Continuous Message Box?

Sep 27, 2010

I am trying to have a box in the corner of my form that has continuous words added on it. Basically I want it to look like this: (each line would be added on as it occured in the form.

You entered the Castle.
You exited the castle.
You enter town.

Using messagebox.text = messagebox.text + You enter town I can get it to look like this in the box:

You entered the Castle. You exited the castle. You enter town

Is there a way I can make it so that each time something is added to the box, it appears on a new line?


Continuous Transmission Of A Character?

May 12, 2010

I've wrote a program that send and receives data via a serial port to a microcontroller. At present when I click (from a menu strip) a certain option I send data such as

Private Sub MsToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MsToolStripMenuItem.Click
End Sub

What I am wanting to do is instead of sending the data just once when I click this option, I want it to repeatedly send it until I select another option where the same occurs again and so on.Is there a function that acts like a while (1) loop that can do this?

Output Continuous Sound NOT A File?

Nov 2, 2011

I have a data source that creates a continuous stream of 24-bit samples.  I can collect a set of samples and build a .WAV file, and play the file through my speakers.  What I want to do is eliminate the middleman, and send the stream of samples directly to the sound card.  The data source can run for hours or days.  I want to hear it in real time, rather than collect it all and listen to it after the fact.  The idea is that I can tune the process that creates the data better if I can hear what it's doing.

Output Log Continuous Scroll To Botton?

Mar 16, 2011

I have a textbox that is constantly updating (a log). Every time text is input the textbox is scrolled to the top. I need the textbox to always be scrolled down. Seems simple enough? Im scratching my head on this one. I tried the following code

Private Sub Timer22_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer22.Tick
Log.SelectionStart = Log.TextLength
End Sub

But the problem is the scroller jumps sporadically because it bounces to the top and then bounces down and it makes the program look sloppy.

Button Interrupt To Stop Doing Continuous Event?

Apr 27, 2010

I have an event I want to do continuously until a button interrupt is pressed.
Here's the pseudo
Click button 1:
Check if button 2 is pressed
If not, do stuff
If so, stop doing stuff
End routine

So what I currently have is this:
Dim randominteger As Integer = 0
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles StartSampleButton.Click
[Code] .....
Unfortunately, it's never breaking outside of the first loop. How to get around it?

VS 2010 - ProgressBar Added And Set To Continuous Style

Jun 20, 2012

I have an application that has a ProgressBar added to it set to Continuous style. Everything seems to work great except that the progress bars seems to "fill in" slower than needed. As a test, I created a form with a continuous progressbar and a button. The button code only sets the progressbar's value to 100 (which is the max). Basically, for the test, the value changes from 0 to 100, but the ProgressBar seems to incrementally fill in like it is doing a PerformStep or something. I don't get it. Is there a way to get the ProgessBar to go from empty to immediately full when setting the value from 0 to 100 without the animated filling?

Printing On A Continuous Paper Through A Thermal Printer Using Crystal Reports

Mar 11, 2010

I'm trying to take a print on a Continuous Paper through a Thermal Printer ZP 2844 using Crystal Reports 2008 along with Visual Basic .NET 2008. I've set the page size to 3.00 inches as width & 3.00 inches as height. It prints well when the contents are a few on a single page but it puts gap when printing more than single page. There's no page margins set in crystal reports & the printing setup is the same in Crystal Reports as well as in Printer's Setup. Even in Print Preview of Crystal Report, it shows 2 pages to be printed but there's neither any gap at the end of first page & the start of second page. But! Still, a gap is shown when the report is printed. Here's an example how the print is show:

Product Qty Amount
Item1 1 100
Item2 1 100


You can notice the gap between Item3 & Item4 which is due to next page or page break or so. I've noticed that in Crystal Report Viewer for Web, there's an option of SeparatePages = False which let you have a single/continuous page printing but I've not found any such option in Crystal Report Viewer for Desktop.

Implement A Continuous Http Stream Which Uses The Same GET Request But The Connection Stays Open

Oct 26, 2010

My app currently sends GET httpwebrequests and parses the content after reading the response stream for each request and the repeats this process over and over. I need to implement a continuous http stream which uses the same GET request but the connection stays open, from what I understand. how would I change my existing code to do this?

The streaming HTTP implementation allows one to cosume data in real time over a single persistent HTTp request. It access a data feed that continues to send activities on that response. I need to read data from the response, process it(parse and store) and then continue reading from the response and continue this process until the connection is closed. Would this be like a asynchronous request instead?

Results Should Be Displayed In A Message Box But Message Box Does Not

Nov 16, 2009

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

VS 2008 Decoder - Type A Message In The "message" Text Box And It Spits Out A Code In The "code" Text Box

Dec 24, 2009

I'm making a simple decoder. Type a message in the "message" text box and it spits out a code in the "code" text box. If you pop a code into the "code" text box it spits out the message in the "message" text box. Seems simple, right? Well here's my problem. I typed "The quick brown fox jumped over the lazy dog" to test it and it will put a lowercase "f" at the beginning, put letters that aren't supposed to be in there in there, and replace what should be upper case letters with lower case. I commented out the code for replacing symbols because it seemed to work fine before I put them in the code but still the same result. I checked over the code to see if I mixed stuff up. Like I accidentally put the replacement for a lower case "e" as the replacement for a lower case "h" but I can't find anything.
