was wondering if anyone could help me find the regular expression for this problem. I'd like to replace the following using Visual Studio 2010's built in Find/Replace function:
_batch.AddInstruction(InstructionType.Update, "LEG_RES_ID", "N")
with
_batch.AddInstruction(InstructionType.Update, BpcFields.LegResId, "N")
The "LEG_RES_ID" is a placeholder, multiple different strings can occur here. For any string in that position, the equivalent member of BpcFields will be a Pascal-case version of the same string, without the underscores, as in the example above.
Many thanks in advance!
I'd look at this answer and try to use macros. It seems that it is not possible to changhe the case of text only with regexp unless you have another editor (for example EditPad pro according to this question).
Another workaround would be to create a program that performs the task you need on text files and use it on your source.

In Visual Studio, is there a way to specify an object type when doing a regular expression find and replace? I'm trying to do a find and replace in Visual Studio but I only want to do it on objects that are of a specific object type (I want to only do this on strings, and not any other object type).
This is my regex query:
FIND: (Me\.(?:(?!.*Exclude).*?)) Is Nothing[^"]
REPLACE: String.IsNullOrWhiteSpace($1)
If this capability isn't built in to Visual Studio, is there an extension or something else I could use to do this with?
No, you can't specify the type of the object in the regex, since it's looking for a string pattern and have no idea of what the string really is.
I would give a shot with ReSharper but I'm not 100% positive that it can do such things.
I've taken over a project that is full of code like this:
if (aTraceUserids[t].Trim().ToUpper() == Userid().Trim().ToUpper())
{
// ...
}
What is - using tool-assisted expression formulation - a good way to do a search replace into something like this on a case by case base:
if (aTraceUserids[t].Equals(Userid(), StringComparison.InvariantCultureIgnoreCase))
{
// ...
}
Edit (thanks Dave for making me think on this further):
I know this should be possible with regular expressions, but those are hard to get right and document, so I wonder about tool assisted ways that help me both phrase the expressions and execute them.
Ideally I'm looking for a pattern based search/replace tool that allows me to
enter the search/replace patterns
enter the patterns for the files and directory names to match
visually assists me with the search/replace matches, and allows me to post-edit each occurrence
I don't care much which platform as these kinds of search/replace actions will likely apply to other big code bases as well.
So: any solution based on *nix, Windows or web are fine. CygWin and/or WINE based solutions are fine too. (That's why I removed the VS2010 tag and added some platform tags).
Since this was originally tagged with 'Visual Studio', Visual Studio itself can do regular-expression based find/replace, and the standard 'Find and Replace' dialog will let you pick and choose by hitting 'Find Next', 'Replace' or 'Replace All' as you choose.
For example, I recently changed an API from;
Log.Error(string message, bool someotherArg);
to
Log.Error(string message);
And easily used Visual Studio to replace all usage throughout my codebase of this modified API like so;
Find what;
Log.Error({.*}, true);
Replace with:
Log.Error(\1);
The backquote in the replace line \1 puts the grouped regex contained by {...} into that spot in the replace.
Handy, and built-in. Works for me.
I have a situation where i need to search for couple of objects in my code files. currently i m doing it by seaching using visual studio search option for every text i want to search.
I want to use regular expression ( search -> use -> regular expression ) to search all my text at once using OR operator.
Please suggest me for that, as i am not much familiar with regular expression syntax.
Sry for editing in question itself..
I got the answer. Like if I want to search for objects 'abc','xyz' I would put abc|xyz in visual studio seach box. But i don't know how to make this search case insensitive. I got a hint of using /i or -i or ?i , but where and how - i don't know .
As far as I know, Visual Studio should search case insensitive, unless you check the box that says "Match case" (see screenshot).
You can use the alternation operator | to effectively OR part of the regex. So (foo)|(bar) will find either the text "foo" or the text "bar". Either side, can of course, be a regular expression on its own, so you can come up with some pretty complicated stuff.
But as zzzzBov said, if you want any more help you're going to have to supply more information. Or you could actually, you know, read the documentation.
I've found that the search in file using regular expression is buggy in regard to case sensitivity in Visual Studio 2015. Even with the "Match case" option turned on, it will match text ignoring case by default.
The one trick that somehow fixed this is by using capture, surrounding the literal text you want with parenthesis in addition to the "Match case" option!
So instead of: abc.def
Use: (abc).(def)
I have a large solution with a lot of lines that I need to replace.
In Visual Studio, you can search and replace with the aid of regular expressions.
I want to replace lines like:
rst.Fields("CustomerName").Value
rst.Fields("Address").Value
rst.Fields("Invoice").Value
To:
row("CustomerName").ToString()
row("Address").ToString()
row("Invoice").ToString()
Thus keeping the dynamic text part, which can vary.
Is this possible and how?
Update, solution:
Search: rst.Fields{\(.*\)}\.Value
Replace: rst\1.ToString()
Thanks JaredPar!
Try the following
Search Expression: ASpecificCommand(\(.*\))\.ASpecificProperty
Replace Expression: ATotallyDifferentCommand\1.ATotallyDifferentProperty
Note: This is not a perfect solution. Since there are (s involved and hence matching of nested parens, a regex won't ever be a perfect solution. However it should get the job done for the specific pattern you posted
The answer and solution provided helpful in doing a find-replace on messageboxes.
This worked in Visual Studio 2008 (VB .NET):
Example:
MessageBox.Show("Invalid Entry","Error")
Find What:
MessageBox.Show{(.*,*)}
Replace WIth:
Error.ShowError\1\2
Results in:
Error.ShowError("Invalid Entry","Error")
Looks like you have it nailed. It's what is called a "tagged expression" and you can see another example here:

I'm looking for a decent tool that can do search and replace over multiple files, with regular expression syntax I'm use to in C#. Normally I would do this in Visual Studio, except it has the strangest regex syntax (and this is meant to be faster than just replacing the text in the files manually).
So far I've tried windows grep but it didn't like the regex below. The regex in question is
<see cref="(?<class>.+)">(.+)</see>
To replace with
<see cref="${class}"/>
Alternatively converting this to Visual Studio's syntax would be fine!
Jeff has a whole post on this on his blog.
In Visual Studio, find:
\<see cref="{:i}"\>.*\</see\>
and replace with:
<see cref="\1"/>
{} is the VS grouping operator. It is not named. In replacements \n is used for the value of the n-th group in the find expression.
You can tweak the :i and .* parts if you need to account for new lines or other whitespace.
In Visual Studio you can do this with the following Reg Ex:
\<see cref="{.+}"\>.+\</see\>
Replace:
<see cref="\1" />
Remember to select Use/Regular Expressions in the Find and Replace dialog.
I've long been thinking it sucks that Visual Studio does not support the same Regular Expression syntax as the .Net framework.
There are a few choices:
If it's something you do regularly, I would go with PowerGrep as it is probably the most complete and user-friendly tool for this.
Its sibling, RegexBuddy also has a Grep functionality, albeit not as comprehensive.
If you're not afraid of Perl, you can also use its command line as a search and replace tool.
Otherwise, there is still the venerable sed that works on Windows.
notepad++ is quite popular and lightweight and has this functionality, have you tried that?:

EDIT:
It would appear my link is outdated and this usage is only quite recent:

You can use the .NET Regular Expression AddIn to allow you to use .NET regexes with Visual Studio. It's on CodeProject at http://www.codeproject.com/KB/macros/VS2005RegexAddIn.aspx.
