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.
I have 10 labels with 10 numbers and i want theses numbers to compare with other 10 labels with different numbers and when they found that second pair of labels are not equal with the first to show me in a new label where is the fault and in another new label the sum of the mistakes

I'm trying to match a string to see if it matches exactly this:####-####, it has to be 4 digits followed by a hyphen followed by 4 more digits. Right now I have this pattern: "d{4}-d{4}" but it's allowing 5 digits in either (or both) instead of strictly 4 per group. Here's an example of what it should allow:
1999-2000
2003-2007
2009-2010
and here's what my pattern is allowing but should not be allowing:
20081-2009
2009-20101
12345-12345
12345-1234-1234

View 6 RepliesFor some reason I can't figure this out. Here's my code. colorTextbox.Text =Format(Hex(ColorBox.Color.G), "00")What I want it to do is format the Green Hex number to be "00" instead of just "0" when the color is something like blackhis has proven to be very stressful and this Format command makes no sense to me anymore (worked differently in 2005).For one, whatever I put in the quotes ("00") is what comes out in the text box. Butaccording to the command parameters, "00" should be the format, not the actual text! So then I tried any string format I could think of (## etc.) along with switching the order and I STILL can't figure this out.
View 16 Repliesis there a way to make VB 2008 read a text file of digits eg:
56154131313313
31231212121211
12534645456464
44564545454787
and import it into vb, splitting it into four digits and putting each set of four digits into a different text box.
code to make a text box only except 4 digits and only integers.

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.
Inside one of my functions, i load up an xml then retrieve the relevant data like:

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 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.
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.
