View 1 RepliesUnable To Create A COM Wrapper For That OCX?
Sep 12, 2011I'm trying to add a control on my form and each time an error pops up : "Failed to import the ActiveX control. Please ensure it is properly registered". I'm currently upgrading from VB6 to VB.NET (VB2010 running on Win 7).I installed vb6 on my win 7 PC and i can still add that control on any form - so definitely the OCX is properly registered. My guess here is that VB.NET is unable to create a COM wrapper for that OCX.

View 2 RepliesCreate A .exe Wrapper For A Flash Player?
Feb 9, 2010I would like to create a .exe wrapper for a Flash Player using VB.NET. I am having a few problems.1.I seem to remember being able to import Flash Player as a control into Visual Studio (2008 Pro). For some reason, I can't seem to VS to import it anymore. (I tried using the OCX from Visual Studio) Perhaps I'm looking for the wrong file. What file am I looking for?
2.Is including Flash inside of a VB program legal?
3.When a control is included in a VB.NET program (such as Flash) does the control need to be distributed in a separate file, or will the compiled application contain it in the ".exe"?
I was able to import the control as the Flash10b.ocx from c:WindowsSystem32Macromed directory as a COM component. Question 2 and 3 still remain.Is there documentation on the ActiveX control? I am trying top figure out the API for ExternalInterface.

View 3 RepliesRead-Only Wrapper For Customized List
Dec 7, 2009I have created a customized list (by implementing IList) where I added a few special methods. Sometimes (but not always), I only want to expose this list as read-only. To do this for normal lists, I use the Collections.ObjectModel.ReadOnlyCollection wrapper, which works fine typically. But it seems by passing my customized list through this wrapper, my added methods are no longer visible, which defeats the whole purpose of having this customized list object in the first place. How can I create a read-only version of a customized list?

Building A ASP.NET Profile Wrapper To Use With An ObjectDataSource Control?
Dec 26, 2011building a ASP.NET profile wrapper to use with an ObjectDataSource control. I would like to have the serialized profile data that I have defined in web.config be accessible via a FormView control within a user control. I'd like the users to be able to view and update their profile data. I have part of the code but am lacking the experience to complete it. I'm using a aspx page with some text boxes and having users update via a simple form now but I need something more reusable and efficient, not to mention moving the logic to a middle tier. I see that the ObjectDataSource control has some intrinsic ability to view profile common data but that seems to be limited.

View 4 RepliesPut A Wrapper Around Some Functionality That Uses A Web Service To Return Some Information?
Nov 28, 2011This is annoying. I'm trying to put a wrapper around some functionality that uses a web service to return some information. The intention is to wrap all of that communication into a dll such that the user can simply call functions from the dll to get back information, without needing to care about the service.As far as I can tell, that isn't possible, because the service information, as far as bindings and endpoints, HAS to exist in the app.config of the program that references the dll. That means that anybody using this dll won't just be able to add a reference to it and use it, like they would with any other kind of dll, they must also edit their app.config to add in a bunch of information. That's a simple copy and paste job, but it's incredibly unfriendly, and exposes some of the internal workings of the dll to casual inspection.
View 8 RepliesVB6 Conversion To Wrapper To Prevent Null Exceptions
Sep 14, 2010We are converting a large VB6 application to VB.net. The problem we have all over the code is the .NET converter did not "reorder" the "IF" and other statements in the code to stop execution when a DBNull value exists. For example, we have code like this all over the place.
"If rRow.Item("av_election_id") > 0 And (rRow.Item("Challenged") <> "SUSPD" Or IsDBNull(rRow.Item("Challenged"))) Then"
This causes a error when "rRow.Item("Challenged") is dbnull
The line of code below corrects this issue but we have thousands of lines of code to reorder and refactor.
If
dtAVVoterRow.Rows(0)("av_election_id") > 0
And (IsDBNull(dtAVVoterRow.Rows(0)("Challenged"))
OrElse dtAVVoterRow.Rows(0)("Challenged")
<> "SUSPD")
Then
creating a wrapper class or something to allow us to keep the first example of code above where it will not throw an error when encountering a Null value? I don't know if a wrapper that reordered the If statements, or captures the error but continues the execution somehow?

Red Color Of One Image To The Alpha Value Of The Second?
Jun 30, 2009I am trying to create a function that would take 2 images. 1 of the images is a grayscale image and the other is a normal image. What i want to do is apply any of the R or G or B of the grayscale image (in grayscale image r=g=b so it makes no difference) to the Alpha of the second image. i DID succeed on it. However the code is EXTREMELY slow. It takes 1 second to perform it. And i have to perform the function atleast 30 times a second (it will be outputting to a Decklink card). Here is the code:
public function createOverlay(ByVal Main as Bitmap, ByVal Key as Bitmap) as Bitmap
For index as integer =0 To (Key.Width*Key.Height)-1
Dim crntX= index Mod(Key.Width)
[code].....
This function will have to run infinitley until the user presses stop and keep updating the output buffer. How can i make it faster? ( i need at least 30 executions per second)
Support For Alpha Transparency?
May 2, 2010I would like to drop a few buttons onto a picture box or a container control that has a background image set.
I would like to have the button's image be an alpha PNG file.
I can manage the mouse over and click such that the button behaves exactly as one does on a web page.
I struggled with it in vb.net 2005 with no luck. If you take a PictureBox and lay it on top of another PictureBox, and set its images to alpha PNG's, and its background to transparent, then the form shows up in the alpha blend, not the other picture box.
And if i accept that i am limited to the background of the form, then it's performance then becomes unacceptable.Since i can Graphics.DrawImage onto a PictureBox's image fast, i assume that the folks at Microsoft must have decided to use the form's background (and slow painting, and not the other controls and the z-order), by design. I cannot for the life of me figure out why they have made that choice.
So my question is this:Does vb.net 2010 support the layering of controls that supports alpha transparency, and can we now create a custom-control with a transparent background?

Me.ForeColor = Color.FromArgb(1, 255, 255, 255)
Me.BackColor = Color.FromArgb(100, 40, 40, 40)
Me.ForeColor = Color.FromArgb(100, 255, 255, 255)
The result of any of these two lines is exactly the same ( no change in alpha ). The colors take ok though.
