Re: Automation in VB roberto@mailinator.com10-Jul-05 22:18 roberto@mailinator.com 10-Jul-05 22:18  Right to the point. It's a VBA in Access. I could copy the files (of course they're just text) but I've got quite a lot of file and it would a pain to copy all of them manually. So I want some kind of macro to automate the proccess! Thanks. Re: Automation in VB roberto@mailinator.com12-Jul-05 23:31 roberto@mailinator.com 12-Jul-05 23:31  Well, as nobody could help me, here's the answer I found by myself. Just use this: For i = 1 To Application.VBE.ActiveVBProject.VBComponents.Count Application.VBE.ActiveVBProject.VBComponents(i).Export "file" & i & ".txt" next i This way all forms, modules, classes, etc. are saved on the local path in plain text format. Sweet and easy, uh? Hope it helps out there! Empty Date or DateTime string VOmigrant7-Jul-05 4:55 VOmigrant 7-Jul-05 4:55  In order to avoid a null DateTime field in my ACCESS database table, how do I fill it with an 'empty' Date or DateTime string? Thank you for your help in advance. Re: Empty Date or DateTime string Dave Kreskowiak7-Jul-05 5:06 Dave Kreskowiak 7-Jul-05 5:06  There's no such thing as an "Empty" date/time field in Access. It either has a valid date/time in it or it's Null. Since your database is doesn't allow Nulls, the only recourse you have is to put in a known bogus, but valid, date/time, such as Jan 1, 1970.

Re: keys is not working in datagrid Anonymous7-Jul-05 3:47 Anonymous 7-Jul-05 3:47  I may be wrong, but if you are setting the property Readonly = True, than you shouldn't be able to change the data. Perhaps a code sample or more detail of what you are trying to do? Re: keys is not working in datagrid Dave Kreskowiak7-Jul-05 4:58 Dave Kreskowiak 7-Jul-05 4:58  Of course those keys don't work. You set the ReadOnly property of the DataGrid to True! How can you expect to delete something from that which you specified can't be modified?

Re: delete row - datagrid error oakleaf7-Jul-05 7:16 oakleaf 7-Jul-05 7:16  Does anyone know of a full tutorial on the the datagrid and databinding? My datagrid still will not delete the last record without crashing. I think it has to do with the primary key of the database now though... OleDbDataAdapter1.FillSchema(ds, SchemaType.Source, "spray_log") OleDbDataAdapter1.ContinueUpdateOnError = True OleDbDataAdapter1.Fill(ds) ds.AcceptChanges() The first line is supposed to keep my autoincrement of the IDNUM working, but when I look at it (IDNUM) in my datagrid, it will sometimes go from 2348 to 2350 instead of 2349. I can see why the command builder would have a hard time.

SmartSDR7-Jul-05 3:21 SmartSDR 7-Jul-05 3:21  hi guys, I have a question, how to make a chat messenger like yahoo messenger or msn messenger and connected it with the server that use sql server ? How to make the connection between the client that use the application program (messenger) and the server that contains the sql server ? How to make this by using VB.Net ? what is the starting point (what the things that i must know to perform this)? thanks for all Re: How to make a chat messenger? Dave Kreskowiak7-Jul-05 4:54 Dave Kreskowiak 7-Jul-05 4:54  Well, knowledge of TCP/IP would help alot. How to write clients that communicate using sockets, and most of all how to write a multi-threaded socket server. Just search the articles for "CHAT" and you'll come up with a bunch of examples. I fail to see how an SQL Server figures into this, unless you're going to be logging everything everyone says.

If you're getting a message that says "This application in not a valid Win32 Application," it usually means that the .EXE file you launched is corrupted. You'll have to replace it with a new copy from a known good source. What you're saying about the problem doesn't make much sense though. Are you saying that if you replace the .EXE, then run it, it works the first time, but every time after that this message comes up? Is it possible you have a bad, or dying, hard drive? BTW: What does this have to do with VB.NET?

In 20+ years of doing this, I've never seen the problem before.
