I have an mdi child form called "MyChild".
I need to refresh this form by calling the "MyRefresh()" method if the form has focus, and no controls have been clicked on in this form for the last 60 seconds.
Is there an efficient way of doing this ?
In the activate event of the form I could set up a timer and give it an interval of 60 seconds but what about checking for user intervention at any point in that 60 seconds ?
I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated.
The card numbers are in a combobox (which are retreived from an SQL database using the binding source which is linked to a data adapter), and each card has a boolean 'confiscated' field in the database.
It does actually set the card to confiscated after the 3 tries, however I'd like the form to 'refresh' so the card no longer appears in the combobox, without having to close down the form and reload it. Is there a way to do this? I've tried refreshing the combobox and data adapter (.Refresh) but this does nothing
Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?

I had issues in refreshing a form that is bound to different tables in a database. Various forms allow the user to change and add and update information on the form via the database. I had created a public sub in that form that the other forms could call, after saving the data, that was supposed to refresh the data on the main form. This was not working so I researched the problem. I came across this page which pertains to Form.Activated: [url]
I placed all of the table adapter fills into this event, instead of in Form_Load, and it seems to work now, when the form first loads, and when other forms update data. My question is does anyone have experience using this and what are the consequences, if any, in using this to reload/refresh the data showing on the form?
I am working on supplier maintenance file. From mainmenu, opening first form shows records on datagridview through databinding. Clicking add new record, i fired a second form as my data entry with detail view through databinding, minus navigational buttons. I left the delete and save button only. Once through data entry, i save it on server. My problem is, how can i reflect the added record on the first form while i am on my second form? I prefer the new record be added only to the first form. I don't want the idea of retrieving the records again from my server.

I am trying to refresh a datagridview from a second form to display newly written data. I have read the posts on this topic and can't figure mine out. My first form opens and you input data into text fields, etc. and then you need to select items from one table to copy and write to a new table. The datgridview on the first form shows the new table, and I have a new form that pops up to select the line items to add. Everything works perfectly except when I close the selection form after selecting lines, I would like the datgridview on the first form to refresh to show that the lines have been selected and displayed in the datagrid.
My data is loaded into the datagridview as so;

I've been working on this game the past few days, a simple game where two people control different tanks, and shoot each other, very basic so far.The problem I have is when one player is dead. I have the form recognizing each players death by using this code (It's within a timer subroutine)
'Player One Dead
If intPlayerOneHealth <= 0 Then
btnReplay.Visible = True
End If
[code]....
and that code is replicated for every key pressed (Arrow keys, WASD, e, and end). Those booleans are handled in a timer subroutine, where if the boolean is true, they will move/shoot. (Turning the booleans to false is done in the 'Private Sub KeysUp' subroutine)
TL;DR How do I get the game to restart itself when a player dies and hits the replay button?
P.S. I've tried 'Me.Refresh()' as well, and that didn't do anything
I just have not been able to find the correct syntax for refreshing my form. The Labels are added to a shape container and I delete them from it as well. All code seems to work only there is a ghost of the label left behind.

View 14 RepliesPreviously I converted a string with year, month, day and minutes/seconds using
CDateTime(conYear, conMonth, conDay, conHour, conMinute, conSecond)
This code will no longer work in VB.net and I cannot figure out how to do this with 2005 VS. The string originally is something like "20100310142715" and should be broken down into year, month, day, hour, minute, second.
I'm having an interesting issue that I can't reproduce on a different project, but can consistently on this one. I have no clue what might be causing it, but am hoping that someone may have seen it before.
I have a main form, from which I run a series of checks. On this form, I have a listview control. Because of some issues with the refreshing of this listview control, I had to create my own messagebox. It's just a form that displays some text ( it also happens to look nicer than MsgBox; in my opinion, anyways ). It's been working great for months, until recently.
My problem is that on my main form's load event, I run this check, which returns an error within a try/catch block. I then call my custom messagebox with a message. It in turns calls it's ShowDialog() function.
In any other situation ( after the main form has been loaded ), I have no problems. The messagebox goes on the screen and behaves appropriately ( ie: waits for my input and acts as a modal dialog ( stops execution of my main form's thread ) ). However, on this onload event, my messagebox comes up and goes away almost immediately afterwards.
I've traced it all the way to the showdialog() call. For no explicable reason, it appears to skip right over this call, without me doing anything on the form.
Here's what the inner trace looks like ( when I put a breakpoint on the onclosing event for this messagebox form ):

View 1 RepliesI have a databound combobox that displays a list of items, and I have a windows form that opens after clicking a button that allows me to make changes to the table that the combobox gets it's values from.

I have a windows form application that will open other forms, but will only display the forms for a few seconds (user configurable). I would normally do something like threading.thread.sleep(n), however when doing this the forms controls do not load only the white background shows, and I have also been reading that this isnt the best practice for what I am after as user input will not be actioned until the thread wakes up.
I have come across people using System.Timers.Timer(n), but I am struggling to get this to work for me, the form will only open and close straight away (you can only see a flash as the form opens then closes).
The code that I am using is:
Private Shared tmr As New System.Timers.Timer
aForm.Show()
tmr = New System.Timers.Timer(aSleep * 60 * 60)
[Code].....
This is all contained within a Private sub that passes the form and the defined run time.
My intention is to have the main application running from the task bar, which then calls one of the forms that will display for a defined period of time, close the form, then call another one of the forms.
Is any able to point me in the right direction for why the form opens then closes without seeing through the defined run time (I have been testing with 10 seconds), or is there a better way of doing what I am seeking?

Everytime I execute my program, the main form closes by itself after about 15 seconds. The code is not the problem because it does the same thing when I put the whole code in comments. It's also not a key problem because it closes by itself even when I don't touch a single key when it's running.
