VS 2008 Refresh DataSet By Proxy?
May 24, 2010
I have a form whith a DataGridView.When the DGV is double-clicked another form opens representing a single record. When this form updates back to the database and closes, how can I automatically refresh the DataSet in the original form containing the DataGridView? As it stands now the original form still contains the deleted record.I suppose handling the original form's Focus/Lost Focus events and refresh the DataSet might work, but is this route a bad idea?

I have a client database, with a form which shows a full list of all my clients in a DataGridView. The Load Event of the form fills the dataset - which works fine.
Under the DataGridView I have a link to 'add a new client' which opens a new form and prompts the user for the new client's details. On clicking Save, it excecutes a SQL stored procedure to insert the new client directly into the SQL database. This also works fine.
On closing the 'Add new client' form, it returns to the form with the DataGrid (which was always visible). However, the DataGridView (populated from my DataSet) doesn't show the newly added client.
frmAccounts.TblClientsTableAdapter.ClearBeforeFill = True
frmAccounts.TblClientsTableAdapter.Fill(frmAccounts.DsClients.tblClients)
frmAccounts.TblClientsBindingSource1.Filter = "ActiveClient = 'True'"
frmAccounts.TblClientsBindingSource1.Sort = "Surname"
I made sure the call was being executed by sticking a MsgBox line in the procedure, so I know it runs - yet it doesn't update or refresh the DataSet.This is exactly the same code that is in the Form Load event, so why does it not work? If I close the main form and re-open it, it reloads the DataSet and shows the newly added record.I've also tried putting the code in other Events rather than Form Closing and still it does not work.

I use datasets to hold rows of vendor data and case data and such.
I would like to be able to regularly refresh the rows in these datasets that have been changed by other users touching this same database.
In the app we update like this:
_adapter.Update(_casetable)
That looks through the dataset for rows I've changed and calls the UPDATE sprocs.
Let's say I know that case # 12345 has been changed. How would I cause a refresh of the dataset for that case - getting new data from the DB?

I am a vb.net programmer. I use Visual Studio 2005.I am developing a database application and I use dataset for data binding to SQL Server database. I added a table adapter to dataset and use that data table on the form as data grid view.Then I debug the project and I can't see any column and any data on data grid view. I rebuilt the dataset but nothing come out.

I have a vb.net form with a dataGridView
The dataGridView data source is the dgvTableAdapter with this sql statement
SELECT membres.ID, membres.refere_par, bands.titre,
membres_1.prenom & ' ' & membres_1.nom AS reference_nom
FROM ((bands INNER JOIN membres ON bands.ID = membres.[band])
INNER JOIN membres membres_1 ON membres.refere_par = membres_1.ID)
[Code]....
I know the delete statement works because I saw the changes in the database. If I close the form and reopen it, the dataGridView is up to date.
The membres table is an access table
I'm running the app in visual 2010 debug mode.

I'd like to set the proxy for a web request. However, when I say, for example, request.proxy = "x.x.x.x:xxxxx", it gives me the error "String cannot be converted to webproxy". How can I get around this and actually set the proxy?

ive made a nice program that grabs proxys from a site and adds them to a list box in the format of iport. It grabs around 3k http proxys.
Ive also added another listbox and a button. What i need is to click the button and it will check the proxys from listbox1 and add working proxys to listbox2 but i have no idea how to do this.
I have searched and searched for days now and just cant find one, this project has been on hold for around 2 weeks as i just cant figure it out :[code...]

Is it possible to change/set my Internet Explorer proxy setting in VB.NET application? For example, change the proxy server IP.
If so, do I call and add the MS Web Browser into my toolbox, and add the object on my form to do it, or I'm totally wrong, there are something else I should take care of.

I'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)
request.Proxy = curProxy
[Code] .....
Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.

I am trying to post data to a form on my website. This works perfect.To expand off for personal use and education, I decided to try and add proxy support. I got a list of some proxies, and did it up. The proxies work, and all is good. But, when I try this with this specific example, I receive 1 of 2 errors depending on the proxy used.(405) Method Not Allowed or (500) Internal Server Error.I realize that both of these are being caused from the proxy side of things, but maybe theres an issue with my code?

First off; sorry if i've posted this in the wrong forum, as i'm not sure where best to ask this question as its more a VS2008 question than a VB or Database question. I have a typed dataset in VS 2008 and I have several forms using both ComboBoxes and DataGridViews to display and alter data from an Access 2003 DB.

is anyone else having a refresh issue of the overal IDE. When I switch between my code behind and my form pages in both web projects and windows forms projects, the design page does a complete refresh about 75% of the time. Changing ID names to form controls takes forever due to another refresh.Also, loading of web projects take forever, even ones I have just started that have only 2 or 3 pages in them. It's like the design interface needs an optimization of some sort.It seems to me that Visual Studio 2008 is not as robust and efficient as 2005. When VS2008 SP1 was released, I was hoping I would see these things go away, but they have not. Are these issues that others are experiencing as well, or do I have an isolated issue?If others are experiencing, any ETA from Microsoft on a fix?
