Because the app doesn't use WMI to get it's information, it has to use the Win32 API function GetSystemFirmwareTable[^] to get this kind of information. There is no support for it in the .NET Framework BCL. Beyond that, it's a custom read of physical memory locations.

O thank you!!! For this moment I didn't know a way(instead of WMI of course) in getting hardware information and etc.Later, I want to test this API function on Visual Basic 6!!!! I think it will work!!!

I'm just learning VB.NET and am writing some code that will poll the network and display status boxes within a form. This works fine using something, displaying a nice status strip kinda thing about 50 pixels high (+ the title bar).
But ... Now I come to rotate the form to show it vertically, and find that it seems to have a minimum width which is rather wide !!!
I find that setting the MinimumSize doesn't help. And trying to set the width in the code doesnt help either. It wont get smaller than 123 pixels. This restriction is also experienced in the Design window if manually creating a form.
If I remove the minimize box and maximize box from the form I can resize it to a narower size when the program is running (around 65 pixels), but the 'size' function wont take it to this width.
Now I guess there is something limiting the narowest width that you can chose for a form, but it does seem rather daft.
Maybe I shouldn't be using a Form, but it does everything I want. I have searched the web and the forums and can't see any reference to this restriction, which makes me think I'm missing something obvious !
Please help put me at rest and get me thinking about something else.
Thanks
Nigel

Probably because a small form like that is seldom ever used. Try changing the FormBorderStyle to SizableToolWindow or FixedToolWindow to see if that gives you what you want.

Oh my !!!!!!!
Thats exactly it !!!
I can't believe it. All those days of searching and it was that easy (for you of course).
Much appreciated, your my hero for today.
Please award yourself a gold star.

I programmed a windows service that sends email alerts based on database returns... The problem is as Follows..
Background:
When I loop through the records I am building a large string (i.e. Result += ) for a mailmessage.body and including the HTML tags ... The record lengths are of various sizes and always random.
Issue:
My issue is when it sends the message, the string is split up after 989 characters and a ! is entered in the string... If the ! is in the middle of text it is not as much of an issue... I just see a ! in the mail message; but if it is put in the HTML Tag the message goes to Cr*p...
Does anyone know how I can prevent the ! from being placed in the string or another method to avoid this..
Thanks in advance

Step through your code that builds this string and watch to see what the ! comes from. If you get through your code and just before you call Send, it's still not in your string, it's probably being inserted by your mail server.

It is not in the string prior to the send function... Where do I go from here if it is put in by the mail server?
|
|
|
|
|
It's possible that there is a line length limit on the mail server, it's just a Telnet session after all... Try adding CarriageReturn characters in appropriate places in your string instead of making it one very long line.

Hey Guys,
I made an application in which i had used dynamic generation of picture boxes. I have one picture box and the dynamic generation of the picture boxes are duplicate of the one that i already have. Even then the performance is really not good and it takes hell lot of time for the thumbnails to load in the picturebox.
Is there is good logic that i can use for this. Anything that just loads up everything instanetaneously?
Thanks !!!

The performance of the PictureBox is dependant on the ORIGINAL size of the image your stuffing in it. If you're telling the PB to load an image from a file that's, say, 3000x3000x32bits, it'll take a while to load, even though your probably scaling it down to fit in a box that's 100x100.

IF you are doing anything non-trivial with images, you should abandon the picturebox, and draw it yourself. And yes, use the DrawImageUnscaled method for speed, and make sure your image is the right size, so you don't waste memory.

Try to separate what you write into sentences, so that it gets readable.
Expect replies in the forum, not in your mailbox. The intention of a forum is that people can collaborate to find answers, and that other that just you may benefit from the answers.

Yup, I am a newbie to the forum and to VB.Net. I am doing a window application for school assignment. I need to make a app with (First Name), (Last Name), Books overdue,Amount overdue. Also, I need 3 buttons, one for (Exit) (Clear) (Calculate)Here is the directions..
You are to create a Visual Basic.NET application consisting of a single form that will do the following:
1) Allow the user to enter the student’s first name and last name in separate text boxes.
2) Allow the user to enter the number of books that are overdue.
3) Allow the user to enter the number of days the books are overdue. You may assume that all books were checked out on the same date and are due on the same date.
4) Calculate the fine by multiplying the no of days late by $.25 by the number of books.
5) Display a picture of a book on the form. (BOOKS03.ICO)
6) Clear the text boxes so the user can easily enter the information for the next student.
7) Display appropriate Tool Tips for each of the controls.
8) Display a sentence containing the student’s name (first and last) and the amount they owe (formatted for currency) in a label. (e.g. Joe Blow owes $3.75 for overdue books.)
9) Provide buttons to allow the user to calculate and display the fine, clear the form, and exit.
Special
Considerations: 1) All fields must be clearly labeled and have access keys to allow keyboard access.
2) When you clear the text fields the insertion point should automatically position to the first name text box.
3) Focus should follow a logical tab sequence.
4) The escape key should exit from the program.
If i can get some help here please, I would appreciate it. I really have no idea on the code stuff. I am lost...Please Help..Thanks

You're going to have to narrow down what kind of help you're looking for. Just posting your homework assignment will probably get you some snide remarks, but little else.
What, specifically, are you having a problem with?

Thanks Dave.
What I need is a tutor I suppose, The assignment calls for a windows application, but I am new to this and cant figue it out. It is the code part.

Why don't you start by creating a new project and select windows application as the type of project. Drag some labels and textboxes from the toolbox to the form, and you are already on step three without writing a single line of code.

The core issue here:

Your school will have offered you the resources to do a lot more than just post the assignment to the web. If, once you've exausted those options, you're stuck, by all means post your code and ask *specific* questions. We don't do people's homework here, but we're glad to help those who are doing it themselves.
Sadly, most of this is not programming at all, it's playing in the IDE settings. *sigh*

OK, Thank you..I wantnt askin for someone to do it...I am 51 years old and dont need someone to do my work, I was mearly asking for tutoring, help, get it, go back and read.I have dont the application, but I dont UNDERstand CODE. I wanted someone to possibly so me how to do this stuff. so far, i have done the app. and the disign of the app. now i changed the names in the property area, (Just the TEXT) area. I cant figure what to put in the CODE area. Is that enough?

When someone obviously posts a homework assignment, I assume it's a 17 yo, in college, who expects to get his homework done and still enter the workforce as a programmer in a few years time. That's the attitude I'm against, which would drive the comments I made.
Basically, if you create the button that you want to do something, in the designer, and then double click on it, it will create the block of code which will be executed when you press the button, and thus also open the code file for you. You can also right click on the file in the designer and choose 'view code' to see where it goes. Obviously, if you're keeping track of anything, you need to set member variables ( variables that are declared inside a class, but outside of all methods, and thus are visible to all the methods, and keep their values between function calls ).
