I'm automating a download,and I know the URL to the download page. Well, not exactly. This URL is indeed what I need to use, but the website redirects it to the REAL download page. Unfortunately the redirect only happens if I do an exit sub. That is to say, if I do a loop sleeping one second per iteration, the loop goes on forever waiting for the redirect. But if I branch out of the loop by inserting an Exit Sub in break mode, I can see the redirect occur onscreen. (I can watch the current page in the web browser transition to the desired download page). The trouble of course is that I don't WANT to do an Exit Sub at that point, so what's the solution? Do I need to call Browser.Navigate on a background thread?
I am working with vb.net to making a form that prevents the web broswer on windows internet explorer from navigating to certian pages. The code can't just work on internet explorer because I could make a program with a web browser that navigates. It has to prevent the web browser itself from navigating.
I am currently building a webbrowser that only loads one page, but I don't want the user to be able to navigate away by clicking advertisement links, as I don't want them to be able to surf the net, clicking links could eventually lead them back to Google to search for what they like if they are clever enough!
I have this code set up to navigate to a certain .html document depending on what's selected from a ListBox:
Private Sub FileList_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles FileList.SelectedIndexChanged HelpWindow.Navigate(System.AppDomain.CurrentDomain.BaseDirectory & "help" & fileArray(FileList.SelectedIndex, 1)) End Sub
The problem is, when I first select something in the ListBox, it successfully navigates to that file and displays it. But when I select something a second time it doesn't change.
All of the paths it's trying to navigate to are correct. I've checked this 1000 times.
I've got a webbrowser. It's prettey advanced, given that I've spent quite a lot of time coding it, and here is my code which will get the Favicon of the current website when a the webbrowser has finished navigating:
Sometimes, a user has switched tabs before the webbrowser has finished navigating. So my question is: Is there any way in which I can determine what tab the favicon belongs to and set it to that tab, rather than just setting the favicon to the selected tab?
Here is my code: Dim TestHeader As String = "Referer: [URL]" If chkRefferer.Checked = True Then WebBrowser1.Navigate(cmbUrl.Text, False, Nothing, TestHeader) Else WebBrowser1.Navigate(cmbUrl.Text) End If
Whenever I try and browse to a page with the 'TestHeader', IE opens up and goes to the page.... However, if I navigate to the same page without the additional header, it loads up fine in my webbrowser control.
I'm instantiating a WebBrowser object and programmatically clicking a button to navigate. Is there a way (property, method, or voodoo ritual) for me to check the browser after it lands on the new page to see 1) the form method that was used and 2) the post data?
I am trying to make a application that will bind User Desired Keys to User Desired Text. This is what I have done so far, it is not very much but it keeps crashing and visual basic is not telling me anything is wrong with it. I basically just want the user to be able to select a hotkey from a combobox. [code]
I'm completely new to Visual Basic, so please be 'gentle' with me.I came up with an idea of a simple app (apps), which is almost done. I'm using Visual Basic Studio Express 2010.What I want to do is (well partially done already):One app (Windows Forms Application) launches another app. I'm using Shell command to start the other one.The other one is located on a network drive, but opens fine. The problem is that the another one (the second one) supposed to start a BATCH file (*.bat) in the same folder where the app is located, but it seems to be running in the same folder where the first app is located.In other words. App1 is C:my appmyprogram1.exe it starts App2 which is on a network drive, i.e.\mynetworkmynetwork foldermy program2.exe. Then 'myprogram2.exe' starts (suppose to) a batch file in the same folder \mynetworkmynetworkfolder, but instead it is trying to look for it in C:myapp . How do I tell the program2.exe to search for the batch file in the same folder where its located?
I want to use webbrowser to go to a web site. This web site has three possible screens that I can get when I try to visit:
(1) A fresh login page, where it does not seem to know me and asks my name and password
(2) The main page of the site, with me logged in from my last visit
(3) A screen that says something like: "Thanks for visiting and logging out. click here to log back in."
I want to make it so that the webbrowser 1 ALWAYS is able to get to the first kind of page. When I have webbrowser1 navigate to the specified URL I want it to *not* be redirected to already being logged in from last time and to *not* be redirected to the third kind of page.
I am trying to make a program so that it goes to the site, enters my username and password, and clicks the "login" button. This is getting messed up because it does not always go to the first kind of page, and, actually, most often redirects to the second or third screens, to my aggravation!
Is there some command I can use with webbrowser and my visual basic 10 program to make it so the webbrowser is NOT redirected without me wanting it to be, so that it always goes into the "fresh" login page?
I have a group of buttons all with different labels. I want to have each of these specific buttons open up the same form, but my problem is when I write the code of form1.show it pops open twenty or so different windows. How to I make one button open just one window?
TDD is supposed to have 100% code coverage. Does this mean one is supposed to write tests for property getter and setters, and other methods that contain no real logic, such as dealing with external API functionality? Below is one example method (which happens to also be the example in this other SO question which deals with how best to test it, if we are going to test it). This method doesn't do much. It's a facade of theSystem.ServiceProcess.ServiceController functionality of stopping a service. Currently this code was not being written using TDD, but if it was, would it be something that one should test? There is very little logic here.est to test it (IoC & Adapter Pattern vs. Detouring) please see this other SO question.

In my project, it is desirable to access built-in color, dash styles, hatch styles by a numerical index rather than their names. For example, I would like to access the colors in a loop from 0 to 140 and display each of these in side by side rectangles in a picture box. Then later, when I click on the rectangle for a desired color, calculate the index of the color from the position of the rectangle in the picture box and use this index to set another object to the clicked color. I understand the coding for all of this except for how to get the colors from the enumeration in the loop and later, after I get the index from the clicked picture box, how to I access the desired color from the enumeration by using the index obtained from clicking the picture box.
I created an exe app in vb.net and I want it to run every 3AM so I used the scheduled task feature of Windows 7. The app has an initial form that will countdown from ten before proceed to the main process. My problem is that the form doesn't poped up. But when I look at the task manager, my app is running. I don't know what's wrong with it because when I tested the app to run at times when I am viewing it, the initial form pops up. I already set everything like to Run whether user is logged on or not. So I really don't know what wrong with my app.
I have written a vb code for the Monte Hall Problem(in my case I have used the example of 3 cards - one of the card is red and 2 are black, you have to choose red to win) But I am not getting the desired results as expected.
Could someone point out my mistakes or advice me where I have gone wrong in my code.I have attached my vb code with this thread.
I am stucked at the situation where I need to disable few columns of a each row ,except newly added row.That is I have 10 columns in grid and I want first three columns that are binded from the rows coming from db as disabled or read-only, rest are editable. if I add new row then all columns of new row must be enabled until and unless it is saved.I dont have any DataKey or Primary key for my existing row or new row. I have to check for some boolean values like IsNewRow. [code] but the problem is that if i click on disabled/readonly rows then newly added rows also gets disabled., which i dont want
I designed a advanced music player, everything is ok, I create the setup, install my computer. Here is my problem, there is a mp3 file at my desktop, right click, Open with, Select my program. But, I realise that I didn't write any code for that. Shortly, I want to when double click on mp3 file. And it should be opened with my program..
-A button (called "btnplayvoice") -A textbox(multi-line enabled, called "txtinput") -Some *.wav audio files in my "resources" (2 of them called "A.wav" and "B.wav", of course there are still some more sound files in my resources xD)Note: the button and the txtbox are in the same form.
i want to make a program with this feature:When I type "B A"(note between "B" and "A" has a space)into txtinput, then i click the btnplayvoice, it will look up and check the resources and see if the wav file exists there, if yes, it will play the related(same as inputed) sound files one by one in correct order. That mean in this case I should hear "B.wav -> A.wav" in this order.
The "named pipe" seems rediculous to pass data between processes (exe's). Is it possible to run a single instance of a VB.NET Class Libary (dll) such that two programs can access the same memory resident dll, thereby passing data via functions and or subs?When I try to make the class library as single instance, the "Enable Application Framework" is greyed out, and thus the option to "Make Application Single Instance" is also greyed out.When I try to call the dll from two processes, I simply just create two instances, so storing data in a module doesn't work
Another area i am now stuggling with is navigating through records one at a time using a database. I am making a quiz and I want the form to populate one row at a time. When Next button is pressed/called, I want to the next row to populate the form, so on and so forth.Problem is I don't really know how to do that.
I am using Windows Forms on VB 2008 Exp. combining with Access 2007 as backend.I have designed a form to use ADODB connection with recordsets to retrieve and display data on label controls on the form.On the Form I have buttons like (First, Previous, Next, Last).... I want to use these buttons to navigate the rows of the recordset.However, I have problem in the codes - when I click the PREVIOUS button, it will tell me that either EOF is true. But if I click the NEXT button, it moves to the next record once.... Clicking on NEXT again, does not move to the next record..
What is the best place (event/procedure) to use the newest record when navigating from record to record on a form.
For example, I want to do a calculation on 2 text boxes that are bound to a dataset. This calculation will be done each time a new record is navigated to.
in a timer and that sometime ended up with error and sometime the browser shows a blank screen and keep on refreshing and other times it shows an error and the application stop responding.
It has come to my attention even as a novice programmer, that there comes a time when you need to step it up a notch and take my programming to another level. For me I think that time has finally come in trying to learn how to use classes properly.
I suspect this is a common rookie fear and the leap to move out of the Form1 Class, or off Form1 is a daunting one. I learned how to add new forms many years ago and to get them to interact with one another in a crude manor, but never really mastered the whole concept of classes.
