VS 2008 : Getting Values Of All Text Boxes Within A Group?
Aug 25, 2011
Im attempting to loop through all the text boxes inside of a group box, and add the text into a list box to later be written to a text file. Here is the code I am using.
Dim cControl As Control
Dim FILE_NAME As String = "Tester.efw"
Dim Group As GroupBox
[code]....
Now instead of locating only the text boxes, apparently it is still trying to identify the labels as text boxes, because I am getting this error:Unable to cast object of type 'System.Windows.Forms.Label' to type 'System.Windows.Forms.GroupBox'.

So basically what I'm trying to do is write data from an XML file (a "save file") back into the form. My controls are in all different group boxes (makes it much easier for showing and hiding groups of controls dynamically). I thought about and am putting each control's Parent name into the file, but can't figure out how to get that parent name back into the DirectCast within a For...Next loop so it will actually cast the data into the control.

I am trying to follow the book 'Sams teach yourself VB 2008'. It was going well until the end of hour 4. For exercise 1 I have created the form with a button and two text boxes, but cannot work out the code I need to move text between the two boxes. The Object Browser does not seem to help - am I reading it wrong?

I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

Is there a way to compare values in text boxes?
For example, if I have two text boxes, I want to compare the numbers in each to see which is higher and then commit actions if one if higher.

I have written some code to get the data from a number of text boxes all named in the style txb_[column name]
I want to write this data to a datatable.
The text boxes were initially filled using a row 'aIndex' from the datatable, then the user can edit the data.
When this code runs, the text boxes all revert to their initial values, regardless of any changes made to their contents during runtime.[code]...

Form1 has 2 public string variables defined and initialized to "" (an empty string).Form2 has 2 text boxes and a button. When the button is clicked the public variables on Form1 get set to the values in the text boxes.This works fine.I recently had to add a module to my project so that I could use Main as the startup item. Ever since doing that the above no longer works.The variables never get set to the values in the text boxes. They just stay empty.My Main code is simply this for now:
Dim f As New Form1
Application.Run(f)

I am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.

I have a groupbox with 12 checkboxes(containing months of the year). I need to calculate and display the value in a text box.
For example if one check box is checked then on clicking the button calculate, it should be able to display the value 500 in the text box, if two checkboxes is checked then the total should be 1000, if three check boxes then total should be 1500 and so on[code]...

The other day I needed to know how to handle a group of form items in one function, specifically speaking I needed to uncheck all ListBoxes in a group of a MenuStrip when any other was checked. Now I need something similar, except this time it's just a group of check boxes on a panel. heres the code I used for the other purpose.

I have a form that has group boxes of various controls for data input. One of the group boxes contains a user control. This user control can be 1 of 7 I have depending on the type of data I wish my user to load. The 7 user controls are all of various size. My form is a fixed size, and i have allowed room for the user control to fit the largest. However, the smallest one has a lot of space obviously. The resizing of the form itself I am struggling with. It has to be the size it is at now as there is a tab control,

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 ?

New user here using VB .Net 2008
I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
If radiobutton1.Checked Then
Groupbox1.Visible = True
Groupbox2.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.
Eg:
If radiobutton2.Checked Then
Groupbox2.Visible = True
Groupbox1.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If
The second groupbox does not appear and is directly behind the first groupbox.
The .Top code doesn't seem to be working either.

I put some group boxes on a user interface and now labels and pictures that are set to visible can't be seen even when the group box is set to visible = false. (I have the group box and the pictures and labels in the same place on the form and was planning on using buttons to make them visible and invisible but the pictures and labels stay invisible no matter what while being in the same place as the group box.)
Does anyone know why group boxes do a sound job of making things invisible and how to correct it?

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
[code]....
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 written a code and tried linking up groupboxes from my input form called input.vb and the output form called results.vb.
[Code]...
I have used the above codes to access groupboxes from both forms. However, at run time I get errors saying "InvalidCastException was unhandled" and below that it says "Conversion from string to DOuble is not valid". This error points to a value in a group box that is actually hidden or disabled.

how to permanently save to text files then re-open all of the information again using SFD and OFD. Now my teacher has come back at me and said that i need to be able to save the information from multiple text boxes and have the text in certain labels to also be saved into the one text file (the labels need to be done because it is a database and these labels are like the fields and the right text box needs to match the right label)

I'm fiddling around with trying to make a sort of map/world. I'm using 16 x 16 pictureboxes named PictureBox1, PictureBox2, etcThe issue is that when I put the images into all the pictureboxes, I have to have a line for each picturebox (so say I have 100 boxes, I have 100 lines).The only difference in each line is the picturebox number, the rest is identical. I'm basically telling it to set that picturebox's image based on the number that a variable I've created has stored.I've got a game idea, and I'm just trying to figure out how to do the map. I want it to work like the old school RPG games like Dragon Warrior, or the more recent Dwarf Fortress. I'm still not sure if I want to use graphics or letters. At this point, I'm just trying to figure out how I can create the main screen where the user moves around. This is what I've come up with, as it works with what I know. I'm pretty new to this, although I've messed around with VB6 a lot.
Dim tile(30) As Integer
Dim tilelocation(3) As String
Dim x As Integer
