View 3 RepliesI have a problem with a generic list, which consists of intances of a class i created. I am just amazed, each time I add a new object to the list, it overwrites the previous entries. Here is a code sample, i just can't beleive it. I am using visual studio 2010:
Dim translations As List(Of TranslatedValue) = New List(Of TranslatedValue)
If Session("ctlTexts") Is Nothing Then
Dim reader As IDataReader = DataAccessFunctions.db.GetDataReader("SELECT [ControlID], [ControlTextEN], [ControlTextDE], [ControlTextBG] FROM [dbo].[tbLanguage]", GetConnectionString)

is there any way to populate a listbox with totals data from previous pages? I'm working on a project for a class where the final form needs to have all the totals from the previous 3 pages (each page has one total each), in some capacity (so I do not necessarily need to use a listbox if there is an easier way to do this).One thing about the previous 3 forms, two are set up in radiobuttons and one is set up w/a checkbox format (but I will likely change the radiobuttons over to checkboxes as a later revision).I just can't figure out how to populate the listbox with info from a previous form, I keep thinking load events, but that doesn't take into account which options might be taken from previous forms.once the totals from the previous forms have been added to the final form I will need to add a 7% sales tax. I assume that something such an if then statement will take care of that though.Just wanted to run that everyone here at the forum just in case there is a better way to do that.

i have the following piece of code: txtGrandTotal.Text = Val(textbox1.Text) + Val(textbox2.Text) + Val(textbox3.Text) If the numbers entered into textboxes1,2 and 3 are positive integers it all works fine, but if for example the following happens i get unexpected results textbox1 has the number 3, textbox2 has -1 and textbox3 has 6. I expect the result to be 8 (3-1=2 + 6) = 8 Instead I get 14. I understand the concept of precedent but how do I set it if I don't know if the number entered into textbox is positive or negative?

Im currently doing a small programme of a register system. I need to add a new group box filed with a few textboxes and a couple comboboxes for each entry in a access 2010 database. for example if i had someone called bob in my database with his details i would like the GUI of the VB app to add in a new textbox for the name, a textbox for the address ect in a set order, this needs to work for multiple entry's so the textboxes ect don't overlap but be placed neatly below the added textbox.

Whats the best way to add an adornment layer to legacy controls, or in other words you know jetbrains refactoring tools, how do they draw the squiggly lines under incorrect text? Also on another note can one draw said adorments on controls not under the direct reference of the application, ie using a handle? If you have insights, or just theories,

View 6 RepliesI have a couple of textboxes on my form. I'd like to give the user the opportunity to spell-check these textboxes so that they can correct their mistakes and then update the contents of the textbox into the database.
Only thing is, I'm not sure where to begin. I found this thread by Martin Liss, but it errors out for me as it's not .NET.

How to populate the txtboxes in another from by clicking the datagidview(in another form).
when I double click the item in datagridview, it will show the following information in the another form.
On my form, i've got some textboxes and some richtextboxes. I'm using the following code, to search through the text properties of each of the two types of control. see below:-
For Each ctl As Control In Me.Controls
If ctl.Text = "7777" Then
ctl.Text = "found the sevens"
End If

box.Text = "Found"
