View 3 RepliesI have a very strange thing going on...I got a lot the CheckErrorStatus (Int32) error...and so I started to dig into my created functions. At the end I found what gave that error and so I added a new breakpoint on both computers where I want to run it (one is the developping computer, the other is the clients computer).
Developping computer : Windows 7, VS2008, .NET Framework 3.5SP1
Clients computer: Windows XP SP3, VS2008, .NET Framework 3.5SP1
the code of the function is a follows:

how it can that with the same input this function gives 2 differents (of which one is fault) output?
I am attempting to create an app that receives text input on a form and outputs to printer but I haven't any idea where to start for the coding. the form was relatively easy, now how to code. I have labels that give questions and 16 text boxes 5 list boxes and 10 check boxes to receive input from users how can I arrange the input into a paragraph and output to printer?
View 5 Repliesi need to create multiple threads to improve a function on my program. it is a simple thing really but it's slow and if multithreaded it can improve the speed some thousand times. my program uses a dll to check the MX record of an e-mail from a textbox called emails if the mx record is correct then it validates that domain, if not, it sends to an error textbox with that mail my problem is that im reading a lot on multithreading and i dont have an idea how to make something like this: for x=0 to emails.lines.count -1' start a thread that runs my function next if i can limit the number of threads to avoid crashing it would be good.
View 5 RepliesI'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.

I've got a little code that just reads and displays all the folders in a particular directory. What I want to happen though is for the program to pause 1 second after adding a new folder to the listbox. When I have Sleep(1000) it simply freezes completely.

I have create a CMS to upload all image to a folder using ed all my images to a folder using,
file.SaveAs(Server.MapPath("../images/") + advertID.ToString + "_" + i.ToString + fileExt)
Now, all images are saved and i forgot it create thumbnails. :(
I need to read all images at once and create thumbnails,
myimg = System.Drawing.Image.FromFile(imgFileName)
myimg = myimg.GetThumbnailImage(154, 94, Nothing, IntPtr.Zero)
myimg.Save(Server.MapPath("../Content/") + "Thumb_" + imgFileName, myimg.RawFormat)
I need this to function fast. I don't seems to know how to read these image names one by one.
I a program that you can store stocks in,such information as name of the stock, price of the stock when you purchased it and so forth.This is stored in a file that is read and can be changed.My button that displays the information is giving me some problems as I have it setup and it will read my original file but when I add files its not going to display the new files.I need a way to make it output to my list box the new files as well as the old ones.right now my listbox outputs 5 lines, and each line has 5 records now the amount of records per line will not change but the number of lines I have will.I cannot pre write lines for something that has not happened, and I am stumped on how to fix this problem..
I am still learning and new to code so for me to write code that writes other code seems like some fantasy out of the terminator so I am sure there are much much simpler ways to do this than that.I am guessing using a loop and a variable in my array than the actual number something a long the lines of csvData(i)However I am just not seeing what syntax to use and how I would go about putting this together... Never came across anythign like this in the past.[code]any thoughts for ways to attack this problem and the type of syntax that would have to be used?
I started programming 6 months ago, Visual Basic is kind of easy and I made lots of programs. Now I am confused now. I have a serious problems about DLL's but I didn't made them but I knew how to make use of them. Okay I have 2 programs and one was having a problem and other one has no problem, they have the same framework, same code, but they have problems.url...

I would like to build inputs and outputs interface board (if you have schematics for the hardware or where I could purchase such thing) I need 9 inputs and 8 outputs, 24 volte DC for the inputs and I want to build a form in visual basic that utilizes the serial port so for example when I press Button1_Click it will make output number 1 goes high in the board and when input 9 goes high in the board label9 or Button3 will change color in the form.
So basically the IO interface and the form will only be used to energize relays and monitor these relays. I am not worrying at this moment about if this input is high make this output high but if this is possible in visual basic currently running Visual Studio 2008 Express.

I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return?Going to try using /U or /A CMD switch next..

I will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.
View 1 RepliesI'm trying to do is make a program to where when you click an option, a text outputs for each button clicked, the general design looks like this:
That's just a beginning, since the whole rest of the thing will be the same concept pretty much, and what I want to have it do is, like stated earlier, once the option is chosen, a text output, like this:
I know there is an alternative to solving that, but it will take me 10x more time, and that is, creating a new textbox, setting the visibility to False, and typing what I want outputted in that text box, then putting: RichTextBox1 = TextBox1.Text
I know that works, and gives me my output, but I just wanted to know if there was any other way but that.

Is it possible to get more than one variable from a function? In my attempt below currmiles is simply being displayed in both labels instead of _currmiles to Currmiles.Text and _currdays to Currdays.Text.

View 1 RepliesI modified a function that returns a strongly typed Ilist of products (from a web search form) from a stored procedure. Because of the complexity of the stored procedure I have changed it to return productcategories as well using the product results. I can get this into another strongly typed ilist but for the life of me I cannot return the two ilists.
Unfotunatley I ran out of talent, after reading hundreds of posts, It seems it's possible with linq, but I would rather not go that way as I have even less knowledge there. Is it possible put the ilists into a collection of some sort and return them for use as ilists?

So you know how PHP internal functions usually return a boolean FALSE when a function fails, or some other data type when the function succeeds? Is this possible in VB .Net?For instance, lets say this simple code here Public Function TrySomething(ByVal Param As String) \what would go here??

You see I want to return a BOOLEAN false when a function fails, and a string when the function works. I've looked everywhere, and when I search for "return multiple types" all i find is Tuple.
Is it possible to make a function that returns both a datatable AND a list(of custom class) at the same?In my GUI layer, the main form (the application is MDI) calls this function and it has to fill the datagrid on one of its child forms and it also has to fill lot of other child forms with various information that is calculated from my custom class properties.Both the datatable and the class properties are created from the same external database and that's why I don't want to have two separate functions.
