I want to write two nested loops and inside them "two if statements" when I write an Else statement which has a messagebox saying that ID is not found.. it repeated many times depending on the for loops. I only want to be displayed once !!! but when I wrote my code like this (using exit sub), the message appears when the condition is right and appears when the condition is wrong. I tried to move this statement somewhere else but still I have problems with it.

I have a question about using nested IF statements in a SQL query. I have a select statement that calculates a semester grade -- Dim sqlStr As String = "SELECT 'XXX-XX-' + right(socSecNumber,4) As [Student SSN], Round((firstExam + secondExam +(2*finalExam))/4, 0) AS [Semester Average] FROM Grades that I am displaying the results in a datagridview. I can successfully display the masked social security number and the Semester Average but I also need to convert the Semester Average to a letter grade to display in a newly created column for Grade. Can this somehow be done with nested If or Case statements within the SQL statement or is there a way to pass the Semester Average information as a variable to a nested vb If statement? Basically, I am needing to know how to display the letter grade to the datagridview using this criteria:

I'm using a series of nested if/then/else statements to make sure a user enters information into each text box or chooses a radio button. What would i use to say if no text is entered in textbox1, then ... also what would i use to make a sure the user choose one or the other radio button? for example i also have a combo box, i used "If SubjectComboBox.SelectedIndex <> -1" for the if statement.
View 2 RepliesNow I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

How i can jump from one form to another form in same project in vb.net 2008
View 5 RepliesI have a form with textboxes for entering data. One of the textboxes is for entering a value that is always one character. How can I make the cursor automatically jump to the next control when a character has been entered? I'm thinking the key press and release event and then set focus but is there a better way?
View 3 RepliesI have written code to download a webpage HTML source code into a .txt file, once downloaded, the code I posted here adds all lines as strings into a list and is supposed to find an anchor point as a position reference and then jump down the list to the real keyword.
I have an anchor point in this list that is a constant that I will always "know of" but I need to jump down 3 lines below this anchor point to the real keyword I'm looking for that is always "unknown to me" since it's a variable.
My anchor point is the keyword Hair Color which both the words and the line they're on are unique in the entire source code. My target keyword is the variable Brown (in this case), that I can't target directly because neither it nor the line it's on are unique and will change from query to query. The HTML table source code like the one below is always structured the same but some pages may vary in layout depending on the keywords applicable on the webpage. The code structure below however is always a constant, you can always count on all the webpages that the keyword Hair Color is always the 3 line into the table row and its variable is always 3 lines below that. So even though the answer I'm looking for is always 3 lines below my anchor point, my anchor point will not always be on the same line of code in the source code.
HTML code in the .txt file:
<tr>
<td class="paramname">
<b>Hair Color</b>
[Code].....
I may not be using the code correctly, through my attempts I don't know how to do that jump.
how to "skip" or "jump" down lines in my list by predefinition like: "ok, I found my anchor point, now I'm supposed to jump down 3 lines and pass what ever I find there to a string!""ok, I found my anchor point, now I'm supposed to go to the second instance of the keyword Brown from here that I find and pass what ever I find there to a string!"
I am not sure what to do with the following. The code below reads from a massive list of phrases, checks for a certain conditions and if all succeed a) adds the output to the new_question list b) keeps the value of the variable incremental to "level_0".
If the fourth "if statement" fails, the code changes the value of the variable incremental to "level_1" and jumps to a second case statement. The problem is that for certain input the code fails form the "third if statement" and execution refuses to jump to "level_1" (bacause the fourth "if-statement" must fail as well). I tried moving the "incremental variable" between the third and the fourth "and if" but since the code reads from a list of phrases even if it returns true, execution jumps to level_1 (as some phrases fail from the third "if statement"). I hope I am making sense

View 5 RepliesI am trying to make bounds for a character that can jump. I have made the character graphic into a rectangle and I have a square block in the game that the character must jump onto and I have set that as a rectangle.
How would I make it so when the character jumps onto the square block, he stays up there and then when he jumps down, and touches the ground, he stays on the ground. My current jump code is standardized; it does not detect changes in the Y-coordinate. What I have done in the jump for the character is I have made it so the Y-coordinate is increased by a certain amount and decreased by the same amount so the difference is equal to 0.
For example:
Character.LocationY += 8
Character.Location -= 8
Say I have this in VB.NET:
Dim executeB As Boolean
Select Case myVariable
Case "a"
'some code
Case "b"
'some code
Case Else
End Select
If myVariable is "a", control will go into the first case statement. Now let's say if myVariable = "a", but inside a's case block, I find that executeB is true, is it then possible to jump to the second case?
