I have 3 lists in my form.When 1 list is clicked, I want to drop the selection in the other 2 lists.
Private Sub lstPlaylist_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstPlaylist.SelectedIndexChanged
lstArtist.ClearSelected()[code]....
This is my current code. When I click on lstPlaylist, it drops the selection for all lists.
the problem - i have a list box, which i use to display info (obvs) but when i click on one of items in the list when debugging, i wondered if there was a way to store which one was selected in a variable?
dim selected as string
selected = 'vb variable for a click?
How would I display list items from multiple selection listbox in order they are clicked?
View 4 RepliesI'm looking at modifying an application we use in the office, the program links to the phone system and allows us to cross caller ID with our database and dial numbers from the database.What I'm trying to work out is how to add a selection to the generic windows right click menu. ie I want to mark a phone number in say ie or word and 'right click' and be able to click 'dial' from the menu. What are these menu's called and can i access its components from VB?
View 2 RepliesWhen we left click a grid cell, or list item, it highlights. Left click outside it and the selection jumps to the new place.
I can RIGHT click anywhere in the grid without disturbing an existing highlight, but I want it to work more like windows explorer would in terms of file selection..
i.e. if I right click inside the range, the range stays, if I right click outside the range, the range moves to a new single cell that I just right flicked.
Try it now on this page. Select some text, right click on the selection and it stays. Right click outside the selection and it goes. In datagrid (for example), the selection can only be modified with a left click.
How can we change this so the selection behaviour of a datagrid/list is more like this text pane?
On a related note. If I left click in a textbox I can drag a selection out. If i wanted to right click and drag the selection out, would it be the same process? (It's for a custom string manipulation picker control..)
I have written a application that has a TCP client and server to connect to a PLC. The Client works perfectly but it looks like the server drops out all the time. What happens is when I first start the connection it will update without any problems but after about 1min of no transfer the PLC can no longer send data to the application. Neither system gives an error and the PLC shows that it is transmitting the data but nothing comes through on the application side of things. I have tried to put in heartbeat to see if that would stop the drop out but to no avail.[code]
View 10 RepliesI have two lists. One list is a list of names, the other list is a list of how many times each name is found in the first list noted in the database
so...
Nick
John
Jim
Jack
is the firs tlist
10
13
13
2
is the second list. Nick had 10, john 13 and so on.I want to sort the second list from large to small, but have the index for the first list still linked to the correct amount of calls.i do it this way so I can
for x = 0 to num_of_names

I have this app written in VB.Net with winforms that shows some stats and pictures on a bigscreen monitor.I also monitor the memory usage of sad app by using this. Process.WorkingSet64
I know windows does not always report the correct usage but I just wanted to know if I didn't have any little memory leaks which I had but are solved now. But the first week the memory usage was around 100MB and the second week the memory usage showed around 50MB.
So why did it all of a sudden drop while still running the exact same code?I can hardly imagine that the garbage collector kicked in this late since the app refreshes every 10 seconds and it has ample time in between those periods to do it's thing.Or perhaps there is just better way to get memory usage for a process that is more reliable.
I've been using some code which I found on the net, and have noticed that the first byte is never recieved. Annoyingly, this contains the MAC addresses, which is the bit I want. Below is the relevant snippits:

I can't see anything in the method list that lets you know when a connection drops (and since it's constantly checking, it seems that could have been in there, to raise a flag when it can't find the connection anymore...no?). Is there a way to know if the network connection drops? Is there a way to reconnect it? Is it just a matter of turning EnableRaisingEvents() off and back on to re-establish the link to the network share?

I 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).
I would like to loop through two lists using a For each loop.
dim data as list(of pointpairlist)
For each recLine in records
For Each chan In recLine.channels and d in data
d.add( func(chan) )
Next
next
Note: each record line has one sample from each channel recorded. i.e. each record line is a slice of a 32 sensor recordings. I want to build up a x,y list of data points for each channel (the x axis is common to all channels). Is there some way to do it similar to what I have above (avoiding indexing variables).
I'm trying to populate one list from another. I would think this code should work, but at the end of the day I get a list of identical items.

I'm very new to programing and am having problems trying to perform some calculations with a list. I have read in an array into a list with a count attached to each item example: "xxxxxx(intcount)". What I'm trying to do it use two xxxxxx(intcount)'s at xxxxxx(intcount+5) and xxxxxx(intcount+25) and use these two variables to calculate yyyyyy(intcount) but it isn't working. I understand this may be a stupid question but could someone please point me in the right direction.

View 6 RepliesI have a method where I'm taking a generic object and using TypeOf to check what has been passed through. Now I would like to pass it a List(Of T) (T being anything) and no matter what T is I'd like to do the same thing to this list. I tried the following:
public sub foo(ByVal obj As Object)
if TypeOf obj Is List(Of Object) Then
'do stuff
end if
end sub
but this doesn't seem to work if I pass it List(Of String), say. I suppose that List(Of Object) and List(Of String) are being treated as different objects, but I thought that since String is an object, the comparision might work.
Now I realise that this is as ugly as sin and I'm better off overloading the method to take List(Of T) as its parameter, but I'm mostly asking out of curiosity: is there a way of comparing the types List(Of Object1) and List(Of Object2) and getting a positive result, since they are both just List(Of T)?

Right now I have a viewmodel that contains three lists of inputs; textboxinput, dropdownlistinput, and checkboxinput. Each of these lists is a list of input objects, which contain four values; paramenums, paramname, paramtype, and value. I am using these input lists to generate a variable number of fields on a form dependent on how many objects each list contains.
My current problem is that I'm not sure how to validate the variables in the list objects with fluent validation. I know how the behavior of each list should behave with regards to returning Nothing, but I don't know how to code that behavior with FluentValidation.
[Code]...
The thing I want to currently do is confirm that in every object in each of my lists, they all have a value attribute that isn't nothing. Can I do this by validating the input model? Right now, the code works at confirming that the list itself isn't null, but the objects in the list can still contain all null values. Is there a trivial way to do this? Alternatively, should I have set my code up differently?
