Say I have a section of code e.g:
[StringLength(15, ErrorMessage = "Length must be less than or equal to 15")]
public string UserDefinedName0 { get; set; }
[StringLength(63, ErrorMessage = "Length must be less than or equal to 63")]
public string UserDefinedValue0 { get; set; }
Is there any plugin or visual studio feature or third party windows tool that allows me to copy and paste it such that I get a parameter for say "0" when I paste.
I think this is what you are looking for:
Visual Studio Tip: Setting Up Code Snippets with Variable Parameters
I don't know of a plug-in that would do that, but can think of two solutions that might be helpful:
Write a short macro yourself. It's easier than you might think.
Use RegEx replace. Not sure if this will suite your purpose fully, but I have used it so many times to do some clever code duplication.

I am building a program using visual studio C#.
I have a list of figures that are inputted into text boxes.
I need to make a calculation using the highest inputted figure and wondered how I would go about this.
I have been reading a lot of similar questions in this site but not got the answer yet. I am new to programming and still 'self teaching' myself about the language so please go easy lol.
I have these int declared ads1, ads2, ads3, ads4, ads5, ads6
these figures are then taken from a text box (admissions1, admission2 etc.)
I need to calculate a sum using the highest admission number (i.e. the total amount of admissions)
using System.Linq;
...
var arr = new int[] { ads1, ads2, ads3, ads4, ads5, ads6 };
return arr.OrderBy(i => i).First();
This uses the Linq extension methods OrderBy and First.
I've hit a pretty major snag with the entities generated by spmetal / linq to sharepoint. I am hoping someone has dealt with this before.. or maybe I am missing something obvious.
Let's say we have a list with a number field. The field will be expected to hold reasonably precise values.. for example, 0.0000451. Once the value is in the list- SharePoint is fine with it. It displays in the list and display/edit views correctly.
Now if we generate entities based on this list with spmetal, we will get..
//...
private System.Nullable<double> _number;
//..
[Microsoft.SharePoint.Linq.ColumnAttribute(Name="Number", Storage="_number", Required=true, FieldType="Number")]
public System.Nullable<double> Number {
get {
return this._number;
}
set {
if ((value != this._number))
{
this.OnPropertyChanging("Number", this._number);
this._number= value;
this.OnPropertyChanged("Number");
}
}
}
//...
Since the type determined by spmetal is doublewe get notation when trying to retrieve it.. for example:
var number = (from x in myDc.MyList select x.Number).First();
number would actually result in a double of 4.51E-05, not 0.0000451.
I am assuming this can be fixed by using a decimal. If I change the types throughout the generated entities to System.Nullable<decimal> I get type conversion failures.
How should I fix this?
EDIT I think maybe it is better to ask "how should I deal with this"? for example, I can simply convert my double values to decimal later on down the line.. my linq query, for example. If I do that, the example case would return the expected result. That seems clunky, though, and I'd like to correct this at the source.
There are several cases like this where SPMetal will give you clunky code. You can, and sometimes have to, fix that. And I admit, it definitely feels better to do it at the source.
But there is a downside.
When your data model changes you will have to re-run SPMetal to incorporate your new entities. Any changes you made to the generated file will have to be carefully documented and re-done, or your code will be broken. Therefore, I would advise to leave the generated code alone if you can work with it.
If you can write a wrapper around the objects/methods it would of course be preferable to just converting the types at the end-point, but that's general good programming practice.
4.51E-05 actually equals 0.0000451 so there is nothing wrong with your code.
In other words 4.51E-05 means 4.51 times ten to the minus five power, or 0.0000451
In Visual Studio you can minimize huge chunks of code using regions; they essentially just surround the code and minimize it in the window.
Does Sublime have a feature similar to this?
By default, you can select some code the go to Edit > Code Folding > Fold. There are tons of plugins that leverage the code-folding api for more options.
There's a request on the official site to "ask for features" here.
But apparently:
FYI, Jon has stated that this is not possible in the current
implementation of the editor control. Looks like we're waiting till V3
guys.
Jon being the programmer behind Sublime Text 2.
There might be a way to fake it by creating a plugin that looks for markers and removes the code region in between the markers, but it probably wouldn't look good. With the current API, it's probably your best bet!
By the way, there is some code folding in Sublime Text, if you hover your mouse next to the line number, you will see some arrows appearing when you can fold / unfold.
I ended up using custom comment tags, indented one level less than the code I want to fold. It doesn't look best, though it serves its purpose.
class Foobar {
// ...some code
// <fold
function foo() {
}
function bar() {
}
// </fold
// more code...
}
This (at the moment) folds to:
class Foobar {
// ...some code
// <fold[...]
// </fold
// more code...
}
Having a native ST2 support for this would be nice.
This looks what you are looking for. You can define tags for #region and #endregion for each language, or a generic tag for all of them.
If you are obsessed with intendation, this solution may make you uncomfortable but here it is, once upon a time while I had been writing a semi-complex jQuery plugin I've had constants, variables, private and public functions sections and foldings like so;
;(function($, undefined, window) {...
/* Consts */
var FOO = "BAR";
/* Variables */
var m_Foo = "bar";
/* Functions */
/* Public Functions */
function foo() {...}
function bar() {...}
/* Private Functions */
function _foo() {...}
function _bar() {...}
})(jQuery, window);
As you can see it is all about intendation. Sections can be folded; Consts, Variables, Functions. And also inside Functions section, Public Functions and Private Functions are both can be folded.
You can also use one line comment (//) to name your fold. So the idea underneath that is simple; ST2 thinks that the more intended lines belongs to first less-intended comment above them, like C/C++ compilers how handle brackets as own unique code blocks.
To fold the code select the code and press
ctrl + shift + [
To unfold the code put the cursor there and press
ctrl + shift + ]
I think that like myself, the OP has come to appreciate a little-known feature in VS called regions that many equate to code-folding, but is FAR more powerful and above, Dio Phung provided the answer that I wanted, and I suspect the OP wanted, but he didn't share as an answer so here it is.
The difference between "code-folding" as it's provided in Sublime Text is that it's based on code/compiler syntax while "regions" and what this plugin does, allow you infinitely more freedom, though it's a freedom that's more or less dependant on the code you're working with to begin with (deeply nested, or properly modularized).
If you are on Sublime Text 3, here is a plugin that can do it :
github.com/jamalsenouci/sublimetext-syntaxfold – Dio Phung
In languages which support 3 types of comments (e.g. PHP) I use the hashtag comment for regions, as shown in the other answers. It's also good for keeping track of what's being done
# default options
$a = 3;
$b = 'bob';
$old_code = 1;
# bugfix #130
$result = magic_function($data);
fix_stuff($result);
$old_code = $result;
Otherwise use triple slash ///, or //# etc.
In sublime text, it works like this, it shades the lines you want to collapse and presses (Control + Shift +?)
I have the most recent version of sublimetext.
Is there some way to save array/list/collection data to a file while debugging in VS2010?
For example, in this code:
var addressGraphs = from a in context.Addresses
where a.CountryRegion == "Canada"
select new { a, a.Contact };
foreach(var ag in addressGraphs) {
Console.WriteLine("LastName: {0}, Addresses: {1}", ag.Contact.LastName.Trim(),
ag.Contact.Addresses.Count());
foreach(var Address in ag.Contact.Addresses) {
Console.WriteLine("...{0} {1}", Address.Street1, Address.City);
}
}
I'd like to set a breakpoint on the first 'foreach' line and then save the data in 'addressGraph' to a file.
where 'a' contains fields such as:
int addressID
string Street1
string City
<Ect.>
and 'Contact' contains fields such as:
string FirstName
string LastName
int contactID
<Ect.>
I'd like the file to contain the values of each of the fields for each item in the collection.
I don't see an obvious way to do this. Is it possible?
When your breakpoint is hit, open up the Immediate window and use Tools.LogCommandWindowOutput to dump the output to a file:
>Tools.LogCommandWindowOutput c:\temp\temp.log
?addressGraphs
>Tools.LogCommandWindowOutput /off
Note: You can use Log which is an alias for Tools.LogCommandWindowOutput
Update:
The > character is important. Also, the log alias is case sensitive.
See screenshot:
I also encoutered such a question, but in VS2013. I have to save a content of array while debugging.
For example, I need to save a content of double array named "trimmedInput". I do so:
Open QuickWatch Window from Debug menu (Ctrl+D, Q).
Put your variable in Expression and push Recalculate Button
You'll see all the values. Now you could select them all (Ctrl+A) and copy (Ctrl+C).
Paste (Ctrl+V) them in your favorite editor. Notepad, for example. And use them.
That's the simples way that I know. Without additional efforts. Hope that my description helps you!
P.S. Sorry for non English interface on screenshots. All necessary information are written in the text.
Something similar is possible with this method:
I built an extension method that I use in all of my projects that is a general and more powerful ToString() method that shows the content of any object.
I included the source code in this link:
https://rapidshare.com/files/1791655092/FormatExtensions.cs
UPDATE:
You just have to put FormatExtensions.cs in your project and change the Namespace of FormatExtensions to coincide to the base Namespace of your project. So when you are in your breakpoint you can type in your watch window:
myCustomCollection.ToStringExtended()
And copy the output wherever you want
On Visual studio Gallery search for: Object Exporter Extension.
be aware: as far as I worked with, it has a bug that block you from exporting object once in a while.
You can also call methods in the Immediate Window, and so I think your best bet would be to use an ObjectDumper object, like the one in the LINQ samples or this one, and then write something like this in the Immediate Window:
File.WriteAllText("myFileName.txt", ObjectDumper.Dump(addressGraph));
Depending on which ObjectDumper you decide to use, you may be able to customize it to suit your needs, and to be able to tell it how many levels deep you want it to dig into your object when it's dumping it.
Here's a solution that takes care of collections. It's a VS visualizer that will display the collection values in a grid while debugging as well as save to the clipboard and csv, xml and text files. I'm using it in VS2010 Ultimate. While I haven't tested it extensively, I have tried it on List and Dictionary.

In "Immediate Window" print following to get the binary dump:
byte[] myArray = { 02,01,81,00,05,F6,05,02,01,01,00,BA };
myArray
.Select(b => string.Format("{0:X2}", b))
.Aggregate((s1, s2) => s1 + s2)
This will print something like:
0201810005F60502010100BA
Change the '.Aggregate(...)' call to add blanks between bytes, or what ever you like.
I have an overloaded method which have these signatures:
void Method(string a,string b);
void Method(string a,string b,string c);
void Method(string a,string b,string c,string d,string e);
What I want to do in Visual Studio IDE is to find all lines in the current project where Method is called with only less than 5 parameters (e.g. the first and second signatures in the example).
Is it possible to do this (or any plugin resharper etc. is able to that)
Try this regex in the find window:
(Method\(([:a:b]+,[:a:b]*)^1\))|(Method\(([:a:b]+,[:a:b]*)^2\))|(Method\(([:a:b]+,[:a:b]*)^3\))
It's an OR basically of:
(Method\(([:a:b]+,[:a:b]*)^N\))
where N looks for N of alpha or whitespace followed by a comma
You can search with regexp, so you should be able to do something like "/void[]Method\(([^\)^,]+,){1,3}\)/". I don't know if it is the exact syntax, but you have the idea.
