Get Columns Names From Table And Pass Parameters Dynamically?
Sep 14, 2011
I am trying to figure out how to do this or if it is even possible. I believe it should be, I have about 20 different tables with different amounts of columns in each table. I.E. One table might only have 4 columns while another might have 30 columns. What I am trying to do is create 1 sub/funtion that will handle the select and import for all 20 different tables, unfortunately for me I can't seem to figure out how to write this.
I know the select statement for getting the column names is :
SELECT column_name FROM INFORMATION_SCHEMA.Columns where TABLE_NAME = 'table'

I'm trying to produce a repeater showing amounts of money taken by various payment types into a table.Payment types available come from a global settings file as an array, I am creating a dataTable by looping this list and extracting sales reports (there might be a more efficient way than this loop, but this is not my concern at the minute).My question: How do I bind this to a repeater and display it when I dont necessarily know the table column namesI've tried various methods to give the table a header row and give the columns numerical names from a for > next loop, but am either getting no results, orystem.Data.DataRowView' does not contain a property with the name '7'. < or whatever numberThis is where I currently am:
EDIT: JUST REALISED MY CODE WAS AWFUL, SO UPDATED:
Dim paymentTable As New DataTable("paymentTable")
For j = 0 To UBound(paymentTypes)

I'm writing a query to select all records that has any part of parameter. I have one table called Employees. Some people have name like this: John David Clark If the parameter is
[Code]....
I should be able to get result back as long as there's a match in the parameters. If I use Function Contains (q.FirstName & " " & q.LastName).Contains(employeeName), I will not get any result back if employeeName is "John Clark" Function Contains looks only for next words from left to right. It doesn't match a single word at a time. So that's why I used this in the Linq to SQL:

I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

For x = 0 To xyz123.Tables(0).Columns.Count - 1

I've created an exe that is a ticket management system for in-house debugging, etc... It uses the same database that is accessible via MSAccess. In order to create a seamless work environment, one of the supervisors wants employees to be able to see data from the tables the exe uses without actually opening the exe and looking up the record. That's no problem since it's all the same db, but they also want to be able to open that ticket with the click of a button...instead of opening the exe and doing the search themselves, they want to just *click* and have the appropriate ticket open in front of them. I have no clue where to even start to do this....

I have a bunch of methods that do some formatting on data that is contained in a structure. I'm passing the structure to the methods as a parameter. The problem is that the same structure is returned from 2 different webservices depending on the program flow (I did not create these services and cannot change them). So at one point I would be passing WebService1.Service.MyStruct and later I might have to pass WebService2.Service2.MyStruct.
Is there a way I can write only one method to handle both type of parameter? The struct is the same and only differs by namespace. I can overload the methods but I was wondering if there was another way to do this with reflection or something along those lines.

Just kind of curious about something: why does VS (vb and C#) default params to pass-by-value?I almost never need or want to pass anything by value. Maybe this is some reflection on the way I code. I would never manipulate a value type param directly; i would just return the new value from a private variable... and I just don't see the need to do the background work all the time to add copies of everything to the stack. Why wouldn't I just about always want to pass-by-ref?

we have an old vb6 application (let's call it app-vb6) that basically handles database searches. now i created a new .net application (app-dotnet) that can use the database information to do something else.
what i want to do is to be able to run app-dotnet using information obtained from app-vb6 (which would send something like a command line with a few parameters). but i don't know how to make only one single instance of the app-dotnet to refresh information every time app-vb6 calls it. this link [URL].. seems to have the answer but i could not follow it since it is VC.

This code calls a store procedure that takes input parameters. With this code I'm confused as to how the parameters are passed to the stored procedure. The parameters are first stored into 2 string variables (strCategoryName & strOrderYear). They are then copied/moved to an sql parameter prm.value. But the stored is stored in an sqlcommand (cmd ). I can't understand how the stored procedures knows what the parameter values are.

I am calling a XML web service (standard web service project based on .NET 3.5) and trying to pass custom types as parameters. The custom types are defined in my consuming code and the web service references an assembly from the consuming code to get access to the types. The serialization is being handled by .NET.
<WebMethod()> _
Public Function MyMethod() As MyType
Dim myValue as new MyType
return myValue
End Function
In my consuming code I created a web reference to the service and the proxy classes were created. I gave the service the namespace "WebService". Next I try to make a call to the service and assign the result from the call to a variable, something like this:
Dim service As New WebService.ServiceNameSoapClient
Dim response As New MyType
response = service.MyMethod()
I get an error from the IDE saying that it cannot convert type mynamespace.WebService.MyType to mynamespace.Entities.MyType. It appears to me that although the types are similar they are being treated as different because of the different namespaces, which makes sense of course.
Edit: So from what I am reading I believe this is by design, that is the proxy types are simply different types and cannot be directly associated with the types in the consuming code.
