I'm redoing a program I made up a while back and need some help changing a loop. The original program had all the text boxes on same form, the redesigned program still has them all on the same form but I have them spread across multiple tabs and the background of the form.
The code below loops through each possible text box and if it exists sets the value in an array. This only works for text boxes not on tabs. I found I could change the Me.Controls to TabPage1.Controls and that would get the text boxes on tabpage1. I would like to have a single loop that can find them on any tab and off the tabs, so I don't need three separate loops.
For num = 1 To 61
For Each controlctl In Me.Controls
If controlctl.Name = "TextBox" & CStr(num) Then

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<
Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.
My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.

I am stuck again. I have an Access database file which list all the players for a baseball team. The player age range is from 12 to 14. I need to be able to click a button to count how many players are in each age group and dispaly that information in three separate labels. One label for each age group.
I have learned how to count rows, but how do I count rows containing certain data like 12, 13 or 14. I also know and understand how to get information to display in a label. I need to know and understand how to count just certain records.
I have an assignment in which I have to generate random numbers and use arrays to count single digits. I've finished everything the random number part but am stumped for the digit counting. What expression would I have to use?
I've got my labels for the counters as lblZeros, lblOnes etc. but can't seem to get any further with the coding.
If I want a label that is counting something to go up by 1 everything it does something "1,2,3,4 etc" how do I do that?

View 1 RepliesI am in a "survey of programming languages" course and have a professor who doesn't teach. There is no text book for this course.I am working a VB Form project to take a URL, grab the HTML source code, parse out all words, and count the occurrences of each word on the page. I have built the form, and written the code to parse the words and store them in an array. What is the most efficient way to count the occurrences of each individual word in that array (case insensitive), sort the results decreasing from most frequent, and display the results of the ten most used words. I will be displaying the results in two separate listboxes on my form. 1 listbox shows the words, and the other shows the number of occurrences.

I have a listbox with the numbers from 1 to 20 in it. If I add one of these 20 numbers, the number should be added in the richtextbox and they should be counted together with the last outcome I had. And this new outcome should be shown in label "lblTotal. If I add a new number into the richtextbox with this button. This new number should be added under the last number in the richtextbox and it should counted with the last outcome I had. This way I can count how many points I have.
how to get the form to save some data, but the problem is I only know how to get it to save as the body. since the main parts of the program are third party, but here is the code I'm using to save data.
Private Sub Initialize()
' cmbLabel shows group(student) level
cmbLabel.DataSource = _schedule.DataStorage.LabelStorage.Labels

Since I have them all saving to the "body", whatever the last box is in the code is what shows for all three once I click save.
This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.
I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out. The last line for the MessageBox is causing me problems.
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?

View 6 RepliesI need an accurate timer to interface a Windows application to a piece of lab equipment.I used System.Timers.Timer() to create a timer that ticks every 10 msec, but this clock runs slow. For example 1000 ticks with an interval of 10 msec should take 10 wall-clock seconds, but it actually takes more like 20 wall-clock sec (on my PC). I am guessing this is because System.Timers.Timer() is an interval timer that is reset every time it elapses. Since it will always take some time between when the timer elapses and when it is reset (to another 10msec) the clock will run slow. This probably fine if the interval is large (seconds or minutes) but unacceptable for very short intervals.Is there a function on Windows that will trigger a procedure every time the system clock crosses a 10 msec (or whatever) boundary?
UPDATE: System.Timers.Timer() is extremely inaccurate for small intervals.I wrote a simple program that counted 10 seconds several ways:
Interval=1, Count=10000, Run time = 160 sec, msec per interval=16
Interval=10, Count=1000, Run time = 16 sec, msec per interval=15
Interval=100, Count=100, Run time = 11 sec, msec per interval=110
Interval=1000, Count=10, Run time = 10 sec, msec per interval=1000
It seems like System.Timers.Timer() cannot tick faster that about 15 msec, regardless of the interval setting.Note that none of these tests seemed to use any measurable CPU time, so the limit is not the CPU, just a .net limitation (bug?)For now I think I can live with an inaccurate timer that triggers a routine every 15 msec or so and the routine gets an accurate system time. Kinda strange, but...I also found a shareware product ZylTimer.NET that claims to be a much more accurate .net timer (resolution of 1-2 msec). This may be what I need. If there is one product there are likely others.
I have a timer on a page in ASP.NET.
After a certain period of time elapses, I want to disable the timer.
I want to put a static variable in the timers tick event that will track how many seconds have elapsed.
My question is, will this work?
If user X and Y are viewing the page will they both have separate local static variables?
What is the best method of shutting down an ASP.NET timer after a certain elapsed time?
