this is urgent. i have a form in which i need to give timedelay of 3 seconds before each line executes. But when i try system.threading.thread.sleep its freezing the UI and furthermore all delays are executing as one single delay. that is
[Code]...
how do I delay my program without freezing? I am sure there is another way to do this without timer.PHP uses sleep(). What do VB use?I tried some Delay or Sleep function but don't seem to work..

View 9 Repliesim looking for a way to have my program wait a certain amount of seconds before it goes on to the next command, ive tried the sleep command but that freezes up my program and i cannot let that happen, ive heard of using timers as a delay but i don't really know how to do that.
View 4 RepliesI know that time delays have been covered before around almost everywhere. however a method that forgoes forcing the GUI to become temporarily non-responsive, is all but a myth, or at least to my findings. i have the need for a GUI program to delay before the next command, however using the current method, detailed following, it causes the desired effect however it dose make it much less polished as when you click anything else on the GUI it goes un-responsive for the directed time. [Code] make a sub called say Tdelay( milseconds as integer) and have it run a loop as many times as the milseconds variable indicates and each time making the thread delay for 1 milsecond and then update the GUI/form in some way, then re-loop.

View 17 RepliesWhat line of code would I need to use the timer function just as a delay, so like as lines are being executed, once it gets to this timer it waits for say 1500 milliseconds before execution is continued.

View 3 RepliesI was asked to create a slide show in Visual Basic 2010 that had to meet certain requirements but I've run into a few difficulties. I have a slide show that works but it doesn't meet my friends standard and I'm not sure how to go about this process.He asked me to meet these requirements: The Slide Show Project requirements of your project are:
1. The use of if statements.
2. The use of arrays.
3. The use of loops.
4. The use of graphics.
5. The use of key/mouse controls.
6. The use of images.
7. Allow user to set delay time for each photo.
8. Transition effects 1: Fade in, fade out
9. Transition effects 2: Fly in, Fly out
10. The use of timers.
11. Borderless, always centered.
12. Introduction Screen, Credit Screen.
13. innovations, special feature.
The code that I had previously came up with was as follows:
Public Class Form1
Private ImageFileNames As New List(Of String)
Private CurrentImage As Integer = -1[code].....
I pre-loaded my own photos into the slide show but I just want to know how to right this code in order to satisfy my friend.

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.

This is in ASP.net 4.0 VB using Microsoft SQL Server.[code]
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

I'm trying to find where this code might be leaving old connections open, and I found this code that might be the cullprit. It is in a function. I'm wondering if this connection would close, if an exception occured from within the USING statement?

I'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.

View 3 Repliesi am having trouble getting this to parse and remove the html and only leave the flash applet here is my code so far:
WebBrowser1.Document.Body.InnerHtml = WebBrowser1.Document.All.Item("object").OuterHtml
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.
