Is there any method to do batch update winForm in VB 2010
Using Microsoft Access2007 as database, VB 2010 WinForm (DataGridview + Textbox)
There are a lot of record need to be Updated, It is very efficient if that data is just going through Batch Update, meaning just one click will update all the data rather than click one by one.
Any Demo or code showing how to do this Batch Update (VB.net).

I have a winforms app with multiple GUI threads. I want them to be able to access each other's thread objects without having to keep track of that information separately.Is there a function in .NET that I can feed a winforms control or window object, and get back the thread? Or a function in the API I can pinvoke for the threadID?
Edit For those of you who for some reason believed my italicized text, congratualations, you're hired!! Here is the problem: "App is crashing in the wild by locking up totally, that is, it stop responding. Very intermittent, and trying to debug it, it seems to never happen."
So what do do? Install an option in the program that the user can activate under our direction, whereby from another GUI thread in the same app, do a thread.abort on the main GUI thread, then we can look at the call stack in the error log. Viola, found an impossible to debug error in less than a day. (Stop now, it had nothing to do with abusing multithreading:-)
I'll admit I almost didn't ask this, the reason I did was I could see an object reference to the main form, but there wasn't any for its thread. I'm giving Chris Shain the answer a/c it is a quick way, unfortunately when the thread is hanging, I wouldn't be able to do an invoke (it would hang too). A little more digging revealed the GetWindowThreadProcessId API call. But it's an unmanaged thread ID, apparently there are complications turning that into a managed thread ID.
So I bit the bullet and put in a global reference to the main UI thread. Would have posted it to begin with, but hadn't written it yet.In main public module/static class:
ok so i dynamically create a wsf for running an automated telnet session that works great!!(finally!!) but auto executing the script from my code is proving difficult for whatever reason.
I have tried:
Shell("C:shutoffscript.wsf") this produces this result.
also tried setting a bat file that launches the script and launching it as well using shell every time I launch it I get an error in the script that works just fine executed outside my code.
using outfile As New StreamWriter("c:" & "shutoffscript.wsf") outfile.Write(sb.ToString()) End Using MsgBox("Script built press ok to execute") Shell("C:shutoffscript.wsf")
I think this has to be some sort of permissions error right? Since both errors tend to not be able to find the file. Just not sure how to fix it.

Done quite a bit of looking but not finding what i need. From a win form i'd like to open up a web browser passing in a url. But i need to provide authentication while doing this. I tried just using a system.diagnostics.process.start("http://userid:pw@site") but that does not work. Was hoping someone could lend a hand.

so is there anything else that can be done to get IE to work.. cause i'm thinking that would allow the above code to work as well.
There is alot of "search-hits" for the BASS.net Lib, but there seems to be non documentation for how to do this on the [URL] page. My problem is: I want to be able to play a .XM file in my Winform. I'm using VS 2008, .NET 2.0 on a 64-bit computer. Does anyone have any experience with this?

I am using vb.net / Winform 2010.I am looking for a free (or very cheap) alternative to the DataGridView, one that looks more like what I see on ads for XTraGrid. Something that will multiple lines per records, and for lines to be rolled up, and expanded by clicking, etc.
I've been profiling a WinForm's application using ".NET Memory Profiler".I can't quite seem to understand how my application is growing to 1GB, then 2GB, then 3GB of usage - according to windows task manager.
The private bytes using that tool, and "Total Bytes in All Heaps" shows only as 70MB or so. At the top of my list of instances hanging around, they are mostly String, or WeakReferences to lots of little objects.
All the application is doing is showing a form that loads data from a database. I repeat the show/dispose cycle of the form about 100 times and the growth is continuous.I've tried about 3 memory profiling tools now and none of them are showing me where this enormous amount of memory consumption is coming from.
The application is written using VB in VS 2008 with .NET 3.5 I have a table in SQL Server that represents Invoices and in the table is a field named "Paid" which is define as CHAR 1 with values of "Y" or "N". Nulls are not allowed.I have two Bound Windows forms to manage the Invoice data, one with a DataGridView and the other a Detail Form. Both use the CheckBox control for the Paid field.
In the DataGridView I can define values for the TrueValue and FalseValue and the Database is updated correctly.I can not find anything like this for the CheckBox control on the detail form.Am I missing something? It seems like if it is one it would be in the other for the same control.handle a CheckBox on a Detail form? CheckedChanged?, NewClass for the CheckBox (which I have not done before)? Other?
im using membership of asp.net to manage user and roles in my vb.net winform application when logged in i wanna get the current user in a specific form
i use that code
nom = TextBox1.Text Dim user As MembershipUser = Membership.GetUser(nom) Dim identity As New GenericIdentity(user.UserName)
I don't find a CanGrow property on the Textbox control. This is common in some other controls, and what it does is expand the control to acomodate more data. Anyway to get this feature in the TextBox?
