Hi guys,
Got a question for anyone who can help.
I have deployed an application I created in VB.NET on a client's PC. The application accesses a local Access database file. Everything works fine.
When I move the locally stored Access DB file to a shared network drive, and update the appropriate connection strings in my app to reflect this change, the app will crash when it runs the next time with the usual Microsoft Send Error Report dialog box appearing. It gives you a memory dump and a System Unauthorized Access error message.
The shared network drive has full read-write properties enabled for the appropriate user.
However, the trouble is that once it crashes, even if you change the connection strings and move the Access file back locally, whenever you try to run it from then on it still refuses to work and crashes. Uninstalling and reinstalling the app bears no results. The only way I have found to get it to work again is by going into the appropriate user's Local Settings folder and renaming or deleting the local configuration files.
Is there a setting or a permission I need to set to get it to work on the shared network drive? Do I need to alter settings in the .NET framework? If so, what do I need to change and where do I need to change it? While on my development PC in Administrative Tools there is a 1.1 .NET framework configuration link and 2.0 .NET framework configuration link, on my client's PC where I deployed the app there is only a 1.1 .NET framework config link, even though .NET 2.0 is installed. Examining the link on my development PC, I discover that it points to a file in ProgramFiles\MSVisualStudio8, as compared to the 1.1 .NET config link which points to Windows\Microsoft.NET\Framework. So how do I configure 2.0 .NET framework if I don't have Visual Studio installed on that machine?
I know I've rambled on long enough and I've probably bored you guys, but any help would be greatly appreciated. Thanx.
Regards, Alex.

in a local area network i need to captute all the packets that is sent by the clients to other clients.
then the server will put the required constraints :-
like i want to restrict a node to access for the internet between specific time (9am to 3pm...others can access but bot this node)
i have to keep track of each node to draw graph for each to show their average packets received and sent within last 5 mins, 1hour, day, month.
if i can get any help from you i will be greatful.

What bits do you need help with ? What have you already done ? Is this paid work, or homework ( I'm trying to get a feel for what resources you have available to you )

thankyou verymuch for your reply sir.
its not a pay project but its an academic project in our university for the completion of my course.
i have got the resources from our college. but am not getting a proper guide for this project.
therefore i would request you to tell me how to proceed in this project.
the time is very limited (30 days in hand)
thank yo once again

OK, well, if it's for your course, then your course materials should give you all you need to at least start your project. Google is also bursting with information. By all means, when you get stuck on specific things, ask here, and we'd love to help.

hello!i'm designing a software using vb .net that works with an antenna receiver to plot the radiation pattern received by the antenna. the software will read the signal/data sent by the receiver and plotting it.
Q1.so, how do i interface the software and the hardware?
Q2.how to save the data in obtained in a file?
Q3.after saved, the software is then display a numerical value based on the radiation pattern obtained?i mean, from the data obtained and saved we show a certain value..
thank you

Well, the parallel port is the obvious choice, although I think .NET 2.0 has support for the serial port, for the parallel, you need an external dll.
Q2 is trivial, once you have data, you save it any way you like. Same with Q3

I am trying to monitor the processes running on my system. i don't know how i can retreive the CPU use for each process. Just for ease of application, i am adding them the CPU Usage stats to a listbox.
So it would be lstCPU.items.add('here is where i have the problem')

Look into the system.Diagnostics.Process class. I think it's got what you need. You can get a list of running processes and a bunch of information about them.

Correct, this is what i'm working with, yet there is no member in system.diagnostics.process that pertains to process usage that i am aware of. Anything more specific or how do i go about using performance counters.

Hi all.
I have found a really weird problem, and have given up trying to find how to answer this. MSDN and the windows forms programming book just don't explain this:
I have build a type converter that implements saving complex types through the InstanceDescriptor.
The class works without a problem generating code for the design mode until you run the program. Once run, the type converter is broken. It cannot convert and I get that darned stupid cryptic message "cannot convert [type a] to [type a]"
does anyone have any thoughts or suggestions on what is happening here?
Thanks,
Tom

I messed around with a quick post i saw and found out that using casting in the type converters may cause crashes. I removed all of the casting and am now pulling the values from the object.
I also seem to be having trouble if i inherit from typeconverter, but have no problems from expandableobjectconverter
It works, but I'm really uncomfortable not being able to check a type prior to using it in the program. (granted it's only at design time) but still, I want to be able to do this.
Thanks.

Is it possible within vb.net2005 to specify where a messagebox will be placed on screen, e.g. x=, 7= ???
|

By default, a MessageBox is displayed in the center of the screen, and you can't change it's location. But, you could always create your own MessageBox via a Windows Form.
Trinity: Neo... nobody has ever done this before.
Neo: That's why it's going to work.

I have a subroutine that creates new pictureboxes when a user clicks a button. Here is a condensed version:
ReDim Preserve Picbox(array_size)
For index As Integer = 0 To array_size
Picbox(index) = New PictureBox
Next
For index As Integer = 0 To array_size
Me.Controls.Add(Picbox(index))
Picbox(index).Image = blip
Next
Now, I need to know how to be able to remove a picturebox, or otherwise manipulate the new pictureboxes. When I modify/erase pictures in the array, nothing happens to the pictureboxes on the form. How can I manipulate these new pictureboxes?
|
|
|
|
|
If you want to remove a specific picturebox according to your code, use dispose method as shown below.
Picbox(index).dispose
I think that should work! 
What a curious mind needs to discover knowledge is noting else than a pin-hole.

That does not work. The pictureboxes remain on the form.
|
|
|
|
|
Try Me.Controls.remove(Picturebox name goes here)...

You can iterate over your controls collection and find these different controls. Otherwise, you need to write the code to deal with them, one by one.

i think both not gonna work...
if i go for iteration
then i need to run the loops , i also thought abt same logic
but while writing into connection string u cant write label'i'.
it has to be no. only.
and i cant deal them individually
suppose i have to store for 200 hundred people..
i cant write code for individual case....
its nt feasable man....

There are no other options, sorry. How does a control Id go into a connection string ?
