All the controls on one of my forms has vanished. I was attempting to doubleclick a radio button to get to the CheckedChange event, go some sort of COM error, then the next thing all my controls dissapeared off the form. I got some other strange things happening.[code]...
View 8 RepliesI went to go open up my form a minute ago and everything is missing!!! It is all there, but it is not. The form looks like a completely blank form with nothing on it. But all the controls are still there, somewhere, because if I click the dropdown at the top of the properties window, I still see all my controls, and my code does not have errors. It was working fine 10 minutes ago!!
View 16 RepliesIn the project I'm working on, I was editing a class and when I got done, I clicked save all. I moved on to my main form's designer. When it came up, the custom tab control I have on the form was blank. There used to be a ton of controls in it, so I am extremely confused about where everything went.I checked the properties window and it thinks everything is still there:ut when I check the Document Outline window, everything is gone. The tab control is still there, "AVERT Wizard", but all of it's child controls and tab pages are gone.

View 4 RepliesI was designing a Form in VS.NET but the form controls etc have dissappeared. I am left with a pnael which i can write code in but cant see the Form or its controls.
However - if i press the play button then i appears again but dissapears again when i close the form after playing it.
I don't know what happened I compiled the program and everything just disappeared from my main form....i can't name buttons the same thing that i recently had before everything disappeared so i know it still has to be there somewhere, i just don't know what to do.
View 8 RepliesI have a vb.net application, it is so far so good in high resolution. When I set the screen resolution of the machine to | 800 x 600, the header of the Save button has disappeared. If you look at the attached file, that means caption "F12" disappeared. I tested it in different machines, sometimes it is there but it may not be there in other machine.
I don't know whether it is the code error or machine environment setting up.

I've just started using Visual Basic - I'm completely new to programming altogether and thought it might be a useful skill - and I've been slowly working my way through the tutorials - from 'Learn VB' in the Start Page - and now the MsgBox function has disappeared! I have no idea why, as I'm doing the same thing (I think) as I was always doing. New Project > Windows Forms Application > Right Click on 'Form 1' in the solutions box > Source Code. Anyhow; when I type MsgBox there is neither a dropdown box with that name (IDE I think it's called?) and it becomes underlined with a squiggly blue line. I seem to remember that, in the IDE box, there were several different types of logos next to each name, but now only the logo that shows a windows with what looks like green highlighter written on it (you can see it if you type in #If) appears. I've already restarted the computer (via the start menu).
ps. I'm Running 'Visual Basic Express 2008' - and downloaded that yesterday (23/11/09)
I am using VS2010 Pro and can no longer see the step into command buttons on the toolbar. That and the step out have disappeared. I know I had many more toolbar buttons across the top that I don't see now but the debug toolbar is checked but there isn't even the step into or step out options to add to the toolbar.

View 3 RepliesGreetings. I have a DataGridView control in a form, and as of a day ago, when I click on the control, I get *no* properties listed in the Properties pane of the IDE. The properties pane is totally blank. Neither properties nor events are visible. I have tried everything. Prior to this, the properties and events displayed normally.
Other controls' properties are displayed when I click on them, but not the DataGridView control. If, after clicking on my DataGridView control, I use the combo-box on the Properties pane to look at any other control's properties, they come right up. If I then select my control's name (DataGridView1) in the Properties pane combo-box, the IDE crashes completely and I have to restart.
I tried a repair re-installation. The same things happens.
I can set properties etc. programatically, but that sorta defeats the point of an IDE, not so?
For some reason a control on my form has disappeared. I can select it in the properties window and view all the properties (Visible = True) but I can't see it. It also doesn't appear when I run the form. How can I delete it, or bring it back?
View 1 RepliesI have been using a tabcontrol with multiple tabpages. On one particular tabpage I accept a value into a textbox which has worked many times. For some reason the textbox has now disappeared {clumsy thumbs are always a possibility}. However, when I try to put a new textbox in its place I find the textbox name already exists. I look for the name in the components address box in the properties sections of the ide and it doesn't exist?
View 3 RepliesYesterday I added a new user control to a project I was working on: right click on the project name "Estimator", then add, then new item, then on the add new item dialog I typed the name of the user control, and I created my ButtonWithCheck.vb control.
My user control appeared on the toolbox, I inserted it in a form, used it, kept working on my project, and everything was fine. I saved and closed the solution.
Today I open the solution and I got an error: "Could not find type 'Estimator.ButtonWithCheck'. Please make sure..."
Why a project saved while working doesn't load?
I created a Windows Forms Application and spent a lot of time putting it together. This is my first project like it, it works correctly and... I'm very happy with it. However, I didn't open Visual Studio for a couple weeks. And when I went back to open the project's .sln file to edit it again, I can no longer see the design view with the layout of the program and all its objects (textboxes, labels, buttons, etc).
When I open a brand new Windows Forms Application, I can Right click the Form1.vb file in the Solution Explorer and "View Designer." Here is a picture. Now, when I right click on the .vb file from my program, that option is not there. As you can see, my program has a lot of objects. So I'm getting a concerned that I did something wrong and will not be able to use the design mode any more.
We have this custom DateTimePicker in our project where you can alter the BackColor and so on. But normally, when you click on the month of a DateTimePicker, it gets highlighted and you can change it with for example the arrow buttons on your keyboard or by typing a different number. Now the problem is that in our DateTimePicker, the highlighting doesn't happen anymore. When you click on for example month, you'll be able to change month but you don't see wether you selected month or something else.
This is the code we have (it's old code from way before I even started working here):
Public Class ucBaseDateTimePicker
Inherits System.Windows.Forms.DateTimePicker
' true, when no date shall be displayed (empty DateTimePicker)

The charting control has disappeared from my toolbox in VS2010. I know it was there when I upgraded to 2010 a few weeks ago. Both chart items are checked in the Choose Toolbox Items dialog but it doesn't show up in the toolbox. I'm pretty sure it was under the Data category. I tried resetting the toolbox but that didnt bring it back.

View 1 RepliesI have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

View 3 RepliesI'm trying to access the "My" namespace, and it's missing everything except "Settings", "MySettings" and "Resources". I've looked in Microsoft.VisualBasic.Devices and all the references seem to be there, by the My namespace itself isn't working right.
Another thing that's not working is the ''' XML documentation function. Normally, typing those apostrophes in the right place spawns a big mass of UML commenting for Intellisense entries but now, nothing. I've tried both of these from my user account on the same PC and they work fine; presumably it's something my predecessor has inflicted onto his own settings in VS2010.
Does anyone know how I can fix this and go back to using Visual Studio as I know and love it? EDIT: I got sick of this behaviour and decided to move over to my username, where I'd verified the My namespace was fully working. Turns out that the problem reoccurred once I'd gotten the project working under my username, so it's presumably a project setting which has been turned off somewhere, as starting another project still creates an environment where "My" and the ''' comments work, but the problem project still doesn't have either feature.
I wanted to know if anyone could tell me how to access the Click_event.I have a boarderles form with a panel control which has the Dock property set to fill and on the panel I have placed a Label also with the Dock property set to fill. I also have a timer running.How can I get code to execute in the Label1 click event.I've tried doing it by using the generic Click_event and also with two variations of the Click_event Handles parameters

There is newer code in a follow up post. I suggest using the code in the later post rather than the code in this one. You can still read this post though. When designing a user interface, one should be conscious of how many individual controls are required to implement the functionality. In some cases an initial design may begin with many buttons or textboxes (for example) but then further review of
the actual required functionality allows for a reduction in the number of unique controls.
But other times, there isn't a better way (which will still make sense to the user of the application) then to have a series of many repeated controls. So in the cases where one can be certain that the best UI implementation for an application will require the use of multiple copies of a given control, then it often becomes necessary to maintain some method of managing all of those controls at various points
throughout the application. Doing so typically requires that one build up some collection of controls which can then be accessed by index in order to work with any given control; but this can lead to a lot of clutter in the code file which handles these control's events. For instance there will be some kind of collection declaration, some recursive routine to find all of the controls of interest, and then any number of event handler methods with long lists of Handles clauses, or additional code loops to wire up the event handling for each control.
Purpose Since most of this functionality could be considered a requirement regardless of the type of control being managed, or its required functionality, it may make sense to wrap all of the control management functionality into a single class. And since our first requirement is a collection of controls, then a base collection class could be the perfect starting point for our control manager. There are a number of existing thread around this topic, with some recent (at the time of this writing) ones being:[URL]..In this, and related, threads I have posted examples of a simple TextBoxManager and ButtonManager control. But again, with so much similar functionality required regardless of the control being managed, it would be technically possible to create a generic ControlManager(Of T As Control) class which can manage any type of control.
[Code]...
So in summary, one can facilitate managing a large number of user interface controls by building a "control manager" class which both encapsulates the list of control instances, and deals with adding and removing defined event handlers for every control it manages. The generic control manager class itself can be inherited and extended into a more specific class on a per-application basis in order to provide more application-specific functionality.

If I have the following ListView, how can I attach a SelectedIndexChanged event listener to the DropDownList so I can perform a command on the respective object? Imagine I have a list of new users and I want to add them to a usergroup by selecting the group from the DropDownList.

I have a maximized form that has controls at the top of it and a large DataGridView that is docked below all the controls. Its kind of like the Ribbon in MS Office. The controls cover about 1/4 of the screen at the top. I would like a way for the user to click a button to hide all the controls then automatically expand into the place the controls were so the user can view more data in the DataGridView and visa versa. For example, in MS Office Excel you can hide the ribbon by clicking a tiny button that has "^" on it.
I'm not very familiar with all the controls in Visual Studio so I would like to hear some recommendations. Is this situation ideal for a SplitContainer or ToolStripContainer or am I way off base here?
I've got a couple of these NumericUpDown controls I put on a form. Without describing too much about the form I basically want to update some variables each time one of these NumUD controls changes value. So for each NumUD I have a call to a Recalculate subroutine within their "changedValue" event.
There are actually two problems. First, if I initialize the "Value" property to something other than zero in VB2010 at DESIGN TIME it won't even open the form when I hit RUN. It gives me a "No Source Available. No symbols loaded for any call stack frame" error. The error box says "InvalidOperationException" was not handled. So if I try to set the initial value of the Value property to anything but zero of either I get this error.
[Code]...
I've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out. After all this time I remembered about it again.If I create a usercontrol/containercontrol and add one or more controls to the controls surface, I just cannot figure out how to access the controls at design time.
