Reiterates The Inputs And Gives The Resulting Tip?
Feb 16, 2011
I am stuck on a homework problem and was wondering if anyone could help out a beginner.The question reads:Calculate the amount of a server's tip given the amount of th bill and percentage obtained via input dialog boxes. The output should complete sentences that reiterates the inputs and gives the resulting tip.
here is what I have so far:
[Code]...
It works fine if I input the tip percentage as a decimal, but I need to be able to input a whole number for the percentage, and in turn, output the correct decimal. I'm sure this is a pretty easy fix,

As I wanted to benefit from new multicore threading improvements from .Net Framework 4, I recompiled all of my solution projects from 3.5 to 4.Everything compiled Ok. But what was my surprise to see that my application runs much slower when compiled in .Net 4 compared to 3.5. I was not expecting that at all. It is a scientific processing App, so computing time is what it's all about. I have no clue where to start from, and for the time being, and I prefer to think that I have missed something during the migration process, that is fixable, rather than the App is "per se" running slower in .4 (can't see any logical reason for that...)

I was working on an app that calls a batch file to do some simple tasks and found out this machine has some issues when trying to run them. really weird! so i did some testing and here are my resultsthis is a little strange to me and i can't think of why this is happening... let's say i have a simple bat file called test.bat these are the contents
@echo off
echo testing...
pause
When i go to run this bat, this is the output: C:>â– @ 'â– @' is not recognized as an internal or external command, operable program or batch file. It seems every bat i make on this machine is being preempted by the block character which renders bat files useless...

I'm exporting a datagridview to excel. The first column is a Date (not DateTime) which appears like '2/15/2011'. After exporting the datagridview to excel it appears in excel as '2/15/2011 0:00', furthermore the first 68 rows in excel appear as '6/14/1898 12:00:00 AM'. Where is the time coming from? The column type in the database is date. I've attempted to edit the cell style of the datagridview column to date. I've attempted to figure out how to pre-program the formatting in excel, but it's not working either.

I have a folder with a whole lot of music in it (*.mp3 files.). Now on my form I can play these songs in playlists, and other extra's. But now what I want to finish it, is to create a search function. Here is a picture of my Form. And what I want to add is a Listbox, TextBox and a button.
When I type: "Eye of the Tiger" in the Textbox and click the Button, All *.mp3 files in my folder, and the subfolders, with "Eye of the Tiger" in it, are added to the Listbox (The full name, like: "Survivor - Eye of the Tiger") will show at the Listbox. How can I do this, in an easy way, if possible.

I want to combine multiple lists of items into a single list, retaining the overall order requirements. i.e.:
1: A C E
2: D E
3: B A D
result: B A C D E
above, starting with list 1, we have ACE, we then know that D must come before E, and from list 3, we know that B must come before A, and D must come after B and A.If there are conflicting orderings, the first ordering should be used. i.e.
1: A C E
2: B D E
3: F D B
result: A C F B D E 3 conflicts with 2 (B D vs D B), therefore requirements for 2 will be used.
If ordering requirements mean an item must come before or after another, it doesn't matter if it comes immediately before or after, or at the start or end of the list, as long as overall ordering is maintained.
This is being developed using VB.Net, so a LINQy solution (or any .Net solution) would be nice - otherwise pointers for an approach would be good.
Edit: Edited to make example 2 make sense (a last minute change had made it invalid)

I'm working on a program dealing with jagged arrays.Code is below.The FindPath() function works perfectly.It essentially randomly chooses an action from 3 possible choices.The goal of this function is to make it to position (3,3) from (0,0).Sometimes it makes it, sometimes it doesn't.It gives up after 2000 moves.
The PushButton() function is where I have the problem.I want to run the FindPath() function 2000 times, and return the resulting list of moves into intLists()(), my jagged array.I want to use
intRuns = 0
For intRuns = 0 To intLists.GetUpperBound(0)
lstMoveList.Items.Add(intLists(intRuns).GetUpperBound(0)) 'here is where I get the problem.
this section of code to dump the number of attempts it took into a listbox on the main window.I do this at the bottom of the FindPath() function, but that is for testing purposes only.I eventually want to take the successful attempts and manipulate those, so eventually I get the minimum possible number of movements to get from the starting point of (0,0) to the ending point of (3,3).
Function PushButton()
Dim intRuns As Integer
Dim intLists(2000)() As Integer[code]...............

so i have a user form, and i want to uncheck certain checkboxes if some conditions are met, etc. the problem is, i also have instructions that are supposed to take place when the box is clicked, BUT these are done when the actual value is changed, even if no click takes place. how can i get around this? i tried to have some boolean barriers but because of the complexity of my code, theres no logical way of doing it. is there some property i can use to just change the value and not register a click?

I am developing an FTP program which: Watches a folder. If a new file is dropped there then upload it. Tells user if uploading and when complete. All the above works, however I wan to add the items to a listbox that are being uploaded. So if I dropped 3 items there it would look like :
Upload Listbox:
cake.jpg
myExcelFile.xls
woot.docxAnd as each one is done, or new files are added it removes them or adds them.
I tried using que, but with no luck as the program just hangs whilst it uploads. So I had a search and looked into multithreading and I tried to implement it, but I can't get it to work as it gives me some 'delegate signature' related error message as you can't pass in values when trying to use 'AddressOf'.
Here is my code for the The .created sub:
Public Sub FSystemWatcher_Created(ByVal sender As System.Object, ByVal e As System.IO.FileSystemEventArgs) Handles FSystemWatcher.Created
'if any file created add fullpath to the listbox
ChangeLog.Items.Add("Created: " & e.Name)
QueueListBox.Items.Add(e.Name)

I migrated an application from Vb6 to .NET and there are still a few bugs to fix.One of them is when I want to edit a record, the inputs should have been populated with the coresponding data from the database. Instead, only the drop-downs are populated, the text inputs are blank.

I have a recursive function that causes a stackoverflow for big inputs. So I want to enlarge my stack. I have never worked with threads so maybe I'm doing something wrong but when I try to make a new thread, the description for the second argument (StackSize) says that if I use a stacksize bigger than the default one, this argument will be ignored and the default size will be used. How to increase the stacksize? Or how to create a thread with a bigger size than the default one?

working with Adobe .pdf files. I have an Adobe .pdf template that allows the user to enter text into different parts of the .pdf template (such as name, address, etc.) I have been developing a VB.Net program that is made up of a set of user forms. I would like to be able to have data that the user enters into textboxes on the VB.Net user forms write to specific areas of the Adobe .pdf template on the click of a command button. I have searched MSDN and Google but I have been unable to find any information on this particular task. If it is can you recommend a MSDN type article or any articles/books/message board posts that provide guidance on how to proceed with something like this.
