I have a sql stored procedure with an output parameter. I'm just trying to read the output parameter in my code and I just cannot get it to work. The error I get is: "Procedure or function 'GetFolderData' expects parameter '@RootName', which was not supplied."
It looks like I am supplying this but it's not working.

I'm creating a tool using windows form which needs to retrieve data from an Oracle database configured to use odp.net using an Oracle Stored Procedure. I'm planning to use the code below for some basic testing. The Stored Procedure is made up of a number of OUT parameters, some of which have been mapped using the datatypes available in .NET, however other parameters are defined as tables (I guess lists) and i'm not sure how to access this data
Try
Dim oraConnString As String = "Data Source=*****;User Id=******;Password=******;"

We have an c# class, say we have a following method with out parameterpublic class TestCsharpClass{ public Int32 GetNumber(out bool pbNull){ pbnull=true; return 1; }}tlb file for C# project is generated with regasm tool. The above method is called in vb6 application using callbyName Dim number as IntegerDim objTest as TestCsharpClassdim blnNull as Booleannumber = CallByName(objTest,"GetNumber",VbMethod,blnNull) return value 'Number' is fine.But 'blnNull' boolean variable is "False" always.We were unable to get the out parameter value from C# code.Function signatures are defined in the IDL file.Without changing the function signature is it possible to get the resolution/workaround solution for this issue

I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.
in my SQL 2005 database I have defined this stored procedure:
CREATE PROCEDURE [dbo].[CheckOrders] (
@PK_Customer uniqueidentifier,
@Amount bigint OUTPUT)
[code]....
When I check the value of nAmount it stil contains the original value -1 the output value didn't return from the stored procedure although the number of records updated is 0 or more. The procedure was checked, it works and there are records updated and the value of @Amount is SET to a value 0 or more. I just don't get the values back. eventough the parameter @Amount is defined as OUTPUT. I also tried with outParam.Direction = Data.ParameterDirection.InputOutput instead of outParam.Direction = Data.ParameterDirection.Output . Same result. How do I get the value back from the stored procedure?
How can i check if an output parameter is null before i bind it to a asp literal, and if it is null i want to just make the literal [code]...

View 2 RepliesI'm in the process of switching my application from MSSQL to MYSQL. When I was using MSSQL, I retrieved the last auto increment value via
Private Sub dsImpoundInformation_Inserted(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceStatusEventArgs) Handles dsImpoundInformation.Inserted
_impoundId = e.Command.Parameters("impoundId").Value
End Sub
[Code]...
ultimately, I'm just trying to get the last auto increment value but there are other sections of my code in other applications that I plan on switching to MYSQL that depend on output parameters. I have't yet explored using stored procedures but at this time I would like to get this to work in a similar fashion to how I had it with MSSQL.

My application uses a third party API. This API uses a few functions that returns a value by reference as one of the function parameters. Problem is according to their documentation, the value I am trying to get out of this function is a string pointer.
So if that made no sense, heres an example of the syntax of the function as shown in their documentation:
long ExampleFunction(long ID, long PropNum, char* name, long MaxStringLength)
Input Parameters: ID, PropNum
Output Parameters: name, MaxStringLength
Thats pretty much all the info I've got. Obviously they are not using VB.Net, looks like C to me. I want to get the name output parameter and work with it, but once I get this value, I cant change anything. I know this is because its a pointer (reference type?) but I am still at a loss as to what to do.

I have some code that let's a user upload a csv file, and then generates an xml file to download. Basically they select a file to upload and then click generate xml file. Right now, I'm doing all of that in one swoop. What I want to do is just upload the file, then stop the page request and tell the user I'm generating the xml file for two reasons. One, it interrupts the page load so I don't have to set the timeout higher and two, that way the user knows it's

I am hardcoding an insert statement to a database, based on certain details a user enters into a windows form. The form has a few textbox and datetimepicker controls for the purpose. This form enters a single row in a single table in the database.The table has a few possible null columns defined, in those cases where the user does not have any data for those columns at that particular time.
I have to provide controls for passing data to those null columns nevertheless. In my case, I have two such columns that accept null values, and two corresponding controls - a textbox and a datetimepicker. The datetimepicker has a checkbox added to it so that if it is supposed to be null it doesn't pass the default current date value, and remains unchecked to explicitly specify that it is supposed to be null. By default it is unchecked.
My code is structured as follows:
Form1:
'the sub referenced here resides in a dll file in my dataaccesslayer code, and in my actual example is referenced properly.
'I have shortened the code here for simplicity

Now it gives me an error whenever the code comes to the executenonquery(), and says something to the tune of "SqlDateTimeOverflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM."
I think the value of 'Nothing' from the subprocedure's paramter is not being assigned to the sqlcommand's parameter as a database NULL, which is what I need to pass to the database.I know instead of using optional parameters I can easily create overloaded subprocedures where one sub allows not passing values where the column(s) is supposed to null and other overloaded subs permit combinations of which column(s) are null or not. But it is simple as long as there is just one, or at the most two null columns in a table. If I have dozens of null values in a table that the user can choose to enter or not in a data entry form?

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]
