Modify Designer.vb (form Designer) To Remove A DataSet Control From Winforms Windows?

Jan 27, 2011

I am attempting to update an existing winforms application, that was created with a dataset control on all the winforms pages. I have ported it from VS 2008 to VS 2010 and I need to update the database section and connect it to the SQL backend using traditional code method.In the Solution explorer, when I click on the Dataset files, and click "Exclude From project" I am unable to build the project.Is it advisable to comment out the code lines that refer to the dataset in the .designer.vb files?


DB/Reporting :: Changes To Typed Dataset Not Seen In Windows Form Designer?

Nov 19, 2008

I have a typed dataset with table adapters. I use this method because it makes it easier to design the layout of my DataGridView.The problem is I have added a new table to my dataset. When I go to the "Data Sources" list view, I can see the new table.However, if I add a new DataGridView to my form then attempt to bind it to my new data table, the table will not show up in the list of tables for that dataset.

Declare A WithEvents Class In Windows Form Designer Which Is Not Control Base

Jun 4, 2011

I am making a TabStrip control to hold a number of tabs just like TabControl, but only with the tabs, no page. The control has a "Tabs Collection", which stores a list of "Tab" class. "Tab" is not inherited from Control, but each tab has its events. So when the user add a "Tab" in the "Tabs Collection", each "Tab" instance should have a (Name) identifier, which user can access it in the code, and with WithEvents keyword so users can add event handlers to each "Tab". The expected out come should similar to this:

Friend TabStrip1 As TabStrip
Friend WithEvents t1 As Tab

Can't Find Windows Form Designer Code

Aug 25, 2010

On a recent project I stumbled across a page of code that looked unfamiliar, but which evidently was the code behind my form design. I'll copy and paste an excerpt to show you what I mean:

'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer


I thought this was a useful way to back up my project via email because it's in text form. But now I can't find the same information. I've looked in the Object Browser but couldn't find it anywhere. I think I stumbled on it the first time by right clicking Go to definition, but now that doesn't take me anywhere if I click on say form1. So where will I find this mysterious page that has all the form items information in text, not graphic form? Can't find it anywhere.

Windows Form Designer Generated Code?

Feb 20, 2009

Most of my project was imported from an older version of VB (now I'm using 2008). All of the forms had a "Windows Form Designer Generated Code" that I could expand at the top of the form's code. When I created a new form, that was not there, and I found out that in the solution explorer you can "view all files" and expand the form and look at MyForm.Designer and that has the same type of instantiation code. My question is, is there some way to update the old ones so they too do not have that "form designer generated code" at the top?

.net - Edit UserControl Subclass In Windows Form Designer?

Jul 1, 2011

In VS2010, targeting Framework 4.0, I have a UserControl which contains a TableLayoutPanel with an empty second row.Is it possible to add items to this second row using the Windows Forms Designer, or do I have to do it all via code?

EDIT: In reply to Hans Passant's comment, the linked question references a UserControl being used inside another control.I am asking a question about inherited controls.I have created the following test code, where TestControl is a UserControl containing a TableLayoutPanel named "TableLayoutPanel1":

Imports System.ComponentModel
Imports System.Windows.Forms.Design

creates a control which, when viewed in the designer, contained a TableLayoutPanel named "TableLayoutPanel1" which is not designer-editable.Creating a new UserControl, not inheriting from either of the previous UserControls, and then placing a TestControl into it creates an instance of TestControl with a Designer-editable TableLayoutPanel named "TestControl1.TableLayoutPanelX".Is there any way to make the TestInheritedControl class, shown above, Designer-editable?

VS 2008 Partial Class Files For Windows Forms Or Any Other Designer-generated Control?

Sep 24, 2009

I have cooked up my first iteration of a code generator which creates the basic Entity models from a SQL Database Schema. Currently, It will scan a SQL Db Schema, and create .vb code files complete with private members and Public property declarations for every User table in the Database. My next step is having it add the basic CRUD procedures as well. Are we mere mortals able to access whatever technology allows the Partial class files created by vs to be hidden/Linked to their "parent" files, such as the Partial Class files for Windows forms or any other designer-generated control? My thinking is that it would be handy to be able to re-generate code files from the database if necessary to reflect changes in the schema, without overwriting any other properties or methods added to a class in addition to those derived from the database. SO I am hoing I can have the Auto-generated output go to a Partial Class file, and then use a regular class file of the same name for the rest of the code. My Concern is the multiplicity of files that might result, so I was hoping it is possible to "tuck them in" to the parent code file in the Class View.

.net - Some Kind Of Error, Possibly When Viewing A Windows Form In The Designer?

Jun 24, 2009

I though I had solved this problem, but it is back:Code generation for property 'SelectedPeople' failed. Error was: 'Type 'ECS.Entities.Persistency.Person' in Assembly 'ECS, Version=, Culture=neutral, PublicKeyToken=null' is not marked as serializable.'The property on the error message is a List(Of Person) and for some reason it trigger this error, for almost anything I do, and its getting really anoying.Okanswering to the answers here is a little more information about the problem.

Yes it is during design time, it happens bascially anytime a open a form that has a UserControl that contains the Selected property in it, sometimes it happens even if I don't have focus on the form, also if I try to compile/run it happens and the message come in the form of a Message Box with just a OK, ECS.Entities.Persistency.Person is just a LINQ to SQL Generated Class, this should not matter at all to the problem, although I have added the attribute before the posting.he reason that this happens is because the Designer attempts to put the property on the Property Panel, and for that to happen, serialization happens.tryed to hide the property from the designer by using this attributes.

<DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _
<Browsable(False)> _
Public Property SelectedPeople() As List(Of Person)

C# Event Handlers Automatically Created By WinForms Designer?

Jun 18, 2010

Just moved from VB.NET to C#.In VB to connect and Event Handler to a Sub we use the Handles clause.From what it seems, this do not exist in C#. After creating a simple application with a button I realize that Window Forms Designer automatically created an EventHandler to my button1_Click function (after I double clicked it), in Form1.Designer.cs with this code:

this.button1.Click += new System.EventHandler(this.button1_Click);

But, in VB, the WinForms Designer create the Handles clause in my class, in the function header. So, C# create the default EventHandler in designer file, while VB creates in main class where control resides.

IDE :: DataSet Designer And Database Changes?

Oct 21, 2009

It seems that there is no way to preserve changes to a DataSet made with the Designer when there is a change to the database. The only way to get the Designer to rescan the database to incorporate a change is to delete the DataSet and then recreate it. This of course blows away all the mods you've made in the designer. There should be a way to have the Designer rescan the database while preserve all the mods that have been made in the Designer. Otherwise the Designer is essentially useless after the initial generation of code. What am I missing?

As a workaround, I tried incorporating the changes to the database by making the same change in the Designer rather than recreating. However, clearly no one tested this is it only partially regenerates the code based on the change. Try changing a field from nulls not allowed to allowed. This works when you add data to the DataTable, but bombs as soon as you update the database, because the DataSet code does and the database code doesn't get regenerated.

OutOfMemoryException With DataSet Designer

Jan 10, 2012

I have a windows form application made in Visual Studio 2010 SP1 Rel. I'm using SQL Server 2008 R2 for my database. I've been working on this project for a while now and I am almost completed with it. I recently had to add a field to one of my tables in my database, which hasn't given me much troubles in the past as I've had to do this before. To make sure I did it properly, I'll tell you how I added the field. I went to my database on my server and went to my table, tblOrderParts. I right clicked, and went to design. I added a field, Order_Delete, which I made a bit field so I could use a checkbox. When I went to my dataset designer, I used the wizard to add the field to the table in my program.

After I added it, I remembered that one of my forms was using a view I had created with that table that would need the checkbox as well, so I went back into SQL Sever to add that. Added in SQL with no problem, but when I went back to Visual Studio's dataset designer to add the field to my view, it won't allow me. I open the wizard, go to my view i created, vwAllOrders, and checked the box next to it. When I press Finish, though, I get, "An exception has occurred while attempting to set the data source generator property." I had to cancel out of the dataset wizard cause it wouldn't let me continue... even if nothing was changed.

Now it is also showing me an error in the Error section saying,
"Custom tool error: Failed to generate code. Exception of type 'System.OutOfMemory' was thrown."

Now that I've said the error, here's what I'm thinking is going on... Something must be wrong with the custom tool on my dataset. The tool name is MSDataSetGenerator. I went on more forums, and a couple mentioned trying to restart the custom tool by right clicking the dataset and going to "Run custom tool.' When I run it, it gives me another error. Not much different, but still different in wording.

The error it pops up say
"The custom tool 'MSDataGenerator' failed. Exception of type 'System.OutOfMemory' was thrown."

Changes To Dataset Are Not Appearing In .designer.vb File?

However, now when I open it in design view and add a new tableadapter I now cannot reference the new objects from the code. Likewise if I delete one of the existing tables in the dataset, it still appears to be there from the code (ie in intellisense)Similarly, when I examine the .xsd file, the changes I've made i the designer appear, but the changes are NOT happening in the dataset.designer.vb file. It's as if the two files are somehow out of sync

Dataset Designer - 'End Sub' Must Preceded By A Matching 'Sub'?

May 22, 2010

VB.Net 2010 Express - AMD Phenom II X4 - 8g ram There are times when I debug the app that I get the 'End Sub' must preceded by a matching 'Sub' error. This usually happens after I make a change to the table adapter query in the dataset using the designer.

If I dblclick on the error it opens the dataset.Designer.vb and shows the error in question.

First, I have made NO changes to this file manually Second, when looking at the code in question, it actually appears there is nothing wrong with it - yet the compiler thinks there is.

This appears to be a VB.Net 2010 IDE/compiler bug Now, I can resolve this error by re-opening the dataset, configure the Fill query, click Finish (not making any changes - just clicking Finish), and then save and close the dataset.The error goes away then, but I shouldent have to go through all that; especially since my query was fine to begin with.

Remove A Textbox In Designer When A Column Is Deleted From The Database

Aug 14, 2009

i am working on a Windows Forms application using It basically is an application made in vb 6.0 being upgraded to Now i have an idea but i am not sure if it exists.

Say i have a database (My_DB) and it has a table (item_details).

I wish to make dataentry into the elements of item_details table which currently has 6 fields. So i add 6 textboxes and 6 labels and make user enter them, one record at a time.

Say tomorrow i add or remove a field from the table item_details. I want such a mechanism where if the underlying table structure changes, the corresponding number of textboxes and labels must automatically change themselves. i.e. if i remove a column and now i have 5 columns, the form must also have 5 labels and 5 textboxes. Are there any controls to achieve this functionality. Am i talking MVC here?

VS 2010 - Remove TreeView ChildNode Image In Designer

Apr 23, 2011

I have a TreeView with several nodes that have child nodes. Whenever I create a child node, it sets the image to a seemingly random icon in my ImageList. There are a couple of properties for the TreeView that have this icon, but nothing happens when I change it to a different one. And besides, it won't let me set those properties to "None."

I tried look at the properties of the child nodes, but everything is set to none and nothing changes. Does anyone have any ideas? In the photo below, you'll see the Internet Explorer node and its child nodes that have the Chrome icon. I need the child nodes to be blank.

Control Properties Automatically Assigned Random Resource String Instead Of "" In Form Designer File?

Feb 8, 2011

The company has a Visual Studio 2010 Ultimate project that is written in Visual Basic.  The project has several strings in the resources file (Resources.resx).  One of those strings (VersionSuffix) contains "" when we are distributing a normal version of our product and "BETA" when we are distributing a beta version of our product.  Most of the time we distribute a normal version of our product.  Therefore, most of the time the resource string VersionSuffix contains "".

Recently, we attempted to distribute a beta version of our product.  Therefore, we changed resource string VersionSuffix from "" to "BETA".  However, it quickly became apparent that the resource string VersionSuffix was being used as the default value for several control properties in the form designer.  For example, if I draw a rich textbox on a form then file FORMNAME.Designer.vb will contain the following.

Me.RichTextBox1.Location = New System.Drawing.Point(286, 306)

Me.RichTextBox1.Name = "RichTextBox1"

Me.RichTextBox1.Size = New System.Drawing.Size(134, 33)

Me.RichTextBox1.TabIndex = 32

Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix

We are unable to find anything anywhere that indicates that this resource string should be used as the default value for control properties.  Therefore, we have no idea why this resource string is being used for this purpose.  We would like to change the control property assignments in the designer from Me.RichTextBox1.Text = Global.PROJECTNAME.My.Resources.Resources.VersionSuffix

Me.RichTextBox1.Text = "" However, we don't know why these strange assignments are being made.  Therefore, as soon as someone adds another control the problem will most likely return.  Does anyone know why this is happening and how to prevent it from happening again?

Windows Forms Designer Broken In VS2010?

Sep 3, 2010

We've recently upgraded from VS2008 to VS2010. The conversion of our Windows Forms app went well, but we're now having big problems with the forms designer.retty much any change to the layout of a form (sometimes just a solution rebuild) will work once, but on recompile, the IDE designer refuses to display the form, the error message being a null-reference exception (with no details as to what).Closing and restarting VS2010 will cure it, but only for one compile cycle - and it's obviously not practical to close and reopen every time. Closing and reopening the form does not fix it.
