I am working with a bowling scores program that displays a high score, a low score, and an average. I need to know what flag to use to end the loop. If I use a number, that messes up the values I need.
View 12 Replieswith a college assignment. We are to make a program for a school class. It is on Flags of Europe. A Picture Viewer should show a flag and the students must type what the flag is in a text box. If it is correct it must say so in a label and display the next flag. I want it to add the correct answers the student got out of 10 flags.

View 3 RepliesI'm taking a course in Visual Basic 2010 and I'm trying to get a grasp on this new term called a flag. I kind of understand that it has something to do with a boolean condition. I don't quite understand what a flag is. I see references to it using the term flag. I understand it has something to do when a boolean, a condition triggers a flag. But what is the flag.
View 3 RepliesI'm using LuaInterface for .NET to create Windows Forms objects. This works pretty good except for one thing:I want to use the Anchor property of Control to make them resize automatically. If I only set one of the Anchors (e.g. only AnchorStyles.Top), it works, but this doesn't really make sense. I have to set more than one Anchor, which is done by combining them with "bit-wise or" (or by just adding them numerically).
In VB.Net both works:
Dim myLabel As New Label()
myLabel.Anchor = AnchorStyles.Top[code]....
which is in a sense correct as "LuaInterface treats enumeration values as fields of the corresponding enumeration typ" (says LuaInterface: Scripting the .NET CLR with Lua).It is also not possible to assign the value as a number:
myLabel.Anchor = 15 -- 15 = 8 + 4 + 2 + 1 = Top+Left+Right+Bottom
This time, the error message is rather unspecific:
LuaInterface.LuaException: function
Is there a possibility to typecast the number to the correct enumeration type in Lua?

View 18 RepliesI'm trying to use lambdas in some VB.Net code, essentially I'm trying to set a flag when databound is called.
Simplified it looks like this:
Dim dropdownlist As New DropDownList()
dropdownlist.DataSource = New String() {"one", "two"}
Dim databoundCalled As Boolean = False
AddHandler dropdownlist.DataBound, Function(o, e) (databoundCalled = True)
dropdownlist.DataBind()
My understanding is that the databoundCalled variable should be set to true, clearly I'm missing something as the variable always remains false.
I need to set a variable , say Flag=1 when a button is clicked.
How do i set the Flag=1 and this variable can be used in OTHER application? Meaning this Flag is set in Program A, then Program B will use this variable (always updated value). I wrote application in VB.NET.
I think app.config isn't that good (use the add key="" value "" ) because when program is executing, it will lock the app.config file.
This Flag variable will be changed according user input (button click) and i try to make this variable use across other application. How to do this?
i am trying to find out how it shuffles the number 1, 2, 3 and 4 without repeating the same number within the series. So far, I think that "i" begins as 1 and RN is a randomized number between 1 and 4. The do while loop checks if "i" is the same as RN and spits out the flag as true or false. Then "i" is increased 1 at a time and so does the number of elements in the array. I believe that the array a(4) and the for loop does something that "remembers" the same numerical value not to be repeated. I'm not sure exactly what the for loop does and how the flag make this thing work.
Lets say, a case where i=1 and the RN=3, the flag becomes false. Therefore, a(1)=3. Then, i increments by 1 and a(j) becomes a(2), which puts out the values 1 and 2. Since both numbers are flag=false, it increments again. Because a(i) = RN, a(2) becomes = 3. How can this be? It has a(1) equal to 3 and a(2) also equal to 3. Each array is supposed to have NON-OVERLAPPING numbers.
The result of doing shuffle() is a random set of numbers that don't overlap:
1234, 1243, 1342, 1324, 2341, 3412, 4321, 3214, and so on.
but never 1111, 1112, 3333 or 3242.
To find out how exactly it works, I tried to delete some lines, tweak the numbers. The result of that is either numbers change to repeats, all zeros or a logical error. The following is the code placed in the module and can be used for other forms and in this case it is used for the labels in form1 windows form:
Sub Shuffle()
Dim a(4), i, j, RN As Integer
Dim flag As Boolean

I've got 2 classes, one called row and one called value. The row class has an array of value as one of its properties.

View 6 RepliesI have a huge array, well Data Grid actually (unbound), but it can be populated into an array... 47 columns by 2000 rows. The data within is random, I need to check each row for duplicates...
essence is on the quickest method though as it will be called by the user. The data is populated by column, so I can not check for duplicates during population.
e.g.
DataFR1, DataBF2, DataJU3....... DataXN47
DataHY1, DataBF2, DataJU3....... DataXN47
DataFR1, DataBF2, DataJU3....... DataXN47 << This is a duplicate >>

In app.config, I supply a cycle string value: "Monday", "Tuesday", ..., "Daily". From that value I wanted to assign a <Flags()> enum. Simply using DayOfWeek does not give me the ability to flag a process as a daily routine. Is there an available .Net class that does provide the day of week as a flag?
In the meantime, I devised the following:
<Flags()> _
Public Enum enumExportCycle As Integer
Monday = DayOfWeek.Monday

View 4 RepliesI have a flags enumeration property that I need to show in a property grid: [Code] In the property grid however, it only allows me to select a single value. I cannot combine the values like usual in a flags enum. How do I show something like a checked listbox in the property grid, so that the user can combine flags by checking items? A None and All item would be great but not required. [url]
But even that does not work properly. It seems to check and uncheck items arbitrarily. If you check the first and fourth item for example, the second and third items will sometimes be checked too. Yes, I realize that is supposed to happen with the TestEnum property (as that defines 'BottomRight' as 'Bottom Or Right', so that's logical), but it also happens with the SecurityFlags for example, which it shouldn't.
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

View 11 RepliesI noticed that if I leave off the terminating double quote for a string constant in Visual Studio 2010, there is no error or even a warning, i.e.
Dim foo as String = "hi
However, the continuous integration tool we are using flags an error:
error BC30648: String constants must end with a double quote.
Is there some language rule in VB.Net that makes a terminating double quote optional "sometimes"? Is there some setting in Visual Studio that will make it flag this as an error, so I can avoid "breaking the build" in this way?
I am having to write a program that randomly selects a picture of a flag. Then the corresponding country needs to be selected and a message box letting them know if they have the right answer or not. I know this isn't near completion but I am stuck on assigning the pictures to the array. The problem I am getting is in the 5 lines like this "Flags(0,0) = My.Resources.USA". VB isn't liking the Flags(0,0) it is saying that a "declaration is expected." The other problem is in this line "PictureBox = Flags(0, x)" the error is "Value of type 'String' cannot be converted to 'System.Windows.Forms.PictureBox'".

3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?
I know I am missing the obvious. I would like a label to show how many cycles in loop are left.
