Visual Studio :: How Does The .net Framework Nest Forms In Classes
Sep 11, 2009
If I look at some classes in the framework, using reflector, I can see that forms and user controls are made private and nested into a parent class.For instance, I have a control which makes use of pop-up form that is specific to that control.At the moment, I make the pop-up form friend accessible.If I wanted to do it the framework way, I'd make it private and nest it into the control class.If I do this, however, I can no longer use the ide to design the form and I get errors when I try to compile.

I'm using visual studio 2008 SP1, I'm working with a web project in VB.NET. The problem when I add new class file (of-course in App_Code) it doesn't recognize it. all the old class files are working fine, but the new ones aren't. I restarted my computer and still the same problem.

I'm running Visual Studio 2010 with the Dot Net 4.0 Framework. I've been running around everywhere looking for the answer and haven't found anything. All I want to do is be able to access the Tags and Comments of an image file through my code. I've tried a bunch of different things but to no avail.
Dim dra As IO.FileInfo
My.Settings.Properties.ToString()'didn't work
dra.Attributes.ToString()'didn't work
IO.File.GetAttributes(fullPathFile)'didn't work
[code].....
And a bunch of others that I don't feel like undoing to.

I am very new to this whole programming thing and I have read several books and many websites but I can't get a good start on creating a video poker game. I understand that I need to create classes, but have no idea how to start. Most of the things I have been reading have been for Visual Basic 6.0 and it appears hard to understand. I am looking for some type of tutorial of how to create the classes I need and how to get the actual information from the classes into my form. Can anyone out there provide me with a good starting point? Is there any good (and easy) code out there to get me started. I feel that if I can get a good starting base, I can learn from there.

I created a VB Console app and it defaulted to .NET 4 but I need it to be .NET 3.5. I've been looking but all the references I find say to change it on the 'Compile' tab in properties but I don't have a compile tab or anything else that lets me change the target framework.
Note: I'm using VS2010 Ultimate

My VB project is large enough that it requires several files. It was originally developed as a Console App and I created each file as a MODULE. All modules could use subroutines, data structures and constants from other MODULES and everything worked fine. I needed to add basic windowing to the app and this required that the app be converted from a Console App to a Windows Forms App. The main window is Form1 which is not a MODULE but a CLASS. The problem is that some MODULE based functions cannot access subroutines, data and constants that are defined within the CLASS Form1 unless they are incorporated into the CLASS file and this makes the CLASS file very large. If I add a new Class file to the project, it also cannot interoperate with Class Form1 in the same way that multi-MODULE code interoperates.
How does one spread CLASS code across several files and still allow it to interoperate as if it were in a single file? Alternatively, how does one create several CLASS files that operate the way multiple MODULE files operate.I am sure that there are all kinds of best practices that I am violating but the goal to to get some prototype software working and interfaced to some lab equipment.

Is there any predefined property by which I can set the DisplayFormat/DisplayStyle of a textbox? Suppose I want a textbox to hold the actual value 888888888888.88 and show it formatted as 888,888,888,888.88. In short it should hold 'Double' data type value and show it with thousand separators and decimal places upto two digits. If text is cleared from the textbox, it should have 0 as value and 0.00 as displayed value. Also the number of digits in the textbox may vary accordingly. So how can it be done?

I want to download xsd specifications from a web service and automatic converting (serialize) these schemas to classes (visual studio - vb.net). If the organization that is responsible for the xsd schemas alter them in a way that only my class corresponding to the xsd have to be altered (not the rest of my code) I would like to automatic update my xsd corresponding class.
I use vs2010. What I want to do is: call a web service where I can send in an input parameter to the service which specifies the xsd I want to retrieve (the service is GetShemaDefenition and returns an object with the schema specification in a string property of the object). I den have to read the xsd string from the string property and convert this to a class representation of this xsd specification. Is it possible to do this automatically? I have done this manually by using xsd.exe. If the owner organization of the xsd has altered the xsd specification, I have to test if there is a new specification, and if there is I have to build a new class representation of this xsd? Is it possible to do what I want? And how would I know if it has been a big change in the xsd which also affect other parts of my code, not just the class representation of the xsd?
Update:I use one web service where one of the properties is a string. The string is an XML inside a CDATA block. The organization which provides the web service will not pares the xml inside the CDATA block but instead forward this to another organization that will use the xml data. The organization which uses the xml data specifies the xsd schem that I have to follow to generate my xml correct. This is the xsd schema I can get from another web service. I don't really understand what I can do with this xsd file from the web service. What can I do with it and why do I want to download it from the web service, when I can't use it automatically? Because I have to manually do the changes when the xsd changes I can easily download the xsd schema from the organization's home page and make the new class with xsd.exe.

The company has been using Visual Studio 2008 and .NET Framework 2.0 for approximately 2 years. During that time we released several versions (4.x.x) of our program to the public and were able to preserve the user's settings using My.Settings.Upgrade.During the past development cycle we upgraded the program to Visual Studio 2010 and .NET Framework 4.0 and changed the version to 5.x.x. Now, when a user upgrades from 4.x.x to 5.x.x they lose all of their settings.However, in all upgrades after that point (ie 5.0 to 5.1) all the user's settings are once again preserved.I checked C:Documents and Settings<USER_NAME>Local SettingsApplication DataCompanyName and it contains two directories:
ApplicationName_Url_aaa ApplicationName_Url_bbb
where aaa and bbb are 32 character strings. All of the user.config files for the 4.x.x releases can be found in the ApplicationName_ Url_aaa directory. All of the user.config files for the 5.x.x releases can be found in the ApplicationName_Url_bbb directory.Based on this information it seems like something changed when we converted our program to VS2010 and Framework4 that is now causing a different 32 character string to be generated. However, we have been unable to track it down.

I realize this post is rather long, but I wanted to give all the information up front instead of people having to ask me for more information.At the end of the re-installation of Visual Studio 2008, there is this message:
"Microsoft SQL Publishing Wizard: [2] Error: Installation failed for component Microsoft SQL Publishing Wizard. MSI returned error code 1638" in the log file dd_error_vs_procore_90.txt.
I have searched on Google for this whole message and found some references to this error, but I have done what they said worked for them and it did not fix the problem for me.When I searched for just "MSI returned error code 1638", I got that it cannot install something because it is already installed:"Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel".In Add/Remove Programs I see these two programs:
Microsoft SQL Server Database Publishing Wizard 1.3
Microsoft SQL Server Database Publishing Wizard 1.4
Are these programs/versions what the error is refering to? Am I safe to remove them and depend on the similarly-named item which would be newly installed with Visual Studio 2008 - "Microsoft SQL Publishing Wizard"? I still use SQL Server 2000 and 2005 on my computer, as well as 2008. I had installed VS 2008 on my computer before without this problem and also have VS 2005 and 2010.

I am programming in VB9 WPF and Blend 3. I was working on a program in Blend 3; I can work on all my forms and everything runs fine in Blend, but when I opened it in VS the WFP forms would not display (I have five of them in my program and they all have the same problem in Visual Studio.), but I can run the program in VS, see the forms in run mode, and work on the code behind with no problem. I can't determine what is causing the WPF forms error in VS. It appears I have a "ResourceDictionary_4 error, but I cannot locate that dictionary in either Visual Studio or Blend. I even tried searching my entire computer and can't find any trace of it. Are there any ideas as to how do I solve this problem? The error messages I am getting are:

I am trying to make a UI that has a few forms / panels, each for a different "Tab" in the program.
I am guessing that the way to do this is using panels and code like:
Panel1.Visible = False
Panel2.Visible = False
Panel3.Visible = False
Panel4.Visible = True
Would I be correct in assuming that this is the best way to go? (I don't want lots of popup forms in the program, looking for the most streamlined way to go).
Also, if this is the correct way to go how would I go about hiding each panel in the IDE so that I can work on each one seperately using the designer view?
Here is the best example application I can think to use: [URL] Each of the tabs (Proxies, Harvester etc) has an image as the tab (Which I can't find an option to do with TabControl and then displays the container / panel below it

A Dialog that is added to a Windows Forms project comes with two buttons (OK and Cancel) and Click event subroutines for each. The subroutines close the Dialog with different DialogResult enumerations. Here's the code in the one for Cancel: Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Close() But either statement (changing DialogResult to an enumeration other than Null or Close), by itself, will close the Dialog as well. (Try commenting out one and then the other to prove it to yourself.) Here's the question: Why both? Why not just one or the other?

Today I noticed that Visual Studio 2008 always treats a file as if it was a component or a form if this file contains a definition of one.This means that it always opens the designer by default. I think this behavior is very annoying, because a file containing a class that derives from form or control does not have to be an actual form or control and I want to edit the source by default.

With 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?
