I'm fairly new to programming and have little to no experience with sql and file transfers. Here's what I'm trying to do:
1. Link my program to a database containing images (or pathnames to images)
2. Allow user to select a starting image and ending image (max 50) based on image numbers (which they already know)
3. Collect selected images from DB or could just be a copy of the image.
4. Export images to a new folder so that my other program can process and OCR them
I have the form built, but I just can't figure this out.

View 4 RepliesI am reading a file and loading the records read to a database. At the end of this process there needs to be a check that the counts match. This code was already written and the comment doesn't give me great confidence in it: ' Description: Get the number of lines in the record file. Thisshould give a good indicator of the number of recordsIt should or it will, using this code?:
Dim i As Integer = -1
Dim line As String = ""
Dim sr1 As StreamReader
[code]....
Then i is returned as the count of records in the file. Is this the best way and is it reliable? Records in the file are delimited with a newline

View 4 RepliesI see so many programs take command-line arguments with flags, for example gcc hello.c -o hello. Of course, I can implement that in my application:
Dim args() As String = Environment.GetCommandLineArgs()
Dim oi As Integer = Array.IndexOf("-o", args)
If oi > -1 AndAlso oi < args.Length Then
CompileTo(args(oi + 1)) 'Or whatever
Else
CompileTo("out.exe") 'Or whatever
End If

Does anyone know of a reliable way to cancel the ItemCheck event on a CheckedListBox? I am in a situation where the ItemCheck event should basically discard changes on a form, however, if the person decides to cancel the discard I would like the ItemCheck event not to fire so as not to change anything.
View 2 RepliesI eyed VB.NET 2010 Express and created the damn app. It's up and running and it does what it's supposed to do (in v1). Now I'd like to distribute it for free while:
(1). Have a reliable way of knowing (and everybody can check this out) the number of downloads.
(2). The app cannot be passed from one user to another, but has to be downloaded from the reputable biz (there can be more than one biz) that accurately provides the number of downloads.
(3). I can have total control over the app (once it's downloaded by the users), that is if I want to inform the users of updates or whatever, or if I want to add some ad windows to the form I can do it whenever I want and how I please.
How do I do (1) to (3)? What am I supposed to read to do (3)? ADO.NET and ASP.NET? Any shortcut? What's the easiest way of doing it? I'm not sure I'm looking for a career in programming, for now I just want to take this app off my shoulders and go back to daydreaming.

View 7 RepliesI was using ContentType="application/vnd.ms-excel" on my web site to display a datatable in an excel workbook on the client. It worked great. Now that I have upgraded to Office 2007 and vb.net 2010, I get a warning saying that the file is in a different format than specified by the file extension (.xls). I googled new ways of exporting data to excel, but have yet to find a good example. I usedMicrosoft.Office.Interop.Excel which worked great, except I read that you are not supposed to use this on a web server.
View 1 RepliesWe have a VB.NET program that needs to periodically call a function in an external, unmanaged DLL to communicate with our legacy application. We are having a problem with the application (seemingly) randomly not being able to find the DLL with the unmanaged code. Currently we use DECLARE FUNCTION blah LIB for the unmanaged code. Would it be better/more reliable to use DllImportAttribute instead? Or am I missing something else?

View 2 RepliesI am developing an application in which data will be handled offline and then fed back into the main application. Hence need the facility of Export & Import of data.I am using WriteXML to export desired data from the server database using dataset.
The data is imported back, into the Client module. During the day client may modify/insert records in the imported data. At the end of day, the client exports back the modified data and which needs to be imported back into the system's main database.Now what I want is, if new record is entered by the client then it should be inserted into the dataSet and if original record is modified during offline mode then the Original data should be updated with the new value. I think, its similar to the DataSet and Database concept i.e when dataSet is updated. But am not able to do this.
At present, if I import then all data is imported irrespective of whether the data already exist or not.And if I implement Primary Key in the dataset then for modified data it gets stuck with constraint.
