• Exchange Server Address Resolving to Random String

  - by William

  I am running Exchange 2013 on Windows Server 2012 R2. When I add my exchange account to Outlook, it seems to work perfectly (sending/receiving email, syncing everything), but when I open the account settings it has the following set as the Server: [email protected] I would have expects this to be: mail.domain.com since this is the DNS A record pointing to the IP of my server. Where is it getting this server name?

• I cant use wasd and arrow keys at the same time?

  - by William

  I am having this promblem where if I press one key on either one of the arrow keys or wasd, I cant press that direction on the other one unless that key is the only key of wasd or the arrow keys being pressed at that time. For example: I can press D and RIGHT, but if I do, I cant press W,A,S,LEFT,UP and DOWN. If I press A and S then I cant press LEFT and Down. Does anyone have a solution to that problem, cause I have searhed around, and found no similar problem.

• Making an outside machine visible to private network

  - by William

  Hi, I'm trying to make a server visible to a every computer on a separate network without doing anything to the server but I'm not sure what would be the best way to do this. I really just need to access one folder but my attempting at NFS mounting failed since I can't NFS mount a mounted folder. Any advice? Thanks.

• iPhone game center can't create sandbox account

  - by William Jockusch

  Whenever I try to create an account on the simulator or device, I get a message "game center account services are currently unavailable. Please try again later." Furthermore, I have never been able to sign in to the game center app on the simulator. Interestingly, if I reset my device with iTunes, I can then log in to the Game Center app with my regular apple id. But whenever if I log out, then try to create a sandbox account for an app I am developing, it always fails as described above. Any suggestions?

• DHCP server can't see other machines

  - by William

  Hi, I setup a private network from virtual machines and one of the machines is the DHCP server for the group. I want to specify a next-server for the DHCP server but I'm having trouble connecting to any of the machines that I lease IPs to. I'm just trying to do a simple ping/ssh to 10.0.0.252 (a machine with a lease) but it doesn't seem to respond. Any advice? I'm assuming I need to be able to connect to my next-server but maybe I'm wrong. Thanks.

• Open Source Excel training documentations?

  - by William

  I'm a trainer, basically. I'd like to find some sort of Excel-based training that's under the creative commons, or another awesome license. I want to use it to train others, and make it better. If this doesn't exist, I may have to write it. Because it should.

• Access Domain over Wireless

  - by William

  I have an active directory server and all hard wired clients connect perfectly fine. However any wireless clients do not recognize that they are connected to the domain, despite the dns server being appropriately set to the domain controller for both wired and wireless connections. Also - both wired and wireless clients are on the same subnet. I am using a Verizon food actiontec router. What am I missing? For instance, this is the same computer connected first via an Ethernet cable and second via the wireless.

• How to implement eCommerce susbscription service with multiple products

  - by Todd Brooks

  I've been researching eCommerce payment gateways and service offerings, but I'm an eCommerce novice, so please excuse my ignorance. I wish to set up an eCommerce solution with the following requirements: User "subscribes" to the service on a yearly basis. This service includes a single product subscription for a set amount (let's say $50/yr). User can "subscribe" to additional product services for a lesser rate per year (let's say $25/yr). I will need to store a product service unique Id of some sort for each product subscription the user subscribes to in order to show them product unique information. I also need to prevent duplicates...for example, user can subscribe to product ABC and XYZ, but not 2 of ABC. Is PayPal the best solution for something like this? Is there a better solution? Any assistance is greatly appreciated, even if just links to specific tutorials or examples. Update: It looks like Chargify could be the perfect solution.

• MSI Log Debug Log Sink

  - by Todd Kobus

  I have an InstallShield MSI project. When I pass an MSIHANDLE from an InstallScript custom action to a managed assembly initialized via DotNetCoCreateObject(), the value received within my managed code is -2. Does anyone know if it is possible to access an MSIHANDLE from an InstallScript custom action that calls into managed code via DotNetCoCreateObject()? I'd like to log my custom action results to the same log file as the rest of the installation. I am using InstallShield 2010, Windows Install 4.5 and .Net 3.5.

• How to find strong name signature without calling LoadAssembly

  - by Todd Kobus

  When reading a Windows PE file directly, I can't seem to find the strong name signature of a delay signed assembly. I can get to the CLR Header and read all those entries. Is the information in the MetaData directory specified within the CLR header? If so does anyone have an example of how to read this table? I am not interested in calling SN.exe or loading the assembly.

• Multiple rows with a single INSERT in SQLServer 2008

  - by Todd

  I am testing the speed of inserting multiple rows with a single INSERT statement. For example: INSERT INTO [MyTable] VALUES (5, 'dog'), (6, 'cat'), (3, 'fish) This is very fast until I pass 50 rows on a single statement, then the speed drops significantly. Inserting 10000 rows with batches of 50 take 0.9 seconds. Inserting 10000 rows with batches of 51 take 5.7 seconds. My question has two parts: Why is there such a hard performance drop at 50? Can I rely on this behavior and code my application to never send batches larger than 50? My tests were done in c++ and ADO.

• Can LINQ-to-SQL omit unspecified columns on insert so a database default value is used?

  - by Todd Ropog

  I have a non-nullable database column which has a default value set. When inserting a row, sometimes a value is specified for the column, sometimes one is not. This works fine in TSQL when the column is omitted. For example, given the following table: CREATE TABLE [dbo].[Table1]( [id] [int] IDENTITY(1,1) NOT NULL, [col1] [nvarchar](50) NOT NULL, [col2] [nvarchar](50) NULL, CONSTRAINT [PK_Table1] PRIMARY KEY CLUSTERED ([id] ASC) ) GO ALTER TABLE [dbo].[Table1] ADD CONSTRAINT [DF_Table1_col1] DEFAULT ('DB default') FOR [col1] The following two statements will work: INSERT INTO Table1 (col1, col2) VALUES ('test value', '') INSERT INTO Table1 (col2) VALUES ('') In the second statement, the default value is used for col1. The problem I have is when using LINQ-to-SQL (L2S) with a table like this. I want to produce the same behavior, but I can't figure out how to make L2S do that. I want to be able to run the following code and have the first row get the value I specify and the second row get the default value from the database: var context = new DataClasses1DataContext(); var row1 = new Table1 { col1 = "test value", col2 = "" }; context.Table1s.InsertOnSubmit(row1); context.SubmitChanges(); var row2 = new Table1 { col2 = "" }; context.Table1s.InsertOnSubmit(row2); context.SubmitChanges(); If the Auto Generated Value property of col1 is False, the first row is created as desired, but the second row fails with a null error on col1. If Auto Generated Value is True, both rows are created with the default value from the database. I've tried various combinations of Auto Generated Value, Auto-Sync and Nullable, but nothing I've tried gives the behavior I want. L2S does not omit the column from the insert statement when no value is specified. Instead it does something like this: INSERT INTO Table1 (col1, col2) VALUES (null, '') ...which of course causes a null error on col1. Is there some way to get L2S to omit a column from the insert statement if no value is given? Or is there some other way to get the behavior I want? I need the default value at the database level because not all row inserts are done via L2S, and in some cases the default value is a little more complex than a hard coded value (e.g. creating the default based on another field) so I'd rather avoid duplicating that logic.

• Catching an exception class within a template

  - by Todd Bauer

  I'm having a problem using the exception class Overflow() for a Stack template I'm creating. If I define the class regularly there is no problem. If I define the class as a template, I cannot make my call to catch() work properly. I have a feeling it's simply syntax, but I can't figure it out for the life of me. #include<iostream> #include<exception> using namespace std; template <class T> class Stack { private: T *stackArray; int size; int top; public: Stack(int size) { this->size = size; stackArray = new T[size]; top = 0; } ~Stack() { delete[] stackArray; } void push(T value) { if (isFull()) throw Overflow(); stackArray[top] = value; top++; } bool isFull() { if (top == size) return true; else return false; } class Overflow {}; }; int main() { try { Stack<double> Stack(5); Stack.push( 5.0); Stack.push(10.1); Stack.push(15.2); Stack.push(20.3); Stack.push(25.4); Stack.push(30.5); } catch (Stack::Overflow) { cout << "ERROR! The stack is full.\n"; } return 0; } The problem is in the catch (Stack::Overflow) statement. As I said, if the class is not a template, this works just fine. However, once I define it as a template, this ceases to work. I've tried all sorts of syntaxes, but I always get one of two sets of error messages from the compiler. If I use catch(Stack::Overflow): ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2955: 'Stack' : use of class template requires template argument list ch18pr01.cpp(13) : see declaration of 'Stack' ch18pr01.cpp(89) : error C2316: 'Stack::Overflow' : cannot be caught as the destructor and/or copy constructor are inaccessible EDIT: I meant If I use catch(Stack<double>::Overflow) or any variety thereof: ch18pr01.cpp(89) : error C2061: syntax error : identifier 'Stack' ch18pr01.cpp(89) : error C2310: catch handlers must specify one type ch18pr01.cpp(95) : error C2317: 'try' block starting on line '75' has no catch handlers I simply can not figure this out. Does anyone have any idea?

• Delphi Mock Wizard

  - by Todd

  Let me preface this by saying I'm fairly new to Unit Testing, Mocks, Stubs, Etc... I've installed Delphi-Mock-Wizard. When I select a unit and "Generate Mock", a new unit is created but it's very basic and not anything what I understand Mocks to be. unit Unit1; (** WARNING - AUTO-GENERATED MOCK! Change this unit if you want to, but be aware that any changes you make will be lost if you regenerate the mock object (for instance, if the interface changes). My advice is to create a descendent class of your auto-generated mock - in a different unit - and override things there. That way you get to keep them. Also, the auto-generate code is not yet smart enough to generate stubs for inherited interfaces. In that case, change your mock declaration to inherit from a mock implementation that implements the missing interface. This, unfortunately, is a violation of the directive above. I'm working on it. You may also need to manually change the unit name, above. Another thing I am working on. **) interface uses PascalMock, TestInterfaces; type IThingy = interface; implementation end. Looking at the source there seems to be quite a bit commented out. I'm wondering, has anyone gotten this to work? My IDE is D2010. Thanks.

• How do I specify the block object / predicate required by NSDictionary's keysOfEntriesPassingTest ?

  - by Todd

  For learning (not practical -- yet) purposes, I'd like to use the following method on an NSDictionary to give me back a set of keys that have values using a test I've defined. Unfortunately have no idea how to specify the predicate. NSDictionary keysOfEntriesPassingTest: - (NSSet *)keysOfEntriesPassingTest:(BOOL (^)(id key, id obj, BOOL *stop))predicate Let's say for example all my values are NSURLs, and I'd like to get back all the URLs that are on port 8080. Here's my stab at coding that -- though it doesn't really make sense to me that it'd be correct: NSSet * mySet = [myDict keysOfEntriesPassingTest:^(id key, id obj, BOOL *stop) { if( [[obj port] isEqual: [NSNumber numberWithInt: 8080]]) { return key; }] And that's because I get back the following compiler error: incompatible block pointer types initializing 'void (^)(struct objc_object *, struct objc_object *, BOOL *)', expected 'BOOL (^)(struct objc_object *, struct objc_object *, BOOL *)' What am I missing? I'd appreciate a pointer at some docs that go into more detail about the "Block object" that the predicate is supposed to be. Thanks!

• Importing war file into eclipse and build path problem

  - by Todd

  Hi, I am facing some weird problem when importing .war file into eclipse. The problem is, the build folder does not contain any necessary class folder. So when I try to set the build path, eclipse reports "Error while adding to build path. Reason: cannot nest output folder 'projectName/build/class' inside 'projectName/build'. From what I understand, 'build' folder is what classes get collected(as build version) right? I tried to ignore build path and just export .war file into tomcat server, but somehow servlet file keeps showing old code, which I changed in eclipse. So, I am thinking without proper build folder, exported .war will not contain modified servlect code.( I am sorry if this doesn't sound clear) What can I do to fix this problem? I already tried to create a whole new workspace and restarted eclipse several times and it didn't solve the problem.

• Implicitly including optional dependencies in Maven

  - by Jon Todd

  I have a project A which has a dependency X. Dependency X has an optional dependency Y which doens't get included in A by default. Is there a way to include Y in my POM without explicitly including it? In Ivy they have a way to essentailly say include all optional dependencies of X, does Maven have a way to do this?

• Why put a DAO layer over a persistence layer (like JDO or Hibernate)

  - by Todd Owen

  Data Access Objects (DAOs) are a common design pattern, and recommended by Sun. But the earliest examples of Java DAOs interacted directly with relational databases -- they were, in essence, doing object-relational mapping (ORM). Nowadays, I see DAOs on top of mature ORM frameworks like JDO and Hibernate, and I wonder if that is really a good idea. I am developing a web service using JDO as the persistence layer, and am considering whether or not to introduce DAOs. I foresee a problem when dealing with a particular class which contains a map of other objects: public class Book { // Book description in various languages, indexed by ISO language codes private Map<String,BookDescription> descriptions; } JDO is clever enough to map this to a foreign key constraint between the "BOOKS" and "BOOKDESCRIPTIONS" tables. It transparently loads the BookDescription objects (using lazy loading, I believe), and persists them when the Book object is persisted. If I was to introduce a "data access layer" and write a class like BookDao, and encapsulate all the JDO code within this, then wouldn't this JDO's transparent loading of the child objects be circumventing the data access layer? For consistency, shouldn't all the BookDescription objects be loaded and persisted via some BookDescriptionDao object (or BookDao.loadDescription method)? Yet refactoring in that way would make manipulating the model needlessly complicated. So my question is, what's wrong with calling JDO (or Hibernate, or whatever ORM you fancy) directly in the business layer? Its syntax is already quite concise, and it is datastore-agnostic. What is the advantage, if any, of encapsulating it in Data Access Objects?

• Ruby - Escape Parenthesis

  I can't for the life of me figure this out, even though it should be very simple. How can I replace all occurrences of "(" and ")" on a string with "\(" and "\)"?

• FluentNHibernate Many-To-One References where Foreign Key is not to Primary Key and column names are

  - by Todd Langdon

  I've been sitting here for an hour trying to figure this out... I've got 2 tables (abbreviated): CREATE TABLE TRUST ( TRUSTID NUMBER NOT NULL, ACCTNBR VARCHAR(25) NOT NULL ) CONSTRAINT TRUST_PK PRIMARY KEY (TRUSTID) CREATE TABLE ACCOUNTHISTORY ( ID NUMBER NOT NULL, ACCOUNTNUMBER VARCHAR(25) NOT NULL, TRANSAMT NUMBER(38,2) NOT NULL POSTINGDATE DATE NOT NULL ) CONSTRAINT ACCOUNTHISTORY_PK PRIMARY KEY (ID) I have 2 classes that essentially mirror these: public class Trust { public virtual int Id {get; set;} public virtual string AccountNumber { get; set; } } public class AccountHistory { public virtual int Id { get; set; } public virtual Trust Trust {get; set;} public virtual DateTime PostingDate { get; set; } public virtual decimal IncomeAmount { get; set; } } How do I do the many-to-one mapping in FluentNHibernate to get the AccountHistory to have a Trust? Specifically, since it is related on a different column than the Trust primary key of TRUSTID and the column it is referencing is also named differently (ACCTNBR vs. ACCOUNTNUMBER)???? Here's what I have so far - how do I do the References on the AccountHistoryMap to Trust??? public class TrustMap : ClassMap<Trust> { public TrustMap() { Table("TRUST"); Id(x => x.Id).Column("TRUSTID"); Map(x => x.AccountNumber).Column("ACCTNBR"); } } public class AccountHistoryMap : ClassMap<AccountHistory> { public AccountHistoryMap() { Table("TRUSTACCTGHISTORY"); Id (x=>x.Id).Column("ID"); References<Trust>(x => x.Trust).Column("ACCOUNTNUMBER").ForeignKey("ACCTNBR").Fetch.Join(); Map(x => x.PostingDate).Column("POSTINGDATE"); ); I've tried a few different variations of the above line but can't get anything to work - it pulls back AccountHistory data and a proxy for the Trust; however it says no Trust row with given identifier. This has to be something simple. Anyone? Thanks in advance.

• Scrum - Responding to traditional RFPs

  - by Todd Charron

  Hi all, I've seen many articles about how to put together Agile RFP's and negotiating agile contracts, but how about if you're responding to a more traditional RFP? Any advice on how to meet the requirements of the RFP while still presenting an agile approach? A lot of these traditional RFP's request specific technical implementations, timelines, and costs, while also requesting exact details about milestones and how the technical solutions will be implemented. While I'm sure in traditional waterfall it's normal to pretend that these things are facts, it seems wrong to commit to something like this if you're an agile organization just to get through the initial screening process. What methods have you used to respond to more traditional RFP's? Here's a sample one grabbed from google, http://www.investtoronto.ca/documents/rfp-web-development.pdf Particularly, "3. A detailed work plan outlining how they expect to achieve the four deliverables within the timeframe outlined. Plan for additional phases of development." and "8. The detailed cost structure, including per diem rates for team members, allocation of hours between team members, expenses and other out of pocket disbursements, and a total upset price."

• C array assignment and indexing with similar variable.

  - by Todd R.

  Hello! I apologize if this has been posted before. Compiling under two separate compilers, BCC 5.5 and LCC, yields 0 and 1. #include <stdio.h> int main(void) { int i = 0, array[2] = {0, 0}; array[i] = ++i; printf("%d\n", array[1]); } Am I to assume not all compilers evaluate expressions within an array from right to left?
