Combinations - phone number - C#

1 New Member
Hi,

Given a phone number I need to print out all the word representation combinations possible from that phone number. Digits translate into chars like the following:

1 = 1
2 = A B C
3 = D E F
4 = G H I
5 = J K L
6 = M N O
7 = P R S
8 = T U V
9 = W X Y
0 = 0


So the phone number 23 would result in:
AD
AE
AF
BD
BE
BF
CD
DE
CF

And If my phone number was 2665 I could pick the word representation "COOL", or "BOOL" etc.

Can anyone help?

Thanks!

Does anyone have any code for doing combinations in VB.net or visual basic ? I'd like to be able to get an array of combinations (not permutations) of words from a base group of words while specifying the number of unique words to be used in the result set. For instance if I have the set {cat dog fish snake} I'd like to be able to get back a result array of all possible combinations (not permutations) of X number of words from my base...

The below code dials a phone number using C:\Program Files\Windows NT\dialer.exe. The problem is that dialing rules are ignored. MS Knowledge Base Article 266253 suggests that entering the phone numbers in canonical format, e.g. +011 (408) 2578652, will fix the problem -- but I tried and it didn't work. I'm wondering if anyone can recommend an alternate phone dialer -- preferable one that does not use a GUI like dialer.exe, which...

I've been trying to find an algorithm that will output all of the possible combinations of items in an array.

I hope this is the correct newsgroup for this query (if not please give me a pointer to where is best): I understand the theory of normalisation etc and am trying to follow best practices in the design of the database for a new project, but I am unsure as to the best practice when one wants to store data relating to combinations of arbitrary numbers of sets of data. For example, take the following two groups of sets, each containing...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
