I am working on a function that returns an array of variable-length strings that have a certain starting and ending delimiter. The input to the function is a string. I am able to do this by using if-then statements with InStr(). I was wondering someone knew of a more elegant way. I tried using the split command but I am splitting on one delimiter so I don't really get the result. I could then parse from the results but I am back to the same boat with using InStr().
how to achieve what am trying to do below. am trying to have a set of numbers in different list into and array. so i can select any list in the array as random and get the values in the selected list.
Dim list1 as New List(Of Object) Dim list2 as New List(Of Object) 'adding items to list 1
I have an arraylist that holds a subset of names found in my database. I need to write a query to get a count of the people in the arraylist for certain sections i.e. There is a field "City" in my database from the people in the arraylist of names I want to know how many of them live in Chicago, how many live in New York etc.
how I might set up an sql statement to handle this. I think somehow I have to pass the subset of names to sql somehow.
Here is a sample how I am writing my sql in my code
Public Shared Function GetCAData(ByVal employeeName As String) As DataTable Dim strQuery As String = "SELECT EMPLID, EMPLNME, DISP_TYPE, BEGIN_DTE FROM Corr WHERE (EMPLNME = @name)"
[Code]....
I need a way to create a function using your sql statement to return a datatable object of names and the parameters would be city, and the List of names.
The above example isnt the sql I am looking for its just a skeleton of what the function would look like that I want to create.
So then you would use the function by iterating through all the cities passing in the same set of names each time in the fron end.
I have a list and I need to output each subset of the list for example a b c d e would output to

I believe the correct term is combination no element should be duplicated on the same line I was going to attempt this with a series of loops but im not even sure wehre to start
I am working with the MP3IDV1 class from this link: [URL] I am pulling the ID3 tags from music files, and this class returns the Genre in number form. However, it has the property Genres with that entire list.
I have an array of objects I get from a web service. The 1st element in that array is meant to be displayed in a asp.net literal control. The rest of the elements are meant to be bound to a gridview.
If I have code like this (C# or VB.Net does not matter)
Dim e As IEnumerable(Of XElement) = _ From s In _dataSourceSettings.Elements _ Where s.Attribute("name").Value = toInsert.Attribute("name").Value If e.Count > 0 Then e.Remove() End If
How do I get now new _dataSourceSettings without element that I removed?
I have a simple VB.Net Form that acts as an interface to a control library with a public API.
One of the API calls takes an Array of UIntegers ByRef:
Public Function Get_Values(source_id As Byte, first_value_address As Byte, number_of_values As Byte, ByRef valuesOut As UInteger()) As Integer
After the call, valuesOut will hold a list of values number_of_values long from source_id starting at first_value_address.
There is a hardware driven limitation that the max number of values returned is 15 regardless of requested length. I need to get 28 values into an array from my VB.Net code.
Is it possible to send only part of an array variable to the function similar to this C code?
uint[28] values; Get_Values(0, 0, 15, values);//get first part Get_Values(0, 15, 13, &values[15]); //get second part of data
Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"
Private chequeColl() As Cheque For i = 0 To m.Length - 2 chequeColl(i) = New Cheque()
[Code]....
I now want to make chequeColl only contain those items where Status is not equal to 41. In LINQ this would be easy but I can't think how to do it.
I cannot use the .Net 2.0 LINQ bridge products, I have to do this the old school way. At the end of it chequeColl must only contain those items that are not status of 41. I cannot have empty elements.
I have populated a dataset from a text file and I can display it in a dataview. Can I and if so how do I, select a sub set from this dataset and display it in the dataview?
The program is to take an entered string then search for a subset of letters entered through and input box.In my subprocedure Sub btnSearch_Click I am using a loop to move through the entire length of an entered string to search for a set of letters entered through an input box. I can find the set of letters to search for but instead of increasing my counter "Found" for every instance of a match it returns the length of the string instead. I just don't know why the IF doesn't prevent the counter from increasing for every element in the string. I want the counter to increase only when the match is found. I just put 2 message boxes in there to make sure it found the right letter and then display the counter.

I have a set of x, eg 288, data values. The user wants to fit a regression to a subset of this data, eg (2 - 200), then she wants to analyse within a subset of this fitted range, eg at 20 and 100. So, on my form are four Hor. Slider Bars, to set the lower and upper bounds to the fitting and the analysis. The two that set the lower bounds work fine. The two that set the upper bounds are getting corrupted somehow outside of my code and I do not know how to solve this problem. What happens is that when I click on the right hand arrow on the slider bar, the program runs through my function with the correct values whilst the arrow is down, goes out of my code and then immediately comes back into my code, but with the wrong value set into the Hor. Slider Bar fields that I am working with, eg the .Value field. The new value is always 9 below the maximum that it can be, but I can see no connection to this number.
I am concerned that this code is copying bytes into a temporary buffer before writing directly to file.
I feel like there should be some method of copying bytes directly from the tail end of the main buffer directly to file.'this code copies all bytes starting at integer index from the main buffer into a new file: ga.exe
'declare temporary buffer Dim EXEBytes(bytes.Count - index) As Byte 'copy subset of bytes over, starting at index System.Buffer.BlockCopy(bytes, index, EXEBytes, 0, bytes.Count - index) 'write bytes from temporary array into file File.WriteAllBytes(Server.MapPath("/BIN/ga.exe"), EXEBytes)
I'm working in VS2010 on a visual basic application. It takes in serial port data, writes it to an access database, and then graphs the data.The data only comes in once every minute, so it's not like I'm building an oscilloscope. Right now, the chart is reading from the database using a table adapter and graphing just fine, so long as I keep the number of records in the database low.If I add too many records to the database, the chart shows a red "X" through it. I've played with changing the axes, but it is still a problem.I don't really need to graph the whole database.The twenty most recent records would suffice.How can I make a chart series with only a small subset of the database in it.Perhaps it cold be populated with a query?
I need my code to be able to read from the file to check that the username and password exist and that they're correct and then it'll log them into a customer details page where the details they entered at registration appear for amending/changing.
I was hoping I can make a program which can replace a hex code of a file if it match the code I'm searching in another file. For example, I need to find hex code "1F 7C" in file.ojs and then replace all the "1F 7C" with "E0 03" in test.bmp.
At my old job we used batchscripts to start macro's in another application. These batch scripts would also write data about the status of the macro as loglines to a log file using VB.
I have saved the batchscripts when I moved to another job because I always thought they might come in handy. However I forgot to save the visual basic script needed to create and fill the logfile.
The batchscript would look like this: SET SP=C: est SET LOGFILE=C: est est.log cscript //nologo %SP%logging.vbs "Script executed by admin" >%LOGFILE% cscript //nologo %SP%logging.vbs "Starting Loading Data" >>%LOGFILE%
I've been working on my A2 Computing project for the past few months - and was working on one form.My computer crashed (for some unknown reason) and subsequently the form no longer works.
I can open up the designer for it, and see all the declarations - but I can't open the source code.[code]...

I have a script file which uses code similar to the C# language, using { and } braces to start and close 'blocks' of code. Note that blocks can be nested.[code]...
Is it possible to use regular expressions to parse the code and return the name of each block separately? So in the above example, it should return block1, block2 and block3 but NOT "block 2 contains" or "and another" (no nested blocks).
I am trying to replace the vb source code in our application by using a streamreader and a loop.
the reason for this is, we've upgraded to a later version of 3rd party grid controls and the properties of the controls changed, so we have to change the code 13 XXX times.[code]...
