Achieve CSS With Constant Values , Arithmetic And String Manipulation?
Mar 30, 2012
When developing ASP.NET websites (using VB.NET web forms) - a lot of my time is spend writing CSS files and they always seem to get messy (code duplication) and very long.
All I want to achieve is to be able to manipulate the CSS using VB.NET code in the following ways:
Use an integer variable to store my "golden" number 7 and use that for width, padding, margin etc where needed
Use string variables to store my "golden" hex color codes e.g. "#44C5F2" and use them for color, background-color, border-color etc. where needed Use an integer variable to set the height of an element and have four child elements each with height: mynum / 4
I just want to use basic VB.net number and string manipulation in order to create a CSS file on the fly.
I understand that the end product - the CSS file shouldn't change much - it should at most change on a daily basis otherwise caching couldn't be used.[code]...

I must convert string data from a CNC that is arithmetic expression to a number that I can use in a VB application that I wrote. The following is what I get out of the cnc. [18722*65536+19377]/67108864. I need to evaluate this expression in my VB ap. The format of the string is not always the same as what I have illustrated.

I need to know the IOCTL constants for the various strings (for example the value of the constant of IOCTL_ATA_PASS_THROUGH). Searching the net I found that those constants are defined in the header Ntddscsi.h but those constant are wrong. For example the constant value of IOCTL_ATA_PASS_THROUGH should be 4D02C while in the header file it is 40B
The question is: where can I find a list with ALL the right values?
I've found [URL].. where there are listed all the codes. the value in Ntddscsi.h is not the "final" value

I have the following constants declared:
Private Const LuxuryRate As Double = 74.84
Private Const FullSizeRate As Double = 48.44
Private Const MidSizeRate As Double = 44.91
Private Const CompactRate As Double = 30.46
And a combobox that lists each option. How can I set an if statement that uses these values if the option is chosen from the combobox? This is going to be part of a calculation performed when the button is pressed.

I am building an equation parser, it takes the equation
"( 3456 + 321 * X ) / 45"
For example. As I couldn't find a direct solution to parse this equation, I split the equation and started implementing the operations 1 by 1 until I stuck with the execution order of the arithmetic operators (as the multiplication should be performed before the addition). So I am trying now to avoid this and try to parse the full equation. Is there a way to convert the string "+" to + for example?

We are using a custom API in our project which provide an attribute for class fields/members which lets the interface to present a popup of some range values like "On/OFF" and pass the corresponding values of the choice to our code. The attribute requires a string array to know that values.We have many enumerations defined for these ranges,We are thinking to use Enum.GetValues() kind method to get a string array for this method.However, As we know the field declaration do not allow dynamic values in the declaration? so is there any other of doing same thing in efficient way.To clerify the problem i will write the examples below;
Current Working
<RangeLookUp("On:1","Off:2")> Public ASimpleRangeVariable As Integer
While I wanted to do like this or kind of
<RangeLookUp(SomeMethod())> Public ASimpleRangeVariable As Integer
Public Shared Function SomeMethod() as String()
'use Enum to get all the items as string values forexample Enum.GetValues & enu,.GetValues [code]....
Where SomeMethod suppose to return string array to be passed in the RangeLookup constructor.Which means if we change enumeration then we don't have to update the declaration.i know there are better ways to do it but due to some custom API, the ground is limited.

I'm stumped with something I thought I had been doing fine for months now. I get the error, "conversion from string '''' to type 'Double' is not valid."I've also tried to Dim the variables within the private subs with different names and whatnot. I've commented out the TextBox10 and have decided that the error has something to do with me reassigning the textbox value to a variable.

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

This is probably quite a simple question, but I can't remember how to do it off hand.I have an e-mail address of "foo@bar.com".I want to grab the @ and everything after it and then I'll be adding a prefix to the front of the address as I go.
I'm just wonderng how I get hold of the @bar.com from the string?
I know I should know how to do this as this is a really simple operation.

I have strMyColor = "Red".I would like to make lblMyLabel.BackColor to be red.Without using a variable the code would be this:
lblMyLabel.BackColor=Color.Red
I tried using the variable like this: lblMyLabel.backcolor="Color." & strMyColor
But the error is that a string can't be converted to System.Draw.Color. I understand that, as the string "Color.Red" is not the same as the VB constant Color.Red.Is there a way I can construct a valid vbConstant from a string?

When I try to remove the last few characters of a string, I get an index out of range error. I am using the following to remove the characters from the end of the string:
objJSONStringBuilder.Remove(objJSONStringBuilder.Length - 1, 6)
The string has <hr /> at the end which I want to remove.

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]

So 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.

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?

I thought you could use a structure as a container. I have line_1 with a line of data read in from a file. I only want to Look in position 1 of the line and position 8 for 9 and position 31 for 11. If I create a line_2 with the parts broken out for pieces that I want to look at then I could use a with statement right?

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.

Public Class BasicNumberTests
Function DecimalFractionalPart(ByVal number As Decimal) As Decimal

VB.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
