I have a form that allows users to select file and then it reads the contents, parses the data and then executes a sql insert statement to add it to a database. What I am having issues with is showing real-time results. Currently, I have the import operation take place on the import form within the OnLoad event. The problem with this is it only shows the final results instead of the results real-time. Is there anyway to do this without creating a seperate thread and delegates?
View 1 RepliesSo I have coded connection to database and query but when I push button nothing happens. So my question is how can I fix that Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I'm not sure how to do the following (in VB.NET), I'm hoping you will give me some insight or examples on how it can be done. My database is an SQL one.I have an assets table, which in it has the amount, growth percentage, income percentage. There are multiple assets per client.
I need to get the amount, growth and income into three separate boxes or variables and I'm not quite sure how to do this. The only other problem is that there would be two or three rows returned also, which need to have those three variables or textboxes again.
So for x amount of rows, I need 3 variables which the amount, growth and income will go into.
The reason I need everything into variables is that I can't find an effective way of showing each assets growth over x amount of years and the income it will produce into a data grid view. I'm able to do it if I specify what the growth and income are on the form, but not through the query.

I have the following code:
For Each control2 As Control In GroupBox3.Controls
If TypeOf control2 Is TextBox Then
Dim txt2 As TextBox = TryCast(control2, TextBox)
If counter > totalBoxes Then
[Code]...
What I am doing is looping through each textbox in groupbox3. Then checking if the counter(total number of grades that are inputted in the form) are greater than the totalBoxes(which is set to 0) and finally I am putting the actual grade(A,B,C,D) into the textbox. The problem is that it is starting the loop at textbox 8(I have 10 textboxes) for some reason and going from there. Does anyone know what the problem is with my code?

I have a form reading from an Access file now everything seems fine until i go to add record if i then press the first Btn or pre Btn without entering any data then it gives me the error Column 'Membership ID' does not allow nulls.

View 4 RepliesI have a from with a datagrid, binding navigator, and textboxes, nothing too fancy. This project is for a database management program. I am trying to have a messagebox show up if certain fields are left blank such as
If Ordertxt.Text = Nothing Then
MessageBox.Show("Test") ' This is just for a test
If CustomerTxt.Text = Nothing Then
CustomerLblERR.Visible = True
If Order_StatusComboBox.Text = Nothing Then
orderstatusERRLbl.Visible = True
[Code] .....
But no matter where I put a message box,(on cancel button, on random button on binding navigator) it closes down the form and goes back to the main form. As far as I know it is the only form this happens on.

View 1 Repliesyou know how you can set the windows taskbar to appear and disappear when the position of the mouse is all the way at the bottom? i want to do the same thing with my form when the mouse is in the top left corner of screen.or perhaps you can suggest to me a different way to do this. the user will probably just need to set those trackbars just several times during their usage.

View 11 Replieslast year i have written a simple application with a listview filled by a sql-server with patient data.When the application opens, then the actual month is displayed. Now i get the db-entries from last year not from this year.Here is the function:

Dim selStr As String = "SELECT ID, Nachname, Vorname, Dauer, Fachbereich, Datum FROM tbl_station11 WHERE month(Datum) = month(GetDate()) ORDER BY Datum"

I have written a code which adds some information to a database. No problem with that since the records get inside the database. My problem is that the record I added always shows up on my Search. I tried changing the variables so that none will have the same names between the two forms but it still shows.Example:
1. I added a record of a book which has an id of 1, name of Cisco, and total of 50. I added it thru the debug function.
2. I added a record of a book which has an id of 2, name of Link, and total of 30. This time, I added it directly on the database file itself.
2. I created a search button which will show records depending on the input of the user.If I type "1" for the ID, the first record will appear on the datagrid. If I type "2" for the ID, both records will appear. If I type "3" which I doesn't have any record with, the FIRST record will still appear. To summarize it, the record that I added through the program itself will always show up on the query results, no matter what I type into.

populate a simple combobox with a query to a MySql database. I Just want the combobox to show the results of the query:
SELET DISTINCT models from Cars
I am using VB 2008 with Datasets, how can I achieve this?
When I launch VB Help and do a search it shows under "Local Help", "Exception from HRESULT:0x8004032E". It lists three results under "MSDN Online", but the large field to the left of it is entirely blank. If I double-click blindly in that blank area it brings up various topics as if they were listed there but invisible. Further, the region under "Contents" is also blank, as is the "Filter by:" field. If I click the down arrow by the "Filter by:" field it brings up an entirely blank menu. If I then click outside the menu box it brings up a message saying "The selected filter contains an error that prevents it from being applied.". What's wrong and how can I fix it?
View 1 RepliesI uses datagridview for show query results from database which may have 0 to x number of rows. So I made calculation to calculate size of underlaying form and my datagridview dependable on number of matched rows. Underlying form is transparent and all of that looks like user control what appears and works just fine. But here is one issue: Every time datagrid have to grow, black square in that area is showed before datagrid is filled, what is not nice and surely unwanted. Did datagridview have some mechanism to freeze it and show data when populating is finished?

Alright it's been awhile since I messed with this project, so here goes. It's an appointment scheduler and everything works except two things: I can't edit existing appointments and it only records the current time, not the timeslot I click on.
If I try to edit an existing appointment it doesn't get the row data, just shows me blank text boxes. I assume I have to have those text boxes read the info from the database, but I don't know how to do that.
This is how it looks:
So, you double click a time slot and it looks like the second window. You can right click on an existing appointment to edit it, but when you do that all the text boxes remain blank like you're inserting a new one.
What code would I use to read whatever row's data I am trying to edit and insert it back into the boxes?
Here is the code I use to add new rows to the DB:
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click

I want to (SQL) select from a table in an Oracle database, and show the results of the query in the VB application, in a Excel like manner (rows, columns, selectable, etc.). Or in a SQL developer manner. How can I do that? Browsed through a lot of tutorials and howtos on the internet, did not get anywhere. I think (and correct me if I am wrong) that it's gotta be something with DataGridView. But I don't know how to create and populate a datatable with the result of as Select statement, how to create a dataset.

I have been working on a program (obviously) I have several textboxes and a webbrowser. I want this webbrowser to show a preview of what you have so far in these textboxes. Up to now I have:
For Each ctrl As Control In Me.Controls
If TypeOf (ctrl) Is TextBox Then
WebBrowser1.DocumentText = CType(ctrl, TextBox).Text + WebBrowser1.DocumentText
End If
Next
End Sub
When I debug it everything is ok until I press preview. I type hello in each of the boxes. By the way all textboxes are small and positioned close together. So I type H in one box E L L O etc and i press preview. And H only appears in the preview. I press preview again then H appears Once Again.
how to show let's say a word microsoft to 10 textboxes when i click a button.
