I'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 3 RepliesI 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.
I'm trying to create a "wrapper" DLL to provide additional functionality on top of an existing DLL. Here's what I'm doing, it may be the wrong approach.The existing DLL is basically a .net version of WinSock. It has lots of public methods and events.The DLL I'm trying to create will provide specific file processing methods, and notification events, which will then utilize the WinSock DLL totransfer the files. This wrapper Dll is intended to encapsulate all of DLL #1 methods and events.
So what I'm doing is having my new DLL reference the existing one, and create a new set of events, some of which get raised by handling DLL #1 events.So I end up with two DLLs, one of which is dependent upon the other. When I try to use my DLLS in a Forms app,I am able to use my wrapper to call methods in the WinSock DLL. Some events that are raised within my wrapper are properly handled by the forms app.The events that do not work (get raised) are the ones which are raised by handling the other DLL's events.This seems to be because the WinSock DLL's events never get raised, when they apparently should be. The WinSock object in question was declared as "WithEvents".
I know what is the actually DLL wrapper and how to create? I'm actually want to use a DLL which is written in Delphi and I try to do some search on the internet and I came across the term of wrapper.
View 1 RepliesFor some reason this error started popping up today on one of my projects.[code]...
If I go into advanced compile options and change it to not generate and debug info, my project compiles fine.
I have tried setting the permissions on the Release folder to full for everyone, so I would assume it's not a permissions issue. Also, I don't see anything in my log files that would provide me with more information about the issue.
What is the Best way to create scheduler ?
I can think two ways,
1) to create endless loop that keep checking for time of day, so if i have an event (stored in my DB) that should be execute @ 14:30 the loop will compare in every loop the current time against the DB time so when the current time will be 14:30 the event will be executed
2) the same as above just using Timer instead of endless loop.
the problem is that both methods seems to be inefficient because at least 95% of the checks will be for no use.
so is there any methods or some way in VB.NET to raise an event in a specific hour without keep checking the current hour every second ?

View 3 RepliesI 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?

View 2 Repliesbuilding 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 RepliesThis 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 RepliesWe 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?
