VS 2010 Parse VB/C# Code Files?
Sep 5, 2010
I am creating a kind of 'lightweight' visual studio IDE, basically a text editor for VB or C# code files, or in other words: a visual studio IDE without all the fancy stuff like actually running projects, debugging, form designer, etc. The idea is that you can view and edit code source files quickly and easily without having to start visual studio itself. I often find myself opening source files in notepad when I just want to take a look at something quickly, or to type some code that is intended to be posted on this forum. I find it too much 'work' to fire up visual studio on those occasions, but it would be nice if I had some basic syntax highlighting (already have that), Intellisense and such.
What I'm trying to do now is parse a VB or C# source file to extract information such as the types/classes in a file, and the members (as well as their parameters and return type) in those classes.I was going to do this manually but I doubt I could pull it off efficiently (if at all), so I started thinking about it and thought maybe .NET has some built in functionality already. I don't know much about this stuff, but I do know that you can compile source code by feeding it a string that represents the code. So if it can 'compile a string', then surely it should be able to parse it as well? With the difference between compiling and parsing (I'm not sure if I have this terminology correct) I mean:
- compiling: reading the source and converting it to the CIL so it can be run
- parsing: reading the source and extracting classes/members info, so that the IDE can do some basic error checking (undeclared variable warnings etc) and display the members in a class (in those comboboxes at the top of the code editor for example).
I don't need to compile the source (I'm not going to run the application), I only need to parse it.I would assume that I could call some function that would return a collection of types (Type), and from that I could figure out the members (MethodInfo, PropertyInfo, etc) and their parameters, return types, etc. And all I should give it is the source code as a string.

Wondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

I am having a question on parsing XML files. In my local folder c: estrdl, I have a bunch of xml files.... what I want to achieve is to extract the contents between <commandtext>. The extracted information is basically a SQL query.... Next step is to extract the FROM Clause from the query and save that piece of information into a file with the same of xml file and suffix is "FROM", for ex, if the xml file is called abc.xml, the extracted piece will be called abc_FROM.txt....

I need to parse a file but the data is in a strange format that I'm not familar parsing.
The data is always formatted like this. The field name is to the left and the data is right of the "=" and all fields are always in this order.[code]...
Is there a more elegant way to handle parsing files like this?

I have a directory full of .txt comma delimited files arranged as shown below. What I want to do is to import each of these into a SQL or SQLite database, appending each one below the last. (1 table)... I am open to C# or VB scripting and just not sure how to accomplish this. I want to only extract and import the data starting BELOW the 'Feat. Type,Feat. Name, etc' line.
These are stored in a mynetworkdirectorystats folder on my network drive. Ideally I will be able to add functionality that will make the software/script know not to re-add the file to the database once it has already done so as well.

I am trying to create a sort of code library in visual basic where the form displays a list box of certain project files in vb that i have made in the past and when clicked, launches the .exe files of those visual basic program project files.I know it does not work the same way as writing/ reading text files to vb and it seems as simple as 'on click, launch .exe of selected string "vb program 1" and so on. I am having trouble getting started on this one. Im sorry I cannot provide any starter code bc I only have a basic understanding of in/out text files which wont work the same way with .exe

I'm trying to parse some XML (html) I downloaded using WebRequest.Create() and then read it. However after loading the XML file using LoadXml(string), anything else I execute doesn't work. Setting a breakpoint on anything afterwards doesn't work and it doesn't break.I tried catching exception but none are occurring, so I'm not sure what the problem is.
Here is my code:
Dim reader As StreamReader = New StreamReader(HTTPResponse.GetResponseStream())
Dim xDoc As XmlDocument = New XmlDocument()

I just want to parse simple expressions like IIF(FVAL(PFC) = TRUE, (IIF((ORGVAL(BAS, "2012/12/31") + ORGVAL(DA)) < 6500, (FVAL(BAS) + FVAL(DA)) * 12%, 780)), 0)`After parsing this I should be able to know what functions contains what parameters.

I'm stuck with .Net Framework 2.0, so no Linq or lambda expression goodies for me. Also I want to include the code in my custom library and not just reference it. Can anyone point me to some good library or code.
I just need to parse and not evaluate the expression and find what tokens are in use. After finding the tokens I need to change the expression string before parsing, like if the function ORGVAL is used then the parameter passed has has to be prefixed by an underscore. Like ORGVAL(BAS) will transform to ORGVAL(_BAS). Some functions can have tow parameters like ORGVAL(BAS, "2012/12/31") and this will transform to ORGVAL(_BAS, "2012/12/31")
NOTE: IF THERE ARE OTHER WAYS OF DOING IT PLEASE LET ME KNOW. I WOULD LOVE TO AVOID A PARSER AND LEXER.

I am using this code to parse an html file for image locations:
Dim htmlDoc As String = IO.File.ReadAllText(path, System.Text.Encoding.Default)
Dim Regex As New System.Text.RegularExpressions.Regex("img.*srcs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))")
[Code].....
How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.

I would like to ask some questions related some functions i want to make in my program:
1. I am using this function in order to get a the item code from the database Long.Parse(myReader(0)).ToString("2200000000000") the result i get is: 2200000059091. The form that i want the resultset is
22 (fix value) + item code (6 characters right justified) + 00000 (fix value) 2205909100000 how should i change my code to obtain this result?
2. The programs every time it runs creates a text file which i also attached it plu1.txt, when i try to open it with notepad i see all the lines justified, on the other hand when i open the text file with Wordpad or ConTEXT the lines are not fixed, others are longer others are shorter? What should i change in my code in order to have every line fixed lenght... The code i am using is the following
Dim myReader As SqlDataReader = myCMD.ExecuteReader()
Dim fNextResult As Boolean = True
Using myWriter As IO.StreamWriter = New IO.StreamWriter("c:everest
[CODE]...
3. third and last question is that my program every time it ends show up a pop up menu which says "Text is created." Instead of this i would like to create a file lets say log.txt and every time the program runs, it will overwrite on the log.txt file a line like this: system date + Text is created + with X lines (where X are the lines of the text plu1.txt) ex. 26-10-2009 14:56 Text file created with 15 lines

I had a weird series of errors involving e.Graphics.DrawString() when painting a panel.I am using a barcode font [Code 128] with a library that converts text to the proper format for Barcode readers.That's fine, however, when I draw it to the panel, that's where things stop being fine:But, here's where things get funky. When I put it into a TextBox instead of drawing it via Graphics.DrawString(), everything is peachy:In fact, the TextBox one looks much better than the Graphics.DrawString() one!

My problem: I want to share it with friends and it is just a verry little program ( a n internet radio) so i want it to be 1 .exe with out any other instalation needed so i can easly share it to anyone who wants it. when i make an even smaller program and Debud->build it, it is only 1 exe and no instalation needed. so is there a way to make my program to 1 exe only?
