Program 2008 Form Is Corrupt And Can't Be Loaded By Designer
Mar 4, 2009
I have coded in the older version of VB for years (VB6 and prior) and Recently I just began learning VB 2008. In my current project I made a mistake in a form name frmAuthors and so far I am unable to recover. The problem is that I tried to have the form inherit a class I had created (first mistake). The IDE generated a popup message stating the error and provided the option of changing from inheritance from system.windows.forms to the class I had created. I said yes just to see what would happen (I was bored so I was up for something new) and that's when the form got corrupted.Is there a way to let frmAuthors go back to recognizing itself as a form object and not a member of the object I had created?

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?

My company's main software package includes a hefty configuration library which loads on startup. This config library includes some mandatory settings which, if not supplied (via command line arguments), cause the entire application to exit.
This has never been an issue for our users, who launch the software via scripts which have the needed command line arguments supplied automatically. But sometimes when debugging our software we developers forget to specify the necessary arguments in Visual Studio's debug options; it's then very annoying to be greeted with the message Config specification invalid -- missing required parameters X, Y, and Z -- shutting down (I'm paraphrasing, of course).[code]...

I have a very simple form with a combo box named txtRoomType bound to ROOMCODESBINDINGSOURCE and a DGV bound using ROOMPRICINGBINDINGSOURCE.
Public Class frmShowRoomPricing
Private Sub frmShowRoomPricing_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code]....
When I check the value of txtRoomCode when the form is loaded for a 2nd time it tells me it is blank, but there is a value in it. I think the fault is in the form_load, but I do not know why.

Is it possible in VB .NET to find out if a form is loaded? Also, is it possible to find out if a form is shown at the moment? I think for the second issue it's enough to get the value of the property of the form:
MyForm.Visible
However, I don't know how I could find out if a form is loaded or not.

Is it possible to run a function or to execute a button just after the form was loaded? I mean to execute it just as the form_load subroutine has ended, so the form is already being displayed.

I have a Parent form that loads a child form and I only want to allow one instance of the child form. I have this on the button to open the form. Stepping through the code with the debugger it "appears" to work OK when the form is open (I say appears because nothing changes) but when the form is closed it doesn't open as I would expect. What am I missing?

In VB6 IDE if you doubleclick on the titlebar of the form designer, it maximizes/restores. But in VB.net it opens up code window.How do you quickly maximize/restore the form designer window ?

I keep getting the following error in XP only (not Vista or Windows 7) Attempted to read or write protected memory. This is often an indication that other memory is corrupt The interesting thing is that the error is on a line that basically just creates a bitmap:
vb
Dim B as New Bitmap(400, 300)
This is in a timer and doesn't always happen the same time - eg sometimes it happens in 2 seconds sometimes it gets to 10 seconds - the interval is 50ms?

Ok I have a project which has a MDI parent. Inside the parent I have multiple isntances of a form load(frmLine1t5). When my program loads it will load a different form(frmSelect) and if I manually load a different form(frmRetests) I can put frmSelect on top of frmRetests and bring one another to the front if it's clicked on(without using the bringtofront method)However as soon as I load a single instance of frmLine1t5 I immediately can no longer bring ANY form loaded into the MDI parent(before or after frmLine1t5 has loaded) to the front. I can only bring them to print IF I use .bringtofront method

I�ve had a problem iwht my app for some time now. It�s very slow and above all it takes forever to startup. I�ve been adressing som issues that has to do with the database behind it.Recently I noticed that the app is starting an instance of excel, which seems to be what�s taking it so long in the starting process. The app is using access as db, and the db has some linked excelsheets. The app is also running some code in excel, but it�s starting, and terrminating, separate instances for that.The linked excelsheets are also "live-linked" to another app (third party), fetching real time data via DDE I think.

I have a single user app that I wrote and have been using for more than a year that uses an Access 2003 database. Today, out of the blue, I started getting a DB concurrency violation whenever I tried to update one particular table in the database. After trying to troubleshoot what the problem might be, I just deleted that table and recreated it and the problem went away.

In properites>Application>"Startup form" combobox, in my VS VB.NET project, I see only 2 forms listed, while my application has 6 forms. Does this mean something is corrupt? I tried to make a new project, then copy only the old vb files into this new project. But still only those two (of 6) forms show up in the "Startup form" combo box.

I have a program I've been working on for some time now and I'd like to try to streamline it somewhat. I have a main menu form that has a split panel, in the left panel is a treeview that displays forms you can open and when one is selected, it opens in a child window in the right panel. Each time I open form I called DWNForm, it does a series of dataset loads which are the populating items for a series of listviews.
What I would like to do is have these datasets load once during the mainMenu load and then have the DWNForm be able to access the datasets once it is called from the treeview selection.

I cannot use Visual Basic 2008 at all. When I go to "new project" and choose "Windows Form Application" I get this error.I have tried multiple uninstall/reinstall with no result.A microsoft reply to this suggested that I needed: " .NET Framework 2.0 Service Pack 1 " I checked, and I did not have the .netframework 2.0 service Pack 1.
When I tried to download and install the above from Microsoft.com, the istaller said that "it was not allowsed" and I was not able to install the service pack 1.
I tried Uninstalling net framework 3.5, 3.0, 2.0 and then reinstalling .netframework 2.0 sevice pack 1; then reinstalling Visual basic 2008 express edition. At the reinstall of Visual basic 2008, .netframework 2.0 sevice pack 1 is unistalled by .net framework service pack 2.When I check the foruims for simiar problems, the formus are mostly for Visual basic 5.0, or other programs that I do not have.
Here is the programs I have installed:
Operating system: Windows XP
Microsoft .net framework 1.1
Microsoft .NET framwork 1.1 Hotfix(KB928366)
Microsoft .Net Framework 2.0 Service Pack 2
[code]....
All the security updates and hotfixes for Widows XP.

I've been trying to figure out how to do this for some time now and keep coming up short, so I'm hoping to get some good suggestions.
I'm making an application that will allow the user to add some labels during runtime, edit their text, and then 'build' the designer that would output code for a scripting language.
The people using this app are creating the scripts using Notepad++ at the moment, but aren't developers in any way and would like an easier, point and click method.[code]...

I'm trying to make a list of flight plans loaded into my program, with each flight plan having a list of waypoints along the route, along with a few other properties associated with the flight plan. Each waypoint has its own associated properties, i.e. waypoint ID, waypoint type, location, etc.
Here's the declarations:
Code:
Public Class WPinfo
Public WPType As String
Public WPID As String
[Code]...
How do I implement the List methods to access the list elements, and add, remove, etc? The way I'm doing it now just gets me an 'Object reference not set to an instance of an object' error during runtime.
