how to cause it so that my program will not proceed while a web page is loading. For example, if I use this:
webbrowser1.navigate(www.amazon.com")
sometimes it will have finished loading the webpage before the program proceeds. Other times, even if it says it is done, it is not done and it causes my program to crash.
how I can cause my program to stop and wait until it is sure the webbrowser has completed loading?
I've made a tabbed web browser and I'm using
CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Stop()
instead of WebBrowser1.Stop() for navigating.
but I want to know when a web page has finished loading?
Normally the following works, but not with tabs
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
End Sub
Is their a syntax to tell if the webbrowser has finished loading?

View 6 RepliesI typically write my own servers, javascript, etc in vi. I've been given a project to enhance a VB.Net / ASP.Net application and I'm having some troubles figuring out how to get the user control to render BEFORE the page finishes loading.When I use normal browser as the viewer, everything works OK. When I try to use generate the page as a report, the report generator spits out the PDF while my JavaScript graph drawing stuff is still in it's initialize functions.They are using EvoPDF as the PDF generator. It appears the page is being considered complete after the page is loaded but before the javascript is executed.I admit I'm a bit lost when it comes to ASP.NET, but I know HTML/HTTP/JavaScript very well.How can I force the page load to wait until my usercontrol finishes rendering?

Well I know this could work for a browser with no tabs:

But the thing is, I do have a tabbed browser. I tried this code, But it didn't work.

View 8 RepliesI have an application that allows the user to upload information from and Excel sheet. Since the user is more familiar with Excel, they prefer to do it this way. My software will close the workbook with Me.exApp.Workbooks.Close() , but if you have the task manager running, you can see the Excel application continues. I know the workbook is closed, b/c it asks if you would like to save changes. One instance of Excel will close when the program is exited, but the user normally builds a folder of Excel files and does them all at once. If 8 instances of Excel exist, only one will close with the program.

View 5 RepliesI have a piece of my code that uses a for each to loop a certain amount of times depending on how many saved fields there are in an xml.
vb.net
'// Write an .html file ready for debugging
If (File.Exists("Working/" & textBoxCampaignName.Text & ".html")) Then
'// Do nothing the file exists

So the for each loops depending on how many nodes it finds in the ("/campaign/secondarySection") this works great, it loops accordingly, what i'm trying to figure out is a way for a messagebox to show once the loops are finished, i can't think of a way to find out once the loops are done.
I'd like to know... well, I have finished a project managing databases and all that stuff... and using ADO.NET, some databases and the main program, I'd like to compile it all to make an installation and use those databases.If I use the exex that is inside the debug folder... in other computers gives error and don't show the content of the databases. What I want is just the exe but with the databases visible in the other cpus, how to install the app in any windows computer and what I need to know or give is:
If I have my installator and I give this to a friend, he can use the databases ? He need the SQL 2005 Management to see that content of the databases ? Or I can just give him the program and work with the databases??

View 4 RepliesI have recently developed and finished a software in which works like aim.But here's the problem, the server worked just fine for local friends because they lived only 25 miles from the server, so it was lag-less.But when uploaded to a web host, it lags every time it pings the server.The server is in PHP, so there's no need to buy a dedicated computer for 400$/month more.Here's the function in which the client constantly calls upon:

I was thinking about recoding the getpage function so that it would connect to a TCP server and constantly wait for new messages which I am still not sure if this might cause a lag if the host is in the US and the client is not(for example). provide me a remedy to this problem?

View 3 RepliesI built a program in visual studio 2005 that access a Microsoft Access database. I need this program to be a standalone program on many machines. To do this, I need to install a copy of the database when the program installs.

It still tries to point to the folder it is in on the comnputer i built the program.
View 11 RepliesHow to make a button to show up once/while typing something on textbox is finished.
Say that you are typing something on a textboxes and once you finished them, a button will suddenly shows up.
If anyone knows how to do this stuff, please post some sample codes and explain it for me in a brilliant way.
I am making a program and I would like it so when the progress bar finishes it open form2. Here is my code:
Public Class Form1
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
ProgressBar1.Increment(1)
If ProgressBar1.Value = ProgressBar1.Maximum Then
End If
Would I make it, like progressbar1 makes it to maximum form2.show()
When a button is clicked,my program gets the list of all Drives on a current computer.Then I use String.Concat to merge the drive letter and the rest of the path.So I get something like: "C:" + "somefoldersomefile.some_extension"That creates a full path to a file I am looking for.Then I check if that file exists.If it doesn't exist,I use Process.Start to run the setup file(to install the program I need).It works well and installs the program I need.I want my application,after the installation is finished,to check again if the program is installed and ofcourse confirm that it is.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim DriveList As String() = Directory.GetLogicalDrives()
