Windows :: Best Display / Editing Of Subcategories?
Jul 8, 2009
I've got a categories table, and sub-category tables 3 levels deep (in the database they're called Categories, SubCategories, SubSubCategories, and SubSubSubCategories).On the presentation side, I am curious what the best way is to manage those. The categories form a tree/hierarchy structure, so a tree control of some kind sounds useful. Drag-and-drop functionality would be nice. This can be done in a VB.NET 3.5 web application (preferred) or VB.NET Windows application.

I have a datagridview and in the _CellValidating event I am checking a cell to make sure it is filled in. If it is not, I want to stop editing, display a msgbox, and highlight the particular cell. Here is my code :
If e.ColumnIndex = 2 Then
If e.FormattedValue = "" Then
If Me.dgvFish.IsCurrentCellDirty Then
MsgBox("Sample Number is a required field.")
[code]....
For some reason, I can't get the cell's backcolor to be filled in.

So I was wondering if anyone has done their own Forms (inheriting windows form and editing the properties) and if so, what your finished result was. And, if you are willing to post a screenshot of your finished result, that would be sweet! Trying to get some ideas of what can be accomplished with customizing the default form.

Whenever a person adjusts how big they want there display, it will distort my application, it will make images overlap and will make text bigger.
Is there some code I can do to tell my program to ignore the size set by the display on windows?

I'm using VB 2010, accessing a MS Access database. I have constructed a simple Windows Form returning data from the db, one field of which has a reference to an image I'm trying to display together with the data from each individual record.
I have a field with a product number, that matches the jpg file name (ie, the product number 5505 matches an image that I want to display, namely 5505.jpg). I've even created a new field in the db called 'Image', that contains the full name 5505.jpg.
So, I've connected to the db with an OleDbAdapter, and all the data fields are displayed via bound textboxes. I've been able to display a single 'set' image with a PictureBox, but I'm not sure how the make the connection between the returned data (txtSearchImage which is, say, '5505.jpg'), and getting the Windows Form to display this.
Am I on the right track using a PictureBox? I've tried binding this via the PictureBox properties to the relevant data field, but (obviously) it doesn't make the connection to the image file on my hard drive.
Here's my code so far:
Public Class Form1
Private Sub btnSearchKits_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchKits.Click
' The following line passes the value the user enter for state

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

Just like an array in a group box or a frame as i used in vb6.
If there are 5 customers details then when i load the form it will add (PictureBox, Label and a listbox) for each customer dynamically and display them with their information. Moreover, if i add 6th Customer information in the database then next time i load the form it should display his/her information as well. I did this in VB6 sometimes back but need a start to do in .net
Private Sub LoadCustomerInformation()
Dim Qry As String
Dim RS As New Recordset

I need to display 3 columns and a varying amount of rows (typically around 50) in a windows form, kinda like excel. The data will likely be longer than the window, so a scroll bar will have to come into play somewhere.

I've been working of a Visual Basic Windows Form in Visual Studio 2010 as my first little VB project. It's a form which runs a stored procedure on SQL. I have this all working, however, the stored procedure has a PRINT statement execute if a duplicate is found and stops. What I'd like to do is have this PRINT statement display on the Windows form MessageLabel (label) or have a "successful" message displayed if there is no SQL print statement.

In the Windows control panel you can adjust the Display properties for which text size to use between the default value which is the smallest size text and 2 larger sizes. How can you get which text size the Display properties are set to for one's computer through Visual Basic code?

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

I have a windows form where I want the time to constantly be updated. Right now it will take the current time from when the program was started.
For example, if I started the program at 4:30:29 PM that is what it will show the whole time the program runs.I need it to constantly be updated as the seconds tick by. So, If I started the program at 4:30:29 PM and ran it for exactly 5 minutes, the time displayed then should be 4:35:29 PM.The data being taken in and saved needs a time associated with it and the end user also need to know the current time as the program is ran in full-screen.

I have a procedure that loops through the directories/subdirectories on a file server and sets the permissions. Procedure is called on a button click of a form.
I need to display on the form which directory is being processed. Similar to if we use the Debug.writeline which writes to the output in Visual Studio. I tried using a ListBox but it only displays the last one and only displays the last one once processing is done. I want to be able to display each directory name as it is being processed.
Psuedo code as follows:
For each dir in L drive
setPermissions(dir)
'display in ListBox dir name
lstProgress.Items.Add(dir.Name)

I have a vb.net application that uses ShowDialog() to open child screens.
Long story short, I had issues with focusing the control if I opened IE on top of my program without minimizing the program. Once I reactivated my program and closed a child window, IE would show again instead of my program. I fixed this by setting the owner of my form.
Now I have another issue. After setting the owner, the parent (text) name of my form is now being shown at the top of the application when a child screen is open instead of the parent name. How can I fix this to show only the child's text form name when a child screen is open?

Is there a way to automatically resize a windows form to fit a smaller display? I created a program on a computer with a 12" display, everything works fine. However, when I load the same program on a computer with a 8" display, I am not able to view all the contents on the windows form. Is there a way to correct this without manually resizing all the contents on the form?
