I've made a simple program that set environment variables like [code]...
If I close de command prompt then open it again, it's OK.
How can I refresh the environment variables in the command prompt I use my program?
I am wondering if I can use VB.NET(I am using visual studio 2010 express) to get and set a environment variable.
I want to add path of my application on system environment. I want to preserve what is already there and then I wan to add my string. This can be done by getting value of PATH and then append my string then re writing it.
I have 2 questions here:
How to get/set system variable in vb.net 2010? Will it be on the fly, I mean will it be immediatly avaialble in dos prompt or there will be delay?
As just for experiment i opened a command prompt then updated the PATH variable manually and it was not updated. I am wondering it I do it through programe it will be same.
I was trying to use the sentence
Environment.SetEnvironmentVariable("CLIENTIP", <value>)
but the variable is not created. I used both an string variable and a constant to set the value.
So, how can I do this to work?

I think my title covers the high level, but for indepth; i need to be able to connect to a machine through and ip and set a enviroment variable, i have over 60 machines in different states all on one network that i need to do this for as well as someother things for the machine. currently this is being done through a PCEXEC command in a batch file they want more control on how this operates. I just really have no idea where to even start looking for the enviroment variable change(setting one on a machine that the app is running is simple we all know that. but on a external machine im lost) on a remote machine.

View 2 RepliesI 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?
View 3 RepliesI 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.

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.
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 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.
View 4 RepliesIt 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.

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.

View 4 RepliesWe have a couple of applications at work that need a reference to the license server set in the User Variables under the Enviroment Variables on the windows xp client machines(system properties, Advanced, Enviroment Variables). The problem is that both applications needs a reference to the same variable name and you can't have two with the same name. What i intend to do is to create a simple windows application with a button for each application that deletes the variable item present, adds a new variable item with the value needed for that application to be able to run and then run the application itself. This is just a temporary fix until we get a more permanent solution. The 'GetEnvironmentVariable' class in vb is not able to add or delete a item, maybe the WIN32 API could do the job.
