VS 2010 Button To Increase Variables

Dec 27, 2010

Still working on that overlay. I am stumped on what I think is my last function. I have a + and a - button that needs to control a text box that has numbers in it. For instance: TextBox1 shows the number 2 in it. When I click the + button I want it to increase that number by 1. It sounds too simple when I say this out loud, but I think I am stumped with this basic function. I don't know where to begin.

Code An 'increase' Button To Prompt A User To Input A Rate By Which To Increase Select Prices In An Array?

Feb 16, 2009

I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.

'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}
Dim rateIncrease As Decimal
Dim isConverted As Boolean

Increase The Function Of The Submit Button?

Oct 25, 2011

I have a webform currently works like a charm. It posts the info entered directly into my database with out issue.

I need to add a step in there where when the submit for is pressed an email will be sent to one of 2 different emails addresses.

The snippets below are the 2 statements I think I need to have in the code, I just haven't been able to figure out how to complete them.

'If (cmbIPTypeBiz.SelectedValue = "Static" And cmbNumIPBiz.SelectedValue = "CIDR/30") ****Then send to email1.com****
'End If

[Code]....

The items in the starred out section are where I am struggling.

So, to sum up, I need to be able to make this form shoot off an email to one of two email addresses based on whether or not a specific field has CIDR/30 in it.

VS 2010 Add Tips To Variables In Sub?

Oct 26, 2009

Is it possible to add the tips to your code in the sub so the user know what part of the sub is for? Like if I create a sub like this:

Private Sub Stuff(ByVal Tip as String)
End Sub
When the yellow box comes up you might see something like:

Quote:

Private Sub Stuff(Byval Tip as string)

This is just some text you use in the sub, don't worry about it.

VS 2010 Copying Db Fields To Variables?

Apr 5, 2011

I have been using VB a fair bit in the past developing a Access Database, recently I wanted to give my front end interface a bit more power so I have started learning VS 2010.

Anyways, I am still using Access for my databases and i am having a bit of trouble working with the data in VS 2010, what i would like is the following:

A way to form a string or integer from a SQL query (from a single field or multiple on that row) assuming the query will always return one row.

Then a way to write string or integer variables back in to db fields.

example:

Dim cn As New OleDb.OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|ItemRegisterDB.mdb")
Dim cmd As New OleDb.OleDbCommand With {.Connection = cn, .CommandText = "select * from tblItemregister where ItemID = 1"}

[Code]....

Example = ??? 'What would i need here to copy fields from that row to string?

VS 2010 Public Variables For All Classes?

Mar 30, 2011

I have a MDI application and a very complicated class there which populates its properties from a dataset derived from an external database. Each form, including child forms have to be able to access that class and use its properties thorughout the whole session.I don't know where to 'preserve' these property values within the application. I kmow many books etc. suggest not to use public variables but I really can't find a way to solve this other than to use a public variable (which is a list(of my custom class) in this case.
I have a separate class called PublicItems.vb and declared there my public variable as

Public Shared secuniverse As List(Of myCustomClass)Is there something wrong with the syntax because if I try to use the variable secuniverse in my main application class, I get the following exception:'sectoruniverse' is not declared. It may be inaccessible due to its protection level.

VS 2010 Shared Variables And Threading Pin?

Mar 12, 2012

So I am currently attempting to wrap my head around create multi-threaded programs and I am currently running into an issue when using a Shared variable across multiple threads.The program is structured as follows: Public Shared IsActive as Boolean

Main Thread = GUISets the Value of IsActive through a Button ControlTwo Worker ThreadsBoth threads are while loops that read the IsActive Boolean Ex:While IsActive = True Do Work End WhileHowever when I change the value of IsActive from the Main Thread it causes the worker threads to stop (ThreadState = 16).

I have been reading that I have to synchronize/lock shared resources and have tried SyncLock and Monitor methods without success (it is entirely possible I am not using the above correctly, so If someone could provide proper examples for the above situation using the mentioned methods please share them).

VS 2010 Working With Boolean Variables?

Jun 16, 2011

I am working with a multi form project. The long and short of it is that when i originally load form 1 ... all bool variables are false. Once i load form 2 and perform my operations some of my bool variables will be set to true.

I need to have some sort of object to listen for those changes. What i have come up with so far is the following. Private Sub patient_frm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

[Code]...

The if statement will work but i need a way to make it keep looking for changes in the boolean variables.

VS 2010 Class / Properties And Variables W/ MySQL

May 3, 2012

Ok so my boss told me that I can't use DataSet's and dataadapter and such like this because it isnt good for scalability. So, I must change the way I have my 28,000 records binded to my form. The problem is, I'm only 3 months in with VB.NET and I don't know of any other way to accomplish what I need to do. I was reading somewhere that I can use a Class as my "Order" and I can bind the variables/properties to the form and with this, I can navigate through records while having controls on each important part of the "Order". Unfortunately, I don't know what I'm doing, this is as far as [code]Any guidance as to what I am to do from here in order to pull the data from my database and bind to the property, then to a text box/combo box, and a way that I can use my binding navigator to go through the many records.
