I would like to have some sort of percentage on the amount of times each button has been pressede.gButton 1 is pressed 5 times, button 2 is pressed 3 times, button 3 is pressed 2 times.I would like this to create a percentage output onto the same form that is updated everytime a button is pressed on the form.
View 5 RepliesI am attempting to draw and fill a rectangle using percentages passed through the text properties of 4 textboxes. I am attempting to do this in VB 2008. For example:
textbox1, 15%, green
textbox2, 35%, blue
textbox3, 40%, red
textbox4, 10%, orange
I'm trying to create a game that involves rolling a dice. When I load the program and click the btnRoll button, the dice works fine and stops after a random number (between 10 and 20) of face changes. It then records the score in the a new line in a ListBox. Only problem is, when I press the roll button again, the face only changes once before recording the result.
I have tried creating a separate program that simply rolls the dice without recording the result, and it works fine. So I used roughly the same code in my game, but it still won't work. I have tried looking online for help for a few days now, so I figured this would be a good time to ask here.[code]...
I'm calling a third party stored procedure in Oracle from VB that is not rolling back.
Code first (I'm simplifying):
Connection string:
String sqlstr = "SERVER=x.x.x.x;Database=db;uid=sa;pwd=admin;Connect Timeout=60; Min Pool Size=5; Max Pool Size=100;";
The call (I've just forced a rollback immediately after the execute to test it):
Dim Oraclecon As New OracleConnection(_OracleConnection)
Dim sqlCon As New SqlConnection(_SQLConnection)
Dim oTrans As OracleTransaction = Nothing
[Code.....
I can't give the details of the stored procedure but it does a commit and rollback inside it.
Either way, it is doing an insert, and that immediate rollback does not rollback the insert.
However in my opinion they require a lot of prior knowledge on how to programatically refer to each item.
Does anyone have a link to or can create a relatively basic example of how to achive a running total in the footer for an ASP:Gridview?
I'm trying to calculate the rolling average in a crystal report. I have got 4 weeks in a month, and I have calculated the average for each week so long. Now I want to calculate a rolling average. eg:
For week1: rolling average = (week1Average)/1
For week2: rolling average = (week1Average + week2Average)/2
For week3: rolling average = (week1Average + week2Average + week3Average)/3
etc.
The problem with the code below is that, it is not looping through,therefore the rolling average for each week is the same as its average value wich is not correct.
Dim i, weekNum as number
Dim tot as double
weekNum =Distinctcount({ItemRating.WeekNo})

I have one multi-row INSERT statement (300 or so sets of values) that I would like to commit to the MySQL database in an all-or-nothing fashion. insert into table VALUES
(1, 2, 3),
(4, 5, 6),
(7, 8, 9);
In some cases, a set of values in the command will not meet the criteria of the table (duplicate key, for example). When that happens I do not want any of the previous sets added to the database. I've implemented this with the following code, however, my rollback command doesn't appear to be making a difference. I've used this documentation: http://dev.mysql.com/doc/refman/5.0/es/connector-net-examples-mysqltransaction.html
Dim transaction As MySqlTransaction = sqlConnection.BeginTransaction()
sqlCommand = New MySqlCommand(insertStr, sqlConnection, transaction)
Try

I get the DUPLICATE KEY exception thrown, no Rollback Exception thrown, and every set of values up to duplicate key committed to the database.

I have a certain problem with 2 number generators that I have. My problem is that I want them to act individually. To where they seperatly come up with a random number. Mine is from 1-6 for 2 random number to simulate the rolling of two 6 sided dice. The problem that I have is that when I run the program they always generate the same number no matter what that number is. When I step through it step by step while the program is running in the debug screen they come up with a different number. This is in visual basic 2010 express edition.

I'm doing some maintenance on some software originally built by my predecessor at the company (who has since moved on to greener pastures). I'm currently rolling out a new version of the software. At this company, the installation procedure is basically to just shove the /bin/Release directory out into our automated program updater's magic directory, allowing it to automatically copy the contents of that directory over to the local /Program Files/ and let the magic happen. The magic always seems to happen, so there's no big issue, there, although it does weird me out somewhat, after many years of .msi installers...

Coming form too many years of VB6 I have a natural inclination to write my own data access code, etc. rather than using database wizard, etc. Same goes for using simple databinding to recordset rather than managing object collections and tying those to controls
I am finally moving to VB.NET and find myself on a solo project without any team on which to lean, so I have a couple related questions as I try to get my head around the transition. The project is basically a line of business app with a SQL Server back end.
1. Are the data designers/wizards so good now that rolling your own is no longer worth while?
2. Is the data-binding now fast, flexible, and reliable?
3. Can you recommend a good book or robust on-line tutorial that covers this sort of programming? 2008 or 2010 preferred.
So my question is, I'm wiriting a VERY basic dice rolling program for my computer programming class in high school. I'm using a randomize function to generate numbers but I only want it to do numbers 1 - 6....how do I do this?
Dim x As Integer
Randomize()
x = CInt(10 * Rnd())
Dim Y As Integer
Randomize()
Y = CInt(10 * Rnd())
That is my code for my x and y (each die) to generate code, but how do I make it do 1 - 6 ONLY? Develope a game that in which a player rolls two dice. Each die has 6 faces. Each face contains 1, 2,3,4,5,6 after the dice have come to rest the sum of the spots is calculated, if the sum is 7 or 12 on the first throw, the player wins. If the sum is 2,3, or 11 on the first throw, the player loses, and the house wins. If the sum is 4,5,6,8,9,10 on the first throw the sum becomes the player's point. To win, a player must roll the dice until the plater rolls the point value. The player loses by rolling a 7 before rolling the point. I also have another question, How would I set this up to keep up with points and stuff? and the part that says "The player loses by rolling a 7 before rolling the point." I have no clue what to do on that. I'm not asking for code hand outs. I'm just asking what functions and such I'd use to write the code.
I'm using an Entity Framework context, and sometimes would like to create a transaction so that the client can do multiple changes and then commit/rollback them all together.However, if many changes were made, and SaveChanges() was called multiple times, after which a rollback is called, entities that were commited already, will remain the way they were commited, and would not roll back.Here's how my transaction-relative functions look like:
Public Sub BeginTransaction()
Dim context = HttpContext.Current.GetObjectContext()
If Not context.Connection.State = ConnectionState.Open Then
context.Connection.Open()
End If
[Code]...
Not only does the test fail, but it also leave the ObjectContext in an unstable mode, because it still has invalid changes in it.
I am trying to get a percentage that just does not seem to work.I am using WMI to get the Total Physical memory of my system and then the Free Physical Memory. Then get the percentage.
2147483648 - Total Memory
838028 - Free memory
According to Task Manager my physical memory is 59%. This is the code I am using but I can not get 59% or 41% that is free.
temp = FM/TM
temp = temp * 100
percent = FM * temp
How can I round a percentage off to the nearest whole number? [code]
View 5 RepliesIs there a better way to parse percentage to double like this?

I have a program that is calculating the cost of a certain number of plane tickets, the validation and basic calculations are fine the only problem i've got this: There is a discount text box field called "txtDiscount" where IF a user enters a number it will discount this as a percentage off the total cost of all the tickets, but I cannot get it to work [Code]
View 2 RepliesI have a fixed percentage 0.3% I need to multiply this by a number of months which varies 1 to 12
Having done this I need to add the percentage to a pre-determined number
so as an example
£300 + (0.3 * 10)
I can get the 3% (0.3 * 10)
But when I add this to the existing number (£300) it equals £303 not £309 which is what it should equal.
Can anyone advise the way of adding a percentage as appose to just another number? This also need to allow for -percentages i.e. -3%
The equation I am using is below and I appreciate there is nothing to set decTotalPercentage as an actual percentage but that's because I am stumped...
decTotalPercentage = decPercentage * intMonths
decFinalPercentage = decMoney + decTotalPercentage
I have a problem regarding an access file I attached to this post.I have a table which contains the costs(VVGK) for each month in 2008, 2009 and 2010. For each month we have planned costs(Plan) and the real costs (Ist). And what I want to realize is that in the report in the top right it automatically displays the percentage difference between the plan and real costs of the last month. And this should then be automatic every time I give new input(new month, new VVGK Ist).
View 2 RepliesI'm developing a data logging application using VB for the actual logging to a MySQL database. I'm reading a value from a device and then running an insert query every minute. This is great but if the value doesnt change all day then my records are going to all be the same. I'd like to try and calculate the percentage of change on the value and only run the insert query if the percentage of change is greater than, say 5%.

Im trying to get a sales percentage program to work and im having trouble on the last part. My homework is to get the original price from the customer and then take the sales percentage off and show how much it is. Then after the first percentage is off take an additional percentage off part and then show the grand total. I got all the way up to the additional percentage off part to work right.

How can i round it off to just whole numbers e.g. 13%?
what I need is the following:
1)A way to add a percentage to a ProggressBar.
2)A way to send by email the text that contains a TextBox.
3)A way to call the text of a TextBox in a MessageBox.Show.
4)A way to save what is written in a TextBox, just before it is closed.
5)A way to allow only numbers in a TextBox.
I was just thinking is there a method i can use. For example if the maximum value is 200 and the current value is 97. or i have to use math to get the percentage.
