View 19 RepliesVS 2008 Counting Down From 30 Mins?
Feb 7, 2010I'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.

Jan 8, 2012after reading a topic that Chris Rutland wrote about student in final year (link)[URL]...So i was able to complete this in roughly 15 Mins give or take. it also said multiples of three and five. Which i would have understood as 3 * 3, 5*5 as so on, but when I thought about it they would never match within 1 - 100 so I took I must have misunderstood so I then done it as 3 + 3 and 5 + 5 and so on.

Hide/Show Items - Possible To Hide A Group Of Text Boxes From View In A Form
May 5, 2012I'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

So for example,95430 seconds should equal 26:30:30 (hh:mm:ss) however comes out at 02:30:30.Here is the sample code, note I have tried using TotalHours, TotalMinutes TotalSeconds however this does not give the correct result.

View 7 RepliesName Change For Form1?
May 24, 2011I may have corrupted my Visual Studio Software. I have two problems which may be related. The first is when I open anew project, I can't change the name of the form. I enter frmXXXX and it returns a splash box indicating I may loose my programming. If I continue the program gives me an unusable form. This happens when I have not even begun to use the form. My Visual Studio is set up to work with Visual Basic only.
Secondly, when I try to incorporate events, I can not get them to function. Using the basic form set as Form1, the Load event will work, but it enters as "Private sub Form1_Load ........ Handles MyBase.Load not Me.Load. When I try to use the events: KeyPress. KeyDown Or KeyUp, I can't get them to function. They also are entered as ........ MyBase.KeyPress. To enter an event I go to the Properties Menu, and use the event enry, click on the function, then double click the function. The sub-routine is loaded into the program, but doesn't function. I am learning by using a text book that the same programming works in a demo which was downloaded.

Picturebox Shows A Red X?
Nov 13, 2011After my code runs for a while (i.e., 1+ hours), a picture box that was being displayed properly switches to showing a red X. The surrounding code still runs, but the image is not shown. I was intermittently having an out of memory error, but recent changes may have addressed this issue.The application is capturing a webcam image of an 8 x 16 grid which can hold different color balls. It displays the live image in picturebox1 (this works). I then grab a still from the live image, process it to see if there is a colored ball in each of the grid holes, and draw a representation of the image in picturebox2 using a grid of colored circles. As the live image changes, so does the drawn image. The drawn image is updated about 4 times a second. In each cycle I trigger a redraw of the image with a PictureBox2.Refresh.
Everything works great for a while (about an hour), but then picturebox2 gets the red X. The code keeps running without throwing an error. The live image still works.Recently I was getting an OutOfMemory error (again after an hour), but memory usage should not be growing in the code, and I have 8 GB installed. To address this issue I
1) forced Garbage Collection every 30 cycles (this does not seem to help, but I left this in the code.)
2) Inserted a Picturebox2.dispose before the Picturebox2.Refresh, but the Dispose took the picturebox off my form. I removed the .Dispose.
3) Moved declaration of variables out of loops to top of subroutines. (that seemed to get rid of the OutOfMemory problem.)
4) Inserted various try ... catch statements, but the code does not throw an error when redrawing the image, so this did not help.

View 1 RepliesCall One Form1 And The Other Settings?
Apr 1, 2010My program has two forms. Let's call one Form1 and the other Settings. It's possible that Settings may be opened before Form1. Settings may also change some settings that need to be updated immediately on Form1. The thing is, if Form1 hasn't been opened yet, certain elements haven't been fully initialized (even tho Form1's properties can be modified since I do create an instance of the form on program load). Since these elements haven't been initialized, if Settings tries to modify them, it crashes the program.
Are there any ideas how, maybe to keep Settings from modifying stuff on a form that hasn't been loaded yet for the first time.
