Are you writing a backup service?
The reason applications can lock files, preventing other applications from reading the file, is that the file is most likely going to be in a state of flux. Any application that reads the file will not be able to determine if the file contents are safe or not because they are subject to change. You might read one part which is fine, then the next part which has changed and no longer makes sense when placed next to the first part.
Sameers (theAngrycodeR ) wrote: I must then read the file(s) which are even locked or in-use
I would suggest that makes for a bit of a dodgy backup. For example: SQL Server provides its own backup engine which creates a new file that is in a consistent state because you cannot safely perform a file backup directly from the filesystem.

You're only other option is to rewrite to code in VB. You can't use the C# code, without rewriting it, without compiling it into its own .DLL.
A single project cannot use more than one language, but a solution can contain multiple projects, each written in a different language.

Hummmmn, why dont you compile that C# code at runtime and use that in your VB class? Does that make sense?

What exactly are you looking to do? The .DLL is user32.
You're looking for the SystemParametersInfo[^] function.

Hello ,)
My Brother told me about this forum, so now i write my first post. Hello at all...
Now lets talk about my problem. Like i wrote in the subject, my wish is to exeute an shared member of an assembly.
I already load my needed assembly with the following code:
Dim lvAssembly As System.Reflection.Assembly
lvAssembly = System.Reflection.Assembly.LoadWithPartialName("MyAssembly")
But how can i now execute a shared function from this assembly? Lets say a function like this one:
Public Class MyClass
Shared Function WhatEver(ArgWhatEver As String, Arg2 As Object) As Boolean
...
End Function
End Class
Thanks for help and excuse my bad english, please ,)

First, you might want to rethink using this method for a while. At least until the next service pack for .NET 1.1.
A memory leak may occur when you run a .NET Framework 1.1 application that requires the Assembly.LoadWithPartialName() function to load an assembly[^]
I'v never done it, not have I even tried let alone compiled this, but you might be able to do something like:
Dim lvAssembly As Assembly = Assembly.LoadWithPartialName("MyAssembly")
Dim myType As Type = lvAssembly.GetType("FullyQual'ed.typeName")
myType.InvokeMember( _
' The name of the Method to invoke.
"myStaticMethod", _
' Binding flags for finding the method name in the Type,
' and what to do with it.
BindingFlags.DeclaredOnly Or BindingFlags.Public Or _
BindingFlags.Static Or BindingFlags.InvokeMethod, _
' Use the default Binder.
Nothing, _
' Object to invoke the method on.
' Since this is a static method, I don't think you have to put anything here,
' but I'm probably wrong.
Nothing, _
' An array of arguments to pass to the method, in order of their appearance
' in the method definition.
args)
You'll more than like have to modify this. I suggest reading up on Type.InvokeMember[^] for more information.

 What do you mean it worked???
Just kidding! I'm surprised because I wrote it from memory, from what I've seen in the documentation, not that I've actually used the code. I guess we all get lucky once in a while!

Hi in my code i need to use header file "intrins.h", but when i compiled its giving error "d:\nrf2401\fx2sdly.h(10) : fatal error C1083: Cannot open include file: 'intrins.h': No such file or directory",
i want to define the code of this header file. In keil user guide its given what kind of prototypes for routines that instruct the compiler to generate intrinsic code, but not given the code. How to add this header file in my program, and where can i get the code.
Thanking you all,
Nice start in new year.

I'm assuming you not cross-porting this question all over the forums...
You CAN'T include this in your VB/VB.NET app. SInce *.h files are C/C++ files, they will only work in those languages.
You have no choice but to rewrite the appropriate parts of that file you need in VB/VB.NET code. This includes Constants, TypeDef's, Structures, Enums, Funtion Headers (Declare) and any code.

Hello there!
I want to know is there any possible method to be notified when the computer (which is a member in a LAN) is disconnected?
The program is running on the computer, and I want to be notified when the computer is disconnected and connected.
Thanks

There is no event in the normal sense. You could possibly come up with a WMI event on a change to the instance of Win32_NetworkAdapter representing your NIC. You would have to subscribe to the __InstanceModificationEvent on that instance. It SHOULD be fired when there is a change to the NetworkConnectionStatus of your Win32_NetworkAdapter instance.
EventQuery Class[^]
Your WQL statement would probably look something like:
SELECT * FROM __InstanceCreationEvent WHERE TargetInstance ISA 'Win32_NetworkAdapter'

from google search: vb.net crystal report installer
http://www.vbcity.com/forums/faq.asp?fid=54&cat=Crystal%20Reports
The Solution:
Some basic info first; I was using VB.Net (Visual Studio.net 2003) in a Windows Form. The version of Crystal Reports used was that which came bundled with Visual Studio (this appears to be 9.1.5000.0 according to the reference within VB Studio). The reports used are embedded within the project. Here’s what I did. Apologies in advance if much of this is common knowledge –but it’s usually the simplest point that if overlooked causes the whole thing to go pear shaped and fail to work.
Producing the Deployment Project:
Open Solution Explorer, right click on the “Solution Name” at the top and Add a New Project. On the window that appears, move to Setup and Deployment Projects. Click on Setup Project (not the wizard), put a name for your deployment project (make a note of the location where the folder that the deployment project will be created in) and then click OK. A File System dialog will appear – solution explorer should be displayed on the left of screen. Within solution explorer – right click over your deployment project and select Add – Project Output. Another window will appear – select Primary Output (make sure configuration is showing Active) and click OK. This will result in the detected dependencies being updated & a primary output icon appearing in the deployment project. Right click on the deployment project name again and Add – Merge Modules. Add the following modules.
Crystal_Database_Access2003.msm
Crystal_Database_Access2003_enu.msm
Crystal_Managed2003.msm
Crystal_regwiz2003.msm
VC_User_CRT71_RTL_X86_---.msm
VC_User_STL71_RTL_X86_---.msm
These were the appropriate modules for my application given that I am using VS 2003. You can check your specific needs by going to this site
click here
And finding the environment appropriate to you i.e. VB.net 2003, Full versions of Crystal Reports etc…
Right click on Crystal_regwiz2003.msm and go to its properties. Enlarge the MergeModuleProperties tree and enter the product licence key. This can be found by opening the Help menu on Visual Studio and then opening About Microsoft Development Environment. You will see the 19 character licence code for Crystal Reports in the Installed Products List.
Go onto Build – Configuration Manager . Check that the Project & Deployment Project which appear are set to “Release” and the Build check box for each is checked. Build the Project. If all is well the build should show no errors.
If this has gone according to plan you should now have (in the folder specified in the “location” window given when you added your deployment project) a debug and release folder. The release folder will contain
setup (application)
setup (config file)
an installer package.
The release folder is all that is needed to deploy the application on another machine.

To deploy your application, you need to create a setup project and add the necessary merge modules to your application before you build your solution.
Open your Windows application.
In the Solution Explorer, right-click your Windows application solution, point to Add then click New Project.
In the Add New Project dialog box, select Setup and Deployment Projects in the Project Types pane and select Setup Project in the Templates pane. Click OK.
In the Solution Explorer, right-click the Setup Project, point to Add then click Project Output.
In the Add Project Output Group, select Primary output and click OK. Any dependencies, such as the Managed.msm, are added automatically.
In the Solution Explorer, right-click the Setup Project, point to Add then click Merge Module.
In the Add Modules dialog box, select the following merge modules to add to your Setup project and click Open:
Database_Access.msm
Database_Access_enu.msm
regwiz.msm
For a description of these merge modules see Crystal Reports Merge Modules (ms-help://MS.VSCC/MS.MSDNQTR.2003JAN.1033/crystlmn/html/crconcrystalreportsmergemodules.htm). Note If you deploy a Windows application that uses an ADO .NET dataset, you also need to include the VC_CRT and VC_STL merge modules.
In the Solution Explorer, right-click the regwiz.msm file and choose Properties.
In the Properties window, expand MergeModuleProperties and enter a valid license key in the License Key properties box. Note Providing the license key is a mandatory step whenever you deploy a Crystal Reports for Visual Studio .NET application. A license key will be given to you once you have registered Crystal Reports for Visual Studio .NET. You can find the license key in the About dialog box. From the Help menu, choose About Microsoft Development Environment. The keycode is listed in the Installed Products field.
From the Build menu, choose Build Solution to build your application. When deploying to a client or server computer
