View 5 RepliesI am running VS 2010 Professional and have a solution with 3 VB projects in it. I can open the forms in 2 of the projects just fine but if I try to open any of the forms in the 3rd project I get a message saying "There is no editor available for .....Form1.vb. Make sure the application for file type (.vb) is installed". Everything was working fine last month and I could open any of the forms.
Again the problem is limited to just the 1 project in the solution.
In a VS2010 solution I have a license.licx file that contains:
DataDynamics.ActiveReports.ActiveReport, ActiveReports6, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Web.WebViewer, ActiveReports.Web, Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff
DataDynamics.ActiveReports.Export.Pdf.PdfExport, ActiveReports.PdfExport, Version=6.1.2814.0, Culture=neutral,
[code]....
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,
Version=6.1.2814.0, Culture=neutral, PublicKeyToken=cc4967777c49a3ff'
or one of its dependencies. Operation is not supported. (Exception
from HRESULT: 0x80131515)' LC
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?

View 3 RepliesOne of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.

I have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.
View 1 RepliesI need a code for the open file dialog that if a file is not supported then a message box appears stating the error. This is my open file dialog code. [code] The message box pops up like it is suppose to, when you click ok the open file comes back up like it is suppose to. When you put in the correct file the message box comes back up again. Also the message pops up even if the correct file is put in the open file. but if you close the file dialog the image is where it is suppose to be.I believe the code for the public sub wrongfile is what is the problem. can some one look it over and let me know what changes are needed.

View 4 RepliesThis is my Errormessage:
Could not load file or assembly 'file:///C:Windowssystem32Rule.dll'. The system cannot find the file specified.
The problem is that the same exe works in my development environment but not on productive server. The program is a tool that should run as a Scheduled Task on Windows Server 2008. It consists of an exe, one so called Database.dll and the Rule.dll. The exe should load the Rule.dll dynamically in codebehind but it fails with the above error only when started from Task Scheduler. Why is it looking in System32 folder and not in the Application folder? Is it an UAC-issue?

if I want to open my vs2008 project, I get the error "Could not load file or assembly 'Microsoft Build Engine, Version=3.5.0.0, Culture=neutral, .... or one of its dependencies. The system can't find the specified file." Yesterday it has no problem and today I get this message. I have uninstalled nothing, I have net framework 3.5 and in the meantime 4.0 too, I use win 7 x64. I tried to repair the install of vs2008 with the dvd, no succes. what I should do to get this to work again? I don't want to reinstall win 7 (inkl. format the system drive).
EDIT: I checked the system with the net verify tool, and it comes out, that some dll-s in the assembly directory are missing. Now, I clean up all net framework on the system, then I will install the net framework 3.5 sp1 and let's see, whether it works or not.
EDIT 2: I even can't install the net framework 3.5 sp1. I downloaded the full pack from microsoft and if I click on it, nothing happens. Why?
EDIT 3: after reinstalling all vs2008 components and after running the net removal tool again, I wanted to install vs2008 back. And the install says: the net framework 3.5 (x64) is installed. I know, win 7 contains it. Then how the hell can I uninstall and reinstall the net framework 3.5??
Usually, when I create an application, all I need to do is copy the .exe file from the "inDebug" folder to run onto other machines.
But this time, I've got a 3rd party control. So, copying the .exe isn't good enough. I get a message as soon as the application loads "Could not load file or assembly ..."
I have added a "Setup and Deployment" to the project, but that still doesn't seem to include all of the files to the 3rd party control.
Because after successfully installing this application, the same error message is displayed "Could not load file or assembly ..."
how I can get this application to run on another machine without installing this 3rd party control first?

View 5 RepliesMy code is calling a COM component to retrieve data from a contact management product. That code works fine when called directly from my VB code. However, if I add a Progress dialog and run the SAME code via the BackgroundWorker, the COM component does not run. It generates an error: Object does not match target type. when attempting to access items from the COM component.
Also, if I run my application via a batch file that simply calls the application, the COM component does not run. In this case, it generates an exception as soon as the COM component is accessed in the code. I have posted questions to the COM component vendor but after several days have not gotten any responses. Someone told me I could not access COM objects on a thead, but the same BackgroundWorker code works when communicating with Outlook or Lotus Notes (which I believe are both COM).
