I'm not talking about VBA, I need to "work" with them from within my program not from within word or excel.

View 3 RepliesIve got an app that holds a list of site we have, At each site there are a few devices. The idea is when they click on a site all the details for the site are loaded and then a second thread sits and pings each device to see if its live. Im trying to do this in a seperate thread so if they click another site while its still pinging them it doesn't wait before it switches site. This all seems to be workling fine except if you click through the sites quickly, when you do that it will eventually come up with
Quote:
{"Collection was modified; enumeration operation might not execute."}
The error flags up on the "Next" line in "ThreadedPing"

Public Sub ThreadedPing(ByVal dt As DataTable)

I want to do this becuase the site i use goes down alot so when i changed the update url no one was able to download the update for the new update server.
View 16 RepliesI'm deploying a VB.Net app (VS 2010 Pro) that requiers the user click a command button to open IE to a financial WEB site and download informaion from the site. The app works fine in every detail when installed on the development computer. But, on the target computer when the command button is clicked an unhandled exception occurs which says: System.IO. FileNotFoundException:File Not found.My code behind the button is Shell("C:Program Files (x86)Internet Exploreriexplore.exe www,fidelity.com",AppWinStyle.NormalFocus)
This works fine on the development computer. Do I need a way to code this as a relative path? If so,can you tell me how this is done?Throughout the app I have written relative paths to needed files using paths like (Open(Environment. GEtFolderPath (Environment. SpecialFoldder.Desktop) + "File Name). They all work fine when deployed.
I'm being asked to maintain several internal-only web apps for my company. For testing, after making my changes, I've created some staging sites which make use of separate databases. As such, if my users were to mistakenly use this site as if it were the production site, they may enter important data and wonder where it "disappeared" to thinking it was the production server.
I'd like to create a big banner of some sort across the top of the staging site (which ONLY appears on the staging site) to remind my users that they are on the test site. I'd like recommendations on the best way to do this, with the following considerations:
IDE: Visual Studio 2008
Server: Windows 2003 with IIS 6
Language: VB.NET 2.0
i want to know how can i code my button when i click it will open my site ... i Think i was clear.

View 1 RepliesIn VB6 I load a recordset containg all of the records (6 fields per record)in a table into an XArray and then manipulate the records in the array and then write them back to the original table. The array issorted by the first field (1 to maybe 8000 or more) I need to find records in the array by an ID field and then move them (because of some external criteria that happens many times) from say number 400 to number 375. Then all of the other records between 375 and 399 were renumbered up 1 to fill the gaps left by the move.
The XArray worked well as it could find and also move to a next record easily to facilitate the revisions to each record quickly. Everything is done in VB6 in code and nothing visual needs to be shown to the user until say 2000 of these external changes are complete. What is the best, most efficient way to do this in the .Net framework in VB2010. Datasets, Dataviews. tableadapters, arrays. enums ?
My assignment is to have a user enter in big integers using what i think is two parallel arrays. I got this far but now im stuck. I think i need to actually convert the text box input into an array but i do not know how to do that. I am all over the place in this project.

I have a VB.net console app and I am opening a function in a dll written in fortran. I am passing 3 arrays through the function by reference. When they come back out the otherside they ahve all tunred to arrays of only one element And that element is 0.I read on the internet somewhere that when doing this kind of thing it is a good idea to only pass the first element of the array into the function.I tried changing my function declaration to accepting single elements rather than single dimensional arrays, and now the arrays are the same length before and after the function call, but they don't seem to be changing at all, so i'm not sure that this is working
View 1 Repliesthe statement Dim state(49) As String and maintain a list of certain states. The list of states should always be in alphabetical order and occupy consecutive elements of the array. The buttons in the program should give the user the following options: (a) Take the state specified by the user in a text box and insert it into its proper position in the array. If the state is already in the array, so report. (b) Take the state specified by the user in a text box and delete it from the array. If the state is not in the array, so report. (c) Display the states in the array. "

I was wondering if anyone knows a built in method ( LINQ say or a LAMBDA expression or other way ) that you can compare2 arrays - collections that would be valid for an equivalent 3rd array - collection which is a combination of the 1st two.
As an example consider;

View 7 RepliesI realize that this would mean a third-party component and I've looked at a few. Does anyone use/know of a component that they would recommend to get reliable, quality Word to PDF conversion via a VB.NET application?
Anyone know of any cheaper options that will do a good job? I tried a couple of cheaper RTF to PDF convertors, saving the Word doc as RTF via the app but the PDF they output lost formatting on Word tabs, table of contents, page numbers, etc. Not good enough.
Otherwise, I will have to tell the app users they will need to convert the Word doc to PDF themselves (unless they have Word 2007 and pdf add-in which I can probably offer as an option).
