Searching String For A Character?
Oct 15, 2009
I know this has been answered before but I am having trouble with it still. I am trying to find if a textbox has an "x" as the first character. I am trying to use the left(string, 1) command as described in a couple other threads to just test the first character on the left but the only left function I can find relates to the left coordinates of the textbox.

I have been trying to write code that asks the user for the size of an array , and then takes inputs from the array. They are characters A-E... Then I am to call a function that will count the frequency of A,B,C,D,E . Then it is supposed to send the information to a listbox. Eg. There are 2 A's,There are 0 B's, There are 5 C's..
I have the code for populating the array, but when it comes to searching it for the frequencies..This is what i have so far..

For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.

I've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code:
ABinary = "0110 1100 0001 1011"
For x = 0 To Len(ABinary) - 1

I got this
If File.Contains(Searchwhat) Then
Countnr = Countnr + 1
VinBox.Items.Add(filename)[code]....
That code works great to search for one string, but how can i search for multiple strings in the file? Lets say that "Searchwhat" looks like "GFR,EPB,IKJ" and if the file i am searching in can find all that in the file it will add the filename to the Pathlistbox.

I have a problem when searching an XML string. The problem is that I can't get it to work. I have a big XML in a string, and I only need 2 values that are each in seperate elements. It is hard to explain so it's best I just show it.This is my XML: (sorry it's very long, but I want it to be complete so my question can be answered properly).
<transactions result="1">
<transaction raisewarning="false" result="1" location="temporary">
<header>
[code]....
For each <transaction> I need the value of <Number> that is in <Header> and the value of <invoicenumber> in <line (id=1)> ... I have colored the elements in my sentence the same as I colored them in my big XML?The number of <transaction>'s can vary for each XML (these are a webservice response).I've been looking for 2 days now, and I can't seem to grasp this XML stuff unfortunately.

I want to search for a specific string within a text file, however instead of hard coding these string values into the system is there any way I can have them within an external file such as a text file and have these values that are to be searched in there and then pull them from there?

I need to accum some data based on whether or not an SSN number appears in the data. I have it in a string, what I need to do is search for a numeric pattern within the string such as:I looked into regex a bit, but I don't have much time to read deep into it (my company needs the program this week) and it seems too complex to grasp in such a short time. What I've came across so far is:
If (rec.address1 Like "###-##-####")
but I don't know if this will filter it out of the string (it can appear with an address attached to it).

I'm sure but can't see the answer. Currently going through a string "DO While Not ts_IN.AtEndOfStream" looking for information. This includes then checking another string (while inside the first) for matching reference point for further data.
So within the first loop, I have a second loop "Do While Not ts_IN2.AtEndOfStream". And looping through that string searching for the reference point.
This works initially, but after awhile don't find anything because it is not going back to the start of ts_IN2 string each time loops on the first section.

It seems simple enough, but apparently I cant figure it out. Theres more to my actual problem, but once I figure out this concept then I can do the rest. I want to search a list for a given string, and if it matches, then print it out. If it doesnt match, then it moves to the next item in the list. If if doesnt find any matches, it says "no matches found".

I have a program which grabs the source code of a webpage and puts it into a string. I would now like to search the string for two values.
"video_id": "value 1 here"
"t": "value 2 here"
The problem, is that I don't know the position of the values, and I the values change depending on each webpage. All I know, is the text before the value, e.g. "video_id" and "t:"
Here is my code:
Dim videoid As String = TextBox1.Text.Trim
Dim wc As New System.Net.WebClient()
Dim result As String = wc.DownloadString(videoid)

If ListBox1.FindStringExact(TextBox2.Text) = "0" Then
Label2.Text = "yes"
GoTo procheck

and it searches the first item in the listbox correctly but nothing else. Im assuming im going to need to loop through the listbox somehow?

I have the following simple code for searching for a text string within a folder and have several questions:
Dim searchFolder As String = "C:BakerOrders estOrders"
Dim files As ReadOnlyCollection(Of String)
files = My.Computer.FileSystem.FindInFiles(searchFolder, "NEXT DAY PM", True,
[Code].....
The folder will contain up to 1,000 text files (at any point) at 20kb to 50kb each. The scan should occur every 5 sec with ~200 new files and (-) ~200 exiting files during this period.
Questions: The previous code only catch files from 1 text string. Is there a way of doing one search and returning the files which contain any of the 3 strings? Is there a more effective way of achieving this? Is there a simple / effective way of searching each file only one time by keep track of previous results while searching only the 200 new additions each scan?

This is way out of my league, I can manipulate strings a bit but i'm 1000% stuck how to approach this.
I get page source to a textbox1.text, In the source in contains multiple lines of
window.SC.bufferTracks.push({"id":5528782,"uid":"27XQR7Tk19XD","user":{"username":"Monosurround","permalink":"monosurround"},"uri":"/monosurround/music-to-drive-tanks-to-granite-eyes-monosurround-

Once got, need to add it self to a array then carry on looking for more instances of that type of line
I know this is a lot to ask, but iv spent the last hour googling and comes up with basic string manipulations

i am working on an assignment to search a value in datagridview column if value matched with input textbox then datagrid cursor should move to the cell having that searched vallue and if column has more than one searched values then cursor should move to next cell having that particular searched value and so on .e.g
----------
[code]....
suppose that if we search for value AROUT which is in cell nomber 3,5 and 7 when user hit the serch button first time then data grid cursor should move to the 3rd cell and when user again click search button then datagrid cursor should move to the 5th cell and when user click search button third time then datagrid cursor should move to the 7th cell i have tried many combination with FOR loop and IF condition but with following code i am able to search the string only once obviously if condition does not allow me to search a value more than once .the code is
for i as integer=1 to 90
If DataGridView1.CurrentCell.Value<>textbox1.text Then
DataGridView1.CurrentCell = DataGridView1.Item(0, i + 1)
End If

I've got two text files. The first has got a list of certain keywords. Each one if these keywords are fed into a combobox. Now, when I choose one of the items from this combobox, I want to search the other textfile for the same keyword and read from that point to the next keyword. And then feed each line into a listbox. Perhaps I should use an INI-file for this purpose, doesn't really matter for me.
The textfiles have this structure;
Textfile1:
London
Oslo
New York
Hamburg
Amsterdam
The second textfile has this structure;
Textfile2:
'London'
Apples
Oranges
Pears
'Oslo'
Pasta
Salami
Monkeyballs
'New York'
Dada
Duda
Dadadish
Is this possible? The reason I want to do it this way is to create a fully dynamic system. One which relies fully on whatever information is stored in these textfiles. I'm gonna build pretty complex strings from these results later on. So far, I've got this to read the first file and add each line to the combobox:
Dim oReadMenuFunction as System.IO.StreamReader
oReadMenuFunction = IO.File.OpenText("textfile1.txt")
Do While oReadMenuFunction.Peek <> -1
Dim LineIn as String = oReadMenuFunction.ReadLine()
Combobox.Items.Add(LineIn)
Loop

I haven't programmed for some time, so I'm a little rusty Basically I'm storing HTML within a variable, and I need to count the amount of times a specific element appears e.g. <h3 class=r> for now.
I thought of using a for each loop, and passing the string above into the parentheses of the loop (using a variable ofc) however for many reason's, I don't think this has a chance of working (won't bother explaining why, as I assume you can guess). Then thought of using the .Contains method of the string class, but I simply can't think of how to use it with what I'm trying to do.

There's an INI file that I want to access and read information from. This is the complete content of the INI file in question: http:[url]....I believe it is because of the [ ] tags in that INI file. Because they work if I remove the tags.My program has a bunch of comboboxes, trackbars and checkboxes. These items will be filled by the information taken from the INI file.For instance, ini file has these lines;
bCrosshairEnabled=1
bDoDepthOfField=0
bFXAAEnabled=1[code]...
Example: I want the checkbox8 in my form to get checked if bFXAAEnabled has a value of 1 or unchecked if it is 0.

I am wanting to create a Where statement within my Linq statement, but have hit a bit of a stumbling block.I would like to split a string value, and then search using each array item in the Where clause.In my normal Sql statement I would simply loop through the string array, and build up there Where clause then either pass this to a stored procedure, or just execute the sql string. But am not sure how to do this with Linq to Entity? ( From o In db.TableName Where o.Field LIKE Stringvalue Select o ).ToList()
