View 1 RepliesI have a .net 4 form application. On a button click event, I want to open a form that has a GIF image in a webbrowser control, that says please wait. Then it opens a second form that has a datagridview that is being populated from a SQL query. Then I just hide the wait form. The reason I have resorted to this method is that sometimes it takes a while to display the results from with datagridview depending on what the user selected previously. The issue that I am having is the wait form displays but the GIF does not show up. If I make the application wait by using the following code the GIF show up like it supposed to until the timer runs out. At that point the image stops moving but is still present.
Private Sub wait(ByVal interval As Integer)
Dim sw As New Stopwatch
sw.Start()
Do While sw.ElapsedMilliseconds < interval
' Allows UI to remain responsive
Application.DoEvents()
Loop
sw.Stop()
End Sub
My original intent was to use the show method to display the results form and then hide the previous form, but sometimes the previous form would close before I could display the results form.
1. Since the plate number will be stored directly into the database after being converted from the image. However, due to the conversion process of the image into text takes few seconds, it is not able to be stored into the database... May i know is there any code that can solve it? Maybe can delay the process of storing the plate number?
2. Why during running my VB, when i click on the listbox, sometimes it will immediately pop up a dialog box to ask for video source, but sometimes not? How can i solve it?
When I try and compile code in vb.net 2008 I get an error that says "value of type 'system.drawing.image' cannot be converted to integer. The error happens at piccolor.image
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _
bitmap_info, DIB_RGB_COLORS)
Here's the code that explains what piccolor.image is, it's a picturebox on form1 that has an image
readpic(Form1.PictureBox1)
Public Function readpic(ByVal picColor As PictureBox)
GetDIBits(Form1.PictureBox1.Handle,
picColor.Image , _
0, Form1.PictureBox1.Height, pixels(1, 1, 1), _

And Imports System.Runtime.InteropServices is on the top of the module, if u need more code then let me know. Also I wonder if there is a way to bitblt directly to a pixel array.
While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

I am using webbrowser control to pull html elements off a webpage from within my home made browser. The browser it's self is actually a bot. Now, I found elements for text boxes and such to login . Now I am trying to get it check the page for certain elements on every load. This way if I get logged out it will auto login. My problem is I am getting "cannot convert to boolean blah blah blah" in a line and after hours of research on msdn and google I can't fix the problem since I am noob. Heres the code. And the error resides on the line with a "arrow" next to it.
Code:

How do you navigate to a url in a webbrowser and wait for a specific time period like say 30 sec before inputting data into fields in a form? I know how to use WebBrowser1.DocumentCompleted but I don't want to use wait for the complete website to download. There are websites that don't completely download so I don't want to hang up the program.I tried using Sleep(30000) but that halts the program, it doesn't load the browser for a specific time period.

We have an application that was written in VB6 which I am trying to convert to use the latest VB (Visual Studio 2008), mostly because it's not possible to buy a licenced version of VB6 anymore (personally I'd have been happy to just keep using VB6, but without having a proper licenced version of it, we basically had to chance).The VB6 version I could simply tell it to compile the application and it produced the .exe file which I could then copy onto the server where it was running and replace the old version and then run it.
It seems like such simple things are not possible in VB 2008.I have got the application converted, and if I run it through the debugger it is working correctly, but now I need to get a compiled application to run on the server and can't seem to do it.I have tried using the publish application thing, and nothing I try succeeds in getting a working application.

View 11 RepliesOk, say I have an application that has a setting called start. and when a button is pressed on the form, it puts a day in there or something, then the button becomes disabled. then when the application is opened 2 days (48 hours) later, the button becomes enabled for use again. How could I do this?

View 5 RepliesI've made a gui for a cmd line program and I need to wait for the cmd line program to finish running before continuing.nd I have some code that starts the cmd line program and then calls a subroutine when it's finished running. But this method won't work since now I'm trying to run the cmd line program in a loop.Edit:Is there a way to just have the runtsmod subroutine (shown below) wait until the cmd line program is finished, instead of relying upon a subroutine starting when the cmd lineprogram finishes. This would simplify things greatly being able to call the sub tha starts the cmd line program and having it finish when the cmd line program is done.

I'm downloading a file asynchronously so that it doesn't stall the UI. I'm using a very basic WebClient and calling .DownloadFileAsync.The file I'm downloading is required for additional tasks after it has been downloaded. The issue that I'm running into is that, since the file is being downloaded on another thread, execution on the main thread continues while the file hasn't finished downloading.Is there any way to pause execution while the file is being downloaded? Or is there a better method?

Can i put my app in some kind of wait state for a certain key on the keyboard before continuing? But that key can be targeted to any window, not just my app. My app would be out of focus and i hit that key on the keyboard and it would act.
View 7 RepliesOK I am probably going to completely fail but I thought I would just try making an SMTP server (which came from another thread on here I was posting in earlier). At the moment I am just concentrating on RECEIVING emails via SMTP, I dont care about sending them yet.So the first thing I want to do is just make my server program be able to receive a simple HELO command from Telnet on port 25. Simple enough eh? Apparently not The problem I have is that my program starts reading the data as soon as 1 character is typed into telnet, rather than it waiting for the telnet user to press Enter before it starts to process the command. I've had a look around and looked at Athiest's examples but cant figure out how to make it wait. Here is what I have so far:

I have an app that gets info from the internet into a label, the progam then decides which event will hapen depending on the info obtained, either load next form and continue or Application.Exit

I am working on a game launcher, and I need to display a "Splash screen" until the main game has started. For this, I need to know whether or not the Process has a Main window that is fully loaded and displayed.Now I noticed the main window handle is 0 when there is none, so I tried to use that:[code]But the handle never becomes nonzero. I tried to use the title but to no avail.I do not want to go into "Thread.wait()" since then the splash would remain even if the game is already launched.
View 4 RepliesI just tried to convert some of my Projects from VB2008 to VB2010 RC, but got compiling Errors while compiling the resX Files. Seems like the reason are ImageLists/Icons, since if I remove them the files compile fine. I already tried to edit the Forms witch are showing the Errors with the Designer. The Designer changed the Content of the resX file lightly, but the error was still present Here the Error(German Version): 'FormsfrmUserTmpBUTable.resx : error RG0000: Der Objektverweis wurde nicht auf eine Objektinstanz festgelegt.' I recall a similar error in the Beta, but since I can't find it anymore, I guessed it was fixed.
