1. How similar is the .NET to JVM in executing a program ?
2. How different is it ?
3. Is the .NET Framework available for Linux ?
4. Can I run a VB.NET application written for XP on a Linux machine ?
I'm developing a program that is similar to ATM but I can not keep track of various clients so that each may have their account
View 7 RepliesI've been using the 2006 SerialCommChat program to do my programming functions.This only has CommPort availability and I'm needing both Commport and what I guess they call a Virtual Port known as the USB Ports.
View 5 RepliesI've looked around and I haven't found anything that fits my needs.I wish for the program to be able to intercept the Win32 (?) messages that are being sent to my own application, which is written in Visual Basic.As a side note, is "intercept the Win32 messages" the correct phrasing?Either way, an elaboration won't hurt; I wish for the spy tool to intercept the same messages that I would programmatically intercept with WndProc, i.e: the SendMessages and PostMessages.
I wish to make it clear that I am not seeking a program that intercepts the .NET framework events.

View 1 RepliesI have a contact manager program that I'd like to design for multiple network marketing companies. My desired structure would include a core program which covers basic contact management functions. After that one could purchase a module for their specific network marketing company. This module would contain a variety of controls that the original program would need to be able to manipulate. Here is an example of what it would have to have:A group box containing buttons that link to a genealogy view, and the option to import one's donwnline from the back office provided by a company.A panel which is displayed on the contact page allowing the user to input business information or which will be filled by importing a downline from the back office: ie business ID, qualification level, sponsor information etc.a panel displayed when one searches for contacts on the contact list page which allows the user to sort based on information such as when they joined, what their business id is and so forth.a panel which is displayed in a personal business overview page which presents to an individual how many people in their downline are at each qualification level and develop a mailing list for individuals of a certain qualification level.
I have the code developed to perform all these functions, I just wanted to give you an example of what needed to be done. I'm thinking that what I'm trying to create is a library that one can download and the program will recognize, but I'm not really sure where to go. What I'm really trying to do is figure out what kind of file I can make that will contain all this code and the GUI information that the program will recognize.
I am working on a project, in which I have to run a MATLAB program in VB.NET In the project there is a VB.NET GUI, which contains a browse button. The user has to click on the browse button and select an image for processing. The user then has to click on the Process button for processing the image. After clicking the process button the image selected by the user has to go as input to the MATLAB program.
Q1) I want to know how to give the image selected by the browse button of VB.NET, as input to the MATLAB program for processing?Also while the image is being processed in MATLAB, a message such as "The image is being processed" must be displayed on the VB.NET GUI.
Q2) how to display the message "The image is being processed" on the VB.NET GUI, while the image is being processed in MATLAB?After the image has been processed in MATLAB, the image must be displayed on the VB.NET GUI.
Q3)how to display the image from MATLAB program in VB.NET GUI?

View 1 RepliesI have my program set up to download a web page with a webclient. Normally, I could just use .Substring, but there are about 25 things I need to pluck out of this page, and .Substring, or at least the way I have it set up, takes the first occurrence. The good news is, they are all URLs; they are all similar too.
Each URL is as follows: [URL]
Now, of course, this URL is just made up, but each URL starts with [URL] and ends with 'video'.
How can I hook this up so that it scans the entire page (contained in a string, read from a StreamReader connected to a WebClient), finds each URL, and then adds it to a listview?

I have created a simple application where I fetch questions from an Access database and store the answers to another Access database. I am not sure how many questions client would like to ask, so I can't hardcode that number.
So, column names for answers table (besides user information like first, last name and so on) will be a1, a2, a3 ... aN.
And finally the problem!
For testing purposes I have hardcoded saving first 3 answers like this:
newEntry.a1 = answers(0)
newEntry.a2 = answers(1)
newEntry.a3 = answers(2)
Now I would like to iterate through all properties based on count of "a-type" properties:
'aCount is number of "a-type" properties
For i = 0 To aCount - 1
Dim property As String
property = "a" & (i + 1)
newEntry.property = answers(i)
Next
Of course, above code does not work, it is just a pseudo-code idea that "should" to the same as my hardcoded example.
Is it possible to iterate through predefined properties of newEntry object in that manner?

View 9 RepliesI have some difficulties concerning threading [code]
Code:
1- Dim str As String
2- Dim x As New myClass
3- str = x.doSomething()
4- x.closeSomething()
I've included line numbers so I can just refer the lines by their numbers. My problem is, when the program executes, line 4 seems to be executed earlier than I want it to. It gets executed while ThreadX is still running in line 3. How can I force the program to wait until ThreadX has finished executing, before it executes line 4?

I have a button and various other controls that when clicked, calls as sub. However if the user clicks the button or any of the other controls multiple times, the sub appears to 'stack up'. For example, if I click the button 10 times, and then some of the menu items that trigger it 20 times, the sub would 'stack up' and execute 30 times total. How can I have the sub cancel calls to itself if its called again? I basically only want the latest call to it to count.

I was once using a program that was under beta, so the creator added a nifty feature. You could enter any vb.net code into a textbox, and when you pressed the button next to it, that code was executed. For example, you could type MsgBox("hello") into the textbox, click the button, and it would run that code as if you actually put it in the source code and ran it. I've googled so many different phrases trying to find out how to do this, but I can't find anything. Anyone have any ideas or resources I can look at?
