Capture Url When IE Exits?
Aug 5, 2010
I want to allow my user to add urls to a database, much as a user might add file names. I have a form with a label, a textbox, and a browse button. I would like the browse button to load the user's default browser and then have the final url appear in the textbox when the browser closes. I have not been able to do that, but I have come close. I have not found a way to capture the url from an arbitray browser, so I instead load ie.exe and then capture the url with an OnQuit handler. That works (even verified by the debugger) but I am unable to get the url to appear in the textbox without actually clicking in the textbox once ie closes. I would like a suggestion as to how to avoid making my user click in the textbox and, if possible, to load the user's default browser and still capture the url. Here is my code for the Browse button (IE is defined at the class level as Dim WithEvents IE As SHDocVw.InternetExplorer):
theURL = ""
IE = New SHDocVw.InternetExplorer
AddHandler IE.OnQuit, AddressOf HandleIEQuit

I am using VB.net and Sql server 2005.
I have GridView in Application where I have my CPUserID. There can be thousands records in GridView with different CPUserIDs.
Now I have a button "Allocate Token". But before allocating the token I want to check in my Token Table that if that CPUserID has already exists in table it should not allow user to allocate token and will return some message for that user.
For Each curRow As GridViewRow In GridView1.Rows
Dim cpuserid As Label = CType(curRow.Cells(1).FindControl("lblCPUserID"), Label)
Next

I have been using the 'findby' method for sometime, but now it suddenly is failing me on a new data source I have added to the project. I have the data source bound to a form and I am trying to find values based upon a primary key. This evades me, I am able to look up rows using 'findby' with other tables, but not this one.
Dim AnsiX12Row As ansisupplementDataSet.ANSIX12Row = Me.AnsisupplementDataSet.ANSIX12.FindBySegmentElement(CurColName)
If AnsiX12Row IsNot Nothing Then
[Code].....
I have checked and re-checked, the CurColName is for a value in the table, but cant seem to find it... I always have AnsiX12Row = nothingBradford W Brown

I have just converting my VB6 project to VB.NET 2008. I have set up start with Model. It start with Main() sub, in Main sub I have declare as below:
Dim frm as new Formpwd

In formpwd I have UserId, PWD as test box and Two command buttons. The system executes form_load code and then PWD and UserId_Gotfoucus handler and then closes the system. Why is not waiting to accept UserId and PWD?

Im working on a silverlight application where a user can create, edit, delete objects. The changes they make are placed in a queue which is processed every 4 minutes. When it is processed, the updates are sent over an async web method call to be saved in a sql database, one at a time. When the first update finishes, the next starts.Im having a problem when a user makes a change and then exits the browser app before the 4 minute timer has expired.Currently the changes are getting lost.Ive built on what the guy working on this before me has done, and explored the Dispose and Finalize methods, trying to start the update process when the factory is being shut down, but that isnt working due to the async nature of the web service calls. I get errors saying needed objects have already been disposed of.

I had originally saved the project I was working on to my desktop, but now I have moved the folder to another location on my hard drive (didn't want it on my desktop anymore).
But since I've moved it I get the message:
The working directory does not exist: 'C:old folder locationResources'.
Is there a simple way to update my project to the new folder location?

I'm running a bunch of automated tasks in a thread I'm creating via the Thread class. So I'm not using a BackgroundWorker.
During parts of the automation, the thread may exit. This is normal. But when the thread completes, I need to finish up some additional tasks. I can anticipate all of the conditions in which the thread closes, but I'd rather not to do the final tasks at each point, as this will create a lot of redundant code.
So instead, I wanted to write an event that is triggered when the thread exits. I looked through the Thread class, but all I could find was the ThreadState property, which has a Stopped property. But, when I try to add a handler to that property, it doesn't allow me.

I'm designing a Windows Forms Application, and there is a dialog that should NOT exit when the enter key is pressed, instead it has to validate data first, in case enter was pressed after changing the text of a ComboBox. I've tried by telling it what to do on KeyPress event of the ComboBox if e is the Enter key:
[Code]...
But no success so far. When the Enter key is pressed, even with the ComboBox on focus, the whole dialog is closed, returning to the previous form. The validation is NOT done at all, and it has to be done before exiting. In fact, I don't even want to exit on the form's enter KeyPress, the only purpose of the enter key on the whole dialog is to validate the ComboBox (but only when in focus, for the sake of an intuitive UI). I've also tried appending the validation to the KeyPress event of the whole dialog's form, if the key is Enter. NO SUCCESS! It's like my code wasn't there at all.

What is the best method to do data validation? I want to do data validation when the user exits a control so that he gets immediate feedback. I can use the Validating event or the Leave event for that. The problem is, that if the user doesn't know the right answer, and just wants to click the cancel button and leave the form completely, it won't let him. It continues to give him an error message until he completely deletes his answer. Very frustrating. Does anyone have a good method for doing this?

Windows Forms VB Application.. I added a splashScreen to my application. And it was flashing only for a second then going away so I added a sleep timer to my Form Load event... The problem is now the splashScreen stays open even After Application exits, instead of simply closing at the end of the sleeptimer.. The Part of the Form Load event that is causing this is as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Threading.Thread.Sleep(5000)

I copied a project I wrote on my XP machine to my other computer with Windows 7 64-bit. When I run it through VS2008 it exits immediately. It does not run a single line of code. The exit code is 0. I need to post what else it says. But I did find a posting about this saying the path to the temp files may be wrong for it but he did not know how to change this. If I create a new peoject and put a command button on it, the program runs. So I was wondering if it is something like the temp files or something else. The machine runs a compiled .exe of the program from the XP machone when installed on the Windows 7 machine. So I do not think it is the program not being compatible.

I'm currently having an issue with VB.Net and Adobe Acrobat. The issue comes from exiting Acrobat but the Windows Taskbar still states that there is an Acrobat.exe process open. I have tried using Marshal.ReleaseComObject(), but it still hangs there. I do not want to have to rely on the "End Process" option on the Task bar in order to remove it.
Below is a snippet of the code that I am try to using:
Try
'Tries To Close Acrobat Application
acrobatApp.Exit()
System.Runtime.InteropServices.Marshal.ReleaseComObject(javaScriptObj)
[Code] .....
Although I am not sure if this could be a problem - I run a javascript saveAs script on the Acrobat side in order to make a copy of the file. This also could be a reason why it is hanging, but I ruled it out based on basic knowledge of saving files and exiting from other Acrobat/Microsoft Programs. Acrobat only closes when my application ends. (Currently) I am trying to make it consider the case if a user manually closes the Acrobat application.

i'm using the AppendText(serialPort.ReadExisting) method of the SerialPort class. i'm sending to the serial port a 12 byte frame. however in the TextBox control streams printed seem choppy as if the ReadExisting method is exiting too quick to grab all 12 bytes so i can display them at once.

So I am hacking together an app which listens to traffic using SharpPcap library, it reconstructs the packets from sessions using the code from TpcRcon.
Listening and reconstructing part work on their own . What I want is on each packet arrival main window gets an event so it can display the packet , and when session is reconstructed display a complete packet (I am interested in HTTP ones) . -That is where it breaks with weird symptoms: for example right now it does not stop on invoking stop listening method - the sharppcap library function hangs there forever waiting on this line of code : m_pcapThreadEvent.WaitOne();//wait for the 'stopped' signal from thread
I also had it not working and crashing in sharppcap function because I had omitted one parameter in form delegate- which makes no sense, because form delegate does not deal with packet capture at all and only reacts on "New Packet" event from my "Listener" class (which is only there to notify main form)
My app starts as module main instancing class "Listener". MainForm has it
registered as friend with event and handles even "New Packet"
Main Form:
Private Sub uiListenStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btListenStart.Click
aLogger.AddMessage("Started Listening")

Ok so this is going to take some explaining. The process I am trying to do is grab data from a table function in SQL and then fill a dataset with the returned values. I then have to run this query twice more to query an alternative number table. Then add to the same table as the previous queries.This needs to be as fast as possible, so I am currently using an adapter.fill to populate the datasets and then a dataset.merge to put them all into one table.
The problem is the query can return duplicates which waste time and space, because of this I made column 3(part_ID) the primary key to stop duplicates.When this is run with the .merge it quits at the first instance of a duplication and doesn't continue with the population.

I want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.

I have a string with value ""123|abc|456|" separated by vertical bar. I want to create a sub that reads upto "|" and then exits the sub.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim myString As String = "123|abc|456|"
For Each character In myString

My output looks like this 123abc456, which is not what I am looking for. How do you do this with Do While, and stop the loop when it encounters the vertical bar "|"?

I want to capture Form1 window, not what is on top (what I actually see).
Dim screenshot As System.Drawing.Bitmap
Dim graph As Graphics

It captures what is on top, for example: I have firefox on top, so in myPic.bmp will by firefox, not Form1 window. So, how can I do that when some programs are on top, it captured Form1 window?

Searching found many answers along the lines of it depends on the device driver", but I don't think that it's that way here.
I have a cheap & nasty RFID tag reader. You just have to open notepad, touch a tag to the read and its serial number appears in notepad (I have not tried it in Linux).
Anyhoo, how can I programatically capture this serial number in VB.net (20088 express)?
