It is a cashier change return where the user enter the amount owed and the amount paid and when he/she press calculate the program should display the change due as well as the number of Dollars, Quarters, Dimes, Nickels, and pennies returned to the customer. When I run the program sometimes it gives me the right output and others it gives wrong output and it rounds the output. I just want to let you know that I have the option strict on. I will paste the code below

In my program I have the button "calculate" as the accept button, but I want it to switch to reset after it is pushed and go back to calculate.
View 8 RepliesI need to develop a program (of course.) I need it so the user has 3 text boxes, and puts a number into each text box. Then, there be a group with 2 radio buttons.1st Radio Button: Least to Greatest 2nd Radio Button: Greatest to Least When the press calculate, it preforms the correct operation, depending on the radio button click.I just need to know how to make it so it will order from least to greatest. I then can do the rest.
View 1 RepliesUsing 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?
I have an instance of webbrowser control called browser and a command button too on a single form. After clicking the submit button it crashes:
[Code]...
well until a few day ago. I don't know what I have introduced to cause the problem but now, whenever I load the project, VS 2010 (SP1) crahes. If I delete the project's suo file, the project loads (really quickly) and all is well until I exitVS 2010. When I re-run it and try to load the project, it crashes again unless I delete the suo file.The program can be built for x64 and x86. Now, when I reload the project (after deleting the suo file), it comes up in Debug - Any CPU mode. I can change from Debug to Release and from Any CPU to x86 but if I try and change from x86 to x64, VS 2010 crashes.This is not always the case though. If I build the x86 version and then switch to x64, all is well and I can build the x64 version. Obviously, there's something wonky going on.
View 7 RepliesThis is an annoying issue that started less than a week ago and couldn't come at a worse time, as I have a major project deadline to meet. At least once every TEN minutes, the program crashes with the error "Microsoft Visual Studio has stopped working" -- it only occurs when I am writing/editing code while execution is paused (Edit and Continue), which I do all the time since I am stepping through rather complex subroutines line-by-line. I literally have trained myself to save after each line of code I write, delete, or change, so thankfully I never lose much, if anything, when I restart, but it is irritating and time-consuming having to set up everything in the program and get to the place in the code that I was before. I have installed VS 2010 SP1, tried deleting the .suo file, and a few other supposed fixes that I came across online, to no avail.[code]...
View 5 RepliesI create a new Windows Forms Application project in VB.NET without changing any of the settings or labels. Then I click on "Add Data Source" and go through the steps in my programming book. Except that Visual Studio is crashing with a message stating that VB encountered a problem...checking for causes...restarting VB.
Sometimes I get to click the "Debug and Run" button before this happens; other times, it occurs before I move all the labels in form from the data source; and still other times, it happens when I click the "Stop Debugging" button.
I have tried removing VB and reinstalling it, but this still is not helping. (If it matters, I'm getting my copy of VB from [URL]
How can I stop Visual Studio from crashing whenever I try to load or work with a Data Source?
This is going to be a strange issue and I don't expect an answer,.I'm using Ghost32.exe to image HDDs within a Windows PE environment. With the release of WinPE 4.0, we can now use the 4.0 .NET framework. So in order to capture any errors that Ghost reports, I'm redirecting the standard error stream so I can review it later.
But, when I implement those two lines of code (highlighted below), the application crashes.I've implemented error logging with the UnhandledException event of the application, but it never fires during this error. All other errors fire, but this one does not.So I ran it in normal Windows and I receive the following error:Quote:The system cannot find the file specified
But when I comment out those lines, it opens just fine. So I'm a little confused.

I have a few questions:
1. how do I make a button press a certain button in another application? (i.e - for example it goes to application "iexplorer" and press insert, home, a, b, or other button in the keyboard)
2. How do I make a virtual keyboard (for example a button opens form 2 or 3 and when you click on a button in the keyboard it goes to a certain text box in form 1)?
- I'm working on a windows forms application (.NET 4.0). - My form contains a 'Fast Line' chart using the Microsoft chart control included in VS2010. - The chart gets filled with about 20,000 datapoints. - My application then starts receiving market data from a server via DDE (Dynamic Data Exchange) in real-time and adds it the chart.
Note: I have no control over the server and so I have to deal with DDE only even though it's an outdated technology. VS doesn't support DDE anymore and so I use the Ndde library which works like a charm.
Private Sub StartDDE()
'first we connect to the DDE server:
Dim client As DdeClient = New DdeClient("ServerApplication", "Bid")

View 9 RepliesBasically, I have developed one form which is generic and display different views. On that form I have used Close button. Alphabet E is short-cut for closing the form (i.e. mnemonic functionality).During execution of the form, when I press "E" on that form, my form closes automatically. As per my understanding mnemonic works with Alt control only. I am not sure if I am missing any properties that should be set so that this problem is resolved.
View 1 RepliesI have recorded this macro that attaches to a process (nunit.exe) for me. Now I'd like to press a button (named "Run") on the window of the process I am attaching to, but how? I have recorded this macro:
Sub DebugNUnit()
DTE.ExecuteCommand("Tools.ExternalCommand6")
'need a short delay for nunit process to appear in process list:
Threading.Thread.Sleep(200)
[Code]...
I am using nunit 2.5.7 and for attaching and debugging to work you need to attach to the nunit agent and press run on the nunit gui, for more recent versions of nunit you can attach to the nunit gui.the above script enables nunit debugging from the Visual Studio IDE with just visual Studio and the nunit binaries. all you need to do is set up nunit as an external tool (with the current project as a parameter), create a custom toolbar, and add a button to that toolbar that uses the above script. this will start nunit, attach to it, start running the tests, and break at your breakpoint.
one more thing: in the nunit gui disable "Save Visual state of each Project" in Tools -> Settings -> Tree Display or the nunit gui will remember the last run test, which is a pain if that's not the one you wanted to debug.
I had a few small programs that I bought from the internet and so I was building a program that will have all those program in one cd. I got that far that the program is almost done and it opens every program up with a press of a button. Now instaed of writing every product key down on the sheet or have VB open up a text file with the keys on it is there a way I can add the product key to the install with just by the press of a button?
