IDE :: Visual Studio 2010 Reference Path To Local Assembly Won't Change?
Jul 20, 2010We have upgraded our project from Visual Studio 2008 to Visual Studio 2010 without any issues until now. Our project contains a folder call Libraries which contains different versions of Oracle ODP.NET DLL's as well as different versions of Telerik DLL's. Our project contains references to one of the versions of each. The problem is once we remove the reference and re-add it by browsing to the new version, again inside the Libraries folder inside the project, it adds the reference, but to the same version we just removed. We can even copy the DLL to our desktop, remove the reference and add to the new one on our desktop and it still will point to the Libraries folder version???. The only we we can actual change the reference to the new DLL is by manually changing the path in the .vbproj file, which is obviously not going to work for us. The same behaviour worked perfectly in VS 2008. We switch our references quite often, when new versions come out, but also far more often to QA different versions of ODP.NET and Telerik Control DLL's, so manually editing the .vbproj file is becoming quickly cumbersome. If I browse to a specific version at a specific path, Visual Studio should ALWAYS do what I'm telling it to do..
I did some seaching and came across a few other people with the same issue. This better not be as designed and if it's a bug, which I believe it to be, when will it be fixed?[URL]..
Reference A Dll With Copy Local = False
May 28, 2009I have a VB.NET project which references a dll of another program. dll file location is something like "C:Program FilesAppNameAppName.dll" and on my project's references tab the dll's path shows this. When the copy local property is true, everythings works fine. When it is false, I get a runtime error saying dll cannot be found. The other program is a restricted access application and I can not distribute the dll with my project. How can I force my project to look for dll under "C:ProgramFilesAppName"? I didn't have this issue with VB6.0.
View 8 RepliesDefaulting A Reference's Copy Local To False?
Jan 11, 2010Is there a way to default the Copy Local property of references that I add to my projects? I figure there has to be some sort of method since adding a reference to a VB componentdefaults to False. (for example, start a project as a class library and then adda reference to System.Windows.Forms, it will default Copy Local False.) Is that somethingin the DLL's settings or configuration that I could replicate in my DLLs to force that

Copy A File From A UNC Path To Local Destination?
Jun 21, 2010I want to copy a file from a UNC path (ex: \comnamedirnamefilename.txt) to a local destination (c:outputdir)
I have no compile errors, but when I run it, it throws an exception (System.IO.DirectoryNotFoundException). I'm absolutely sure the destination existst (it's referencing the destination directory). I've tried doing it with system.io.file.copy(source,dest)and my.computer.filesystem.copyfile(source,dest). Same result either way.
Process.Start - Reference To The Local File
May 16, 2012I have an application that that uses process.start. It works fine on my development machine...but not on an installed machine....at least not for a local file. The following illustrates my problem...the reference to the url works fine and every time. However, the reference to the local file may work the First time but on any following attempts will close the application with a WindowsApplication1 error. Since it can find the file occasionally it is not a file problem.

.net - Don't Create Local Variable To Hold The Reference Of The Object?
Nov 17, 2010How does the GC dispose objects created in the following 2 scenarios?
1)
Private Function DoSomething() As Boolean
Return New DatabaseManager().Insert()
End Function
2)
Private Function DoSomething() As Boolean
Dim mngr As New DatabaseManager()
Return mngr.Insert()
End Function
In Option 1, I don't create local variable to hold the reference of the object. In Option 2, I hold the reference in local variable.What option is better and why? (if any)
COM Dll Reference Path Is Missing?
Apr 12, 2010Using VB.NET 2008 SP1 on Windows XP Pro SP3:
I am using an existing COM dll that works fine in VB6, on the same development machine. The VB6 app compiles and uses this dll without issue.
I start from scratch to design a new Windows Form application in VB.Net. Then when I try to add a reference to this dll, the reference is added to the references list but the path shows as <The system cannot find the reference specified>. If I select this reference in the list, the properties window shows a blank for both the reference name and the path. At the same time, a reference is added for VBA, and it shows the reference name (Interop.VBA) and path correctly.
I used dependencywalker to find the dependencies for this dll. It has 3: user32.dll, kernel32.dll, and msvbvm60.dll. So presumably I have all necessary dependent files.
I have tried un-registering, re-registering the dll. I have tried the command line switches for devenv.exe to reset settings and to launch in safe mode. I created a new user account to see if it was related.
I have tried picking the dll from the Add References, COM tab and also via the Browse tab to select the file directly. Same result all cases. I also tried putting the dll and msvbvm60.dll in my bin folder.
I don't understand how the reference name and path are missing in the properties window when the reference name is right there in the list and I select the path directly when I added it. There are no other instances of this dll registered.
I tried using tlbimp from the command prompt with verbose switch, I get the error:
System.Runtime.InteropServices.COMException - Error loading library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRAY)). I wish it would tell us what is missing.
It must be registered properly and all dependencies available for it to work in my VB6 app, Re-writing the dll is not currently an option.
Compiling Path And Reference
Sep 2, 2009Suppose I have a solution containing several projects. I set the compiling path as ..in folder. A reference file xxx.dll is used in project aaa, yyy.dll is used in project bbb etc.
xxx.dll and yyy.dll are stored in c:sharedlls folder.
My question is that if I compile the entire solution, do xxx.dll and yyy.dll are draged into ..in folder automatelly?
I am not clear the purpose of the compiling of the solution exactly.

VS 2008 Reference And Build Path
Jul 30, 2009Suppose in a solution there are two projects A and B. A is a class library project, B is a console project. I set the output path of project A as ..in elease, after I compiled it, I found it is ture that a created file testA.dll is there. Just curiously I checked the folder ..indebug, it is empty. Likewise, I set the output path of project B as ..in
elease. Okay, then I add the file testA.dll to the project B and run the solution etc..
My question is that after these procedures, I found that testA.dll is also in the ..indebug of project A. And also when I checked the folder ..indebug of B, testA.dll is there as well but nothing in the ..in elease of B. I just want to know the secrets of the build path, I am always confused in the real world because there are several projects in a solution.
Copy Value Of A Reference Type?
Jan 12, 2010I've got a class, lets call it Person, which needs to keep some data (in the form of another class which we will call PersonData) in one of its properties - the problem is that I will have several instances of this person class and they all need their own 'copy' of the data (just in memory, its not a file or anything).Hhow would I do this? At the moment because everything involved is a Reference type, I'm assuming that if I were to create 2 instances of my Person classes and assign the same instance of the PersonData class to their properties then when one Person class made a change to the PersonData it would be reflected in the other Person class right? How can I avoid that and make it so that they both have their own version of the data, without having to repeat the procedure that fetches the data in the first place?
I'll explain my exact situation just in case it helps, but this is more of a general question as I could probably get around it in this case by copying the byte array I receive from the server (hopefully that will make sense once you read the explanation below) :
In this case the data I am talking about copying is actually received from a server via TcpClient. The thing is, when the client requests the data from the server over the network, the server has to go off and query several other servers etc so I do not want to be requesting data from the server every single time as that would be a big waste of resources and time. So when a request is made and data is received back from the server, several of these Person class instances will be created (in reality, its a few different classes but that doesnt make a difference for this example) and each need to have access to the full data that the server has sent back but in some cases the Person instances might need to modify the data and this is where the problem appears as they will all be working on the same data.

Feb 1, 2010How can I search the local disk for a file type and copy the full path to a new location. I am trying to write a backup program that will copy all pst files to the server while maitaining the structure, so if there is a pst located in "C:pstuserpersonal1.pst" it would create the folder "\serverpstuserpersonal1.pst" and copy the file to the correct location. I would need it to do this for each pst on the hard drive no matter the location. The user running the program will not have admin rights, so it will need to skip files it cannot access.

View 2 RepliesAdd Object To Collection (copy Not Reference)?
Mar 27, 2009i have a user define object which i'm initializing with data from external datafiles.... the purpose of this object is to reduce the amount of disk/data access and processing required every time i need to add an instance of this object to a collection.so, whenever i add a copy of this object to a collection, i would simply reference the "base" object, and avoid having to process all the data and perform the conversion and so on...the issue is when i add the object
Collection.add(Base_Object, Key)
the collection ITEM is a Reference to the base object and not a copy.
Copy Reference Resources On Compile?
Oct 29, 2008Lets assume that I code a DLL in .Net and I've added some items to the project (For example a picture, or an XML file that contains some kind of configuration for the DLL), and I set the "Copy to output directory" to be "Copy Always".
Now, what I wanted is that if I give my compiled DLL with the bunch of files that were added as items to it, then if someone ads a reference to the DLL in his project then on compile it will copy all files and not just the DLL.
Is it even possible (Some kind of configuration on Visual Studio maybe)?

Dec 7, 2010I am opening frmB (variable for FormB - the actual form) from frmA. From btn1 I open frmB like this:
frmB = New FormB()
frmB.Show()
From btn2 (frmB is already open) I bring frmB to the front from behind frmA:
FormB.Show()
FormB.BringToFront().
No problem so far. Now I need to pass an arg to frmB. This is where I am having the problem.
from btn1 (in frmA) I do this:
frmB = New FormB(myArg) '--pass myArg to constructor of FormB -- no problem here
frmB.Show()
then from btn2 -- this is where I have the problem
FormB.Show()
FormB.BringToFront()
I tried placing myArg in FormB.Show(myArg) but that did not fix the problem. What is the correct way to pass myArg to FormB (frmB) in this scenario? Do I need to share FormB or frmB? How do I do this? "frmB" is frmA level variable.
