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 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]...

View 4 RepliesI 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,

View 1 RepliesI 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 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

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?
View 7 RepliesIm 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

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'.
I am trying to write a program that will have different group boxes,
each representing a question, and each one has radio button choices
I am trying to write the program so that a while loop will go through each group box and check answers of radio button choices
the codes I want to know is the command to access 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...
It appears to me to be right but always returns true.

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.
I was dividing a number from one textbox into another and when i tried something like 22 divided by 15 i just got one. Are listboxes not able to handle decimals?

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.

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 don't have an example code, but recently figured out how to make a single sub handle the keydown event for multiple text boxes.What I would like to know is if it is simple enough to have the object name that is sending the event instead of "microsoft..text: 54654" (sender.ToString in a debug window) type of return. I don't know how to make use of that.

View 1 RepliesI'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?
View 7 RepliesIs there a better way to make a form with multiple buttons opening different things than having a form that has lots group boxes for each tab. So in the begining each box will be invisible and when you click the button the corresponding group box will become visible. Is there any other way?It will be like a background image and it'll have buttons that will mask it with invisible buttons. when the button is clicked it will open the corresponding group box.

Why is that ? I even tried copying the check boxes from tab 3 to tab 2 but to my surprise they once again looked differently ! This only happens on tab 2 . How is this possible ?
