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.

I created a small vb.net console app in visual studio 2008 trying to learn .net but my results show differently when I break in the code and press F11 to step through. If I do it this way, the results I expect to get show but if I don't break into the code the results aren't what I'm expecting.
Basically everytime I click a button i want to write four numbers that are random. If I break into the code, these show random numbers i.e. 1 3 4 3 but if i don't break into the code. my numbers are all the same i.e.1 1 1 1. Here is my code, like I said I'm still learning so the logic is probably not correct.

I want to do this:
lblQuestion.Text = "Text (insert line break) More Text"
We can reproduce it to the point it happens whenever we click Tab, but short of putting a break point at the beginning of every method in the project to find out what is executing.
Is there a way to set visual studio to break whenever anything executes?
When I am in break mode, I cannot update code.I receive message "Cannot currently modify this text in the editor. It is read only." Can anyone explain why I get this message?
View 1 RepliesFrom my initial readings on unit testing it is wise to put all of your setups and tests in a separate project from the code being tested.I've recently begun reading The Art of Unit Testing, trying to discover how to break dependencies on things such as database calls.The methods offered involve changing areas of the test code, such as adding specific interfaces and "stub" methods to the production code.This seems to defeat some of the good things about keeping tests and production code separate.Is there any recommended dependency-breaking technique that doesn't involve changing production code?
View 3 RepliesThere has to be a setting for this somewhere, but for the life of me I can't find it. When I "Start Debugging (F5)", if there is an issue with my code, I get a "Build Failed" notification, in the lower left of my screen. I would like to be directed to the location of the failure. So far I have been lucky and have been able to find the offending code but this is getting scary .

-new Dell laptop without a Break key.
-VB6 and VS2008 IDEs use Ctrl+Break to pause execution for debugging.
-I need a way to map another key combination to trigger a Ctrl+Break
My setup may make this easier or harder but to be clear I am running Kubuntu 9.10 (latest stable) and WinXP in a VirtualBox VM. Obviously all VB6/VS2008 dev is taking place in the virtual machine.So maybe it's possible to have the linux host send through Ctrl+Break based on a key mapping, or maybe it's possible to remap directly in WinXP. I'd settle for any solution as atm I need to use the XP On-Screen keyboard to send a Ctrl+Break.
This is an IDE question for VB Express 2008. It might be a bug in the IDE, or maybe it's my fault somehow?
My main form is named FrmMain and in my application's properties I have set frmMain as my startup object. All of that seems like what a lot of coders do.
But while debugging I hit Ctrl-Break, as I have done for years, and I get an behavior in the IDE that I wasn't expecting. Upon doing so, I get the green background text and the green arrow indicating in a tooltip: "This is the next statement to execute when this thread returns from the current function." Even if I didn't have the designer document open, it automatically opens frmMain.Designer.vb in the editor and hihglights line in green. The line is of course: Partial Class frmMain which is line 2 of the file. (Yes, it's highlighting the second line of the designer-generated code.)
The thing is, frmMain seems to have fully loaded and it's my startup object. As far as I know there shouldn't be a "next statement to execute" at all because code should be idle. I don't want to see the Designer.vb document... I want to edit my own code. Even though my form is behaving just fine, could there somehow be an unfinished aspect of loading the form such that it is "not returning" from a function?
Edit: In response to a couple comments, I'm adding three screen shots:
I'm writing something that will examine a function and rewrite that function in another language so basically if inside my function F1, i have this line of code var x=a.b(1) how do i break up the function body into symbols or "tokens"?I've searched around and thought that stuff in System.Reflection.MethodInfo.GetMethodBody would do the trick however that class doesn't seem to be able to have the capabilities to do what i want..dit 2:basically what I'm trying to do is to write a program in c#/vb and when i hit F5 a serializer function will (use reflection and) take the entire program (all the classes in that program) and serialize it into a single javascript file. of course javascript doesn't have the .net library so basically the C#/VB program will limit its use of classes to the .js library (which is a library written in c#/vb emulating the framework of javascript objects)

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
