Hi,
I am using VB.NET 1.1 and I am having difficulty in finding a starting point in my array. My array is filled with Product objects. Lets say I want to start at row 301 and display all the products till row 600, how do I do this?
I have the following, but I don't know what to do further:
ByRef productArray As ArrayList (this is a parameter to this function.
Dim p As New Product
Dim i As Integer
For i = intStart To intEnd
For Each p In productArray
Response.Write("SKU: " & p.ID)
Next
Next
Please can someone help me??
Regards
ma se

For i = 301 To 600
p = productArray(i)
Response.Write("SKU: " & p.ID)
Next

Thanks Colin,
I was wondering if the same could be done for a SQLDataReader, using .NET 1.1. I have all the records in a datareader, and I am supposed to read in 300 records at a time. Depending on the page number. Page 1 should display records 1 to 300, page 2 should display records 301 to 600.
After populating the data reader, is it possible to start reading from a certain record?
Thanks

No a data reader cannot be navigated in a random access way. You need to read in the first 300 rows and discard them. You would be better filtering that out int he SQL query you sent in the first place.

After changed OS version, my applications run wrong cause of regional settings(date ,time and currency formats). Is it possible to fix the bug without recoded entire application source?
Thanks a lot

I doubt it. You haven't posted any code samples, but it sounds like you wrote your code without any regard for the culture it's running under. For example, you may have used your own custom formatting strings and used the Format overloads that don't take a IFormatProvider object to provider culture information.
There's no little "switch" that's going to fix that for you. It's going to take a complete code review to add in culture tolerance into your application.

I have created a stored procedure in MS SQL Server. It worked well there, but I want to call it from my vb application by sending a parameter to get the result from the database. Who can tell me how?
Thankz

Did you mean: How do I do this?
If I answer "Who can tell me how?" then my answer would have to be "I can" - but that is not very helpful to you. Is it?
The SqlCommand object has a Parameters property. You just need to Add your parameters to it.
e.g.
cmd.Paramters.Add("@SomeParameter", someValue)

I would just like to add, that for .NET 2.0 the Add method has been deprecated and the method AddWithValue should be used instead (with the same parameters).

That is not entirely true. Only one overload of the Add method has been deprecated. The remaining overloads are acceptable.

Hi,
I am returning many rows from my SQL statement, and there are only 2 colums. How do I add these columns to an ArrayList for each row?
Regards
ma se

Look, an ArrayList can only have one column...
But in btw, why do you want to put in an arraylist...

Typcially, an object that is represented by a row in your database is represented by a class or struct in your code. So, you create a collection of that object.

Hi,
I am developing a client server application where I need to generate a report in Excel (instead of Crystal Reports.NET). The formatting and other cell attributes need to be controlled through my VB.NET code.
What is it that I have to do?

Hi Vinod,
One possible way to go: create an excel file (in Excel) with the formatting the way it needs to be. Open the excel file with .NET Studio. It will show you the file in xml form, including the necessary information concerning the formatting. Then use your code to manipulate the xml file's formatting and fill in the tags that you want. In the end save the xml file as .xls, and you are done.
Good luck,
Johan
My advice is free, and you may get what you paid for.

Hi Johan,
What is the process of opening this Excel file in .NET studio. Seems a pretty dumb question but how do I do that?

Hi Vinod,
Not a dumb question, I forgot to mention that you need to save the file as xml (spreadsheet) in Excel. Then you simply use open file in visual studio. In other words you open the file as an xml file. In your code it is then very simple to save the file again as .xls

I have migrated an application from vs 2003 to vs 2005.Everything works fine,but when i create the installation setup and deploy the application on some other machine and try to generate crystal reports i get an error "Absolute Path information required".Also when i installed the same setup on the machine on which visual studio is installed the reports are generated.
I have added all the merge modules.All the pre-requisite to the application.The database bounded to other forms is getting accessed.One more thing i would like to tell you is that even when i create new repot and new report viewer control on new form,create setup and instal the setup same problem is there.Everything works fine except reports.I'm really bugged up with error.
Let me tell u what all things i tried.
1.Adding all the 4 merge modules.
2.Changing the installation path.
3.Given TableLogOnInfo
4.Giving the absolute path during report load.for ex. crpt1.load
(Application.startuppath & "\Reports\abc.rpt")
5.Tried Changing the registry programfilesdir .
6.Create New report in the same application with new form containing new
reportviewer control.
7. I tried to modify the overridable property ResourceName abc.vb (crystal report
file).But then i get error "Unable to locat resource i the manifest"
Following is the code on the Reportviewer Form
Friend Sub UserList(ByVal strSql As String, ByVal Headers As String)
Try
Dim objRptUserLog As CrystalDecisions.CrystalReports.Engine.ReportDocument
objRptUserLog =new CrystalDecisions.CrystalReports.Engine.ReportDocument
objRptUserLog.load(Application.startuppath & "\Reports\rptUserlog.rpt"))
Dim tbCurrent As CrystalDecisions.CrystalReports.Engine.Table
For Each tbCurrent In objRptUserLog.Database.Tables
Dim oLIInfo As CrystalDecisions.Shared.TableLogOnInfo
oLIInfo = tbCurrent.LogOnInfo
With oLIInfo.ConnectionInfo
.ServerName = DatabaseConnection.GetServerName 'SETTING SERVER NAME ,UID,PWD,DATABASE
.UserID = DatabaseConnection.GetUserID
.Password = DatabaseConnection.GetPassword
.DatabaseName = DatabaseConnection.GetDatabaseName
End With
tbCurrent.ApplyLogOnInfo(oLIInfo)
Next tbCurrent
CR.DisplayToolbar = True
Dim crFormulas As CrystalDecisions.CrystalReports.Engine.FormulaFieldDefinitions = Nothing
Dim crFormulaTextField3 As CrystalDecisions.CrystalReports.Engine.FormulaFieldDefinition
Dim strDate As String
crFormulas = objRptUserLog.DataDefinition.FormulaFields
crFormulaTextField3 = crFormulas.Item("Header")
strDate = Headers
crFormulaTextField3.Text = "'" & strDate & "'"
CR.SelectionFormula = strSql
CR.ReportSource = objRptUserLog
Catch ex As Exception
MessageBox.Show(ex.Message)
End Try
End Sub
If anyone has come across this problem before and solved it please help me.I tried searching on different sites but did not get any help as such.Please help its very urgent.
Thanks & Regards,

hi,
the pcs on which the crystal report was showing errror of "Absolute Path information required",i removed windows os and reinstalled it.Now everything is working fine.Even crystal reports are getting generated properly.I think some components must not be getting updated.

Is there a tool to generate VB code from a .REG file. I know I can import bulk registry keys with running REG IMPORT or creating the code manually. Although the latter works fine for a few settings, I would like to have bulk settings done from within the code.
|
|
|
|
|
Not that I've ever seen.
There are external utilities that will import the .REG file for you though, like RegEdit[^], of course.
