How To Force Webbrowser1 To Go To Desired Page
Nov 20, 2011
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 an asp.net website that is using update panels on the page that i cant get to reload from the server. I have this for the disable page cache on the master page.
'Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1))
'Response.Cache.SetValidUntilExpires(False)
'Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches)
'Response.Cache.SetCacheability(HttpCacheability.NoCache)
'Response.Cache.SetNoStore()
When I click the browser back button to go back to the page it says the page has expired. the other pages on my web site work and call the page load, the only solution i found but cant use is to wrp the whole page in an update panel, but i cant do this becuase i have a report viewer on the page that does not work with ajax.

I have a web app that has a base page.Each page needs to inherit from this base page as it contains properties they all need as well as dealing with the login rights.My base page has some properties, eg: IsRole1, IsRole2, currentUserID, Role1Allowed, Role2Allowed.On the init of each page I set the properties "Role1Allowed" and "Role2Allowed".[code]Should this functionality be in the base page or should it somehow be in the master, and if so how would I get access to all the properties if it was?As there are multiple people working on this project and creating pages some are forgetting to inherit from this basepage, or call the base pageload when overriding it.Is there any way to force them to do this?

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've got a handful of dynamic controls populating an ASP page, with VB.NET in the back-end.What I need is when the user changes the .TEXT value of a textbox and the page posts back, the .TEXT value of a Table Cell changes to reflect that change (it multiplies the value of the textbox by the value of another cell).But a Table Cell can't be set to AutoPostBack, and I can't for the life of me figure out how to programmatically refresh the page (force a postback) in the TextChanged event for the textbox.

I'm printing a multi page document with PrintDocument() and I need to be able to force a page break from within my code. I've tried adding vbFormFeed at the appropriate spot but it's ignored.
Is there any way to embed something into my page buffer so that it will force a page break?

I have an ASP button for which I have set the OnClientClick property to display a javascript confirm message. However, I only want this message to be displayed AFTER all of the client side validations have passed. How can I do this? Essentially, I believe that I need to force Page level validation from the client and then, only if it passes, display the confirmation box.

I have a requirement to print a number of records from a database. Each record refers to a second database that holds x number of related records. Just like and invoice header and line items.
I first print the report heading on the first page Something like "Invoice list for May 2012"
I then print the Invoice record headings under the the report heading Something like "Inv# Cust # Cust Phone Address 1 Address2 etc"
I then print that data from the original recordset Something like 1234 DR127 555 555-1212 Somewhereville 245th street
I then print the Line item headings Something like "Ln# Item# Description Qty Cost Selling Extn"
NOW Here is my problem: I never know how many line items there will be so can not predetermine when I will need a new page. I do have a way of telling when I am at the bottom of a page by using the text height and incrementing a value for each line
BUT I cannot figure out how to break out of the line item loop, start a bew page then carry on where I left off.
Once all the line items have been printed I need to start the next invoice by printing the Invoice record headings again followed by the header data followed by the line item headers followed by the line items for that invoice.
I have said that the page break may come while in the line item loop but it actually cold come anywhere in the overall loop.

I am working on a custom framework above the .NET framework, and some instructions are not written / called at the good places.
For example, a postback is done on the same page. Then, a Response.redirect occurs right within the page_load; but at this point, the new values of the controls of the page are not yet handled, so they get lost...
Therefore, I wanted to know whether it was possible to force the pagelife_cycle to go forward before the call to response.redirect, so that I can get the right values.
I can't just make that call in another function, because the page I am working on is called by many web applications (about 1-2k), and it would completely change their behaviour, which is not acceptable!

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'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?

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 got the following things:
-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
