My question is related with VBScript.
But i didn't saw any topic with that one.
I have a small problem with a script.
Used this command : ret=objShell.run (strCommand ,0 ,true). Where strCommand runs 7-zip to do an archive. The problem appears if some files are in use by another process. 7-zip return and error code and the program stops there. I want the program to continue the execution because even with this error.
If I put the last parameter false the problem is that that the program doesn't wait for the archive to be done.
I looked for some hours on the net but didn't find anything so I'm a little desperate.
I really appreciate any help,
Thanks

The problem is with 7-zip rather than the VBScript.
check the parameters that are available for 7-zip. I suspect that 7-zip has encountered an open file and aborted, rather than continue on to the next file to compress.

no, he continue to compress the files and when he finish he throw this warning.
But the shell.run function see that the return code isn't 0 and suspend the program util I close the windows that 7-zip opened.

YOu should use Path.Combine, not string mashing blindly. I guess the file is not there  Have you tried debugging ?

Hello friends,
1)I've created one VB.NET dll.
2)I've created the .tlb file of this dll to use it in VB 6.0.
3)I am able to add the refrence of this .tlb file in the applicaiton.
But when I want to create the object of the class of this library using new method the library created in VB.NET doens't even appear in the list to create the object.
The code of VB.NET dll is as below.
Imports System<br />
Imports System.Reflection<br />
Imports System.Runtime.InteropServices<br />
<br />
<Assembly: AssemblyKeyFile("mykey.snk")> <br />
<br />
<ComVisible(True)> _<br />
Public Interface IAClass<br />
Function GetCurrentTime() As String<br />
End Interface<br />
<br />
<ProgId("MyCompany.MyLib.AClass")> _<br />
Public Class AClass<br />
Implements IAClass<br />
<br />
Public Function GetCurrentTime() As String Implements IAClass.GetCurrentTime<br />
Return System.DateTime.Now.ToString()<br />
End Function<br />
End Class
I've created the .tlb file from this dll.
The code of the VB 6.0 Application is as below.
Dim ob As SampLib.IAClass<br />
Private Sub Command1_Click()<br />
Set ob = CreateObject("SampLib.IAClass")<br />
MsgBox ob.GetCurrentTime<br />
End Sub
Please if anybody can tell what is the reason that doesn't allow me to use the .tlb file in VB.
Thanks in Advance to all of you.

Hey frnds. Suppose Combo1 contains data ,I want that when we click on
buton & alll the items are copied to Combo2.
Plz reply.
Thx in advance.

Iterate through Combobox1's items using for each ... next and add every item to Combobox2 using Combobox2.items.add(yourItem). Now, how difficult was that?
Are the keys "i" "e" and "a" broken on your keyboard?

Download the Merge Modules from BusinessObjects.com and include them in your setup/installer

Hi All,
I'm Alessio.
I have a problem.
I've got a simple DLL written in VB6 to wrap Outlook 10 objects and to access an Exchange mailbox via MAPI.
I've referenced that DLL into my VB.NET project and, if it runs onto my pc, it works fine.
Once deployed onto the real server, I get "QueryInterface for interface CustomMAPI._cCustomMAPI failed" message when my .NET app tries to create a "CustomMAPI" object.
I built a vb6 setup package, then I've copied every single DLL, OCX & TLB file from "<my pc="">\support" folder to "<real server="">\windows\system32" folder, but it wasn't enough.
So, now, I don't know what else to do.
Please, help me.
Thanx in advance and excuse me for my english.
Alessio

Background:
I'm making a program to read from smartcards (and write to it)
Setup:
I have a form (with only a richtextbox on it)
And 1 or more threads (with the form thread it's 2 or more) (every smartcardreader attached to the pc get's a seperate thread)
Problem:
I need to be able to set a variable (boolean or other) across all the threads
I have a class witch handles the code for detecting a smartcard inserted or removed and raises an event (witch I catch in my form and thru delegates put something in the textbox)
But as long as my form is processing the card (reading from it and getting user input) the other cardreaders have to wait and can't raise the inserted event.
To this end I thought I only had to declare a public shared variable and set its value (so I could check that in the carddetection code and if needed wait) (I know this is so in java (from my collage days))
Everything I read says that when I declare the variable shared it should be changed in all thread's however when I implement this I find that every thread has his own instance of the variable and one thread can't change the other
Anyone know how I could set a variable across all threads (so from the form thread or from 1 of the created threats for the readers)?
Any help would be appriciated
If my help was helpfull let me know, if not let me know why.
The only way we learn is by making mistakes.

Hi,
I'm afraid you are confusing a couple of things.
1.
the Shared keyword in VB.NET indicates a variable is a class member, rather than an
instance member, i.e. it exists once in the class, as opposed to once in every instance
of that class. The C# equivalent is "static". It has no relationship with threads.
2.
all variables by default are thread-agnostic, they exist once and are readable by all
threads.
3.
The one problem you may have is that variables could get "cached" in local variables
(that requires explicit code to do it) or in CPU registers, which could result in one
of the threads using stale data, i.e. not accessing the memory-based variable every time
your code seems to indicate.Example (in C#):
int a=1;
for (int i=0; i< 10; i++) {
int b=a+1;
}
although the code seems to access variable a over and over, maybe it gets executed
as a single read of a, and the value gets stored somewhere (in a register).
The compiler is allowed to do that under some circumstances, and there are ways to
prevent it. Good old C had the volatile keyword to prevent such optimisations;
C# has the same volatile keyword.
According to ms-help://MS.VSCC.v90/MS.msdnexpress.v90.en/dv_vsref/html/7c0efba1-45d9-4798-9051-9bdca3b899a6.htm VB.NET does not have an equivalent.
4.
There are language-specific keywords and thread synchronization primitives/classes
that may help you in achieving what you need. Have a look at SyncLock (that should do it),
and Interlocked class.
same.
