Cutting Off Digits And Rounding Up/down?
Jul 22, 2010
I need a function that takes a decimal, with a certain number of digits behiond the comma and convert it to a string with a different number of n digits behind the comma. (to display it)My problem is the rounding ip/down.
like 123,789 with n = 2 --> 123,79
or 123,4 with n = 0 --> 123
or 123,5 with n = 0 --> 124
I did not find an existing function that does that, so I wrote one myself.However the code has become soo complex and it still does not work well, and I get frustrated to spend soo much time with something so trivial.Does anyone know a function that can do this? There must be something out there.

I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

Builting a calculator. I have a string of two numbers separated by an math sign. Knowing the length of the first number then adding one for the sign will produce the start length of the second number. Trim the original string to get what I need.
dim num(25) as double
dim length,length1 as integer
dim string, string1 as string
length = Len(num(n - 1))
length1 = length + 1

Basically, I have an Access database with Primary keys that are structured with this format ("02"000).When I try to paste the number, it ignores the "02" and goes straight to 000.For example, here is the code;
PeriodRoomID.Name = ("R" & ds.Tables("sqlSpecRoomRequest").Rows(i).Item(1))
What PeriodRoomID.Name should be is R02001.What PeriodRoomID.Name comes up as is R1.It ignores the "02" and ignores the 0s. This makes sense mathematically but it is not what I want. I need a way to get the exact output and not some simplified version.
The query;
SELECT SpecialSoftware.SpecSoftID, SpecialSoftware.RoomID, SpecialSoftwareNames.Description, Rooms.Capacity
FROM SpecialSoftware, SpecialSoftwareNames, Rooms

I must input a letter and a number in a text box.. say "A14", and them I want to cut the string into "A" and "14" and then use these, but I do not know how to code this as the next string could be "A1" or "C110" and these change... could I make an if for each one? like an if for when its 2 characters and just cut it in half and then an if when its 3 characters and cut between the 1st and second and so on?

I 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?

I have a large wikipedia dump that I want to cut into different files (1 file for each article). I wrote a VB App to do it for me, but it was quite slow and crapped out after a few hours of cutting. Im currently splitting the file into smaller 50mb chunks using another app but thats taking a long time (20-30 minutes for each chunk). I should be able to cut each of these up individually if I do this.
Does anyone have any suggestions of a way to cut this file up quicker?

What are the different methods for injecting cross-cutting concerns into a class so that I can minimize the coupling of the classes involved while keeping the code testable (TDD or otherwise)?
For example, consider if I have a class that requires both logging functionality and centralized exception management. Should I use DIP and inject both required concerns via an interface into the class that requires them? Should I use a service locater that I pass to each class that will require some cross cutting functionality? Is there a different solution altogether? Am I asking the wrong question entirely?

I want my Richtext box to be populated with a text string that contains HTML-style tags to set colour, underline etc.When I try to remove the tags using .cut(), the first cut always works, the second cut only sometimes.Here's a sample to test it:Create a new project and add a button and a richtext box.Add the following code:
Code:
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim testString As String = "ABC<R>DEF</R>GHIJKL"
[code]....
This code works fine.The text between the tags is turned red, then the tags are removed.Now rem out the msgbox line and run again.Sometimes it works, sometimes the second cut fails with no message or warning.I am using Visual Basic 2010
Visual Studio 2010 v 10.0.30319.1
.NET framework v 4.0.30319

I have a long string that I need to parse into an array of strings that do not exceed 40 characters in length. The tricky part of this for me is making sure that the regex finds the last whitespace before 40 characters to make a clean break between strings since I don't want words cut off.

I'm working with the graphic designer in Visual Basic 2008 Express Edition. I tried to cut and paste a groupbox and the variables reverted to standard ones (CheckBox123 etc.), and when I tried to change them back to their proper names, I got an error message stating that this name is "already in use by another component". But this is nowhere to be seen anywhere in the "Form1.vb[Design]". How do I either get rid of these "hidden" variable names or reunite them with the groupbox they used to belong to?

Does anyone has a sample code or idea for cutting and adjusting a picture size when it is uploaded thru picturebox?
For example..
1. Picturebox size on winform = 150*150
2. A picture size = 1024 *800
3. I want to be able to cut 150*150 out of 1024 *800 and upload it. I wish the cutting and adjusting size is possible thru winform.

Basically i work as a desktop support officer. our team does everything from fixing software errors on PCs in the office to moving them from one desk to another. When we do have to move anything though, it needs to be tracked so that our records can be accurate. To track where things have moved to, we have to:
1. fill out a form in an excel format and then fill out the same information into a text file format, and then attach both formats to the job record in our job listing system and send it to our hardware tracking team.
2. If an asset is being taken away to storage, but is considered to be too old, it needs to have an excel table filled out to create a 'disposal' label, or it can create a 'redeploy' label if it still has some years left in it.
3. If we are putting out a brand new asset, it needs to be updated on our tracking sheet to show that the asset is no longer in our storage as brand new.
This obviously creates a lot of administration work for our staff, so i have built my program to take all the information required once, and then split it off to the forms and labels as required.The part I'm stuck at is number 3. I have been working with the excel files in the following format:[code]What i need to do is as the title suggests, search an excel work book (the user will point to it) for the Asset Number in a particular sheet. Once it finds the asset number, cut the entire line out of the sheet and paste it into a different worksheet at the next empty line with a few edited values.
