I am filtering a Datagridview with combined help of 4 textboxes and 4 comboboxes each dedicated to a field in DB. All i know about this process is i can combine two or more filters but how do i check at a given time, whether which of these (cb & tb) have been used already to perform the filter already and then collect all the instances and perform the collective filter.

If I have the following a OrElse b and a is True then clearly b is never evaluated. But if I add an Or, then what?a OrElse b Or c
Does/should c get evaluated? And what if I put in some brackets?Apologies if this is basic. Of course I can test for the answer myself but I can't find this question answered here or elsewhere. Lots of questions dealing with Or versus OrElse but nothing dealing with Or with OrElse

View 6 RepliesI'm having problems with bindingsource. I have a proc used to update a datagridview from a bindingsource. When I run the debugger, the datatable appears to be populated rowcount is 2206 and 7 columns. When the bindingsource.datasource is set, everything looks good. The filter appears to be ok, however, when the datagridview is set to the bindingsource, it's not working. I have it in a try/catch block and an error isn't being raised. When I reference the columns to size them, an error is raised. Below is the snippet of

View 1 RepliesOK I am working on a windows service that monitors specific directories and checks to see if a file is changed. If a file is changed, it is attached to an email and sent to an admin.
The way I solve the problem...
I create a FileInfo object to do the following:
-I check to see if the file has an extension that is allowed to be attached
-I check to see if the file is under a max size to be attached
I create an Attachment object to do the following:
-attach the file to an email
I then send the email. The problem with this is when I edit the file after it is successfully attached the first time, I CANNOT save changes to that file. I get an error message saying that it is being used and cannot change it. My solution to this problem is to call the "dispose()" method of the attachment class. When i do this, I can edit the file all I want to and the first attachment works but after that the "dispose()" method always throws an exception and the file is never attached to the email when the file is edited again. Why is this happening?
Can someone take a look at my "afilter".I am getting an error when I try to read a file.Syntax error: Missing operand after 'Number' operator it works with some files but others perhaps I dont have it written correctly. [code]

I am working on an existing vb#.net 2008 windows form application that has a large number of project files in one solution. This solution can be executed many ways depending upon what the startup project is. However there is one project file that is generally the main 'startup project'. This application also has no setup and deployment currently.
What I am trying to do is to determine what exes, dll's, config files are needed to be combined together so I can deploy them? Is there certain directory paths I can use to determine what files I need? Is there some kind of a way I can test the combined files to determine what files work together so I can deploy them?
I have a number of text boxs that gather data and put it in a combined string in a rich text box that displays all of the collected data. Some of the text boxes require data pasted from other sources however when that data is then copied from the rich text box to the clipboard through a routine, it loses its formatting. home to maintain the original formating?

The issue is in the last line. ID_Part is an Int64 data type filters(0) is a string so the system returns a "Can't perform 'Like' operation on System.Int64 and System.String" error message.As you can see I tried converting the data type, but that failed since it is encased in String.Format()- it's going to be a string no matter what, I suppose.It's almost 1:00 a.m. so I'm not firing on all cylinders.

View 6 RepliesI am sitting with a situation that I have to combined (3 years) for 26 site of 29000 database files where there is 1 table in each data base called RECDATA, I need to combined all that data Into one database file called RECDATA.
For example there is a database called DB1 with a REDATA table inside it, and then DB2 with a RECDATA table inside it, DB3 with a RECDATA table inside it est. So I need to put all the Recdata into 1 Database file, or to copy all the RECDATA from all the database files to 1 RECDATA they all have the same columns All I need is to get all that data into 1 RECDATA table.
The program where this database comes from is a voicerecording system creating a new database every day. There is 1 database just for indexing (to view the recordings) and then the daily database is where the recording lies in, that Colum is called RECFILE. I will give you a example of the 2 database.
I want to add a row to that will contain dropdowns,search textboxes, and maybe other controls to allow filtering to the gridview. I've looked at This Question but it did not help me. How can I add a row so i can add these controls to my gridview?
