is there any way to extend upon a procedure itself?like i want to be able to do the following
Code:
public sub test()
msgbox(special())
end sub and it should popup a string, let's say "cool", plus i shld be able to use special() in every single sub but if we call special() from a function it should be rejected. how can that be done?
also, we should also be able to do the following
Code:
public sub test()
msgbox(specialvariable)
end sub whereby specialvariable is accessible by every sub.
I have a couple of bits of code I add to a textbox in my codebehind on form.If I wanted to extend this class or somehow create a shared instance of this code so I can pass in the parameters for text to display in textbox and use in any of my forms.. [code]
In order to organize various methods of my MainForm class, I would like to categorize them into several files. Of course, the methods would still need to access form elements and additional variables I added in the MainForm class.
Correct the problems with this function, and then extend it so that it also returns a usable array of pointers to some structures.
The extended version of this function should: Maintain the same "char *" return type which returns a pointer to a usable, for storing a C string, memory buffer.
In addition, also return a usable array of pointers to structures. This array of pointers is of variable and random length, which must be obtained using GetNumberOfSomeSeqsToGenerate(), which is called, ONLY, from within this new extended version of the function.
The type of these structures and the function that should be used to get these structures are defined as follows:
typedef struct { char* name; /* '\0'-terminated C string */ int number; } SomeSeq;
This has got to be one of the most frustrating issues with asp.net. I first got the error parser error cannot load default and as I have done before checked if the naming was correct in th bin folder and made the changes accordingly. Now I get the following error:
somethiing._DEfault is not allowed here because it does not extend class 'System.Web.UI.Page'
where something is the name of the project in the properties. I have the following code in Default:
Namespace FormDiscovery Partial Class _Default Inherits System.Web.UI.Page Shared settings As New System.Configuration.AppSettingsReader
[Code].....
Now I have deleted the project and other in the solution and created a new one and still this error and if I take the 'something' name away I get the cannot load default error.
I'm writing a .NET CF (VBNET 2008 3.5 SP1) application, which has one master form, and it dynamically loads specific UserControls based on menu click, in a sort of framework idea. There are certain methods and properties these controls all need to work within the app. Right now I am doing this as an Interface, but this is aggravating as all get up, because some of the methods are optional, and yet I MUST implement them by the nature of interfaces.
Since you are repeating same operation three times it is best to make a function for it.
CODE:
labels 1-6 are randomly generated numbers, text boxes 1-3 are the input boxes and the code above shows how if the answer in the textbox equals the labels added together, you win. This code works -
I have created labels 7-12 now, and textboxes 4-6. How can I extend this program so it has subtraction as well?
If this problem definition isn't detailed enough, let me know and I'll add more detail to this description.
How to extend existing components in Visual Studio 2005 to add my own features and functionality. For example, I want to extend datagridview control to include my own extra features.
I reference several 3rd party libraries in my application. I want to put all of these libraries in a folder that is different than where the executable file for my application is located. I would also like to put all of the libraries that are required by the 3rd party libraries (but not referenced by my application) in this same folder.
I need to be able to put the application (and the referenced libraries) on a thumb drive and run the application from any computer without any installation or registering of components. This condition is satisfied if I put all of the required libraries in the same folder as the executable.
For example, if my application is located at E:MyApp then I would like to store all of the 3rd party libraries in the folder E:MyAppDlls. Any way to store all (or at least some) of the libraries in a separate folder?
As topic says, I need to extend the features of a standard Silverlight ComboBox to also support Commanding. Since I follow MVVM I need my ComboBox to communicate the SelectionChanged event to my ViewModel.What would the code look like for doing this? I want to be able to put the Command attribute on my ComboBox XAML control.
I need to extend the functionality of the ToolTip control...Problem: I need to show some introductionary instructions to my users the first time they see a new form based feature in my app. Something along the lines of: '...Welcome to the blah, blah, blah feature. To do this, click that, mouse here, press that so on and so forth...'
Then I want a 'Don't show this again' check box somewhere near the bottom so the 'welcome screen' can be supressed. Currently I'm thinking of loading an app wide form (Public Dim frmMyToolTip as frmToolTip) and using it's .TopMost property to ensure that when I show it, it appears over my modal form (I can Hide/Show at will.) Also without a caption or border, my users can't move it.
As it will be displayed on top of a Modal form, I need a Background worker component to run a timer which will hide the form after a set period. I can store the state of the CheckBox to stop the form from showing next time if user does not require it.
The maximum value that works for AutoPopDelay property of ToolTip is 30 seconds (30000 milliseconds). Any values greater than this maximum will be defaulted to 5 seconds (5000 milliseconds).[url]...
How to set to extend the duration show time for ToolTip? or alway show until the mouse leave the control?
How to extend the session time. There are many form in my application like parent and child forms. So how can I make pop up to appear when session times out and the pop up should appear on the form where the user is currently in, when popup comes I have to disable all forms like(they should be transparent (i.e) user should NOT be able to edit them).
I have a Class, which I create an instance of in order to use, however I have a couple of functions (which don't really relate to the instance data) which I want to use when an instance hasn't been created.

Example of what I'm trying to do:
' Log a user into the system (this works) Dim hedwig As New CustomSecurity hedwig.Login("username", "password")
I realize that this is a very basic question, but it's been a long time since I've played with VB. Why can't I call the Synch() Sub/Function in my CMMS_SCAD_CLASS class from my Main module? I get the following compile-time error:
'Synch' is not a member of 'ConsoleApplication1.CMMS_SCADA_CLASS.'
Main class:
HTML Module Main Sub Main() Dim meterClass As New CMMS_SCADA_CLASS()

Dim hmod As IntPtr = GetModuleHandle(Nothing) 'Work Dim addrs As IntPtr = GetProcAddress(hmod , "TestFunction") 'Not work, always NULL why??
I want to create a function inside my class that will return a boolean on the existence of some data within any structures created with the class.
Public Class MyObject Public Object1 as String Public Object2 as String
[code]....
What I don't know how to do is refer to the object that called the function to get values, including the number of items in the referring objects array.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load If My.Settings.registered = True Then Form3.Show()
[code]....
This is my code for a trial application. The code is pretty basic but what i couldn't figure out was how i would be able to prevent users from changing the date to extend the trial ("error" i would be getting).
