Following is the format of the data stored in my arraylist.
A-Amsterdam
B- Brussels
C-Canada
so and so forth. I wan to search my array list by passing just the first few characters till '-' So if i have something like AA-Test then i want to pass just 'AA' to check if it exists or not.
I know that i can use contains or binarysearch but it does not serve my purpose as they both compare objects.
I previously posted a Question about code that uses a function to return the frequency of characters in an array. I have now got this code.
View 5 RepliesI'm having difficulty passing a variables in a an array list. [Code] I have to pass the paramvals array to the function. The paramvals array contains the string but not the value of variable of that name. For example, parmaval(0) should contain the value of vSequence but it showing me that it contains string "vsequence".
View 3 RepliesHow do I Extract all Characters in Unicode, UFT8,iso-8859-1 to 9 etc to a list or array In VB?I have a SQL Database of which contains values from 51 languages. I need to detect which ISO-8859-? Was used to encode the string value. For example Turkish Characters i.e. "Ö Ş ş ğ ü Ç" Once I have the correct ISO, I need to convert the Chars with-in the string to Unicode using only if the string value contains values that are not UFT7, and convert the string to HEX?The reason I need to detect the ISO etc is because we are sending SMS, of which jump from 160 characters to 70 if a special characters are used, i.e. "Ö Ş ş ğ ü Ç" Is there a simple way to extract the ISO-8859 Character Set to a Array etc, or is there a simple way to check if the character exists with a ISO-8859 data set?

View 11 RepliesI am trying to search the 4 columns of my array by using this click event. The column is determined by a radio button as you can see. I changed my code from last time and now it works, but only for the first column. If i try to search out a string in the second or third columns I get an error based on the line highlighted in blue HTML accutally shows and it is green. the error says Index was outside bounds of array
Like i said It works fine for all values in the first column, accually the second (Numbered 1). If i enter a value in the partsnumBox and it is found in the the 2nd 3rd and 4th columns I want the value in the first column (0) of the same row.

I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?

value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.

I have to search within an array and display the number of occurrences that a value within the array appears. I know that my code is incorrect but this is what I have so far. If anyone can point out what I am doing wrong that would be great.

SELECT ContactID, FirstName, LastName, Male, Female, Email, Address
FROM Contact
WHERE (FirstName LIKE @FirstName + '%')
The above query works and returns values on first names that begin with whatever item I type in a text box.
How can I modify that code to search for items containing specified characters instead of just searching for items that begin with the specified characters. I would still need to use a wildcard because it is a search field. see below for an example
For example can I query the FirstName column to display people who's name contain the letters "an" in that order a before n but anywhere within the word e.g.
- Anna
- Jane
- Samantha

I am trying to pass a 2D array into a dll I wrote in C. When I run the program, it crashes at the first line (in the dll) that I try to read the array. It gives an error that it is trying to read protected memory. I'm guessing this means the array was not correctly passed to the dll, so the program is trying to read a memory location that doesn't exist. Is the problem somewhere in my VB code? If not, it must be in my C code, right?
Here is my VB code:
Declaration of the function in the dll:
Code:
Private Declare Function image_processing Lib "image_processingDLL.dll" _
(ByRef image_array As Long, ByVal dpi As Long, _
ByVal xDim As Long, ByVal yDim As Long) As result
Calling the function:
Code:
Call image_processing(hImgArray(0, 0), hImage.HorizontalResolution, _
hFilmPictureBox.Width, hFilmPictureBox.Height)
I am using Visual Basic .NET 2005 and I need to call a DLL made in VB6. Couple of days ago i wrote a test dll in VB6 and called it from VB.NET. I passed an array and another variable. And the dll got it and displayed the values in the array. (I didnt save that code)Now when I am writing it again I am getting an error "Specified array was not of the expected type." [code]If I do not pass array then it accepts but otherwise it does not. The array here is CD().
View 2 RepliesI have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
I m a student and new to VBI m triyng to pass an array as parrametersAnd the compiler says I havent declared the array my coding is as below

Console.Write("Enter First Name " & lLoop & ": ")
[code].....
When I try to do the same in .net the "array argument" value of the second sub is either Nothing or I get an error saying "Value of type 'String' cannot be converted to'System.Array'."I've tried converting the array to a system.array but it will not hold all the Types of data it needs to hold. (I tried 3 days ago and don't remember what Types would cause an error. My 1st value is a string and the second is an integer and this caused some error.)

Button1 click event
Dim array1 (3,3) as string
array1 (3,3) = "BLA"
End Event
Now, in the same class, I have another button.
When I click on this button2, i want to use this array to stream files to textfile.
The problem is that I cannot pass data from button1 click event to button2, as I have to declare the array again, and that causes array to lose data on button2 click.
If I however, declare array on top of class, I get a funny error sying out of index range etc.
