Detect And Show If A File Delete Failed?
Mar 6, 2012
How would I detect and show if a file copy failed?
I am using the following to do a file delete: System.IO.File.Delete("C:TestTreeTestLaunch.xml")
The problem is that I do not get any error if the delete fails. My main worry is if the file I am trying to delete is marked read only and the app can not delete it then the user will not know that the delete failed
Also - Any way to see if a copy failed? - I am using the following to do a file copy: System.IO.File.Copy(C: emplate.xml", "C:TestLaunch.xml")
put detect and put a message if this fails?

Is there a way to detect if a My.Computer.FileSystem.CopyDirectory() has failed? It seems that if it fails the copy (i.e., not even space on the destination drive), it just quits and doesn't seem to throw me an error? I already have it in a Try/Catch block, but I'm using that to see if the source directory exists, I'm guessing I should use

I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

I created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?

Whenever I open any VBP file in Visual Basic 6.0, I get Method '~' of object '~' failed error. After that project compiles without any error i.e I can create either EXE or DLL without any error. Originally, all files are Visual Basic 5.0 vbp files and we are converting Visual Basic 5.0 to Visual Basic 6.0. We will be converting to .Net after converting to VB6. Application uses microsoft access as data storage.I am running Windows XP on my machine. I have got .Net 3.5, Jet 3.5 Sp3, Microsoft Office 2003 installed on my machine.

I am trying to read from a text file called: "NameList1.txt". It has four lines and two variables seperated by a ",".
The following is my code:
FileOpen(fn, NameFile, OpenMode.Input)
Do While
Not EOF(fn)
Input(fn, a, b)
txbFirstData.Text = a
txbScndData.Text = b
Loop
"End of code"
fn is the freefile number and "NameFile" the the path and filename.
I get the following error:
Overload resolutionfailed because no accesible 'Input' accepts this number of arguments.

nutty VS2005 error. I know I have an error in my dataset file (XSD file), but none of the errors listed after this warning message truly points to the source of the problem. In the past, when my dataset had only a few tables, it was easy to find the error. Now I have 50+ tables. I'm not sure where to start.

I'm using Visual Studio 2005 Team System For Software Developers. When I try to add a new DataSet to any kind of project, I cannot get to the visual DataSet designer. Rather, I get the following error (all the time no matter what the type project actually is - Windows app, Web site, etc.): The custom tool 'MSDataSetGenerator' failed. Unable to convert input xml file content to a DataSet. Data at the root level is invalid. Line 1, position 1.

how I could make an application in visual basic 2008/vb2005 that detects when a new file is downloaded. One of my old time friends created the same app with visual basic 2008. It notifys you when your attempting to download a file. For e.g: I try to download "aim6.exe"
it will show a message: "C:UsersMATTST~1AppDataLocalTempsXx0Fd31.exe.part is attempting to be downloaded"
I think it uses a file system watcher.
