Make A Function Which Takes A Number Then Does An Operation To It Again And Again Until It Gets A Vlue?
Apr 26, 2009This is probably a stupid question, but how do you make a function which takes a number then does an operation to it again and again until it gets a vlue which it already has seen, when it returns all of its values? I have this function:
Private Function fractal(d as string) As double
Fractal = Val(D) * (Val(D) - 1)
Fractal = FormatNumber (Fractal, 2)

Retain A Value From A Textbox And Add To It?
Nov 15, 2011My assignment is to create an application that allows the user to type an item's price into a single textbox, add the price to the previously entered prices, and display the total charge which includes a $15 shipping charge and a 3% sales tax.Example: I type 10 in the textbox and click calculate. the subtotal (before tax and shipping) reads $10. Next, I type 20 in the textbox and click calculate. The subtotal should now read $30.I have everything working fine except adding the different prices. I cannot figure out how to retain the value of the subtotal and add it to the next value entered.

View 2 RepliesHow To Retain Data Across Multiple Forms
Sep 8, 2010I have an vb.net windows application set up. It has multiple forms, about 6 in all. There's a main menu form, and then 5 other forms to collect data. The user will collect data on each form and bounce back and forth between forms. How do I get the forms to retain the data that has been entered into the text boxes and/or other controls on the forms? For example, they might fill out a few textboxes on a form, but then need to go to a different form and fill something out and then back to the previous form. Right now, when they come back to the form, all the data previously entered in to the text boxes is gone.

Oct 28, 2011I have a javascript function below to move from select multiple box A which is populated from database to another multiple select box B, in the event of a postback my values in B which are moved over from A got lost.

Use The Tab Key To Exit And Retain Current Cell In DataGridView?
Jan 26, 2012In my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;

Allow Labels In Disabled Panels To Retain A Their Prominent Forecolor?

Retain Executing Thread's Context During Call To QueueUserWorkItem In ASP.Net?
Nov 17, 2011We have an ASP.NET application that queues some of its long-running operations (generating reports, for example) into the ThreadPool using System.Threading.ThreadPool.QueueUserWorkItem.
We run the ASP.Net application pool using a specific domain service account so that it can access remote resources, including files and databases. When the execution starts in the ThreadPool, the user identity of the thread is set to Network Service, which doesn't allow us to access the remote resources.The web application can be accessed by users in different countries simultaneously and the format of the data that we provide to each user is based on their culture settings (using the standard globalization settings in web.config). When the queued thread is started, it has also lost this information and reverts to the default culture for the operating system.
Now, we can probably get around most of these issues by capturing the current user identity and culture in a state object and passing that to the background worker, then impersonate the user and set the culture on the thread, but this seems like a very "unclean" way to resolve this issue.[code]...
Retain Field Values On Error In A Dynamic Gridview?
Jun 7, 2011I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.
View 1 RepliesRetain Row Attributes In A DataGridView When User Sorts By A Column?
Oct 20, 2010I have a DataGridView, bound to a dataset. All the columns are sortable (.ColumnSortMode.Automatic). The user may change data in certain columns, although not the first ("key") column. When data gets changed on a row, I change the backcolor for that row (to show it as dirty). At some point, the user will do something with all of these changes.
My problem is that I still want the user to be able to resort the data by any of those columns. When it's sorted, though, I lose the backcolors that I changed. I do know which rows are dirty, this is just a cosmetic issue. Isn't there a way to retain those backcolors, or any other such row attribute?

Open File Retain The Directory Of The Last Opened File?
Jan 10, 2010So I open files and do whatever with them right. I've set the initial directory to equal the last directory, but whenever I open multiple files, it never sets the directories properly. It acts as though nothing was opened there, so it takes the previous directory as the last one. Thoughts on what's not working? Here's the code.
Code:
With FileOpenDialog1
.InitialDirectory = LastDirectory
If .ShowDialog = DialogResult.OK Then

I have multiselect enabled earlier and everything else works but this. When you open a single file, the last directory works fine. It only happens with multiselect.On another note, does anyone know why it freezes when I try to do a lot of files and use another program? I opened 700+ files to see what would happen. When I switched to a IM convo, it froze. When I left it to run, it worked.
Office Automation :: Excel Process Continues Running (.Net Framework 3.5, VS.Net 2008, .Net 2008)
Apr 15, 2011I'm calling the following method from a button click event to export a datatable to excel. After the export is completed, the excel application object is quit, released and assigned to nothing. But in reality it's not getting released and stays active unless the entire application is closed. So every time the button is clicked for export, a new excel application object keeps on running. The problem doesn't occur if two of the lines from the method below are not used. But I can't omit them as they are really needed. Check the * marked lines.
Code:

VS 2008 Visual Studio 2008 Randomly Crashing When Simply WRITING Code?
Oct 25, 2009i'm running Visual Basic 2008 Express Edition (latest service pack ... 9.0.30729.1 SP) on XP Pro SP3 with .Net Framework version 3.5 SP1 I have a rather large project I've imported from Visual Studio 2003 (Standard).The project compiles and runs just fine ... my compiled program itself never crashes.
But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.
