There is one issue. If all of your clients don't close the application and you want to replace the .EXE, you won't be able to do it. Everyone must close the application (and not leave it running, lock the workstation, and go home!) before you will be able to replace it, if need be.

Reporting Woes...

My boss just gave a new task, one I am not sure I know how to address...

Develop a fat .net client that has a reporting component where the customer can create custom reports against an xml "dataset" retreived from a unix server.

Outputs PDF, XLS, HTML, print support support blah blah blah...

Crystal Reports, ActiveReports, ComponentOne? Not sure where to go for this?

Both canned reports and Ad-hoc reports must be supported on the client.

Licensing should be for free public distribution of course.

Since the app will be freely distributed via the Internet, Licensing and support are the big issues, other than the fact that the data will reside on a server and only the "resultset" will be returned by the server.

Guess I will have to write some sort of query tool as well.

Take a look at reporting services on SQL Server. It's free if you have SQL Server and might be what you need.

closing form

When I open 2nd form wrom 1st one with "Show" and then messagebox from 2nd form, then after closing 1st form the program hangs up. The problem is because messagebox is opened as a dialog from 2nd form. What should I do to close every window after closing 1st form?
I'm opening 2nd form with:
System.Reflection.Assembly assembly = System.Reflection.Assembly.LoadFrom("WindowsControlLibrary1.dll");
object obj = assembly.CreateInstance("WindowsControlLibrary1.Form1",true);
obj.GetType().InvokeMember("Show",System.Reflection.BindingFlags.InvokeMethod,null,obj,null);

Thanks for every help

So you have access to the control library or make a reference to that dll and then Just :

WindowsControlLibrary1.Form1 myForm = new WindowsControlLibrary1.Form1();<br />
myForm.Show();

this will close it whenever the main form closes.

Thanks but this still hangs up.
And I would prefere not adding references (I wont to load additional .dll's when program start).
I explain again:
|----| |----| |----|
| 1 | -> | 2 | -> | 3 |
|____| |____| |____|

I open form #1,
then from form #1 I open form #2 (Show),
and from form #2 I open messagebox #3.

When I close #1 the other two are still working.
Then if I close #2 and #3 the program is still running and to be seen in task manager.

Hope I explained everything this time.

Well, since Form holds the references to all the other forms, it can't close until all of its child forms close. Which, in your case, can't happen because your Form2 is stuck waiting for a mesagebox to close.

What you'll have to do is implement a status mechanism on Form2. In Form1's closing event, it has to check with all the forms it opened and ask each one if it is safe to close, and if so, then it can close itself after it closes each of the child forms.

Each of the forms that your Form1 opens has to implement some kind of method to track its own status. For instance, if Form2 opens a MessageBox, it has to update a flag in its code that says that it is "not OK to close". When the MessageBox finally returns, then it can change that flag to something that means "OK to close". When Form1 iterates through all the forms that it opened, it calls a function on each form that checks that flag. If any of the forms returns that it is NOT ok to close, then Form1 has to abort closing itself.

Help Me to port to Win98

How can i use application in win98. I used .NET Framework 1.1. I have instaled in win98. When i use that program, i got System.NullReferenceExpliction. Under xp, i don't have a problem. I have programd in C++ 2003

What exactly are you doing? It's not really clear if your using managed c++ or where the exception is being thrown.

Anyway some things like EventLogs don't exist on windows 98.

Have a look at this list[^] of supported features.

Saksida Bojan6-May-05 1:34

I Don't Use eventLogs

I use RegistryKey Does this support.

I din't find anything at that link

Dave Kreskowiak6-May-05 7:18

Some registry keys that exist under an NT Kernel (NT/2000/XP/2003) don't exist under 98. Your code should have been written to check return values before trying to use them. You'r going to have to go back and write some tracing code into your code so you can see where this error is taking place.

Without knowing anything about your code, what you're doing, where the error in your code is occuring, ..., it's impossible to tell you what's wrong. I mean, all your told us is, literally, "My program works on XP, but breaks on 98". There's absolutely nothing we can do with a description like this.

You're kidding, right? You don't pay me enough to debug your code for you, especially a chunk of code this long. I'm telling you how to find it yourself. You hope it helps me?!? No. Help yourself...

Let me show your what your NOT doing. I told you to check your return values before you try to use them. You're not doing that. For example:

RegistryKey *pKey = Registry::ClassesRoot;
pKey = pKey->OpenSubKey(S"ArtMoneyTable\\Shell\\Open\\Command");
Object *pValue = pKey->GetValue(S"");

Did OpenSubKey actually return a Registry object or is it null? You're not checking this. You're just assuming that it worked and returned the object you expected. Now, your next line immediately tries to use the returned object, calling its GetValue method. If OpenSubKey returned null, which exception do you think will be throw when you try and execute?

Object *pValue = null->GetValue(S"");

I'm not saying this is your codes' problem, but this is a glaring example of why your code is failing and you can't find where the problem is. Always check your return values before you try to use them!
