Refreshing A Flowlayout Panel?
Jan 28, 2012
I wrote a piece of code that will create text boxes inside a flowlayout panel on a form using the number of records that are selected from the database as the loop counter. I can get the program to work the first time through but on the next attempt the text boxes that were displayed in the flowlayout panel are still there. I have tried using the clear property of the flowlayoutpanel but that did not work. I have also tried a new instance of the flp that did not work either.I have taken the code apart and all of the individual pieces work except for this part below. The way I tested this was to input a # and then run it again with another # and I want the # of boxes to change without closing the form.

I'm making a plotting program. The panel (vs picturebox) is necessary because the data doesn't all fit into one screen so scrollbars are needed. I'm using graphics to draw the background layer and buttons for the data points.
When I scroll, the background is redrawn incorrectly since the top left corner of the panel is no longer the top left data point. Ideally, I'd like to prevent the background layer from redrawing entirely (after the initial draw). Alternatively, how do I take in consideration the new position of the scrolled panel in drawing the shapes & lines in the background layer?

I would like to add an effect where a panel sweeps out of the way to make room for another panel. This is sort of like a sliding effect, and I think at one point in time this could be seen on Apple's website under their product pages. I came up with some code, but it isn't working.

When a user is editing a given piece of data, they're allowed to add messages/comments. These are stored as child records in a SQL database. Clicking on the Add Message button brings up a panel (pnlMessage) courtesy of the AJAX ModalPopup Extender. This takes some input and, when the "Send Message" button in the panel is clicked (I learned the hard way to NOT make that the 'OkButton' property), the message is stored in the database and an email is sent to the intended recipients. No problem there.
However, I need to be able to allow the user to add new email addresses (so long as they are registered in our database). I have another ModalPopup / panel combo (pnlSearch) that's tied to a button on the previous panel (pnlMessage).
The user is supposed to be able to add an email or click on a search button to populate a list to choose from.
The pop-up panel (pnlSearch) comes up just fine, but clicking the "Lookup" button (which instigates the search and returns a collection of records that the user is supposed to pick from) closes the panel.
Previously, I ran into the problem of having the Button.Click event never firing when I put the Button into the "OkControlID" property (the CancelControlID works fine since I don't want to do anything). Removing the "OkControlID=Button" line allowed it to work perfectly with the Button.Click event firing as expected.
So now I have the Search panel with a button for "OK" and a button for "Search" - but the panel should stay up and visible after the Search.Click does it's thing. Am I missing some property that basically says "don't close the panel when this button is clicked"? Of course, if I bring up the panel again in the same session, the results from the previous effort are there (the search results).

I have a TopBar, A LeftBar, A VScrollBar, A HScrollBar and a Panel inside a SplitContainer Panel.The issue I'm having is that when my SplitContainer Panel is small enough to enable one of the ScrollBars, I will slide the ScrollBar and then when I resize the Split Panel, my Panel1 is staying where I scrolled it too.I'm having troubles thinking of the correct code to fix this.

I'm working on a visual studio 2008 VB.Net project (.net framework 2.0), and am having some trouble with the Panel control using a fixedsingle border. As a small example of the problem, suppose I have one Panel2 contained inside of Panel1. If the Left position of panel2 is set to 0 (meaning it's border is up against the left edge of Panel1), the left border will show as bold, and slightly indented.
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
Inherits System.Windows.Forms.Form[code].....
What I'd like to see is just a single line, not bold or indented, where the two panels borders are equal.Is there a property or custom paint technique I could use to achieve this behavior?

This is for a mapping/plotting program.
t.panel is the main panel and it has too much content to fit in one screen so there are scroll bars. x.panel contains the horizontal scale for the data points in t.panel. I drew the scale using a bitmap and set it as x.panel's background.
Setting x.panel's horizontalscroll.value = t.panel's horizontalscroll.maximum doesn't seem to work. I think this is because x.panel's doesn't have any content that causes it to need scroll bars.

I have a problem with a certain panel in another panel.
I have declared a panel on my mainform that is called panel1 ( dock: fill)
In this panel is another panel ( panelmain )with size 10.000, 10.000 pixels. Now I put the auto scroll property of panel1 to true, so then the panel1 has scrollbars on both sides and can show the whole panelmain.
Now the user has the ability to zoom, which basically means that I just scale Panelmain with all it's child controls.
Like Panelmain.Scale(0.95) ( To zoom out )
And panelmain.scale( 1.05) ( To zoom in)
This works well, but when the user is using the scrollbars in panel1 and after that zooms in ( or out ) the location of panelmain is changing. So I tried to solve this by docking panelmain inside panel1 at the left. But now the vertical scrollbar is gone. how I should dock panalemain inside panel1 to prevent panelmain from moving around but also in a way that both the horizontal as the vertical scrollbar are present?

In VB6 I could embed a panel or picturebox containing controls or images within an outer panel or picturebox. If I moved the outer control then the embedded panel would move with the outer panel and stay in the same relative position, which is what I require. This doesn't seem to happen in VB.NET, the internal panel stays fixed in its location, even if I have pasted this panel within the outer container. Is there are trick to this or do I have to code to get the internal panel to move with the outer one? How does an internal container remain embedded within an outer one?

I have a form that uses a tab control. On the main tab is a DataGridView containing Customer information. If I double-click on a row in that DGV, I go to another tab in which I can either make changes or delete the record. Whatever I do, whether it be delete it or modify it, after clicking on the appropriate command button, focus goes back to the main tab. What I wish to do is have the changes be reflected on that DGV. If the record is deleted then I want the DGV to not have that record present. This DGV is bound to a BindingSource. What control/dataset to I need to "Refresh" in order for this to happen?

I have a VB (2008) program that I wrote that will not refresh the info in a textbox. I've tried to refresh, update, hide/show the data but cannot get it to work. Here is a code snippet:[code]The concept of what I'm trying to do is quite simple. the user selects one or more sites to check, the program shells out and SSH's into the device(s), grabs the output an parses the data. It then turns different boxes to different colors based on the output. The maddenign thing is it works for the first time through and sometimes the second, but never any farther.At the end it paints everything just fine and if I insert a blank msgbox within the code it refreshes fine as well.

Actually i want to add a "Refresh button" at the client side such that when it is pressed some specific lines should be executed at the server side.(e.g. when the "refresh button" is pressed at the client side, the server should evaluate some variable "data" and executes this line "winsock.sendData(data)" ) OR Can i set my server to refresh every 30 seconds or so to evaluate some variable and then execute the line "winsock.SendData( )"? is there a way to accomplish any of the above?

I have a datagridview control on my form which i have populated it with values from a dataset. Now i am using a button to delete these values from the database which is working perfectly for me but the problem now is anytime i delete the old value still shows in the datagrid which shouldn't be so so i wrote the code to refresh the grid after deleting but is still not working for me as i want.
I am using this code:
Me.UserAccountsDataGridView1.Refresh()
But onething is the value i deleted doesn't show when the form reloads again. but at run time it still has the old value in it again.

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;
Public
Sub ShowVoucherLines()

I want to update the contents of a combobox in a VB program. So I change the underlying data structure (which is an ArrayList), and according to the documentation in [URL] there's a RefreshList method which should do this. But Visual Studio tells me that there's no such method, and when I type it in manually I get an error saying that RefreshList is not a member of System.Windows.Forms.ComboBox.

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 am in need of a method to refresh a webbrowser object's IP address. Until now, I've just change the value in the Registry. However, the webbrowser only gets the IP when it is first instantiated (when it first navigates to a web page). So, it will not update every time I change the registry. I know there is a way to simply change the IP of the webbrowser itself, so that it will update the IP every time the command is run in VB6, however I have no idea how to do this in VB.NET.
