I'm looking to use a timer to change an image for a set number of times & then exit. Am trying the code below but although the TextBox check works the Image skips directly to the second from last & goes no further.

I saved an images hash number to a database so that when my application pulls in images, I can compare this hash number to the hash numbers of the images comming in. The purpose is that if one of the images comming in has the same hash number, I can flag it. It seems that the saved hash number for an image is not the same for the exactly the same image when it has come in. Is this because the hash number for an image can change depending on the pc where its being created?

I want the program to exit the sub after the timer has been started. But if theres no args, it should just show itself. The problem is that it seems to not care about the exit sub thingy, cause it shows itself anyway.
How would you make the Interval of a timer to be between two times.
E.g if you wanted an event to occur between every 7 and 20 seconds?
So, I have two timers. 1 Timer is set with an interval of 1000 (milliseconds), therefore it goes off every 1 second. For some reason, when I set the interval on the same timer to 1, it goes off 100 times every second. Shouldn't it go off 1000 times every second? What's going on?
View 4 RepliesI have this program generating a firstname and lastname from a file. When I run this program I enter information in three textboxes. The first two are the salary low and high(salary1.text, salary2.text) and the last one is the number of "copies"(copies.text) that I want.. When I put a number such as 10 in the text box it outputs some of the same names. The firstname file has around 100 records and the lastname file has about 1000 records Why is it generating the same name The problem is even worse if I do something like 1000 copies.. it outputs the same thing 8 times and then does something different another 8 times

I have a ajax Timer control. It adds "+" to the text value of a label. This timer should work only five times with an interval of "1000" - i.e, only five "+" should be available. After that, the lblPostbackType Should be updated with the count. How do I achieve it?

I've been trying to get a Timer to execute code every 50ms and it's worked okay, but for some reason after doing the code 8 times (i.e. for 400ms) it just stops. As in, won't execute the code any more times. Specifically, it's wired up to an animation (Picture) and a rectangle which moves around the screen (Box). why the timer would suddenly stop executing after doing so for a while? It's the same duration every time.

I am trying to make a timer that beeps 3-5 times and runs a progress bar. All it has to do is click start (timer set for 2 minutes starts) and as time runs out the progress bar fills. When the time is up 3-5 beeps happen. I am missing the coding for the 3-5 beeps and design parts for it and all coding for that along with code for setting the 2 minute timing. There is no label for telling the time left or to go just a progress bar. Here is my code so far.

Imagine that I have a System.Windows.Forms.Timer with 1000 ms interval. If I call Timer.Start() method and after 500 ms I call again Timer.Start() what happens? The second Start call will reset the interval or not? Are there any side effects?

Design and code a project to calculate the amount due and provide a summaray of rentals. All movies rent for $1.00 and all customers receive a %10 discount. The form should contain input for the member number and the number of movies rented. INside a groupbox display the rental amount, the 10 percent discount, and the amount due. inside a second groupbox, display the number of customers served and the total rental income.(afterdiscount).Include buttons for Calculate, clear, print and exit. The clear button clears the information for the current rental but does not clear the sumarry information. A print button allows the user to print the form. Do not allow bad input data to cancel the program; instead display a message to the user.[code]...
I have an SQL database with a single table with several colunmns. I want to count how many times a certain number appears in one of the columns. E.g. I have the following:
A B C
8 4 6
0 9 3
1 4 6
4 7 1
I want to count the number of times 4 is used in column B. I have looked at using the following, but not sure if this is even the right approach:
Dim db as New MainTblDataSet
Dim BCount = Aggregate B In db.MainTbl Into Count(B.B = num)
where num=the number I am counting the instances of (4 in this case).
The hope is that BCount will equal 2, but it returns 0 every time.
Basicly my instructor said that we have to make a program that will count how many times we enter a number into an inputbox, he also said we had to use a while loop. [code]

Also I need to know the code for putting a picture into a picture box.
I know it sounds strange but let me it explain. It has a purpose, but really all I'm looking for is the item with the most duplicates.I know it's possible and I've had a few ideas already, though none were successful or practical.What I'm doing here that requires this is creating an intuitive search for clients in a database. You type in a single field and click search. Behind scenes each keyword broken down from the single input field is searched through the table of clients, hitting each column and returning matches. the results are large in numbers, but truly it's the client that appears the same number of times as there are keywords.

How can I count the amount of times a character appears in a string?
The assignment is to create a program with 2 text boxes, label, and a button. We then need to type a phrase into the first text box, and a character in the second. Then click the button and then the label will display the output of how many times the character in the second text box appears in the first.
I have all the above setup except for how to display the amount of times the character appears in the first text box, here's a picture:
