VB6 - Video Series Is Focused On The Interop Forms Toolkit ?

Jun 10, 2010

Visual Basic Interop Video Series This how-to video series is focused on the Interop Forms Toolkit and working with Visual Basic .NET and Visual Basic 6 together. The Interop Forms Toolkit allows Visual Basic developers to migrate their Visual Basic 6 applications over to .NET using a phased migration strategy. Instead of having to convert the entire VB6 application at once, the toolkit enables .NET Forms and User Controls to run directly in Visual Basic 6 applications so that you can build the pieces that you need over time.

Download the Code: Videos 13

You will need: Visual Studio and the Interop Forms Toolkit 2.0 in addition to Visual Basic 6.0

.net - Form Load Event Fires Twice Using Interop Forms Toolkit?

Sep 18, 2009

I've been following a codeproject article on using the interop forms toolkit (basically a way for developers to slowly upgrade their VB6 projects to .net by allowing .net components run in VB6)

[URL]

While the .NET form is working fine in all other testing projects and environments, I've found that the Form_load event is actually firing twice once it's in executing in the VB6 runtime.Not only annoying, its forcing my initialization code to execute twice (causing all kind of problems on the second run).

If (runBefore = True) Then

Subsonic And The .net 2005 Interop Toolkit?

Nov 10, 2009

I have an application I am converting over from vb6 to vb.net 2.0/3.5. Using Subsonic 2.2 and the vb.net Interop Toolkit 2005. Cannot seem to get the .net form using subsonic to work inside the interop environment.It keeps saying it cannot find the subsonic service provider in the app.config. But I know it is there. Has anyone used these two toolkits together successfully? Will subsonic even work inside the interop environment in that way?

.net - Create A Video Stream (AVI) From A Series Of Images?

Dec 8, 2009

There is an IP web camera that I wrote a .NET class for sometime ago. It's basically a Timer implementation that pings a snapshot CGI script from the camera every five seconds. The camera itself is very rudamentary; it does not have any sort of API for me to work with, the only thing I can do programmatically (remotely) is invoke this script. The script returns a 640x480 JPEG image. Simple.

Now what I need to be able to do is take a days worth of these images, and create a "time lapse" AVI video stream out of it that will eventually be embedded into a web page. How can I do this with VB.NET?

VS 2010 Interop And Modal Forms?

Feb 9, 2012

I have a .NET application that calls a method in a COM component to show a dialog. Unfortunately, you can't pass the .NET form to the COM component to set the owner form without a type mismatch:

_ComForm.Show vbModal, _DotNetForm

So, what that means is the form is displayed without a parent form. The problem is, if the user launches the COM form and then while the dialog is shown, clicks to another application and then returns to my application, the COM form is now behind the .NET owner form and most users won't know how to find that window. Is there any way around this?

Force Visual Styles When Using .NET Forms Interop From VB6?

Jan 4, 2011

I have created a VB.NET Class Library that exposes some COM Interop sub routines. These in turn show various forms that are contained within the Class Library. When the forms are shown from VB6 they do not inherit the visual styles of the operating system and act like VB6 controls.

I gather that this probably by design but is there some way to force/control visual styles manually in the .NET assembly? I would imagine that if I use a manifest in my VB6 app then everything will use the correct style but I would like to be able to control this myself if possible because we are using 3rd party controls in VB6 that do not require a manifest.

Forms :: Chart (Series Colors, Graph Refresh On Timer, Etc) Application That Ties Into A SQL Database On The Back End

Dec 29, 2011

I am working on an application that ties into a SQL database on the back end. Currently the main form contains a series of combo boxes (Graph type, data format, location, and customer), two date pickers, and a button to launch the selections in a new form. Everything works just fine except there are a couple of things I can't seem to accomplish.

Example Data:

[CODE]...........

Case Select (with commented out lines for variations attempted):

[CODE]..........

1) I would like to be able to use some sort of case statement to color the bars in my chart based on value. I have tried approaching this in a couple of different ways but neither of the options seem to work. First, I tried this (the If Not is used because depending on what values are passed to the stored procedure in SQL, different columns will be returned):

[CODE]..........

Only one series is created with this method, so I can see how/why a Select Case would set all bars the same color. I have also tried creating a series for each row in the returned dataset but it results in 22 bars of different colors, for each of the rows (484 bars):

[CODE]..........

So is there any way to modify the second set of code there to only select the value from the "Percent TMHB" cell that corresponds with Row(i), rather than ALL values from the "Percent TMHB" column for EACH Row(i)?

2) Since I am drawing/creating these graphs in a new window, is there any way to also create a new timer on the "newFrm" and have the tick refresh the data? I've struggled with this but I feel like it should be easy. Say someone chooses a "TMHB", "Percentage", "Chicago", "All" (Graph type, data format, location, customer) and launches the graph, which opens in a new window, then they want to do "TMHB", "Percentage", "LA", "All" and have both windows up, refreshing automatically throughout the day. Can I somehow store the SelectCommand.Parameters values in the new form/timer so that it will query the database again every 5 minutes?

Example code for the StoredProcedure and creating the new form:

If combo_GraphType.SelectedItem = "TMHB" Then
Dim newFrm As New Form
Dim newChart As New Chart

[CODE]..................

I'm fairly new at this. I havn't done any programming in years and I've never been amazing at it, I've already got this directory list done so this is the next step in my project...

Forms :: Small Bug With WebBrowser Control And Flash Video?

Nov 27, 2011

I have created a VB.NET project that includes WebBrowser control. The web browser control navigates to html page that embedes a flash movie. Everything works fine except that when I want to exit the fullscreen mode of the video by pressing (Esc) key, it doesn't exit. If I view the html page with any other browser (Internet Explorer, Firefox, ...) it works perfectly. You can download the project from the link below. The files are in the Debug folder.

Windows Encryption Toolkit For .NET

Jul 29, 2009

I'm rewriting a VB6 application that used the Windows Encryption Toolkit and Blowfish encryption. Does anyone know if the Windows Encryption Toolkit exists for .NET? I would use a different type of encryption if necessary, but we have 2 programs where I work. Users encrypt files with one program and send them to us and we use another program to decrypt them. I'm worried that if I don't use Blowfish encryption again, users will send us files encrypted with AES for example and we won't be able to decrypt them.

Monitoring 12 Video Feeds From Video Cameras - NEXT Or FORWARD Button On My Monitor Form

Dec 24, 2009

I am monitoring 12 video feeds from video cameras. Now I have more than 12 cameras, I have 134. But I will only monitor 12 cameras at a time. By Monitoring I mean, I have 12 small video screens on the form that I can see the video. The way I know which cameras are active, so I can monitor them is by a boolean value in a sql database. I run a Store Procedure in my program, and spit out the results in a XML file. I then read the XML file in a loop. This XML file will have a list of the camera names I need to monitor.

So that is for 12 video feeds. Now, I want to have a NEXT or FORWARD button on my monitor form. So when I click this it will give me the next group of cameras, 13 to 24. Now if I only have15 cameras that are active, that means the first group is 1 to 12, then the second group is 13 to 15 cameras. So I will only have 3 to monitor on the second grouping. One thought I had was to have another field in my table to mark as already as an active monitor, so when I run the SP, i will not select that row. But I need to select 12 at a time. Or I can make a number of xml files, one xml file for each grouping of 12, but I need to figure out how I can select the next group without re-selecting the first group. I have no code at the moment, I'm on my non-programming computer.

Installation Of ASP.NET AJAX Control Toolkit

Mar 8, 2011

I am working on a development project with a number of other individuals using TortoiseSVN. I followed [URL] to install the toolkit.

I tried to have a look at the configuration for another project where Ajax control toolkit was installed however I have cannot get Ajax elements to appear in my solution explorer would anyone know why this might be? I had a look at this other person's solution explorer and they have the ajax control toolkit.dll, ajaxcontroltoolkit.pdb and other folders (ar, cs, de...) within a different type of folder (looks grey and has a cog symbol) called 'Bin'

I am using Visual Studio 2008, .Net Framework 3.5 and I tried the ajax control toolkit framework 3.5.
