Hi Gregory. Well, you could use MenuItem.Text for the menu item caption, or you could use MenuItem.MenuID for the item's Windows identifier...

regarding vb.net console apps...
i was wondering if there was a way to determine when any key was pressed? so it can be used for instances where a 'press any key to continue' type of thing is necessary, or where a one character answer is required.

Thx.

Check into Console.Read() or Console.ReadLine().

thanks
iv already worked with .read() and .readline().

.readline() gets input from the console. the user must press enter key to end the input.
.read() is just like .readline but it doesnt read the full line of text the user entered, if it was even a full line at all.

in both cases. the user must press the -enter- key. is there away to do it without having to press enter?

OK. The Console class doesn't support the type of input that you want, ... yet.

You'd have to look at the Win32 API to get what you want. Specifically, the GetConsole, GetStdHandle, GetConsoleMode, SetConsoleMode, FlushConsoleInputBuffer, and ReadConsoleInput functions. You'd have to write your own PressAnyKey function that, when entered into, gets the handle to the current console window, get the handle to the StdIn stream, saves the current console input mode on the stream, setups up a new mode that disables LINE INPUT, then use FluchConsoleInputBuffer to clear out any remaining keystrokes. Put up your 'Press any key to continue' prompt, then use ReadConsoleInput to get the next character in the input stream. When all that is done, then you restore the console input mode and call FlushConsoleInputBuffer to clear any remain keystrokes out.

Hopefully(!), this functionality will be in .NET 2.0.

Most of it from memory, but a little research on MSDN for the specifics...

Who knows...if I get the time, I might make a class out of it and write up a CodeProject article.

I want to specified my datalist's style on run-time by program,not on design by html.Such as,the style may be title+author or column+title,because i want to change the style by my option ,so i have to bind data when run-time.
Following is my code,i just want to test it, but it doesn't work,even doesn't display article list.
dim ams as new AMSystem()
myList.DataSource=convertdatareadertodataset(ams.GetArticles(params))
myList.DataKeyField = "ID"
myList.DataMember = "Title"
myList.DataBind()
Would you do me a favor?
Looking forward to your reply.;)

accessing variables

simple question.. using vb.net for a small vb windows app:
where is the best place to declare an object variable?

i have a custom structure which i have delcared a variable array with..
each method in the program must be able to access this variable (its a simple 1 form, module, class program)

thanx in advance.

EDIT:
i am currently using a module level variable

If your variable is going to be accessed by many of the methods in your class, make it a global variable by putting it just after your class statement.

Public Class myForm
    Inherits System.Windows.Forms.Form
 
    ' Global Variables go here
    Private myGlobal as Integer
 
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
    .
    .
    .

ok thats how i am doing it. i was just wondering if this was the most efficient way of attacking this.
also, i used 'dim' rather than 'private', in classes they are the same thing, no? are they always the same thing?

thanks Dave

Seeking a "Deck of Cards" PDF/TIFF Manipulation & Separation Tool...

12-Mar-04 7:42

They do the same thing, such that Dim is actually optional. But, the variable visibility changes depending on wether it is declared with Public, Private, Friend, Protected, Protected Friend, Static, Shared, ... Look up 'Dim' in the Visual Studio help for the explanation as to what all of these do, with examples.

We need a ""PDF/TIFF Multi-Page Manipulation & Separation Tool"" with a
visual user interface for separating one multi-page PDF/TIFF file into
separate files and saving those separate files. Envision a user interface
that treats a multi-page PDF/TIFF like a "Deck of Cards"; the deck can be
split into two or more decks, any one card may be discarded, and the order
of cards within a deck can be changed. Another desired feature is the
ability to copy any one card and reproduce it.

We are seeking to pay to aquire this technology, preferably in VB.NET with the full source code so we can continue to adapt it to our needs. We can pay very well for this - please get in touch.

Although it is an easy task to determine whether or not a tool is running in the Integrated Development Environment or in a compiled executable outside of the IDE, I’m having great difficulty in doing so with a non-tool DLL.

I have created a custom DLL in VB .NET that provides only objects and shared methods… none of which require the creation of a tool style interface. The objects are simply created, used and destroyed by the calling code, as needed.

Is there a way that I can determine whether or not my DLL is being loaded and run by an application from within the IDE (development environment) or is being called from a compiled executable or other process outside of the development environment?

It seems that I ran across an article on how to do this a few months ago, but have been totally unable to locate that article again. I’ve gone back through all of the .NET documentation I have on hand and have not been able to locate that particular article.

I would very much appreciate a bit of sample code from someone who knows how this is done… if it can be done, as I am quickly going blind from all the searching.

Thanks

Not a Valid Win32 Application Error when Launching New Program

Hello,

I just finished a small application from VB.NET and tried to install onto my PCs as a test. The install worked fine on my Win 2000 PC and the program launches fine. However, when launching the application from my Win 98 machine, I am getting the error that the _294823.exe is not a valid Win32 application.

Firstly, I'm not sure why it's being refered to as _294823.exe. My application name is Timer Utility.exe. When installing, I got the error that I didn't have the .NET Framework, of which I've gone and installed after this error and before installing my application.

Your help is greatly appreciated.

Thanks so much!
