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.
The program below works fine except for the problem for which The program below allows input of a volume and value which are both successfully drawn to the screen. I will be adding variables to retain the value of each new Volume and new Value input. However, I need code to delete the volume and value graphic numbers drawn to screen when new volume and value's are input. At present new numbers are drawn on top of the existing graphics rather than replacing them. Every attempt to clear, draw over etc has failed. from a very grateful member about to go on holiday and I need this to work for use on hols.
The private sub resetting() does not work but I cannot see why.
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 datagrid, linked to a database. The user of my program can update the database, in one place, then i want my datagrid on another form to update automatically.
i have a div inside a iframe. It will be refreshing very 10 seconds.the div place holder has 4 text boxes controls. if any of the textbox is used then i want to not to refresh the div.
I need to "refresh" a DataGridView, bound to a database table, on a form within a TabControl The DataGridView is loaded correctly on strartup... But if the data in the DataBase change, How do I refresh it to reflect new records or updates?
this is what I am doing in code, after looking for some examples on the web:
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.
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.
I am attempting to refresh my datagridview but it does not seem to work. I have a separate frm where people insert data, and then I have a button on the main frm where people can click refresh once the other frm is closed. I click refresh and yet the data does not update in the datagridview
Private Sub KryptonButton3_Click_1(ByVal sender As
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 have two textboxes...on the textchanged event of one textbox, readonly property of other textbox gets defined...e.g. first textbox is retrieving data as add,update,delete...when the first textbox text is changed to update then & then only second textbox readonly property is set to false...Now the problem,I am facing is....whenevr first textbox text is add,delete,its working fine..& second textbox is fetching the correct data..but once first textbox data gets changed to update,second textbox data remain unchanged though its readonly property gets changed correctly..it shows the same data as it was showing the first time when first textbox was changed to update...but after that,its data is not changing.
It uses a Drawmap() sub with map data to create the map on the game load, but I can't seem to get it to refresh, and then re-draw the map based on player location. For example, if the player walks into a door, then it refreshes the map to show them in a building. Any advice on this? Code below:
Imports System.Drawing Imports System.Windows.Forms Public Class Form1
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.
I have a page that refreshes every 20 seconds and I need to know when it is done refreshing, the DocumentCompleted event does not fire when you refresh for some reason.
I have a datagridview on a form that is bound to a table in a dataset from another class.I use a data adapter to .Fill a table in that dataset and the grid displays the data fine.Works fine.On my form I have a textbox the user can type in that will will pass a parameter to the storedprocedure used to fill this table. So on startup the textbox will have "%" in it. and then the user can type in "F%" and get everything that starts with an "F"
So when that textbox changes I launch an async refresh (.BeginInvoke) to do my refresh. The table gets populated with the reduced number of records (I check ds.table(0).rows.count and it is correct)
But the datagridview then starts throwing datagridview.dataerror events. "System.IndexOutofRangeException : Index # does not have a value".It looks like the dataset is getting filled correctly and not having any issues, but the datagrid is not liking this update. The index out of range error is so common that I'm not finding what I need through searches.
I've got a somewhat sillier question this time. After I insert/update my data using SQLParameters, it wont refresh. I'm using the following code to refresh the binding source:
How would I go about running a query in asp and storing it in an array. Then with the array go through each record without having to refresh the page every time.
For example Sub loaddata() Dim conn As New IfxConnection(connectionstring) Dim results() As String Dim i As Integer = 0 conn.ConnectionString = connectionstring [Code] .....
The results are stored in results(i). Say I have a button that says next and everytime I want it to go to the next item in the results array. I don't want the page to refresh. How do I do that?
I need to poll the server for updated contents. So I added a META REFRESH tag to the page. But it seems that META REFRESH has memory leak issues and it crashes IE.What is the best way to poll data from server continuously? My app is quite old (partly ASP and partly asp.net). I can't invest on technologies like HTTP Push...
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.
I'm using the following code to add a new record to a table in the database. However, the DataGridviewthat's binded to the DataTable, isn't getting refreshed /updated.[code]...
I'm working on a punch-card type program and I'm designing a password change form, so that employees can set their password whenever they first log in, or whenever their password is reset.
The Program works like this: (Code to follow)
1) User starts application
2) User types in their username, and then enters their username as the password. (first time the program is ever run.)
3) The password change form appears, and they enter their desired password in two text fields and clicks OK.
4) The punch-clock form appears, and they begin using it like normal.
The problem I'm having is that at the end of step 3, the program updates an access database, changing the row with the correct username to have the new password. The password in the database changes, like it should, but when the application is exited and then started again, it acts as if the username is still the password.
Below is the code I'm using for the Login Form, the bottom section is a user class that I built just to hold username and password for the logged in user.
Public Class LoginForm 'Creates a new object to house the logged in user's information Public persona As New User
How do I add a row and then refill or refresh a DGV? The row is added/inserted successfully.What I can't work out is how to get the new row to show in a properly refreshed DVG.In one case I keep the old DVG view but the new row is missing.
