Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

Apr 1, 2010

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Here's my call:

<script type="text/javascript">

function HelloWorld()
{

var yourName = $get('txtYourName').value;

Call A Delegate From Separate Thread?

Jun 10, 2011

So, I'm having troubles implementing a separate thread. This is because I have a simple class, and in it I start a new thread. So, as it is not any form, I haven't found any way to make it call the function in the UI Thread.

So, I cannot use the Invoke method. Is there any way to call a function from another thread?

Keep Each Module Separate And Call EXE's Or Should Create One Large Project?

Dec 15, 2009

The company I work for has a VB6 project that is using an ACCESS database.The project consists of seperate modules such as Accounts Payable, Payroll, General Ledger, and Inventory.At the current time each module is a seperate project in VB6 and the EXE files are called when needed.In total there are about 1300 forms in the project.We are moving from ACCESS to Sql Server and from VB6 to VB2008.The question that I (we) have is as follows; Should we continue to keep each module seperate and call the EXE's or should we create one large project?What are the pros and cons for each way?Is there something written that explains the advantages of either?

Call/run Excel Macro Within A Separate Visual Studio Application?

Dec 14, 2010

I'm looking to call an excel macro (excel version 07) within a separate visual studio application (visual studio express 2010). Basically, a user clicks a browse dialog button to select a xls or xlsm file which is then added to a listbox. Next, I would like the macro to run when another button is clicked. The macro looks at the first column in excel and moves the listed .tif images from one folder to another. I referenced the excel libraries, but seem to be getting hung up on a few code statements (''''ERROR see code below). I would like to run the macro within visual studio for any selected excel file or add the macro somehow to the selected excel file and run it.

'Here is the button click procedure

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
filenames = lstFiles.SelectedItem

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished

Jan 25, 2010

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).

Anyway what I am trying to do in steps:

1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.

The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.

I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?

Sep 14, 2010

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()

takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:

Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)

Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

Call A Function / String That It Uses Will Be Given To Function To Initiate A Download?

Some programs implement command parameters, Like my favourite computer game - Crysis - has them and windows media player has them.But how could i implement them in VB.NET..I want to have a component of my program built as a seperate exe - so it can be an Optional component.But of course the seperate exe, on load, needs data passing to it.So i need something like Process.start("Componentname.exe", "/StartDL <Suchandsuchastring>)/StartDL will need to call a function, and the string that it uses will be given to the function to initiate a download?

Override A Function And Call A Function With The Same Name From The Grandparent Superclass?

Sep 6, 2010

I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.

In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.

Running Function In A Separate Thread

Mar 31, 2011

when trying to run a function in a separate thread, my reason for trying this is because since the application is only run on one thread, the GUI hangs when the function is called.[code]In this code, the Print screen Button is pressed and the function HookCallBack is called.The problem is that the function has variables that need to be passed and returned, and while searching, i found a website that had an answer for this, and it required the function to be put in a class, and then it could be run on a separate thread while still passing all the variables needed.url...But the code cannot be placed in a class without giving errors and it seems to me like i did something wrong. The code is meant to be used in a form and not a class.My question is, how would i go about running the HookCallBack Function in a Separate thread?

Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field

May 18, 2012

Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer

[CODE]...

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.

-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.

VS 2008 Use The Value Of One Variable To Call Another Variable Of The Same Name?

Feb 7, 2011

I am trying to use the value of one variable to call another variable of the same name.I have 2 variable one called VAR1 and VAR2.

The variable VAR1 has a value of "VAR2"
The variable VAR2 has a value of "HELP"

I want to be able to get the value VAR2 from the variable VAR1 I have defined the value of VAR2 early in the code and now I want to call that value by using the value of VAR1.The reason I am doing it this way as I have a list of 50 variables that are pulled from one system. Each of these variables have the same name as the columns of a spreadsheet. The total number of Variable stay the same but the total column headers may vary each time. I need to loop through each of the column headers match them with the variable names and add the data to the spreadsheet.

VAR1 = "VAR2"
VAR2 = "HELP"
i =1

[code]....

This is the tricky bit...if the value of the cell(1,i) = "VAR2" How do I get it to display the value of the variable of the same name In this case how will I get it to display "HELP" when I only have from the VAR1 value "VAR2" I know my code will bring back the value as a string but I want it to bring back that string as a variable and display the value of that variable?

Setting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters

Feb 17, 2011

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.

For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

VS 2008 Call .exe From VBA Using A Variable

Apr 7, 2010

I have created a project using VB.Net(VS2008) and created the exe file. I have another project in VBA (Excel 2003). The project basically IC-Testing based. So according to the device type the Excel workbook name varies. For example I have AAAA.xls, BBBB.xls, CCCC.xls. When I open AAAA.xls, I want to call the .exe (which is developed in VB.Net) with the variable "AAAA". i.e when the exe program runs, it knows which Excel is opened or from which Excel the .exe is called. now I am using Shell retval=Shell("d:Monitor.exe",1). Using this the exe is called and running fine. But the Monitor.exe doesn't know which Excel called it, whether it is AAAA.xls, BBBB.xls or CCCC.xls.
