GroupBox Refuses To Be Visible?
Jan 23, 2012
In my card game program, I have used 4 main GroupBoxes to act as dialogue boxes. Some contain additional GroupBoxes to house such things as RadioButtons, TextBoxes and CheckBoxes.Software places them when and where needed, so I usually move them apart in the Design screen to keep them all visible at once. However, with each new GroupBox I added to the program, their behaviour became increasingly vexing.In the design window, they are not allowed to overlap, or they will either partially or completely disappear. When they disappear, I have to find them with the Properties Viewer (when selected, the 4 sizing blocks appear and I can tease the drag symbol to appear).Worse, when my program is running, a GroupBox left in the Design mode in an "unfavoured location" (for lack of a better term) will refuse to appear when called.
I have single stepped past the code that positions the GroupBox and makes it visible and I have noted that the top and left positions are correct, but when I let the mouse hover over the word 'Visible' in the line "GroupBox1.Visible = True" the popup reports it as False.There is nothing I can do at run-time to make the GroupBox appear. I must return to the Design window and try moving it to a more favourable location.

I'm a beginner at using vb. I'm having a problem with making group boxes visible. I have two buttons: btnLevel1 & btnLevel2. When user clicks btnLevel1 GroupBox3 must be visible and GroupBox4 must be hidden. And when user clicks btnLevel2 GroupBox4 must be visible.

I am adding a several controls to a groupbox dynamically, but I can only see one of them. I am changing the location for each one just a little so so they should all be visible. When I count the rows in "dtOptionGroupOption it returns the correct #.
'Starting location for Options.
Dim intOptionLocationX As Integer = 0
Dim intOptionLocationY As Integer = 10

In visual basic.net I have been playing around with groupboxes and things of that nature, is there any way to group items into a box, say, buttons, and use the groupbox as a container to move / hold all of its contents while not being visible in any way? (no decoration perhaps?)
I've tried making the groupbox invisible but that makes all the items within the groupbox invisible as well.

I'm making a project that has a bunch of different types of calculators in the same tab within a tab control. To organize these calculators, I put each one in a groupbox, there are about 5 or 6 in all. When I was finished designing all of them, I placed all the groupboxes in the spot they needed to be, but once I started creating the events for them to be visible or not visible there are a bunch that don't show up. I think it has to do with the fact that VB thinks that the groupbox is part of another groupbox that isn't visible so it doesn't show.
How can I go about only showing a single calculator at once in my tab?

i have a sort of problem when i try to add some linklabels in my groupbox. I used this
Me.Controls.Add(Groupbox3)
Groupbox3.Controls.Add(FlowLayoutPanel)
I can only add 4 linklabels no matter how big is the groupbox, i tried autoscroll but nothing. How can i do to store minimum 20 linklabels in a groupbox? Here is the whole code i used:
Imports System.Net
Imports DevComponents.DotNetBar.Controls
Imports System.Windows.Forms[code]....
Is there any way, maybe with a specific reference to put a control that records what plays wmp activex and to save somewhere on your computer?

Here using VB .Net 2008. I seem to be having trouble getting group boxes to appear when I click a radio button.
For example:
CODE:
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:
CODE:
The second groupbox does not appear and is directly behind the first groupbox. The Top code doesn't seem to be working either.

I have an old app still written in VB2003 that required some changes, part of that was revamping a menu that isn't behaving.I've deleted it and it doesn't show in the designer but when I start the program there it is, and still not correct.How do I really get rid of it so I can build another one?I'd hate to have to delete the whole MainMenu, this is the 5th in line, that would be a lot of re-creating.

I've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!

Okay so ive got this project iv been working on. Almost ready to get the beta on its way, last thing I needed to do is retrieve the EXE and change its icon. I found the EXE in the "bin" folder. Copied it to desktop. I went through the properties, no way to do it. Then I searched youtube, and google. Only possible way to change it I found was to use softwares. I tried Resource Hacker (ive used years back, this program was handy), but it didnt work. I replaced the default window-looking box icon with my icon, and that seemed fine. But once I saved and exit, the new file with updated icon was supposed to be created. Well it was, except just looking at the file icon I knew it didnt work. But when I right click and go to properties, that one changed. So why dosnt the MAIN icon change? In RH I seen no other icons

It seems that my form refuses to draw quickly enough. I am using this
[code]...
This ends with the form freezing for a moment, and then it resizes, but it's not until the end of the resize does it display properly, during the resize, their is a big black bar where the new part of the form is supposed to be.And when it's done resizing, it draws itself correctly.

In this windows forms app, I have a form with six comboboxes. Two are parents, one with a single child and the other with three children. All of these work beautifully except for one of the children. The code for each one is identical, and I've verified the query against the database a dozen times. I even have another of the children that is in the very same block of code. One works beautifully, the other one refuses to populate any data. Below is the code for the one that doesn't work. I would tell you on what line the error occurs, but it doesn't throw any errors. Try catches show nothing, and I have VS 2010 set to throw all errors, but I get nothing, just an empty combo box where there should be a list of names.
Public Class errorTracking_submit
Dim ConnectionString = "Data Source=dvmx6030MS2005_DEV1, 2755; user id =CRCUser;password=TWC5uck5;database=CRCTools;Connection Timeout=5"

I've spent weeks working on a project. I develop on both of my computers (Desktop and Laptop) which are both equipped with VS Express 2010. The programs debug, and compile with no issues on both of my machines, even when the .exe is removed from the debug folder and placed elsewhere. However, when I try and run the program on my brother's computer, the initial form jumps up on the screen as desired. Then the program is designed to open the next form upon the click of a button. When that button is pushed, we get the following:
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

I've searched everywhere to find out why the heck my program is doing this, but couldn't find anything like it...? I'm making a flash card program. Part of my program takes images corresponding to other data from a certain area, chosen by the user, and moves them to another folder, for later use. I want to store the path for the image next to the other data, storing the path as a string. When no image is chosen, the variable for the path is simply "no image".

I have an object (ClassGPS) containing a DataTable that is exposed through the property "Satellites". My form has a bindingsource that, upon load, associates itself to a new ClassGPS object. The table has 5 columns, two of which ("PRN" and "dB") I want to chart using the new 4.0 chart tool. So the chart object's DataSource = ClassGPSBindingSource, and the DataMember = Satellites. That is all set in the designer.In ClassGPS.New(), the table is pre-loaded with 4 rows. This object is created before the form loads. When the form loads and the bindingsource is set to the created GPS object, the chart correctly updates and displays the four pre-loaded entries.On this form, I have a button that adds more entries. Tracing from the Click event, pushing the button does add the entries properly to the underlying table, and if I create a ListCHanged handler on the data source, the events are all correctly firing, but the Chart does not update to reflect the changes.
So to test, I added a Datagridview object. Just like the chart, I set its datasource to ClassGPSBindingSource, and the DataMember to Satellites. And here's where it gets weird. In the designer, the newly added DataGridView control has 4 columns in it labeled RowVersion, Row, IsNew, and IsEdit. I didn't create these columns, it does it itself. If I try to change the bindings on these columns to reflect the actual datatable names (PRN and dB) two things can happen:
1) If I hit Play (F5) to debug the program, the DataGridView looks and acts correctly inside the program and is correctly bound and updating fine as I add new data. In the designer underneath however, the changed columns have disappeared and are replaced with the original four it is creating for no apparent reason. When the debug session terminates, the columns - which just finished functioning fine in the debug session - are now gone.
2) If I hit Build, the designer destroys my columns immediately and recreates those it defaulted to.In either case, something very fishy is going on... in that the Chart, with the exact same binding settings as the datagridview, does not work but the datagridview works just fine (unless Build is hit prior to Run).Has anyone run across this? Can you reproduce it? I have bound a chart to a datatable before and it worked just fine, but it didn't have to update except when the form it was on was closed and later re-loaded.

I have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

I have a typical databound Form with a bound ComboBox bound on the form Load event.I have a typical BindingSource and BindingNavigator Control with an "AddNew" button.When a new record is added to the dataentry form (i.e. not the combobox) I intend the combobox to default to the first value in the list by setting...
mycombo.selectedindex = 0
I have this in the BindingNavigatorAddNewItem_Click event but it has no effect! I also tried placing mycombo.selectedindex = 0 in the BindingSource "AddingNew" event but this also has no effect. I have discovered that the "selectedindex" is somehow inexplicably changing itself back to -1 As an experiment I added a button to the form and on the click event pasted "mycombo.selectedindex = 1".I added a newrecord then clicked this button and the combobox updated as expected. But I wont this to work as I'm adding a record!Is there a particular event where I should set mycombo.selectedindex = 1 apart from the two I mentioned?

I have a need to add 16 radio buttons to a groupbox but I want to be able to select 2 radiobuttons per groupbox. (2 vertical columns of 8 radio buttons each) The radiobuttons are created dynamically and each set of eight have different names to distinguish them. Do I really have to create 2 groupboxes and put each set of 8 in each groupbox and put those groupboxes into my parent groupbox? Is that it with radio buttons...if they are all in 1 groupbox then there is no way to select more than one at once?
