I have a label that displays text kinda like a title to something (autosize = falseTextAlignment = MiddleCenter) and whenever the label control isn't wide enough to display the single line of text it tries to auto-wrap it causing half of the text to be chopped off at the top and half of it chopped off at the bottom. I would rather it stay on a single line and cut the text off from the right
View 1 RepliesI have a desktop WinForms app that I would like to be able to connect to my Sql Server database that I have through my GoDaddy webhost. Problem is not all ISP's forward the 1433 port (like mine) so I can't connect directly to the DB from any of my home computers without buying the expensive dedicated IP address package, which has me thinking since my website can connect directly to the DB I was wondering if it might be possible for me to make a dll that would have all of the database interaction through subs and functions and all my WinForms app would have to do is connect to that dll through http or something, anyone know if I could do something along those lines?
Reason for this is I would like other people to be able to connect to this database (the winforms app would have screens for creating and managing accounts, etc) without worrying about whether their ISP would block the DB port(s) it would just work.
We'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.

View 2 RepliesI have created a control, similar to an image combo, but a bit different. Any how, each of the labels that contians text to be clicked has an ID in their tag, that i wish to read. I have a sub routine called CBO_Click() which has the same arguments as a normal label click. How can i add the argument for the ID in the labels tag to be passed to this sub.
View 2 RepliesI want to read from a text file and display it in a label. However, when I do that, I see that there is no word wrapping. In the sense, a whole paragraph is displayed in one line and the next one in the next line and so on.

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.
View 1 RepliesI have a label in my form which displays the text-content stored in a text file. However it is not able to display special characters like ", ', : etc. Instead it just puts a small rectangular box (same size as that of the text).
How do I get them to display these characters? Should I not use text files in this case or do I have to turn on some control-properties?

View 4 RepliesI am currently helping to write a Visual Basics program that was originally writing with access.The Original Access program has been used and modified over the past 5 years, During that time the database has gotten pretty big.The problem I am having is If I add the entire database to my data sources it creates data tables for every Table and Stored procedure even when they are not currently used in the program resulting in a 20+ minute build time just to debug.I am currently only adding Tables and Stored Procedures as i need them, so its not that much of a problem now, but as I continue to work and add tables the build time is going to go back up, and Id hate to have to wait 20+ minutes to test a small tweak I made.
View 1 RepliesIf I create a new class library project in VB.NET, I can create subfolders (a la C#), add WinForm objects to these subfolders, and then specify a namespace:
Namespace Sub1.Sub2
Public Class SomeForm
Public Sub New()
InitializeComponent()
[code]...
This resolves as ProjectRootNamespace.Sub1.Sub2.SomeForm, which is good.However, if I create a new WinForms project in VB.NET, and attempt the same thing, I get this error in the designer:The class SomeForm can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again.Is there a way to have forms in sub-namespaces of a VB.NET WinForms app instead of in the root namespace?
I would like to open a new form from some other form, and pass some selected object from a control on that form to the new form. The sensible way to do this, I thought, was as a parameter to the forms constructor. Now I know that the visual studio GUI creates partial classes for my forms, that hold the properties that I can drag onto there in the designer. I assume it also holds a default constructor. Since it might do all sorts of stuff that is needed to initialise the form, I figured I should call it from my custom constructor ala
public sub new(byval my_parameter as Foo)
Me.new()
Me.my_parameter = my_parameter
[code].....
That clearly wasn't it, because it can't find a default constructor. The thing is, visual studio goes trough great lengths to prevent me from seeing the generated constructor, so I know how to access it. This leads me to believe that I am actually doing it wrong, and should have set out on some different path, as the path you are forced in to usually is the sensible thing to do, which I usualy find out way too late.
Is it better to use friend or public forms in vb.net? What are the advantages of each?I notice when you import a vb6 project, the forms come in as friend, but when you add a new form in vb.net it is public. I have not seen any difference in the way they work, though, so I must be missing something.
View 3 RepliesI have a very simple windows forms setup. Form1 has a progress bar and a button on it, when clicked the button opens Form2 which also has a button on it that launches Form3. On Form3 is a button which I want to use to raise an event back to Form1.To achieve this can I add an event handler on form1 that will listen for an event of the type raised in form3? Or do I have to pass references to form1 to form2 and then from form2 to form3?

I am retrofitting unit testing into a fairly complex system designed and written by other developers in VB.net. I am trying to develop unit tests for the GUI forms using NUnit and the NUnit Forms extension. (I've been looking at c# examples that are fairly easy to port over if you have a solution but don't know VB syntax as long as it uses NUnit classes)
I will try and explain what I am doing but first a brief description of the program. It basically monitors server activity. You need to connect to a server via a modal form with IP and Port fields(amongst others). Once you have connected to a server other parts of the program unlock and become usable (such as configuration of the server).
Desired process: Load program > click connect button > modal connect form loads > enter details > click OK to connect > main form updates to logged-in state > other functionality
The problem is that I cannot test the functionality of the connect form and then the logged-in functionality of the program. I can test that it loads the modal connect form correctly; enters the details and clicks OK (all fine so-far) but it does not appear to logically progress the program. The modal form just closes again seemingly without running the connect code from the program back-end and I'm back at the main menu not logged in to anything.
I have a feeling that I've either missed something really obvious or that it's simply not doable in NUnit.I have trawled the internet in search of anything similar but the closest was another SO thread that was really generic. Without being able to actually test the logged-in version of the program, I'm at a major hurdle.Another issue is handling message boxes that don't have unique identifiers (e.g. "are you sure you want to exit?"); these also seem to be a major pain in the arse with NUnit (If it makes any difference, I'm running the tests as a stand-alone project using a reference to the executable file of the built project, not the actual source)
I am deploying a VB.net 2010 winforms application, and when I install it on the client's machine, the install process also installs an instance of SQL Server 2005 Express. The application connects to a central SQL database on the server. To install, I am using the "Publish" option in VS 2010. Why does it do that? There should be no need for a local instance of SQL Express. Is there a way to avoid installing SQL 2005 Express (I know it is free, but I would rather not have it installed if possible).
