I'm currently converting a Visual Basic application to Ruby because we're moving it to the web. However when converting some algorithms I've run into a problem concerning bit shifting.How I understand it, the problem lies in the size mask VB enforces on Integer types (as explained Here). Ruby, in practice, doesn't differentiate in these types.

I am writing a programme for Payment calculations.I have four textboxes txtPaymentDue, txtDiscount, txtBalancePaymentDue, txtAmountPaid, txtChange
PaymentDue, BalancePaymentDue and Change are calculated by the programme.My requirements are:
1) when i enter Discount in txtDiscount on EnterKeyPress cursor should go to txtBalancePaymentDue wherein it will display the calculated BalancePaymentDue and on next EnterKeyPress the cursor should go to the txtAmountPaid and finally on EnterKeyPress the cursor should move to txtChange.
2) When I enter a digit in txtDiscount it should take it as right to left sequence and it should allow the insersion of digits .......like if i want to type 36.45 then if i type 5 the texbox should immediately look like this 00.05 when i type next digit it should look like this 00.45 likewise when i type next digit it should display 06.45 and finally 36.45.
The problem is that, when you delete MM value from the MaskedTextBox, it is shifting remaining dd/yyyy values to left in the place of deleted MM.So we would like to know how to stop shifting of dd/yyyy to left when some data is deleted from the control.
View 4 RepliesCan anyone demonstrate with an example how to shift the position of a datacolumn in a specific position after it is added at the end of a datatable.For example lets say I have a datatable with 9 columns and 5 rows. Now I added a 10th column. However I need this new column as the 5th column which requires shifting. How do I perform this shifting?
View 3 RepliesThis is the general goal I am trying to achieve:My VB.NET program will generate some Lists that may contain booleans, integers, strings, or more lists. I want the program to output a "file" which basically contains such data. It is important that the file cannot be read by humans Okay actually, fine, human-readable data wouldn't be bad.Afterward, I want my Ruby program to take such file and read the contents. The Lists become arrays, and integers, booleans and strings are read alright with Ruby. I just want to be able to read the file, I might not need to write it using Ruby.
View 2 RepliesI would like you all to give me some links about embeding scripting languages and I would like to ask if it is possible to embed Ruby into a Vb.net application. I only know Vb.net c# and ruby and would prefer not to have to learn c/c++ (even though i probably will have to in the very far future).

View 1 RepliesHow would I create a list of elements in VB.NET, save it to a .dat file, and make Ruby re-create such list (as an array) with such elements (they will be strings, booleans and integers)?

View 3 RepliesFor some background please see the following thread where I just posted a solution that worked for me:[URL]..The issue involves the shifting of controls on a form when it is first being loaded (it may not necessarily happen in the Load event though). As I write in the first linked thread above.I have noticed it on a few projects -- all MDI -- but with no apparent rhyme or reason as to which controls get "afflicted". I've had it happen on labels, textboxes, pictureboxes, radio buttons, etc. Also the distance they shift is varied, as well as teh direction the move - sometimes different directions on the same form.There are no consistent properties that these controls share and I am positive that it is not a simple anchor issue. This is a true and serious bug and amazingly frustrating because there appeas to be nothing you can do or test to hack into the behavior and begin to debug it. Scrapping a solution and redoing it from scratch can seem like a viable answer it is this vexing.
My solution was to set the AutoScaleMode to None and the issue resolved itself immediately. Since many people come to this forum with Forms questions I thought it might be useful information -- at the very least it might get on the radar of some of teh answerers here in case a question pops up of this nature in the future.
I upgraded from async_sinatra 0.5.0 to 1.0 because the latter fixed this problem So far so good. But when I went back to my original app, (as opposed to my test app), which contained authentication, it stopped working. I am using vb.net to make a webrequest, and this worked fine under 0.5.0, but now fails with "The remote server returned an error: (401) Unauthorized."
