Write A Short Program - Structure The Code?
Feb 2, 2009

I'm pity sure this is majority the wrong way to structure it as at crashes with the IF/ELSE field going up to around 50000, but it does work (if a little sluggishly) when set to 5000.[code].....

Some time ago, I did some F# programming, the following code is used to serialize/deserialize float32 array:#light
However, nowadays, I have to do some programming in VB.NET to serialize/deserialize float32 array again. As F# programming is not suitable for GUI, but GUI is necessary for my current programming.I want to know how I can rewrite the above code in VB.NET.For example, I have a float32 array, (I dont know what data type in VB.NET is equivalent to float32 array in F#) of (1.0, 2.0, 3.0); I want to serialize it using DataContractSerializer, then read it back so I can still get the same float32 array.

I'm writing a simple program to retrieve data via the Serial Port. I have a piece of hardware that returns its 14 byte status every time vbCr is written to it. The program works fine except after a few hundred requests the program begins to hang, off and on. Some times for a second some times for longer. I need to update every 25 milliseconds so the hanging sets in quickly. This faster the interval the quicker the problem sets in but no mater how long the interval the problem eventually starts.[code]...

I am once again struggling with my weekly project. I am assigned to write a program that converts a predetermined english sentence to both french and german. The code is to contain an Array and a structure. Also we have not covered retrieving array data from a TXT file, so we are to hard code in the array data. I coded the structure and the array, I added the array data, but am confused how to access the data. The examples I have found all deal with retrieving data from a TXT file. Can someone give me a nudge in the right direction.[code]....

i am asking that can i use c# language to implement "actions" fired on "click side events" such as mouse over the reason for this stupid question is that i remember some syntax of registering functions for particular events of formview, which are call when the event occurs (yes there ispostback involved" is something like the above possible for client side events using c# or even vb.net
protected void Page_Load(object sender, EventArgs e)
{
Label3.Text = "this is label three";

I have a database structure filled with data that I'm trying to write out to an XML file. Here's a taste of the way the VB code is structured:[code]I can't see or report any progress, because the processing is all tied to one giant LINQ query. Even if I can't make it any faster, I'd like to know how much longer I have to wait. My first version of this code had For loops instead of queries, so I could display progress, but it took a loot longer.Obviously I'd like to speed this up considerably. It seems like there should be a simpler way to convert the data to an XML file, especially since the database structure was created from the XSD in the first place.

For my application, I want to have one form ("Action Form") that (1) remains visible, (2) reports progress in a scrolling text box and (3) receives user input via clicks to its command buttons and menus.While the program runs, I need to show some results in different forms in two other windows (let's call them "Graphic Form" and "Accounting Form"), updating these as we run. You might call these Read-Only windows.
That's it. Can't be all that difficult, right? I did it in VB6 with no problems.However, in my .NET attempts, once I update information on either of the other forms, my Action Form loses focus and I can't get it back. It's there and it keeps updating, but its menus and buttons don't respond any more.
Is it possible to manage three (or more) Forms in this fashion. Maybe the other windows should be Frames or something instead of Forms, but I can't see how to do that.(It may be because I'm using "Sleep" to slow the updates to readability on the other forms. Maybe I should be using a timer.)
EDIT:It seems to work so long as I take care to update the Action Form last of all, after the others, so maybe this is a "Never Mind."However, if anyone has any ideas on how best to implement Read Only Windows for auxiliary displays, I'd like to hear them
