I'm updating a large VB6 app to .Net. The database design will stay mainly the same but I'm considering making a few changes. The one I'm not sure of is if I should change how the "totalAcres" for a "User" is stored. This involves three tables(I'll only list the relevant fields),

View 1 RepliesI am writing a program which includes access to a Microsoft Accsess database. It is running fine on my work computer (windows xp) but when I transfer it to my laptop (windows 7) to work from home it stops running on the "open" statement. I have stripped out all other code so that I just have a program with this in:

Again this will run fine on my desk computer but will not get past the open statement on my laptop.Interestingly, if I start a brand new project on my laptop and paste this code into it - it runs correctly.

View 4 RepliesFirstly we need a deck object which in my case is a queue of type card. My question is relating to the card object.Would it be good programming to contain the card image within the card class so that the card object could be placed direct into some container or is it best to handle the card image within the main class.
View 4 RepliesIn an earlier post today [URL].. jmcilhinney in post #9 says,Quote: If you're going to use a DataSet at all then there's no reason not to use a typed DataSet. I would not recommend dragging items from the Data Sources window directly onto a form but that is not a requirement of using a Data Source.
I was wondering what is the down side of dragging items onto the form. I don't mind doing the manual programming, I would just like to know the reason I'm doing it.
This is kind of an off-the-wall question but does anyone know if VS 2010 has somekind of utility that will allow you to just drag & drop controls onto a form or something that will help in visual design. I'm just talking for visual purposes only. No code-behind files or anything...almost like a canvas where you can place controls and labels, etc.

View 13 RepliesI'm at a stage with my first real program where I'm putting some effort into the UI.I'd like to have a "meter", of "velocity" type, you know the ones in vehicles.I'm thinking of having an arrow that I've drawn in Illustrator pointing in a specific angles depending on values it gets from a database. i'm thinking of having on arrow pointing straight up, and two similar ones, only being diagonal in the picturebox (to the left and right respectively), thus enabling me to resize the picturebox and stretch the image. However that's not a pretty solution is it? Is there a way to place the arrow at an angle inside the picturebox, or the picturebox itself?

Ok that works, Now do I also need to include MyBase.OnResize(e), if yes then where do I add it?

View 8 RepliesI'm actually a beginner in VB express. i made about 10 easy programs, now i decided to make one a bit difficult. I'm stuck at the beginning.In first form i have 2 Textboxes and 1 Button (1username, 1password, button - sign in) and then another 2 Textboxes and 1Button (1username, 1password, button - register) I want to make something like this for beginning: When you register the infos from textboxes (username & password) are saved in some file (let's say in info.txt or info.ini). I actually want to know how to automatically save these usernames and passwords in text file when you click register button, so when you want to login, you have to use registered username&password. So if there in text file is not the username you registered or typed in textbox you can't login.

View 7 RepliesIs there a shortcut to get to the designview form in a winforms project in visual studio 2010.F7 will take you to code behind class form and shift + F7 will take you to design mode. Is there a shortcut to filename.designer.cs formWhere you have the control definitions, delegates (for click event etc). defined. I go to the form often if I change the name of click event etc.I have to go through solution explorer and click on the file. Is there a shortcut like F7 that opens the designer.cs file?

I was wondering if there is any advantage to do everything programmatically instead of using design view to create forms, controls etc. Would there be any difference in size and/or performance after you compile it? So far I've been doing pretty much everything programmatically, specifying all the properties that aren't default for my forms controls but I am starting to wonder is there are any advantages to this, apart from making it easier (sometime) to manage and change the behavior of my controls.

View 11 RepliesI am creating a UserControl with rich design-time support that should eventually look like the Options window in Visual Studio (or many other applications). Basically a split container, to the left is a TreeView with 'option categories', and each node in the treeview corresponds to a 'panel' to the right with certain options.
Just for terminology, the nodes in the TreeView are OptionsNode objects, the panels (containing the controls that determine the options) are OptionsPanel controls. My UserControl itself is called OptionsView and is the control that contains the treeview as well as a panel that contains the OptionsPanels.
I have some experience in design-time coding, and I have gotten pretty far. The OptionsView control contains a property Panels that returns the ControlCollection of the right side of the split container. The user can add/remove OptionsPanels via this property (and automatically an OptionsNode is created). The property uses a custom CollectionEditor that tells the designer to create instances of type OptionsPanel (instead of just Control which is the usual collection type of ControlCollection). Furthermore, in the CreateInstance method I use the DesignerHost object and its CreateComponent method to create the panels, instead of just creating New OptionsPanel objects. This way the OptionsPanel created is selectable and editable (via property grid) during design-time:
vb.net
Protected Overrides Function CreateInstance(ByVal itemType As System.Type) As Object
If itemType Is GetType(OptionsPanel) Then
[Code].....
In a typical session with the program I'm writing, the user needs to be able to access the data in 1 to 500 (maybe) tables (but always only one table at a time). Up to now I've been creating these single table datasets dynamically, as and when required.I've now come across the distinction between typed and untyped datasets (where typed seems to be the recommended option). It seems, though, that typed datasets are created at design time only and not dynamically. Is this correct? Are all of my dynamically created datasets therefore untyped?
