Hi, thanks. I think I am close to the solution.
One more thing. The article you referred to me asks me to copy my exe to the bootstrap folder location and write a .xml file in it. Please verify whether I am writing the correct code in it or not.:
<?xml version="1.0" encoding="utf-8"?>
<Product xmlns="http://schemas.microsoft.com/developer/2004/01/bootstrapper" ProductCode="PrerequisiteName">
<RelatedProducts>
<DependsOnProduct Code="Microsoft.Net.Framework.3.5" />
<DependsOnProduct Code="Microsoft.Windows.Installer.3.1" />
</RelatedProducts>
<PackageFiles>
<PackageFile Name="PrerequisiteName.exe" />
</PackageFiles>
<InstallChecks>
<ExternalCheck Property="PrerequisiteName" PackageFile="PrerequisiteName.exe" />
</InstallChecks>
</Product>
Thanks

I'm looking for a .NET (much preferably open source in C#) library for dealing with fixed length field text files. It wouldn't be too much to write one, but existing, tested work is always nicer, to start with.
I will be extracting data in fixed length fields from files produced by a PBX. Each PBX has its own file format, as well a set of record formats. I'm looking for a library with a nice a simple way of using dynamic file and record formats, e.g. read from an INI or XML file.

Hi Brady,
I was told Google insists XHTML to be correct before it is willing to index.
yours isn't, see here[^].
So IMO it isn't about meta tags. yet.

Ah, thanks. I'll fix all those train smash errors and hopefully placate the Might One. I just wonder why they couldn't tell me in my Webmaster Tools data.

Hi Brady,
There is a library here on CP that does fixed length or delimited files.
Search the articles for FileHelpers. I would give you a link but I'm stuck on 53.6 Kbs for the moment and everything takes so much time that I can't be arsed!

Hi,
I have a .net solution that contains Windows Service Application. This application has app.config file that stores the connection strings and Appsettings. To encrypt these sensitive information, i am using the protectsection and unprotectsection with 'RsaProtectedConfigurationProvider'. These methods are written in a class "UsingRsaProtectedConfigurationProvider", in the WindowService project.
I have created a console application in the same solution. These console application calls the protectsection() method of class "UsingRsaProtectedConfigurationProvider" while encrypting. These console application is executed first to encrypt the app.config values.
However, when i start the windows service, it gives me an error "Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened."
I am pasting the inner exeception here. Please help me as i am unable to proceed.

Hi All,
I am new to this forum. We did one project in vb.net. I do not know how to prevent from decompilation? One way is there to prevent, is using third party softwares but i do not want to use those softwares. Is there any way to prevent through assemply level coding and from any way means without using third party softwares? Please give me some solution to prevent my code from decomipilation.
Thanks in Advance,
Savitri

Simply put, you can't. Even an obfuscator won't prevent it, only make the code more difficult to read.

If you are having Visual Studio its having a obfuscation tool thats Dotfuscator.By using that you can obfuscate your code.It doesn't means that your code is 100% safe but dotfuscator will make your code difficult to understand after decompilation.So you can try that.

By design .NET embeds rich Meta data inside the executable code using MSIL. Anyone can easily decompile your DLL back using tools like ILDASM (owned by Microsoft) or Reflector for.NET which is a third party. Secondly there are many third party tools which make this decompiling process a click away. So any one can easily look in to your assemblies and reverse engineer them back in to actual source code and understand some real good logic which can make it easy to crack your application.
The process by which you can stop this reverse engineering is using “obfuscation”. It’s a technique which will foil the de compilers. There are many third parties (XenoCode, Demeanor for .NET) which provide .NET obfuscation solution. Microsoft includes one that is Dotfuscator Community Edition with Visual Studio.NET

Hi,
I am working on shared add-in in c# for Excel. Let us consider 3 components A,B,C. Where A is a Shim,B is Shared an add-in(used IDTExtensibility interface) which creates all tool bars, menu items for Excel and C is an automation add-in which contains UDFs.
I have static property in Automaion add-in(C) which set/gets Excel Application object. Whenever OnConnection(..) of shared add-in is called from the framework, I am setting the Excel application object using this property. So When I type some UDF in Excel, it uses this Excel application object for further work on Excel.
Recently I tried to remove the Shim and put the VSTO on it. When I use VSTo, it doesn't use shared add-in.Here also I set the Excel application object by using static property. Now I have I enabled this Auotomation add-in(add-in->Options->Automation Tab).But when I type some UDF in Excel cell, excel object is not available that is set from VSTO.How do I pass reference to Excel object to Automation add-in so that the same Excel Object is available in Automation add-in when we type some UDFs.
What I observed here is VSTO and Automation add-ins are working in different AppDomains.
Please help me.
Thanks.

I am sending objects across the wire, and receive some back.
I can identify if an object was sent and returned, or if it is a new object.
For returned objects, I would like to substitute the original object into the deserialization process in the OnDeserialized method of my framework's base class.
This allows all references to the object that got sent to remain intact, without having to get a new deserialized object and then copy all it's fields onto the old object.
----------------------
Functionally, I add a class above the current base class, with two fields:
Int64 ObjectSerialNumber; always unique.
bool ObjectIsNew; which is set to true on creation, and false when it finishs deserializing (see below).
When objects are serialized, they are stuck in a dictionary hooked to that comms session, hashed by ObjectSerialNumber.
In the base OnDeserialized, I have already deserialized ObjectSerialNumber, and ObjectIsNew, but none of the other fields.
If ObjectIsNew != true, I get the original object from the dictionary and insert it in place of the object that the stream is being deserialized into.
If ObjectIsNew == true, I set ObjectIsNew = false and continue using the one provided by the deserializer.
------------------------
The only fly in the ointment is that "insert it in place of the object" really means:
this = originalObject;
I have not found a way to do this in .NET. Anyone have an idea of how to go about that?
Is there a way into the fields that are hidden in 'this'?
The whole framework is already 'unsafe'.
Thanks

I ran FxCop over my assembly and got the warning about not indirectly exposing methods with LinkDemands (CA2122 help link). The original code was like this (Marshal.GetLastWin32Error is the method with the LinkDemand):
Dim extendedStyle As Integer = NativeMethods.GetWindowLong(hwnd, GWL_EXSTYLE)
If extendedStyle = 0 Then
Throw New System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error())
End If
I then moved the exception throwing into a method on the NativeMethods class and the code now looks like this:
Dim extendedStyle As Integer = NativeMethods.GetWindowLong(hwnd, GWL_EXSTYLE)
If extendedStyle = 0 Then
NativeMethods.ThrowWin32Error()
End If
<SecurityPermission(SecurityAction.Demand, UnmanagedCode:=True)> _
Friend Module NativeMethods
Friend Sub ThrowWin32Error()
Throw New System.ComponentModel.Win32Exception(Marshal.GetLastWin32Error())
End Sub
End Module
As expected, the original method is no longer flagged by FxCop. I expected the new NativeMethods.ThrowWin32Error to be flagged, but it is not. Neither the NativeMethods class nor the method have any attributes. Does anyone know more about LinkDemands or this warning that could provide an explanation for why this is not flagged? (EDIT: I am getting the FxCop warning now without the attribute.) Is applying a SecurityPermission attribute the right way to deal with that warning?
I am getting the same message for the serialization constructors of Exceptions that call GetObjectData, and I assume that whatever I end up doing for this situation will need to be done for them too.

Hi Guys,
I have a service running under a restricted access user (say - AppUser) that is not related to the user who is currently logged in to windows (say - JSmith).
I'm trying to get the user name of the currently logged in user (JSmith) from an application running under AppUser.
How would i go about doing this?
Regards
Tris

Hello,
I'm trying to change background color of some line in a .cs file.
MSDN seems pretty straightforward regarding custom colorization: one has to define custom colorizer, and probably some font items. But the idea behind it is adding new language highlighting rather than modification of predefined one.
------
It could be a wrong forum, however answer is:
IVsTextLineMarker should be used in this case. For more details see: MSDN forums[^]
Best Regards,
Sergiy

Why, that's phrased like a contest
You could use the DeflateStream[^] that comes with the Framework, or the GZipStream[^].
If you can use third-party libraries then you have, again, two choices;
* DotNetZip[^]
using (ZipFile zip = ZipFile.Read(sourcePath)
{
zip["myFile.dll"].Extract();
} Or;
* #ZipLib[^]
using ICSharpCode.SharpZipLib.Zip;
FastZip fz = new FastZip();
fz.ExtractZip("myFile.dll", "C:\TEMP", "");

hi forum,
My question is that is there any method to control the webcam settings such as contrast, brightness, etc. in vb.net?

The simple answer is NO.
VB.Net does not has any supporting API/class for webcamera. But you can try to look at the internet, there are quite a number of open source libraries which do this.
Good Luck.
