Using a timer, am making a rectangle platform move from left to right. The problem is that it leaves a trail of itself and I believe this is down to refreshing or something. here is the timer code if your interested:
If shaperet = False Then
Timer2.Start()
platform.Left -= 4

View 16 RepliesI was hoping that the various controls for WinForms in VB.Net 2008 would have a property such as OldValue and NewValue that I could pull from the Change property.
I'm wanting to write a generic code that will save the OldValue, NewValue, name of field and name of table, and date of change directly to a simple Audit table.
Items aren't changed often, but we need to be able to trace the history of changes to certain fields. I've got the code written for saving to the table, but I'm not finding anything that will show me the two values I need.
I get the NewValue from the changed property but how can I locate the OldValue for date/time pickers, text boxes, check boxes are the main items on the forms.

I'm trying to create a 'trial version' for a software of mine, currently it is pay-only. Basically the most efficient way I can think of is to simply change the startup form of the trial version after 15 days. The new startup form will simply be a request to register.
-How can I change the startup form after 15 days?
-How can I ensure that this cannot be changed afterwards (so it isn't easily pirated).

When a user leaves a TextBox on the form I execute a format and save to a variable. This is saved to a database by clicking on a ToolStrip button.
The problem occurs if the user moves the mouse directly from the TextBox to the Button. Neither the Leave event or the Lost Focus event is triggered, the variable is not created and, of course not saved.
If I put the code in the Save Button and the User moves to another control, the formatting(data type Double to currency format in the TextBox) that I want to show is not executed.

I have a modal pop up that is supposed to upload documents. It does that just fine, except that it doesn't give them a title, therefore nothing shows up on my page since Title is how they show up in the list.

View 1 RepliesI find that if I do me.close and then reopen the form with showDialog later, things are as they were before I closed it. If I use me.dispose and then later open the form again, its as if it was never opened before. Are these two both valid methods for leaving a form?

I'm trying to update an old code that I don't have the source code for. In this code, the user enters an integer in a textbox as part of a form. Once they move to the next textbox a new form opens to input the number of files that the user chose (in the textbox).I have created all of the forms, but I can't figure out how to get the code to open the new form once the integer has been entered in the textbox and the cursor has moved to the next textbox. I would prefer this to happen automatically and not involve a button.
View 13 RepliesI am experiencing a strange issue with a VB6 -> VB.Net conversion. There is a function that uses ADOX to look through the tables in a given database, and reset the seed values of any columns in said tables with the auto increment property set to true.I tracked the issue down to a call of "col.Properties("Autoincrement").Value". If this line of code is commented out, then the file handle properly terminates when I close both the ADO and the ADOX connections at the end of the function. If I leave that line in, the handle stays open despite the closing calls and forcing garbage collection.Here's how I am closing the objects:
System.Runtime.InteropServices.Marshal.ReleaseComObject(adoConn)
Dim connection As ADODB.Connection = cat.ActiveConnection
If Not connection Is Nothing Then

View 4 RepliesI'm looking for a way to process the text entered into a textbox, before the the focus is lost from the control. Or a way to pass a reference to the control to a function/sub when the control has lost focus. In Access I would be able to use the AfterUpdate event. I have tried the following events, but have not figured out how to get what I want from either of these events:
- TextChanged (tried to capture the Tab key, didn't work)
- Validating (when fired for Text1, the ActiveControl name is Text2 which is the next TextBox control)
I have a situation like this:
if <some test> then
do lots of stuff
endif
I'm refactoring the code getting ready for some major work. I want to remove the if/endif pair but leave the contents (do lots of stuff) intact and in place.

Our program works fine, until someone locks the computer or the screen-saver pops up (but not ctrl+alt+delete). Once the computer is unlocked/the screen saver is closed, the application stops drawing everything except the title bar, and stops responding to input - it displays a mostly-white window which can't be moved or closed.(Example of application freezing - the mountains are from my desktop background)If we let it sit for about 5~10 minutes, it comes back to life, and doesn't hang again (even after locking the computer/screen saver popup) until the application is restarted.
