I have put together some code to login to one of my websites [code] The problem is when i display the sites source code it still shows the source of the login page, rather than the page you goto once you login
View 2 RepliesIssue: Can't find a way to utilize process.start to enable automatic login to various websites.Program: A simple window form application with a desired module/form to store user passwords and websites and launch a login from the form (a very basic "password manager" and launch) Side-issue: Data storage (Not yet explored because of inability to solve main issue) , would like to use text file to store System.Security.SecureString data-type.
Narrative: I'm really new to all of this but not lazy or unwilling to do the work. Two and-half months of no less than 14 hours per day reading and applying myself to VB language and VS IDE. Been able to solve all my own problems thus far with help of Web or my $600 library investment, and have a working app that I've been able to deploy. However, neither of these assets seems to hold answer for this problem, and unlike others I've encountered, I can't find a work-around.
Potential Answers: It seems that answers may lie within an HTML/XML/JS/AJAX get/post route, but this is an entire new area of study/research that I hope to avoid if there is indeed an answer utilizing Process.Start. There also seems to be a potential to solve my problem using ASP.NET, or using System.Windows.Browser and HTMLElementCollection (for the last I've only found snippets of code that utilize My.Settings.UserName, & My.Settings.Password, and it is unclear to me if these settings reflect the login to user machine or to actual desired site).
My Hope: (which may be forlorn) is that there is a simple explanation on how to plug a value in to the last parameter of Process. Start ---"Domain". I'm assuming Domain is not what I would normally interpret to be the root of a website, but is instead particular to user machine. I've found no good examples, other than a hint of using System.Configuration.ConfigurationManager, and statements that old VBCode made access easy.
My Assumption: I'm thinking this is another area where my newbie status has made me a believer there's a solution within my grasp before I found the answer but after I made a commitment. VS2008 fooled me in a similar manner in three other areas thus far, the PrintDialog control duped me into thinking printing was an easy process, HelpProvider control had me totlally convinced that Help installation was a snap, and OneClick deceived me into believing deployment was oh so simple.
Process.Start may be another place I've been had, but if you speak pretty good newbie Anyway, here's the small bit of code I've been playing with but without luck (Win32 exception, parameters are incorrect:)

I have a hashing method whose operations depend on input to the function. Profiling the program has shown that too much time is spent evaluating this hash method. I want to try changing it into an expression tree, so the inner loop checks can be done once.
Here is a simplified version of the function (I undid some obvious optimizations for the example, and took out any input validation):
Private Function Checksum(ByVal inputValues As IEnumerable(Of UInt32),
ByVal declarations As IEnumerable(Of String),
ByVal statements As IEnumerable(Of String)) As UInt32
Dim variables = New Dictionary(Of Char, UInt32)
[code]....
I want to create a function which takes the declarations and statements and outputs a specialized expression tree representing a function which takes an IEnumerable of UInt32 and returns a UInt32.Follow-Up:I succeeded, and the speed-up was ridiculous (an order of magnitude). The main things I had to learn where:Use Expression.Lambda and Expression.Compile to get a delegate you can actually use.The Expression.Block factory method has a 'variables' parameter you (essentially) use to declare locals.Expression.lambda has 'parameters'.If you call Expression.Parameter twice, you're dealing with two different variables (even if their name is the same)! Store the result for later usage. Same for labels, etc.The result of a BlockExpression is the last expression in the block.
I am using VB 2010 and have the following code written in C that is used to access some PDF properties. translate this to VB?
[Code]....
I have a line of C# code and can't translate it correctly. 'myString' is a string and 'a' and 'k' are both UInt:a += (uint)(myString[k + 0] + (myString[k + 1] << 8) + (myString[k + 2] << 16) + (myString[k + 3] << 24)); Translators for VB suggest the following but I get "Operator '<<' is not defined for types 'Char' and 'Integer': a += CUInt(myString(k + 0) + (myString(k + 1) << 8) + (myString(k + 2) << 16) + (myString(k + 3) << 24))
View 4 RepliesI have this working on VB6 that saves a query in a excel sheet:

The XLSNombre is a variable with the name of the excel file that has been set before. The connection I have in .NET is to SQL server (but is the same). How can I use this code (or..how can I make this code work for .NET) or what is the equivalent of this for .NET? I found some solutions but with inserts of single rows or I have to set the title of the columns, I dont find any "simple" solution to do an "insert into" (like the code I use in VB6).

View 3 RepliesI've got a DateTimePicker control on my form. The normal behavior is for it to allow the user to "move" between value fields with the arrow keys and remember the last date part that was highlighted when the control loses focus. Then, when the control gets focus again, that date part is highlighted. We all know this, I'm sure.What I want to know is how to access the control's selection properties/methods in order to have my DateTimePicker control always highlight the month portion when a user enters the control, regardless of what the last date part highlighted was.

now, in my code, i also have if ex = certain error. i'd like it to go back to the top of the try. reason for not letting it do its thing is, i am wanting it to retry it, under the same item. So, is there a way to goto a portion of the code.
I have created a class which generates a form in code. I have hooked up the buttons and a text box so that they work. Now, I am trying to hook up the Resize event (and probably will need other events) for this form. How do I do that? If I can understand how to do it for the Resize event, I should be able to apply that to whatever other events I might want to use. I can't just put "Handles frmMyForm.Resize" or "Handles Me.Resize". I get the message "Handles clause requires a WithEvents variable defined in the containing type or one of its base types." This all has been a learning experience.

View 3 Repliesi was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?
im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.
my requirement is that i have to count occurrence of a certain date and between two months
