If I understand your questions correctly, here are the answers.
If you need to access a database from multiple forms, put all of the database code in a module and call the functions or subroutines from there.
The same answer applies to the functions: put them in a module.
Also, think about reusing the code in other projects. Don't hard-code connection settings, etc, pass them into the functions.

thanks that what i mean  
but i want to ask do i have to but it in form_lode sub and it will be visible to all functions and sub in the form
|

Add a seperate module to the application and make the functions/subroutines public. They will then be visible to the entire application.
The database access does not have to be done in the form load; it can be done wherever your application needs it.

What you are asking about (use better title) is a data access layer and it is a basic class/library every developer requires. Try some google research

I think the reason people marked this question as bad is because of the bad subject. asking... doesn't really tell us anything.

Hi
i wrote a function in MATLAB and made a DotNet dll using deploy tool of MATLAB. I imported this dll in my DotNet application and it works but my question is: is this necessary to have MATLAB installed on the pc or not. i want to publish my application but some one told me that this needs MATLAB on the pc!

I would expect so. I know what Matlab is, vaguely, but I don't know of anyone who uses it, bar students. I would say you need to test it, to be sure.

Probably, but you're going to have to test it to be sure. Otherwise, your best source of information is going to be a forum that deals specifically with MATLAB. CP is not that place.

And the technologies are:
Oracle Forms

Nope no VB for the VB forum.
Good luck getting an sensible answer for that question in this forum. You may do as there are a wide range of skills here.

You do not see it because that is one of the hidden files of the solution when viewing in the solution explorer. To fix this issue, highlight the solution in the solution explorer then in the menus goto 'Project' then 'Show All Files'. Although various files are different in different langauges this will work with C#, VB, and I believe C++. Their is also a shortcut to the 'show all files' in the toolbar at the top of the solution explorer.

Hello,
I am trying to understand the basics of XML, and I have a very simple idea which doesn't seems to be so simple  I used INI files before and decided it was time to try XML. But I didn't came further than
Dim xmldoc As New XML.XMLDocument
I have the following INI file which I want to store in a XML file:
[Settings]
WindowState=0
etc..
Can someone show me how to store this in a XML file?
I am using VB.NET and Visual Studio 2005.
Thanks,
--Zaegra--

One obvious example would be
<Settings>
<WindowState>0</WindowState>
</Settings>
I suggest you read up on what XML is, and how it works. You'll need to read up on XPath to be able to find your settings within this file, too.

I know the structure of an XML file, but I'd like to know how i can store these values in an XML file in the proper way. Could you tell me how to accomplish this? I searched CodeProject but i didn't really find what i needed
|
|
|
|

If I am using an XML source I use a dataset to manage the data in the app and read/write it using the dataset.readxml methods. This really is a nobrainer if all you want is to manage the data via xml. If you want to do any more then as Christian suggested you will need to devote some study time to it.

Zaegra - I did not want to imply nobrainer was personal. Dataset to and from XML really is simple to use but it will not give you ANY insight into using XML.
And yep we ALL started somewhere, I have almost no working knowledge of XML as I rarely use it.
However I have 1 strong caveat, do NOT use XML for transporting large volumes of data, XML is so verbose your data size will may become an issue. Use CSV instead.

The 'proper' way really doesn't exist, XML is a loose format, you can structure it any way you like.

Another method of handling this is with XMLSerializer, you use it to persist classes in XML. So you could have an INI object that you fill with data and then serialize it to disk, then when you want the data back you just de-serialize it. It is pretty simple have a look on msdn for code samples.
This way you can have a class that has the property WindowState, you then set this property in an instance of the class to 0 (obj.WindowState = 0) then serialize the object (something like serializer.Serialize(obj, path))
then just reverse this to fill the class and read its properties like any other class.
Hope that's of some use.

Hi
I’ve started to develop VB.Net application within the company I work for using Visual Basic 2008 Express Edition.
Working and testing locally I had no problem, but when I started to develop the application on my shared mapped drive I started get problems.
The first one was, when I loaded the project from the mapped drive a popup message stating:
“The Project location is not trusted
[PATH]
running the application may result in security exceptions when it attempts to perform action which require full trust”
I’ve been into the project security properties and set it to “this is a full trust application” and still not joy.
If I develop and build the application on my local machine and then try and run it on a mapped drive it fall over and crashes (Doesn’t even seem to start).
Does anyone have any ideas on how I can get around this?
Thanks

Network locations are not trusted by default in .NET. Only the local physical machine is trusted by default.
You have two solutions.
1. Tell .NET to trust the network location.
2. Strong name the assemblies and tell .NET to trust those assemblies.
The advantages of 1 are that you don't have to change the way you develop the assemblies, however it becomes a hassle if you have to change the network location - especially if you are running it on many machines (they all have to be updated)
The advantages of 2 are that you only have to tell each machine once and it will trust any assembly that has been signed with the strong name key. This means you can sign multiple assemblies and they can be run from any network connection. However, it means you will have to be careful with the key. If it gets in to the hands of someone malicious then they can use it to create assemblies that your machines will trust.
In order to tell each machine about which ever of the above routes you want to take you have to use the Microsoft .NET Framework x.x Configuration tool found in Administrative Tools.
