VB Spread Sheet Writing Lock
Jun 13, 2012at the moment I have a small application and need to take information from an object and display it into an excel file, using the Microsoft.office.interop class I've been able to write to the file, and it shows one by one the records being added, however about once every 3 times I try it, the spreadsheet stops filling somewhere between the 300th and 600th record, I have 6,000 in total and it's not breaking every time, I put a check after it finishes to see whether the last record is filled in but the code never reaches that point and I'm unsure of what's happening I also don't know how to debug the problem as it'd mean going through 6,000 loops to check for it stopping... which might not even happen?

.Net 2008 : Multicolumn Combobox Like Access?
Jul 17, 2009I am running VS2008 and developing a Windows Form App in VB.Net. Is there not a bound multicolumn combobox like Access has had forever? If there is one buried in VS2008, the Windows OS or MPF 2010 or somewhere else would you mind sharing? I could hardly believe my eyes when I did not see one in the common controls list.
Not knowing the correct terminology, I would like this control to be a tool component that I can drag onto my form and set the binding and column properties and be done with it.Come on Microsoft VB.Net Dev Team... where have you been on this? This type of control has been out for umpteen years in Access and 3rd party took kits. There is nothing that says Rapid development like roll your own code! I have seen serveral articles on how it can coded;?

View 2 RepliesVS 2005 Displaying Multicolumn Data - Which Control?
Jul 17, 2009I would like to create a multicolumn list of items, similar to the right pane of the Windows Explorer window. There are rows, one for each item. And there are columns similar to the filename, size, date of last modification, etc. columns of Windows Explorer. The data supplied to the control will be individually extracted from files.

IF Works But Loop Required - Huge Network With 20+ File Servers All With Data Spread Out Across Them
Mar 4, 2011My app is a fairly simple and im sure with the right knowledge this would take 2 minutes.. but sadly iv been at it for hours. So my scenario here is a huge network with 20+ file servers all with data spread out across them it can take hours to find the folder required.
Hence this app.. so it consist of a input box, progress bar and a button, using FileSystemObject I plan to interrogate a directory to see if a folder exists (folder specified by user input) however it need to check multiple directories, in my old app I used a list box which wrote to a text file allowing the user to add additional directories then using if statements proceeded through the servers.. however they have added that much that my IF's have ran out really because i know it should have been a loop
