Place Code In .Net Solution That Will Execute Continously?
Jun 29, 2011
I'm new to .NET so please forgive me if my question doesnt make sense.I'm working on a project where the difficult part is already written. I have the classes for comms drivers and can use the properties and methods with expected results.What i need to do is perform a task every 500msec regardless of which form is loaded. Is there some sort of "module??" I can have running continously every 500msec? Off a timer event perhaps?
These variables should have global scope throughtout the application so I can access them from different forms.

We have a couple of DLLs that need to be put in the GAC at compile time only in Debug mode as this is what developers use locally. Release mode will be the Continuous Integration server build and we will not want to put any dlls in the GAC. We used to do something similar with post build events on a project, but if a post build event can be conditionally run if debug. What is the best way to achieve this?

Like I imagine everyone, I often have problems navigating my code because the flow can jump from place to place. For example, if my code calls routine1, and I then want to go to routine1's code, I know that I can click in the dropdown menu and it will take me to that sub. But wouldn't it be easier if I could somehow right click on the call to routine way and select something like 'take me there' which would transport me from the function making the call to the code for the function being called? Then it would be easy to hop from place to place.

When the button is pressed, it all works and the following files are created: yahoo.dll and yahoo.pdb My question is this: What is the code to load the already compiled yahoo files to execute the code again, without having to recompile the code?

I want to import my data, which I receive over USB (every second), to an Excel sheet. Thing is, I want to open only one Excel file and write everything to this one file, and by pressing a "STOP" button, data reception will be canceled and data in the Excel file should be saved and Excel file should close right after that. Here my code,
Dim excel_cnt as Integer<br/>Dim sv_var as Integer = 0<br/><br/>Sub write_to_excel()
Dim xl As New Excel.Application

Between testing sessions on my windows service, I'm changing code (little tweaks here and there). For more detailed debugging, I've had the application send messages to a text file everytime it does something (executes a new procedure, catches an exception, etc).
I've been doing this for a while, but ever since yesterday, it appeared that the new code wasn't being used. To test this, I changed the name and location of the log file that the service would use, and re-installed it shortly after a new successful build. As it turns out, the service is writing only 1 message (about a timer being started - which is only supposed to happen after it's logged the start of the service) to the old text file. It looks to me like my service isn't using the new code in my Service1.vb file, Like the old code has been cached or something, and the service is installing from that.

I'm having troubles finding where I can put code-behind for my dnn pages.[code]...
However, I want to be able to add a VB function that is executed on Page_Load, so I made my own code-behind file. But I can't take out the current control (one referencing skin.vb) to put in my own, and you can't have more than one Control.
I also tried embedding the code in a tag, but I need to do some Imports which give me an error saying they must be declared at the beginning of the file etc etc...
Anyone know how to properly add code-behind for DNN pages?

Been spending some time on Codility.com recently and it crossed my mind; how do they execute the code you have created (Specifically pertaining to C# and VB.NET) ?
What I am basically wondering is how would I take a textbox on a form type some code in it and then run that code? Is this possible without 3rd party tools?

Can anyone think of a clever way to execute a piece of code every time a form opens, application wide? I have an app with about 45 screens, and I don't want to drop code in each form load event.

how to run code "in the background".As a form is loaded into memory I have the following code filling a listbox from a database table with this sub.I read in one of the documents about making code efficient that I could make this execute in the background.The list box is not needed immediately.

I have an app that allows a user to type in code that can be executed much like vba code in the office world.I currently execute this code with the Proprietary Dexterity code used with MS Dynamics - GP.However, my users need to be able to run outside the Dexterity world.The easy answer is to allow them to type in vb scripting or vb code instead of dex code.However, I can't find an easy way to dynamically execute their code within my methods.CodeCom looked like it could be the answer, but If i'm reading it right, I would have to know what libraries the user is using in their code for vb.Thus, I thought to simply limit them to vb scripting.Unfortunately, I can't find a way to execute vb scripting from within vb, (all the articles are ancient and most links fail - thus I gotta believe there is an easier way).I'm at a deadline where I developed the prototype but trying to use sql statements failed miserably when trying to execute.

I am totally new to VB2008, so please bear with this likely dumb question.
I have seen numerous "my first program" tutorial that show you how to create your form, put controls on it, etc. I can get through those just fine.
However, I am wondering: If I compile a set of subroutines into a .exe, how do I indicate which code/sub to execute initially? I am an old school programmer (remember COBOL?), and we always had a starting point; a set of code execute, that initiated execution of other subroutines, functions, etc.
I have dabbled in VBA for Excel, and MS Access, and even those, you indicate in the interface, and menus you create, that first bit of code that brings up the menu, or perhaps the program's main interface.

I have a user control which is essentially a main menu I can place it into my MasterPage hard-coded, but I don't want that, I want to be able to dynamically place it with the code behind of the MasterPage.
<controls:mainMenu ID='MainMenu1' runat='server' />
So what I am looking to do is something like
if **condition is true ** _ response.write('<controls:mainMenu ID='MainMenu1' runat='server' />')
Of course, I know that won't work, but how would I place the control based on a condition in code behind on the master page?

I'm trying to familiarize myself with network programming, and what better place to start than designing an FTP client code library?So far I'm not doing very good. I'm trying to create a method which downloads a file from a remote server to a local file path. To do so, all the examples that I could find declare a byte array that serves as a data buffer. I completely understand the point of doing that, rather than reading and writing byte per byte, but I just can't get it to work. Whenever I set a buffer greater than 1 byte, the output is somehow corrupted (different checksums, media files won't play etc).[code]Because this code does work when I set the buffer size to 1, I feel like there's something going wrong with the byte order. But all of this code is synchronous, so how is that even possible.[code]

I'm trying to accomplish something fairly simple in VB that I do everyday in JavaScript.I need to parse text between two strings (HTML tags mainly) that have multiple occurrences.
Sample Data:
<tag>test</tag>
<tag>test2</tag>
<tag>test3</tag>
If I wanted to grab the data in the 2nd <tag> in JavaScript I would simply do this:
var result = string.split('<tag>')[2].split('</tag>')[0];
And the only way I seem to get that to work in VB looks like this...
Dim from = string.IndexOf("<tag>")
Dim [to] = string.IndexOf("</tag>", from)
Dim result = string.Substring(from + "<tag>".Length, [to] - from - "<tag>".Length)

I have some code that access an API out on the web. One of the API's parameters allows me to let them know that I am testing.I would like to only set this parameter in my code when I am testing. Currently, I just comment the code out when I do a release build. Is there an automatic way of doing this based on the build configuration?
