I was afraid that was going to be the answer.
It would be easier having say Thread.CurrentThread.Exit(); but that
is not available...

I've put a sub main in my startup form, which I thought would be run on startup. But it doesn't seem to be. What am I doing wrong? Thanks
Public Class Form1
<stathread()> _
Shared Sub Main()
Console.WriteLine("MAIN SUB IS REACHED")
Try
Application.EnableVisualStyles()
Application.Run(New Form1())
Catch ex As Exception
Console.WriteLine("Main sub Error")
End Try
End Sub
End Class

Put the Sub Main in a module rather than a form.

A macro in what ? What does it do ?

The purpose of the macro is to connect to the internet site.
Any idea?

I still have no idea what sort of macro you're talking about, or how this relates to VB.NET programming.

Hello every one
I am working on a VB 2005 application which was originally a VB6 application and is converted to VB 2005 Express.
I tried using Microsoft FxCop to check the application, I am having following issues
- I was naming my objects with "_" in vb6 and all the objects which were created in VB6 are not showing any issues but all the objects created in VB.net 2005 were showing Breaking errors with very high Certainty
- I changed the name of Objects created in VB.net as per the naming convention of .net. Still I am getting a error asking to start the object prefix (lbl/frm/cmb…) with Upper case letters which is again against the naming convention of vb.net
- It is also having issues with the spellings of the object. Will that actually affect
- What about all the objects created in VB6, am I also supposed to change the naming convention of them also?
Can any one plz help me with this..
Regards
Nishkarsh

FXCop doesn't tell you your code is broken, only that it doesn't follow a standard that FXCop enforces. Why do you need to pass it ?

Perhaps if you could explain yourself a bit better ? Does table mean a SQL database ? You get data out of a table by querying it with SQL.

i'm doing a program using microsoft visual studio. each time i submit my data, it will generate a doc number that is in <yyyymmdd><custid><running number="">. My formula
docNo = System.DateTime.Now + kod + <running number="">. kod is the value from a text box. for running number, i have a function GetRunNo that will update a table in my sql database each time i submit a data. in the table there r 2 field that is run_no and date. Each time i click add button it will update the running number base on date, it will add the data in the database, and each data will have a doc number for our reference. how can i call the values in that table to put in the doc number?

I'm trying to add some generic analog and digital TV capabilities to a program, and I'm having some difficulties with DVB-T.
I'm using the MS Tuner Library, and the MS Video Control ActiveX, and am able to get correct image and audio for most cases... but I'm not able to find how to make an automatic scan function (already done this with the Analog TV but this one seems to be different), don't know how to get the provider and service name, and when I try to view one of the channels the msvidctl control doesn't show the image and crash, but the frequency, transport stream ID and service ID is correct.
Also, couldn't check how to select multiple languages so far (no programs with it right now), nor found anything regarding the Teletext display.
Any help?

I have a requirement to repeat a block of fields for each record in a dataset. This would be easlily done in VS 2005 ASP.Net with a DataGridView and a template column.
How is this done in Windows forms with VS 2005?? I had though that I could create a user control with the appropriate layout and add that to a list control of some sort...but there didn't seem to be any likely candidates.
Must one add the controls and do the data binding by hand?
Thanks for any help available.

Well I've discovered I still dont' know where to put a global try...catch block in vb.net. I figured it would go in the Mainform.mybaseload method but that doesn't seem to do it.
Thanks.

Hi again,
this is how it is done in C#:
static class Program {
[STAThread]
static void Main() {
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
try {
Application.Run(new myMainForm());
} catch(Exception exc) {
log(exc.ToString());
}
}
}
The above code instantiates and executes the main form class.
For a regular Windows app, VB.NET seems not to rely on a Main() method, but directly
launches the startup object.
However I trust in a VB.NET module you could do exactly what the C# code does.

Can I disable my try..catch block handling while debugging? Thanks
|
|
|
|
|
Nope. It's part of your code. You'll have to comment it out before you start the debugger.
|
|
|
|
|
Too bad..that's why making too many of them makes it difficult to debug.
|
|

|

Not really. It's how you break down your problems and what you put in the Try/Catch block that really matters. (Hint, hint)
Also, it helps if you're not putting the bulk of your method code in the Try block. Keep the Try/Catch blocks small, encompasing only very small operations. Say you have a method that queries a database, then loops through the returned recordset and sends an email to every address it finds. There's a ton of places this can fall on its face. Do you put all of this in a single Try/Catch block?? Nope.
Really, this can be broken down into a bunch more methods, each handling very small parts of the process. Creating and returning a connection to the database is one, exectuing an arbitrary query is another, iterating over a dataset, pulling email addresses out, sending an email to an address, ... These are all seperate methods, each with it's own Try/Catch opportunities. The more atomic the operation of each method, the better.
Luc just nailed it in his post here[^].

In my experience, it is not the number of the try-catches that poses a problem;
a lot of people seem to stuff the catch blocks with MessageBox.Show which is a
terrible idea, since now you get tired of reading messages, one at a time, and having
to close them over and over again.
I prefer to provide a simple "log" method that takes a single string input, and
logs it somehow. I then implement the log based on Console.WriteLine, a file operation,
a listbox operation, or whatever suits my needs at the time. The advantages are:
- I don't have to interact with this logging
- I get it all sequentially (I tend to automatically add a timestamp too)
- I can save it, and compare different runs
I often temporarily add a ListBox to my main form, just for showing the logging.
MessageBox really is not my prefered debugging tool!
