Open File Dialog Not Showing Network Locations
Jun 3, 2009I am doing setup project in VS 2008. I used custom action to select file from local drives. On the button click of custom action form, I am launching Open file dialog as ofdGetNetPath.ShowDialog When I run the setup on Vista, and click the button to open the openFileDialog, it hanged, form becomes non responsive and I have to cancel the setup.
on debugging I got following error "Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your main function has STAThreadAttribute marked in it. This exception is only raised if a debugger is attached to the process."
so I used the following code:
Dim ofdThread As Thread ofdThread = New Thread(New ThreadStart(AddressOf ShowOpenFileDialog)) ofdThread.SetApartmentState(ApartmentState.STA) ofdThread.Start() Private Sub ShowOpenFileDialog() Me.ofdGetNetPath.ShowDialog() End Sub
now on button click, OpenFileDialog is shown but it is not showing Mapped drive or Network location... what should I need to do to show the mapped drive or network locations?

Aug 18, 2009Here is my idea so far: I have a bunch of computers connected in a local network. One of them is a MySQL server, one will have a vb.NET program wich will act as a "second server" and the rest will be different clients. What I want to do is that the "second server" will send out some kind of message or network package to some of the clients in the network, and they will execute a code based on what message it is, or what kind of package it is. I'll give you a simple example:

Nov 18, 2011I have a .NET 2.0 *.dll that calls My.Computer.Network.Ping(). The *.dll is then run out of an *.exe via AppDomain.CreateDomain() and Invoke(). The problem is that this works just fine under Windows XP but under Windows 7, I get an exception saying that no network connection is available. I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

.net - Using A FileStream On A Network When The Network Drops?
Mar 26, 2012I am writing some code as part of a framework for opening a file.The file is of custom type and should not be opened by more than one instance of my application. To stop multiple file opening I use a filestream to create a lock file and then keep said filestream open. This seems to work in preventing another instance of my application from opening the file ( as it will fail in recreating the lock stream in the files open code ) but if the file is on a network share and the network drops then the original application also can not access the file any more.The code to get the lock stream is as follows:
Try
' We need to keep this stream alive to prevent other applications gaining access to the lock
mLockStream = New FileStream(mLockPath, FileMode.CreateNew, FileAccess.Write, FileShare.None)[code]....
In this I create the lock stream the first time round and then if another application tries to create it, it throws an exception and stops them from getting any further. This is kind of how it needs to work, unfortunately as I said, if this is done across a network and then the network connection is dropped for some reason then I can not delete the lock stream as I get an IOException telling me a process cannot access the file as it is open in another process ( which shouldn't be happening I don't think).

Jun 2, 2011It's been a while since I've had to add a CheckBoxCol to a DataGridView, so I copied and pasted the code directly from the example shown in the MSDN library page here: [url]Anyway -- the column is added as expected however, there is no checkbox! (see the column "Accept" in the image I've posted). I was hoping I am missing something easy/obvious, and I've had success with this before in other apps so this is becoming frustrating.DGV's Datasource is set to a datatable found in a Dataset. Everything loads just fine. No errors.

View 10 RepliesFlowLayoutPanel Not Showing All Contents?
Jan 26, 2012I have been dynamically adding user controls to my panel. This user control has a height of 105. If I have my FlowLayoutPanelwidth to only show 1 "column" of controls, it will only display 296 of them. The rest of the controls are grayed out at the bottom of the flowlayoutpanel. If I widen the flp to allow 2 "columns" of controls, I can see 592 of them, with the remainder grayed out at the bottom. I have gone in and resized the user control to make it shorter in height, which works in some respects (i.e. it works when I have two columns, but not just 1), and can go forward with this work-around.
So, I guess my question is, why does the FlowLayoutPanel behave in this fashion? It seems (based on what I saw) that there is a limit to how much data the FLP will show at one time.

Animate The Showing Of A Form?
