Implement A Controlling Design Logic That Prompts The User For A Length And The Area To Calculate?

Aug 12, 2009

I am trying to implement a controlling design logic that prompts the user for a length and the area to calculate until he or she enters a number less than zero in the length to end.So far I have it where I believe it�s doing the calculations but it�s not ending when I input a number less than zero or zero.

Sub Main()
' Declare Length As Float
Dim Length As Double
' Declare s, c, t As Float

VS 2005 How To Implement Some IF/Then Logic

Mar 17, 2009

I'm sure this should be easy but I'm having trouble getting my head around it. I shall try to explain what I need as best I can.I have a string called SoftwareGroupName. If that string is empty, I need to run some code that logs a call in our Helpdesk. So far, so simple.I then check two other variables, AuthorityLevel and InstallType. If the AuthorityLevel is anything other than "OnRequest" then a call is logged in the Helpdesk System. Again, so far, so simple.

The problem occurs when the AuthorityLevel is "OnRequest". At this point, the application should again log a call in the Helpdesk Call with a status of "Resolved" as well as add the user to the relevant group in Active Directory.What I need to be able to do is, effectively, say "If the AuthorityLevel is OnRequest and SoftwareGroupName is not empty then go ahead and create the call and update the group. However, if softwaregroupname is empty then DON'T even try and update the group and create a call with a different status (e.g. Assigned).Here's what I'm doing so far. But it seems wrong to have to check that SoftwareGroupName is empty twice.

C# - Implement A Logic For Monitoring The New Files In The Folder?

Jan 26, 2012

I am going to be creating an application which will monitor a folder, which could be a network folder and when new files are added in that folder it will notify the application. On notification application will import those files names into a listbox and will give the option to user to organize(move) those files into a different directory.

1. I have to implement a logic for monitoring the new files in the folder.

2. I have to move it into new directory and in some cases I will have to create those new directories as user specify.

For the first step I am confused to either implement it as a windows service using FileSystemWatcher class, example can be seen here. [URL] or do a file check based on timer, lets say every 5 minutes. If I do it as a service how can the service notify application?

Avoiding Microsoft Excel Prompt - User Is Getting Two Prompts

Feb 7, 2012

I'm writing the following bits of code for a SaveFile Dialog box in Visual Basic 2010.NET. The code works well as the XLSX file is created and opens in Microsoft Excel. However, the problem that I am having is that if the program overwrites a file, the user is getting two prompts. One prompt is from the program's own SaveFile dialog confirming the choice. The other is from Microsoft Excel asking you the same. It's as if the program is running in the background. Does anyone know how I can write this code to save the file as an Excel file? [Code]

Create An Application That Prompts The User To Enter Today's Sales For Five Stores?

Feb 18, 2009

I have to create an application that prompts the user to enter today's sales for five stores. The program should then display a simple bar graph comparing each store's sales. Create each bar in the bar graph by displaying a row of asterisks (*) in a list box. Each asterisk in a bar represents $100 in sales. I have to make two different versions of this program. One using a "do while ... loop" and the other using a "for ... next loop". Could someone give me a hint on how to do this. I the "do while ... loop" version and I have had some problems, especially with converting the numbers to asterisks.

ComboBox - How To Resize Dropdown Area Based On Item Length

Jun 11, 2011

Since we have to resize the combo box dropdown area based on the combo box item length, used the drawstring() to add items to combo based on the item length. This gave us the below issue: On moving the cursor on the drop down area the font color and the background color are back hence the text is not readable (i.e. the whole item becomes black).

Below piece of code is used to achieve this,
Private Sub cboClient_DrawItem(ByVal
sender As
Object,
ByVal e
As System.Windows.Forms.DrawItemEventArgs)
[Code] .....

We tried changing font color and the dropdown area backcolor on selecting a particular item. How to make the text readable (i.e. the font color should change while if we scroll on the item).

Forms :: Implement A Classic Layout Design In .net (2.0)?

Nov 14, 2010

how to implement a classic layout design in vb.net (2.0).The application design is the classical toolbar panel at the top and different panels stacked at the bottom. Depending on the button pressed at the top in the toolbar panel a different panel at the bottom will be available.This is thought to have different part of the software available on different panel but with the toolbar panel always available at the top.To implement this I thought:

1) one tablelayout with 2 rows. First row contain a panel with the button (toolbar panel) and adding/removing hte correct panel requested on the bottom row.

Design Patterns - Implement The IDisposable Interface With A Dispose?

Apr 21, 2009

Recently I needed to compare a suggested pattern for IDisposable and object finalization with the auto-generated one we which VS2005/VB.NET provide. We have used the auto-generated one a fair bit, but after looking it the two side by side I had a number of questions about the VB.NET implementation..

[Code]...

Overall I am confused by the supposed added value of having an extended code-path that executes when Dispose() is called explicitly(as opposed to having a common path that is executed regardless of whether or not Dispose() was called explicitly). how it does anything other than delay the actual release of managed resources if Dispose() isn't called directly. In essence it seems to only work to make the managed resources unreachable in the object graph, orphaning them until the 2nd GC run rather than freeing them at a point where they are known to be no longer needed.

Reloading User Entered Data At First Run Logic

Aug 20, 2011

Ok so I have designed a program to figure out commissions for phone sales at my company. Since the devices we sell and their associated prices change over time, I had to make that data within my program dynamic. I have a form within my program (frmprice) that has 160 textboxes - 80 for the devices and 80 for the associated prices. Now I hard coded the .text members with default values for our current stock of phones and prices.

I also added code so whenever that form with the phones and prices (frmprice) closes it saves any changes that have been made to either the phones or prices and when the form loads it overwrites the default data with any data that the user had entered at last run.

HERE is my logic problem. At the very first run the program is overwriting the default hard coded values with "" because no user data has ever been entered before. So when the form with the prices loads, it passes the user entered data from last run which is null because it has never run before. If I test to see if default value <> the user entered data before it executes the code to pass the user entered values it will always test to be true because the user entered data is null at first run. If I test to see if the default value is = to the user data it will always at first run test to be false because there is no user data yet.

HOWEVER once the user entered data is initialized (anytime after the first run) I need the program to pass the user data from the previous runs back in. Just NOT at the first run. Here is the code i am using: (in the code below the variables ending in "val" are the ones that are of the type string and are saved in the application settings) The frmprice_Load Event:

Time Logic - Retrieving Specific Times From A User Form

Oct 10, 2011

I need some help working out the logic when retrieving specific times from a userform I have created. In my userform, users are required to input a start and a end time in 24 hour time format. I am struggling to work out how best to analyze the selected times in order to multiply them by a set of rates, the rates are quite simple:

DayHours rate (day time is between 07:00 - 22:59)

NightHours rate (night time is between 23:00 - 06:59)

I cannot workout the logic to ascertain how many hours have been selected for which rate in an elegant manner, my best attempts so far are clunky and not quite there.
