I have the same intention as in this question:
Automatically call all functions matching a certain pattern in python
But I needed the solution (if technically possible) in VB.NET. Is that possible in VB.NET ?
I have text like following example
XXZZXXXZXXZXXXXZZZZZZXVVVVVXZVZ
and also I have two patterns like XX and ZZ I want to find longest possible string which include above given two patterns and return starting and finishing index of the array.
I need A free source code for pattern matching(finger print matching) .
View 1 RepliesIs there any way to detect the area under a form window. e.g I want to create a grid and use what's in that grid to match patterns.orIs there any way to take a screenshot of the area under a form?
I have been searching all over for something that will do this and the only thing I managed to find was [URL]..I do not however want it for this application (If I really wanted to cheat at a game I would buy the software). But this is a perfect example of the pattern matching I wish to achieve.Edit: OK scratch that... I have managed to take a csreenshot of the region under a form, now has anyone any experience in pattern matching images?
I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)
I am fiddling with the code here: [URL] I had a couple errors when I copied/pasted it into my project. I dimmed a couple variables, now the squiggle lines are gone, but I'm not sure how to call the functions in the project? Do I use a Lable or a TextBox? How do i make this work?

i wanted to use streamwrite i use System.IO at the top of the code. What do i use if i want to use the E-Mail capabilities of the program?Does it matter what e-mail program u use as to what Process to call?I know that MAPI whould be there somewhere but unsure.
View 4 RepliesI have a Util module in my VB.NET program that has project-wide methods such as logging and property parsing. The general practice where I work seems to be to call these methods directly without prefixing them with Util. When I was new to VB, it took me a while to figure out where these methods/functions were coming from. As I use my own Util methods now, I can't help thinking that it's a lot clearer and more understandable to add Util. before each method call (you know immediately that it's user-defined but not within the current class, and where to find it), and is hardly even longer. What's the general practice when calling procedures/functions of VB modules? Should we prefix them with the module name or not?
View 3 Repliescodes to implement buttons to do the following
1. Pause a process/ action event.
2. Resume the process/ action event.
3. Stop the process/ action event.
4. Speak the time based on the clock.
say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?
View 2 RepliesVisual Studio 2008, Standard Edition VB.NET I have only limited experience using the background worker, and all that I've done with it thus far was fairly straightforward and worked fine.
I am now looking to run a process in a background worker which calls various functions and/or subroutines, but of course it generates an error indicating that it's on the main thread (or something like that - I don't recall exactly, but that was the crux of it).
Im not exactly sure how to word this question, but I will give it my best shot.In a new program I am starting I would like to put all the code from a button_click event into a file (many others as well into different files), kind of like a class file in the sence of it being external.lets say I have a button called btnadd and it has some validation code in it Private Sub btnadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnadd.Click

View 6 RepliesI have implemented webbrowser control in my windows application. I have some functions inthe class file. i want to use those functions from the webpage which is displayed in my windows app through webbrowser control..For example say... I have an standalone windows software. Which has a webbrowser control in the some form. Now i would like to create a webpage that can be displayed in the webbrowser control in win app which has some buttons and textboxes. When i click on button in the webpage it should get the version number of that software. I have some other functions that are in the class file aswell.. but dont no how to call those functions from that webpage when a button is clicked or something like that.
View 4 RepliesI have a midterm project where we must replicate what our teacher has made, it is a convenience store program. I am having trouble calling the functions, he wants us to use these:
PopulateItems => Populate Items listbox based on the category selected
GetItemPrice => Retrieve the price for a given item
GetItemPriceFromPurchases => Retrieve the item price from the purchases list box (optional. You may not need

So far I have the first list box populated when the form loads. However outside of that I do not know where to call the function in order to populate the second list box upon selection of the first.
im wanting to add a new feature but am unable to even get started. I'm in a windows form in visual basic .net and basically, I have a combobox with 3 items in the drop down menu. I would like to make it to where the moment one of the items in the combo box are selected, the program recognizes the change of index and automatically calls to the function of my choice.
View 1 RepliesI was trying to make a program for a teacher that automatically determines random students that he or she can call on.I'm trying to make a program that will allow the user to add student names to a listbox. Then, when a button is pressed the program will output a random name from the list. I keep getting a lot of errors and can't seem to figure out why. Finally, I need an exit button that should close the program. I need to assign access keys, have a proper tab order, and assign default and cancel buttons for the form. Also, if you know how to implement any extra 'bells and whistles' into the program,I've tried making this program but it comes up with either a lot of errors, or it just doesn't want to debug. Was wondering if I could either get some help with the coding or the "how-to" on doing this.

1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.
For example the function: Membership.FindUsersByName()

Sort of like in C where we would have nested structures?
Its a FILE I/O, with robot commands, moves and verifications....
So I would find the line in an excel spreadsheet where it moves, the coordinate, put it into an array.
Take the actual results store them into a two dimensional array...etc, etc....
Another function would eventually compare the results with the moves, and within a tolerance.

Open -209.037
18N694 P321 117461, 50374 100MIL;
from the line i must take P321 and match with my File2 if i find the mathing line like this
12N709 11.3611 4.9474 P321 L6 BOTTOM 100MIL 43-CHISEL X11.3611Y4.9474 1922 0
then i must take the value beside P321 which is L6 and write it in my original file like this
[2 11.63 39.7] X7.705 Y0.735 209.037
Open -209.037
18N694 P321 117461, 50374 100MIL; L6
How we can do this. To get the P321 from my file 1 can i use regex pattern like this P*[0-9]. And how to match the regex pattern with file 2 write the content ?
