View 10 RepliesNeed help removing a copy of my program shown on the Task Manager after I close.
I must kill a conflicting program that cannot share the COM port and then reinstate when myprogram ends. To reinstate I use: System.Diagnostics.Process.Start(conflictingPath & conflictingProgram)
In the last line of my Form1.Closed I try to end all with:System.Windows.Forms.Application.Exit()
Not working - each time I run this program it does kill the conflicting program, can do its dialing function and upon closing reinstates the conflicting program. But each time another copy shows under Task Manager.
I'm trying to, from a client-side piece, call off to a server-side piece. I need to do this synchronously. On my server-side code, though, I'm calling off to another piece of code, which I want to have a maximum of, say, 10 seconds to return a value. If I don't have a response within 10 seconds, I want to force my own server piece to set my result equal to 0, and return to the client.
Here's what I have on my server-side code so far:
Public Function GetWebResult(ByVal inputParameter As Object) As WebReturnObject Implements IWebInterface.GetWebResult
Dim result As New WebReturnObject
Dim webItem As WebItem = Nothing
[CODE]...
I realize this code is not functional. The problem is that I'm unsure how I would go about getting back into GetWebResult to set the appropriate return values before it is sent back to the client.

I am running an experiment that datalogs to the computer. I need to know when there is a change in on of the databoxes. Since there is no way to modify the software, my mind thinks the next best thing would be to design a software that allows you to select part of the monitor's screen and have it refresh very quickly to detect any change in the image in that area.

I have a modal pop up that is supposed to upload documents.

View 1 RepliesTI have a picturebox on top of another picturebox, like a smaller square perfectly in the middle of a lil bigger square picturebox, if you click on the smaller one inside the slightly bigger one, it checks to see what the color is of the picturebox "under.It", or the Picturebox thats bigger than it, and is like sourounding the smaller one in the middle of it... If when you click the small one, and the BG Color of the one that's under it is Black, change it to white, "my forms bg color is also black"....so the highlighted pictureboxes will seem more like they get highlighted, ya know...
Here's the code, after you've looked at those pictures, you can probably imagine what I want this code to do, and it's really Guiness really, because when I program in VB.NET, and before I go to YouTube to teach others how to do different things with VB.NET,I like to make sure that my program is very simple, but very effective, and does the job.When I click two pictureboxes, and when my app knows that I have clicked 2 of em, which I had no problem being able to do, I want the FIRST PictureBox To Switch With The Second One That Gets Clicked, It's CHESS....It Seems So Damn SImple, BUT I'M STUCK AGAIN, AND I WANT TO MAKE A CHESS BOARD IN VB.NET.
my situation is this; I have a search button which searches records with Surnames, when two or more records have the same surname, the first record appears and 4 navigational buttons appear, they are 'Go back to first record' (btnFirst), 'go back one' (btnPrevious), 'go forward one' (btnNext) and 'go to the last one (btnLast)'. All of these work properly except for 'go back one' (btnPrevious). When I click this and the record is currently the first one, the program crashes. Its probably a very elementary mistake but I can't figure it out. Here is the code for btnPrevious

View 1 RepliesIn an attempt to try and make a chess AI I started working on a chess project. The AI will basically be in a class that implements my AI interface. To provide flexibility this can be used for a human player or a computer AI. In any case the problem I'm having is calculating the valid moves that a single piece can have.I calculate on what blocks the piece would be able to move if the board was totally empty. (this is represented by a array of point)Then I get a list of piece locations of the same team and Except that from said list.(since pieces can move through other pieces of its team)Now here is the tricky bit obviously taking an enemy piece is a legal move I can't just subtract enemy piece positions. Lets say there are 2 black pawns and a white rook in the same column. The rook would be able to take the first black pawn but not the second one because the first pawn is in it's way. In reality there would never be such an easy example so I need a way to only include the enemy positions "In the line of sight" of the piece's moves i'm calculating.

I am trying to import a text file into a data table using VB.NET. I need to loop thru each line of the text file and put certain elements of that line in a new row of the data table. The line may contain 50 elements, but I only need to get 15 of them. The very first line is a header row, which contains "File Name", "Object Name", "Object Weight", etc. The trick is the element locations move from file to file. For example, "File Name" element may be located at 0 in one file and then 15 in the next file. I need to find the exact location of my desired elements and save them to a variable. Then use that variable to locate the exact piece of data in the text file line to place in my new row.
The code below obviously doesn't work, but it kind of illustrates what I need to have done.
Try
With dt
.Columns.Add("fltObjectWeight", Type.GetType("System.Double"))
.Columns.Add("vchObjectName", Type.GetType("System.String"))

I am trying to successfully multithread a piece of software I have been working on. I have an array of threads 'gen' already working, calling to a method taking a single integer as a parameter (done via typecasting).Now in this thread, when the function gets processed (for each thread a roughly 500 iteration while loop) the index seems to be getting mixed up. As far as I can tell, my threads are messing with eachother and warping values. Now this is happening in locally declared variables inside this function, not global variables.It may be useful to know that I am using a WebRequest via a call to another method. Don't know if that makes a difference or not.
