Hi,
I have the following code in the module of my DLL
Private m_objAppConfig As clsAppConfig = Nothing
Public Property objAppConfig() As clsAppConfig
Get
If m_objAppConfig Is Nothing Then
If False Then 'Something related to the load of the program in VB.Net
Return Nothing
Else
Throw New ExceptionImproperMethodCall("The configuration was not previously loaded")
End If
End If
Return m_objAppConfig
End Get
Set(ByVal value As clsAppConfig)
m_objAppConfig = value
End Set
End Property
It works OK while running, but when I open the project in VB.Net it throws the ExceptionImproperMethodCall several times.
Have you ever seen this?
Thanks

Hi,
the exception you get is right there, it gets thrown by the get part of the property (Throw New ExceptionImproperMethodCall("The configuration was not previously loaded")) as long as no value has been set. So some code must be using the getter, maybe a constructor somewhere.

It seems I'm not clear.
I've put the exception to avoid any use of the programs using the library in a way that I don't want. The library is used for at least one colleague and, of course, several users.
And it works. The compiled programs run perfectly.
Is when I load the source with the VS 2008 that I get the messages. Before actually running the application.
Thanks again

Visual Studio does execute parts of an app while developing, i.e. without actually running the app. That is how the Designer is capable of showing User Controls for instance. I'm not sure which parts execute, at least they would include all parameterless constructors for GUI Controls and Components. So check those for reading the throwing getter.
If you can locate the getter being called but find it hard to prevent it, there is a DesignMode property that will help you.

Thanks, Luc
That's what I suspected.
I still couldn't find the places where is called, provided that the F5 (start debugging) goes thru the calls in the right moments, where the object has already been instantiated. The only moment where I get the exception is when I open the project. Therefore, even testing is slow, because any idea to test implies closing and opening the project.
The DesignMode works for components, that inherit from Control, do not apply for these objects, that are not controls.

Guillermo

Hi,
I am preparing a setup for a project say A and in order to run that A properly another installer say B has to be installed on target machine.
How can I prepare a setup project for A to check whether B has been installed prior or not, and if not quit the installation and install B first.

What application are you using to create the setup-package? Most of them allow the inclusion of custom setups or msi-packages that can get installed along the application.
Alternatively, you could check the registry whether B is installed under the key
SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall
If it's not, launch setup B, wait until it completes, and relaunch the A-setup. You'd need the ability to launch a custom application from your setup for this.

Currently I am using Visual Studio 2008 deployment setup for making an installer file. Please recommend me some good msi maker if you have one.
I am using following RegKey:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\MY_Prerequisite_application
Can you please tell me how to "If it's not, launch setup B, wait until it completes, and relaunch the A-setup. You'd need the ability to launch a custom application from your setup for this."

I haven't used those tools for a while. You might want to check out this site[^], has a lot of neatly categorized answers

The Visual Studio template doesn't have an easy option to launch one of the deployed files before the setup starts. Anyway, there seems to be a better solution;
Setup B would become a Merge Module[^], so that you can add it to your own setup. Once you got a Merge Module, add it to the setup.
Hello World

|

Still the problem remains same.
I have created a merge module in my solution, added the prerequisite B.exe to it and then added the .msm file to my setup project.
|
|
|
|
|
Like I already said, I haven't done this in a while and you'd have to put some extra research in it.
Anyway, there's an article on CodeProject[^] that explains how this can be done.

Thanks for the reply.
This article only explains how to add the prerequisites which are listed over there.
Is there any means by which by which I can add my prerequisite application to that list?

Yes, by putting your Merge Module in this directory;
"C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages"

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
|

The best verification is a test. I'm not the author of the article, and I haven't created any setups recently.

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.
