Hey Im having a problem with my calendar project and cant get my Mybase.new to work. This project is way over my competence and would be very greatful if someone could take a look at it.
Public Sub New(ByVal calendar As Calendar)
MyBase.New(calendar) <-------
_topsPassing = New List(Of CalendarDayTop)()
_backgroundColor = Color.Empty
_borderColor = Color.Empty
_oreColor = Color.Empty
_backgroundColorLighter = Color.Empty
End Sub
Im getting the error "Value of type 'WindowsApplication1.Calendar' cannot be converted to 'System.Windows.Forms.Calendar.Calendar"
The project is quite big so the problem might be somewhere else. I uploaded it on speedyshare if someone got the time, I would really appreciate some help.

You're trying to pass your Calendar class in the place of what your base class is expecting, a System.Windows.Forms.Calendar.Calendar. The two are not interchangable as it's saying that your Calendar class did not inherit from System.Windows.Forms.Calendar.Calendar.
You have to pass in a System.Windows.Forms.Calendar.Calendar, or something that derives from it.

And will be running on Windows 7 (32 or 64 bit).
Thanks before

Why on this earth are you doing new development in VB6?? It's dead and has been for quite a long time now.
|
|
|
|
|
Because vb6 has help me to get jobs and get money from it and have value for me, not mean we should forget it.
I create project with vb6 for small project, but now I am focus to the web programming like dot net and php.
May be another person can help me, please.
Thank you

Good luck! Industry support for controls for VB6 is just about completely gone.

In that case you better hurry to VB.NET, as VB6 is dead. It's no longer sold, and the modern platforms will not be built with VB6 in mind. Unless you still develop for Windows 95, it's time to move on..
..or become a part of history

I've been working around this for years and think it's time I finally learn something.
I need to implement what in MS Access would be a "Form_Current" event. An event that fires each time a new record is displayed from the underlying record set and *after* the controls have their values.
I've tried BindingSource.PositionChanged and BindingSource.CurrentChanged but they're no good because I can't rely on the controls actually having a value. Using the change event on each control (in this case) would be a royal pain because so much goes on when the record changes (things light up, bells and whistles go off, etc.)
What's the best practice?

I have a vb6 project with a form with a Apex TruedbGrid 6 Oledb datasource that has as an ADODC (Ado 6.0 sp6) on the same form.
cn.ConnectionString = "Provider=SQLNCLI.1;Data Source=pc-musica;Initial Catalog=QdE;User ID=sa;Password=*******"
In Form_Load :
Adodc.ConnectionString = cn.ConnectionString
Adodc.RecordSource = "Select Code, Description from Cantine"
Adodc.Refresh
When executes last statement Adodc.Refresh only on Windows 7 (because everything works quietly in Xp) gives me the error:
Login failed for the user, type: -2147217843 Automation Error.
I checked the connection string and it is also right when the program uses the same connection to open a recordset and operates quietly.
The connection is declared in a module.
How do you think I can fix on Windows 7 32 bit?

This is not my case. I don't change password e don't work with SharePoint

Well try another Google search for that error code.
Use the best guess

By moving to VB.NET; there's no guarantee that anything VB6 will work on the modern platforms. It has been dead quite some time now.

Did you register your TruedbGrid? And all the other stuff referenced?

I am getting this error when ever I want to add a second student to a form that has a Student ID that is Auto incremented. I first tried inserting all field to the database using the following code but failed to insert the Student photo and the enroll date properly.
Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click
Dim m, fe, F, P, H As String
Dim STPhoto As Image
Dim EnrollDate As Date
EnrollmentDateTxt.Value = Format(Now.Date, "yyyy-MM-dd")
EnrollDate = EnrollmentDateTxt.Value
Dim TA As StudentEnrollmentDataSetTableAdapters.StudentEnrollmentTblTableAdapter
TA.Insert(StudentIDTxt.Text, TelephoneTxt.Text, FirstNameTxt.Text, MiddleNameTxt.Text, LastNameTxt.Text, LevelTxt.Text, ClassroomTxt.Text, GuardianFnTxt.Text, GuardianLnTxt.Text, InstructorLnTxt.Text, m, fe, F, P, H, StudentPhoto.Image, DoBTxt.MaxDate, EnrollDate.Date, GraduationDateTxt.MaxDate, AboutStudentTxt.Text)
So I decided to use the dataset drag & drop feature to see if it can be helpful. It worked for the first entry but if I want to add another student right after the first one I am Getting the Concurrency Violation and the
Me.TableAdapterManager.UpdateAll(Me.StudentsListDataSet) is highlighted.
here is the full save button code:
Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click
If FirstNameTextBox.Text.Trim = "" Then
MsgBox("Fadlan Gali magaca hore ee Ardayga", MsgBoxStyle.Critical Or MsgBoxStyle.OkOnly, "First Name box cannot be empty")
FirstNameTextBox.Text = Focus()
Exit Sub
End If
If FirstNameTextBox.Text.Contains(".") Or FirstNameTextBox.Text.Contains("-") Then
MsgBox("Adeer Dhibic iyo xariixin lama ogala ee magaca hore ee ardayga gali", MsgBoxStyle.Critical Or MsgBoxStyle.OkOnly, "First Name box cannot contain (.) or (-)")
Exit Sub
End If
Try
Me.Validate()
Me.FulltimeStudentsTableBindingSource.EndEdit()
Me.TableAdapterManager.UpdateAll(Me.StudentsListDataSet)
MsgBox("Waxaad ku dartay 1 arday ", MsgBoxStyle.OkOnly, "One Student Added to Students lists")
Me.StudentsListDataSet.Dispose()
Me.TableAdapterManager.Dispose()
Me.Refresh()
I am not sure what
I am doing wrong as I when trough the code line by line and couldn't figure it out. I will highly appreciate if anyone can point me to what I am doing wrong. I even added an Insert Query into the table adapter to handle the table insert. Please help me if you can with any of my methods.
Thank you in advance.

Has it been set as a primary key in the database?

How do the update and insert-statements look like? Can you post them here?
Alternatively, you could try your luck on MSDN; How to: Update Data by Using a TableAdapter[^]

Yes its set as PRIMARY KEY as well Unique.
Quote: How do the update and insert-statements look like? Can you post them here?
I have posted this and here it is again.
Private Sub SaveBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveBtn.Click
Dim m, fe, F, P, H As String
Dim STPhoto As Image
Dim EnrollDate As Date
EnrollmentDateTxt.Value = Format(Now.Date, "yyyy-MM-dd")
EnrollDate = EnrollmentDateTxt.Value
Dim TA As StudentEnrollmentDataSetTableAdapters.StudentEnrollmentTblTableAdapter
TA.Insert(StudentIDTxt.Text, TelephoneTxt.Text, FirstNameTxt.Text, MiddleNameTxt.Text, LastNameTxt.Text, LevelTxt.Text, ClassroomTxt.Text, GuardianFnTxt.Text, GuardianLnTxt.Text, InstructorLnTxt.Text, m, fe, F, P, H, StudentPhoto.Image, DoBTxt.MaxDate, EnrollDate.Date, GraduationDateTxt.MaxDate, AboutStudentTxt.Text)
UPDATE: I created another Table with the StudentID not set as a primary key & Unique unchecked and it seems to work while its still Auto incremental set. I think It doesn't like the Auto incremental/primary key & Unique all at the set to true at the same time.
Can anyone tell me why My TA.Insert(StudentPhoto, EnrollDate) doesn't work?? StudentPhoto is set to Image and Enrolldate is using DateTimePicker. what am I doing wrong??
Thank you in advance.

My bad; the table-adapter is a class that does some magic in the background. It uses SQL-statements to do it's magic. I'd like to see both SQL statements. Those are the ones used to insert and update, the code you shown calls those in the background.
From MSDN[^];TableAdapters use data commands to read to and write from the database. The TableAdapter's initial Fill (main) query is used as the basis for creating the schema of the associated data table, as well as the InsertCommand, UpdateCommand, and DeleteCommand commands associated with the TableAdapter.Update method. This means that calling a TableAdapter's Update method executes the statements created when the TableAdapter was originally configured, and not one of the additional queries added with the TableAdapter Query Configuration Wizard.
When you use a TableAdapter, it effectively performs the same operations with the commands that you typically would perform. For example, when you call the adapter's Fill method, the adapter executes the data command in its SelectCommand property and uses a data reader (for example, SqlDataReader) to load the result set into the data table. Similarly, when you call the adapter's Update method, it executes the appropriate command (in the UpdateCommand, InsertCommand, and DeleteCommand properties) for each changed record in the data table.
I'd be guessing that the SQL-statement is either incorrect or incomplete, and it might be limited to having a single record.

You have failed to initialise some reference before trying to use it, hence the System.ArgumentNullException. Find out what line in your program that occurred on and fix the reference.
