesspulley

  I am new to using Mock test in .Net. I am testing out a financial transaction which is of the following nature: int amt =20; //sets all the props and func and returns a FinaceAccount. //Note I did not SetUp the amt of the account. var account =GetFinanceAccount() //service layer to be tested _financeService.tranx(account,amt); //checks if the amt was added to the account.amt //here the amt comes out same as that set in GetFinanceAccount. Assert.AreEqual(account.amt ,amt) I know that the function tranx works correctly but there is an issue with the test. Are there any GOOD reference material on Mocking in .Net

• Android App Support Options

  - by Pughjl

  I've got a free app I'm planning on submitting to the marketplace. Looking over the submission form I see they expect a web site or email for support. Users?! I've got to worry about users if I submit an app? I suppose I would like to get some abuse from users, but I don't want to go broke doing it. So what are my options? I have a web site--I suppose I could install forum software on it--that sounds like a lot of work though. Some apps reference a blogspot page--or I could use my Word Press site. They seems a bit disorganized for getting user feedback though.

• MVC + Repository Pattern - Still depends on Data Model?

  - by Jack

  I've started a project for school in which I am using ASP.NET MVC 2 + LINQ2SQL, and a business layer so my UI doesnt interact with the DB directly. My question is this: In my MVC project, when bringing up views and passing around data, I still have to include my Data project for access to the classes in my Linq2Sql project. Is this correct? Example: Controller: ClassesRepository cr = new ClassesRepository(); // this is from my Business project Class classToEdit = cr.GetByClassId(id); // "Class" is from my data project I still have to reference the Class class in my linq2sql data project - shouldn't my UI be completely independent of my data layer? Or maybe I'm going about this all wrong.

• How to use SSRS to retrieve HTML snippets with embedded images the easy way

  - by Ram

  I have a web-app that retrieves reports from our SSRS server dynamically - we hit a URL and out pops some HTML4.0 which I stuff into a div for the user to view. I recently tried adding a report that has an embedded image (in the RDL itself) and the image doesn't make it through. What does make it through is an IMG SRC reference back to the SSRS box but we do not allow end users to hit the SSRS box directly... users query the web-app and the web-app interacts with the SSRS service. There is an option to render in MHTML (note that we typically use rs:command=RenderHTML with rs:format=HTML4.0) - the blob returned appears to be valid MIME but does not seem friendly for stuffing into a DIV... am I missing something obvious? My next step is to parse the MIME, swizzle the references and stuff the whole thing back into the page but I feel like this is the hardway. What is the easy way to retrieve HTML snippet reports out of SSRS with embedded images?

• 'cross-referencing' DataTable's

  - by Lee

  I have a DataGridView that is being filled with data from a table. Inside this table is a column called 'group' that has the ID of an individual group in another table. What I would like to do, is when the DataGridView is filled, instead of showing the ID contained in 'group', I'd like it to display the name of the group. Is there some type of VB.net 'magic' that can do this, or do I need to cross-reference the data myself? Here is a breakdown of what the 2 tables look like: table1 id group (this holds the value of column id in table 2) weight last_update table2 id description (this is what I would like to be displayed in the DGV.) BTW - I am using Visual Studio Express.

• Linking error in OMNeT++ using Boost serialization library

  - by astriffe

  I'm very new to OMNeT++ and I'd like to use the serialization-library contained in the boost framework. However, when trying to use it, I get quite many errors such as: Description Resource Path Location Type undefined reference to `boost::archive::archive_exception::~archive_exception()' OmCCN line 36, external location: /home/alexander/UniBE/BT/simulator/boost-compiledLibs /include/boost/serialization/throw_exception.hpp C/C++ Problem . I guess the problem is that I didn't yet link the compiled library in OMNeT. I've had a look at the makefile but any changes there are worthless since it is generated automatically by makemake. Furthermore, trying to access the menu item 'makemake' in project properties OMNeT++ IDE throws an error (The currently displayed page contains invalid values). Can anyone give me a hint concerning what the error could cause or how to link the compiled library correctly? Any hints are very appreciated! cheers alex

• JQuery selectors select from an html object other than from document root?

  - by orangebrainer

  jQuery selectors select from the document. How do I select from somewhere else other than root? Say I want to select some children from an html object. For this function dothis(obj) { $j("#tabs").removeClass(); $j("#tabs>ul").removeClass(); $j("#tabs>ul>li>a").each(function() { var tabNum = $j(this).attr("href").replace("#", ""); var tabContent = $j("div[id=" + tabNum + "]"); tabContent.removeClass(); $(tabContent).before("<br><h1>" +$j(this).text() + "</h1>\n" ); }); $j("#tabs>ul").each(function() { $j(this).empty();//remove Ul links on top }); } I want to reference the selectors from an html Object (obj) i passed into as argument, instead of selecting from document. Sorry I'm pretty new to jQuery.
