I have a form-based application, that until recently displayed the controls on the form when in Design. For the last week or so, when I go to Design mode for the form, it is blank. However, the program does work correctly. And, I can see the control definitions in form.designer.vb. How can I get my form to display the controls again so I can add/move/change it going forward?
Visual Studio 2010

Every once in awhile when I double click on a form in design mode (Windows Forms Application) that contains a tab control, all of the controls on the tab control disappear. I have to reopen the form to get them all back. In addition to this, the column order of my columns on any datagrid inside a tab control get rearranged when this happens. Is this a known bug and if so is there a hot fix or patch?
View 2 RepliesI've been coding an application over the last few months in VB.NET 2005 and have noticed that as the application is growing in size, I'm beginning to experience some strange behaviour in the IDE.For example : I have a tabcontrol docked in a form with 5 tabs. Each tab has a panel docked to it with several buttons, text fields, layout tables, datagrids etc. Sometimes immediately after saving the project, one of the tabs will go "white" and show no controls at all. There might be the odd outline of a control ( like you get when a control is hidden behind another ) but the only way to get them back is to close the project and open it again. It seems to be getting worse as the number of controls dropped onto the forms increases. Looking in the form designer.vb file I see that there are currently around 8000 lines.Is it possible that the designer file is so large that its having trouble loading/refreshing the view in the IDE ?
View 2 RepliesI am using Visual studio express 2008. I was working on a VB project for a few hours. Then I did something,(I think I just double clicked the form ) and I cannot open it in design mode. By Design mode I mean so you can see the controls, and ad buttons and stuff. The form still runs, if I run it. I see the form in the Solution explorer. From solution explorer, if I show all Files , then open FrmMain.Designer.vb, I can see my code. If I go to the project menu item and insert New Windows Form the new form works like I expect it too, I can see it. I need to be able to see my form.

View 2 RepliesWhen try to open in design mode a form (VB.NET), in which I have a custom UserControl, I see the message from Visual Studio:

The control MyNamespace.MyUserControl has thrown an unhandled exception in the designer and has been disabled.

And the form is not displayed in designer. What to do?
I have created a custom Combobox and added it to my toolbox, and it works well. Now I have added a custom ListBox to the same file as the combo box, but it does not show on my designer when I place it. I can however add it at runtime.
''ComboBox
<DefaultEvent("SelectedIndexChanged"), _
ToolboxBitmap(GetType(System.Windows.Forms.ComboBox))> _
Public Class ProjectsComboBox
Inherits ComboBox
''My Customization

I have tried removing the "DefaultEvent..." and still no dice.

I have a form where I have created a custom property, DataEntryRole, and set its Browsable attribute to True, as shown:
<Browsable(True)> _
Public Property DataEntryRole() As UserRole.PossibleRoles
Get
Return mDataEntryRole
End Get
[Code]...
When I view the designer for my form, DataEntryRole doesn't appear in the property box. I assume that it should appear if I were to create another form that inherited from this base form, but that's not what I want. I want this property to show up in my current form.
I have created a form and dropped a MicrosoftReportViewer onto the form. It appears in the control panel on the bottom of the design view but it will not show up in the form. This is the second form I have done like this. The first one is fine. I can see the report viewer in the form and reports work correctly. For the second form nothing. Something I did notice is that in the first form the ReportViewer1 has a name in properties. In the second form there is no line with the name of the control.
View 4 Replieswhy when I use My.Settings to Add items during design mode, they do not show up during run mode?
This is for a custom control.
I'm missing something between the control that exists on a Form during design-mode and the (apparently new) control that's created during run mode.
I can add items in design mode using the Application Settings editor (right-click on custom control, select Properties then Settings). But when I use code in a smart panel during design-mode along with My.Settings.MyProperty.Add() to add additional items, the new items show-up in design mode but revert back to the old set during run-mode.
How can I get back the design view mode in Visual Studio 2008? I closed the design view mode and I can't see any option to view my form in design mode.
View 10 RepliesI am using Visual Basic 2010 Express. I have a form with some text boxes on it. There was some code on that form which was giving errors. So I deleted the whole code. Now the problem is, I cannot see the form Design mode button to view it in design mode. But when I hit F5, I can see all the text boxes (in Run mode). I want to add some more controls on form. How to resolve this problem?
View 2 RepliesI am getting trouble in designing report. The interface of design and view mode is different. the alignment of the view mode for paragraphs are different from the design.
The following is my design interface:
The following is my view mode:
All the setting are the same, but there has different on it.
I accidentally deleted a tab in the design mode. I still have an old form in which the tab is present. But it is an old copy from the present project, hence is it not in the same project. What can I do best to get it back? By the way, Visual studio could better say some warning before they do that. And contr-z did not get all the content back. May-be I should have hit that button a few times more before I pressed save. I dont know.
View 5 RepliesConverted an VS 2003 VB Application to Visual Studio 2010. Conversion seemed to work great. Having trouble with the Backcolor of buttons. In design mode they are a light gray (I have them set to transperent and they are on a VBPowerPack.Blend Panel) - but in Runtime they turn the correct color (Steel Blue). How do I get design time to look the same as runtime? Also, they stay light grey in run time if I check Enable XP Styles. Makes me feel better to see the same colors at Design time
View 1 RepliesI 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.
I have a ComboBox control with some items added to the items collection in design mode. What I want is when an item is picked from the ComboBox a different value is actually used in the code, instead of what is displayed. I am aware of the DisplayMember & ValueMember properties, but I'm not sure if that is what I need to use. All the examples I found were for bound data.
View 3 RepliesI have a document with VBA controls in it that I created in MS Word 2003. After migrating to MS Word 2007, I get the message that "Can't exit design mode because control 'lblEmaillist' can not be created".
After reading through the various forums here and on microsoft.com it seems to be a known problem. I looked at these articles but am still having a bit of trouble...
[URL] refers to the same problem in word 2000 but after following the directions I still am getting the problem.
The problem does not occur when I open the document in MS Word 2007 or MS Word 2003. The problem only occurs when I open click on the link from IE.
I've set up the location as a trusted location in Office 2007 settings so that should not be an issue.
The document in question is being saved in the word 97-2003 format due to the fact that some people here have not upgraded to office 2007. I tried saving it as a .docm for office 2007 but the error message still came up.
Im using VS 2010 Trial edition. In my web application i got error "error hresult e_fail has been returned from a call to a component" while viewing the aspx page in design mode.
View 2 RepliesI know that there is no DESIGN, DESIGN_MODE, DESIGN_TIME, etc preprocessor directive value. However, I need something that can do the trick. I can't use a normal If statement, because in my case I need to change the inherited class so that the control renders properly at design time. If not, I'll receive an exception due to the fact that the inherited class is an abstract class.Here's what I'm looking to accomplish:
Partial Class MyCustomControl
#If DesignMode Then
Inherits UserControl
#Else
Inherits WidgetControl
#End If
I have opened an existing project and made changes in the design mode. (For example, I added a new button.) But when I tested the program using Start Debugger, none of my changes showed up.
View 1 RepliesSometime ago I used to create all my class structures in vision before I wrote them. That however didn't last. I found it easier to just make little drawings with pencil and piece of paper. And I still do to this day. In code usually those drawings manifest themselves as interfaces which then are implemented by different classes. I do all this in code. And I was just wondering if there is any tools available in Visual Studio for VB.NET that would allow to create interfaces and implement them in classes (which a lot of times means just adding variables to class that will hold data passed with interface attributes) from design mode(kinda like using Visio only after you finish you don't have to write out code).
View 3 RepliesI have an app that before it loads the form it uses Location to place the controls in the wright place.When it loads up I can see their original outline before they are displayed in their new location.So I have moved the the sub before the form load event but the result was the same.I also tried me.control.clear at the beginning of the formload.But I cant seam to find contrl property that allows to show all

The problem im having is that DotNetBar gets referenced fine and all the controls appear in the tab but when i drag one from the toolbox to the form it stays in the panel where usually the timers and other controls are..Example : Drag a ButtonX from DotNet toolbox tab and it goes to where timers and dialogs usually appear instead of on the form.The standard default controls work fine. But seeing as i already have 60-70% of my application done with DotNetBar controls, I am receiving errors like frmMain.chkboxx cannot be accessed as its private.I was working on my laptop and decided to install VS2010 to Desktop and Copy/Paste the whole project folder over and this happens (I can still open the project on the laptop fine and DoTNetBar works)[code]
View 16 RepliesI've been building controls for many years professionally and personally, but even back in VB6 days I just could not work this out.

View 1 RepliesI have a couple of user controls, which I show in my main form.
So let's say here's what i want:
Sub Show_Control1()
UserControl1.Show
'CODE TO HIDE EVERY OTHER DISPLAYED USER CONTROL ON THE MAIN FORM
End sub
Right now I have to hide them one by one with hide, because I don't know what's the current displayed form.
How can I basically lock a default property so the user cannot edit it? For example, if I wanted to lock the BackColor property, how can I make it so the end user of the control can't edit it?
