Is there any particular order you need to follow to install
.net framework, IIS6.0, SDK, sql express 2005, msxml 6.0 parser.
Our network admin configured the server and I'm not sure if the configuration is correct. My .net application isn't working. Any suggestions?

IIS6 should have been first, MSXML 6.0, then the .NET Framework, whatever that SDK is, then SQL Express.

When you deploy a vb.net application to a server, does it have to be in the wwwroot folder? Also, if jpg's aren't showing on the application what problem might be causing that?

No. If you create another root in IIS, it can be created under a different folder. But, I've never seen anyone go through the trouble other than ISP's.

Usually, the wrong URL path specified in the HTML.

Sir,
I have created a windows forms control in which I put a DSO Framer control. I have compiled it and registered in GAC. Even its doing fine when I used it in another windows application. But When I try to put it in a web page its not showing anything as it is the same thing showing the required word doc in windows application.
Please tell me what are the steps do I need to take to make it fine. Thank you.

Please, PLEASE don't start cross posting the entire site again . This is an ASP.NET question, it's the ASP.NET part that is the problem. You've asked there, so leave it at that.

Hi all
I have to find all LAN Machines IP Addresses and machines name so can any body tell me hoe it is possible and which namespace and API i have to use for that.
Thanks & Regards

There is no namespace or API that will do this. You have to generate a list of valid IP addresses for your subnet, then try and PING each one of those addresses to see if it responds. Even then, the list you generate may not be accurate if a machine is at the address, but is powered off or in the middle of rebooting.

Has any one had any experience with this exception. From what I understand it involves a problem with the MSIL compiler and JIT. After googling the exception, I found that almost all of the cases were different in their beleived cause for failure and mine, like the rest did not match anyone elses.
Well, after taking apart the code line by line (This error does not let you execute the base method, stops before the method is called) I finally deduced where my problem was!!! I had used => in C# instead of <= comparative operand. The compiler did not pick this up as an error and just failed to operate the method containing this.
I am eager to find some one else who could see if this is just my machine or is it in the framework itself. Also, I would like to know more about this exception.

Can you post a code fragment with the => operator? I just tried to see if I could replicate it, and it's marked as an error during compile.
|
|
|
|
|
Yes I can, I created a quick one class program that throws the error:
class Program
{
static void Main(string[] args)
{
decimal testDec = TestErr();
Console.WriteLine(testDec);
Console.Read();
}
public static decimal TestErr()
{
decimal one = 1.555M;
decimal two = 5.8888M;
if (one => two)
{
one += two;
}
else
{
one -= two;
}
return one;
}
}
Also, it might help to note that I am currently using .Net 3.0 instead of 2.0. I could not replicate the results on my home dev machine running 2.0. I need to find some one else with 3.0 framework to see if this is where the issue lies or is it unique to my machine.
Thanks

=> is an operator in 3.0 for Lambda expressions. Are you confusing it with the >= operator?
|
|
|
|
|
No, I was tired and being sloppy in my coding and inserted => when I wanted >=. This mistake should have been caught in the visual studio 2005 environment as an error, but it built cleanly. I understand that the syntax was wrong, but it let me run with no errors. On my home dev machine, the interface caught this as an error.

Actually, the operator is valid, so the compiler may no capture it. You're probably not running 3.0 at home, because 2.0 doesn't have this operator, thus flagging as an error.
|
|

|

I am running 2.0 at home. So theoretically you can compare two values with a lambda(=>) expression? If not, this should have been recognized as an invalid argument and displayed an error. I understand that the syntax is used in 3.0, but is it used in the describe context?

Intellisense works by doing partial compiles of your code in the background, as you write it. The compiler didn't catch an error because there wasn't one. The expression is perfectly valid, it just doesn't do much except return the value of two.
You can find a little more on it here[^].

Which explains while it bombed at runtime - the if statement only accepts boolean results.

You got to be using 3.0 without knowing it. I just tried your example on a GUARANTEED 2.0 machine (it's never seen .NET 3 installed on it) under VS.NET 2005 and VS flagged the operator as an Invalid Expression before I even hit Build.

Yes, I am using 3.0 on the machine that threw the error, I thought I had made that clear. A coworker of mine ran it on his which is running 3.0 and did not get the error. So it's not a 2.0 or 3.0 issue. The only other difference might be linq or it might just be my machine.:->

I have a fairly standard forms-based application with a lot of data-bound combos (DropDownList style) in it. Everything works fine except when the form is used to edit a 'new' object. In that case, all the form fields should be cleared. But combos dont show in cleared state, they just keep displaying the first value in the list. So now the user thinks that a value is already selected for him, but the application doesnt actually update the bound property of the object unless some other value is selected in the combo.
Lets say I have these two classes in my app.
<br />
class SelItem<br />
{<br />
public string Id { get; set; }<br />
}<br />
<br />
class MyObj<br />
{<br />
public SelItem Selection { get; set; }<br />
}<br />
To fill the drop down list of the combo i use (Id is a string property of the objects im passing through valuesList):
<br />
combo.DisplayMember = "Id";<br />
combo.DataSource = valuesList;
and using the forms designer I've bound the Text & SelectedValue of the combobox in this way (bindingSource contains a list of MyObj):
<br />
combo.DataBindings.Add(new System.Windows.Forms.Binding("SelectedValue", bindingSource, "Selection", true));<br />
combo.DataBindings.Add(new System.Windows.Forms.Binding("Text", bindingSource, "Selection.Id", true));<br />
Currently, I'm clearing the combo-boxes by setting their SelectedIndex property to -1 every time a 'new' form is launched, but thats just a hack. Anyone got an idea why isnt the combo taking care of this automatically.

I am having problem regarding debugging MMC application which is developed using C# and .Net version 1.1. Currently I have installed .Net version 2.0 and now if I try to debug the application it starts normally and when I try to add an existing snap-in using Add/Remove snap-in option of MMC the application closes without any error. If I run the application in release mode it works fine.
If I uninstall .Net 2.0 then I am able to debug the application but I don’t think this is a good solution.
If any one have faced similar problem or having any idea regarding this issue please help.
Regards,

I want to convert an application written in VB.NET into a Window service. I tried an example which writes to the event log every 10 secs. Following is the code i wrote in a timer's tick event:
Dim MyLog As New EventLog() ' create a new event log
' Check if the the Event Log Exists
If Not MyLog.SourceExists("MyService") Then
MyLog.CreateEventSource("MyService", "Myservice Log")
' Create Log
End If
MyLog.Source = "MyService"
' Write to the Log
MyLog.WriteEntry("MyService Log", "This is log on " & _
CStr(TimeOfDay), _
EventLogEntryType.Information)
The timer is enabled in the OnStart(). The Service got installed using the InstallUtil command. And I was able to start the service. But this was not my requirement. I tried to display a message box instead of writing to Log. So I replaced the above code with a line to display a messagebox; ie it brings up a messagebox every 10 secs. The service got installed but it did not start. It brought up a dialog saying "The service returned no error. This could be a problem with the internal Windows....". I tried writing similar code like showing a form but all returned the same problem. But it works with code written above but if it contain any MsgBox then the problem occurs. Is it possible to write pure VB code in a Window Service?

A service is usually run under the System user account. There is noone logged in using this account, so there is nowhere that the service can display any user interface. Even if you run the service using your own user account, it might not be able to show a user interface. A service is not supposed to have a user interface.
If you want a user interface for your service, write a regular program that monitors the service.
