If (IsPostBack) Then
HandleUploadedFile()
End If
Dim savePath As String = "Images "

When I trace my code I find it goes to the second if and then go to end if without running the code inside the conditional.
I have some code in Form Load event. It is doing fine. But when it reaches to pick data from database, no commands are executing after that. There is no error at all but it just goes silent.[code]...

i want to load up my.settings and 1 list will make new toolstripdropdownitem and the other lists is for the tooltiptexts
or I could do it another way, but how can I check the index of items in a my.setting string collection? like if I want to get the text of index number 3 how do I do that?
I am using Microsoft Visual Studio 2008 with VB.NET, and in class we were assigned this project: A procedure should calculate a 2% price increase on all red shirts, but a 1% price increase on all other items. In addition to calculating the price increase, the procedure also should calculate the new price. You can use the variables strItemColr, strItem, decOrigPrice, decIncrease, and decNewPrice. Format the original price, price increase, and new price in the lblOriginal, lblIncrease, and lblNewPrice controls, respectively.

Okay I need two blocks of code for each of these:[code]Now both of these are under the if statements checking if the startsWith or equalsIgnoreCase check boxes are checked. (Only one is under the corresponding code not both.) At runtime when I check off the boxes neither of these two code blocks execute.

I am very new VB .NET and just starting If statements. My problem is: Write an If statement that determines whether the variable CurrentBalance is greater then 1000.01. If it is, multiply the variable CurrentBalance by 1.005. Otherwise, multiply CurrentBalance by 1.007.So far I have
Sub Main()
Dim currentBalance As Boolean

I really don't even know if thats how I should be starting. Not sure what to put after the first Then on how to make it multiply currentBalance by 100.5.
Are the following 2 SQL statements the same? Will they produce the same results?
sql1 = "SELECT * FROM [StudentDetials] WHERE ([Subject1] LIKE '" & Subject(0) & "' OR [Subject2] LIKE '" & Subject(0) & "') AND ([Day1] LIKE '" & TabDay & "' OR [Day2] LIKE '" & TabDay & "') AND ([Time1] >= '" & Time(0) & "' AND [ETime1] <= '" & Time(1) & "' OR [Time2] >= '" & Time(0) & "' AND [ETime2] <= '" & Time(1) & "')"
sql1 = "SELECT * FROM [StudentDetials] WHERE ([Subject1] LIKE '" & Subject(0) & "' AND [Day1] LIKE '" & TabDay & "' AND [Time1] >= '" & Time(0) & "' AND [ETime1] <= '" & Time(1) & "') OR ([Subject2] LIKE '" & Subject(0) & "' AND [Day2] LIKE '" & TabDay & "' AND [Time2] >= '" & Time(0) & "' AND [ETime2] <= '" & Time(1) & "')"
In my case they simply produce the same results but that's because of the data i'm using.
I have a general query that I need clarifying by some intelligent boffins such as yourselves. I have the following code in a function:[code]Obviously the Dispose method will never be called on the site object or the helper object.

Is it just by the fact that the enclosing method they were created in has been disposed of?![code]

View 9 RepliesI just want to know how to create a prepared statement in VB. I know in java one would use ? and these would get replaced. I am aware that in VB you use @ParameterName. Basically my code gets down to where i use the prepare method and the error i get is that my syntax for my insert is incorrect. To me it seems that the parameter is not getting substituted in the insert statement
Eg.
Dim cmd As String = "insert into sites(id) values(@id)"
Dim odcmd As New OdbcCommand
odcmd.CommandText = cmd[code].......

I am trying to create a program that calculates the prices of different payment methods of a buffet.The program requirements are simple. The buffet start in 1/7/2011 and ends 31/8/2011. Payments methods are online, cash and coupon. coupon is only valid from 1/8/2011 to 31/8/ 2011. 1 child is free for every 2 adult that pay. There are different prices for weekends (sat and sun) and different prices for weekdays. [code]
View 3 RepliesMy product owner has asked me to make some comparision logic configurable so the process engineers can change things without making code changes. Currently the code is a SELECT CASE statement with various IF THEN statements that are fairly standard.
The problem I can't seem to find a way around is that he wants through configuration to AND/OR a variable number of comparisons in the IF THEN statements. His idea is the that the configuration would work like a limited query builder for the process engineers. The only solution I've come up with is to build a function in a string and use the VBCodeProvider to compile it at runtime. Is there a better way to approach this?
i have a program, three radios, and 2 check boxes. the Radios use a constant value and do a multiplication. check one applies a discount. no problem.
the last takes the values of all three radios does a comaparison and displays a label if false, performs a subtraction if true and shows savings.problem>
very convoluted using if statements. and the output is often wrong(i know this is a logic error) i can not find the fault.
would it be easier to use case statments. can and will post code if requested. as it is in if then format currently it is rather long.
Sometimes the answer is so blindingly obvious i fail to see it.
I have a method that I want to check to make sure that both integers entered are both positive:
Public Function BothPositive(ByVal num1 As Integer, ByVal num2 As Integer) As Boolean
If (num1 And num2) > 0 Then
Return True
Else
Return False
End If
End Function
Now if I were to enter some numbers in
BothPositive(1,1) = True
BothPositive(1,2) = False
BothPositive(-10, 10) = True
Why is this? What is going on with the order of operations in the comparison statement or what is the "And" trying to compare? I don't see why this wouldn't work.
