Setup A Subroutine In VB To Go Through An Array Of Records?
Oct 20, 2011
I am trying to setup a subroutine in Visual Basic .NET to go through an array of records and remove all records where the date field is before the current date.Here is my current code:
Sub FutureDate()
Dim movefrom As Integer
For x As Integer = 0 To UBound(notifications)
[code]....
After this sub is called, the program shows the first three records in the array in message boxes (for debugging purposes).However, when I run the program, the message boxes are never displayed. This sub is definitely the problem, as commenting out the line that calls it fixes the problem, and the appropriate messages appear, albeit with the first box containing a date in the past. This is for a notifications/upcoming meetings system, so I obviously don't want to include dates that have passed.The records are already sorted by date, so to my eyes this should do what I want it to, which is remove the records with dates in the past, move everything else to the front of the array, and then remove the spaces at the end that the records were moved from.
I have an old program written in VB6. I upgraded the program with VB 2008. The updated program works fine except when the program tries to transfer an array to another subroutine. The old VB6 program sends arr(0) as an argument to the subroutine, the address of arr(0) is passed to the subroutine. The array arr() address is the first of a block of consequent addresses one by one, arr(1), arr(2), etc.
Now when running VBnet, the address of arr(0) is not the first of all consequent arr(1), arr(2), etc. It is an isolated number, just like if arr(0) were a variable instead of an array. The addresses of arr(1), arr(2), etc do not exist in the subroutine. [Code]
The variable of y1 passes to the subroutine oK, whilst arr(0) passes also like y1 into an isolated address. So VBnet interprets arr(0) like a variable rather than the first value of a long list. I haven't been able to find out why the above sample does not work. I got stuck in my programming effort, as I cannot proceed to to further development. how the code should be modified to enable the whole array information passing through the subroutine.
I'm using VB.Net 2005. I have created a Structure Array that contains 7 fields. I am trying to figure out how to sort this thing and have no idea. I've been reading up on the Array.Sort function and I'm bombarded with Overloads. I just don't know how to set up the statement. Below is my
Recently i've been developing a progam that will read in a player database that is stored in plain text if the folling format name ,age,score,date played So far i have managed to read in the file and caculate the number of players in the database by
Do Until EOF(1) aboutPlayer = LineInput(1) ' For Each line In aboutPlayer

I havent used DaniWeb for a while, so this post will be edited a few times to use the code snippit tools correctly and clean up the layout
I have this program that views the records in a structure using the previous(button1) and next(button2) buttons. The button1 which displays the previous record is already working. I have done the next button, but it didn't work.[code]it only showed the last record. I want the codes to show all of the records in the structure
I have been told that the best way to do a search in VB is to fill an array with ALL the records from a table in a database and then filter the records from the array, instead of using the SQL statement Where.

I want to create a real setup project for my application so when someone want to download it he can run only setup, not default setup that provide me VB . How can I do that?
I am using VS 2008 VB and setup my application software in Win XP without any issue. But after installed in Win 7, it doesn't work well (it show one file not found, but I saw the file in the right folder). Could it be the incompatibility of VS 2008 and Win 7? If I upgrade to VS 2010, will the issue be fixed?
I'm a Visual Basic beginner. There are many things that I didn't know about Windows software development as I've been a Mac user for 20 years and just started developing Windows programs several days ago.
Anyway, using Visual Studio Installer (File > Add > New Project > Visual Studio Installer), I have two files inside the Release folder - setup.exe and Setup.msi. I've got some information about these files. So when you publish your software, what do you do with these two files? According to one web site, you can put them together into one with IExpress, which produces a file with an extension of CAB. Another web site suggests SFX Compiler. In the meantime, I downloaded a dozen applications at Download.com earlier. If I click on the download button, the final delivery extension is .exe on most of them. I know that you won't go anywhere by double-clicking on setup.exe from the Release folder without Setup.msi. Meanwhile, Setup.msi is a tand-alone application. But nobody uses this file alone to distribute their product.
I've finally got a project compiled and tested and ready to roll out.I have discovered that the "Publish" option is not what it seems, and that we must create a separate "Setup Project" to carry out the task of installing the files.This is not the most intuitive process I've seen, and the online help on that subject is not easy to understand.I was hoping that someone could direct me to a tutorial or guide that would step me through the specific approach I need. Many of the other guides online are vague and address multiple scenarios and do not separate the approaches very well.I have the contents of my project in /bin/release. It runs nicely by iteself with no errors.Here's what I need:
1. To create a setup exe that I can distribute that will install my software, with all of the supporting (resource) files and folders. 2. I need the setup process to force the installer to "agree" to a EULA. 3. I'd would like to provide an image on the installation screen/popup. 4. I would like the software registered in the registry and rely on it being there in the registry. 5. I need it to default to program filesprojectname (it does by default)
I can retrieve records from my Database fine, but I'm having trouble updating records. I am getting a syntax error on [code] I get this error when I change the Last Name (Row 0, Column 1). [code]
I am trying to get the hang of this stupid VB.net, but it won't even let me create a subroutine or function, it use to be in the tools menu in VB6. I have spent £50 on 2 books that rabbit on about objects, property's classes etc: but tell me nothing of what I want/need to know, what a waste of money.
I hv deployed my project using "Setup and Deployment" wizard. I hv installed MS VS.NET 2003 Bootstrapper Plugin -> A plug-in for creating deployment projects in Microsoft� Visual Studio� .NET 2003 that contain the .NET Framework version 1.1 and/or Microsoft Data Access Components (MDAC) version 2.7. still it is giving the error The setup requires .NET Framework 1.1.4322. Install the .NET Framework and run the setup again. The .NET Framework can be obtained from the web. Would u like to do this now?

What is the for ... next loops in the second subroutine doing? What is the sim() array meaning?
I have a form that is bound to a table of data. I have a typical binding navigator. When I go to a different record such as next, previous, first or last I need a subroutine named "LayoutAdjust()" to execute "after" the new next record data is loaded on form. I tried calling the subroutine in the "BindingNavigatorMoveNextItem_Click" action but it executed the procedure before the next record data was loaded
Setup and deploy for my project worked fine for a while allowing you to install my program and uninstall the old version, but now it installs two entries. I don't get it, before I got it do do that it would give an error that it needed to be uninstalled first. Now like I said I get two entries in the programs uninstall window. RemovePreviousVersions = true. I change the version number and update the product code. Even tried changing the upgrade code. I just don't get why it doesn't work anymore, and its really annoying! Also, is there a way that the setup file can just be one .exe rather then a setup file and a data file?
I want to search the records from the textbox and display the records to the datagridview, if there are no records, just display empty on the datagridview.
this is not working: Dim sqlsearch As String sqlsearch = "SELECT * FROM setting WHERE mname LIKE '%" & TextBox.Text
I have this piece of code wich works perfectly when inserting records into one table using records from another table. My question is that now i need to create another table by using records from 3 other tables (tables are related). Can i use aliases on the column names, like on Oracle SqlPlus? How will be the syntax of the 'INSERT INTO SQL statement?

I am working on creating a program that records animal data (wombats) and stores it into a database, using vb.net. I am trying to add new records into a database but every time I click add, to execute that, there are duplicate records that gets added. How do i write the code so itonly adds it one time. I am using a data reader. Here is the
Problem is, I need to call a VB.NET function from javascript, no two ways around it. This is a bit harder to find.BTW -- Web/Page methods won't work. I have to be able to reference a listbox and it's selected items when the VB code-behind fires.
