I am writing a calculator app in VB Express 2008. I'm trying to get the app to accept numeric and operator input while ignoring all the alpha input. In other words taking input from the numeric keypad and the top of the keyboard and ignoring all the letters.
Here's the block of code I have so far:
Private Sub TextBox1_KeyDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown If (e.KeyCode >= Keys.D0 OrElse e.KeyCode >= Keys.NumPad0) And (e.KeyCode <= Keys.D9 OrElse e.KeyCode <= Keys.NumPad9) Then Select Case e.KeyCode

This function doesn't work if I change the input argument 'pdu' from a string to an int.Would someone please help me figure out what to do here so that the checksum does not add the ascii value of the int argument but rather the actual integer value?I took out a few lines of the actual function but it adds the input argument to a packet sent out via TCP protocol.This function shows the integer value just fine in the string that gets encoded as a byte array. the checksum is wrong.!
''Public Function buildpacket(pdu As Integer) is what I want. Public Function buildpacket(pdu As String) Dim packet As String

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:

I am new to this forum and I would like some help from my respected seniors.I am trying to develop a ASP.Net Web Application using C# or VB. First of all prefer me whether C# would be easy or VB for the following scenario:Below are the requirements:
1. For All Users:
Text-chat feature will allow users to chat with the available online users.
2. For Registered User:Allow users to create new folders and sub-folders, to store (upload) files.Allow users to perform move/copy/delete operations on folders and files. The percentage of storage capacity remaining and used should be displayed on the top. Automatic versioning system will record the version/revision information when a file is replaced/overwritten Team management feature will allow users to work in teams (by inviting other existing registered users). The activities of the team include access to the password protected area for the team, uploading files, commenting on the uploaded files (discussion), polls, automatic and manual reminders to the team members.
3. For Administrator:
Approve/Reject new team requests; update/delete existing teams.View all the files and folders uploaded on the server.Allow to perform delete operation on any existing file/folder existing on the server.Delete account for any registered user.Define and Edit storage capacity and other limits such as Maximum file size allowed for uploading.
Queries:
1) As, every user will have his/her own PERSONAL profile page then how will the system redirect the user to his/her PERSONAL profile page after hitting Login?
2) How this chatting feature can be developed?
3) How this storage capacity would be assigned overall?
4) How Administrator will manage all this?
I am totally confused.I have developed SRS as well. but in coding I am totally stuck as I am not so good in coding. I thought Visual Studio 2010 would help me effectively in this case, and I am trying but couldn't find any way for this to be done.

I am very keen to build a simple application to convert AVI to jpg in order to learm a little about video processing. I know free applications that do this already exist. But, I'd still like to develop an application to help me learn more about avi's and to hone my programming skills a bit with a real project.I'm familiar with VB, so that's not a problem. I just don't know how to process an avi file nor how I would programmatically extract the frames from that file.Where should I start? What is required to extract frames out of the avi to individual jpgs?

I would like to do the application that accept the reading from Barcode scanner. What barcode scanner I should use? And, vb.net can support on that and work well?
I would like to develop an application that involves a lot of tables and maths, and then displaying the results. I can visualize how this would work in SQL, as far as creating the stored procedures and tables required, however the front facing application would be a completely new experience to me.I would probably be sharing the built application with friends, but completely as a no profit tool. I assume that the developer edition of dot net is a suitable option? My main query is, is dot net really the best way to develop this tool? I have a strong feeling that I will not be able to use SQL as this would require a server to be run, and this is not practical. Can the tables be implemented into a DLL or similar to be used by the application for example?
I want to develop an app which won't allow the user to open or jump to another application while it is open. It should be in Visual Basic. For example, if my application is open (running) and the user tries to open any other windows application like "media player" then it shouldn't open. The app should not even allow "task manager" to run. The application should completely block the windows environment while it is running.
I need a little guidance here. What I am needing to do is develop an application which sorts text files, approximately 10 at a time.It would look something like this. (Using VBA 2008)The code I am having trouble with, is I want to be able to "load" 10 of these txt reports.I want the Sort button to trigger the application to run through each text file looking for specific keywords.
And finally, when all is said and done, I want it to export a new text file with the keywords listed that it found.I am just breaking into this and am super excited with how much I have learned so far!

About 5 years ago I wrote this program in Excellusing VBA to compute commissions, income and expenses for the real estate agents in my wife's business.The company is made up of about 50 agents. Part of the program includes a combobox on a main form when a name was selected it also selected, the agent id, and the split the agent was on. It would calculate the split expense that my wife got by multiplying the split percentage from the combobox times the total commission.The main form also contained various other comboboxes, list boxes, and text boxes to gather such info as property address, selling price, titles company, transaction credit,income,Once all the info was complete my wife was asked if she wanted to save the transaction. If the answer was yes, the info was transferred to the permanate database, a commision report for the agent and my wife was printed out, and the temporary database was cleared.
I have a VB.NET application that takes command-line arguments. It works fine when debugging provided I turn off Visual Studio's ClickOnce security setting.The problem occurs when I try to install the application on a computer via ClickOnce and try to run it with arguments. I get a crash when that happens (oh noes!).
There is a workaround for this issue: move the files from the latest version's publish folder to a computer's C: drive and remove the ".deploy" from the .exe. Run the application from the C: drive and it will handle arguments just fine.
