So I open files and do whatever with them right. I've set the initial directory to equal the last directory, but whenever I open multiple files, it never sets the directories properly. It acts as though nothing was opened there, so it takes the previous directory as the last one. Thoughts on what's not working? Here's the code.
Code:
With FileOpenDialog1
.InitialDirectory = LastDirectory
If .ShowDialog = DialogResult.OK Then

I have multiselect enabled earlier and everything else works but this. When you open a single file, the last directory works fine. It only happens with multiselect.On another note, does anyone know why it freezes when I try to do a lot of files and use another program? I opened 700+ files to see what would happen. When I switched to a IM convo, it froze. When I left it to run, it worked.

View 8 RepliesI am having issues with the Arabic language when trying to display dates and times. I seem to be unable to get the formatting to work on a date, or on a time, but it works on a date and time. Other languages seem to be fine. Any thoughts on why this is?

I'm having a slight problem getting my program to load a save file when double clicking the save file.I'm using the Command$() to get the command line argument. I can open a save file by dragging it onto the exe. But not by double clicking the save file (after it's associated with the exe).I though dragging and dropping a file on a program and double clicking the file would open it in the same way, but I guess not.So in short how does file association work and how do I get the file path set to a var when the program loads.
View 5 RepliesI have now started posting to a MySQL database created by someone else. I have no ability to change the table structure.Two questions:
1) There is a date field and a time field that loosely tracks the last edit date and time. Both are fields set up as DateTime in the database. The date field always has the proper date but the date and time portion shows as
2011-11-27 00:00:00
However, the time field shows as
1899-12-30 23:16:58.
When I am updating with the following code
strSQLCmd.Parameters.AddWithValue("@EditDate", Date.Now)
strSQLCmd.Parameters.AddWithValue("@EditTime", TimeOfDay)
The date field displays
2011-11-27 23:40:26
and the time field displays
0001-01-01 23:40:26
I'm not sure how to format the date field without time and the time field with Dec 30 1899.Question 2) I will be adding some tables and will be wanting to track date and time of first entry as well as date and time of last edit. (this may have been better posted in the Database forum, if so, sorry)
For those of you who have done this before, would you mind sharing best practises? I am wondering why would you use two fields, one for date and one for time, when the field is a date/time field to begin with. I've seen this before in another database as well. I'm just trying to work out the logic here.
