I'm trying to upload a batch of employee file but i want that when i will be prompted with a warning saying that the file employee file has conflict, i will select CANCEL and the uploading will move to the next item. what would be the best code to use for this?
Example:
Employee1 - has conlict
Employee2 - No Conflict
When i cancel uploading employee1 it will proceed with employee2.
I'm using a listbox control in a custom VB.Net batch program. Items added to the batch can have two "priority" settings (normal and high). I need to loop through all of the existing items in the listbox and make sure the high priority jobs are sent to the top of the list ahead of the normal priority items.
I'm using the following code to check the priority of each item in the list:
If batchWindow.SelectedItem.ToString().Contains("Normal") Then I'm attempting to loop through all of the items in the listbox, check the priority setting as shown. However, I can't get the loop to work and I haven't been able to find any examples of how one might do this.
For Me.k = 0 To batchWindow.Items.Count - 1
batchWindow.SetSelected(k, True)
If batchWindow.SelectedIndex.ToString().Contains("Normal") Then

Is there a statment like Exit For, except instead of exiting the loop it just moves to the next item.[code]...
Just wondering if there is a way to jump to the next item in the Items List. Im sure most will proberly be asking why not ust use the else statment, but to me wrapping the "Do Something" code seems to be less readable especcially, when there is a lot more code.

This is my thread, everything works fine. But i have a big list of proxy severs. ListView2 contains the proxy servers and ListView3 contains the ports. When a server response with nothing the proxy + port is removed from the list. But i want that if a proxy is valid that it's moved to LisView6 & 7.Now i've marked the placed where the problem occurs.
The error: Cannot add or insert the item '213.13.27.247' in more than one place. You must first remove it from its current location or clone it.Parameter name: item Removing from ListView2 & 3 goes fine but adding the same to ListView 6 & 7 goes wrong.
I need help moving a listbox item UP or DOWN. VB2010 is like 2008 so dont say that i know the 08 code, but not 2010 code. (sorry if i seem rude, i talk like this alot)
View 14 RepliesI have two (Telerik) TreeView controls, let's call them tvSource and tvDest. I want to drag/drop items from tvSource to tvDest. I have this somewhat working, but am experiencing two problems:
1) What it now does is moving the item. Instead I want them to be copied (from tvSource to tvDest), leaving the item in tvSource.
2) To allow items to be dragged from the tvSource control I have to enable DragDrop. With this enabled the user can drag/drop inside the tvSource control, which is not what I want. The items may only be dragged (copied) to an other control (tvDest).
Below is my code so far:
Private blnMouseIsDown As Boolean = False
Private Sub tvSource_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles tvSource.MouseDown

I have a listbox that when you click on the item it displays a picture in a picture box and a message in a label. It works fine when an item is manually selected, but I want forward and back buttons that will do this. It works once but it doesn't highlight the new item in the listbox, so it gets stuck. I can't use a loop either.
See code below:

Aside from one small ASP.NET webpage (using VB.NET as the language), I've been programming with Visual Basic 6.0 exclusively for the majority of my programming career (5 yrs or so).
With free versions of Visual Studio out there (Express), I've decided it's time to up my game. I also read this thread recently, which kind of killed me a little inside.
Anyway, I have two needs moving forward. I have to write a couple of small programs that load text files to a database (easy enough), so I'm going to write my next program in VB.NET. The other project is migrating a fairly substantial scheduling program that I wrote over as well. It's about 4 years old and in need of a major update so I figured a rewrite in .NET is the best way to go.
The question is, if I want to make my scheduling program web-based, am I better to use ASP.NET or the Visual Studio.NET. I noticed that it looks like you can create web apps using VS?
I have some items in a listbox and a try catch. I need it where if the program catches an error with the current listbox item to move on to the next one.

I would like to move the rectangle to the right by 1 pixel each time the timer1_tick is started. At the same time, I would like to clear out the previous boxes after making a new one. This is to make the box looks as if it is moving to the right.
I'm faced with a (fun, actually) data mining problem; I have raw ASCII files from instruments, and I want to move that data (~400 GB) into a database, then be able to run various algorithms determining correlations of time series, etc. I would like to write the mining algorithms in Visual Basic (.net, VS 2010 right now), and be able to do visualizations with VB code I have in hand.On the nature of the data: think of a set of several thousand devices, each recording a measurement at a given interval - so I'm talking time-series vectors. It's not more complex than that - though I may have vectors with holes, etc. - not sure what problems of that sort lurk in the data.I spent today re-acquainting myself with VB.NET's interface to (in one case) a Microsoft Access database. What used to be fairly simple - DAO I think it was - involved tables, recordsets, etc (and that would likely be fine). Now I seem to be required to have a weird variety of generally useless objects, e.g. 'adapters', 'datasets', etc. The problem is that I know exactly what I need, and all this extraneous stuff just gets in the way (certainly in coding complexity and opaqueness, and likely in efficiency as well). If any of these mechanisms gave me a kind of virtual access to the entire dataset, and let me control caching parameters, etc.it might be great, but I found nothing along those lines. It seems like useless bloat, though I suppose it must be useful to someone.Anyway, I tried a number of different approaches, and none seemed at all aimed at what I need to do: efficiently do math on a large dataset. I can't believe I'm the first to have this problem, but I can find no useful wisdom out there. I'd be comfortable with pretty much any underlying database mechanism: MySQL, SQL Server, MS Access, but ideally something generally SQL based (I may eventually have to transition this entire system to draw from a client's SQL database, though that's not an overriding concern now). Other than that I want simplicity and efficiency. I thought my old ODBC techniques would work, and to some extent they do, though modifying tables seemed to have bizarre problems (no errors, but not modifications either).
I do have a fairly aggressive deadline to show some algorithm results, so my focus in the short term is to get something reasonable working *in* the short term - in other words, it's less important to me to pick the 'fastest' relational database than it is to pick a database that lets me focus on coding the algorithms, not working through tedious data access coding. If this db could be any smaller, I'd have tried to do it all 'in memory' at least for proving concepts; I don't want to have to learn an entire jargon and approach just to be able to retrieve data points.Perhaps I'll need to bite the bullet and just write something myself, a .dll perhaps just to save and restore large time series vectors. It seems a bit frightening to me that one would have to do this in this age, what with all the database systems out there, but I don't have much time to work through arcane interface logic.

I have an app that I have made. The application generates 14million combinations of numbers and inserts them into an Access Database. As you can imagine, this takes AGES (whole night) to compute. Is it possible to make the same method call twice so instead of one combination being generated and inserted, two or more are?
View 5 RepliesI have a MenuStrip with several items in it. All I am trying to do is select(check) only one item at a time.
Example: Lets say I have a menu title Fruits, and under the menu are several fruits.
Currently, when I click on one fruit there is a check mark, good! The problem is when I click on another fruit there is also a check mark and so on. I only need the menu to check one item at a time, this will unchecked an item if I check another menu item. I tried using if statements but doesn't even come close to working. Any ideas on this?

What I to do is really simple. I want to add a group of text boxes in my VB net application. note that the number of text box only can be known at run time.
I want to give default value to this group of text boxes. At run time, users can input text and change the text for each item.
How can I do this? Is there a control to do this?
What I can remember is ComboBox control. However, I only can display the item text and do not know how to change the text for each item.
I have a datatable which loads data from an Excel Spreadsheet. One of the columns in the Excel SpreadSheet was of type "Date/Time" in which date values are stored. Now I appended the datatable with three new rows and I wanted to store string values in these rows using the code below. However due to the fact that one of the columns are date/time type, an error is generated as date/time column does not accept string value. I have two questions
a. Is it possible to store string value in date/time DataColumn?
b. Is there a remedy to this situation? [code]
Just want to ask this. I have a jQuery that move listbox item to another listbox. An its working fine the item was remove. Sample: I remove item in listbox A and it was added to listbox B. But here is now the problem, when I tried to check each item in listbox A, I noticed that all items that was removed was still there. But i can see in my eyes that it was removed. but when I tried to run a code to check each items - all item that was removed was still there.
