• Insert value in SQL database

  - by littleBrain

  In SQL Server 2005, I'm trying to figure out How to fill up the following fields? Any kind of help will be highly appreciated.. INSERT INTO [Fisharoo].[dbo].[Accounts] ([FirstName] ,[LastName] ,[Email] ,[EmailVerified] ,[Zip] ,[Username] ,[Password] ,[BirthDate] ,[CreateDate] ,[LastUpdateDate] ,[TermID] ,[AgreedToTermsDate]) VALUES (<FirstName, varchar(30),> ,<LastName, varchar(30),> ,<Email, varchar(150),> ,<EmailVerified, bit,> ,<Zip, varchar(15),> ,<Username, varchar(30),> ,<Password, varchar(50),> ,<BirthDate, smalldatetime,> ,<CreateDate, smalldatetime,> ,<LastUpdateDate, smalldatetime,> ,<TermID, int,> ,<AgreedToTermsDate, smalldatetime,>)

• What is the purpose of CS0161 when switching over an enum and how to work around it?

  - by Danvil

  Consider the following example of a simple enum and a switch over all possible enum values. enum State { Alpha, Beta, Gamma } State state = ...; switch(state) { case Alpha: ... break; case Beta: ... break; case Gamma: ... break; } Now I get error CS0161: not all code paths return a value. This seems rather pointless to me, because I would expect that other cases are not possible. So what is the purpose of this error, and how would one work around this in the most elegant way?

• Operator Overloading for Queue C++

  - by Josh

  I was trying to use the overload operator method to copy the entries of one queue into another, but I am going wrong with my function. I don't know how else to access the values of the queue "original" any other way than what I have below: struct Node { int item; Node* next; }; class Queue { public: [...] //Extra code here void operator = (const Queue &original); protected: Node *front, *end; } void Queue::operator=(const Queue &original) { //THIS IS WHERE IM GOING WRONG while(original.front->next != NULL) { front->item = original.front->item; front->next = new Node; front = front->next; original.front = original.front->next; } }

• Python CSV file processing

  - by kingwarchief

  I just got introduced to python, the first language I get to learn, and I have this question below: I have an excel based CSV file with two columns (or rows, Pythonically) that I am working on. What I need to do is to perform some operations so that I can compare the two data entries in each 'row'. To be more precise, one column has constant numbers all the way down, whereas the other column varies. So I need to count the number of times the varying column data entry values crosses the constant value on the other column. For example: Varying Column; Constant Column 24 25 26 25 crosses 27 25 26 25 25.5 25 23 25 crossed 26 25 crossed So in this case the number of times there is a cross

• How to get a green to show up like the charging battery on the iPhone lock screen?

  - by tarheel

  I am trying to get a color to show up on screen just like the charging battery (shown here): After looking at the Apple Documentation on UIColor here, I have attempted using both colorWithHue:saturation:brightness:aplha: and colorWithRed:green:blue:alpha: to get a color to show up like that. For example when I use colorWithHue:.3 saturation:.84 brightness:1 alpha:.5 on a black background, it renders a color like this: or the colorWithRed:0 green:1 blue:0 alpha:.5 on a black background shows up like this: It doesn't have that translucent or glossy look to it. Is there a better method to use? Or do I just not have the values right? (I have tried many combinations)

• Why is TargetInvocationException treated as uncaught by the IDE?

  - by Jason Coyne

  I have some code that is using reflection to pull property values from an object. In some cases the properties may throw exceptions, because they have null references etc. try { child.Target = propertyInfo.GetValue(target, null); } catch (TargetInvocationException ex) { child.Target = ex.InnerException.Message; } catch (Exception ex) { child.Target = ex.Message; } Ultimately the code works correctly, however when I am running under the debugger : When the property throws an exception, the IDE drops into the debugger as if the exception was uncaught. If I just hit run, the program flows through and the exception comes out as a TargetInvocationException with the real exception in the InnerException property. How can I stop this from happening?

• Problem invoking C DLL in C#

  - by CristiC

  I'm currently trying to invoke a method made in C from C# C code looks like this: extern "C" int addSum(int a, int b) { return a*b; } extern "C" int getCount() { return 12; } and C# code looks like this: [DllImport("mydll.dll", SetLastError=true)] private static extern int addSum(IntPtr a, IntPtr b); [DllImport("mydll.dll", SetLastError = true)] private static extern int getCount(); public static int mySum(int a, int b) { return suma(a, b); } public static int getMyCount() { return getCount(); } The code returns the right values but i'm getting the following error: addSum' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature. Any sugestion regarding this issue ? Thanks

• ImageView source scaling done right. How?

  - by Aleksey Malevaniy

  Scope Image bitmap have to be shown as imageView.setImageBitmap(bitmap) and scaled to fit UI. This could be done via: bitmap = Bitmap.createScaledBitmap(bitmap, newWidth, newHeight, true); xml's ImageView attributes such as android:layout_width="newWidth" android:layout_height="newHeight" android:adjustViewBounds="true" android:scaleType="fitCenter" Problem Which way is better for performance? I prefer xml 'cause this is UI specific problem and I prefer to use xmls for UI definition. Also we set width/height values in dp, it means we have the same UI for different screens. Thanks!

• What's the difference between PATH_NOT_FOUND and NAME_NOT_FOUND

  - by Benjamin

  In Win32 layer, we often meet ERROR_PATH_NOT_FOUND, ERROR_NAME_NOT_FOUND. When does WinAPI(eg CreateFileW, RemoveDirectoryW) return these values? And What's the difference? If I write a file system driver, when do I set STATUS_OBJECT_PATH_NOT_FOUND or STATUS_OBJECT_NAME_NOT_FOUND? I'm so confused. Is there anyone who can explain clearly? Or are there any documents explain this? I couldn't find them. Thanks in advance.

• Code Interaction with Quartz Composition

  - by Alberto MQO

  Hi, i have a Quartz Composition with a Cube, and X/Y/Z rotation inputs are published. On Interface Builder i made a QCView and a QCPatchController with the previous Quartz Composition loaded. In QCView the Patch Controller is binded, and the rotation published ports are binded too to three NSSlider, so when i change the value of the NSSlider's then the cube rotates. All this works fine, but i want to change the rotation values of the cube from the App Delegate on XCode. I tried to change the value of the NSSliders with IBoulets pointing to them, but this change doesnt apply to the cube, like it does when i change the Sliders directly with my mouse. What should i instanciate and/or how to access and change this Input_Ports.value throught the CQPatchController? Thank you very much for reading, i really need help!

• Why doesn't MySQL support millisecond / microsecond precision?

  - by Byron Whitlock

  So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?

• HowTo parse numbers from string with BOOST methods?

  - by mosg

  Problem: Visual C++ 10 project (using MFC and Boost libraries). In one of my methods I'm reading simple test.txt file. Here is what inside of the file (std::string): 12 asdf789, 54,19 1000 nsfewer:22!13 Then I'm reading it and I have to convert all digits to int only with boost methods. For example, I have a list of different characters which I have to parse: ( ’ ' ) ( [ ], ( ), { }, ? ? ) ( : ) ( , ) ( ! ) ( . ) ( - ) ( ? ) ( ‘ ’, “ ”, « » ) ( ; ) ( / ) And after conversation I must have some kind of a massive of int's values, like this one: 12,789,54,19,1000,22,13 Maybe some one already did this job? PS. I'm new for boost. Thanks!

• Cached Jquery selector behavior that I do not understand

  - by gaoshan88

  Given the following code why am I getting different values for a and b? I would have thought they would return the same thing: (function() { var a = $('#foo'); var Test = function(){ console.log(a); //outputs 'jQuery()' var b = $('#foo'); console.log(b); //outputs 'jQuery(select#foo)' which is what I want }; })(); This question stems from me trying to stick frequently used selectors into vars. Originally I was doing it in each method (like I did with var b in the above example) but then I found I needed to use the selectors in multiple methods so I moved the assignment out to be available (or so I thought) to all of the methods in that anonymous function. As you can see, it does not work. Why is this?

  I have a vector that should contain n sequences from 00 to 11 A = [00;01;02;03;04;05;06;07;08;09;10;11;00;01;02;03;04;05;06;07;08;09;10;11] and I would like to check that the sequence "00 - 11 " is always respected (no missing values). for example if A =[00;01;02; 04;05;06;07;08;09;10;11;00;01;02;03;04;05;06;07;08;09;10;11] (missing 03 in the 3rd position) For each missing value I would like to have back this information in another vector missing= [value_1,position_1; value_2, position_2; etc, etc] Can you help me?

• Data clean up: are there libraries of common permutations that we can use? Or is there a better appr

  - by anyaelena

  We are working on clean-up and analysis of a lot of human-entered customer data. We need to decide programmatically whether 2 addresses (for example) are the same, even though the data was entered with slight variations. Right now we run each address through fairly simplistic string replacement (replacing avenue with ave, for example), concatenate the fields and compare the results. We are doing something similar with names. At the very least, it seems like our list of search-replace values should already exist somewhere. Or perhaps you can suggest a totally different and superior way to detect matches?

• Post High Score and Retrieve Position

  - by majman

  I'm not so savvy with MYSQL, so my apologies in advance is this is a dumb question. I've created a super basic PHP High Scores table. Upon inserting a new score into the DB Table, I'd like to retrieve the position of that score so that I can get 10 results with the persons score falling within that range. My INSERT Query looks something like: $stmt = $mysqli->prepare("INSERT INTO highscores (name, time, score) VALUES (?, ?, ?)"); $stmt->bind_param('sdi', $name, $time, $score); UPDATE - I'm looking for a way to do this with as few queries as possible. I recall reading something about getting an INSERT ID when making an insert, but I would then still have to make a second query to get those results.

• StreamInsight complex query with filter on HoppingWindow

  - by hh354

  I'm trying out StreamInsight and I came across a problem with a query I need. I'm trying to throw a warning if there are several changes in my measured values (of up to 20% change) in the last 30 minutes. This is the query I came up with for now but it isn't working and it's not even correct I think. Apparently I can't filter on a window...? var deviationQuery = from s in wcfStream group s by s.SensorId into grouped from window in grouped.HoppingWindow(TimeSpan.FromMinutes(30),TimeSpan.FromMinutes(1)) where window.StdDev(e => e.Value) > measurableValue * 1.2 select new OutputEvent { Error = "Deviation" }; Thanks in advance!

• Dynamically adding a Button to a PlaceHolder in a DataGrid

  - by hrnt

  I have basically something like this: <asp:datagrid id="DGrid" runat="server" AutoGenerateColumns="false"> <asp:TemplateColumn HeaderText="Stuff"> <ItemTemplate> <asp:PlaceHolder id="PH" runat="server" /> </ItemTemplate> </asp:TemplateColumn> </asp:datagrid> I need to add a Button to the PlaceHolder depending on the values of the data I am binding. At the moment I am adding the Button after the data is bound in Page_Load. The problem is that the data binding methods are not called in postbacks, so the Button disappears when I click on it. Any suggestions on how to do this? Problem is that I need to know some attributes of the grid item to create the Button, so I cannot create it before the data has been bound.

• Drop Down Box (select) set URL on postback?

  - by jamone

  I have a page with a ASP.NET DropDownBox control (HTML select) that's populated with some dynamic record values. When the user selects a record the entire contents of the page is updated to reflect the selection. If a user clicks a link and leaves the page and tries to go back, it pulls up the default unselected list, and they have to reselect it again. How would be the best way to retain their selection? I currently have the page set so if the url contains PageName.aspx?recordID=5 it will select the correct dropDown option. However I'm not sure how to change the URL's query string based on the selection.

• converting a form from text to textarea

  - by David Cook

  I have a form created to pull PHP values into my database. I created the form with all type="text" constructions. What follows is the code that used to set up the input of data and confirmed that it is functional. <label>About Me: <input type="text" name="BIO_info"/></label> I converted the input to a textarea and adjusted some parameters for proper display. Unfortunately, it has broken the ability for the script to function. What follows is the code I wrote to convert and store from a text area input. <label for="BIO_info" style=" margin-bottom: 500px; margin-top: 2000px; ">About Me: <textarea name="BIO_info" rows="20" cols="60" style="resize: none; overflow-y: hidden;vertical-align:middle;"></textarea> <p> I would appreciate any suggestions.

• Relational databases are not suited for my application - what's the alternative?

  - by waitinforatrain

  Hi, I'm writing a CMS in PHP that allows the user to define different fields (e.g. a Blog page could have fields for Title (string), Content (rich text), Picture (file)). I need the user to be able to add and remove fields dynamically, and the only way I can think of to do it with relational DBs is to serialise all these values and store them in one cell. This seems like a slow approach and like I'm trying to fit something dynamic within a static structure. Could someone recommend anything that is PHP-compatible that would make this easier?

• Passing a web service an unknown number of parameters

  - by Billyhole

  I'm relatively new to utilizing web services. I'm trying to create one that will be accepting data from a ASP.Net form whose input controls are created dynamically at runtime and I don't how many control values will be getting passed. I'm thinking I'll be using jQuery's serialize() on the form to get the data, but what do I have the web service accept for a parameter? I thought maybe I could use serializeArray(), but still I don't know what type of variable to accept for the JavaScript array. Finally, I was thinking that I might need to create a simple data transfer object with the data before sending it along to the web service. I just didn't wanna go through with the DTO route if there was a much simpler way or an established best practice that I should follow. Thanks in advance for any direction you can provide and let me know I wasn't clear enough, or if you have any questions.
