Creating An IM Type Program?
Mar 23, 2012
Alright I am just starting out with Visual Basic and I am trying to figure out how I would go about doing this. I have the general idea of how I want it to be done but I am not sure of what code I need to use. What I want to do is be able to type in Text box 1 and copy whatever I type into Text box 2. But I also want to be able to send it to anyone else with the program that are listening for a connection. I also want to be able to show the IP address in Text box 3 that the computer is using at the time.
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChanged
[code].....

I want to create a generic list - but I want to specify the type at runtime - is there a way I can do this? using reflection perhaps?Something like this...
Public Shared Sub create(ByVal t As Type)
Dim myList As New Generic.List(Of t)
End Sub

I'd like to create a list of an anonymous type, for example:
Dim dsResource = New With {.Name = dsResourcesEnd(index).Last_Name & ", " & dsResourcesEnd(index).First_Name _
, .StartDate = dsResourcesStart(index).Day _
, .EndDate = dsResourcesEnd(index).Day}
I have created that anonymous type. Now I'd like to add it to a list of that type. How do I declare a list of that type?

I have been working on a very advanced feature that will allow programmers to right object that spit out other objects. Code that writes code. However, I have run into a problem. I use a file type that specifies to the coding parser how to create the object that is going to write the objects. Example, the Programmer writes a "NTF" file which contains code switches and variables that the Computer will parse and create a "Template Object" that the programmer can include in his project and call to generate the code objects. I'll right a object that creates an ASPX page for each table in my database, and I'll then call that object against my database. It's pretty straight forward. This "NTF" file has special parser commands, and uses VB.NET to manipulate the output based on the variables that come into the object. The problem is I would like to have an editor just as advanced as Visual Studio to recognizes the custom parser commands and the VB.net code. At the very least, something that formats the "NTF" file and integrates into Visual Studio.url...

First I put it inside a Module and it works just fine. However when I created a Class and put it inside it, it showed up some errors. (they are in the code's comments)
Public Class MyImageClass
'function to merge 2 images into one
Public Function Merge(ByVal img1 As Image, ByVal img2 As Image) As Image 'Type 'Image' is not defined
Dim bmp As New Bitmap(Math.Max(img1.Width, img2.Width), img1.Height + img2.Height) 'Type 'Bitmap' is not defined
[Code] .....
I tried importing the System.Drawing namespace to this class which didn't change anything either. I've never really touched the OOP side of VB.NET before, this is my first attempt creating a class.

Anyway, I'm a teacher and am writing a program that simply shows kids a word on a flashcard. There are 2 buttons, 1 to read the word and 1 to go to a new work. There are going to be 300 words. Really I'm just testing it right here. What I want to know is should I be inputting all the words right into the code like I did with "hi" and "not 1" (Don't ask. those are just the 2 random words I picked to test this out with). OR is there a better way (maybe somehow to type all the words on a text file and have the program randomly pull one of them (I don't know how to do this).
Here is the code so far:
Public Class Form1
Dim word
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

I have a vb.net app that I create an excel file with from sql data. It creates it fine but for cells that have a social security number, it makes that cell numeric and removes the leading zeros. Does anyone know how to force this cell as a string when adding it to the worksheet? Is there a property or method I can call to do this in my vb app?

I am creating a gridview and need to gather the data from various functions that return a type of IEnumerable. I've created gridviews using a dataset as a datasource, but how does one use multiple data sources(of IEnumerable) to populate one gridview? Like how do you combine all that into one dataset?

Fist off, I am new at this and only learning it for a class. We have a program to create using Visual Studio 2008. The teacher doesn't give us much to go by so I really have no idea where to even start so any code will be a great help. Here is what i have to create:Your project will allow the user to enter a stock transaction and determine the stockbroker's commission. Each transaction includes the following data: the stock name, pricer per share, number of shares involved, and the stock broker's name. Assume price per share = P. The stockbroker's commission is computed in the following manner: If the P (price per share) is less than or equal to $50, the commission rate is $0.19 per share, if P is greater than $50, the commission rate is $0.26 per share.

I would like to click next to go to another image in a picturebox but I only have one picture box setup to have the new letter displayed in it. I have 26 images to display and need to know how to setup a loop to go through each image? It seems simple but I cannot figure out how to get to the third image, it only goes to the second image and stops. I also need to know how to setup the back button to display the prior image in a picture box.

I'm trying to creat a program that tracks the sales of five products all with different monetary values. I'm trying to display the total number of each product sold, a combined total of products sold, and the total sales value. So far I'm only outputing the value of one of each product, I think there is a problem with the loop somehow. [code]

I'm wondering how I would go about creating a program that once installed was a windows toolbar. What I'm trying to do is similar to the clipboard, but I want to customize it to my own style. I work in a data entry job and many of the bills we enter have similar information that I'd like to be able to enter without repeated typing. I'd like the toolbar to be docked to the top of the screen, and have several buttons on it. Clicking a button, while having a focus in my data entry program, would paste the button's text (or the full text of what the button caption represented) into the selected field. Alternately, if focus between multiple applications is too difficult to try, then clicking the button would highlight the text and copy it to the windows clipboard, so I could then click back into my data entry program and hit ctrl-v. I dont need help on the program itself...just on how to make it as a windows toolbar, if possible.
