VS 2008 SQL Command With Join Function?
Oct 1, 2009
this is the statement:select ITE.stock from orderdetails ord join ITEquipment ITE on ITE.product = ord.productnamey goal is to retrieve the stock from ITEquipment depending on the name of the product which has to match from orderDetails table. when I try this on the SQL SMS I get stock in two records of stock (for some reason 2 not 1, I should get 1)and then I try to use it in my application it returns a full set of records from orderDetails table instead of one record from the ITEquipment.

I've found alot of examples for add/edit/delete a single table. In VB6 ADO you could load multiple tables into a recordset using the join command. Then manipulate or modify the data.
I've found how to retreive multiple tables like,
Da = New OleDb.OleDbDataAdapter("Select groups.groupid,groups.userid,lots.groupid,lots.lotid from groups inner join lots on groups.groupid=lots.groupid order by groups.groupid asc", DB) But the only way I have found to update is to use seperate Update commands for each table.

Dispatch has column 'DispatcherID' and 'TechnicianID' which are both foregn keys to EmployeeID in Employee table.I want to join these two tables using EmployeeID so that i can obtain the matching name to each id.but it only works when i make a single join to either DispatcherID or TechnicianID and not for both.

What value will be returned from below execution with select, insert, update, delete?
Dim L_EXECUTED_NO1 As Integer = command.ExecuteNonQuery()
Dim L_EXECUTED_NO2 As Integer command.ExecuteReader()
Dim L_EXECUTED_NO2 As Integer = command.ExecuteScalar()
For example, I tried "Dim L_EXECUTED_NO1 As Integer = command.ExecuteNonQuery()" with Update SQL statement and that returned "-1". But it returned 1 for Delete SQL statement.
If Query_SQL("EXEC SP_ATT_CLOCK_INOUT_UPDATE '" & L_TODAY_DT & "', '" & L_EMP_ID & "', '" & L_START_TM & "', '" ) = True Then
MsgBox("Successfully saved!", MsgBoxStyle.Information)
End If

Right now I have a listbox, this listbox displays surnames, when clicked it displays their address. I have a 'confirm' button to confirm the right person. And now I need more information to come up when that's clicked, giving data from another table. I'm sure I need to use an inner join but I don't quite understand how to do it

I don't know where the extra character 'N' is coming from, there should only be one parameter coming from my SP which is the ID:
cmd1 = oStringConnection.SetCommand(sqlConnectMain, _
cmd1, "TestStoredProc", _
DBConnections.myType.cmdAsProc)

Similar to using VAL(a$) to return the numerical value of a string, is there a function for returning the solution of an equation that is user-typed into a textbox? For instance, user types F$=(a+b*x)/(c*x^2-d*x^3) where the variables of the equation are either pulled from a textbox or derived within the code. I am looking for something like F=Solve(F$).

Here's a sub routine that fills a data set with a table which I queried using an Inner Join statement. This output table, has all the required fields and the query works fine. However I want it like so:
If a student doesn't have a StudentPrediction.PredictedGrade Field to JOIN and it IS Empty.. Then I still would like it to display the students information just leaving the StudentPrediction.Predicted field empty.
You see I am using a ListView to display the data from when I fill the ListView, but it will only display for people who have a Predicted Grade naturally. So what steps would I need to take to ensure it displays all the information in the Student's table AND for the students who do have predictions that would also be displayed. If the student has no data on PredictedGrades then that column would be blank but the rest of the information still displayed.
Private Sub FillDataset()
Dim ConString As String = ("Data Source=USERSQLEXPRESS;Initial Catalog=StudentTeacherDB;Integrated Security=True")
Dim QueryString As String = "SELECT Student.FirstName, Student.Surname, Student.Email,

dsNumbers.Relations.Add("compare", _
dsNumbers.Tables("dtVDEOutputNumbers").Columns("jobno"), _
dsNumbers.Tables("dtCSRInputNumbers").Columns("vg_jobnum"))
DataGridView1.DataSource = dsNumbers.Relations("compare")
No data seems to be returned from this command, even though I know there is data present. There is one record per table:
dtVDEOutputNumber: jobno = "24383", vde_pkgs = "328"
dtCSRInputNumbers: vg_jobnum = "24383", vg_quantity = "650"
Not sure why it isn't matching and return a "Joined" record.

I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")
This process runs through analyzing, runs it in normal mode & prints the progress to the command window.
My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.

I am trying to send a command to the external command line (cmd.exe) from the Windows form application that I'm writing in VB.NET (using VS2008).
I can only access the external program thru the command line (its not my program) and I must do so from a form app.
I am trying to use the following code. I am able to call a cmd.exe window, but I can't pass the command line my command.

I am using a CheckedListBox that is populated with Filenames (full path, i.e. C:TestTest.jpg)When I have the files that I want in the CheckedListBox I wish to click a Start Button which will process the list one at a time using an exe program that runs on the Command Line. There are arguments that need to pass to the command line as well as the file location in order for the program to process.I currently have it working but the issue is the loop finishes quickly and it is left up to the CMD.exe to finish the process. What I would like is for the LOOP to wait until each file completes processing before passing the command for the next file in the CheckedListBox.There some reasons I wish for it to work this way.
1) I would like to have a button that can Pause/Restart the Loop.
2) I would like to have a button that can Stop the Loop so the whole process can end.
3) I would like to have the Loop remove each file one by one from the CheckedListBox after it has been processed.
4) I would like to display a Message once all the files have been processed.
5) And if it were possible I would like to report the status either by text or a progress bar showing where it is at in the process.
6) And the ability to add some error handling if possible.
Since the Loop finishes so quickly as it just passes the command to the command line using the & as a seperator it is the command line that is handling the rest of the process. Because of this there is not control over it in the GUI.The code I am using allows the Command Line text to display in the Form so it won't open up a seperate window to run CMD.exe. This is the desired affect as I would like everything to appear to run from within the Form itself.

User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
