VS 2005 : Passing Command Parameters To A Data Access Class?
Mar 31, 2011
I've got a program where the insert/update SQL was created with the values coded directly into the SQL string. I've changed this to use the Command's Parameters.AddWithValue method and all worked well. I'm now in the process of separating the data access code out into it's own class. I've got the Select code working using a DataSet in the form that I pass ByRef to my data class so it can populate or refresh it. My sticking point is in how to pass the parameters for the Insert/Update commands to the class since from the form I no longer have access to a Command object. Do I need to make the Command object in the data access class available to the form?

We are using VB 2005(Visual Basic.net) with SQL server as database and MS Access for the Reports. Right now we are passing the footer label from our VB app to MS Access for a selected report. If the user closes that report(not closing access) and opens another report the footer label is not being displayed. Is there any way I could send the footer label to all the reports in Access as soon as I open the database.Right now in below code we are sending the footer label just for the report selected. Is there a way to send the footer label to all the reports that are existing in the Access database.
Here is the code we are using right now.
Public Sub printReports(ByRef trn As ITTransaction, ByVal blnPreview As Boolean)
Dim intSelectRptCnt As Short
Dim intI As Short
Dim strRpt As String

I've got a main form (Form1.vb) where I created some controls (with the Designer).I've created a class myTextBox, inheriting from TextBox, in myTextBox.vb.In the main form, I call procedures from myTextBox. The issue is, those procedures use values from the Form controls. So the class doesn't recognise them as initialised.What's the best solution for this?I think I could pass the object itself as a parameter but doing it on each call seems a bitredundant and it thickens the code.Is there any way to access the Form1 controls and objects directly from the myTextBox.vb class?

I'm tyring to pass a variable data type to a template class. Something like this:
frmExample = New LookupForm(Of Models.MyClass) 'Works fine
Dim SelectedType As Type = InstanceOfMyClass.GetType() 'Works fine
frmExample = New LookupForm(Of SelectedType) 'Ba-bow!
frmExample = New LookupForm(Of InstanceOfMyClass.GetType()) 'Ba-bow!
[Code].....
I'm assuming it's something to do with the template being processed at compile time but even if I'm off the mark there, it wouldn't solve my problem anyway. I can't find any relevant information on using Reflection to instance template classes either.
(How) can I create an instance of a dynamically typed repository at runtime?

I'd like to have a link on my VB form that will open an InfoPath Form with some information already pre-populated (name, date, etc.) with information that is already filled in on the VB form. I'm pretty sure there is a way to do this, just haven't figured it out yet.

I have a form with 2 dateTimePickers and a SHOW button which gets data from an sql server database and displays it in a DataGridView. this works ok. I also have an EDIT button which brings up another form with textbox and comboBox controls displaying this one record. I want to be able to click in the DataGridView to select a Name and then click on the EDIT button to bring up the selected record. I don't know how to pass the ID as a parameter to this second form. Apart from that the EDIT button works, in the sense that I hard coded the ID (32 or 35 etc.) and it brings up the appropriate record. But how do i pass the selected ID. [Code]

I have a DataSet1.xsd This is connected to my access DB through OleDB. the DataSet Designer is stating that my column in my table is of type Double. Which is true when I verify it by opening Access and viewing that same column in my table.
I need to pass a parameter to my fill query so that on formload it populates the controls. I create the parameter in the dataset designer and give the paramter a name and specify the proper data type.
I edit the query to include the parameter.
on form load the generated code from the dataset designer inserts the fill command for the table adapter but doesn't include the parameter data, so I manually insert the data to be passed to the parameter.. This is where I get an error stating that datatype mismatched..
However the datatypes are correct.

[code]This works fine and passes 8 parameters into the sysimp.bat file. The problem is if I try to pass in a value that has a space between the text then it will treat it as two parameters rater than one.So if P1 value is for example "Hello World" then when passed into the bat file it will assign "Hello" to P1 & "World" to P2. Is there a way to wrap the text in the parameters or should this be done in the .bat file?

I need to call a function in an unmanaged .dll written in C lang from vb.net. The function declaration looks like this [code]Now the behavior of this function is that it copies some data in argument "reply" and returns a numeric value which signals its pass/fail status. How do i pass it a string object so that it can copy data. Following is how i access this function.[code]When the call completes, returned status is absolutely fine but there is nothing in string "str". What is it that i am missing. I'm not sure about the string object that i am passing as argument.

I have a LINQ query:
VB
Dim Db = New MyDataContext
Dim Qry = From cust in Db.Customers
Select cust.ID, cust.Name
And I want to pass it to a function to filter it, like this:
VB
FilterAnyQuery(Qry, cust.ID) ' WHERE "cust.ID" CAN BE ANY FIELD
The Sub should be of this kind:
VB
Sub FilterAnyQuery(ByVal AnyQry As iQueryable, AnyField as ???)
AnyQry = AnyQry.Where(AnyField = "somevalue")
End Sub
How can I pass "AnyField" to the Sub and make the LINQ "Where" clause work?
