I have a for loop condition as below coding for looping to change word on label.text, but as a result, it just only display the last value.
how can I do to display each value for a looping.
i want the result is the label1.text to show 1 then 2, then 3, then 4.......finally is 10.

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.

I have a label called lblMessage. The data of the message is saved in a SQL Server 2005 DB. In my table i have a message ID and then 4 rows with my message ID.

What is the correct syntax to go to the next sequence in a loop if certain conditions are met bypassing the contents.
I am using goto and inserting a line number which is probably not the best way.
I.E. My syntax:
For i = 0 to 100
If i = myvariable goto 100

I am developing a testing application consisting of 50 multiple choice questions each with 3 radio buttons to select the answer choices for my workplace and I just had a couple of questions concerning storing user input for review and displaying the next and previous questions. First - Would it be more practical to display each new question and the answer choices on a completely new form or in labels and just have the click event procedure of the Next button change the text properties of the labels and display the new text? Second - I want the application to store the user's answer choices so that at the end of the exam they can see how many they missed, which ones they got wrong, and then print the graded result. I have no idea how to store the input for later review and printing. Lastly - I would like the user to be able to mark questions for later review as they are taking the exam. For example, if the user selects an answer that they are not 100% sure of, the can mark a checkbox so that at the end of the exam they can review the answers they were unsure of. I guess I am just looking for some direction in developing this type of application. As of yet I have only done simple projects for school and this to me seems a bit out of my league. I have already designed the user interface and created a TOE chart but I would like some input on how to actually code the application.

I created form2 in which there was a Label to display processing status text. In form1 right before serial port ran I used Form2.Show() and Form2.TopMost = True to display processing status. However only blank Form2 was displayed without any text inside, which means the Label in Form2 was not running. But after serial operation was done, the text in form2 came up, at which time I need to close it.

I'm using a loop condition to check if there is null value in the columns, then remove it.
-Original author
[STart:]
For i As Integer = counter To dt1.Columns.Count - 1
For x As Integer = 0 To dt1.Rows.Count - 1
if some condition then
something = true
[Code]...
Sometimes it runs correctly and sometimes even though when i becomes greater than (dt.columns.count - 1), it still executes the for loop and throws an error that there is no column with that index. I must be missing something here but I'm not able to debug the issue.
My application uses 12 checkboxes. Dependant on the status (checked or unchecked) different action are required. I can't seem to be able to structure a for next loop to do this.
View 7 Repliesform1 have four buttons, i want to set a label text in form2 according to which of the button on form1 is clicked.below is what i tried so far.on form1 each of the button click event i made it focus

Me.Focus()
Form2.Show()

If Main1.Answerbtn1.Focus Then
Label2.Text = "You choosed option '

the above code displays only the first condition ("You choosed option 'A'"") on the label when any of the button is clicked?
Those who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.
