A Customer of mine has a Problem with my in vb.net developed extension in ArcMap. The extension is installed on a Windows 8.1 with ArcMap 10.3. First it worked fine, but now (since one week) there comes an error from the 'System.Transactions.Diagnostics.DiagnosticTrace' when the extension try to connect via oledb with an access db (personal geodatabase). The strange thing is, that the stand alone app (without ArcMap) has no problems to connect (and it uses the same oledb object). Does anyone have a clou what can cause the problem? thanks a lot.
I solved it. The problem was a brocken config-file (user.config) in the user-account (C:\Users\\AppData\Local\ESRI\DefaultDomain_Path_...\).

I've written a program in VBA (not excel) to upload data to a PostgreSQL database using ADODB via a DSN. Often it works without a problem, but sometimes I get a "Specified driver could not be loaded due to system error 127" error. When I get this error, I've found that the only solution is to restart my machine (which acts as both the client and the server in this case).
I've tried modifying the DSN to use either 32-bit or 64-bit, but that hasn't helped. When the error occurs, I've tried restarting the PostgreSQL service, but that hasn't helped either.
I've googled for solutions, but nothing seems to help.
I'm hoping for some solutions to either resolve the problem or offer an alternative to this method that bypasses the problem - any suggestions would be great.
Happy to share code if it helps, but it's all simple tutorial level stuff.
I'm having a massive problem trying to write a file into the c:\windows\system32 directory. The code works fine on 32 bit machines, however does not work on 64 bit machines.
My user account is an administrator on the machine, and even right clicking and choosing to run the app as administrator does not solve the issue.
When writing the file, no exception is thrown, but the file is not written.
I have read various posts regarding adding an app.manifest file containing the requestedExecutionLevel node to my solution, but as yet am unable to get this to work. I have a feeling this may be because I'm using vb.net rather than c#.net
Has anybody encountered this issue before? I'd be delighted if somebody could provide an example VS2010 VB.Net project with a correctly configured app.manifest file as I'm a little unsure whether my attempts at setting this up are correct.
(also, this is not a malicious app I am writing, I'm working on a version control app for our team and need to be able to interface with IIS files held in c:\windows\system32\inetsrv\config).
Thanks
David
Maybe the file is written under UAC Virtualization and located under C:\Users\Username\AppData\Local\VirtualStore\Windows\System32

Under Local Sercurity Policies there is the following option which controls UAC Virtualization.
I installed Microsoft SharePoint and Project PWA on Windows Server 2008 R2.
When I want to open Library in Windows Explorer, I randomly get an error:
Your client does not support opening this list with Windows Explorer
When I open IE it's working for 1st and 2nd time, but after some clicks it's not working anymore and I need to restart IE and then it normally works for couple of times.
When it not working through Sharepoint it also not works via \server\DavWWWRoot\PWA and oposite.
I'm searching through the web for weeks and didn't find any solution.
Do you have any idea what should be wrong here. Any suggestion is welcome :)
I had the same exact issue with Windows 7 and explorer view. The following steps resolved the issue for me:
First - be sure that the Web Client service is running (run>services.msc).
Next - In I.E. check Tools>Internet Options>Security>Local Intranet>Sites>Advanced and add the site that you want to use explorer view with.
This finally fixed it for me. I hope that you have already found a solution to this issue! I was surprised at how difficult it was to find a solution to this problem!
This error message is a symptom to a billion different problems.
I solved this problem when I realized my XP32 box could do this just fine with IE8. So I reverted to IE8 in 7x64 (you have to do it by uninstalling updates for IE until you're back at 8) and it didn't work. The build versions were different and on the 7x64 "about" box it said IE8 was using 256-bit cipher while in XP32 it had 128-bit. That to me was a hint that there may be 64-bit issues even when you run the 32-bit executable.
Then I found this hotfix so I reinstalled the windows update for IE10 and then installed this hotfix. Now I'm able to open the TeamCenter site in question in windows Explorer. IE10 reports it's version 10.0.9200.16686. I cannot guarantee that it was the hotfix alone (and not also the reinstallation of IE10) which fixed it. But I'm willing to bet it was the hotfix alone.
In XP I found it impossible to then map this network location to a drive letter, as mapping doesn't like URL's. However in Windows 7 you can transform the URL so that it is interpreted as a Windows share. If the URL of a given folder is of this form:
https://somesharepoint.com/folder1/folder2/folder3
you can also access it as
\\somesharepoint.com#SSL\DavWWWRoot\folder1\folder2\folder3
and, in this form, it can be mapped to a drive letter.
I do have issues at that point that even with IE10 open and logged in to the site I see some random time-out like problems and I get kicked off (and prompted to log in again in IE10). My situation is complicated because the site I'm accessing requires an Exostar token to log in, so I have to log in via website no matter what.
If it helps any one do the steps suggested above:
Make sure to use 32 bit internet explorer (program files (x86)/internet explorer).
Like was mentioned above Web client must be started.
You may also need to add your site to trusted sites in internet explorer.
Make sure enabled protected mode in internet options is disabled.
This is what finally fixed it for me: Check "Keep me signed in" on the login page. This was the key for me. Will not work without it checked in my case.
I had the same symptoms, and it turned out I don't have a root site collection. Creating one solved this for me.
Summarized the troubleshooting steps here:
http://letitknow.wordpress.com/2012/07/22/your-client-does-not-support-opening-this-list-with-windows-explorer-error/
There can be multiple reasons for it.
One could be using IE x64 version. It won't work there.
Secondly, check out this blog:

I experienced the same problem as well.
And I found out that if none of the above options are working, and if you work in an organisation, maybe the proxy is blocking the "Open with Explorer" option.
I did the same, and removed the proxy and it worked just fine.
this fixed it for me ( however in windows server 2008 you may need to install desktop experience i think its called)
After you log into windows go into services then restart the WebClient then see if you can use explorer view without the error " your client does not support. blah blah blah" if it does work then. make a batch file that says:
net stop webclient
net start webclient
then make a scheduled tasks that runs that batch file at start up. Have it run as a user with administrative rights, make sure you tell it to run even if user is not logged in. it should prompt you for the password of the admin account you selected. this worked for me with windows 7.
I found online where the error can occur intermittently with SharePoint 2010, however I think the SharePoint version is irrelevant. They said the client polls for a SharePoint root site and that the error occurs if one isn't found.
We have not seen the error since I created a root site even though we’re only using WSS3. Our errors began when we changed clients to Windows 7. So in our case it sounds like the issue could be the root site polling due to an IE8 security change in Windows 7.
SOLUTION:
*you on x64 bit machine* so solution is that there is no problem but you are using the wrong IE shortcut.
There are different IE types you can use (just type Internet Explorer in start search bar) and you will see..
Internet Explorer (64-bit) - won't show any sharepoint add-ons
Internet Explorer (No Add-ons) - won't show any sharepoint add-ons
Internet Explorer - only this will show sharepoint add-ons and will
work so basically make sure you always use this version of IE
I just can't get MAPI to work on our production machines. I've already created an application that uses MAPI and sites on that very machine but for some reason I can get my new app to work. I have no idea what I'm doing wrong.
Locally I've created an application that uses MAPI to log into a mail profile and retrieve messages. The messages are parsed and moved to 2 different folders one for errors and one for competed message. This all works perfectly on my computer but fails to login in production.
I know This is not a permissions issue because I'm using the same profile/pwd that my previous application is using. I thinking it may have something to do with the version of CDO or MAPI on my computer compared to the one in production but I'm just not sure.
Does anybody have any ensign into what CDO/MAPI versions I should be using, if some version don't work with different versions of windows...etc?
Solved my own problem. Basically using MAPI in a MTA(Multi-Threaded Apartment) is bad news and should be avoided as much as possible. The problem I was having was do to running my MAPI code inside a MTA thread.
I've attempted just about everything to get our ClickOnce VB.NET app to run under Terminal Services as a RemoteApp. I have a batch file that runs the .application file for the app.
This works fine via RDP desktop session on the terminal server. As a TS RemoteApp, however, well... not so much.
I get a quick flash of command prompt (the batch file) on the client system and then... nothing...
Same goes for having it point to the .application file directly (without using a batch file) or even copying the publication locally and having it point to that.
I found a technet.microsoft.com discussion about a similar issue, but there's no resolution to it listed.
For anyone who has run into this before and got it working, what did you have to do?
We currently use RemoteApp's for everything else on that server, so I'm hoping to stick with that if possible.
The current workaround is to build and run an MSI-based installer for the app on our terminal server whenever we publish via OneClick out to the network, but this can be quite a pain at times and is easy to forget to do.
Since the app works fine via Terminal Services when run in full desktop mode but not during RemoteApp, I don't think it's anything specific to Terminal Server permissions so much as ClickOnce requiring something that isn't available when running as a RemoteApp.
The Key to getting it to work is to use Windows Explorer "C:\windows\explorer.exe". This process is the base process when you login to a full session.
If you setup the RemoteApp to use Windows Explorer and the command line argument of the path to the .application file for the ClickOnce application then it will work when launched as a remote application. Windows Explorer will flash for a second when it starts, but it will disappear then the ClickOnce application will launch.
Why does it have to be a ClickOnce application? I would consider just deploying the exe file and assemblies.
I know it only half a solution, but if the application does not change much, it might be a good solution.
I believe your problem is related to the fact that ClickOnce needs to store it's data in a special user folder called the ClickOnce application cache. Apparently because of how Terminal Services sets up user folders ClickOnce can't access this in TerminalServices mode.

There may not be a way to do it :(
Can you launch the .exe directly? It's buried under your profile in \AppData\Local\Apps\2.0[obfuscated folders], but you should be able to find it.
That will skip the built-in update process, but if it can be launched that way you could then write code to do a manual update after the application starts.
Faced the same problem this morning and got it resolved by copying the clickonce app's directory from the user settings folder to somewhere like c:\MyApp\ - I know its nasty and not very ideal.. but good enough for me!
We recently ran across this issue and decided to post a bug report on this issue to the Visual Studio development team. Feel free to comment on the bug report. It has to be a bug in ClickOnce caused by some changes in Server 2008.

We also have a discussion on the MSDN forums covering this issue:
http://social.msdn.microsoft.com/Forums/en-US/winformssetup/thread/7f41667d-287a-4157-be71-d408751358d9/#92a7e5d9-22b6-44ba-9346-ef87a3b85edc
Try using RegMon and FileMon when starting the app - You may be able to track it down to a file and/or registry permission issue.
Also maybe check the event logs to see if anything's getting logged when the process fails.
