I am building up an SQL query in VB.net and have written a routine to do it dynamically. I want to include each item in an array (of unknown size) in the where clause, as such:
Dim person(10) as String
Dim strSQL, strWhereClause as String
person(0) = "John"
person(1) = "Steve"
[Code]...
The problem here is that there is an extra " OR " at the end. Is there a neat way of removing this? Or perhaps a better way to approach the problem all together. (I think a string.join will not work in this situation, because there is text before and after the array item.)EDIT: Manually removing the final three characters like so:strWhereClause = Left(strWhereClause, strWhereClause.Length - 3) is fine, except it doesn't handle the empty string. After all, I don't know how many elements will be in my array.
I have a simple question about string concatenation. Following is the code. I want to ask why s6 = "abcde" and not "akcde"? I have change the s2 value to "k".
Public Class Form1 Public s1 As String = "a" Public s2 As String = "b"
when i clicked the final button to display my results "as string" it still showeed the number?? here is the code i wrote, is relativley simple, but the theory doesnt make scence to me Basicly its a box with 3 lables, (first name, surname and age), 3 text boxes (for the user to input this info) and a button at the bottom called "display in message box" so when i click the button, it displays the users input in the form as a message box. [code] what i dont get is if i said to VB that vaiable "Complete" was STRING then howcome it still displays the AGE which is an Integer (a number) not a string??
I had a quick question. I'm desiging a program that users can enter a currency (dollar amount) in a textbox. Since the string I declared will be based on what the user typed in and I want to convert it to a decimal, I want to remove a "$" sign if the user made one.
I'm trying remove non-letters from this string I have. I have an order form for hats and T-shirts, they select everything and click on buy button there order info shows up in a listbox. For the results in the listbox I break down there order info and show there total price. Well the string I have for the sizes comes up with Medium "7 1/8 - 7 1/4" in the list box. I want to remove non-letters and have it just show "Medium". I try using the instr function and the trim function as well but nothing is happening.
Alright I am taking an XML file which has a bunch of tags and I'm trying to eliminate everything but whats inbetween certian tags for instance the input maybe
unless they say they are safe. Average consumer can protect themselves>not knowledgeable enough to always protect selves</w:t> I want to go through and remove those end tags but when i used the remove string it didn't let me specify a string to remove it the two arguments were where to start and how long. how do i specify what to remove?
In the following examples, underscores represent the spaces:
Quote:
_x-xx-xxxx_x.xx.xx_xx
I need to remove just the first space. Now, i tried just replacing the space with nothing, like so:
VB.NET
If s.Contains(" ") Thens = s.Replace(" ", "")End If
But, that removes every space. I also tried .StartsWith, but it still removed every space. I didn't actually expect that to work, but if I hadn't tried it, I wouldn't have actually know.
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:
I need to be able to pull a list of reference from a database whixh ar 12 characters long. Unfortunatley i dont want the first character from each reference number as it is useless but just has to be there.
anyway of saying "list refernce numbers, not including the first character"?
Im trying to remove all text before "Informations here" this is what i currently have.
dim mychar as char () = {"<"c, "s"c, "p"c, "a"c, '....thatandlike20moretill.... "e"c, """"c} string1 = string1.TrimStart(mychar)
(Note that each letter or symbol inbetween the quotations is a part of the string (span = "s" "p"...)Now this works. Not all the time though and its a pain in the .. having to do "letter"c, all the time.. (I got over 10 strings lol) Im wondering if theres a way easier method to remove part of string from the beginning, maybe like still a certen part of the length..
I wrote a palindrome earlier for a project which I figured out but I talked to a friend in another class and he was having issues with how to take out the punctuation. I dont think it was required on mine but I am just currious how that could be done using commands such as str.lenght, or str.trim those basic commands. Here is my last post that is related
I have a string like FVAL(XXX)="TRUE" AND FVAL(TT)="FALSE"
I want to replace all "TRUE" and "FALSE" by TRUE AND FALSE. Now the resultant string should be FVAL(XXX)=TRUE AND FVAL(TT)=FALSE
Will the code shown below be upto the mark for this. Regex.Replace("FVAL(XXX)=""TRUE"" AND FVAL(TT)=""FALSE""", "[""]TRUE[""]", "TRUE", RegexOptions.IgnoreCase)
So im trying to do a simple system in my VB Express Edition 2008 and what it does is add some car models (example) to a list box and stores it in a .txt file for future use. But when the user clicks a delete button it should delete from both the listbox and the .txt. I have to use only the FileOpen(OpenMode.Append or OpenMode.Input/Output) functions.

this is driving me crazy , I have a string like this dim s as string = "<a href="url.aspx? target=_BLANK>mik, H</a>" I want to remove "mik, h" from the string, how can i do that?
I need to parse an alphanumeric string leaving the characters "0-9", ".", "/" and space & remove everything else. I use "[^0-9./ ]" as my regex string and it works well. But now I have a couple other conditions that I dont know how to handle with my regex string. I actually only want to keep the "." character if it falls between two digit characters (ie. 3.5), otherwise remove it. And also I need to replace any "-" characters with a space if it falls between two digit characters (ie. 2-1), otherwise remove it.
I have a file location as a string. How can i remove the path from the string and just use the file name? For example:c:filesfile.zip - is the stringhow can i just make it so it's file.zip?keep in mind that the location is found by using anpenfiledialog(), so it needs to be able to remove the location wherever the file is.
I have not had much time to go threw my code properly as this is some urgency. I need to remove line 1 from a textfile if it contains a string but its not working.I have 500 files and not going to do this manually.
Code: Private Sub btnRemove_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRemove.Click If String.IsNullOrEmpty(txtDirectory.Text) Then OpenFolderDialogDirectory()
[code]....
I also feel the function is very pointless sime i am opening the file twice.
I have a textbox and the text inside is "2 32 52 14 65". May I know how can I remove all the last spaing until it reach the last string which make it look like "2 32 52 14 65". The number of last spacing might change so i can't use the below code where the number of last spacing is known. TextBox5.Text = TextBox5.Text.Substring(0, TextBox5.Text.Length - 3)
