Getting Runtime Error 3447 - Jet VBA File (VBAJET.dll For 16-bit Versions Or VBAJET32 For 32-bit Versions) Failed To Initialize When Called
Aug 19, 2010
To the board: Lately I've been getting Runtime error 3447 ("The Jet VBA file (VBAJET.dll for 16-bit versions, or VBAJET32 for 32-bit versions) failed to initialize when called. Try reinstalling the application that returned the error") when attempting to open a certain program (not one that I designed, just downloaded and installed). I installed this program in January 2009, but this error began happening only this past July. someone else to information about the files vbajet32.dll and expsrv.dll. One site said that the problem was probably caused by the file expsrv.dll being absent, but I checked my System32 folder, and it's there. As far as I can tell, it has always been there (the computer was made in 2008, and as I said the program had always worked before). Vbajet32.dll is also there. I tried uninstalling and reinstalling the program, but error 3447 still occurs. I also tried uninstalling the program and installing an older version, but 3447 is still there.
I tried replacing expsrv.dll, thinking it might have been corrupt, but that didn't help, and I cannot register that dll anyway. I can't figure this thing out. Both of the files are there, and I didn't change any settings or anything anywhere between last January and this July. By the way, I am on Vista.

VS2008 / XP Pro sp3 / .NET 3.5 I develop during the day on my office computer and bring home projects on a laptop to work on over the weekend. After working at home then at work, I have a conflict that I don't understand. When I build, all is normal but when I debug, I get "Found conflicts between different versions of the same dependent assembly." If I click on the warning message I also get "Do you want to fix these conflicts by adding binding redirect records in the app.config file"?Both computers have same O/S, same SP, same .NET, same VS. Only thing that could be different is particular O/S updates that have been installed on each machine. What causes this warning and where do I look for differences? I really hate to let mSoft keep changing my code every Saturday and Monday. I just don't trust it on Mondays.

I've read about revising the File Version (and Assembly Version) to ensure that an updated file does replace an older/previous file when a WI update installation is carried out, but I don't understand the four-part construction of the File Version ... and my re-versioned files sometimes refuse to transfer to the target computer.
For example, a .exe I have recently updated had it's File Version set to 1.0.0.0 (it is resident now in my Program Files (x86)/MyApplication folder) and File Date 23/03/2012, but even now with the File Version set to 2.0.0.10 and a File Date of 24/03/2012 when I use WI to install the new program over the original the 1.0.0.0 file remains in place and the new 2.0.0.10 file does not get installed instead.

In VS2010 I'm encountering a PInvokeStackImbalance error when I call an unmanaged C function that takes a string argument. This only happens in VS2010 (works fine in earlier versions of vs). I know the MDA is more strict in VS2010 but I can't seem to figure out what the actual problem is.

I'm writing an Excel file recovery program with VB.Net that tries to be a convenient place to gather and access Microsoft's recommended methods. If your interested in my probably kludgy, error filled, and lacking enough cleanup code it's here: http:[url]..... The basic functionality seems to work although I haven't tested graph macro table recovery yet.
It occurred to me that Vista and Windows 7 users could benefit from being offered a list of previous versions of the file within my application if the Shadow Copy Service is on and there are previous copies. How do I do this?I looked at a lot of web pages but found no easy to crib code. One possibility I guess would be to use vssadmin via the shell but that is pretty cumbersome. I just want to display a dialogue box like the Previous Versions property sheet and allow users to pick one of the previous versions. I guess I could just display the previous version property sheet via the shell by programmatically invoking the context menu and the "Restore previous versions choice", however I also want to be able to offer the list for Vista Home Basic and Premium Users who don't have access to that tab even though apparently the previous versions still exist. Additionally if it possible I would like to offer XP users the same functionality although I'm pretty sure with XP only the System files are in the shadow copies.
I looked at MSDN on the Shadow Copy Service and went through all the pages, I also looked at AlphaVSS and AlphaFS and all the comments. I'm kind of guessing that I need to use AlphaVss and AlphFS and do the following?Find out the list of snapshots/restore points that exist on the computer.Mount those snapshots.Navigate in the mounted volumes to the Excel file the user wants to recover and make a list of those paths.With the list of paths handy, compare with some kind of diff program, the shadow copies of the files with the original.Pull out the youngest or oldest version (I don't think it matters) of those shadow copies that differ from the recovery target.List those versions of the files that are found to be different.This seems cumbersome and slow, but maybe is the fastest way to do things. I just need some confirmation that is the way to go now.

So i've coded a simple vb project in MS VB 2008. I then copied the contents of the 'bin/release' folder, and tried running the program on another machine. I'm getting 'the application failed to initialize' error. I'm assuming this is because i'm missing certain files, dll's or something. Or should I have copied the obj/release folder?

I'm trying to create a virtual piano using pictureboxes to represent keys that play .wav file versions of notes. I've gotten this to work fine; however, I'm having trouble with two features I want to implement.The first feature is to be able to save what I play in a text file. I thought I could use this code but I'm getting an error. [code] The second feature is to play random keys using the random class. Is there any way I could store the pictureboxes in an array and then use the random class?

I have a VS Solution with several projects. I want to set a specific project to the start project in Debug mode. Everything seems to run fine as I set breakpoints on the initial Form and several initialization procedures. At one point however, I get this error which is not an issue when I compile and run the release version.
Here is an illustration of the Exception. Unrecognized configuration section configuration. (C:...path...File.vshost.exe.config line 25) The config file is listed below an the jit debugging = true statement is on line 25

I've been having an error with my Visual Studio 2008 with .net framework 3.5 Sp1. I am creating a project, and it would run properly until after a while when I try debugging the project I would get a error message that says:
"Error while trying to run project: Could not load file or assembly 'Name_of_Project' or one of its dependencies. The module was expected to contain an assembly manifest."
Also the .exe file that it creates in the bindebug folder gives and error that says:
"The application failed to initialize properly (0xc000007b). Click OK to terminate the application."
These errors after a format of the machine would disappear for awhile but not indefinitely.

I unfortunately downloaded and installed Visual Studio 2010 and upgraded all my programs to .Net 4. I am really unhappy with the way 2010 runs. My computer keeps locking up for hours, programs take a long time to compile... Those are a couple of major issues.

I am developing a plugin into a third party control. They ship a SDK dll with their application to allow you to do this. However I am writing the plugin using version 1.1.0.0 of their SDK, but when trying to run the application on a clients machine that has a new version of the software the SDK version is 1.4.0.0 and my app throws the following error:
System.IO.FileLoadException: Could not load file or assembly 'MyDll.dll, Version=1.1.0.0, Culture=neutral, PublicKeyToken=764d581291d764f7' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
When the dll is referenced into Visual Studio I have changed the Specific Version property to false, however this has not made any difference. The dll is not reference from GAC.Is there a way that I can tell my application to just use the version of dll that is on the users machine? I have checked with the 3rd party vendor and the functionality that I am using has not changed in any of the versions as they use a back-ward compatibility approach to their software.

I have a dataset that I export to xml (using ds.WriteXml) and then use an instance of Microsoft.Office.Interop.Excel.Application to open and manipulate the xml data, then save it as an .XLS file.I have office 2007 (why don't they have help/about in an easy to find place... man I hate those stupid office ribbons and the person who developed them...)Anyway, this code works fine for me. But when I put this on a machine that has office 2003 installed, it crashes.So, what do I need to install, reference, buy, etc. so that I can do the same thing on machines that have 2003 (or before) installed? No, I can't install office 2003 (my first thought).

I have an application that uses a Microsoft DLL (Microsoft.ComponentStudio.ComponentPlatformImplementation.dll) which is used for OS deployment and accessing the catalog files. Version 6.0.0.0 is specific to the Windows Server 2008 catalog files. The newer version 6.1.0.0 is specific to Windows Server 2008 R2 catalog files. Attempting to access a catalog file with the incorrect version results in an exception.
My application (VB.NET using VS2005) needs to be able to access either version of these catalogs - I'd be happy with two executables (one for each catalog version) but obviously I don't want to maintain two sets of source code for each. Specifying both sets of DLLs in the project reference is not possible as the DLL names are identical. I'd rather not have to manually add and remove the DLL references each time I want to a build. As far as I know the interfaces etc are effectively identical between the two.

Any best practices on how to deal with different versions of base classes.We have made significant changes to the base class but still have lots of code inheriting from the old base class. Could you recommend how we introduce new base class.We'd like all new code to use the new base class. But, we would like the option to have old code still inherit from old base class so we have time to switch and test old classes with new base class.

know where I can get a list of the differences between VB.Net versions? For example, in which version were generics first introduced, and when did the "Using" keyword come into being?
I've tried googling it and all I seem to get are the differences between VB6 and VB.Net, which isn't what I'm after.

The application was developed with Excel 2000 but doesn't work with 2003 or 2007. The save isn't working. Everything I have googled shows this to be a common problem. I just haven't found a solution that works.

I work for an FDA regulated company, and they are obviously very particular about keeping track of any software changes. If I build a Windows application and then later wish to make a change to that application, does Visual Studio provide a way to save the source code for the old version of the app and the new version in separate locations?

I have a .net Application that writes text to a serial COM port, a POS reciept printer to be more exact. i am using the Rs232 class library to write and read to a serial device.My problem is now with some clients that have updated their operatingsystem to WIN7 64bit version, have trouble to create a connection to the COM-port. the com-port seemes to get occupied with some other process and that blocks my application to opening a new connection. so for my question, does anyone know how i can close all connections to a com port? or see whats blocking it? once again this seems to only to affect win7 and 64bit users.

I have a pretty complicated project with lots of class files, code modules, etc. There was a changed to one of my referenced DLLs that requires an isolated change in a single Sub within my solution. Unfortunately, this new Sub is not compatible with most of my clients' configuration but is required by some of my other clients. So now I must keep two versions in Source Safe of my solution - which I do not want to do. What I would like to do is to be able to determine which DLL is running and flip a switch to use the either the old Sub or the new Sub. Currently the sub is in a class, but I could break it out. Is it possible to determine which assembly version DLL is running? Also, if I reference the new DLL, the old Sub will not build. If I reference the old DLL, the new Sub will not build. So is there a way to keep both Subs in the same project?
Can I use reflection to know what is the assembly version of a loaded DLL?

ASP.NET pros out there can answer this question. I have a single web application that contains a website and a web service - both have several assembly references in common (data access layer, utilities, etc) - however, recent changes made to the web service will require different versions of the common assemblies, versions that the website won't work with (in case you're wondering, the website is some legacy 1.x .NET code that explodes when using the newer version assemblies.)
allow my web service to reference one version and have my website reference another? I can obviously have only one version with the same name within the bin folder.(P.S. - It just dawned on me that I could probably compile and reference the common assemblies with a different name, and place those in the web app's bin folder - but that sounds really fugly...)

The software I design is for Win XP and older versions such as Win 98, ME, 2000 etc. I currently use VB6 and Win XP for development and packaging, the problem I encounter is that if I use the deployment wizard in XP, the setup will only work on an XP machine and I need to copy all my source to an older machine and use the wizard again to create another setup file which will only work on the older operating systems. Is there a way to rectify this in VB6? If not, does the new VB account for this and be able to make a setup file for older operating systems as well as XP?

I am developing an application using VB.Net which is a simple executable which is to be run from a network drive of our company servers. Most users can access this executable without issue - others however can open the executable but have no connection to our database (even though when running the executable off a local drive such as C:, the database works no problem).
From some posts I have seen this might be a CAS issue - however our IT department suggest the issue might be down to different version of the .NET Framework being to blame. Firstly, is this the issue? Secondly, how can I develop my application to work with different versions of the .NET Framework? Surely this doesn't mean developing many different executables?
