I have to make a lot of retangular boxes to make my program neat but i'm having a problem of adding boxes. I tried using the draw event in the tab page but everytime i scroll it will draw the lines again and messes up everything. Also when making a line greater that the tab page, autoscroll won't work.Is there a way to make lines or boxes in design time?

View 9 RepliesI need an indexed set of picture boxes. The number, n, of these objects is determined at run-time.Migrating from VB6!! I had used the load command n times to create a control array from a "seed" picture box. In code the individual pictureboxes are accessed as formula(k), where formula was the name of the control array and k is an integer. Examples can be seen at url... the chemical formulae, Ni2+ etc., are draggable picture boxes (curve captions if you like), so that they can be placed wherever the user wants.How can I implement something similar in VB.NET?

I need a quick way to easily check and edit the content and properties of the textboxes I'm going to use.I thought I could have an array of textboxes and then access each textbox like this..[code]I declared cell() as a global variable under the "module variables" . The code shows no errors but the textbox doesn't show.
View 3 RepliesHow can you put the out put in an array that has no text boxes? [code]Say this is the code, but what you need is for it to show even more of a break down something like this with the select case.[code]and yet the text file that it needs to read from is delimited by a comna and the amount of the vehicles that are there for the out put changes.I was wanting to use an "If/Then" or an "If/ElseIf/Then" statement nestle into the case statements for the output. What I really need is a place to read some good articles on arrays as I am still fairly new and do not understand fully how they work(which I think is causing my problem.)

Maybe i should to somehow make an array list of all 30 Picture boxes?
I have created this code to reset my picture boxes to default locations upon form load.
my sub:
Code:
Sub reset_Alien_locations()
Dim Xlocation As Integer = 26
For segmentIndex As Integer = 0 To AlienArray.Length - 114
[Code]...
I have this sub load up upon form_load event. Yet it doesn't do a thing! I want each picture box to appear on the same row, hence the y axis is set to 49. but I want my X-axis to be added by 30, so that there is a gap of 30 pixels between each picture box, hence the x point is: Xlocation = Xlocation + 30
I need to bind a textblock.text property to a single element in an observable collection, or array element, and have the text update using the INotifyPropertyChanged or INotifyCollectionChanged, whichever is best.
Most examples describe ways to bind listboxes or other list views to entire collections, but my application needs to update several textblocks on a screen depending on notification of a change in one or more elements of an array.
textblock1.Text = MyArray(0)...
textblock2.Text = MyArray(1)...
textblock3.Text = MyArray(2)...
textblock4.Text = MyArray(3)...
Is it possible to bind a single textblock to a single array element? Is it possible to get notification of the proper type that will update one or more of the textblocks if any assigned element changes?
I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.
CODE:
I have 81 text boxes on a form and would like to create a text array in code that will equate to these boxes on the form. Once I've assigned each text box from the form to the array entry, I'd just like to work with the array - then have the actual text boxes on the form reflect the changes made to the array.

View 4 Repliesi am very new to VB and have been trying to make a hangman game. I was wandering if there is a way to add multiple label boxes to a form based on the size of an array. For example a user inputs the word h-e-l-l-o in a input box that word is then split and put into an array(arrword) then i want the main form to appear with 5 label boxes each one containing a letter that from the array(arrword)
View 8 RepliesI'm trying to lern VS 2010 from VB 6 and one of the things i'm hawing a problem whid is control array.In vb 6 if you create a text box it's named "Text1" and if you yust copy it and paste it it renames to "Text1(0)" and the new one's name is "Text1(0)" and the code would lock like this

then it would print for each loop the random result in one of the text boxes corresponding to i.
How do i do this in VS 2010?

View 2 RepliesI need some code to draw a resizable, draggable rectangular cursor (or selection box) on a picturebox. I found some excellent code (albeit rather old) that does just that, but on a form rather than a picturebox. I have tried converting the code - basically moving things to the picturebox events (Paint, MouseDown, MouseMove etc). It nearly works but leaves a trail behind it when you move or resize the cursor. In other words, the selection rectangle is not being erased before being drawn in the new position.
Is there some fundamental difference between drawing graphics on a form and drawing on a picturebox that would cause this behaviour? Something like, when you invalidate a form and cause a redraw it erases what you did last? If not, then I just need to dig a bit further and work out how the cursor is being erased from the previous position.
Here's the original code that works fine on a form:
Private DragRect As New RectangleF(20, 20, 100, 80)
Private Adornments(7) As RectangleF
Private MouseInRect As Boolean = False
[Code]....
Say I have 3 Buttons, labelled: Unit 1, Unit 2 and Unit 3. When I click on any button I want a drawing of that unit to appear on screen at a pre-specified starting point. Thereafter when I press any other one of the buttons the unit drawings appear alongside each other in a line. So I could end up with:

With this line...

So as the name states; I am a newer coder.
This is the code i have:
Public Sub RandomNumbers()
Dim s(4) As String
Dim RandomNumber As Byte
I don't know if you can tell what I am trying to do here, so I will try to explain. I what to create for random numbers and place them into for different text boxes. I also would like to do this with combo boxes and their selected indexes. So if the combo box has 10 items in it; the new selected index would be the random number generated above.
I'm in the middle of creating an application that will be used to input customer information whilst the customer is speaking to someone over the phone. This involves the customer giving the employee information such as name, address, postcode etc and the employee inputting that information into text boxes and combo boxes that are in the application.
What I would like to be able to do is after the customers information is given over the phone, I need to be able to send that information to a database which will probably most likely be done by button click. In this case, I'm using Microsoft Access. I'm also hoping that I can do this within Visual Basic coding.
The database is set out with multiple tables which include a customer table and a ticket table and both have multiple fields such as first name, surname in the customers table. Both of these tables are in use with the information that the customer gives over the phone.
I've already asked on other forums and people are where replying giving me third party programs that I could use to implement this, something I don't really want to do.
