Another question would be how do i declare a statement as a string if that statement has "" in it?
I believe you double the quotes, as in
String s = "Marks = ""69"" Grades = "C"""
In C#, it's \", but I believe it's double quotes in VB.

I need explorer to open a folder so that i can view the files inside. No browsing or dialog box is needed, I just need to open that specific folder with Windows after clicking a button. Anyone knows how to do this?
I'd say that ShellExecute or Process.Start will do this, just pass in the path.

Dim str As String<br />
str = "Marks = ""69"" Grades = ""C"""<br />
Where ever you want to put quotes inside of a string use ""
So this --> 1 "2" 3 would be coded as "1 ""2"" 3".
EDIT: Christian and I posted at the same time.

Anyone can help me? I try to import data contents on .csv to .sdf (SQL SERVER CE).
Best Regards...

What's an sdf ? You want to move a csv into a SQL Server database ? If you know the format of the file, create a table that follows it, and INSERT all the rows into it.

I am getting an error when debuging a program that is: "An unhandled Exception of type 'System.Runtime.InteropServices.COMException' occurred." I also see in my Event Viewer: Event ID 10020 Source DCOM. "The machine wide Default Launch and Activation security descriptor is invalid. It contains Access Control Entries with permissions that are invalid. The requested action was therefore not performed. This security permission can be corrected using the Component Services administrative tool."
This is what I have in my source code: "Dim xlBook As Excel.Workbook = xlApp.Workbooks.Add"
I have tried to give EVERYONE access to the "Microsoft Excel 97 Application" in DCOM. This had no effect on the code.
I would appreciate any suggestions or solutions for this issue.

Hags,
Try wrapping your code with Try/Catch (see example) to trap the error and see what additional information it gives you.
Try<br />
Dim xlApp As Microsoft.Office.Interop.Excel.Application<br />
Dim xlWkBk As Microsoft.Office.Interop.Excel.Workbook<br />
<br />
xlApp = New Microsoft.Office.Interop.Excel.Application<br />
xlWkBk = xlApp.Workbooks.Add<br />
Catch ex As Exception<br />
MsgBox(ex.Message, MsgBoxStyle.OKOnly, "Error")<br />
End Try<br />

Hai,
I have seen the use of
Public sub new()
in VB.net.
What is the use of that?I will apreciate if somebody can give me a brief idea about that.
Similarly what we can use in C# instead od Public sub new().
Please show me the right way.
Thank You,
Rahul

Public Sub New() is whats called the constructor for a class in VB. In there, you can set variables to default values, or other stuff thats required for the class to work properly.
C# is a little different...
|
|
|
|
|
C# uses the class name for constructor with no return type.
public class MyClass
{
public MyClass()
{}
}

Hai Danie,j4amieC,

I am writing an ASP .Net Web Application using VB .Net 2003. I would like to create a modal web page or dialog box so that I can have my users add additiiona information. I know that in Java there is window.showModalDialog but is there a way in VB .Net to do this?
Thanks
Charles

No, there isn't. ASP.NET is a server-side only technology that generates HTMl for a browser. You'll have to use JavaScript for this.

Dave,
Thanks for reply. Jon, I'm sorry but I don't get your comment. I am new to VB .Net and WEB developement. After working with VB 5 & 6 I wanted to make a jump to ASP .Net Web Application through VB .Net 2003. Some coding is very easy, others I am having problems with (like this). Why not be able able to have a page ontop of another like "Click here to add notes"?

Because the capability just doesn't exist in a browser. Can you imagine the problems with popup ads if it did!
ASP.NET (regardless of the language it's written in!) doesn't generate any executeable code for the client side. The sole exception being JavaScript for the HTML page's controls to report back to the server.
If you want to put up a modal dialog, you'll have to include JavaScript in your HTML page to do something like this. I have no idea how to actually do it myself. That's a question for the ASP.NET Forum, not VB.NET.

I am trying to implement a login screen and would like to verify the user has permission through novell.
Can anyone point me in the right direction for code examples and what kind of information I would need to get from the it administrator.
Thanks in advance

Novell's support for VB.NET is poor at best. You can use the ActiveX controls to do this, but all their examples using those controls are in VB6 last I checked. Find everything at http://developer.novell.com[^].

Most "Real World" applications are linked to a database server. I need to create a app that is a stand alone and can be deployed on a MS windows based OS.
What is the correct way to create/deploy a VB.net or CS.net application that needs a database file to save/retrieve information.
Application is Porsche GT3R data acquistion module.
All data is converted to numeric or character data
DB must be reliable and slightly scaleable. Excel,Access,WFS?
Network does not have SQL2000
Target PC does not have SQL2000
Which database should be used to create a deployable app with a file that contains less than 5000 records and each row is 300 btyes long.
This is a simple data entry/retrieve system that is not networked to a DB Server.
Please give input or point me in the right link direction.
Thanks again

I'd recommend access for your needs, you don't even have to have it installed to use an mdb file through ado.net.

Hi,
I don't have much knowledge of the table control. I am basically trying to use a table thats populated with data rows from a dataSet but currently things aren't working for me.
below is the sample HTML that I have:
<asp:tablerow>
<asp:tablecell text="Company" id="CompanyCode" runat="server">
<asp:tablerow>
<asp:tablecell text="Paygroup" id="PaygroupCode" runat="server">
<asp:tablerow>
<asp:tablecell text="paygroup descr" id="PaygroupDescr" runat="server">
------------
In addition, I think I need some VB code but I'm not sure of the syntax:
Table1.ID("Company") = Dr("Company")
Any help would be much appreciated.
Thanks,
Gavin

You need to check 'Do not treat <'s as HTML tags' for your html to be visible.

 Thanks for pointing that out.
<b>Here is my html</b>
<asp:TableRow>
<asp:TableCell Text="Company" ID="CompanyCode" Runat="server"></asp:TableCell>
</asp:TableRow>
<asp:TableRow>
<asp:TableCell Text="Paygroup" ID="PaygroupCode" Runat="server"></asp:TableCell>
</asp:TableRow>
<asp:TableRow>
<asp:TableCell Text="paygroup descr" ID="PaygroupDescr" Runat="server"></asp:TableCell>
</asp:TableRow>

As I thought - this control just generates a table, as in a html table. It's not a databound control. You need to use a datagrid or a repeater to do this. Then the datagrid will generate the table for you, using the data source.
