I'm currently thinking up a program I can sneak onto my computer at work, and it all hinges on one key question...Does the WebBrowser Object inherit any local restrictions? EG, If Facebook is blocked on IE/Chrome would it be blocked on the WebBrowser Object?
View 2 RepliesI'm guessing there is a really simple answer to this but i've spent the best part of 2 days trying to get it to work and cannot figure it out.Basically, I want is the webbrowser to point to a local folder on a machine. A different one depending on who is logged on. The code I have so far is as follows.
Imports System.IO
Public Class frmFav
Private Sub frmFav_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim username As String
[code]....
I cannot get the URL value of the webbrowser (FavProgs) to take the value of directoryname. If I set the URL value in the properties for FavProgs it does what I want it to do perfectly.
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'm trying to get a local HTML file to display within a WebBrowser in a VB.NET program. I'm using the code below, however it doesn't seem to work, and I can't figure out why:[code]The first method produces the error "" in the Debug console when I go to run it. If I try it with out the @, I get an empty white page. If I change the address, however ,so I know its a broken URL, I get a 404 message, which makes it seem like it's finding the file but not rendering it?The second method does the same as the first except no error is produced, its like its finding the text but doing nothing.
View 1 RepliesQuestion for all of the more experienced programmers out there. I am working on a program with a tab control. One tab will hold a webbrowser control within it. What I am trying to accomplish to have it pull a specific url from my website to the webbrowser control if the person is connected to the internet, BUT if they don't have a internet connection at the time, I would like to display a local html file instead
View 4 Repliesatm i have this If TreeView1.SelectedNode.Name = 2 Then WebBrowser1.Url = My.Resources.Welcome End If
and it doesn't work so if you could please provide an example that world be grate.Also i don't really know how the treeview control works, i know with the combo box or listbox you just have an index of 0, 1, 2, 3 etc. but with the treeview you don't any just one of the things i want to do is whenever the root node is selected i want it to deselect that and select the node that i specify like node.name = 2.
How does the GC dispose objects created in the following 2 scenarios?
1)
Private Function DoSomething() As Boolean
Return New DatabaseManager().Insert()
End Function
2)
Private Function DoSomething() As Boolean
Dim mngr As New DatabaseManager()
Return mngr.Insert()
End Function
In Option 1, I don't create local variable to hold the reference of the object. In Option 2, I hold the reference in local variable.What option is better and why? (if any)
i created more projects using ReportViewer 2005 and 2008 in local processing mode than I can count on my hands. All Visual Studio 2005 or 2008 ASP.NET web forms projects. I always used some flavor of Object data source for the reports.Tonight, I attempted to add the same functionality to a Visual Studio 2010 MVC 2 project and am failing miserably. First, the Add New Item > Reporting > Report is now a 2008 RDLC and not a 2005 RDLC report. Secondly, when trying to add a DataSet, my usual method of create a data proxy class with static methods that return IEnumerables(Of Stuff) will not show up as sources in the DataSources drop down
Thirdly, my only option is to add a Database connection. There is no "Object Data Source" to pick from: Like I kind of alluded to, I have no problems whatsoever actually rendering a report using the ReportViewer control. What I can't do is figure out how set up a Data Source in these new-fangled 2008 reports with Visual Studio 2010 so that I can pump a list of domain objects into the ReportViewer and display the report.
UPDATE: With some more research, I've found that MVC projects do not allow object data sources to be used within them. One solution for my issue is to create a separate project in the solution -- a web application, a service, or even just a class library, to add the report to and design it accordingly.'m still looking for alternatives here, so don't run away too fast!
I've got a datagridview of 4 columns (bounded to a datasource).I've restricted the first column to only numbers The 2nd column can have input all but numbers The last 2 columns can only have letters. Also for the last 2 columns I programmed that the input is converted to capital letters.
See the following
Private Sub validatekeypress0(ByVal sender As System.Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If Asc(e.KeyChar) <> 13 AndAlso Asc(e.KeyChar) <> 8 AndAlso Not IsNumeric(e.KeyChar) Then
e.Handled = True
[code]....
For the first cell I double click on to edit, the restrictions are fine, but as soon as I click a cell in another column it looks like the restrictions from the previous column(s) are also taken with. At the end, if I double clicked a cell in each of the columns, every column blocks all input.

rich text box, when i click Enter, seems it goes into this state

[2] -""
and I get the message pop up box saying can't have more than 2 lines, however the last line is just an empty line? How do i handle the line restrictions in rich text box or how do i ensure that when the user clicks enter I don't move to the next line and move to the next line only if there is 1 line in the rich text box?This returns count as 3 where in there should be only 2, how do i eliminate that white space next line?

View 1 RepliesIs there a way to make specific queries from a specific table to another, and then export it to VB??. I have an access database, in which I have 4 tables and 1 query. There is one table called "Customers","Gears" and "Articles"; the last one is the relationships with the ID between the tables from Articles, Gears and Customers, becuase a customer may have more than two Gears, therefore the Articles as well.
So in VB I made an interface in which it conects to the database to show in a combobox all the customers, after that if I choose a customer, then it is supposed to show de gear in a listbox which the customer has, but the problem is that it shows all the gears from the query and not the specific one from that customer, also it repeats in the listbox the same gear twice or more. I think it is problem from my query, but I really don't know how to use very well Access, so I am depending on VB. This is the code that I got so far (Note in my

I am having problems downloading files possibly due to the file extensions not matching the actual file. What is happening is the File.Exists check is returning false for these even though the named file does exist. Is anybody aware of anything in IIS or even IE which would cause this? I have seen this with .txt, .exe. and .avi files. The .avi works of as long as the file really is an avi and not renamed from something else.

The problem I have is that the user still has the possibility to place restricted characters in a column by pasting them in (with ctrl+v or right click-->paste), because the keypress doesn't notice the pasting.What should I do to make it impossible for the user to use restricted characters? In other words, how can i check the text the user wants to paste in a cell (cause that's the only other way to input data I can imagine)

View 2 RepliesI have a program which opens up a webpage through a WebBrowser object in c#, and does a bunch of operations with it. Now I need to integrate this functionality into my own webpage.
That means that either I need to take the c# code, and somehow make it work in my webpage itself (put in a WebBrowser object, set up event handlers, etc), or I need to somehow have my webpage open this program on my server, fire an event to start, and receive input from it. It is very important for me to use a WebBrowser object (or even WebKit.Net) because there is a lot of javascript, etc on the page that needs to be processed.

So I am currently using the method of combining a timer with a WebBrowser control to constantly check if some particular text has appeared in the WebBrowser control on my form. The text is dynamically generated after some arbitrary amount of time depending on the user's internet connection speed. (I'm using DOM to do this). The code to check for the HtmlElements lies within a function, which is turned called by the timer.
I find that this is kind of crappy and occasionally lags the UI interface, if not making the entire program behave sluggishly. I have been thinking of just using a simple while loop in a worker thread to take care of the issue, but I understand that new threads cannot interact with the UI thread directly (including controls); they have to call wrappers that are present within the UI thread.
So my question is, can you declare a WebBrowser control and still interact with its HTMLDocument properties if you declare it within a worker thread? I don't want the while loop to be executed within the UI thread (by using a wrapper), since that would defeat the purpose. I would also like to avoid DoEvents() as much as possible...unless that's the only way to do this thing?
