I'm somehow getting a double insert; every time I submit the form, it sends two records to the database. I can't figure out what's going on. This is a general idea of what my code looks like:Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click
'Data collection'
'Define Connection'
Dim myConn As New OleDbConnection

I'm trying to insert data from an Access unbounds form to an Access Table using the follwoing code:
View 2 Replieshere is my code so far:
Public Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
Dim i As Integer
[Code].....
when i click the button, i get a error message saying "Syntax error in INSERT INTO statement". as far as i can tell, i have everything i need to insert a new row into the database, and i dont see why this problem is occuring.
item(0) is an autonumber key field, so that should make a new record by itself, and i have declared the input textboxes as the data() array
How can I get access in a fast way to the single bytes that form a double variable?
In pseudo-code I want to do something like this:
Dim myDouble as Double
Dim myArray(7) as Byte
myArray = myDouble
'continue doing things with the single bytes
The code is meant for use in a I/O-handler. The double-variables have to be sent / received via TCP. For this purpose they shall be put into / assembled from I/O-buffers.
1st i get this error
query error and Conversion from string "Insert into Table1 (cust_id," to type 'Double' is not valid.
when inserting data to database 2nd error is
when use employee name to get employee id i got result always 0 here is the code
" select id from customers where name2='" & ComboBox1.Text & "'"
I have a login page, which a user will have to enter username, password and accesslevel. Accesslevel is either 1 or 2. 1 for admin and 2 for users who are restricted from using certain functions. I have this module set up so that I can make use of the accesslevel throughout the forms that I have.
Module ModuleAccessLevel
Public AccessLevel As Integer

Arjun taught me how to make use of this module, so now I know how to restrict users from using certain buttons, toolstrips by doing the following:

I built an app in VB 2008 Express.I have published it by using the Publish tab of the project properties dialog. In other parts of the publish dialog, I have successfully associated a file extension (.xyz) with my app. To finally publish it, I click the Publish Now button, not the Publish Wizard.The app publishes fine, and after installing it by clicking on the resulting Setup.exe file, it runs fine. The app creates a .xyz file (essentially a text file). I then close the app. In Windows Explorer, I can see the .xyz file with my custom icon. When I double click on the .xyz file, my app starts up.So far so good.
Now I need to implement reading the contents of the .xyz file in my main form's load event.I thought it was going to be easy by following a snippet to read the command line, and with the knowledge that the filename clicked on is the first argument (item 0 of the argument collection).So I started testing like this:
Dim strMessage As String
strMessage = "Count: " & My.Application.CommandLineArgs.Count & vbCrLf
For Each argument As String In My.Application.CommandLineArgs[code]....
So, is the method I'm using to deploy considered Click Once? Note that I am not online-enabling anything, so I am hoping I don't need to get into the ActivationUri learning curve, which seems to be about URL's.How can I simply get the name of the associated file double clicked on into my VB.net app?
I have a situation where I am handling both single & double mouse click events on a form. In both cases something has to be loaded, however when a double click occurs, I do not wish to execute the code attached to the single click event.Is there a way to intercept the mouse click's and check if double or single and then execute the right event appropriately?

I have a htpc project that I am working on. The main program loads dll plugins which are basically other win forms. On each of these forms, including the main program, I use a picturebox (a double buffered picturebox) for the background image and then draw everything on it by hand. Whenever I load the form from the dll and show it, I get a weird flicker. It looks like it is the previously used double buffer. Is there any way to clear the background double buffer before the flicker? Or am I going in the wrong direction?

For greater accuracy I should use a Decimal instead of a Double ( so I've been told ). Why then have Microsoft chosen to use DOUBLE for most of the functions that return a floating point value in the Math Class?

View 3 RepliesI am receiving syntax error in my insert into statement when I try to use try and catch phrase. The highlighted one is the cmd.ExecuteNonQuery() . What seems to be the problem in my code? I'm using autonumber for the ID so I won't put it manually. I am able to insert records when I don't use auto numbering but I need it so don't have a choice. For my database, I only have 3 fields which are AdminID, Username, Password.

I'm writing a program to work with access and one of the columns is an attachment data type. I was trying to use a INSERT INTO statement however it errors and tells me that INSERT can't be used for a multivalue field. Makes sense since an attachment type will allow for multiple files however I'm stumped how to make this work. Anyone run into this and if so what's the resolve? Is there a way to make .net make this happen programmatically? The only other thing I can think to do is save the file path or copy the file to another specified location and then save that file's path. To me that's not a good workaround and I'd like to use Access for what it can do.

With the DB table having an additional field called: itmID which is an Autonumber field so I dont need to add any data to this field.
But after the above SQL code has been executed I want to get the itmID number assigned to the new record - but I am not sure how to do this.
Im thinkin maybe using SELECT function but with WHERE filtering by the details I have just added but dont know if there is a simpler way.
