I am creating an application with html using vb as the back end. Microsoft Visual Studio is the application I am using.I have two drop down boxes...one called department, the other program. When a department is selected, I want the program dropdown to only display the programs that are associated with the department chosen. I have found several different codes to do this but nothing has worked so far.
View 4 RepliesI am developing a program that makes it easier for users to log on to a website and search for specific data. I have the first portion finished in which I have a form with the Ax Web Browser control.
The web browser control navigates to a local website and automatically logs in for the end user. This is done by using code which automatically fills in the username and password and then submits the form to logon using something similar to this: WebBrowser1.Document.Forms.Item(, 0).elements("txtUsername").value = "user"
Once logged on - there is a search page which contains a combo box and list box. I am trying to set specific values for the combo box and list boxes.For example - the combo box on the website is titled: cbxDate and contains the following values: Today, Yesterday, This Week, This Month.
A list box titled: lstArea contains the following values: Zone A, Zone B, Zone C, All.I am trying to figure out if there is a way through code to select, in this example, "Yesterday" in the cbxDate and "Zone B" in the lstArea on the webpage.If anyone knows of a solution, please feel free to let me know. Be advised that I am using the Ax Web Browser Control.
I'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:
.cbbCOMPorts.SelectedItem(1) =
True
While this compiles, the computer does not like this at run-time. It throws an exception out:
"Object variable or With block variable not set."
I have about 4 different tables with the exact same column names. What I would like to do is select the top 4 records out of all of these tables combined ordered by date (as date is one of the columns that they all share).
View 1 RepliesAssuming this schema:
Table1 (Col1 int, Col2 str, Col3 str, ...)
Table2 (Col1 int, Col2 str, Col3 str, ...)
[Code]....
I need to select all records from Table2 where there are NO records in Table1 having matches of both Col2 & Col3. For instance, Table 2 records where Table1.Col2 <> Table2.Col2 AND Table1.Col3 <> Table2.Col3.
after selecting an item from a drop down list the focus can move to a button control with example code in .Net
View 1 RepliesI was wonder how, if you can, can I create a WebBrowser control or something similar to this, that will contain a selected area of information, and that information only. So it doesn't load and show the whole web page, only the part I choose.
For example, I would only want to show the weather portion of this webpage: [URL]
How can I get a specific area of a webpage, loaded into a form, that is able to be reloaded/refreshed later on?
Here's how I'm trying to manually select a specific item in my combobox. cbEditCategory.SelectedIndex = cdEditCategory.Items.IndexOf(editItemCategory) I setup a msgbox to show "cdEditCategory.Items.IndexOf(editItemCategory)" and it's reporting -1. Why is it not giving me the right index?
View 2 RepliesI have encountered a small issue with coding a portion of my Visual Basic program. In my program, I have a variable that contains text data. I would like to be able to select certain text in the variable and place it into a textbox.
For example, my variable is called strCallInfo.
strCallInfo contains the following value:
Address: 123 Law Rd
Location Info: Carbon Police Department
[Code].....
Note that the values in the textboxes are equal to values in the string variable. The only problem I am encountering is how to sort the string and place certain values into specific text boxes.
am designing a project in vb 2008 but i would like you to help me a code that adds items in a combobox with a drop down and also a code that clears all text boxes in a form if i click a refresh button.

I just started learning VB.NET about a moth ago (I have been taking classes, so its been about 5 days worth of classes) and I decided to work on this project idea I had. Essentially, it's a database to keep track of anime and manga that I, or whoever else uses it, have watched/read.[code]...
However, now I want to make it so that when one selects a specific title in the list box, it will show the data in the tags below the <series> tag that matches the item selected in a label. One thing I just thought of is than since the list box gets populated in the order that the series are in, it could be easier to go in order from first item equaling the first <series> and so on.
In VB.Net 2010, is there any way to do multi-select in a drop-down/combobox, preferably with check boxes in the drop down? I've seen various discussions on the 'net about this but no such beast appears to exist within the tool.?
View 4 RepliesI have a pop up form that contains a listbox. Right now I am telling it exactly which text boxes I want to be able to drag and drop to, but I was just told to have it drag and drop to every text box on the main form.The main form with the text boxes has a bunch of tabs on it that hold each section. Each section has text boxes, so how would I code it so they are all capable of allowing drag/drop without specifying each one separately?
This is the code from my pop up form:

I have two list boxes. A users selects a value from each, clicks a button and the application creates a relationship between the two selected items by saving them in an array and displaying the relationship in a third list box.
What I want to allow is for users to be able to drag a value from one list box and drop it on top of another value. I have the code to capture the value of the item dragged but I don't see how to capture the item that the data is dropped onto.
Is there a way to capture the targeted selected item?
I have a datasource linked to a table in a database.When I wnated to display this data on a form, I just dragged the datasource onto the form and it did everything for me, including the code to fill it;
Me.ProjectFileTableAdapter.Fill(Me.ProjectFileDataSet.ProjectFile)
My problem, is that this program will have multiple users, and I don't other users to be able to see each others data. So the problem with the above statement is that it fills the table with ALL the data in the datasource. How can I make it only display data that is for a specific user?Here's the code that is used to fill the tableadapter:

I have created a database with a couple of records to get started, also I have attemted to implement the database in my forms. I want to add, delete, edit and save new records into the database so when I use it or re open the program the entered data will still be there. Also, after I have implemented these things, I would like to be able to import data from the database into textfields or comboboxes. I have a basic email client and I would like to import these contacts into the datafields. However, I will be trying to achieve that later.I am trying not to use the data connection wizards as I am learning the code as I go along. I have been reading up on databases for about 2 days not and i'm still struggling.This is to add contacts with the fields.I have 7 labels with text boxes, using the naming convention lblFName or txtFName etc;
-First Name,
-Last Name,
-Nickname,
-Email,
-Phone number,
-Address and
-DOB
I have 4 buttons;
-Add record
-Delete record
-Save record
-Next record
-Previous record
I don't know whether to use datagridview, listboxes or something else to display the records.This is to give you an idea of what I have done so far.However, I cannot find a way; despite my best efforts over the last 5 days to link the database that is located in the same folder as my program.If anyone could point me in the right direction on how to code this into my program, or post some links of which I can read, learn and understand the code.

View 1 RepliesI am creating an application which will allow users to search parents names and display their childen respectively in a datagrid.I have created a form with two text boxes, a search button and a datagrid. The two text boxes are txtFName.text and txtLName.Text. On clicking btnSearch I want to be able to run a search to the SQL database for specific records.So far I have been sucessful in doing so with a listbox but I would prefer to have the data populating in a datagrid as it is more cleaner.

I'm using vb.net. Basically, I have a drop down list, text box and a submit button. You choose a movie director from a drop down list, then type in a movie, click button and it adds the data to my database.There's another button which hides/shows drop down list, text box and submit button using Visible = True and Visible = False, but what I don't like about it is when it hides the things I said before, it leaves some white/empty space like if they are still there, but not visible.Is there anyway to put some kind of holder/container and place a button which when clicked could add my drop down list, text box and submit buttons to that place?
View 1 RepliesI'm trying to drag an item between two Groups in the same ListView called 'listTasks'.

With listTasks.PointToClient(New Point(e.X, e.Y)) you could use listTasks.GetItemAt(p.X, p.Y) to get the ListView item you're over. Is there something like this for Groups? Or perhaps a better way to determine what group is the target of a drag-drop?

I want to make a program with vb 2008 and I face a problem, but firstly I will explain you what I have done already. I have a database(Microsoft access) named Receipts and there 2 tables Receipt and TaxPayer. At visual studio I've created one login form which I chose(from project properties) to be my startup form and another form Form1 that has a datagriedview which is connected to my database and gets data from the table Receipt. The validation of the user at the logIn form and tha connection with form1 works perfectly but here's my problem.When a user is valid I want to appear at the datagriedview of form1 only the records that have to do with him.I forget to mention that TaxPayer table has 3 columns,username,password and and a code(AFM). Instead all the records of Receipt appear. I know that the problem is at the Fill Method which looks like this:

I have a dataset called KeyData made up of two tables Customers and Orders.
I have two forms, one named MainForm that shows records from Customers in details view and the related Orders shown in GridView called OrdersDataGridView. The other form is called OrdersForm and is populated with the Orders table from the keydata dataset and shows records in details view.
When I navigate the MainForm customer records the correct orders are shown in the OrdersDataGridView. So far so good.

I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.
