I am currently trying to allocate a number of group boxes dynamically. Previously (in other languages) when I have carried out something like this I have used the '&' to substitute the contents of the variable direct into the code I.E
For I = 1 to 20
Groupboxname = "GroupBox"+I
Weatherstates.&groupbox.controlls.add(obutton)
next
This would then have the result of creating a button in all the group boxes, however this does not appear to work in VB .net 2010
I have looked at Directcast, but i am a even more confused. Is there a simple way to substitute the contents of a variable into the code ?
I've coded a Login form with two text boxes and two buttons goes to a Users database to validate the userid and password. When I click the OK button (button1) I get an error message on the highlighted line below(Dim Reader).

I am having trouble coming up with a way to add a selected radio button in a selected group box together.I have 3 group boxes each accessed by a checkbox within each group box there is 3 to 4 radio buttons. I would like to know how to add the selected radio buttons in each group box together and display them in a textbox by clicking a button "calculate". I believe I would have to make a global variable but I dont know where to start.
Private Sub Calculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Calculatebtn.Click
Dim answer As String

I know this code is wrong but I was just trying to remember the calculate function.Is there a command that uses the selected radio button from the group boxes then I would be able to input that into my calculate button sub?
I understand because it has to be ON/OFF it won't go through to any other radio buttons in the group box. Would the best way is to use a hidden radio button that would switch control between the two? There's only two radio buttons i need to tab through, what's the best way to tackle this?

I have 8 check boxes and 4 radio buttons on a child form. When the User checks a Check Box, they then select a radio button. They will do this for 1 to 8 of the check boxes. The only way I could think of to keep track of this is create 8 panels with 4 unique radio buttons in each. Then I would set the visibility to each one accordingly. This method has other logistical errors than just trying to get the design view worked out.
I was wondering if there was a way to just use the radio buttons. I thought I could set a boolean variable to keep track of each Check Box's Radio buttons. Or an integer variable. For instance, if Check Box 1 is checked and Radio Button 1 is checked then myVariable's value is 1 or whatever. Then when I actually run the app, I can check the value of the variable do do what I need. Does this sounds plausible?
I am trying to write a program that will have different group boxes,

and also how to keep each group box "seperate" enough that i can use same radio button names for all the group boxes...

View 1 RepliesI can whip up a program that deals with text boxes, buttons, checkboxes, etc. fairly easily. I know how to deal with arrays and stuff like that, and I am just barely able to open/write to files (I don't quite have it down, but almost). However, when it comes to drawing graphics. Right now all I'm looking to do is create a function that will draw a pixel or really tiny rectangle at my command to use as the building block of drawing images. I saw some example code here:
Of how to have it draw a rectangle upon opening a form, and I was able to do that. But I guess I'm not quite sure how to make a function like that be performed when I do something like press a button (or just anywhere in a segment of code).It's probably because I don't understand this line:
[code...]
I understand that it makes a non-public sub called Form1_Paint, but I'm not quite sure about the arguments passed and what "Handles Me.Paint" really means. I'm not sure how to make this (if I can make it) into a function that I can call anywhere (in the button1.click code, for example) to make it display a pixel.
how I could do that? Either that, or just explain what the piece of code above is actually saying?
I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.

View 1 RepliesI need to be able to add (specific) special characters to text boxes. Problem is, there are five of them spread across two forms and three tabpages. What I'd like to do is bring up a form when the user presses something like "F2" while the text boxes are focused, then on that form would be a grid of buttons. When the user pushes a button, the character is added to the box. How do I get this form to reference the box that called it without passing a global variable or calling a public function? I tried Form3.Parent.Name, but that always seems to refer to nothing. Also, once this is done how can I get it to just insert a character where the cursor on the calling box is? It probably shouldn't even be on a form either since that will take the focus when it's called (which I don't want)
View 3 RepliesI need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..
What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.

I'm using vb.net. Basically, I have a drop down list, text box and a submit button. You choose a movie director from a drop down list, then type in a movie, click button and it adds the data to my database.There's another button which hides/shows drop down list, text box and submit button using Visible = True and Visible = False, but what I don't like about it is when it hides the things I said before, it leaves some white/empty space like if they are still there, but not visible.Is there anyway to put some kind of holder/container and place a button which when clicked could add my drop down list, text box and submit buttons to that place?
