I am wondering if there is any code guide to teach me how to enable the user to draw as many buttons as possible on the windows form and be able to move and resize the buttons on the GUI and also tie the buttons to the timer to toggle the button colour when ever a condition is true

how can i display the datagrid inside the div at runtime.
I am relatively new to programming and have managed so far with google and a lot of patience! I am having a problem naming timer contols at runtime. This is what I am trying to achieve.
1. I connect to my dataset and to my first record
2. I create a loop for the recordset
3. I create various objects on a form and name them using the info in the dataset
I also need to create timers and name them using the first field of my dataset. It needs to be dynamic as its database driven. There could be as many as 100 timers at any one point.

I have a usercontrol that contains a datagridview and a toolstrip. When creating a windows form that contains 2 of the mentioned usercontrol i gate for example c1 and c2 where both contains for sure the datagridview and the toolstrip hving the same control name for example G and t. in my case i want to apply the security on each form, i do this by reading the access of each control inside the windows form and if the control on the form was a user control then i dont consider it as one entity instead but as a grid alone and a toolstrip alone in order to be able to apply its security accordingly. but in ma case, if i want to disable the first grid and enable the 2nd i wont be able to do so since both grids have the same name. is there any solution for the above.

I have already created the provision to allow the user to create and delete the button control at runtime. But now i am stuck at the dragging part. I am planning to let the user to drag the button using the mouse click event and the keyboard (left,right,up and down) key event.
May i know if there is any codes that allow the user to drag the button control around?
the below is my code for the creation and deletion of button controls at runtime.

View 10 RepliesDuring the process of my program I am creating several different buttons depending on what file the user selects. I have been able to create these buttons and I would like to set up the event handler so when the user selects one of these buttons it pops up a message box that shows the user the name of the button they just clicked on. The message box isn't the goal of what I would like to do with it but If I could get that to work I would be able to alter the code to get it to work the way I want it to.
Below is my code that I currently have. I don't have the event handler doing anything at this time as I can't seem to get it to work I am still playing around with it.

View 3 RepliesI would like to recreate the behaviour of a button or command button on an user control. I need to layout a group of this user control on a form so user can select only one at a time. When users click on one of this user controls a selection frame is drawn to indicate that it has been selected. The problem I have is clearing the selection frame when other control is clicked on. How do buttons or command buttons do this? If you layout a group of buttons only one is highlighted. I have tried using different events like LostFocus and Leave and nothing seems to work.

View 5 RepliesIn my Windows Form's application, I enable and start a Windows Form's Timer for a state machine which interacts with various User Controls. In one part of the state machine where an external device is being rebooted, I need to disable the User Interface (a User Control's UI) for the time it takes the device to reboot. The problem exists in that once I use System.Threading.Sleep, the timer that fires the State Machine stops and never restarts. I even re-enabled the Timer and re-started it after the Sleep command but to no avail. Is this expected operation or should a Windows Form's Timer be able to restart after a Sleep?
Snippet of code from a step in the state machine below:
Cursor.Current = Cursors.WaitCursor
MainForm.Enabled = False
System.Threading.Thread.Sleep(8000)
MainForm.Enabled = True
Cursor.Current = Cursors.Default
MainForm.t1.Enabled = True
MainForm.t1.Start()
So I just spent the last 4 hours trying to find out what was wrong with my code, just to find out that there's a bug in this version or I just don't have enough knowledge of VB2010 (I'm coming from VB6, this is my first program on 2010)I removed the rest of the code just to point out the problem, here it simply tries to enable the Timer1 when you receive data in the SerialPort1
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
If Me.Timer1.Enabled = False Then

After this I found that the code inside the Timer1 didn't run when the 100miliseconds passed, so I added a msgbox to see debug.
Private Sub SerialPort1_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived

I need to write some code which draws a predefined circular path (say 48pix diameter) and use a timer to delay it to show it being drawn. I need to use GDI+ to do this. My guess is on the Timer.Tick, I would set some Point value for the next point on the path, and then call Invalidate to raise the Paint event.

My web user control is [code]...
The problem now is that the click event does not fire upon clicking at the button.
I have created two user controls (lets say A and B) and calling then on default.aspx. Both user controls have button named as clear and its event method "btn_clear_click (sender,event)". Actually I like to do something like this: if I click clear button of user control A then it would also do the same tasks defined in user control B's bth_clear_click method. Means, is there any why to call button event of one user control in another user control.
