I dont have a very good background in vb, so hopefully there is a simple way to do this.Basically what we have is a vb timer that is counting time is seconds. After fixed amounts of time, in this case 2 seconds, the if statements trigger certain events. Essentially what I want to do is say: after timer reaches st*2 (18 seconds) then restart the timer at zero. Is there any way to do this?
View 4 Repliesi have a coundown time in which will trigger once i run my main screen in my "MAIN SCREENFORM" ....... I create a "RESET button" on other form call "FORM2" , now the problems is how should i write the code when i click reset button it will reset the count value my lblcountime.text and start re-countdown again from the start?
Public Sub MainScreen_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
timeleft = 120
lblCountTime.Text = "120 seconds"[code].......
We've set code to fire certain valves on the timer but once it gets to the last valve (checkbox) I'm not sure how to reset the timer to start back at zero so that it refires the sequence.
Here's the code:

ByVal e As System.EventArgs) _
Handles Timer1.Tick

How to make a timer with a reset button and three text boxes with hrs, mins, and secs.
View 14 Repliesi have a textbox with hexadecimal values and i would like to use the slidebar/scrollbar to change the values (increase/decrease) then save the final values to a text file. To prevent the program from writing to many times to the file, i decided to use a timer. As long as the user still making changes or controlling the slide/scroll bar the timer will re-load (5 seconds). When the user is done modifying (no more dragging or clicking on the arrows) at that time the timer already expired, then the value get recorded to the text file.

I'm using a System.Timers.Timer in a service that seems to keep ticking after it has been disabled. I'm using autoreset = false so I would expect it to only tick once unless I start it up again. I'm calling stop again, just for good measure, but the timer keeps on ticking.I'm using VB.NET in .net 1.1 and don't have the option to change frameworks.Here is a simple console app to reproduce the issue. This is not the actual code from the project.I believe the interval is long enought to prevent any thread issues in raising the event multiple times, but I will admit I'm not a threading expert.

In the first loop once it cycles through once it does not reset the data so it continues to hold the previous data so therefore the outcome is incorrect. Can I reset it to start back at 0?

View 1 RepliesI have been battling with resizing a form in code, using either a timer or a for loop. When I say resizing, what I want to do is create the effect of a rolldown/rollup window. On my form, I have a groupbox with search criteria options, and underneath the groupbox, I have a datagridview with several buttons.
The effect I'm trying to create can be seen in Windows XP Security Centre; when you open up the security centre screen, you have your firewall, automatic updates and virus protection areas; to the right of each, there is a small round button, with either an up or down arrow, depending on whether the section is rolled up or down. When you click the button, the section rolls down or up smoothly.

I have a For/Next Loop that adds values to column in a DataGridView. I want to set up a timer to slow the For/NExt Loop down. So the DGV will load and then the user will click button on the form and the DGV will have numbers added into all the rows of a specific column. For simplicity, assume I want to load the numbers 1-100 into each cell and I want to see each number as its passed.
I am not sure how t set up the time to work with the For/Next Loop in the Button1_Click event. Do I have to use a Timer1_Tick event as well and somehow associate it with Button1_Click event?

I got on my form textboxes, checboxes but also a groupbox which holds texboxes.
The idea is to be able to clear and reset all of these by clicking a reset button.

But ofc Me.controls isn't gonna get involved with the stuff in the groupbox.

Select Case True

It goes through the Do loop and the For.. next loop but doesn't change the label. Visual Studio doesn't show any errors when I'm writing the code, but when I run it, it hangs somewhere.

Ok, so I am building my own program to control a video player I have through telnet, I have everything else working except one thing.I have a reset button to reset the player, when I press it, it sends the string "Reset" and the unit resets without a problem.But when I add a code to close the winsock connection upon reset, it doesn't send the string to the unit. I am sure what is happening is the winsock is getting closed at the exact same time it is trying to send the string and so it fails to send, how do I make it close winsock AFTER the string has been sent?

View 1 RepliesWhen I view the Tab Order in VB 2008, everthing has a tab order number and it is in decimal form. If I click on each item, it appears that I can set the Tab Index but it is hard to see a correlation between the Tab Index and the Tab Order on the form. Most of the items on the form are not going to be tabbed to by the user.
1. Is there a way to clear the tab order and only tab to the items that the user would use and in the order that they would do it?
2. What number should the tab order start with and do you start over with the numbering on each form?

It's good to be back in this forum again hoping someone could help me solve my problem again xD My goal is to import .txt to db.
This is my code

Some of the records are inserted but when the code read the part where there is an empty/null value in the column where they are assigned as "decimal" the error message "Error converting data type nvarchar to numeric." pops out.
I am trying to reset all integer values to "0" with a reset button.I try not to use hardcoding by simply set them one by one. So my idea was checking all the variable's type and set them all to "0".
I tried to use this methode, from someone in this forum (sorry, I forgot the name but this is very helpful...) For Each ctrl As Control In Me.GroupBox4.Controls 'Check and see if this control is a TextBox
If Object.ReferenceEquals(ctrl.GetType(), GetType(Label)) Then 'Check and make sure this s the "TextBoxToExclude"
'CType(ctrl, CheckBox).Checked = False
CType(ctrl, Label).BackColor = InactiveColor
End If
Next
But when I tried to find the code, I couldn't get it.So, if anyone knows how to do this,
