DB/Reporting :: IP Address Not Displaying Properly In DataGrid?
Apr 9, 2008
I have populated a dataset with the contents of a csv file. Here is a sample of the imported data:
Protocol,Process ID,Process Name,Local Address,Local Port,Remote Address,Remote Port,Status
TCP,4,SYSTEM,134.190.220.54,4505,134.190.184.193,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3963,134.190.218.5,139,ESTABLISHED
TCP,4,SYSTEM,134.190.220.54,3816,134.190.176.154,445,ESTABLISHED
Here is the code that I used to import and display the data:
Code:
Dim sConnectionString2 As String
sConnectionString2 = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _
& CasePath & ";Extended Properties=""text;HDR=Yes;FMT=Delimited"""
[code]....
The problem is, all of the data gets displayed correctly except for the ip address. It gets truncated to "134.1892". How can I change the formatting for the "Local Address" and "Remote Address" columns.

I have a windows form with listboxes, buttons and a checkbox. It works fine at home but when I take it to school it doesn't display properly. I have been given full privileges and the .NET framework V3.5 is installed. I have all my buttons/checkboxes on the right hand side but they don't display like they aren't even there (there is no extra blank form space either). The form sized wasn't locked

Im trying to create a textbox where you must enter a value from 15 to 95; and if you dont you get a messagebox stating that you must do. Heres my code:
Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
Dim number As Integer
number = CInt(Val(TextBox2.Text))
If number < 15 Or number > 95 Then
MessageBox.Show("You must enter a value between 15 and 95", "Name Entry Error", _
MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
TextBox2.Focus()
TextBox2.Clear()
End If
End Sub
Whenever I type in one digit it automatically comes up with the messagebox. I know what its doing; its automatically reading the first number and not giving you time to properly enter anything.

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

I am working on a Data Survey Project and first I have a few questions about the different types of databases, and second, I need help querying my tables that have relationships.
1. I need a database that is stand alone. It is just the back end for the program. Simply to hold all the data an employee gets while out on a job. So would I be better using access, or SQL Express? I have played with both, but I do not want a large redistribution to my user machines. When I compile and produce this app does the SQL Database still work without installing any SQL Technology? Or do they have to go in after they install my app, and install Express?
2.Overview: I suppose depending on the first question regarding the database, it might change this question a bit, but none the less...I have 4 tables( using Access at the moment) I will be generating Reports based on data in the database. I haven't gotten that far yet. *Project* is the table that holds all the details that pertain to the job and client. It has a "one-to-many" relationship to *Survey*. So for one customer there are going to be many Survey Records. *Project Type* also has a 1-to-many back to *Projects*. Parts is kind of an orphan, but is linked to the *Survey* table with a one to many. So there can be many parts for one survey. I wanted this table for a drop down box, so the user could just simply select what hardware he was using instead of typing all the names and parts.
So in VS 2008 using the Designers and related Query tools, how do I constrain the Survey Data to one Customer? I have one form that opens from a button that is "New Project" and then there are all the *project* fields listed, so the user fills out the info and hits accept and that opens a new form called "frmSurvey" I need to add some code to the accept button to check what type of project is selected from the frmNewProject and then run a select query based on that. How do I write query statements in the code section of the form, without using the Visual Database tools?
Ill stop here, and get these questions out of the way first. If I could just get a handle on how to use the data properly with different forms and different controls with my queries, that would be great.

how to properly select a row or cell or whichever from a datagrid so that I can obtain the index value of the row properly. Below is the code.This code does select the row based on what is clicked on.
Private Sub dgAssets_CellMouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellMouseEventArgs) Handles dgAssets.CellMouseDown
If e.Button = Windows.Forms.MouseButtons.Right Then
[code]....
Now the only way that I end up with the correct Row index is if I left click the cell or row first, then right click. But using the code to select the row on a right click, for some reason doesn't set the CurrentRow.Index to what is actually selected.

I decided to have a go with Visual Studio 2010 using the VB language. Basically, aI have a windows form which shows a datagridview. The datagridview is filtered when the user selects a combo box. I then want the user to be able to e-mail the datagrid to a e-mail address. I've had a good look around the internet and found a way of sending the datagrid by HTML format. This has a few problems though - it doesn't look quite right (the columns aren't broken up by any lines) and the information isn't filtered (it sends everything that is stored it the datagrid).
Here is my code so far.
Dim oApp As Outlook._Application
oApp = New Outlook.Application
Dim oMsg As Outlook.MailItem
oMsg = oApp.CreateItem(Outlook.OlItemType.olMailItem)
[Code] .....
Here is what the form looks like when filtered.
Here is what the e-mail looks like.
So my question is, how do I get a filtered datagrid e-mailed?

I recently made a database that saves user information into a MS Access database from a form.
Code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSave.Click
objDA = New OleDbDataAdapter("SELECT * FROM CDetails",
[Code]....
Now when they go to the next form, I have labels such as lblFirstName, lblSurName ect. I want to display the information that the user has inputted into these labels. How can I fetch data saved into the database and display it onto these labels? and how can I select rows?

Take text data from a small file and display it in a form using a DataGrid.
I am trying to make the program so it will allow the user to choose which file to open (this part already works). I have stepped through the code and found that the rows are being added to the table, but when the action runs to completion my form has no data on it. Here is my code (forgive any code shortcomings as I have exactly three days as a VB.NET programmer).

I am trying to display an excel spreadsheet on a page using datagrid, but for some reason it is filtering out some of the cells, leaving a blank space instead. Also, the "$" sign won't show up in most of the columns.Could someone please take a look at my site and file, and give a suggestion as to why this would be happening? I've tried a bunch of troubleshooting on it, with no success.

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.

I have a problem with my datagrid(I am noob sorry if its simple). The datagrid is binded to a data table. What i want do is when a product is added or an existing one changed then make that one the selected row in the datagrid. The SelectionMode of the DataGrid is set for the whole row.
Here is the code that i am currently using,[code...]
Now as you can see from my code i don't understand how the index can be wrong as the datagrid is binded to a datatable and the indexes would be the same, and i have the current row in the datatable and look for the index in the datatable and stored it as a Integer!

I have taken up a task where end user should be able to enter information via vb interface into microsoft Access database. This then will be displayed onto the Datagrid via VB interface. The program needs to be setup in a way that first entry by end user will flash upon 3 hours.
Example:
VB Interface
=========
Basket Number | Number of Trays | Run Type | Time In
1 | 1 | CNC | 15:00:00
[code]....
Values defined within database shows in this datagrid.The Datagrid works fine and I can insert values into the database fine as well however, I am not sure how to setup a timer so that when 3 hours are up the first entry into the database(shown on datagrid) starts flashing.This is needed so that the end user gets an alert when the time is up so that he can take the trays out of the oven.
In Summary: Can we really setup a timmer so that a value in the datagrid will flash at a particular time.Below is the image of an application. Here you can see the data on the datagrid however I want it to flash after 3 hours. So the first entry will flash after 3 hours following the 2nd entry.

I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date.User can poplute these textboxes for multiple records and hit submit button.On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table.If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label.I got all this to work, but if it throws error message all the data in the grid is wiped out.How can i keep data in each textbox and still display the error message?
