Calling Methods From The Tabpage In VB
Jun 26, 2009
I have a tab control on first page of which there is a flexgrid. some functions are called which throughout make chages to this flexgrid. now during runtime I create more tabpages with exactly the same Flexgrid (as in I have named it the same as the first one so that I should be able to call the same functions and the same modifications should happen with this flexgrid as well. How should I call the function so that the flexgrid used is the one on my new tabpage. if I just call the function with the code Call functionname(), it modifies the same flexgrid control in the first tabpage and does nothing to the new ones on the newly created tabpages

I've been wasting so much time on this. Basically I want to have a list of objects and I want to call some specific methods of some specific bjects..g.MsgBox(Instances(0).Position(0).ToString)It should alert a number that presents the X position, but it is not working... the box does not even appear and no errors.

It's been a while since I've had the time to browse through here, answer questions and ask some of my own. Just got a job at a custom business software developing company! But I do have a question I'd like some clearing up on.
What I have here is 2 classes, one inherits the other. Both function similar so a lot of the methods are the same for each. The one in particular is Reset_Class()
Here is a sample code of what I'm trying to do.. My question is, is it correct?
vbnet
Public Class Form1
Private Sub Button1_Click( ByVal sender As System.Object, ByVal e As

In C# I'm calling a function on an interop class (Connection, written in VB6), which itself returns a plain object (System). Then there's a function on that object (InitialiseData) that I also call (even though the compiler isn't aware of it). var isInitialised = Connection.System.InitialiseData(path); The problem is, because that System object is returning a mere Object, I get the compile error "cannot resolve symbol". I can see why, but the same thing works fine in VB.NET:

I have a form (frmMain) that contains a custom control (con class). frmMain contains a combo box control and when the user selects a value from it, I pass this value to a sub routine within con class (see red line below). This purpose of the sub routine is to populate a set of comboxes contained in con class according to the value that is passed in.
Private Sub cboGuidelines_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboGuidelines.SelectedIndexChanged
If bChanged = True Then

I have the following class in a .NET class library:
Code:
Public Class JasonTest
Sub New()
End Sub
[Code]....
The .AddNumbers call works fine, but the AddStrings call yields the error 'Object doesn't support this property or method'.
Is there any way to call a shared method from .NET in VB6? I was unable to find any documentation on this.

I want to use reflection to dynamically call a dll (not an assembly, non-managed, possibly COM object model) in vb.net.I've seen several different methods of calling a method in a dll that is a .net assembly - but I have not found the way to dynamically call a method inside of a dll like user32.dll or winmm.dll. I believe this would be called late-binding?
The reason I'm asking is because I am building a language that will depend on external libraries for lots of different functionality. An example (in this language I'm building):
Declare Function mciSendStringA using "winmm.dll" (strCommand As String, strReturn As String, returnLength As Integer, blah As Integer) As Integer
Declare Function WriteConsoleA using "kernel32.dll" (hConsoleOutput As Integer, lpBuffer As String, numberofcharstowrite as Integer, lpReserved as Integer) As Boolean
When I build the interpreter for the call to mciSendString in winmm.dll, how can I use reflection to handle this? I want the user to be able to reference any dll/method they wish.Can I get some guidance in the right direction? Perhaps even some vb.net code that I can take apart and understand?

control which will need to be reused in several forms in my program. It basically consists of several buttons in a panel. To start with, what I need to do is get the button values from the control into a text box on the first form. But I don't want to have a method calling the textbox directly from within the control, because then it won't be reusable in my other forms. Is there something I can do in VB like parentform.textbox.append for example, where you can generically call the methods of the form in which the control appears?

I am using System.Windows.Forms.TabPage to store an entire TabPage for later use in My.Settings. Here is a brief description of the application.
I have a TabControl that has 3 tabs. One for user input, another tab for equipment settings, and then a final tab for Oven settings. On the user input tab, if the user de-selects the checkbox for Oven, the oven tab is saved to My.Settings and hidden.
I can then run the application without oven control. After running, lets say the user would like to re-run, this time with the oven. They go back to the input tab and re-select the Oven checkbox. However, the Oven tab doesn't re-appear. When stepping through the code, the is nothing stored in My.Settings for the oven tab page. Why not?
Also, I can open the application, and check, then uncheck the oven checkbox and the tab is hidden, then returns. I can do this all day. However, after running the tab will not return.

winforms .net 3.5 Ultrawingrid 9.2 In my subclass of Ultrawingrid.Ultragrid :
[Code]...
This works fine. But when the grid is dropped on a TabControl tabpage, the ctrl-tab looks very different to the sub above. e.keycode is seen as controlkey {17} I realize that by default cntrl-Tab moves between tabpages. I need to override this behavior. My thought is I probably need a subclass of the tabControl which will pass the keycombo through just as the form does but I confess to being clueless as to how to accomplish that. I tried to override the onkeydown of a tabcontrol subclass and just issuing a return and not and base call to onkeydown if the ctrl-tab combo was pressed but it seemed to see the e.keycode as controlkey as well.

I am not sure how clear my question is by the title, but I am trying to make Class methods instead of Instance methods in Visual Basic that way I don't have to waste memory and code creating temporary objects to execute methods that don't need instance variables.
I am not sure if you can do that in VB but I know you can in Objective-C by using either a "+" or "-" sign in front of the method declaration. And in C++ (at least I think, I can't remember) you put the static keyword or const keyword in front of the function.How would I do this in VB if it is possible? Or should I just make a separate set of functions that are not members of a class?

Is It possible to have a "new tab" button on a tabpage, like in IE how theres the little square you click to add a new tab. So normally I use a separate button (like on a toolstrip) to create a new tab, but I want to have a button that floats next to the last tabpage in a tabcontrol that adds tabs. It would be great to have a little button at the end of each tab that you can click to close the tab, like in google chrome (I have an attachment, something as close as possible to that. like this is a normal "tabpage button"(the button where you click to show whatever is in the tab) [Tab Text.... ] and I want something like [Tab Text.... X] where the X is a button that closes the tab.

I'm trying to add a tabPage to an existing TabControl named TabControl4 I went all over it with the Debugger and everything is fine, but it won't show the TabPage in the TabControl. That's the code, Notice all the information being added to the TabPage is retrieved from a database so don't pay any attention to it, plus the software is in Hebrew so just ignore the Hebrew Strings.
