?????????? What kind of problem are you having? What you said amounts to "I want my component to run a script using msscript.ocx". Are you talking about adding scripting support to your application?

An exclusive lock is only placed when somebody has it open on the desktop. Multiple OleDb connections are ok, just no combination of desktop user and OleDb user.

If someone has the database open in Access it will be locked exclusive. Also, make sure your application is running under an account that has Read and Write rights to the folder where your database resides. If you don't have Write access, then your database will appear locked.

Yep! you sure can.
The main idea is to make a form, with the buttons 'Back', 'Next' and 'Cancel'
then pacing a frame array on that: Frame1(n) that all have their Visible property set to False.
each frame is presenting the face of a wisard step.
(the frames must all be of the same size and must overlap each other completely.
then simply in the click events of next and back buttons, try showing the propper frame (makeing it's visible property True and the Visible property of the previous Frame to False)

now try designing each step on it's own Frame!
so simple yeah?

(VB Wisard Manager helps you do the same thing in VB6 but the idea is still the same.)

dataset basic navigation / traversing

25-Oct-04 12:38

Hi, Please forgive me for the simplicity of the question, and the redundancy. I have searched the forum and believe my answer is out there amongst the multiple dataset question/responses, but I am such a newbie that I am having trouble putting together the information I need...Ok, enough, here's what I am trying to do:

I am making a call to a third party API that returns a dataset. I need find out if there are any rows returned, and if so pull out the data from a couple of the columns...

More specifically, I get the dataset. Each row contains many columns, the three I need to get are BuySell, ControlValue, and Price.

Can someone toss out to me the simple code for traversing through the dataset and pulling out the values from these columns.

Many Thanks -
Jennifer

Dim WithEvents cbeButton As Office.CommandBarButton
Dim cbcButton() As Office.CommandBarButton

Simple String Question

Hey

I need to trim 4 characters off the right hand side of my string and am having a little trouble doing so.

For example "Hello.doc" becomes "Hello"

I could use split at "." but this wont stay constant if there is a "." in the filename itself

Thanks for your time

Hey, Chris. You could try:

dim s1 as string = "Hello.doc";
dim s2 as string = Left(s1, Len(s1) - 4)

Or, if you're dealing with file/path names and want to extract portions of it (say just the filename, or just the extension, that sort of thing) have a look at the System.IO.Path class.

Hi, I might have the similar question too. I use an OpenFileDialog for user to select the file and they select TheFile.doc, How could I know that user select file extension with .doc? Can you help that? Because I want to check the 4 character from the right side.

data grid control in visual basic.net

Hi, I'm KUMARAN KALIDAS Smile | :)

First I would like thank to all the ppl behind the codeproject, coz it really help me in terms developing a .net application with various examples..thank you again..since i'm new developer for the .net environment.

I need a help, in order for me to use a datagrid control in my visual basic.net project. I would like to use datagrid as a data input screen rather than using it to display data.

How can use datagrid control as transaction input screen which contain validation as well.

I would appreciate if anyone could help to provide me with a sample source code..I hv search tru msdn for .net but the sample was almost for data display purpose only.

thank you guy's for code project

First of all you must consider the following:
are you using sql connection or an OleDbDataAdapterconnection.
The difference with the two is the coding and where the port is located.
I am thinking that you're on the MSAccess database which you will need to use the OleDbDataAdapterconnection for your project.

Using the MSAccess database you must first create a blank database through Access. Open your Access database, click on Blank Table, and click on the design view this will take you to the tables configuration. You will see a number of fields. In the Field Name you will input all your information about what you want to create in a datagrid. E.G. Addresses in the Field Name you will input "First Name, Last Name, Address, City, State, Zip Code, Telephone Number." For each field you will single click to select them then you will go down and validate your entry. Email me to give a good perspective of how to create the database and use the datagrid in vb.net.

Network drive in a TreeView

25-Oct-04 2:52

Can anybody tell me how to list a network drive in a TreeView?

I currently list my drives this way:

Dim driveList() As String<br />
driveList = System.Environment.GetLogicalDrives()<br />
treeDirStructure.BeginUpdate()<br />
Dim x As Integer<br />
For x = 0 To driveList.Length - 1<br />
    Dim tvn As New TreeNode<br />
    tvn.Text = driveList(x)<br />
    Select Case GetDriveType(driveList(x))<br />
        Case DRIVE_REMOVABLE<br />
            tvn.ImageIndex = 0<br />
            tvn.SelectedImageIndex = 0<br />
        Case DRIVE_FIXED<br />
            tvn.ImageIndex = 1<br />
            tvn.SelectedImageIndex = 1<br />
        Case DRIVE_CDROM<br />
            tvn.ImageIndex = 2<br />
            tvn.SelectedImageIndex = 2<br />
        Case Else<br />
            tvn.ImageIndex = 0<br />
            tvn.SelectedImageIndex = 0<br />
    End Select<br />
    treeDirStructure.Nodes.Add(tvn)<br />
Next x<br />
treeDirStructure.Nodes.Add("C:\Targets")<br />
treeDirStructure.EndUpdate()

..but I can’t figure out how to list a network drive or other things like ‘My Computer’.

Thanks.

Hi
In short, you can't. The languages aren't interchangeable, and the nearest you could get is to wrap your c++ routines into a dll that can be used from within VB.

Exporting VB.Net DLLs to VB6

24-Oct-04 18:46

I have a really big application running on vb6, it will take months to port it to .net
in the meanwhile i need to use some GDI+ capabilities (and some threading).
I wrote some DLLs that will do the job for the big applications, but i don't know how to export them to VB6,
When i'm trying to add the reference to the DLL, it gives me an error message that it cannot use that kind of DLL.

I thought of using OCXs instead, but i don't seem to find a way to create an OCX in VB.Net (i know i can do in c++/# but i have tons of code already written in VB.net and i'm on a tight schedule)

Can anyone help me out?
