I have an IEnumerable as a result of LINQ, which contains Value and Count. After I get the result, I want to do a string manipulation on the Value and make the corresponding Count to half. Is that possible with LINQ?

View 1 RepliesI need to display the first c.200 characters of a longer string, for the homepage of a news website. I am using VB.NET. Obviously, cutting exactly 200 chars quite often cuts a word in half, e.g.: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at regu" I need a function that will produce: "The last five years have seen a radical increase in the volume and complexity of company legislation. The Bahamas has established a Stock Exchange, passed legislation aimed at" I can then add "... [More]" or whatever to the end of this string and voila! Is there any way of using regular expressions (regex), substr or something similar to produce this output?

im working on a small application that lets you input a phone number with "-" hyphens, and then copy that number to a label control minus the hyphens. So for instance 111-234-567 would become 111234567, i have accomplished this using the string.
replace command, however i was wandering if it would be possible to iterate through the string with a for next loop looking for the hyphens and then removing them with the string.
remove command, ive spent nearly 5 hrs trying to get the code to work, but to no avail, no errors are being thrown up, but the hyphens still display along with the number, i am currently teaching myself, and its a sloooooooow process. here is my unsucessful code

I'm just wonderng how I get hold of the @bar.com from the string?

I'm suppose to end up with a label box with my name spelled out in it using string manipulation. This is suppose to happen using the concatenated string to output the name into the label box. I don't have any error codes but I also don't have my name in the label either. [code] "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. [code]
View 2 RepliesSo I have a string "New". What is the simplest way to convert that string to "New". Basically right now I'm doing this:
Case "NEW"
makes = connector.GetMakesByYear(_AuthorizationKey, "NewCar", CDate(Now), Year)
Case "USED"
makes = connector.GetMakesByYear(_AuthorizationKey, "UsedCar", CDate(Now), Year)
And I would prefer not to use a case statement because it's only one parameter that needs to change, and both are appended with "Car".
The idea is simple, if I have a string value "ABCD" then with a ButtonClick event it should randomly reveal a char while others are hidden. i.e, "B*" another click would "AB**" and so on. So far, my I have been stuck in a for loop.

[code] How to substring only the line(s) below the explanation e.g. No match for "VBFORUMSBLAHBLAH.COM". Everything else should be ignored.
View 10 RepliesWhat my program does is load a file (password list), then progressively reads each line of text in the file whilst writing each line to a new file. After X amount of lines have been written, it should start writing the lines of text to a new document until the initial password list has been split into X amount of password lists. The problem I have is that after hours of tweaking, all I can get it to do is write either blank ocuments, or write all of the lines to only one file. I really need it to be able to split into multiple files, preferably at runtime rather than loading a whole text document into the program in a textbox or array then writing it to new files.Below is the source:

So I'm working on a software in VB.Net where I need to scrape information and process it according to rules. For example, simple string replace rules like making "Det" into "Detached" for a specific field, or a split/join rule, basic string operations. All my scraping rules are RegEx and I store them in a database in rows of rule sets for different situations.What is the best way behind creating/storing rules to manipulate text? I do not want to hardcode the rules into the software, but rather be able to add more as there will be a need for them. I want to store them in a database, but then how do I interpret them?

Is there a way to get the fraction parts of a Double without using string manipulations? Specifically in vb.net?
There are numerous examples for a decimal in various languages. One for vb.net is this one
Basically they all seem to use either a mod or Truncate method or they take advantage of casting to integer behavior. But none of those approaches will work for a double/float type due to the inherent inaccuracy of the double/float type. There is also the problem that doubles don't cast to decimals reliably. Below is a test case to show what I mean and expect.

View 4 RepliesVB.NET 2010/ASP.NET 4. I am using a web service which returns a string like this:
US,"UNITED STATES",MN,MINNESOTA,"MAPLE GROVE",45.1234,-93.4947,613,763,AMERICA/CHICAGO,NA,55311,"COMCAST CABLE","COMCAST CABLE",COMCAST.NET,"AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC",CABLE/DSL,RESIDENTIAL,3,99,35,96,,
If I split by comma it's usually fine except in the above string I have the following:
"AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC"
Which contains a comma and splits into two. This I don't want.
How to see if this field (array(15)) contains a comma & if it does to leave it intact into one array field? It's always constant in the same place in the array
Example:
(14) = COMCAST.NET
(15) = "AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS"
(16) = "INC"
(17) = CABLE/DSL
But I wish to keep it so it's:
(14) = COMCAST.NET
(15) = "AS13367 COMCAST CABLE COMMUNICATIONS HOLDINGS, INC"
(16) = CABLE/DSL

I've made a class that's supposed to manipulate strings in a textbox to turn them into integers and let the cursor return to the place it was before a character was removed. It seems to work fine as far I've been able to figure out, but when I use it from the TextChanged event things go wrong. The problem is that when the class is finished and the corrected string is written back into the textbox, the TextChanged event is fired again. That on itself is not the worst problem as it runs too quick to notice, but the disadvantage is that a variable needed is destroyed with the class after it's finished the first time, resulting in the cursor ending up in the wrong place at the left of the textbox after it's run for the second time.I've been thinking of 3 solutions, but none of them I've been able to find out how to put it in code or even if they are possible:
