View 1 RepliesI have a aspx project, I'm using web developer 2005. I am currently trying to locate the exact location of my project.

Is there anyway to find out?
View 1 RepliesBasically I am looking for a means within a asp.net 2.0 (or higher) application, to identify a time zone and UTC offset for a specific location and date. I want to be able to look up the time zone rules using either city & state, Zip, or LAT & LON I have an event database that tracks location, date and time for the events. Times are recorder relative to the event and the records do not currenlty indicate the timezone for the event or whether or not DST is in effect. Recently, I have encountered a situation where I need to link several events across different time zones. What I am looking to do is:
first, record a master event, say for August 13 2012 at 8:PM in New York, NY 10021
Second I need to record a related event in Houston TX.
When I record the related event I want it to automatically populate the date and time relative to its local time time zone rules. To do this it needs to be able to identify the effective timezone and UTC offset for the master event as well as the linked event so that I can calculate the correct date and time to display on the satelite program. As a future update I would probably capture the time zone /utc offsets with each program so that I don't have to recalculate the master record each time I want to add a related event.
So far I have not seen a way from system.timezone or timezoneinfo to be able to look up a timezone and the effective UTC offset of a given date and location.

I researched this and found I had to use something called "ScreenToClient" [URL]...what I want to do is to have a picture box that I can just get the coords from easily (for example 0,0 bottom left hand corner)
So how do I get that to work? (im guessing something like comparing the picturebox size to the form size then working it out but im not quite sure how to do that.)

I have a combobox that drops up instead of down. I'm setting the selected item to the one on top of the list. I'd like to move my mouse pointer to point to it, so that the user that wants to click on that item doesn't have to move his mouse. I found how to move the pointer, it is with this command:
Windows.Forms.Cursor.Position = New System.Drawing.Point(x,y)
but I need to know how to get the location of the selected item in the combobox.
The code bellow should perform a mouse click at the location the cursor is pointed, however it only activates the control from that location.

Public Class Form1

I am new to VB.NET, Now i'm working with Events in VB.NET, I have two event methods, Mouse Click and Mouse Down for a single button in a form, I have displyed a message in each of these methods but only mouse down event is triggered. Why Mouse Click is not triggered? Similiarly I Did the same for Mouse Enter and Mouse Move for a particular button, in this case both the events are triggered.
View 2 Replieshow to raise the mouse leave and mouse hover events for VB when i place my mouse cursor over the button.
When my mouse cursor is over the buttons, it will raise the mouse hover event and open the form, then when the mouse leaves the button, it will close the form upon raising the mouse leave event.
but currently, When i excute this two events, the for will open and close very,very fast. so fast that it is like spamming the VB.
So i am wondering how to change the code that i have to excecute the event one time every time the mouse is over the button which is created at run time.
the codes to execute these two events are:
Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
For Each ctl As Control In PictureBox1.Controls
[Code].....
[URL] I have tried heslacher's method which is Hi clzanas, you problems had been the result of calling a for each loop inside the events. If you only want for the button you hoover / leave to call the ShowDetails.Open/close, then you can take the code below:
Private Sub Button_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs)
If TypeOf sender Is Button Then
ShowDetails.Close()
[code]....
But i got the same results as my previous code, resulting in the form opening and closing so fast that it is like spamming the window.
I have a database which need to be assigned into array arr()(), e.g.
arr(0)(0) = aa arr(1)(0) = ab arr(2)(0) = aa
arr(0)(1) = bb arr(1)(1) = ba arr(2)(1) = ba
arr(0)(2) = cc arr(1)(2) = cc arr(2)(2) = cc
I need to find distinct / unique value in each arr(k)(0), arr(k)(1), arr(k)(2); where k=0..2. Then i need to insert the result into array cat as follows:
cat(0)(0) = {aa} cat(0)(1) = {ab}
cat(1)(0) = {bb} cat(1)(1) = {ba}
cat(2)(0) = {cc}
I've tried code below but it doesn't work. The assigning process into array arr()() from DB is OK. Problem only come up if I try to find the distinct value (If Not (cat(j).Contains(ds.Tables(0).Rows(i).Item(j))) ... End If).
For i = 0 To 2
list(i) = New Integer(3) {}
For j = 0 To 2

I am trying to find a set of missing values between an array and cell values from a DataGridView. The array is a set of numbers from 1 to a user-entered maximum number. For example, if the user enters 10, then the array will have the values 1,2,3,4,5,6,7,8,9,10. The rows in the DataGridView might have values such as 2,4,6,8. I want to create a second array that would have the values 1,3,5,7,9,10. I believe I need to loop through the array values and compare them to the row values in the DataGridView. But I'm stuck on the method of either adding or removing values (or doing nothing) to the second array as the array value loops through the DataGridView. logic or some VB Code that will produce the results I'm looking for?

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.
