I have this function for removing duplicates in arrays[code]...
What is happening at the moment is that the inner loop reaches the array.Remove(inner_element) line for the first time in its second loop during the second loop of the main foreach, reaches the inner next line and then just stops executing. There are no warnings / notices, the debugging step though just ends as if there was no further logic.
what is code to start program (*.exe) silently (no program icon in taskbar and no window visible)
View 10 RepliesI'm making a program that takes common applications and installs them silently using batch files. Someone would select the programs they would want to install and my program will write a giant batch file and execute it to install whatever they want. Heres the problem, After the user selects the programs they go into either one or two lists. Non Silent Installer List Or Silent installer list.
Some programs I have simply won't go silently so from there they can choose in what order they want to install these programs. Then there is a combo box that tells weather you want to install non silent programs first or last. From there you hit add to batch file and it would add everything in listbox1 and listbox2 in order. Listbox1 would contain just the text "MalwareBytes" for example. Along with Novell Groupwise and Firefox. How do I get that to add to the Batch List as a code and in order? So the user wants Malware bytes added first to the batch file. How do I add that to my batch list as a completely different code?

i have a application that i designed for an assignment which uses a DB (ACCESS) However when i publish the application it fails to load even though the application completes. I have managed to find that it is the database that is not copying over, how do i solve this (the db is located when debugging and is also in the project files)
View 3 RepliesI have compiled a project with no errors and published the release version through ClickOnce to my website, almost 5 users are working ok with the application but on 2 computers the appliication fails when a button is pressed the exception is "Index was out of range.Must be non-negative and less than the size of the collection. Parameter name : index" Note that no parameter is named index in my code and that the program runs fine on 2/3 of the computer's I there is an error why does the application compiles?Also i have send my project file to a friend to use on his own visual studio to check if it compiles and the errors appeared in the debuger despite that i havent managed to find a solution, i beleive that my code is probably ok. I'm using visual studio 2008 with Option Explisit and Option Strict On and all the deployment pc's have .net 3.5
View 1 RepliesFrustration has officially set in. This is my first post here, and to be very honest, I'll admit that I'm a newbie VB programmer as well. I guess that's why I'm posting here, in hopes you super-porgrammer types might be able to help.
I've written a smallish VB program with 2010 express... the code uses some text files to gather various lists of numbers ( as part of a manufacturing Bill of Material ) that assiciate to PDF files of the same name. The intent was simply to view and print the gathered existing PDF files.
I have the program mostly working the way I want ( at home ), but when I bring it to work, it fails to open.
My home PC is a 32Bit Windows Vista Machine with Adobe 10.1 viewer installed.My Work PC is a 64 Bit Windows 7 Machine also with Adobe 10.1. I've sent the .sln and code to a buddy who is also running a 64bit Win 7 machine very similar to what I have... he is able to run the program. I've sent the same thing to my work pc and tried to run it. I get some crazy HRESULT error I can't make heads or tails out of... remember I'm a newbie.
I will happily post code if you guys are interested, but I believe that it isn't code related. What kind of things MIGHT i try to look for on my work pc that would cause this simple program Not to function? I've brought other programs I've written to work without problem. But this one has me stumped.
Other things I've tried:
1) uninstall and re-install Adobe... ( no change )
2) written a super small adobe viewer program at work... ( works )
3) tried to comple as "any CPU", "x86", and "x64"... ( does not work )
4) bring .sln & code files to compile and run at work... ( does not work, HRESULT err )
I am constructing a program, i am new to Visual Basic, but i have past programming experience. I was wondering if anyone knew how to form a loop that could...lets say calculate the answer when two numbers are added together,and it would repeat this thousands of times, etc. And if there is a way, would it be possible to calculate the time taken to complete this loop.
View 5 RepliesNow I see that VB tells me that label arrays are no longer supported But I also see that VB2010 is providing the relevant logic to update each of the label array fields I was until today using VB2008, because after running this application it crashes with a report of stack overflow, I assume it is related to the label arrays, but have no idea. So I have upgraded to VB2010.
In VB2010, I note that the immediate window is reporting A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll Now I have used label arrays for showing columns of like data, generated by a for loop. What should I be using it its place, maybe a grid..
I assigned an integer as 1, and looped my program using:[code]I can recieve the packets without looping, but once i loop, i receive nothing.
View 29 RepliesI may be deploying my app (its a database software for videos) to 4 - 5 computers. I want to add some new features but have the software update automatically and silently. Due to security holes or issues with bugs, I don't want to give the clients the choice to update. I just want it to check for an update and if one is available, it can SAY that its updating on a label but that's about it and it automatically updates without confusing the user or wasting any more time than it should.
View 5 RepliesIf an error occurs in my application, I'd like an email to be silently sent to me with the error description (as long as the internet connection is established).
I know how to send emails in VB.Net, but I wonder what is the best way to get this done.
Is this something that should be done in a module? I could use some advice on the subject before I start coding.
Is it possible that my application, when exit, uninstalls itself automatically, without any user intervention and involvement?

I am working on making a program that will log into my internet banking site (this will most likely have to be done in IE) grab my current available balance and store this to a string, before I do any research I was wondering if anybody had anything like this already completed.I also need it to do this silently (as in no open IE windows) no visibility of program running to the user.
View 7 RepliesSo I have this in my coding:
vb
file = My.Computer.FileSystem.OpenTextFileWriter("c:command.bat", False)
file.WriteLine("@echo off")
file.WriteLine("cd " & TextBox2.Text)
file.WriteLine("adb shell dumpsys meminfo " & TextBox1.Text & " > C:Sample.txt")
file.Close()
Shell("C:command.bat")
What I want it to do is to run the batch file without it opening if that makes sense. Right now this runs on a loop for 10 minutes and on every 2 second tick it opens and then closes the .bat. Which is really annoying to see a .bat open and close every two seconds. Is there anyway to get this process to run silently in the background so the user doesnt even know that it is running?

I installed my application on another PC but it denies to work properly ! Once it is started , an error message appears saying that there is an error : "Class is not registered" . I have registered various References that up to now were reported through that error message , but at this time I can't understand what exactly is missing . By pressing the Details button I get the following message :

View 20 RepliesMakes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I would like to loop over two string arrays but does not work.[code]...
View 4 RepliesI've been having a bit of a problem using the while function.
Here is my code (Simplified):
Dim RandomNumber3 As Random
Dim RandomOutput3 As Integer
[CODE]..............
When running the debug, the program crashes, and when I step into the program, I find that this While statement becomes an infinite loop. This is a program that uses random number generators to assign a value to something, and this while statement is necessary so that there is never two of the same values showing (RandomOutput, RandomOutput2 & RandomOutput) Have to be different to one another.
