View 2 RepliesI want to be able to incorporate some constant definitions and enum types in multiple classes of mine.Something akin to including a header file in C++. How do I do this best in VB.NET? I'm having a hard time because the only way I can see to do it is to inherit a class with the definitions in it but there is no multiple inheritance in vb.net so I am having some issues with that.
View 6 RepliesI added a table to my program and it generated two errors and not it will not build. I have added quite a few tables and this has never happened before. The reeors are:
1. public sub new ' has multiple definitions with identical signatures
2. 'Protected Overrides Sub OnCreateMainForm()' has multiple definitions with identical signatures.
I have deleted the table that I added and tried undoing everything having to do with it but nothing works.

View 2 RepliesI have a user control which consists of a dataviewgrid with some extra panels controls etc.I have just updated this program from an old version of vb where the tab control was just a row of tabs with no actual child pages attached.so to use several of these userControls (called 'Pages' from now on) a Panel was created and placed underneath the tabs to give the illusion of tabpages.when a user clicked a tab the relevant 'Page' was brought to the top of the Z order. This was accomplished with a directory of the 'Pages'..This all worked fine until I decided to change to using the TabControl in VS 2010.
So I didn't need the Panel anymore I just added the 'Pages' to the TabPages instead and I could also get rid of the directory to access the pages as it is not needed for display purposes anymore and for other access I could use the Tabcontrol.TabPages collection instead.Now when each 'page' is created and setup the dataviewgrid is loaded with a Table and the columns are re-ordered.I am loading approx 20 'pages' to the tabcontrol 1 to each newly created tabpage obviously. this is done using using a for each loop from a DB table.now the problem is that the first 'page' dataview grid has the columns re-ordered but none of the others do ! the Data is fine it's just the column order that's wrong.the same code is used for all (The setup is method of the 'Page') and i have stepped through the code and it all works OK with no exceptions. no code is missed but the grid order is OK for the first 'page' but not the others.everything else works fine the 'Pages' are all on the TabPages and the data is OK..Now comes the really weird bit! if I add the 'page' to the old unused panel before i add it to the Tabpage all the grids are re-ordered fine as in [code] Now the Panel is visible but not on screen if you see what i mean obviously if i move it on screen it's empty as the 'page' control can only be in one place and it's on the Tabcontrol..so why is it working ONLY when I add it first to the unused Panel? what is happening here? Oh BTW it only works for this Panel - not if i create a new one and add it to that..AND if the Panel Visible property is set to false the columns are not re-ordered again? I have tried deleting the panel and all code that uses it but the grids are not ordered properly till i re-instate the panel?
I'm building an application that is intended to function off and online using the new Local Database Cache functionality included with Visual Studio 2008. My issue however does not pertain to that directly, as I have a pretty good understanding of how to use it and how it functions. My issue is with getting an understanding on how to directly write to a SQL database.
Most of the tutorials, videos and education available when it comes to databinding makes the assumption that I need my application to pull data and edit it, but in my case all I really need (in fact intentionally all I want) is for the application on Submit to write data that it pulls from the form as a new record in a SQL table.
Here is what the program looks like now.
Public Class StatCom
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code].....
At the moment the program simply does a status check for connectivity and wether it can ping the server (in this case the SQL server) for the purpose of displaying a online or offline status in the form.
I follow it up by making the status checks.
Finally I declare all the various fields I want to capture and write to the database.
What I want to do now is have a SUBMIT button that on click takes all the data in the form and writes a new record to the database I have already setup and have data connection to.
I know that the code has to be written using the .recordset functionality, but I haven't found any could tutorials on the subject that have turned on the light upstairs.

View 11 RepliesI have a datagridview that is scrollable due to number of columns necessary.When I edit a cell, I display a multi-column listview that shows the item that will fill the cell in the first column and some form of description or other information in the second and sometimes third column (this should answer why I didn't use a combobox in the column in the first place).When I display the listview, when I scroll the datagridview, the listview stays put (as is the obvious). Is there a method to anchor, for want of whatever the proper term is, the listview object to the datagridview cell associated with it so when I scroll, the listview also moves? Or do you have to do calculations and adjust the positioning and repaint the object?
View 1 RepliesI'm not positive I'm going about this the right way. I've got a suite of applications that have varying types of output (custom defined types).For example, I might have a type called Widget:
Class Widget
Public name as String
End Class
Throughout the course of operation, when a user experiences a certain condition, the application will take that output instance of widget that user received, serialize it, and log it to the database noting the name of the type.
Now, I have other applications that do something similar, but instead of dealing with Widget, it could be some totally random other type with different attributes, but again I serialize the instance, log it to the db, and note the name of the type. I have maybe a half dozen different types and don't anticipate too many additional ones in the future.
After all this is said and done, I have an admin interface that looks through these logs, and has the ability for the user to view the contents of this data thats been logged. The Admin app has a reference to all the types involved, and with some basic switch case logic hinged upon the name of the type, will cast it into their original types, and pass it on to some handlers that have basic display logic to spit the data back out in a readable format (one display handler for each type)NOW... all this is well and good...Until one day, my model changed. The Widget class now has deprecated the name attribute and added on a bunch of other attributes. I will of course get type mismatches in the admin side when I try to reconstitute this data.
I was wondering if there was some way, at runtime, i could perhaps reflect through my code and get a snapshot of the type definition at that precise moment, serialize it, and store it along with the data so that I could somehow use this to reconstitute it in the future?

View 1 RepliesI was wondering if there is a way to take an object in Visual Basic 2010 (Express, FWIW) and browse through its structure to visualize how the data inside is laid out.For example, I have an object called "model" that is populated by a function that is a black box to me. Model is set by a "read" function that loads a DXF file from disk. The read function isn't very well-documented.
What I've discovered is that model.Entities ends up containing a list of different objects, all with different properties. I'd like to be able to simply browse this list of objects and view their associated properties and values at run-time, similar to how you can use Intellisense to view a list simply by typing "blah." and waiting for the pop-up to appear.A tree view that you can pop open and closed would be excellent. Obviously this has to work during run-time rather than in the editor because the file hasn't been loaded if the program isn't running.
Is this something that's possible in Visual Basic 2010? Is it a built-in feature I can't find?
I am using Visual Web Developer 2008 Express and making a Webform. I want to arrange my labels and drop down listboxes in a table to keep them together on the form in a neatly manner. If I use the 'ToolBox' on the side and drag a HTML table to the workspace I get a nicely formatted table with 3 rows and 3 columns. And I can drag and drop my labels/listboxes into these columns and all is fine and good.
If I use the 'ToolBox' and drag a ASP.Net table to the workspace it starts as just a boarder with '###' inside of it, which I cannot drap and drop controls into. I'm not sure how to place controls into it. I figured out that you can add the Rows - then Columns in the properties window, but that just adds more cells which have the '###' in them. I can make it work with the HTML table, but I just want to know if I can do the same with the ASP.net table.
Just say i have:

What I want to do is replace the old style with the new style in a few file. Since Visual Studio's find and replace tool allows you to do regular expressions, I assume there must be an expression I can use to do this conversion.
way that I can create a program that has the ability to check spelling that are being entered by a user or even displays a definition of a word? For example, when a user keys in a word in textbox then displays a definition into another tetbox but the main concern here is the source of the definition. Of course, it would be a very long task if i would manually encode words and their definitions in a database and retrieve them. I mean, can I just retrieve definition from a dictionary source, like maybe
View 1 RepliesThe situation is that I have a menu strip on the form from which the user can select an item, which opens a sub-menu, which opens another sub-menu which contains a combo box listing some options.
Eg. File>Project>Load>combo-box control
When the item is selected in the combo box, the code executes and modifies values on the same form, but the menu system does not collapse by itself.
I have to click on the form and then the menu system collapses.
I tried setting the focus to the form, but that does not collapse the menu system.
Does anyone know how to get the menus to collapse automatically?

View 8 RepliesI have a block of related sub routines I would like to "group" together within class to make navigating a littel easier. When I say group, I mean achieve the same functionality of being able collapse and expand a block of code as would with single procedure or class. Two alternative ways I can think to accomplish this is either use a partial class for those procedures or use namespace. I just wanted to see if VS for VB.Net had another way to be able group and collapse blocks of procedures.
