Combinations Of Multiset Numbers In 5 Column Textboxes (of Range 1-90)?
Jun 5, 2011I have 5 columns of 11 textboxes each on my form the textboxes are generated with this code
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'column 1 textboxes
[Code].....
i need a code to generate all the possible combination of the numbers a user types into the textboxes i have two images (Panel3: the textboxes where added during design time) image2: the textboex were added using the code i gave about
generate all the possible combinations of numbers typed into the textboxes (Example see panel3.jpg image),
The user will type in the desired unique numbers into the textboxes without repetition (Please see the image i did not repeat any number, so can the code detect when a number have been typed twice?) Else when running the program i will be carefull not typing two numbers twice, but its adviceable to detect when a number is typed more than once.
Then the amount of unique number the user will type or supply to the desired textboxes does not matter here and as you can see in the image the amount of numbers in each column is not the same ie it may or may not be same amount (but number must be unique. Please try and see if it can be done to prompt user to enter the amount of numbers to supply in each column)
Then After supplying the numbers just like the one in Image, The button Click will generate all the Possible Combinations of the all the numbers typed into the textboxes in the columns.. Then After generating the combinations in the Listbox, the next Button will be able to delete them from the Universal 90c5 just like the former.
Asp.net - .Net Iniatialising A Class Using System.Reflection And System.Type To Create A Session Based Singlton Extension Method
Jun 11, 2009I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

Input Data (in All Textboxes) Using Create Button?
Nov 16, 2011I am trying to save new data every time and then I have to edit it or load it. here is a screenshot you might get some idea by looking at this:
First I will input data (in all textboxes) using create button which will be stored then If I want to edit any thing I will input only the part number and press search. the stored data will come up. I will edit it and update it (Load button is update). Now I can save it in txt file and load it using regex but the problem is edit. I can not edit. If i create a database I cannot save 100 parts (or may be more) in one database so it might create too many db files. So is there any other option I can save parts detail then load it and edit it without create so many dbs?

View 2 RepliesCreate A Login For My Windows - Clicking Button Irrespective Of What Is Entered In Username And Password Textboxes
Aug 27, 2009I hv to create a login for my windows appn(this is the first tym i am creating a login in visual studio) i am unable to figure out exactly what should i do

Now i called this function on the button click of my login form and passed the values of username and password textboxes as parameters to it. But the problem arising is that it is logging in by simply clicking the button irrespective of what is entered in the username and password textboxes.
I think this is because ds.Tables.Count is never 0(whether the username and password match or not) Use code tags when posting your code. Code tags are used like so =>
