In VB.Net is there a simple way of displaying all the files in a selected folder depending on a criteria and how would you display via a message box the file selected.
Is it something like as follows. Getting mixed up with VB 6 and .net. I have a dirlistbox, drivelistbox and a filelistbox. I can get a connection between drive and folder but what is the syntax for the files. Feeling stupid here.
Private Sub drvLoc_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles drvLoc.SelectedIndexChanged
dirLoc.Path = drvLoc.Drive
End Sub

You would want to use a ComboBox and a ListBox for this. Like so:
Private Sub DriveComboBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DriveComboBox.SelectedIndexChanged
FolderListBox.Items.Clear()
For Each Dir As String In My.Computer.FileSystem.GetDirectories(DriveComboBox.SelectedItem, FileIO.SearchOption.SearchTopLevelOnly)
FolderListBox.Items.Add(Dir)
Next
End Sub
Private Sub FolderListBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FolderListBox.SelectedIndexChanged
FileListBox.Items.Clear()
For Each File As String In My.Computer.FileSystem.GetFiles(FolderListBox.SelectedItem, FileIO.SearchOption.SearchTopLevelOnly)
FileListBox.Items.Add(File)
Next
End Sub
Private Sub FileListBox_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileListBox.SelectedIndexChanged
MsgBox(FileListBox.SelectedItem)
End Sub
The DriveListBox, DirListBox and the FileListBox are not what you would want to use for this. Microsoft doesn't even offer support for these controls anymore. Plus, ListBoxes are a lot more customizable.
Hope this helps.

Forgot to mebtion I am using visual studio 2003 and the name my and FileIO does not work.

Well, I can't really help much with anything in VS2003, but you could go ahead and use a Drive, Directory and File ListBox (since you are using an older version of VS).
So, try this:
Private Sub DriveListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DriveListBox1.SelectedIndexChanged
DirListBox1.Path = DriveListBox1.Drive
End Sub
Private Sub FolderListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DirListBox1.SelectedIndexChanged
FileListBox1.Path = DirListBox1.Path
End Sub
Private Sub FileListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileListBox1.SelectedIndexChanged
MsgBox(FileListBox1.SelectedItem)
End Sub
Hope this helps!

I have a form where the user can add inventory items. Some items they will have multiple of the same item. I want the user to be able to enter all the information for that item except for the serial number field. I want them to be able to enter ALL of the serial numbers for all of the items at once.
EXAMPLE: A dept. buys 10 bullet proof vests. They go to enter the vests into the system. They type in all the information (make, model, cost, description, etc.) when they get to the last one which is serial number they can click the ENTER MULTIPLE button and have a small form pop up with a control to enter all 10 of the serial numbers for all 10 of the bullet proof vests.
I just need to know what the best control to use would be and any other information on how to use that control to accomplish what I need. THank you guys for your input. I do appreciate it, as always.

How is your database set up ? It sounds like you need a table for item types, and one for individual items ( an item type ID and a serial number, at minimum ).

Sorry it took me so long to reply. I got wrapped up on something else...
What Im really asking here, is what would be the best control to accept multiple serial numbers from the user. Like how you would enter a combo box's items in vb.net in the designer. You click on items in the property window and a rich text box comes up and you enter each combobox item each on a different line. Something like this. I guess I could do it like that, im just asking to see if you or anyone else can think of a better way to do it, and how... My database isnt built yet. I am writing the front-end first and then the back-end(SQL)...
Thanks for your help...

OK, I'd imagine your two options are to have a table to which a serial number is added in each row ( so, a combo box ), or, the way I see it mostly done, is a textbox and the serial numbers are semi colon delimited.

you can always use in case the object have it the dispose method or simply use somthing like this
if not objinfo is nothing then objinfo = nothing

Why do you check the value of the reference before setting it? It doesn't matter what the value is before, as it doesn't have to reference an object in order for you to be able to set it to Nothing. Just set it:
objinfo = Nothing

Hello Everybody,
Im learning web application with vb 2005 and I got some question, really I need your help

My question is why is table(0) ? and If I create more than one one table then how do the dsReport will find the table?
2. Is their anyway I can pass a HyperLink from the report?
Let me tell what Im doing................
I got the top 10 Customer basic information in the report, When I will click CustomerID or CustomerName then another page will be load where I can see the whole details also I would like to put a Button (CustomerActivity) when I will click the button then I would like to see about his transaction like how many times, how much................... what he has done so far.
Top 10 Customer --> One Customer whole details --> One Customer Activity
Also could you please tell me if I would like to pull data from web server then do I need to change..... the following
ReportViewer.LocalReport.ReportPath= Server.MapPath(" Name.rdlc")
or
Just change the DataAccess path ( Localhost to Server ............)
On the other hand, I viewed data in a GridView where I created some property for the table and connect the class file with the gridview.
Can I connect the Class (All Property (Like a Table)) with Report?
Im using VS 2005 Report and ReportViewer, I dont want to use Crystal Report.
Please help me......

Hi,
I'd like to know how i can print an image at it's real size.
I know how to print an image at full paper format, but how can i print an image at real format? (Source code pl0x)

Well, you realise if you print at 'real format', you'll get a tiny image, as most printers are at least 300 dpi ( so a 300x300 bitmap will be 1 inch square )

Hi All,
I was wondering if it's possible to make a form pop up in a specific area of the window?
For example if a button is pressed that calls form2, can I get form2 to pop up in a certain area of the window.
Thanks in advance

just add this line to form load method
Me.DesktopLocation = p
where p is a point.
|
|
|
|
|
how do I specify the point?
for example I want it to be in 559, 546 but when i do
Me.DesktopLocation = 559,546 it doesnt work (doesnt work when it's in brackets either).
Thanks
Jaidev

here you go...try this
Dim loc As New System.Drawing.Point
loc.X = 559
loc.Y = 546
Me.DesktopLocation() = loc
|
|
|
|
|
You have to declare a New Point. Like this:
<br />
Dim Place As New Point(200, 200)<br />
DesktopLocation = Place<br />
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

Hi ALL!
I wrote a very small app which reads out the cell values in excel and "Sendkey"s them to another application. I would firstly Send an 'alt tab' to set focus on the receiving application. Then basically flush all of the cell values.
E.g. of code used:
Application.Sendkeys "%{tab}", True
Application.Sendkeys ActiveCell.Value, True
Now, the problem is that it used to work perfectly on my old slow ass donkey machine. I recently got a newer, slicker machine and it just doesnt write the values to the application. It 'alt tabs' but just doesnt write them.
Any suggestions?
I will consider looking into AppActivate instead of 'alt tab'.
Thanks Peeps!

I have discovered that Excel 2003 likes to choose when to send the alt key (%).
If I edit the code and save it, then run it. it works fine.
If I open the xls file and just run it, it does not work.
Please can anyone tell me how to get excel to send the alt key every time?
I have tried "Application.Sendkeys" and "Sendkeys".
Thank You
