I have an app that I have made. The application generates 14million combinations of numbers and inserts them into an Access Database. As you can imagine, this takes AGES (whole night) to compute. Is it possible to make the same method call twice so instead of one combination being generated and inserted, two or more are?
View 5 RepliesI'm new to databasing. How do you make it so you can add an item to a database on a form, Then follow a link to another form which has the database on, then what you put in on the previous form will be there?
How's it done? Sorry - Haven't been using VB very long >.<
I am using the vb 2005 to create an application and I created a database from the vb by adding a new Item (Database). I want to know how can I make the id which is a number, to take an auto number and not to have to enter it with my insert statement. I know in oracle I use a sequence and in access I use Auto Number as a type for the field, I want something like this here.
View 2 RepliesHi how's it going. In the middle of coding a banking application for a project. Part of it involves mortgage interest repayments. Was wondering if there was any way of logging the time a new record was created and added to the database and then adding interest to the balance owed periodically every 30 days..

I am trying to create what I am sure is a simple program to add hours to convert UTC time. I want to type in a UTC time and have it convert for every state in Australia. [Code] Now that works fine however when the conversion goes past "midnight" it then shows the date and time. I have tried about 50 different things but cannot get it to remove the date when the converted time passes midnight. [Code] The string was not recognized as a valid DateTime. There is an unknown word starting at index 18.

I'm trying to make a program that adds a menu item when right clicking files.I got a C# code here:[URL] and converted it to VB.
It's working perfectly but the trouble is, it adds a menu item to folders and not files.
These are the registry entries i added:
Private Const MenuName As String = "FoldershellNewMenuOption"
Private Const Command As String = "FoldershellNewMenuOptioncommand"
convert them so it adds the menu item to a file?
I am using ASP.NET with VB.NET as background code. I have 8 ImageMaps in my webform Estimator.aspx.Each ImageMap represents a car part (Front Bumper, Rear Bumper, Mirror, Hood, Sunroof, DoorShell, Headlights, Tail lights) and I have a dropdownlist ddlChosenParts. When the user clicks on any of the 8 ImageMaps, I add the PostBackValue to the dropdownlist ddlChosenParts.The problem is that if the user clicks on the same ImageMap twice, the PostBackValue is added twice.I want to check if ddlChosenParts contains the ImageMap's PostBackValue and if it already contains it, do not add it again. That means that if the user clicks more than once on the same ImageMap, it's PostBackValue is only added once in ddlChosenParts.I have this code but i'm getting an error: Value of Type String cannot be converted to ListItem.

View 4 RepliesI have a ListView on one form that i am wanting to read the items and display on a different form. My code:
Dim oList As ListViewItem
For Each oList In fSOOrderEntry.OrderList.Items
lstDetail.Items.Add(oList)
[Code]....
I don't know what this means. i want to ADD each listviewitem from one listview into another listview.
I currently have a line of text in my listview that is too long for the current width of my
listview, without increasing the width of my listview, is there a way to add a newline within the
listview line item so that it's 2 or 3 lines long so there's no need to have the user scroll to see
the text?
I have an Access database with a Parts table. I'm using tableadapters in my project. A datagridview on my form is filled manually in code. One column of the DGV contains a columntype of combobox. I've got a bindingsource on my form whose source is the Parts tableadapter. The combobox column is tied to the bindingsource and is displaying fldDescription.
The part descriptions can be changed by the users, but the original part description is saved in another table that is used to fill the grid. If part "widget" gets changed to "widget, large" I can no longer display "widget" in the combobox of the grid. I need to know how to be able to add it to the bindingsource so I can display it in the combobox. I don't want it saved to the Parts table though.
I have made it so that as soon as the form opens it puts an icon in the tray and when you right click the icon it comes up with a contextmenustrip. in the form I have put a button and a textbox. when you click the button, it creates a new item in the contextmenustrip What I wanted to do was add a peice of code to this new item, is this possible?

View 13 Repliesi've written a database program which runs fine from the ide (vs 2008). when i install this program, all database operations do not work. i tried running it as an administrator using an admin command prompt, it worked. now for my less tech savvy clients, is it possible that when they right click the programs icon they can use the 'run as administrator' menu item? how can i achieve this. if it's too much to implement, will moving the database from the application path to, say, documents, solve this issue?

View 1 RepliesWhen adding a new item (class, control, etc) in C# it will automatically add a namespace to the file depending on the location in the project.
Is this also available for VB.NET?
The code 'Namespace DataClasses.AX' and 'End Namespace' would be generated.

View 5 RepliesFor the last couple of days I been trying to add items to a listbox from another class within a system.timer.
They just don't appear in the listbox. I don't get any errors. The items just don't get added :S.
I have:
Form.vb
make object of Control
Control.vb
Here I have a system.timer
In the Timer_Elapsed method I do this: form.listbox1.items.add("hello")
But it just doesn't work... When I add a new item to the listbox1 from the constructor or another method that has nothing to do with the timer it works...
I have been out of VB since VB 6, but am back into it to write a basic app. I have created a listbox and am able to add data to it from a textbox via a command button. However, I want to give the user the option to simply press the enter key after they have entered the info the textbox, instead of clicking on the command button. I tried calling the function the command button is using from the "ENTER" event on the textbox, but all that does is execute the function when I click on the textbox? I'm sure this is very simple. What am I missing?
