I m trying to use multi code file that contains events, functions etc...I have a form that named Form1.vb, code file Tab1Codes.vb and a class ClassUsers.vb.Form1 is containing a function like:
Public Sub Tab1ShowHideFunction()
'some codes....
End Sub
Basically I want to create a little program with 5 or so text fields where I enter the specific names of movies. Upon pressing a "go" button it then does a google search(with certain criteria) for all textfield entries on the website [URL} and then download the files, if possible without opening a browser.
Search criteria:
-only video formats(.avi .mov etc)
-download url contains the "_de" tag (to insure german trailers)
That way it should hopefully find the right trailer and download it. If possible have it use progress bars.
How much work do you think this is? Or is it even possible? From a logical standpoint I don't think it's too much work... I am using Microsoft Visual Studio 2008 Express Edition. My project currently is just full of test code but I will post it anyway:
Code:
Public Class Mainwindow
Private Sub Mainwindow_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

I have a question about creating a multi-language application and the use of resource files. I will explain what I have done and what I would like the final product to be like.I am doing this in VB.Net and using Visual Studio 2008 After creating a new project, I added a resource file to the project (Add -> New Item, Selected Resource File, named it Resource1.resx).
I then double clicked the resource file and was able to add some names and values. For example,
Name - lblFirstName, value - John
Name - lblLastName, value - Smith
On my form, I have 2 labels: FirstName, and LastName
In Code, I added
FirstName.Text = My.Resources.Resource1.lblFirstName
LastName.Text = My.Resources.Resource1.lblLastName
If I run this code, it works fine. John and Smith are displayed on the labels. Now for my question. Say instead of first and last name the labels (buttons, menu items, etc.) were actually words that would be different in different languages. What I would like is to have something like
EnglishText.resx
SpanishText.resx
GermanText.resx
Each resource file would contain the same names, just different values. Depending on what language was selected, decided by the user (from a menu), how can I get the matching resource file to be used.
Basically what I want would be FirstName.Text = My.Resources.<Language Specific Resource File>.lblFirstName
Is something like this possible? Is this an acceptable approach? Is there a better way of doing this? I try to check often to see if there are follow up questions or if more information needs to be provided.
m currently learning vb.net. I have a program that replaces text in files but right now it only does it with one single file. I wan

well i am populating a listview with some entries from an explorer tree, but i want to create a multi-column listview in which column 1 holds
the name of files added by me and column 2 hold locations of the corresponding file.
for example, i would like to find the key word "1234567" from the folder which is consist of many of the text files, what are the command i would need to apply into my script ?The folder consists of few files namely as example:
abc_120811.txt
abc_130811.txt
abc_140811.txt

When the button is pressed, it all works and the following files are created: yahoo.dll and yahoo.pdb My question is this: What is the code to load the already compiled yahoo files to execute the code again, without having to recompile the code?
I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.
View 5 RepliesHow can i store unlimited multi-row strings without the need of extra files?Example: the user enter a multi-row string into a textbox and clicks save. Then the program should save that somewhere. And then the user enters another string and clicks save. And then there is a combobox where it can choose between those 2 strings to load.Can i save them in some sort of collection like My.Settings.Collection? Where each text also has a header.

I've created an application, And now need to add the chat feature. It just needs to be basic, But im un sure on how to code one since i am still a beginner at Visual Basic. I know there is a way via TCP Listener using Net.Sockets, But im stuck there. I am totally out of my mind when i think ill know how to code. But here is how the chat will work[code]...
Server side, Is just to host it. I will host it on a windows vps with ports opened, and Anyone who downloads the program can connect to the chat. The username or Nickname of the user will come from 'My.Settings.username'. At this point I am willing to pay someone to code this project.

I am creating an IDE for a game script with similar functionality as the Visual Studio IDE (at least, some of it). The game script consist of code that looks visually a bit like C code. It uses braces to define the start and end of a 'class' and uses nested braces to define the start and end of an 'event' in a class.
What I want finally is to have two Comboboxes above the text editor, one that lists each Class and the other listing each Event. The comboboxes should also show the Class and Event that the caret is currently in, just like in Visual Studio.I have attached an example of such a script (you can open it with Notepad).However, here is a short example where you can also see how I "defined" classes and events:
class1
{
event1
{
[code]....
As you can see, the classes are the 'names' of each block of code, defined by matching braces { }. The events are the names of each nested block of code, also defined by matching braces { } but inside a class. There is only one level of nesting.As you can also see, the layout can follow the standard C-style layout, or a slightly different layout (using the opening brace on the same line as the class/event name), or even a completely chaotic mess. As long as the braces match correctly, the code is valid.So in short, the large blocks are classes, while the nested blocks are events.
What I want to do, is parse an entire script, and store all the Classes (and eventually, also all the Events, but let's forget about them for now). I want to store the Class name, start position (defined as the start index of the name), end position (defined as the index of the closing brace) and the full text (defined as the text between start and end position, so including the name).
vb.net
Public Class clsClass
Private _Name As String
[code]....
The code works basically by finding every first opening brace (the opening brace of each CLASS, not event), and then loops through the class (using a brace counter to keep track of the nested braces) until it found the last closing brace. It then stores the name, start, end and fulltext in a new clsClass and adds it to the list to return.
Multi-Threading. I have got a simple bit of code that will need to be repeated but with a chance of it overlapping the only complex bit is there will be a varible that will be different each time. so I was wondering if I put it in another Thread and store the varible within the thread code would that achieve what I am looking for? To make it slightly easyier once the thread is started and pulled the Varible in there will be no cross talking between the thread and main app thread (ie no progress reports, no aborts/suspends etc) Nothing will be feeding back on thread completion either, when it ends it ends.
This is what I have so far:

View 2 RepliesI have this code to set array values and store them in a variable,
Dim productName As String()
Dim productPrice As String()
Dim productCategory As String()
[CODE]...
How do you get the variable values to output like this?
<input type="text" value="Chang Beverages $19.00" id="Chang" /><br />
<input type="text" value="Ipoh Coffee Beverages $46.00" id="Ipoh Coffee" /><br />
<input type="text" value="Gula Malacca Condiments $19.45" id="Gula Malacca" /><br />
What do I want to achieve: I want to perform some time consuming operations from my MDI winforms application (C# - .NET). An MDI child form may create the thread with the operation, which may take long time (from 0.1 seconds, to even half hour) to complete. In the meantime I want the UI to respond to user actions, including manipulation of data in some other MDI child form. When the operation completes, the thread should notify the MDI child that the calculations are done,so that the MDI child can perform the post-processing.Should I use explicit threading (i.e., create explicit threads), thread pools? Or simply just propose your solution. Should I create foreground or background threads?And how does the thread communicates with the GUI, according the solution you propose?
View 7 RepliesWondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

View 10 RepliesI'm adding multi-threading facilities for the first time. I have a function that is wrapped to be run in a separated thread. This function retrieves data (text) from a combobox and it works for sure without multi-threading.
When I call it as multi-threaded, I get the following error when I try to retrieve the data from the cmobobox: Cross-thread operation not valid: Control 'cmb1stBL' accessed from a thread other than the thread it was created on.
It looks like a restriction of thread-safety... I assume that the child thread cannot read from his parent, to make sure that he doesn't change his parent data. So how can I read the data from the combobox? Should I read the comoboxbox data before calling the child thread?

I have 19 .CSV files that hold engineering data in single and multiple Arrays.I would like to loop through the Directory that contains the files and open each file, fill the array and close the file and continue to the next in Alphabetical order.
This code tells me how many files I have now and will update if I add more.
Dim FolderPath As String = IO.Path.Combine(Application.StartupPath, "DATACSV Files")
Dim TestFolder As New IO.DirectoryInfo(FolderPath)
Dim FileCount As Integer = TestFolder.GetFiles().Count
FileCount give me my number of files but not sure how to continue. I have the code to open and read the file but not how to keep changing the file name for each new file name base on the number of files that exist.
Actually, I have code for upload files, but I get error, when I try it.[code]...
