It's doing exactly what you told it to do.

If you read the documentation on Form.Activate() method, you find that it says: "Activating a form brings it to the front if this is the active application, or it flashes the window caption if this is not the active application."

You're probably looking for the AppActivate() method of the Interaction class, buried in the Microsoft.VisualBasic namespace. Docs on it are here[^].

Yes - buy a book. Or use google to find online articles on the subject.

Also, if you're new to BOTH VB.NET and also databases, learn VB.NET first, then worry about SQL and databases.

Finally, don't be discouraged that you were downvoted, if you do some work and ask questions as you get stuck, people here will be happy to help you.

Hi there,
Actually i'm creating question & answers for the student iQ assessment.

I'm using images as a question's. so wnenever image loaded in the form it only can appear for 10 seconds if the user didn't respond within 10 secs it will go to other image likewise for all the images.

So now i can start the timer but i could restart the timer when the 2nd image appear. i can't use any command button to stop or restart. is there any way to do it.

Pls Help me.

Thanx in advance.

This is pretty simple if you think about it.

You need to write method to get the next question and setup the form. This method then sets up the Timer for 10000 milliseconds (10 seconds). Then enables the Timer.

In the Timer's Timer event, you call that method again, forcing the page to be update with the next question.

Hi Dave,
Thanx fr ur rply. so basically there is few levels in the test. Each level there are arnd 10 images. For every level i'm using 1 form.
Currently i using the 1 timer only & i set the timer interval as 1000. c the code there

private form1_load()
image1.picture=Loadpicture("C:\images\apple") 'question 1
End Sub.

Private sub form1_keypress(keyascii as integer)
if (keyascii=65) then
image1.picture=Loadpicture("C:\images\bus") 'question 2
if (keyascii=66) then
image1.picture=Loadpicture("C:\images\Cat") 'question 3
if (keyascii=67) then
score=3 'score is a global variable
form2.show 'GOTO LEVEL 2
me.hide
else
score=2
endif
else
score=2
endif
else
image1.picture=Loadpicture("C:\images\apple") 'repeat the question
if (keyascii=65) then
score=1
else
score=0
endif
endif

//if (timer1=10)
image1.picture=Loadpicture("C:\images\bus")
else if (timer1=20)
image1.picture=Loadpicture("C:\images\cat")
endif//

so now i don't know how to set the timer event. According to the code here Let's say if the user answer below 5 secs for the que 1,it will give 15 secs to answer the que 2. which is not correct.

pls me help to solve this.

Thanx.

Regards

I'm afraid you'll have to scrap ALL of this code. It won't work with a timer at all.

You have to store all of the paths to these images in an array. You'll also have to store the correct answer in that array. You'll proably need a class-level variable to store the current index that's being shown in that array. Then you can setup a timer. Maybe something like this:
Do NOT copy and paste this "code"!!

Public Class Form1

    Private currentIndex As Integer
    Private flashCards(4,1) As String

    Private Sub Form1_Load()
        ' The first dimension is the filename of the question picture,
        ' The second dimension is the correct answer for that question.
        flashCards(0,0) = "C:\images\apple"
        flashCards(0,1) = "A"
        flashCards(1,0) = "..."
        flashCards(1,1) = "B"
        flashCards(2,0) = "..."
        flashCards(2,1) = "A"
        flashCards(3,0) = "..."
        flashCards(3,1) = "C"

        ' Set the current question number to 0.
        currentIndex = 0
        
        ' Show the first question...
        UpdateQuestionImage()
    End Sub

    Private Sub Form1_KeyPress(key As Integer)
        If Str(key) = flashCards(currentIndex, 1) Then
            ' The correct answer was found!
            currentIndex = currentIndex + 1
            UpdateQuestionImage()
        End If
    End Sub

    Private Sub UpdateQuestionImage()
        Timer1.Enabled = False
        image1.picture=Loadpicture( flashCards(currentIndex, 0) ) 
        Timer1.Interval = 10000
        Timer1.Enable = True
    End Sub

    Private Sub Timer1_Timer()
        ' Question was not answered in time!
        currentIndex = currentIndex + 1
        UpdateQuestionImage()
    End Sub

Why would you want to??

This is going to be a VERY difficult task. VB.NET (the .NET Framework) encapsulates functionality in standard classes that you would have to rewrite from scratch in VB6. There is no conversion tool. Basically, you'd be rewriting the ENTIRE app from scratch.

Hi there, you can try to create an array for each node in the treeview you have selected, and just change the back colour or use a different icon to indicate the selected nodes. You should be able to do that with a litle bit of codeing.

A programmer's life is good... or is it?? Ek dink nie so nie!
