I have no idea what I have done wrong here, so I'll just attach my project as a zip file and see if any of you are kind enough to look into it for me.I am reasonably experienced in C#.NET but having trouble using VB.NET for a school assignment.I cannot open half of my forms in designer view because "To prevent possible data loss before loading the designer, the following errors must be resolved".
View 1 RepliesIf I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?
i was doing a fair amount of programming many years ago, like 10 it feels like, so I'm sorely not up to date on how my newly downloaded Visual Basic Express expects me to communicate with it.I am writing a program that pulls a cell from a database after the user has gone through several forms to determine which cells they want. When I write it like that, it doesn't sound very efficient, but I've designed it this way for usability.Here's where I have a problem: Should I store the path the user takes in a string, an array, what?
Here's an example:Someone wants baseball stats and trivia. They run my program, main form pops up, they select National League button, the NL Form pops up. Now the way my program is set up right now, is there are two ListBoxes on the form, one is populated, and as the user selects a Team from ListBox1, it jumps to ListBox2. Once they've selected all the teams they want info for, they click a button Next.
What I now need the program to do is show the next form "Team: name" once for each team, and insert the name of the team on the form in the appropriate label which I'll have blank. This form will also do the Listbox thing except the first listbox will populated with Topics like HR Stats, Pitching Stats, Coach History, etc.
When I open VB projects in Visual Studio 2005 and attempt to view a form view designer I have started getting "File Download - Security Warning" Message prompting a .tmp file in the location of my project. If I close all open designers and rebuild the project I am then able to open the designers OK.I saw a suggestion to 'restore file associations' in Visual Studio and tried this but with no success.
View 1 RepliesI have two forms frmMain and frmNew, and one module modMain. In modMain I hold public variables which are needed for application. My question is how to open and close those two forms when needed? I ask this because if i set frmMain as startup form, then when closed, application will end, and one of those two forms will always be displayed. Also if I set frmNew as startup form, then when I close this form, application will also end. Is there a way to do this from module or something so my application won't end after closing and opening any of those two forms?

View 3 RepliesWe've recently upgraded from VS2008 to VS2010. The conversion of our vb.net 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.

I would like my forms to open as part of a "bigger" program, where there is a screen that fills the monitor and inside this screen is my form, centered. When a new form is opened, only the new form will be displayed...it will not be form on top of form.It would look similar to the screen in the following link, except the form inside the bigger screen would not have the minimize, maximize, or close buttons.I am just wondering if there is a property in VB.NET forms that will allow this to happen.
View 8 RepliesWith several forms of mine, I occasionally run into the following issue: I edit the form using the designer (Visual Studio 2008, Windows Forms, .NET 2.0, VB.NET) to add components, only to find out later that some minor adjustments were made (e.g. the form's size is suddenly changed by a few pixels), and controls get deleted. This happens silently — event-handling methods automatically have their Handles suffix removed, too, so they never get called, and there's no compiler error. I only notice much later or not at all, because I'm working on a different area in the form.
As an example, I have a form with a SplitContainer containing an Infragistics UltraListView to the left, and an UltraTabControl to the right. I added a new tab, and controls within, and they worked fine. I later on found out that the list view's scrollbar was suddenly invisible, due to its size being off, and at least one control was removed from a different tab that I hadn't been working on.
Is this a known issue with the WinForms Designer, or with Infragistics? I use version control, of course, so I can compare the changes and merge the deleted code back in, but it's a tedious process that shouldn't be necessary. Are there ways to avoid this? Is there a good reason for this to occur?
One clue is that the control that was removed may have code (such as a Load event handler) that expects to be run in run time, not design time, and may be throwing an exception. Could this cause Visual Studio to remove the control?
I have created a custom designer (PannelloSfondoDesigner) for my custom control, a background panel (PannelloSfondo).
<Designer(GetType(PannelloSfondo.PannelloSfondoDesigner))>
Public Class PannelloSfondo
Inherits UserControl
[code]....
It works, I click the little arrow, the context menu appears:I click the menu item, the event is fired, the control is docked:but the menu description is not updated or refreshed (it should show "Undock from parent container"). Then if I click outside the control to deselect it and then I click back on the arrow to show the menu, the right menu item is displayed:How do I refresh the menu items?
I am desinging a form with mutiple controls on a tab page control and was moving controls between tab pages by cutting and pasting them. The forms designer obviously got confused at some stage and I now have controls that are declared in the designer.vb but do not appear anywhere on the form.
I can't even rename the controls that are there which have been given generic names to the names I want because they apparently already exist. I realise I could edit the designer.vb and remove the references to these controls but that seems fraught with danger?
I am using the following code in the 'Application.Designer.vb' to set one of the two forms as the the mainform for my splash screen.The global string array gSetupStr(0,1) only produces a correct result when any Msgbox is inserted before the 'If' statement.However,I do not want the Msgbox during a splash screen, but do want to control the mainform.

View 1 RepliesIn a windows forms class in Visual Basic 2008, there are several horizontal lines created with the lineshape control dragged from the toolbox. A very strange thing is happening with the horizontal lines. In the forms designer, all of the the lines (both horizontal and vertical) look fine, but when the program is executed (in debug mode), about 3 seconds after painting the screen nicely, I get echos of portions of the horizontal lines about 50px or so above my horizontal lines. You can look at the screenshot here: [URL]
View 17 RepliesWhen I develop a Windows Forms app in Visual Studio using C#, every control that I add to my form is by default marked as private, which is what I want.
When using VB.NET, every control is by default marked as Friend (the equivalent of internal in C#), which is not what I want.
Can I just change this default? It seems like surely it's a setting somewhere.
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.

View 14 RepliesI'm in the process of adding EMR (Electronic Medical records) to my app. We have many PDF files that where created in Adobe LiveCycle and Acrobat Pro. Not sure if this is possible, but what I'd like to do is open a PDF file within my app and display it for the user to fillin the PDF form. Once PDF is filled in, I'd like to be notified (user clicks submit) when user is done, then get data out of PDF and save it to database. Or be able to fill in a PDF automatically and then display it to the user for editing. I know there are many tools out there to create/edit pdf files. The Acrobat SDK also includes a PDF viewer control, but the problem with this control is there is no way (I've found) to also edit the file through my program because the control don't expose the AcroForm class through the control. BTW, it this can be done PLEASE let me know how. Also note that most of these are dynamic PDF files (created in LiveCycle) and some of the third party tools don't provide support for these files.
I don't care if Acrobat reader is required to be installed on the user computer, I just need to be able to get some type of notification that the user is done filling in the forms. It might have been easier to just create a winform and with all required fields, but a lot of our users are not computer savy, and have been using the paper version of the PDF files for a while. I need to make it as easy as possible for them to jump in and start using the program, hince embedding the PDF into my app.
Wondering what is the best method of viewing a pdf, and adding text to the pdf, then printing it out? Currently, I opened the pdf in Photoshop, saved it as a bitmap, made it the background image on a form, overlayed it with labels, and am using the form.print method. This isnt exactly the best way to do this. Does anyone else have any good suggestions (without spending more than say $40)?
Project Background:
I work for an aircraft manufacturer/maintainer, and every time we have a broken/removed part, I have to log into our part logistics website, then hand write a form with all the installed and broken parts info (a full page). My program parses all the necessary info from the website, then loads it into textboxes (to be modified if needed) which are then copied into the labels overlaying the image of the form I have to fill out.
I want to build a form with fields bound to a datasoruce that the user can scroll through (using the up and down arrows).This would be a detail screen, but I don't really want a visible data gird or list on the screen with it, but as I'm still designing this may be something I would want to try also. The screen would be read-only data with a search textbox that would be used to query the list of data. The user will enter a search term and then browse through the detail screen to locate the exact record they want. I'm somewhat restricted on design because I'm trying to replicate a legacy program and don't want to deviate too far from the original design.For my datasource I've got a List (of MyClass), I just need to figure out the binding and navigation.
