Hi to all



I am asking a very stupid question.

I have created a dll called string2.dll using Binary Compatibility  

I tested it is working fine.

Now I modified the code by  2 lines 

How do I recompile string2.dll using Binary Compatibility  ?



If I do by File -- Make string2.dll.

I get an error permission denied 

This dll is used as an component in COM+ (windows 2000).





How do I recompile string2.dll 



Thanks in advance

you have to stop the package in COM+, then remove the component from COM+, you can

leave the package there, but it will not contain your component.  Then, recompile

your dll, then add it back to the COM+ package.



tedious process, but it works and ensures no old version are hanging around in COM+.



hope this helps,



john

I'm not sure about this answer (I've haven't worked with COM+) but...



You might try shutting down all web services and closing interdev if you use

it.  Both will lock the DLL and cause that error.  Once services and apps

that lock it are unloaded, you should be able to recompile.  Compatibility

shouldn't make a difference.



One thing I have noticed when making DLLs. If you have a project group with

the DLL as one and a test project as the other, double check the test

project reference to the DLL. If it's referencing the DLL FILE (vs the DLL

Project) VB itself will lock the DLL and you can't recompile.



If the DLL is in MTS, I believe you don't have this problem. You can just

rebuild the component and MTS handles the details. Haven't actually worked

with this myself though.



Good luck.



Peter

Thanks in advance

if you change the interface (getters/setters/public methods) you will have 

to remove it form the package



but if you only change the implementation of the interface, and not the 

interface itself (code within the methods, etc..) then you shouldnt need to 

remove it from the package, only right-click the package, shut down.  and 

then just rebuild the dll



if you still have problems on the second instance, do the first.

I think you unregister first before compiling again

This is a good question.   I thought that Quang Tran

was right - you need to unregister (unregsvr /u

<path>) the dll before recompiling.  If you don't,

won't it create multiple GUIDs in the registry

referencing the same path to a dll?  Any other

thoughts?

Craig Shields

Move you DLL inside an MTS / COM+ package:



This is easier than it sounds:



Here's how to do it (I'll describe it for Win 2K, but it's about the same 

for NT4)



1. Open up COM+ Services in Start | Programs | Administrator Tools (It's 

called MTS in NT 4)

2. Expand Component Services | Computers | My computer

3. Expand COM+ applications

4. Right click COM+ applications and choose New | Application

5. Click next and choose "Empty application"

6. Enter a (arbitrary) name and click next

7. Enter the details for a user account you want the component to run 

under. Leaving it to interactive can be dangerous. Suppose somebody without 

rights logs in, then your component will no longer work. It's better to 

specify a user you created for this purpose with just enough rights..

8. Click finish

9. Expand your newly created package and right click Components and choose 

New | Component

10. Click Next, then choose "Install new components"

11. Click add and browse for your DLL

12 Click next again and click finish.



Now your component is inside a package, which you can easily shutdown. When 

you have compiled your DLL and tested it in your ASP page it will be 

locked. Simply return to COM+ Services, right click the package (with the 

name you gave in step 6) and choose Shut down. This will release the lock 

on your DLL and you can recompile it again.



Even then, the DLL might still be locked every now and then. This can be 

caused by Visual Interdev. Whenever you invoke the Intelli Sense dropdown 

on a component, in an ASP page Interdev locks the DLL. In that case, simply 

close the ASP page and recompile.



Using this method will save you lots of time. Shutting down an MTS / COM+ 

package is a matter of seconds, while on slower machines, restarting IIS 

can take up to several minutes. Besides, on a (semi) production machine, 

not your complete webserver goes down, but only the current package.



When ever you make changes to the interface of your component, you have to 

reinstall the package. However, this is likely to happen way less frequent 

than recompiling.

If you are using COM+ services in Win2K you do not have to register your

dlls, you just add it as a new component

when you want to recompile your dll you just stop your application, in com+,

you replace your dll and thatīs it.
