I have an Employee form that displays data about the employee, on that form I have a button that launches an Employee Job form that shows data about the employee job.
My question is how do I show the relevant data on the Employee Jobs form when I click the Button on the Employee form?
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.
Whenever I use this code, I get a File Not Found exception, even though the file paths are all correct. [code]...

I want to launch an .exe file from my resources.?
View 1 RepliesI wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

I have a program in which I want to have the user enter two percentages and display the data matching the criteria on a new form. The query would be:
Select *
From Corrosion
Where corrpct1 >= {column in database} OR
corrpct2 >= {column in database}
The way I currently have it written is to display only one row of data. I need to display any number of rows that meet this criteria. My current code is:
Private Sub btnDetails_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDetails.Click
Dim form As New frmDetails()
Me.Hide()
[code]....
1. How can I do my query to incorporate the user entered criteria (in the where statement)?
2. How can I display ALL of the data instead of just one line?

I'd like to use a TreeView control to display database data in a windows form with VB2008. All the information what I found is related to a website design, but I'm working on a database program (sql2005), where I'd like the user to see the structure what he/she make up with a TreeView like control. Just something like that when you explore your hard disk. How can I do that?

View 2 RepliesI need to quickly demonstrate a project and decided to create a user control that is connected to an Access database through pure simple data connections (create the dataset and drag it on the control.)When I build the project and add the usercontrol to panel control on the main form, no data is shown in the datagrid.When I add the data components directly on the main form, the data is displayed properly. why I can't get my databound user control to display the data on my main form?
View 2 RepliesThis is what I'm trying to accomplish: I have a Point of Sale application that integrates with a credit card processesor. I wan't to remove any user interfacing logic in regards to the credit card processor in the point of sale and add it to a application that sits in the background or system tray. I want to be able to send a command to the background app to popup a form for user input.
For example: User in the Point of Sale clicks a button "Credit Card" at this point it will send a command to the background app say "ProcessCC" which will pass a transactionid and an amount , this will open a form for the user to enter in the credit card information and submit the payment to the credit card proccessor.
Reason: I need to get a padss certification and don't want to submit the point of sale to do it. Rather send the simple background app that will control any credit card processing functionality such as encryption , storing etc. I know it can be done using sockets but was hopping for an alternative solution.
I am working on a project. Part of my project requires me to capture data, for example, email address, from certain rows/columns of a datagridview(form2.vb) and displays them in a textbox on another windows form(form1.vb) with a click of a button(Add Contact button). The problem is the datagridview on my form must be able to display databases by making a connection to Microsoft SQL Server 2005 but so far, i have not been able to do that. I have seen many codes with regards to my problem but i do not know how to implement it.
Below are my codes that i have written so far. My program's limitations are not being able to display databases from Microsoft SQL Server 2005 so i created the statement below to add columns and test my codes.
DataGridView1.Columns.Add("CustName", "CustName")
DataGridView1.Columns.Add("Email", "Email")
[Code]...
I would like to know how I can make this happen?
When I double click on a row on a datagrid, a form will appear like the above screenshot.
When I double click on the row which consist of Brian/Kendall, a form will appear and should show Brian in the First Name text box and Kendall should appear in the Last Name textbox.
At the moment I'm using:
For Each book In books
result.Add(File.ReadAllText(book).Substring(0, 500))
Next
Return result
to display the first 500 characters of an rtf file I'm drawing from in earlier code, but I'm now wanting to specify line - for example lines 4 - 20.I can't find any way to get this to work as when I change the above code to:
For Each book In books
result.Add(File.ReadLines(book).Substring(4, 24))
Next
Return result
I get massive issues stating "Substring is not a member of 'System.Collections.Generic.IEnumberable(Of String)" I feel like I'm literally 1 line of code away from this being fixed but cannot get my head around it.
