Replacing A String With Index Of An Array?

Jul 12, 2010

i have an array that contains a-z.When i enter text like "ab" into a textbox and click the button, it will search the array and replace the text accordingly to the index number of the array and rewrite into the textbox with the index number.

But what i got from the code below is "ab0 1".May i know how to do so that the textbox will only display the index number and not with the letters. Also, how do i search the array from index 12 onwards to the end of the array.

For Each b As String In TextBox2.Text
If abc.Contains(b) Then
Dim ab As Integer = Array.IndexOf(abc, b)

Dynamically Create Array Based On String Length Property and Index Of Method

May 4, 2009

I would like to format output to a property of a custom control I have made.For instance I have a literal control in my control and when populated I want to check if it is longer than 30 characters long, if so, then go to the next space (as to not cut the word off) after the 30th character and place a <br /> tag in to place the next 30 characters on the next line.So if there were 100 characters in a string, there would be 3 line breaks in the label.I have the looping worked out to get the label populated but cannot get how to dymaically create the array based on the string lenth property and index of method.

Array.Sort(array) - Specify A Numeral Sort Based On The First Character In The String?

Jan 29, 2009

Sub Sort()
ReDim RollsCC(NumOfPlayers - 1)
For N As Integer = 0 To (NumOfPlayers - 1)[code]....

Here I am creating a temp single dimensional array, merging my 2d array into it, and then attempting to sort it by Rolls(N,1), which is a integer 1-6, Everything seems to be working right with the exception of this.

RollsCC.Sort(RollsCC, 0, 1)

How would one specify a numeral sort based on the first character in the string? im aware that I am switching Rolls(n,1) and Rolls(n,0) information during the sort.

Search For A String In An Array And Get Its Index?

Nov 6, 2010

Given an enum similar to this:

Friend Enum TestValue As Int32
tstNotSet = -1
tstA = 0

[code]....

As noted in my comment to Jon Skeet, this construct, along with the rest of the Object's components, executes 100,000 times in a profiling loop in ~570ms (rough average of 3-5 runs).

Exchanging the above construct out with a smaller Array.IndexOf construct loops 100,000 times in ~630ms (again, 3-5 runs, rough average, the whole Object). The new construct looks like this:

Dim p As Int32
p = Array.IndexOf(TestValues, s)
If p <> tstNotSet Then

Search An Array Of Structs Using A String As An Index?

Apr 1, 2009

I have been searching for a while now, but I still can't seem to figure this out. I wrote a rather large program, and to make things more efficient I started to create structs to store more info in a variable.All was well replacing my old code with new code, till I reached a certain point and found that blindly using a loop of integers to access the indexes of the array wouldn't work anymore... I need to access a specific struct by the information contained in a single variable within the struct (like a hashtable key), but can't seem to figure out how.

Is it possible for me to go through my array indexes in a fashion like this?:
Dim myArray(TableCount) As myStruct
Dim TableName As String = "SomeTable"

[code].....

Get Index Location Of A Piece Of Data In An Array

Sep 15, 2011

I am trying to import a text file into a data table using VB.NET. I need to loop thru each line of the text file and put certain elements of that line in a new row of the data table. The line may contain 50 elements, but I only need to get 15 of them. The very first line is a header row, which contains "File Name", "Object Name", "Object Weight", etc. The trick is the element locations move from file to file. For example, "File Name" element may be located at 0 in one file and then 15 in the next file. I need to find the exact location of my desired elements and save them to a variable. Then use that variable to locate the exact piece of data in the text file line to place in my new row.

The code below obviously doesn't work, but it kind of illustrates what I need to have done.

Try
With dt
.Columns.Add("fltObjectWeight", Type.GetType("System.Double"))
.Columns.Add("vchObjectName", Type.GetType("System.String"))

Comparing Field Values Based On Array Data In Access 07?

Aug 11, 2009

I have a query in Access 07 that identifies the following fields: ContractID, status, start date and end date. For each contract, I've been able to search a network share and upload its corresponding file; however I need to skip the import and write a record to a table for contracts with the same start and end date. I've included a placeholder (in bold below), but how do I make the date comparison work? Do I need to create a multi-dimensional array for that or can it be done with the code I have?

Private Sub cmdRefreshList_Click()
DoCmd.SetWarnings False

Replacing Repeating Numbers In An Array?

Nov 11, 2009

I have an array that hold 6 random number, then this numbers are sorted from smallest to highest. My question is: How would I go about replacing any repeating numbers with a different random number. I.e. 1 3 7 2 2 9 is sorted into 1 2 2 3 7 9, but I would like to see one of the 2's replaces with a different number (that it is not currently in the array).

I have no code for this part - but the code for making the random number, storing them and sorting them works fine.

Comparing Array Index To Combo Box Index?

I used a array for the movie quotes and a comboBox for the movie names. I have coded a portion of the program but I am stuck on how to compare the array quote being shown to what movie the user selects from the comboBox. I have tried numerous different things but none seem to work right. The way I have it coded now it shows that every movie I pick that it is right even if it is wrong. I am going to show part of the code here and also attach the entire solution for anyone that needs it .

Encoding Array.String > Array VB2005

May 27, 2009

I've been working with a sig capture application sample on a windows mobile device, The data is sent via IP to a host as a byte array and is then drawn onto the screen of the host as it appeared on the client. I was able to get this into the form of a bitmap object so I could print it or save to a jpg file. That all works well. The problem now is that I need to store this data in a database and then be able to recall it at a later time and recreate the signature image.

The byte array data is much smaller than the actual image so I would like to store it in that form. My issue is that when I convert this byte array into a string and back again my program can no longer re-create the image. Once I saw the problem I created the code below as a test and added the msgboxes to get an idea what was happened to my data.

C# - Conversion From VB6 String Data To .NET Byte Array

May 7, 2009

I'm writing a C# application that reads data from an SQL database generated by VB6 code. The data is an array of Singles. I'm trying to convert them to a float[]

Below is the VB6 code that wrote the data in the database (cannot change this code):

Set fso = New FileSystemObject
strFilePath = "c: emp emp.tmp"
' Output the data to a temporary file

The problem here is the VB6 binary to string conversion. The VB6 string char is 2 bytes wide and I don't know how to transform this back to a binary format I can handle.

Below is a dump of the temp file that the VB6 code generates:

And here is the dump of the data as I read it from the database in (=the VB6 string):
