If you can already see the directory the files are in using standard Directory and File methods, why would you need to open a socket to the server to read the file?? You just open the file like you would any other local file on your machine.

Thanks Dave! I realized shortly after I posted this that it would appear as a simple drive on the networked machine. I didn;t have all the details before I posted but I thank you all the same.

How can I list a directory into a listBox and view its content OnClick inside the listBox?

Hi,
Can anyone guide me on a simple code to load a directory into a listBox and When I click a file it loads in its respective format.

I look all over the place, what I found is confusing and not compatable with visual studio 2005

thanks,

Look at the Directory.GetFiles() method. It'll return an array of filenames in the directory you specify. You can then add those names to the ListBox.

When the user clicks the file, you can use the Process class to launch the file. You don't need to know what application opens the file.

I did something like this below but i cannot get it to list the file in a listbox:

Dim Files As String()
Dim FileName As String
Files = directory.Getfiles("C:\", "*")

for each fileName in Files

listbox.text=FileName
next

the file will not list in the listBox

thanks again

Hi,

every Control has a Text property; for simple Controls, such as a Label, that sets the content.
For listing Controls (ListBox, ListView, ...) the content is a collection, often called Items.

If all this is new to you, I strongly suggest you pick up a book on Windows programming, then use MSDN or google to refresh your memory on specific details.

You are right but listbox.items is READONLY property..

so how can i achieve my goal here?

You didn't happen to notice that that ReadOnly Items property has an Add method, did you? Microsoft hides that kind of stuff in the documentation on the ListBox control[^].

I know, and I'm glad it is. I don't want to replace the collection by another one; I often want to operate on the collection though.

You have 'javascript' and 'asp.net' in your subject yet you decided the 'visual basic' forum was the place to post your question.

How many lines would this read in one iteration of the loop?
Are you sure the number of lines in the file is a multiple of that number??

BTW: in a HashTable all keys must be non-null and different; can you guarantee they will all be different?

Since you haven't show us the code that's throwing the error, this list[^] of Google search results is the best you're going to get right now.

...and that error message has nothing to do with changing the computer name of a PC.

Problem in IF statement

vijay24821-Oct-09 23:04

Hi all,

I'm working on a vb.net application that has many functions and sub's.
In one of the sub, I check the values in a field with a list from database and with another text file.

The condition goes as follows:
If a field value in text file 1, not found in list from database, then I will check if the field value in text file 1 exist in text file 2.
If found both the fields same in both the text file, I perform an action,
If found that the first field is same and second field not same, I perform another another action,
If found that both the fields are not the same, I perform another action.

Thanks in Advance.

Your code is obviously convoluted and messy.

If doc.enfant is not equal to cad.enfant, and doc.draw DOES equal cad.draw, nothing will happen. So, have you stepped through the code to see what's going wrong ?

Well, it's obviously impossible to work that out, based on the code you have provided.

If you simplified the code, it would be easier to read. As it stands, you need to check each line carefully, instead of checking blocks that break up the logic.

Hi,

IMO your complex IF stuff is equivalent to:

If cad.EnfantInM1 Or cad.IsStdComponent Then
    If doc.enfant = cad.enfant Then
        WriteCreateToExcelDoc(cad, doc, exlLst)
    ElseIf doc.draw <> cad.draw Then
        WriteCreateToExcel00(cad, exlLst)
        WriteCreateToExcelND(cad, exlLst)
    EndIf
Endif

which may or may not be what you want.
