I have form1 and form2. On form 2 i have 2 combo boxes where the user is asked to make selections. once back on form1 i try to use those selections as part of an if statement but although i should be triggring them it does not. I cannot figure this out. I have set up test variables and msgboxes along the way to test this.
The code excecutes. I have double checked the variables on form 2. They just do not trigger a response that will enter the if statements even though it looks like they should. I have double checked that test1 and test 2 are grabbing the variables from form 2
test1 is "Male"
test2 is "10 - 19"
When the code excecutes i never get to the msgbox("Age") line of code. I have also tried taking the spaces out of the strings with no luck as well.
MVC3 VB.NET application. I have the below section of code in a function. This code is supposed to only fire if the handout1 is not nothing. But for some reason it is going into the then block when the handout1 is nothing in the database... I have tried a hundred different ways of checking but it is still trying to run that line of code even when there is nothing to assign to it....
I am creating a feature in my application that will allow a logged in user to add additional users to be logged in. The usernames and passwords are kept in a single database created in Access 2007. The table has 3 columns: ID, UserName, and Password. I am trying to insert user-inputted data through a TableAdapter function in a DataSet. It has worked once but for some reason it stopped working, and I can't figure out why.
Calling the TableAdapter function... Me.UsersTableAdapter1.AddUser(Me.txtID.Text, Me.txtUsername.Text, Me.txtPassword.Text)
[Code].....
Visual Studio isn't throwing any errors my way or anything so I am not sure what's going on here. The fact that the code worked once but isn't working now is also confusing, and I don't recall making any changes related to this feature since it worked that one time.
Conversion failed when converting the varchar value '17, 18' to data type int. Which is the same error message I get when I run my application. So I guess somewhere along the line, when passing those values in the parameterized query, they are being passed as string literals with quotes around them, instead of integer values separated by commas. How do I add the string that I obtain as the argument for this subprocedure into my sql query's parameter such that they do not get passed as string literals with quotation marks around them?
I made a smallprogramm. Each Q is at the top of the Form.vb right under the Public Class.Each A is declared in the Private Sub where the given A is matched with the stored Q. Each A looks like this: DIM Answer1 As String = "Answer" and so on. I would like to use just one DIM statement for all the answers.
I need some help working with an OleDbCommand Statement existing statement
OleDb.OleDbCommand("Select *, (([AddressDisplay])&', '&([City])) AS Address
The City is stored in database with the city name and an additional abbreviation added. I need to get rid of the abbreviation, if possible.I DONT control the database its from a 3rd party.
Example: Houston[HST] I need to remove the [HST]
Can this be done? Either in the command statement of perhaps in the displaymember of the combobox that reads the database?
I'm running into a slight problem with an SQL INSERT INTO statement. I've tried setting this up first as a command statement and now as a stored procedure. When the process runs it's not signaling any errors and it appears that it's working properly. However when I check the database nothing new has been added. I have the statement within a try catch and it's not catching any errors. I've gone so far as to delete the table and recreate it, still nothing. I should also point out that this entire statement was essentially a copy & paste from another program that's working perfectly.
vb.net code below
Code: Try Dim cmd As New SqlCommand cmd.Connection = con

I am converting old VB6 code to VB.NET with ADO.NET (OleDB). This is my query that will create a blank table when ran in VB.NET, but then works when ran directly in Access. This code presumably also works in VB6, as I am using the same SQL:
SELECT qryAsOf.name, qryAsOf.type, 0 as opt, 0 as swap INTO qryCon FROM qryAsOf LEFT JOIN qryLinked on qryAsOf.c = qryLinked.lc
I feel like this has something to do with the left join and select into being together, but like I said it is only VB that has an issue with it, Access handles it perfectly.Without the INTO line, this query returns all 600+ rows.
This DOES NOT WORK:
cm.CommandText = "CREATE TABLE qryCon (etc...)" cm.ExecuteNonQuery() cm.CommandText = "INSERT INTO qryCon SELECT ..." '(rest of query above without INTO line) cm.ExecuteNonQuery
This DOES WORK:
cm.CommandText = "CREATE PROC qryCon AS SELECT ..." '(same select as above without INTO, again) cm.ExecuteNonQuery
The CREATE PROC that does work is fine, except I need to insert data into it later, so I get errors about how I need an updatable table. I really want the end qryCon to be a table, but I can't seem to get that to work :(
*However, when I do something like this (using the stored proc (renamed) above which, if viewed in Access, is full of data)
cm.CommandText = "SELECT * FROM storedProc" dr = cm.ExecuteReader
[code]....
This DOES NOT WORK! By the way, I removed the concatenation in the query for readability. It is correct in the actual project.
I have a line of code that is working in one statement but not the second statement. I'm not sure what I'm doing wrong, I am learning slowly but surely, and it is by no small margin because of the ave found here =) The error is occuring in the intResult = intSelection x intCount line of the SECOND Do While Loop.
The blue squiggle line is under "intCount" just FYI Dim intSelection As Integer Dim intCount As Integer = 0
Syntax error (missing operator) in query expression '''system time'''.this is the error that appears
this is my code:
Dim sqlCmd As String Dim x As Date x = Format(Now(), "General Date")
[code].....
the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.
[URL]I'm making a bot to submit a form multiple times. I want to add "public int count" and "public int max" to limit and count how many entries I've had.I can't find out where to put it though, I know in the class but where? When I put it somewhere it says end of statement!

I was using an If block to see if a line in a file contained a specific string. But I need to look for many different string and do different things based on each. So I don't want a million nested If blocks. So I decided to use a Select statement. But, I can't figure out how to use .Contains with it. If I do .ToLower.Contains, like I did in the If block, it stops me.
VB.NET For Each _line In lineList Select Case _line.ToLower
What is the best way to run an if statement if I have text in my textboxes?I have 6 textboxes,textbox1 will always have text but how would I do this?[code]
I need to pass four parameters to a SQL statement and i'm using the following code. It works fine for the first parameter but ignores the rest without erroring.

Firstly Case 2 runs. Throws exception. And right after this debugger shows that next processed statement is Case Else. Only after Case Else throws own exception Catch block start working. I've never seen this trick. Why can this happened?I'm sure the block is entered once (not like this:first enter hit Case 2 and second hit Case Else).
Update:-To Matt Wilko. Thank you for answering. I've switch to Strict On in Options of VS2010 but nothing has changed. Command is variable, not function. Watch tool shows that on each step Command is the same ( Command = 2).
Fixed. Yeeaaaahhh. I simplefy code to Try Select Case 2 Case 2
[code]....
and change project to Console app. This works as I mention. The fix was in Release mode. I was debugging in Release mode. When I switch to Debug mode everything goes as it should.
The value of strDateTime_Stamp is #1/19/2011 9:42:22 AM# I'm getting an error ( "ORA-01830: date format picture ends before converting entire input string") because I don't know how to correctly assign the AM/PM tag on the end -- you'll notice it just says "MM/dd/yyyy hh:mm" in my code. I've tried a bunch of different things but nothing works. I also find it odd that if I change the "MM/dd/yyyy hh:mm" to "mm/dd/yyyy hh:mm" (little m for month) it gives me a 42 for the month value, not a 1. The capital M's fix that but I'm curious to know why.how to I get it to show the AMPM on the end?
I have a windows application. I would like to run a statement while exiting my application. I tried adding my statement on FormClosing event. but it only executes if the application is closed properly. However, If the application is closed via task manager or system is restarted or logged out, etc. then the statement in closing or disposed event is not getting executed.
Private Sub Form1_Disposed(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Disposed MsgBox("disposed") End Sub Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles Me.FormClosing MsgBox("closing") End Sub
can some one tell me how to get my statement executed even the user tries to log out or shut down or application is closed via task manger.
How will I insert the output of my DataGridView to another table in the database? I have 4 Columns. The First and Second Columns are Check Boxes. The Third is The Stockholder Code. The Forth is The Stockholder Name. What I want to happen is, my selected records(The Stockholder Code, The Stockholder Name ) via check boxes will be inserted in my database.
Here's what I've done so far:
Try For Each row As DataGridViewRow In DataGridView1.Rows Dim cell As DataGridViewCheckBoxCell = CType(row.Cells("checkboxchild"), DataGridViewCheckBoxCell)
