I have two dropdownlists, the first is State & the second is City. I have the State ddl populated, but I would like to populate the City ddl via the selection in the State ddl. I am using autoPostBack, so it goes through the motion of updating but nothing loads. I am sure it is in the code behind or in the databind.

I am parsing a file which contains customer address in the following 2 formats:
Format #1 12345 Melrose Place New York NY USA 12987
[Code]...
I need to put the data into Address, City, State and Zip fields. I am able to parse and put the data (specifically line 2) in the fields for format #1 but am having issues doing the same for format # 2 because format # 2 doesn't have USA as a reference point.
[Code]...
how can i split this? i have two different formats:
2920 Emmaus Ave, Zion,IL 60099
200 Lakeside Ct,Apt 1426 St. Charles,IL 60174
i was going to split by comma but sometimes the apt will end up in the city name. i don't want that.
I have a database that has a text and a lot contain a free form of the person's address, city, state, and zip.
Incoming text would be:
John W Doe 1234 Big Lake Dr., Fort Worth, TX 76120 111-222-3333 jdoe@domain.net
Output of function should be:
1234 Big Lake Dr., Fort Worth, TX 76120
Here is some code I tried but doesn't seem to find anything:
Private Sub btnXMLTest_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnXMLTest.Click
lblOutput.Text = fnRegex("'John W Doe 1234 Big Lake Dr., Fort Worth, TX 76120 111-222-3333 jdoe@domain.net")

Firstly i'm not asking for the exact code here but the below is what i'm trying to do:I have a gridview with DropDownList and CheckBox and I have a button outside the gridview that will add a new row within the gridview.I have no problems with the adding row but I have a problem with saving the state of the checkbox/drop down list.Everytime I checked the checkbox and add a new row, all the DDL/CB will be reset.So how can I do it so that when I add a new row, the checkbox that I've checked before will still remain check.

I have 2 dynamically created ddls in which the second ddl populates based on the first ddl and the values of both come from a database. These ddls are inserted into a table that is dynamically generated based on some event. My problem is that everytime I select a value in the first ddl, the page load event is called and I lose the table. Is there a way to NOT call the page load on a selection? Or is there a way to generate the table with the values of ddls as soon as the page loads. I tried to fix this problem

View 3 RepliesI have a bit of a tricky scenario. It consists of some partial problems for which I have individually found solutions, but I couldn't find anything that makes it all work together smoothly.
-Upon selecting an item in a datagrid, a new page loads with the details regarding that entity.
-The entity represents a product that can have any amount of variants (such as a t-shirt's color or size)
-I dynamically add dropdownlists to this detail-page that represent these variants (there can be any amount of variants, and each variant can have any amount of different values, each value or combination or values from different variants representing a unique product entity)
-Upon selecting a different variant in a dropdown, a delegate is called that will change the session variable to the productId associated with the selected variant and a postback is fired that will reload the page with new data based on this productId
The problem: the postback is fired BEFORE the dropdownlist's (OnSelectedIndexChanged) delegate is called. Since this delegate defines the productId in the session, the new to-be-used productId isn't known at the time of postback.
Result: loading the correct data in the page is always delayed by one postback. Each time I change the selected index of any of the dropdowns, the page is loaded with data based on the session variable that the PREVIOUS OnSelectedIndexChanged delegate of the dropdown set.
I have a LoadData() method that sets the values of all textboxes, fields, labels etc. based on the productId stored in the current session. This method is called on Page_Load.
Private Property CurrentProduct As Product
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
LoadData()
[Code] .....
It seems that I haven't been completely clear on what does and doesn't apply to this scenario regarding Page Lifecycle.
1) My dropdownlists are added dynamically, which works fine on the first page_load.
2) The content of the dropdownlists is defined by what entity's details i'm loading on the page.
3) What entity's details I'm loading on the page is at first(not-postback) defined by the product I selected in a gridview in the previous page.
4) At postback, this entity is based on a sessionvariable containing the id of the entity.
5) This session variable is defined by what item in the dropdownlist I select.
6) This dropdownlist dissapears after postback since it's not defined on the page, but dynamically. So is the event.
So my guess would go towards some clientside script that stored the selected value before postback, but then I would be clueless on how to get that variable to the server since the logic that retrieves the entity is in the business logic layer which is far away from this page..
I have a window having 2 dropdowmlists(schemename-SN and propertyno-PN) , one chkbox ,one "VIEW" button.SN has options "all" with value=0 and many other options with respctive values.Now,i want the code should behaves as follows:

I'm trying to display the population of a city, as soon as it has been chosen in the combobox.I put it on my formload, and it will always read the index of -1 since it hasnt had a chance to be chosen, how would I bypass this without a button being clicked?

lblCurrentPop.Text = "The current population is: " & CStr(intPopulation(9))
Else
MessageBox.Show("You must select a city!")

I have found a couple of examples on the internet to do this but really struggling to get it working in VB. (Tried a converter but had mixed results) I need the selection options of a Dropdownlist to be populated based upon the differing values in the first dropdown list.
Can anyone help with a releativley simple example in VB? Not fussed if the values are "hard coded" in the script. Or a SQL bit that pulls the data from a table
I have following codes
str2 = "select sno,name from employees where sno =" & Val(Me.TextBox1.Text)
cmd2 = New SqlClient.SqlCommand(str2, con)

So I've gotten a lot of help from this forum for this incredibly large, incredibly pointless application I'm making right now.I need to be able to have people type in, say, the name of a city. Then it will display a table of Name / phone number.So I need a table that can change for each "city name", and can scroll down. I know I'll most likely have to save it to two variables for each "city", I'm already set up to do that. ( Variable Name, Variable Phone Number) What I don't know is how to... print the data into a table, or make two text boxes that will scroll simultaneously.If there is a way to attach a scroll-bar to two text boxes, that would be my preferred method. If I have to use a table, what would the substring and code look like to change:[code]

I am developing an application for an emergency services organisation using VB 2008 that will enable users to select a map zone of a city centre and plot icons onto it, then save/export the layered map with icons as an image.My problem at the moment is that I am struggling developing the point where the user imports in the icon (for example, a flame icon where a fire started) and drags it around the map within the picture box to the required area.I want them to be able to select their desired icon from a series of commandbuttons and for the icon to 'appear' on the picturebox and be enabled to be dragged around and dropped as required. The organisation already has such a thing working in Microsoft Word (!) and that uses the ActiveDocument.Shape.LoadImage function on a pushbutton to import the icon and then it is placed on the map as required, but this is really unreliable for them.I dont even know if you can layer images onto an existin picturebox within an application in this way and then export as a flat image.

We have to get the data from a Ship to a Data centre which is located in a city. And the Ship has broad band connection via Satellite . So for capturing data from the ship we suggested to create a WCF services which will be deployed in Ship. And the Application Running on the Data center will call the service and get the data and upload it to the data centre . The same type of Application will be deployed in the data center to upload the data to the ship.
View 3 RepliesI need to represent the following query using LINQ:
DECLARE @PurchasedInventoryItemID Int = 2
DECLARE @PurchasedInventorySectionID Int = 0
DECLARE @PurchasedInventoryItem_PurchasingCategoryID Int = 3
DECLARE @PurchasedInventorySection_PurchasingCategoryID Int = 0
[code]....
Now, I know that a query in .NET doesnt look like this, this is my test in the SQL Design Studio. Naturally VB.NET variables will be used in place of the SQL local variables.My problem is this: All of the conditions after "WHERE" are optional. In that a query might be made that uses one, some, all, or none of the conditions. V.PropertyID and V.Value can also appear any number of times.In VB.NET I can make this query easy enough by simply concatenating strings, and using a loop to append the "V.PropertyID/V.Value" conditions.I can also make a Stored Procedure in MS SQL, which is easy enough.However, I want to accomplish this using LINQ.
Ive managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
