[code]....
This code allows me to type in a number and see the length of the hailstone sequence and the hailstone sequence itself. What im not quite sure on how to do is this following: I would like to add the maximum sequence number reached in my program, but I am unsure on what to do.
New to programming completely,on VB 10 Express. I am in the process of creating a keypad which I can punch in numbers 1- 9 to enter a password. I have 9 buttons for the numbers. I've got the keys to print the numbers into the textbox above but when I press a second key it replaces the first number in the text box.
My question is, how do I make the numbers go in sequence, so instead of (Press 1) - 1 - (Press 2) - 2 - (clears 1)
I want it to go like (Press 1) - 1 - (Press 2) - 12 - and so on...
I am trying to generate autonumber the sequence is like this. From left to right, last two digit from Year, Month in numeric and the last three digit number be from 001 to 999. I tried with the below coding but the sequence is not coming correctly.
I am working on student application form in vb.net. I designed a form with fields like firstname, Middlename, Lastname, age ,____,DOB,Education.Height and Weight. Back end as SQL Server 2005. I just want to generate sequence numbers in textbox using vb.net. While loading the form,i should generate number as '1' and second time,if the form gets loading it shows '2' and goes on...
I'm using VS 2005, after VB6 to VB.NET conversion we have fixed all the errors but still have unidentified number of warnings. Is there any way to increase this limit of 101 warning you can see after compiling? I want to actually see the total number of warnings to get an idea how much work is there.
My issue is that some websites only allow say 15 characters maximum to be used to create a user name where other sites do not. Currently I have one text box on the screen and a button, and a web browser that navigates to two sites.Site #1 has a cap of 15 characters max to create a user nameSite #2 doesn't have any maximum amount of characters to use.I am wanting to know how I can enter lets say a 20 character username into the text box and have the code set a max of 15 characters for site one and nothing for site 2. I was thinking that this could be done when passing the information from the text box to the text box on the screen with something like
Textbox1.Text.value.length= maximum 15 Site #2: Textbox1.Text
What is the maximum number of executions in a while loop in VB.net that it will allow? Meaning, it is checking for a variable to equal some value, but that value never comes? How many times will it execute the code before it quits? Is there some way to set the maximum number of executions without terminating it programmatically?
I am writing a matching program, and need 24 objects to randomly appear, each twice, across 48 spaces. I figured the best way for me to do this would be to assign the positions a number 1 through 48. but the problem is I can't find a way to generate a random number sequence in visual basic 9 .netI found many examples in visual basic .net but the conversion doesn't work. If not some code, many some example programs that either use a random number sequence or randomly sets the position of objects.
I have a timer that basically counts a number up in sequence in a label. On the On Text Change sub for the label I have functions run when the label is at a specific number. Everything works fine, the only problem I have is I have information pulled from an ODBC link to a pervasive database every second, which slows down the program. I have several flash components that run so slowly because of the data update. Now I have tried both using a dataset and coding the query but it is still ver slow and processor intensive, I think its because the Pervasive ODBC link is somewhat slow. Is there a way to have my data pull timer run in the background so that it doesnt effect the performance of the rest of the program?
I'm trying to figure out a good way of implementing a List(Of) that holds a maximum number of records.
I have a List(Of Int32) - it's being populated every 2 seconds with a new Int32 item.
I want to store only the most current 2000 items.How can I make the list hold a maximum of 2000 items, then when the 2001'th item is attempted to be added, the List drops the 2000'th item (resulting in the current total being 1999).
Thing is, I need to make sure I'm dropping only the oldest item and adding a new item into the List.
one of our programmers is having an issue with a asp.net app. i had him rebuild and recompile the app to the network share on the staging server and received the same. i even deleted the files in this folder(C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). to make sure that the server was not the issue i installed it on another server and received the same error.i found a article on msdn that states that its a source code issue.
Compiler Error Message: BC30041: Maximum number of errors has been exceeded. Source Error: [No relevant source lines] Source File: vbc : Line: 0
I have been looking all around Bing and Google trying to find this, does anyone have an answer? How many line continuations will the compiler tolerate in VB.NET 2010 (.NET 4)?
i am trying to put a maximum row number of lines in a multiline textbox. What i want is to achieve something like a console, with a maximum number of rows, with the top rows to dissappear and to keep always the last i.e. 500 rows. a note: for the textbox text i use the following algorithm
dim text textbox.text = textbox.text & vbcrlf & text
the problem is that after a certain number of rows the program starts to get a little slow. So i guess if i put a limit to the rows i will fix this.
I developed a client-server application using soket technology. At this moment the number of clients that connect at the same time is 40. Question: What is the maximum number of clients that can connect simultaneousl
Im wanting to use a textbox for the entry of Decimal figures (currency). Is there any way I can have it so if a user does not put a decimal figure (ie 15 instead of 15.00) it will put it on.
I tried a masked textbox, but that means i have to set the maximum number of digits before the decimal too which is no good.
Write a function that will take one integer input parameter, create a sequence of numbers stored in an array from 0 to that number, and the numbers are a summation. For example, given 7
In a project I'm working on, I've assigned each user a unique ID with the following code. [code] However, I want to replace the number at the end (RecordCount) with a randomly generated sequence of 4 numbers (no 2 can be the same).
I'm trying to write a function which obtains the sequence_number by counting the records in a table that fit a particular criteria and if the result is 0 or nothing sets a variable to 1 but if the result is 1 for instance, the variable will be set to 1 + 1.
This is the code i'm using but i'm not getting the correct result when results are actually returned. For instance, if the result of count is 1, i want "seq" to equal 1 and total (which represents the sequence # assigned to the next record which is entered with the same plan and date) would therefore be 2 which is the result of seq + 1 (i.e. 1 + 1)
I have this app to copy files with a progressbar... What I'm trying to do is to set the progressbar1.maximum to the number of files in the folder. But I'm getting a cross-thread error. This is the error I'm getting: Cross-thread operation not valid: Control 'ProgressBar1' accessed from another thread than the thread it was created on. This is where I'm trying to set the ProgressBar1.Maximum: [code]
how can i code a simple program to generate the maximum number i enter/type within 3 or more numbers using math.max. for example, if i enter 25, 60, 45 how can i use math.max to calculate the largest value out of the 3 numbers?
