At the moment I am trying to generate buttons, where the mouse position is.I have a timer which gets the mouse position as 2 string variables:[code]what I want to know is how do I access each separate button, I mean if I went nodebtn.hide() then all of the buttons will disappear. However I would like to select a button to chose from the present.

I have an ASP.NET form with a cancel button that is supposed to, after confirmation from the user, redirect them to another page. I'm using javascript for this. It works fine in a simple HTML page, but apparently something is interfering with it on the .aspx page. The popup message works perfectly, but clicking "Okay" does not take you to another page. I have tested the if statement and it is working correctly, the only thing it won't do is leave the current page. [code]...

I am trying to automate an application and I need to respond to a prompt that is being issued by the application that I've started. The application is issueing a message and I'm using some api controls to respond so that it doesn't stop but they are ignored. here's the code I'm using and I'm hoping someone will look at it and tell me what's wrong. The odd thing is it works on my laptop (Windows 7 Pro 64 bit) but fails on my desktop maching (same OS).

I did a super simple calculator with ASP.net with five buttons: add, subtract, multiply, divide, clear. There are five separate functions for each button's click event. For example: Sub addfunction(ByVal s As Object, ByVal e As EventArgs)If Not IsNumeric(input1.Text) Or Not IsNumeric(input2.Text) Then resultLabel.Text = "You entered an invalid or missing number"
[Code]...
How might I be able to combine all 5 of these functions into one? So for example, all the onclicks will refer to the same function, but will somehow be able to determine which button was clicked? I forget a lot of VB.net from a year.
This is in regards to the toolstrip spiltbutton control.

In an application with multitab on a user Form after collecting some information I will plug it into an access database and collect data and disply it with another "Second" User form.On the second user form I make a selection from 1-10 selection on the second user form, and again I will read the access database using the selected data by the user and would like to plug in to the First user form and close second user form.Somehow my textfield is not accessible and I get the yellow tip of "PLName is not member of 'Windows.System.Forms.Form'"[code]
View 4 RepliesI'm using Visual Basic Express 2010. I have the prompt, the textbox and the calculate button. For the answer do I have to make a separate label for the answer in seconds and the actual response "That will take (separate label for answer) seconds" I made a click event button and assigned the following as global variables at the start of the form:
Const intSpeed As Integer = 1207
Const intTime As Integer = 3600
Then I made a click event for the button. I don't know what the formula is. Basically the user inputs a distance in the box, the calculate button tells you how long it will take for the vehicle to travel that distance in seconds.
Here's the interface: [URL]
Criteria:
Are We There Yet?
The Thrust SSC, a super fast vehicle tracked at 1207 Km per hour (750 mph) was clocked on the Black Rock desert back in 1977. Build an application that will tell people how many seconds it would take to get to their destination if they were driving the vehicle. Of course this doesn't include having to stop for stop signs, travel through school zones, or slow down for corners.
You need to include the following:
1.) Design the application with a prompt label and textbox to collect the distance from the user.
2.) A calculate time button
3.) The form must have the text property changed to read "Are we there yet?"
4.) The objects must have both the Text property and Name property changed to an appropriate value.
5.) A constant global variable should be used to represent speed of the vehicle.
6.) A constant global variable should be used for seconds (there are 3600 seconds in an hour)
8.) A local Dim variable declaration can be used within the button click to hold the distance value.
7.) Variables should be declared with the most appropriate data types.
8.) Include a "Text Changed" event to reset the time in seconds to a blank value when the user starts entering in a new distance.
9.) Comment code should be included

I have produced some VBA in Access that creates a spreadsheet.I have also created an SQL query that retrieves records from an Access table.I have 48 tables (each table for a specific institution centre).I have created another bit of VBA code that creates a spreadsheet and loads the records from the query in to the spreadsheet.Each centre has a unique Sequence Number (Indent Number)At the moment though, all I can do is import one table (records for one institution) in to a spreadsheet. I want to end up with calling the function and having an output of 48 spreadsheets being saved to my desktop, each spreadsheet containing records of a different center.I have thought about putting a loop in, but not sure how I would quite go about it.
Here is my code to create the spreadsheet:

I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have

I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.

I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
