Auto-refresh Windows Form - Sub Form With A Datagridview ?

Apr 16, 2009

I am working on VB.Net. I have a sub form with a datagridview, that is being loaded with the criteria taken from another form. Hence this form is called with parameters.

Here is the code that calls the sub form.

Code:

where ds is the dataset to fill the datagridview and rb is the string from a radio button on this form.

Here is the code in the sub form.

Refresh Combo Box In Windows Form?

Mar 9, 2010

I have a Main form (a window form) in VB.NET which has a Combo Box to display a list of countries. A sub form activated from a "Button" on the Main form allows users to add Countries to their list. But After Adding a new entry the Combo Box on the Main form does not show the update (while it is still open). I have to exit the main form and relaunch it to see the update.

The populate function in shown below. I call this method after adding new countries but still; not good. I have used Invalidate function of combo box but of no use as well.

Public Sub PopulateCountry()
Dim rsLocal As New ADODB.Recordset

C# - Stop Developers From Calling System.Windows.Forms.Application.DoEvents()?

Mar 15, 2009

We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:

Add checkin gates to source control?

Developer training?

Code Analysis rules (why is this not already a built-in rule?)

How to I enforce a coding practice?

Stop Webbrowser Objects From Stealing Focus If Auto-refresh Header Is In Use?

Jul 12, 2010

I have a VB.net form which has two webpages embedded. The webpages have a 5 second auto refresh built into the HTML header as the information is constantly changing.

The problem I have is when I pull up a secondary form, I lose focus to the 'Main' form everytime the webpage refreshes.

Is there any way to stop the webpages autorefreshing in the form and I will build in a refresh command into a timer I already have in place and then I can start and stop the refresh at will.

Unfortunatly I cannot amend the source code of the HTML as this is required for a different process elsewhere.

'abort' (terminate Immediately) A Form Screen In A Windows Form Application Running Under 'local' Environment?

May 30, 2012

FormA calls DialogB where user cancels DialogB which exits via ForceTermination(), see insert.Caller FormA check for DialogResult not = OK, which it isn't, and I can see this in debug as Abort(3).However, the code continues merrily along its way until I get a 'null reference' error which I'm trying to avoid via Force Termination().This is caused by the user cancelling DialogB, a selection process to get a database (SQL) instance.[code]

Embed A Windows Form Application?

Mar 31, 2011

Well it's been two weeks since I've been trying to figure out how to convert a windows form application into asp.net web application but I guess it is not possible. So I want to try something else, embedding the windows form on my webpage.

Anyway, I design a windows form application in Visual Basic Express Edition and I want to embed onto my webpage whcih I designed in Dreamweaver. Does anyone know if it is possible to embed a windows form application in a web page that will run in a web browsers? Or where I can find some references, couldn't find in google searches?

Something similar to using javascript to embed objects on a web page.
