View 15 RepliesI am wanting to create a menu based on items in my MS SQL database i have 3 tables
FormTbl
FormID - Int Eg (1)
FormName - nvarchar(50) Eg (Form1)

I can get the form names to be populated in to the menu and can open it my question is how do i set where the menu items will be placed. Eg File with FormHierarch 0 will be the very first one. Exit with FormHierarch 0.1 will be the very first one under File

I need to update a table with values from a listbox. I am trying to create as many parameters as there are items in the list, my code below, but how do i name them differently? so that they dont' overwrite each other?
For Each item As ListItem In ris

pID.Value = objFormat.CheckSQL(item.Value)

and on the SQL side, is it possible to write an update statement, that will take a dynamic number of parameters?

I use a menustrip as the main navigation for my program. Currently I have separate code for the menustip on each page. Recently I found that I could create a form template using inheritance and include the menu strip on the template. The problem I run into is that when I open another form using the menu strip the original form is still open and my references to me.close are no longer active. Is there a way to close the form that the user is leaving?

View 1 RepliesI have started a new blank project for VB 2007. I have taken the old code (VB 2003) and added it to the project.The line marked below worked on the old VB, now it does not. I get the following error:
Object reference not set to an instance of an object.
Troubleshooting tips:
Use the "new" keyword to create an object instance.
Check to determine if the object is null before calling the method.I have tried several forms of using the "New" keyword and still get the error.

I need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)

I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

so it would be something like this
