Well Mike, yes and no.
I've got the Runtime Callable Wrapper, and I can use it (still) from an ordinary console application, but I'm still getting those errors when I try to instantiate the object from within a web service.
I found out that when I just try to load the assembly directly using System.Reflection.Assembly.LoadFile(filename) it fails with the same error. But System.Reflection.Assembly.LoadFrom(filename) appears to work, as does System.Reflection.Assembly.ReflectionOnlyLoadFrom(filename).
When I use System.Security.Permissions.FileIOPermission to determine my ASPNET user's rights on the assembly DLL, it tells me I have full rights, so it's not a matter of file access.
And I pulled apart the reflection data to find that I'm depending only on mscorlib, which can't be the problem either.
I finally tried signing my RCW assembly just in case it was ASPNET not wanting to run unsigned code.
So... it looks my specific question is: what is it about the ASPNET environment that makes loading a RCW assembly (or any assembly?) so different from a console environment? Is there a document that addresses that?
Thanks to all.

Hi,
I have a problem to make a CAB file for my project exe (create in Visual studio 2005, C#) into PocketPc 2003. When i execute a cab on a PDa with pocketpc 2003 I retrive an error: "It's not a valid CAB file for windows CE".
The CAB work perfectly on PDA with windows mobile 5.0.
Why? I can create a CAB file compatible with pocketpc2003?
Thanks a lot.
Alex

i wanna know that Application.Run only takes only from objects as a parameter like
Application.Run (new MYfrm1);
OR it can also take parameter other than windows form like Class Objects?

Hello,
I have this piece of code which i am using in my application developed on VS2003. i have migrated the code to VS2005 and have cleaned the code, but now i have to port it to Vista.
The code uses SHFILEOPSTRUCT and SHFileOperation which are nwo deprecated and a new interface IFileOperation has been introduced for Vista. I did a lot of head banging but still i could not figure out how to modify my code except the use of SetOperationFlag() function of IFileInterface. So please see if you could help.
Here are the snippets
<br />
SHFILEOPSTRUCT shfileop;<br />
<br />
shfileop.hwnd = NULL;<br />
<br />
shfileop.wFunc = FO_DELETE;<br />
<br />
shfileop.pFrom = pstrfrom;<br />
<br />
shfileop.pTo = NULL;<br />
<br />
shfileop.fFlags = FOF_NOCONFIRMATION;<br />
<br />
shfileop.fAnyOperationsAborted = 0;<br />
<br />
shfileop.hNameMappings = 0;<br />
<br />
shfileop.lpszProgressTitle = 0;<br />
<br />
SHFileOperation(&shfileop);
I get the pFrom and pTo from LPCTSTR type strings. I would also like to know about the double null termination of strings.
Thanks and regards,
Mustanseer

SHFileOperation is deprecated, not removed. Deprecation simply means that they have added a new method which they advise is used in future, and that they might remove the old way in future operating systems. However, IFileOperation is not available before Windows Vista which means that if you need to support older operating systems, SHFileOperation is the best choice.
The double null-termination is because SHFileOperation can work on a queue of items, not just a single item. Each item is a normal null-delimited string, and the queue is represented by all the item strings concatenated together. The end of the list is marked by an empty string, i.e. a single null character. To remove a single item, therefore, you pass the string (null-terminated) followed by another null, so it appears to be double-null-terminated.
Example: you want to delete items Item 1 and Item 2. Therefore you specify the string
Item 1<NUL>Item 2<NUL><NUL> I have to admit, I can't see how you get hold of an IFileOperation pointer. They seem to have forgotten to document that.

Hi Mike,
I agree SHFileOperation is deprecated but i wish to replace it with Vista compatible interface. the new version of my application is concerned only with running on Vista and later versions. i have got the idea of how to modify the code for copying, moving etc. but pertaining to deletion i am yet unenlightened.
Also, there is one more problem that i am facing. The new IFileOperation interface is placed in an Interface Definition Language file named "ShObjIdl.idl". i don't know how to import this file into my program to support the interface.
This is where i relate to you that how to get hold of the IFileOperation pointer.
PS: I am running my code on Vista currently and trying to debug.
Thanks and regards

what is the use of PDB files on dotnet. i am developing a profiling application
shall i use the pdb file to point the exact code?
My small attempt...
|
|
|
|
|
|
as i said i am developing a profiling application.
in that i want to display the exact code using the pdb.
My small attempt...
|
|
|
|
|
Sorry about that, I guess I read too fast. I think the pdb won't do what you need though. The pdb file is basically used by the debugger to attach/link to its corresponding application. In the case of profiling, I've read before that .Net has a Profiling API.

|
|
|
|
i just used that, but in the case of user defined methods i want to point out the exact code
suppose i have a method "SayHello()" in my app, after profiling that will show
classname SayHello() 0.0000002(sec)
This is done successfully, now i want to display the exact code inside the method "SayHello{}"
My small attempt...
|
|
|
|
|
As the code is run from IL, you can reverse it back into a version of the original (in the same way that Reflector does).
|
|
|
|
|
assemblin and disassemblin i already did.
as i said now i want to diplay the exact code.
Can we use PDB for that? to display the code
My small attempt...
|
|
|
|
|
Yes the PDB file is the mapping between the IL code and the source file.
|
|
|
|
|
Yes, you can use the pdb file. The magic word here is the ISymbolReader.
See this discussion here[^]
|
|
|
|
|
if i am having the source code file with me, can i display the source code using the line info from pdb?
how can i do that?
My small attempt...
|
|
|
|
|
I guess you can do that, at least the article I linked in does mention it.
You'll have to do the research, but since you writing a profiling app that shouldn't be so hard for you.
Most of the time you'll get directions here, not complete solutions.

i know i know anyway i will continue the same will post if i get any info 
My small attempt...
|
|
|
|
|
I just delete them. 
|
|
|
|
|
no problem it will generate when you start the app from IDE
My small attempt...

As you see, whenever installing an new software, you must have a license number to register your application.
Now, i have assigned to do that license part in my task but i don't know how to generate a license num or how to make a license checker professionally (in C#). So, anybody can help me this?
|
|
|
|
|
Well, no-one is going to tell you how they make THEIR license keys, b/c that would let you generate your own. There's all sorts of ways to do it, the simplest is probably a variation on hashing the username, perhaps salting it first.
