Control Array - Add New Event - Click Event Code And Calling It A Doubleclick Event

Jul 31, 2010

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

Heres the tutorial with my new code encased in asterisks ...

Code:

Imports System
Imports System.Windows.Forms

Public Class form1

Calling Button.click Event?

Jun 3, 2011

Im trying to create a webform that is a representation of a paper questionnaire that has 14 questions with yes/no answers. If an answer is no, then you must provide information as to why in 3 separate textboxes and store the information only when a user clicks no.I also have 4 drop down lists that are chosen before the user answers the first question that also need to be stored with the textboxes, but the ddl's value does not change after the user starts. Right now I have 3 textboxes and a submit button for each of the 14 questions that are hidden until a user hits a "no" button, in which I change the visible property of all of them and the user then types in their reasons and submits the answer. I am currently doing this for each question and i hide/disable the textboxes and button after submitted.

My problem is that for each event on the 14 submit button's is that I'm forced to open & close an sql connection and insert the values. I know there has to be a way to simply this some so that I dont have 14 different groups of the same code. I would also like a way to eliminate having 40 textboxes on a page lol, because the idea was to have a pop up box or something open that would let the user submit it and then return to the question instead of hiding textboxes, but the user has to see all 14 questions at page load so if you got an answer to that one then that might solve my original question.

Event Calling Mismatch In MaskedTextBox?

Jul 22, 2010

I have built a customized control inheriting the maskedtextbox in VB.NET. But i face some issues in the calling of events. For eg. if there is control named : Control1 and in the designer file i set the text property of the same to some value (Control1.Text = "test"), then the text change property is called. But i need to call the event only when the text property is changed during the run time (not while initializing in the designer file). Is there anyway to trigger the text change event only when the text property
is changed in files other than the designer one.

Calling A DropDownLIst's Selectedindexchange Event On Pageload?

Mar 4, 2009

I have an ASP.NET 2.0 that contains a dropdown list used to filter records based on a group number. For example, if the dropdown list selectedvalue = 3, only records containing a 3 in the group number column of the table will display. This is working perfectly. However, when the page first displays the default value is 1, and the records from group 1 do NOT display unless I trigger the dropdown list event. I am trying to get the records to display for group 1 when the page first opens to avoid having to use the dropdown when the page loads. The "drop down list control" filters records in a "data list" control.

I am thinking of writing a piece of VB.NET code to automatically call the Drop Down List's SelectIndexChanged event on the page so the user does not have to do it. how do I call that event from the "On Page Load" or, is there a better way to do this?

Calling Button Click Event On Load?

Jun 1, 2011

While studying sample code for vb.net, I put the code in a button click event and need to click the button to see the results. It would be nice to have this code run by adding Button1_Click() to save time but I get an error because of the parameters needed for the Click event.

I get a suggested "Generate Method Stub for Button click event" which is probably a clue to the problem if I had any idea what that means.

Calling Function To Update Value On Trigger Of Event

Nov 8, 2010

I think I have a timing issue. On the trigger of an event I call a function to update a value:

Private Sub t0_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles t0.Click
Input.ppProperty = "blank"
UpdateRecord("Hey", Input.ppProperty)
MsgBox(Input.ppProperty)
End Sub
[Code] .....

Notice the difference, the property does not update until the function is completely finished.
Why?

Forms :: Calling Other Project From Onclick Event

Dec 7, 2011

I have a question regarding VB.Net and Object-oriented programming.

I have a solution consisting of two projects.

One project is dedicated to the logic of the application, and one is only to show the Winforms form, and to reflect changes made in the logics project. In other words, when an array filled with various attributes residing in the logics project gets changed, then these changes should be reflected on the form (not that strange in theory).

Here comes the - for me - really tricky part:

I have created user controls, and these are residing in the forms project and placed on the aplication's form. When I click on any one of them, their respective onclick sub gets called okey, but how can I send a message to the logics project from their onclick subs? Basically, I'm not sure on what should be private or not, or possibly how to call the other project correctly. In any case, I can't get it to work.

To sum up: What I need is a line of code calling a class in another project, and someone telling me what should be private, static etc.

Interface And Graphics :: Calling The Paint Event?

Mar 22, 2012

This is a working example which draws a rectangle on different location every timer_tick and I fully understand now how it's working:

Code:
Dim i, timercount As Integer
Private Sub PictureBox1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles PictureBox1.Paint

[code]....

Now I'm looking for a way to draw this rectangles without refreshing them every single tick. I've just started using Visual Basic and I really don't know how to call/raise PictureBox1_Paint event every timer_tick or how to store drawing data in member variables?

Asp.net Vb User Control Raising An Event On The Calling Page

Apr 7, 2010

i'm trying to learn about user controls. I created a user control that has a textbox and a button. What i'd like to be able to do is when i click the button in the user control, populate a label in the aspx page. I understand that i could just have a button on the page that uses some properties on the user control to get that information.. but i'd like to know how to do it with the button the user control.. the reason for this is the button is just an example.. a learning tool. if i can get this working, i'd likely be putting thing in the user control that might require this kind of passing information. Anyway.. i've found some c# examples that i tried to get working as vb.. but once started getting into the delegates and events..

VS 2005 Calling A COM DLL In .net?

Jan 25, 2010

I'm having trouble getting a COM based DLL working in my vb.net program. The DLL is a C++ based COM DLL. When trying to use the DLL in my code, I get the ever so popular "Unable to find an entry point named 'Getdata' in DLL".

[Code]...

Both ways give me the same error. I've added the references to visual studio, and i'm able to bring up the DLL interface in Object Browser within Visual Studio, but for some reason i'm still not able to call it.

I think what I'm missing is small, but i'm new to calling COM DLL's from visual basic. So what am I missing? I've searched google until my fingers started to bleed and i've searched this forum up and down, but haven't been able to find anything.

VS 2005 Unattended Job Scheduling Calling .dll?

Sep 28, 2011

I have 5 separate class libraries where each one of thses are consuming separate web services (the web services connects to a server, runs stored procedures and return data tables to the .dll).

My task is to sequentually run these 5 jobs unattended through a job scheduler. I am not really sure how to do this and what my options are.I was planning on creating a driver (a console application) that would call each .dll. If this is a acceptable way then I am not sure how to reference and call each .dll, could I use import, add a reference to the .dlls and instantiate a new class, make a setup project with dependancies etc.
