Run Different Code In VS Designer
Jan 9, 2012
I have a class that inherits the Windows Forms Combobox.The class should do extra work when items are added, but there is no such event.Therefore, I have added methods to add and clear items, which do the extra work.To avoid developers accessing the Items directly and adding to them, I have overloaded the Items property to throw an exception.This all works fine, except in the VS designer. The designer tries to access the Items property, gets the exception and shows an error.Is there a defined constant for when the VS designer compiles the code? This seems like it would be best suited to the task.

In my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?

I've been working on a project the last couple of day with the help of a lot of you out there. I've more or less finished the design of the interfase, but there are stange this happening with the form. I can say much about what is wrong because I dont understand it, but I would like to. I have added the form Class code and the Designer Code, is that enough or is more required? Theres a msgbox that popup in the form Load event which I placed there to see what I could learn about the GraphicsBuffer.
Imports System.Drawing
Imports System.Drawing.BufferedGraphics
Imports System.Drawing.BufferedGraphicsContext

I need some assistance again. In my previous posts, I asked about a good book to start learning how to us VB 2008.I had numerous replies, so I thought starting with Visual Basic 2008 would be a great start.As I am reading the book everything had mad sense up to Chapter 4. It's a simply program, and I thought I understood everything, until the middle of the chapter. So here's where I need help, and someone to explain my error.The author explains to place a Label & DateTimePicker onto the form, which I did. I renamed the label to NextWeek and DateTimePicker1 to DateChooser.Furthermore, I proceed to double click on DateChooser, which VB provides certain code automatically.[code]
After a few pages of reading, the author stated to put the following code under
Inherits class definition.[code]I went on and put the remainder of the code, which similar to the following:[code]The designer cannot process the code at line 51:Me. AutoScale Dimensions = New System.Drawing.SizseF(6.0!,13.0!)The code within the method 'Initilze Components' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.

but it's something I'm pretty consistently needing for the sake of my own sanity, so:If you add a Settings file to any project in Visual Studio, VS provides a GUI making it quick/easy to add a new Setting entry and assign it a Type; at that point the actual code-behind is automagically created with a variable and a property exposing that variable.Can we build our own designers to generate code this way, with a GUI allowing for those quick/easy variable/property assignments?

i have several forms in my solution that have listview controls and each of those listview controls uses the ListViewColumnSorter class that's provided on MSDN. This class requires a few lines of code in the Form_InitializeComponent Method of the Designer.Problem is, each time something on the form is changed, even if it's just a property of one of the controls, the designer deletes the code that I have for the listviews and I have to go back in and add it again.

Please can someone point me in the right direction? I would like to build my own code designer window similar to that of the one within the VB2010 IDE.I am not sure how to tackle this, at first I was thinking of using RichTextBox as this can accommodate the fonts and colors.
An example of what I am trying to achieve.Should be able to outline, expand and colapse based on my own tags. e.g. in the VB.Net IDE a function and end function are tags that would produce an outline
Should be able to change color of text based on characters. e.g. ' would turn green in the VB.Net ide as it is a comment Should be able to indent based on specific tags. e.g. With - End with would auto indent within the VB.Net ide
I should be able to cover the text color and indents using RichTextBox, but I am struggling with the outline expand and colapse.The purpose of the project is to build a simple interface for creating config files that use only specific tags

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
[code]....
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.

Just wanted to know if you had some design code which was created, and that is all you have. Can you open this designer code and create the actual working main Form from this? I don't need this designer code for any specific task, just wanted to know if there is a command within VB Studio 2010 that creates the actual Form from the design code. For example; The following piece of designer code is for a simple program that finds the Circumference of a Circle.

I was working on my project (creating a new form), and when I switched from the code view back to the designer view, I got the following error:
The designer cannot process the code at line 118: Me.VDARSQLDATASET = New Veterinary_Digital_Anesthesia_Records.VDARSQLDATASET() The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified. Please remove any changes and try opening the designer again.I am now getting this error on every page. This project has been working for months just fine, but for some reason the VDARSQLDATASET has dissapeared- kind of. I can still access the dataset (the file is still there), I just can't reference it in the code (intellisense can't find it).

I am creating a VB.NET (2005) GUI that uses several controls embedded into tab pages.When VB.NET autocompiles (if I switch windows) it adds lines of code to the .Designer file that causes errors:Windows' is not a member of 'System.Windows.Forms.TabPage'.is generated for:
Me.tbRxMinValidBits.TextAlign =

What is a standard way to open the Designer (automatically generated) code for a VB file?
As a workaround, I can get to it by searching the entire solution for some keyword that is usually only found in those files: Global, Partial, etc.

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?

I am using 2010 express, and when I try to use it to open a program that I had made with 2008, it will open and it will allow me to debug the program, but neither the designer nor the code will show. It is just an empty space in the middle of the screen.

So I've created a very simple UserControl that is pretty much just a combo box that has US States in it and a couple properties to return the selected value as an enumeration or a string, etc.The enumeration and string values I'm using are being referenced from an external library which is working. However, when I add my user control to another project the designer-generated code has errors in it. [code] I would assume that this probably has something to do with project settings or something similar for the user control. The control itself is in a separate project and compiled as a .dll which has been added to my main project's toolbox and subsequently added to my form. [code]

I'm using a DataSet to interact with an accdb file in an application. While debugging, the app occasionally closes, without warning and returns the stack below. The code causing the exception is in the DataSet.Designer.vb file (automatically generated). What's curious is the line that reads:
If (previousConnectionState = Global.System.Data.ConnectionState.Closed) Thencommand.Connection.Close()End If Why would the code try to close an already closed connection?I just change the "=" to "<>"? Will it stick? (since it's auto-generated, I'm sure it will revert if I modify the dataset, right?)

I am working with Visual Studio Pro 2008, and trying to build a Visual Basic project for my College Course. The coursework is not my question, it's not difficult just time consuming. My problem appears to be much deeper, and is certainly causing me to take way more time than I should need to debug and completely random occurence. I don't mind posting the source code but it is rather vast, made up of 23 objects, each ranging from 200-700 lines. I am running Windows 7 Pro x64, and since I need Jet4.0 DB Engine or some such I had to set the compiler to target x86 CPUs. I have my suspicions, and as queried in my topic, I was wondering if VB Designer code can become corrupt or cause funky errors?
The layout I have is something like this:
frmMain
-frmCustomer
--frmAddCustomer
--frmUpdateCustomer
-frmContract
--frmAddContract
--frmUpdateContract
Each steps forward using the ShowDialog method. Initially I thought it was a fluke, but I had frmAddCustomer open and when I closed it (the code simply does me.close, nothing fancy), it jumped all the way back to frmMain, skipping frmCustomer. At first I was baffled, I spent some 45 minutes trying to figure out why. No errors or exceptions, so it didn't seem to be anything wrong really. Since I was building this project in stages I loaded the same form from a previous stage and copied/pasted the new code in. This seemed to fix it, but it happened again after coding for another 30 minutes to an hour. It also isn't limited to that form, I have now experienced the same issue with frmAddContract & frmUpdateContract.

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?
