I have a windows user control that reads events from the application log of a remote server. I can read in the information alright, and it appears to happen very quickly, however the thread hangs up for about 30 seconds afterwards and keeps my application from displaying the log.
I am afraid that this is probably caused by my lack of experience in dealing with threads, but I cannot be certain. I am definitely open to any suggestions with my threading here.
The easiest way to see what I am referring to is when the btnClear_click event handler is called. After jumping through the threading worm hole, it goes to the LoadFilteredEvent method. The results load fairly quickly from the ManagementObjectSearcher, but it hangs up for 30 to 60 seconds on the next statement.

I would like to know if there is a way to see how long a program runs. I have one that takes a very long time to run, which is not the problem. I start it and go to bed or leave for the day. When I come back it has finished. I do know it takes hours. Is there a way to find out how long it does take to run give or take a couple of minutes?

Gives this error: Value of type 'System.Collections.Generic.KeyValuePair(Of String, Long)' cannot be converted to 'System.Collections.DictionaryEntry'.
In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:

It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.

I'm in high doubt of this actually exsisting but still want to check, is there a way so that whether the VB form has focus or not it can still read the keys being typed? I am using winamp and i type something and the form picks it up, so when i type something like ctrl+"exit" the application closes. the thread should be running as the form is Always on top, however for obvious reasons the form does not have focus, so something like keyPressEventArgs won't have an effect, is there any way that you can catch the keys in a global perspective.

View 2 RepliesI am trying to read in and eventually manipulate an 'XML-type' file. I have picked up a hobby called 'Geocaching', some people probably have heard of it, where you use gps coords to locate items placed by other people. Well, you can download the gps coors within data files from the website,'Geocaching.com' and these files are in a XML format.
There are a lot of programs out there that people offer, some are better than others, but I am not happy with the results. So, I am trying to see how I can use these files myself and create my own program to use the data in a way that I want to use it.
I have tried to use Linq, XMLdocument, XMLreader and probably a couple of others over the past week. I have had marginal sucess with each of these methods, but nothing great and I owe that to my lack of knowledge.
I eventually hope to add the data to a Access db that I am using and manipulate the info from the db.
I am attaching a sample of one of the downloaded files and if someone would have the patience to help me work my way through it, p.s. The file typically ends with '.gpx', but since its an xml and thats what the system recognizes, I added the extension in order to upload the sample file.

My program reads a 3rd party .txt file using OleDb and reads the file into a datatable. It's overall working fine except a user will occasionally have a problem reading a file. At this point.
Line that gets hung up
Try

Dim dasold As New OleDbDataAdapter(comm1)
dasold.Fill(dtsold)

It can not retrieve a date for one of the fields, then gives error and does not get dates for each records after the one it gets hung up on but the date is in the file. If I open the file in excel and play with the column sizing, for instance just autoformat column width then it read the date and will work fine. I have looked at the file in notepad and cant see anything wrong in particular on the record it gets hung up on. I have no control over the .txt file since it comes form a 3rd party.

I have created football (American) play creator. When the user is satisfied with a play he has created it is saved it as a file with a .play extension. What I want to do is to cycle through all the files in a folder (probably named after the team), and place each one that has the .play extension into a CList (of ClPlay) collection.I have been able to successfully load one play at a time by using this code...
Dim fs As Stream = New FileStream(diaOpenPlay.FileName, FileMode.Open)
Dim bf As Runtime.Serialization.Formatters.Binary.BinaryFormatter = New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim Play As CLPlay
Play = CType(bf.Deserialize(fs), CLPlay)
...but that was when a specific play was selected from a load dialog box. This time I want to load all the plays in a folder and store it in a collection, and I'm not sure how to modify the above code to do that.
