Added Reference; Microsoft Internet Controls (COM Tab)
Jan 8, 2012
I was trying to make my program see if facebook.com was running in internet explorer.
I added the following
Private Function isFaceBookOpen() As Boolean
For Each ie As SHDocVw.InternetExplorer In New SHDocVw.ShellWindows()
Dim filename As String = System.IO.Path.GetFileNameWithoutExtension(ie.FullName).ToLower()
If filename = "iexplore" Then
[code]...
And added reference; Microsoft Internet Controls (COM tab) but i also need to add this reference; Microsoft.mshtml (.NET tab)
Problem is that i can't find that reference. BTW, I want the function to be triggered by a timer.
I have been writing VBA code for MS Access for years, but am starting my first project that will need to retrieve data from the Internet. I have come across code samples that use "Microsoft Internet Controls" and "Microsoft HTML Object Library", and I can make them available references in VBA, and available methods and fields etc. show when writing code, but I cannot find any documentation for these APIs. Does it come with MS Office on the CDs (if so, where?), or is it available over the Internet somewhere?
and from VB6 project I reference to Test.dll but an error messege was appear A reference to Test.dll file could not be added (If I create VB NET project and reference to file Test.dll it OK )
I'm looking at writing a plug in for microsoft internet explorer. but I can't find any documentation for doing so in vb.net so the questions are: is it possible to write an IE plug in in vb.net? where is documentation on it? and of course documentation on installing it. Why? I want to write a password plug in like Roboform for the most part as an educational project second as pasword manager I can use myself..
I have a web site project where I need to use the System.Security.Cryptography.Xml.SignedXml class. I added the Dll System.Security as a reference and imported the namespace into my project. It compiles successfully but when I debug the project I get a compilation error:
Compiler Error Message: BC30002: Type 'System.Security.Cryptography.Xml.SignedXml' is not defined.
I'm trying to learn how to call functions in C DLLs from Visual Basic programs. I'm new to VB but have years of experience in C programming & want my functions to be usable by people who are more familiar with VB.
I managed to create a C DLL & call the functions from a C program. One difficulty I had was that I wanted to put my DLLs in a MyExes directory so I could easily have several unrelated programs call them. It was far from obvious how to tell the compiler & linker to look for the DLL in some arbitrary folder but I eventually found out.

Now one of my difficulties with DLLs & Visual Basic is how to tell Visual Basic 2010 Express to look for functions in a DLL in some arbitrary folder. I tried to use Project->Add Reference, then in the Browse tab went to the folder & DLL I wanted to use, but got the message box:"A reference to C:ProgramFilesMyExes....dll could not be added. Please make sure that the file is accesible and that it is a valid assembly or COM component."I've tried to find a walkthrough to take me through the steps of using C DLLs in VB 2010, but so far had no luck.
I have two FlowLayoutPanels in a Form. The first read images from a DIR and expose them generating so many PictureBoxes are necessary. The user can drag an image and drop into the second Panel. All works fine. Now the problem is how can I know the name of the image contained in the PictureBox in the dropped Panel so that I can save it? I tried to recover in a ListBox the name of the images during the population of the first Panel but I don�t know witch may be the reference with the dropped PictureBox.
I have added a reference to the System.Data.SqlClient, but i am not able to use its components while coding, But when i import it in the form class i able to use the component.
So,Is importing a namespace and adding a reference two different things?
I've been working on my game for a while, in a non-online multi-player state it is complete. My goal is to add LAN or Internet Play support.My game is coded in Microsoft Visual Basic 2010 Express, It relies heavily on timers.Currently you play against the AI, and there is a Local multiplayer mode, using mice, controllers or the keyboard.At the moment, it is a two player, (Or 1 player against the AI) game, from my understanding the standard Client-to-Server option wouldn't very efficent, the best choice would be a peer-to-peer system.That being said, a lot of the stuff could be done client side, like for instance, the particle engine and Dynamic Rendering.[code]
I understand the page lifecycle and how i need to add the dynamic controls on page_init if I want to take advantage of viewstate. Also I know that I should try to avoid dynamic controls when possible. The dynamic controls are created depending on an object that is created from custom event arguments sent from a custom treeview. Problem is I need viewstate so I need to create them in page_init but I don't have the event args to create the object that tell me what controls to add until later in the lifecycle.
Private Function GetEventArgs() As npTreeViewEventArgs Dim control As Control = Nothing Dim e As npTreeViewEventArgs = Nothing
[code]....
I use this in page_init to create my object and controls.
I'm just starting out using vb.net and i am writing my first application. I have added some comboboxes at runtime to my form using the code below.[code]Now my question is now that i have these controls added to the form, how can i iterate through them all and collect the values for sql injection. I have given each combobox a specific name when it was created such as Ball1, Ball2, Ball3.[code]
I created a control so that I can add label, txtbox and checkbox during runtime. I was able to do this successfully but after this, I need to get the state of this checkboxes every time the user check it, RUNTIME.[code]...
How do you refer to controls that are added at runtime e.g. I can add a combobox and a handler, but trying to reference the controls name in code gives an 'not defined', error so in my example, the control is visible, but I cant populate the combo box or use it in anyway.
I'm trying to play a music file. When I went to add reference and clicked on Microsoft.DirectX.AudioVideoPlayback.dll, it won't load. How do I resolve this problem?
Is this the preferred method for playing audio files?
I have a number of user control dynamically added to a page, and user interaction with these dynamically added user controls need to be handled by the control's parent. Is this what is referred to as "event bubbling"?How do I do that in VB?
I have created a datagrid of my own in vb dotnet and converted to dll. I add this dll to a project.i have 2 forms and i have added this control on 2 forms. When i run the project and open 2 forms simentaneously an error " reference not set to an instance of an object" occurs on acess of any property of that control.
I am currently wokring on a project, which is going to serve as an interface for accessing various documentation and reports. It is basically just a tabcontrol with a few pages that will be poppulated with buttons which will open the appropriate document.I am trying to allow administrative users the ability to add new, edit or remove buttons which all seems relatiively simple, but have run into the problem of how to persist the changes once they are made. I want the setting to be stored centrally, either in a SQL table or on a network share
I am creating a program which allows the user to add some buttons during runtime. Each button can be moved, sized and added to any tab on a tabcontrol. What I would really like to do is binary serialize a class that contains the properties of each button including which tab it's on.
So I would like to explain what am I doing before I post the question. I would make a textbox in the form, then I add a Microsoft Speech Object Library reference. Then using Microsoft Speech, I would have the text-to-speech option. In the same class I would add this code:
Okay normally this was easy to do, but now with IE9 Visual Studio 2010 hangs and crashes. The problem seems to be even worse because you can't build an Interop.mshtml.dll to match version 9. I've tried using the VS command prompt with no luck. Allegedly this is how it is done, but there are no known examples that actually work. If anyone has done this with success
i am wanting to add handler for controls i add at Page_load at page load i added several image buttons and applied the image urls using -i used the borderwidth propertiy for padding as was having trouble getting a cssclass to work. [code] what i want these Image button to do is when clicked a larger image in another panel will appear so i will need to assign the clicked buttons image url to the large image controls, image url
I want to ask a question about adding controls in design time (controls may be any win form control or a user control) and adding the control in run time.
If I add an InputPanel control on B, i have no problem.If I add an InputPanel control on A and B, i have no problem.But if I add an InputPanel control only on A, I'm unable to open the designer for form B.
The erros is : Could not load file or assembly 'Microsoft.WindowsCE.Forms,
I've dynamically added 20 pictureboxes to a panel and would like to see the panel scroll when I use the mouse wheel. To implement this I have tried to set the autoscroll to true on the panel control. Here is the code.
For i As Integer = 1 To 20: Dim b As New PictureBox() b.Image = Nothing
[Code]....
It works for "button" control, but not for the "picturebox" or "label" controls? How can I implementthe scrolling affect using 'mousewheel'?
