Active Form In Windows Application?
Oct 7, 2009
I am developing a Windows Forms application. I have four forms which is inherited from Baseform in another project. In all four forms I am using a label to show some transaction count based on network status. I have implemented a thread which gets the active form of application and setting up the text. The code works fine if application screen is active. If I minimize and open any other application, I am getting an null error exception.
How do I get the active form of an application?
Private Sub StartThread()
pollThread =New Thread(AddressOf PollfileStatus)
pollThread.IsBackground =True
running =True
pollThread.Start()

I have a mdi application. When some childforms are open (but only one is active) and the user press a button, I want to know, what form is open, because depending on this, an event will fire up. I imagine this so: at first I determine the active form with a separate function. And then with a select case statement the event will be fired up. How can I make this?

I have a standard Visual Studio 2008 VB.Net WinForm application, running on Vista Business. One of the forms has a timer that passes Me.Handle to FlashWindowEx. This works as intended as long as none of the windows that belong to this application are the Foreground window. If this program is running and another application's window is the Foreground window, then it flashes as intended. If, however, any of this application's windows are the Foreground window, then it doesn't flash.

I have seen this happen before but am not sure how I resolved it in the past. On runtime the controls of my form change from the windows 7/vista format to an older version format as shown in the attached image.
How to display the controls in the format on the left (new windows format)

1.) run the application at start up
2.) no icon
3.) always in focas
4.) always runs in the background.
Here's the full code I have right now (working! whahoooo)

I have a VB.Net project that I am running from a local server and I need to use the credentials the user is currently logged in with to upload a file to a folder I create on a SharePoint site on the same domain. I can get it to upload if I specify the credentials but it will not work with system.net.credentialcache.defaultcredentials. It just gives me 3 empty strings and I get a 401 unauthorized error. I have seen a few threads that say you cannot use it with Windows Forms Applications. Is this true? Here is my code:

I am creating a program that interacts with another program and I would like to "inject" my program into this program as an MDI Child window. Is this even possible, and if so can it be done in VB.NET? What kind of pitfalls are associated with doing this?

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]

I am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.

I have just begun using Visual Studio to create a windows form application in visual basic. I have a chart on the form, and I would like to be able to right-click, copy the chart and then paste in,say, Microsoft word. At the moment I have created a contextmenustrip which appears when the user clicks on the chart, but I am unsure of the code necessary to actually copy the chart and hold it until pasted into a different application.

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.

What is the proper way to terminate a Windows Form application while it is just executing in the MyApplication_Startup routine?I have an application that looks for a database file upon startup. If it does not find it I prompt the user and ask if they wish to locate the file or not. If they choose not to locate the file I want to just terminate the application. Currently i just execute the "End" statement, but that does not seem like the proper way to terminate a program.

I downloaded Visual Basic 2005 Express Edition last night (the total download took about 3 hurs, but I digress). I started duing the little "Learn Visual Basic" tutorials. I've gotten to "Communicating with Your Program's User: The User Interface" and it asks me to open up a new project. Alright, fine, nothing I haven't done yet. But the problem is that it wants me to open the new project up in Windows Form Application.
