The code is suposed to go through all the computer names in a list box and ping them.
I am used to C like languages such as C#. I added a list box with a list of names. In the code behind I added the below code. When I run the code I am getting the MessageBox but it will state "UserName favorite color is " but does not show the color. I thought it might be misspelled or non-matching names but this is not the issue due to the names being correct.

The way we get my.computer.name, can we also get the name of all computers on a network?
View 1 RepliesI am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?
winform not webpage is it possible.i need to ping ip addresess from a list of items that are in an xml file and displayed in a datarepeater.and then return the response to a non-databound textbox inside each "record" in the datarepeater.i can ping fine if i hard code ip adresses into the program, but haven't been able to access anything inside the datarepeater.
just as a test i set a messagebox to give me the text of a label i have inside the repeater, even though on screen the label says server02 the message box shows the label.text as being "label15".

I tried the Ping() call out of a small console application under Windows 7 and it works just fine.

View 2 Replieshow to list names from a file, as you enter (spell) the name. eg if you enter 'b' all 'b' names will appear. If you next enter 'e' then all 'be' names will appear. repeating this until the last letters are entered. eg 'bell' will show all names starting with 'bell'. You can then select from the list the correct name?
View 2 RepliesSo in my Textbox I have a list of (folder) names, such as:
Folder1
Folder2
Folder3
I want to compare THAT list to another folder somewhere in someones documents (no specific folder). So let's say we compare it to the 'Arts' folder, which contain these folders inside:
Folder1
Folder2
I want to put all of those folder names in the Art folder into a list. And then I want to compare the folder names in my Textbox to the folder names in the Arts folder, and Folder3 is missing in the Art folder, so I want the textbox to contain:
Folder3
...to tell you that you are missing Folder 3 in your Art folder.
I am using VB.NET in VS 2008 Professional. I wish to have my user select the server where the SQL Database resides. I can get a list of the SQL databases, but I am stuck on how to display the servers currently available to the user? I want to add the list of servers available into a list box and have them select the server.
The thing I am trying to duplicate is the drop down list of server names when you are doing an Add Connection from the Data Connections node of the Server Explorer.
For my assignment i need to list all the objects and their names. Surely i can get a list because typing out 150 names seems a bit ?
View 7 RepliesI am trying to find out if an instance of an application (not vb.net) is already running - because I will want to start it but I don't want to start it if it is already running. I have found a solution to check if a process is running:
Dim proc As Integer = Process.GetProcessesByName(ProcessName).GetUpperBound(0) + 1
and return True if >=1 (or just the process number). My problem is, this is a third-party application, and its process name is not just a name but it contains a version number (which I may not know at run time), and it also seems to add a *32 (so probably a *64 if it is installed in x64 ?).
I need to get a list of running processes, by name, and test if "processname" is a substring of the name.
But I haven't been successful in getting a list of names, only process id's.
I have a table in a Access Database that I'm loading into a VB.NET program and I want a way to get the name of each of the columns into a list of Strings. Googling has shown that this is much easier with a SQL database, but that doing so in Access is much more difficult. I came across this question Is there a query that will return all of the column names in a Microsoft Access table? Which gives a way to do it, but when I try the code it just populates my list with a bunch of "System.Collections.Generic.List'1[System.String]"
This is my adapted code.

I have a list of File_Name, File_Date.
I need to check this list sometimes against a file name and sometimes against both a filename and a file date.
I've been doing a for each loop and checking each value, I've tried a hash table keyed on file_name which is much faster, however I also need to check to see if the file_name and File_Date combination exist.
Is it possible to have a list that I can do a quick search on using either the filename or both the filename and filedate.
What I am trying to do is search through a list of file names looking for files with the same File name the following code is run from a button on the form The code seem to work ok up to the Array the line marked with ### is the line that the code stops at run time.
