I have a .NET application which is using the Microsoft.mshtml PIA. It frequently experienced exceptions with a message saying that the Microsoft.mshtml assembly or one of its dependencies is missing. Weirdly enough, this happens on some machines, but works fine on others! (actually, it works fine on the majority of machines)

View 1 RepliesI have created an application in VB.Net 2010 and am using an Access 2010 db. Connecting to this DB I use the Provider= Microsoft.ACE.OLEDB.12.0 and it works fine on my machine. This was a recent update from using Jet as that provider was having issues on client Win64 computers that had Access 2007 or 2010 installed.Basically my issue is that I get the error that Microsoft.ACE.OLEDB.12.0 is not installed when I try to run the application on the client.
The problem however, is that I do not want ask the users to install Data Access Objects in addition to .Net 4.0. I want a simple install that they can run and upgrade to .net 4.0 if they need to. The above thread states a solution as "You can also consider to use ADO.NET object in System.Data.OleDb namespace to connect to the Access database instead of the Provider. In my opinion, this is the best choice since the ADO.NET provides you the powerful data access objects." This sounds like a great option, however I cannot find any way to install the ACE dll and get it to work on the client.what do I need to include in the client installer to get my application to run on systems without Access installed? Do I just include the ACEODB.dll or is there something else that needs to be done?
This question is about deploying a VB6 application that uses an interop component created in VB.NET, specifically, a .NET dll.Using Regasm.exe, I was able to create a .tlb and use it on the dev machine to add a reference to the VB6 project, but how do I go about deploying on client machines, particularly the .NET component?

I have added COM control AxWindowsMediaPlayer to form in vb.net.and just have following code
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End Sub
End Class
abase.mp4 file is kept in directory where exe is there. Every thing runs fine on dev m/c but on client machine application is not lauached.When Interop.WMPLib.dll and Interop.WMPLib.dll are copied to the exe file directory then application is lauched at least but file is not played automatically and even on pressing play button its not played.Is some dll registration required to make it work? or some references needed in project?or some changes on user machine?

View 1 RepliesI have a vb.net 2.0 winforms project that is full of all kinds of business reports (generated with Excel interop calls) that can be run "on-demand". Some of these reports filter through lots of data and take a long time to run - especially on our older machines around the office.I'd like to have a system where a report request can be made from the client machines, some listener sees it, locates a server with low-load, runs the report on that server, and emails the result to the user that requested it
View 2 RepliesThis is a VB .NET 4.0 WinForms application. There is a mysql data-source involved with this project. The target CPU is set to any. Problem: When running this application on any computer that has VS 2010 installed along with the mysql connector it runs flawlessly. When installing on a virgin system(ie. No developer environment installed) but that machine does have .net framework 4.0 installed and a mysql server without the connector installed the application falls immediately. So to fix the issue I install the mysql connector MSI.
This immediately fixes the issue on the client system and it runs. The problems is that as you can see below from my Installer setup that the 2 needed DLL files for MYSQL are actually included in the installation package so should not need to be installed separately. So Why is it that using that installer from the images do I need to install the mysql connector? Any Ideas?
Below is a screen shot of the References the program uses and from what I believe I do not need to deploy any of those DLL files with my application other than the 2 MYSQL DLL files. So why is this failing? Below are images showing the project references as well as the Installer Files that are being installed in the application folder. As shown in the image the 2 mysql dll files are to be put in the application folder. There is also a screen shot showing each dll's properties for in application folder.
How do I add new reference "Imports Microsoft.mshtml"? I go to "Project" and "Add Reference..." but it's not there.

View 8 RepliesI'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:

And then it shows me that my code for

Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.

I made a program a month ago and i gave it to the customers.recently they report some bugs and i fixed them. when i send the new version installer to them, they have some problems running it.i used vs 2008 to write it, but i removed vs 2008 and installed vs 2010 last week. when i opened my project to start fixing program bugs it asked for convert wizard so i did it.i made changes and build it. i use installshield and i add framework 3.5 Sp1 as prerequisites.
note : i was using inno setup first time. so i changed the installer too.so i tried installing the program on my machine.i just noticed that i have only .net framework 4 installed my own system. so i have no idea how the program runs without any problems on my own system. i have even tried installing it on another machine who had framework 3.5. it it work on that too.the error shown on customers machines is related to framework version. everytime i send them a new version they have some problem installing/running it.
I need to export data into an Access database. My code works, but it works with the assumption the client machine has the Microsoft.Jet.OLEDB.4.0 as a valid provider.
I want to test to see if this is true or not, in code. My problem is that I don't have the location of an existing access database and I don't want to create a new .mdb that I'd use to verify the connection and then delete it.
this is my code for adding users in my database but it has an error on the INSERT INTO statement.here is the error: Microsoft office access database engine: syntax error in INSERT INTO statement.

We have a VB 2008 Windows application that is deployed on several hundred computers. For some strange reason only 2 computers out of the hundreds are experiencing the "Error creating Window handle" error. It is happening more consistantly on one machine than the other. Any idea what might be causing annoying error on such a limited basis? (It's a Windows XP machine that it is happening on. That's all the info I know regarding the machine currently.)

If I build the solution on a machine that HAS a license for ActiveReport then everything is fine. If I build the solution on a machine that DOESN'T have a license for ActiveReport I get:
Error 1 'Could not load file or assembly 'ActiveReports6,

On the machine that DOESN'T have a license for ActiveReport if I remove the above lines from the license.licx file then everything builds fine. I always thought that if the license couldn't be found then the unlicensed version will be used but it wouldn't kill the build. How do I get this solution to build on any machine whether it has a license or doesn't?
