Convert A Delphi Copy Operation To A .Net Substring Operation?
Jan 4, 2012I'm trying to convert code from Delphi to .Net. I'm stuck on one line:
//Delphi code ss := Copy(ss, Length(ss), 1) + Copy(ss, 1,Length(ss) - 1); 'vb.net code ss = ss.Substring(0, ss.Length - 1) + ss.Substring(1, ss.Length - 1)
Delphi combines the two substrings, while .Net just concatenate them like a copy.
Can't Seem To Figure One Out?
Nov 24, 2009My programming days are many years in the past - so I'm trying to get back into it. My current problem is as follows - I have a word document that is set up as a mailmerge document that is merged to email (through outlook). The merge records are in an excel spreadsheet (the email address is in a field called EMAIL). My emails are getting rejected by the recipient domain because they're being sent too fast (so they therefore think that they're spam).
I need to create a VB Program that will use the document called MASTER and merge it with the spreadsheet called RECIPIENTS and send via Outlook. However, I need it to send the first 10 emails, wait 10 minutes, send the next 10, wait another 10 minutes and continue cycling through until all of the emails have been sent.

Jun 22, 2010I have two text boxes, submit button. and a dropdown list with the items(even, odd, and all). I want to calculate the sum of either all "Even", "Odd" or "All" numbers according the selection. In the code below, I have the "all" section working correctly but I'm trying to figure out a way to get the Even and Odd to work.
Some one suggested me to develope a good formula for determining whether a number is even or odd, then calling that from within the program as needed. I've tried that below with the IsEvenNumber function but got stuck. Protected Sub btnSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnSubmit.Click

Figure Out The 'bytestowrite' Command?
Dec 1, 2009I'm trying to figure out the 'bytestowrite' command, but I'm not having much luck.I'm sending some info over COM1 to and LED sign, and since it runs at 300 baud it takes a minute or so to transfer. I was trying to use the 'bytestowrite' command to find out how many bytes still needed to be sent, and use that info with a progress bar, but I'm always getting 0 when using 'bytestowrite'
Below is the code I tried to get the bytes left to write into a label box, but I've probably got it wrong (but I like to try to figure things out before I ask for help).
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
Using com1 As IO.Ports.SerialPort = My.Computer.Ports.OpenSerialPort("COM1", 300, Ports.Parity.None, 8, Ports.StopBits.One)
Label1.Text = com1.BytesToWrite
[code]....
I thought putting it in a timer would keep checking the com port to see if there were any bytes to be written, but it always shows 0.

Feb 18, 2010I found this code on here while doing a search and would like to be able to use it but it was written in C and I dont know much about that (don't know that much about VB.NET either but trying to learn)[code]What I do have is a text box where a user enteres a desired number of US dollars to convert to three types of currency.I know how to convert the string entered to an integer so the calculation can take place. What I don't know how to do is modify the above code so that the results will show up in the correct text boxes after each calculation (yes I know I have to convert the integer back to text).If someone could show me how to do the first Select Case I can figure the rest out.

View 9 RepliesFigure Out Different Ways Of Making Programs Work?
Jun 22, 2010I've been going through a VB book I had while in College, and was trying to figure out different ways of making programs work.One assignment was to create a multi-dimensional array to figure out wind chill factors. The only part I really can't get to work right is using 2 numericUpDown controls. Using 2 dropdown menus was obviously easy because the items are indexed, but as far as I know, numericUpDown controls are not indexed.
Instead I used 2 selectCase statements to determine the index in each updown control, then passed the indexes to a function to determine the answer.The numericUpDown controls both increment by 5, (wind from 5 to 30) (temp from -20 to 15)Just looking to see if someone has any ideas of a better way of doing this.

Figure Out The Taskbar Height Without Using Screen.WorkingArea?
Sep 7, 2011I've got a form that's supposed to position itself at the far right edge of the screen, and stretch in height to fill the whole heigth of the working area.Nothing too strange about that, and so I wrote a solution using Screen.WorkingArea.Height, which worked fine as long as I ran locally. The snag is that in production the form is run in a Citrix environment, and it seems to completely ignore the taskbar height. In Citrix Screen.WorkingArea.Height returns the exact same value as Screen.Bounds.Height - thus stretching itself under the taskbar.My idea is to use Screen.Bounds.Height (as that seems to be returned correctly) and subtract the taskbar height on my own. Only problem is the only examples I can find on how to do this involve Screen.Bounds.Height - Screen.WorkingArea.Height.

I have no probs with general filtering and using data adapters to access the data. But im struggerling with the loop side of things.
VS 2010 Weird Error Even Teacher Can't Figure Out?
Apr 23, 2012i made a program in which you put in a number like 10, and there are 10 cards. If you put in a number like 23, here is a possible output -
Card #1 - 3
Card #2 - 20
the rest 0
etc, where all the cards values adds up to the number you submit (the values displayed will be random)
The thing is, when i do a number below 10,000, it will come up as one card equaling that number and the rest equaling zero. If i do it a number 10,000 or larger, it will split it like it is supposed to.
[Code]...
interestingly, if you put in a break point, it works like it is supposed to!
What is going on? And why does it matter the size of the number for it to matter?
When i get home i'll edit this with screenshots.
Game Programming :: Cant Figure Out How To Plot Gps Points In Directx
