View 8 RepliesI would like to generate a combination of words. For example if I had the following list:
{cat, dog, horse, ape, hen, mouse}
then the result would be n(n-1)/2
cat dog horse ape hen mouse
(cat dog) (dog horse) (horse ape) (ape hen) (hen mouse)
(cat dog horse) (dog horse ape) (horse ape hen) etc
There are these 19 bytes (I am looking for combinations not the number of combinations)
17 00 00 00 A4 EA DB 13 02 00 00 00 00 00 00 A3 D3 02 CC
I need any possible unique combination which matches these "rules":
at least 4 bytes long the order of the bytes can't change(so 17 A3 D3 02 CC is ok but A3 D3 02 CC 17 isn't, because in the original string 17 was at the being but A3 D3 02 CC was at the end)
Let me try giving you examples of possible combinations:
17 00 00 00 A4 EA DB 13 02 00 00 00 00 00 00 A3 D3 02
17 00 00 00 A4 EA DB 13 02 00 00 00 00 00 00 A3 D3
17 00 00 00 A4 EA DB 13 02 00 00 00 00 00 00 A3
[Code]....
See the bytes stay in the same order for example the first byte 17 can only in the first byte's place
I don't want combination like
A4 17 02 CC
Because now 17 has changed order compared to A4
I want it so that when someone clicks a button it generates a code in the format of XXXXX-XXXXX-XXXXX-XXXXX-XXXXX I want them to be letters and numbers combinations

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.
I have an array like so:
Dim classes() as String = {"FR%", "SO", "JR", "SR", "SR5"}
I need to loop through these values like so:
For Each value as String in classes
Next
Problem is, I have a If..Then..Else clause inside of this For Each..Next which says something to the effect of:
If actual_class = value Then
txt.Text = "Welcome"
Else
txt.Text = "Goodbye"
When I run this, unless the individual is the last value in the string array ("SR5") they are going to get the message "Goodbye"...so, I need somehow to both iterate through each value like is done with a For Each..Next loop but also break out of the loop once it hits the student's class, like a Do..While loop - so that their value doesn't get overrun by the Else clause.

I have a windows based application using vb.net 2005 . My application , i have an array. The array contains 5 numbers. The numbers are,
3, 7, 2, 8 ,1.
I want to get the best combination of sum is 10 by using code .How will i do?
Im having some trouble creating this, What im after is like a database, and im sure its got something to do with it, Ive looked all over, but nothing gives me exactly what i want, Basically what do I do when, I have 9 Options, Example, Blue Black Red Green etc...Up to 9 In 3 boxes, now what im after is a shorter way for me to put, example:

Then with not much code have it so it works with all 9 colours and gives an answer

I would like to be able to add every combination of a list of numbers to determine which combinations equal a specific result.
Simple Example:
List: 2, 4, 6
Result: 10
How many and which combinations of numbers result in the number 10? The correct anwser is only one which is 4 + 6 = 10. The example is simple but the actual list may contain as many as 10 - 15 decimal numbers.
I have thought of the following as a possible way of checking each combination by using binary:
- There are 3 total number so the possible combinations would be:
123 - Three numbers
000 - Add no numbers
001 - Add the last number
[Code].....
However, I don't know how to actually match up the bitwise bits to the numbers in the array to actually add. Example:
101 - I should check if 2 + 6 != 10 per the example above so this wouldn't satisfy the result... does this make sense? The answer would be 4 + 6 = 10.
how to check and add all combinations from a list of numbers to determine if the result is a specific number?
I'm looking for some function to put together every possible combination of letters and number to create a string that is 14 characters long. I have found ways to make every possible combination of letters and numbers seperately. However, I've never run across anything to come up with them together. Every string created must contain letters and numbers.I just have no idea where to start on this one.
View 9 Repliesi would like to know that is there any way to activate a button with the Ctl and a key combination
we can do it with Alt and the key combination but my client is asking for ctrl & the key combination i have searched a lot but failed to find anything.
secondly :
i have used the alt & key combination for my buttons but the prob. is unless and untill the user presses the alt key the key combination is not highlighted. i have seen progs. where the key that is used for e.g. i have given &Add then the 'A' key is highlighted always with the underline. but when i am doing it by giving the name as &Add unless and untill the user presses alt the underline under A doesnt appear. do i have do more than just giving "&Add".
