You're not really comparing 'apples with apples' here.
My experience of Fortran compilers (admittedly over 20 years ago now) is that they are very highly optimized and geared towards crunching numbers. The .NET platform is not optimized for, nor was it designed for that putpose and has a whole lot more overhead.
Maybe you could find out what parts of the app are performing too slowly and attempt to hand-optimize the code or even break those functions out into another DLL written in C++ (for example) to specifically address the performance issues.

Thanks for the reply, for a while I thought I was up against my own stupidity factor  This a great help, have to scrap the project as it is though 
Thanks again, this takes a load off my mind. I do agree about the .dll solution for the number crunching, Lahey Fortran does allow the creation of dll's for use with other programming systems, that might be worth a look at.
OR complete recoding in C++ might be the answer?

I completely agree with Steve's comments - Fortran is a number-cruncher first and foremost .. so, if you want to compete and compare apples with apples, get yourself an optimized math library and get it to do the crunching for you

No. There is not anyone anywhere that has an example of that, as it is not possible. You can not use classes from the .NET Framework in VB6.
Look at the articles that Chandana Subasinghe showed you. They show how to call .NET code from VB6. All you have to do is write some .NET code to use SqlClient.

i wonder how to show an image by giving the location of the image and show in the picturebox???
like Path.GetDirectoryName(Application.ExecutablePath) & "\image\image1.jpg"
|
|
|
|

You have to import System.IO namespace before declare the class. Like
Imports System.IO
Public Class Form1<br />
.<br />
.<br />
.<br />
.
Then,
PictureBox1.Image = Image.FromFile(Path.GetDirectoryName(Application.ExecutablePath) & "\image\image1.jpg")

I am taking my first programming class in VB. I am working on an assignment that involves calculating a selling price with the cost sold of a vehicle and the results is suppose to show the total commission earned from the sell, total number of vehicles sold and the average commission and also a counter. Everything on my form works as designed except for my calculate feature.
If I can just get the calculation between the selling price and the cost sold to work then I think I can eventually figure out the rest of the coding. Can someone please point me in the right direction on how to code this issue?
Thanks

It means that you have not initialized an object correctly and its reference variable is still NULL.
Use the call stack trace provided in the message to pinpoint the code in error.

I have the following function
Public Function AddSheetCopy(CopyName As String, NewName As String)
For Each xlSheet In xlApp.worksheets
If xlSheet.Name = NewName Then
MsgBox ("sheet exists")
Exit Function
End If
Next xlSheet
MsgBox (xlApp.worksheets(1).Name)
xlApp.worksheets(CopyName).Copy after:=xlApp.worksheets(xlApp.worksheets.Count)
xlApp.activesheet.Name = NewName
Set xlSheet = xlApp.activesheet
End Function
It's pretty simple, I just want to make a copy of a worksheet, and give it a new name. Problem is it's not working exactly as it should. You will notice in the above code there is a message box to display the name of the first sheet, when running the code as above it works, but if you comment out that message box, it makes a copy of the current active worksheet.
Obviously I don't want to be plagued with this message box, but I am unable to make the function work without it.
Any ideas?

Hi All
I have a small problem that I hope someone will be able to help with...
I have a windows app that does a lookup in a DB table to find words that match in its glossary.
If the word finds a match in the glossary table, I want to have that word highlited (With a Clickable Link) in a RichTextBox so that the user can click on the link and another window will open up and display the glossary entry.
I don't have a problem doing the lookup. It's the inserting a link into the RichtextBox in the middle of plain text, for the word that has a glossary entry. I cant use the DetectUrls property as that is only for web links.
If you know how to do this, Thank you.
Otherwise if you know how to do this with a different control, please let me know
Thanks

Hi,
i am using a online dating site(a simple one). about images..is it good to store images in the database (ms sqlserver 2000) using ado.net
if yes i am continuing
my image uploads are working file now about managing images for user.
each user should be able to upload upto 5 images.
below are my codes
.aspx
----
aspx.vb
-------
Dim id As Integer = Request.QueryString("id")
objConn = New SqlConnection(dbPath)
Try
cmd = New SqlCommand("select * from userImage where userId='" + id.ToString + "'", objConn)
objConn.Open()
dr = cmd.ExecuteReader
'Dim img As Byte() = CType(cmd.ExecuteScalar(), Byte())
If dr.Read = True Then
Response.BinaryWrite(dr("bits"))
End If
Response.ContentType = "image/jpeg"
Catch ex As Exception
Response.Write("Oops what went wrong:" + ex.ToString)
Finally
objConn.Close()
End Try
--------
now the problem is
each image should have delete link which will actually delete the image and should be option like set image as primary pic.
in my aspx.vb if there is only one image rest of the images should be invisble instead of having img icon with no image.
please help me how to achieve this.
thanks in forward as i am just beginner in this area.
