I'm wondering if is it possible that the events for a certain object will be executed by another events under a different object?For example.I have a button named Button1, and I have a ListView named lstView. What I want is that when I click on Button1, the events that will be executed will be the one under lstView.
Here are my codes:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
lstView_KeyPress(Button1, e) 'This is the part where I don't know what to do.
End Sub
I have been trying to implement the jQuery weekcalendar using .net. What I can't seem to figure out is why weekcalendar states events.events is undefined after I make an ajax call to a webmethod I created which returns JSON. Below is the relevant code:
I created a control that has picture box control docked within it. This control allows me to "animate" the image by swapping them out by setting the interval to swap them at. I want to use this control kind of like an animated icon within a application, but because the picture box is docked, the control I created won't respond to the events, MouseHover specifically. [Code]
I don't know how to use these events and get the appropriate values out of these events ....here is some code that I have copied from a website...
[code] Private Function MouseHookProc(ByVal nCode As Integer, ByVal wParam As Integer, ByRef lParam As MSLLHOOKSTRUCT) As Integer Try If nCode >= 0 Then Select Case wParam
is there a difference between shared events and non-shared events?
Private Shared Event EVENT_something_changed() Private Sub SUB_handles_something_changed() Handles Me.EVENT_something_changed End Sub
no errors with this code, but how is Me possible since the Event is shared. it seems like there's no errors between switching shared with un-shared and switching Me with Myclass, all 4 combinations seem to work, isn't that weird
I'd like to be able to access the events in a C# DLL so I can display a Progress Bar as the file analysis is carried out - the DLL is written by a third party using VB.Net.
Details C# FileAnaysis.DLL Contains a public class FileManager which contains 2 public subs public void ProgAnalysis(string fileName) public void ProgAnalysis(string fileName, ProgressChangedEventHandler progressChangedEventHandler, RunWorkerCompletedEventHandler runWorkerCompletedEventHandler)
How do I access the events generated by second sub in Vb.Net?
In VB.NET, can we pass an original object as an argument without instantiating it? For example, I have two forms in my project formA and formB. Now I have this code.
[Code]...
Apart from this, in VB.NET in any class like formA, if I type formA, I can see all the objects and controls present there but not in C#. Again, I have to make a new instance to see all the controls. This becomes a problem if I want to manipulate two running and working instances with each other. So what basic thing am I missing here?(I am an amateur programmer migrating from VB.NET to C#. Things are going nice and clean expect for the ones I've recently figured out.)
I am trying to pass a 2D array into a dll I wrote in C. When I run the program, it crashes at the first line (in the dll) that I try to read the array. It gives an error that it is trying to read protected memory. I'm guessing this means the array was not correctly passed to the dll, so the program is trying to read a memory location that doesn't exist. Is the problem somewhere in my VB code? If not, it must be in my C code, right?
Here is my VB code:
Declaration of the function in the dll:
Code:
Private Declare Function image_processing Lib "image_processingDLL.dll" _ (ByRef image_array As Long, ByVal dpi As Long, _ ByVal xDim As Long, ByVal yDim As Long) As result Calling the function:
I have a pdf on one server I need to pass on another server. Both have WCF's published to them.On the 'serving' server, I have the following code (thanks antisanity!):[code]But I have no idea how to actually write the file on my 'receiving' server. I've been playing with System.IO,[code]
I am calling a crystal xi report from a windows form and passing 2 date parameters and a customer name. In some cases this customer name contains '&' eg Brown & Williams
In these cases my report fails and errors. if the name doesn't contain '&' it works. How can I pass the parameter with a & in it ?
I'm writing a program to control another program using redirected input and output. This is a simple sample of what i want to do that works. But since I'll then be adding other commands and waiting for other responses like username: then password: then. I'd like to put the "wait for" and "send" sections in sub routines. My problem is somehow I'd have to pass a reference to the process or at least sIn, sOut and sLog to those routines and I don't know how. Do I dim the process as global or???

I am using Visual Basic .NET 2005 and I need to call a DLL made in VB6. Couple of days ago i wrote a test dll in VB6 and called it from VB.NET. I passed an array and another variable. And the dll got it and displayed the values in the array. (I didnt save that code)Now when I am writing it again I am getting an error "Specified array was not of the expected type." [code]If I do not pass array then it accepts but otherwise it does not. The array here is CD().
I`m trying to code something to populate an outlook message with data from another application but i'm having problems passing the data into something which could be executed.I'm basically using the script Sub SendMailOutlook(ByVal Recipient , ByVal Subject, ByVal TextBody , ByVal From )
Dim olApp As Outlook.Application olApp = CreateObject("Outlook.Application") Dim olMail As Outlook.MailItem
I am using a function that is provided by the maker of an IO device that I'm using and the call for this device turns on and off the 16 ports on the IO device by sending the value true or false to the board. The call is as follows:
I have my own little tutorial about passing variables, and if you'll look at the code below, you'll see how I am passing the variable from one sub to the secondsub. Here's my question, how can I pass a value back from the 2nd sub to the 1st? So if I want to sum intA plus intB, and want to return that value to the first sub, how do I do that? [code]
I find that I write a lot of code within my classes to keep properties in sync with each other. I've read about Events in Classes, but have not been able to wrap my head around how to make them work for what I'm looking for.For example, in this one I always want to keep myColor up to date with any change whatsoever in any or all of the Red, Green or Blue properties.
Class myColors Private Property Red As Byte Private Property Green As Byte
[code]....
If one or more of those changes, I want myColor to be updated. Easy enough as above, but is there a way to work with events that would automatically do this so I don't have to put myColor = Color.FromArgb(Red, Green, Blue) in every sub routine?
Is it possible to get an asp.net code (preferably vb.net) to query a sql server for results, but for it to somehow wait for a response from the server when a change is found in the records without resorting to server intensive loops?For example, I want to write a query which checks the date of a record, if the date is different from last known date, only then should the query return the results.
