0I Have a vb6 application that uses .net objects via COM. When one of this objects calls code which instantiates XmlSerializer vb6 aplication crashes.Just this line fails: Dim x as new XmlSerializer(GetType(CustomClass))I agregate that these objects load assemblies dinamically but only it crashes over vb6 aplication. In .net 100% aplication this not happens.
View 2 RepliesI'm trying to concatenate an object that instantiates the client class (for example) with their respective property that ONLY through a variable, like this:Dim fieldx As String fieldx = "Name" Dim customer As New Customer customer.fieldx = "Joseph" customer.Name = "Joseph"
Actually I use array, but to simplify my question, I used a variable as an example.The error is that the compiler tries to find a property with the name fieldx in my class. How to tell the compiler to retrieve the value contained in the variable instead the name of it?
I have not yet tested this..but before I do that, I am just wondering, let's say you have a byte stream, and you want to deserialize that into an object?[code]...
View 3 RepliesI am using the XMLSerializer to create an XML Schema. In one part of the XML, I have an element called 'parameters', which returns a collection of strings. The output is supposed to look like this:

I'm trying to serialize a user's preferences by means of an XMLSerializer. The preferences class contains Strings, Integers, Booleans and several Color structure variables. The serialization doesn't throw any errors, however the generated xml file has empty values only for the color variables.I tried the following two declarations of the XMLSerializer object, neither workerd.

Why won't XMLSerializer process my generic list?
Sub Main()
Serializing()
End Sub

I get an exception on the "Dim ser" line, saying "Testing.Module1 is inaccessible due to its protection level. Only public types can be processed." ("Testing is the name of the application, and "Module1" is the name of the module; this is a console application).
I have a custom class that has one property as a collection.For some reason XmlSerializer doesnt like the class having a collection property and the Serialize Fails!If I remove the collection property it works! Is there a special way of getting the collection in the class to work?
View 1 RepliesI've been having problems with following code on some computers, while it's worked super on others (most):
Dim xmlSer As New System.Xml.Serialization.XmlSerializer(GetType(XMLContext))
which produces the stacktrace:
System.ArgumentNullException: Value cannot be null.
Parameter name: type
at System.Xml.Serialization.XmlSerializer..ctor(Type type, String defaultNamespace)
How can that code throw that exception, when the argument is drawn from a gettype call, and note that it doesn't happen when debugging on my own PC, only when it's installed on some of the client PC's???
I am trying to deserialize an Xml file content into a specific object. Everything runs fine but when I include empty tag of type date or time in my xml(having xsd that describes my xml structure) the deserialization fails. What can I do to make deserialization working when empty date tags are appear?
View 1 RepliesIs there any way to create an XmlSerializer that stores along with the serialized data the data type, then when deserializing, it automatically identifies the type of the serialized object and creates an object of that type (returned as object).
View 1 RepliesI have the following class which I want to serialize to XML:
[Code]...
I wish to put the XMLSerializer behind a 'facade' class of mine so that user wont have to supply type info to the constructor. But doing this has a problem. Consider this class:
Class XmlFormatter
Private Shared xs As XmlSerializer
Public Function Deserialize(ByVal serializationStream As Stream) As Object
Dim o As Object = Nothing
[code]....
The problem is that the user of this class cannot use Deserialize without first using Serialize because the XMLSerializer instance is created in Serialize and it is shared. But using Deserialize without this instance will simply return Nothing.
I've had an app running without problem for a few months now. When the app crashed it would pop up a message where I could look at the error message to determine why it crashed. After a recent Windows 2003 update, when the app crashes it no longer pops up the message, writes to any log or appears in the event viewer so I have no idea now why it's crashing. Is there a way to determine what is going on that would help me see why my app is crashing?

I am using VB.NET Framework 3.5 . I have a very complicated program with over 40 forms and 100s of lines of coding. Earlier today, this program worked perfectly. I decided to change the Assembly Name from APA to Salamander. I do not get any errors and things seem to be going fine. Upon the next debug, the splash screen loads fine. (I am using a timer to proceed to the main form, not the inbuilt splash screen setting as I found it to be more reliable). However, when the main form loads, none of the pictures (resources) load and it exits itself immediately yet no errors appear at all. I think it might be to do with the .resources file but I really don't know. As I only started Visual Basic less than two months ago I'm not sure what all the files other than .vb files actually are.I really don't want to have to completely rebuild the program as my release date is in five days and as I am still at school I don't have time to complete it on top of homework. I have tried changing the assembly name back to APA again but it still does not work. I am completely stumped.
View 2 RepliesI have an application which won't run on a German version of XP. It crashes when trying to load a setting from a .exe.config file. The line it fails on is: [Code] however the value in the variable ends up as 8.0 (it is a single). In an English version of XP the value in the variable ends up as .8 as one would expect. Weird huh? Anybody got an explanation?
View 5 RepliesI am writing a system that utilizes the Timer to execute a command after an interval of three seconds. The command is to send a trigger to my RFID reader and hence the program will then decode the received data and changed it to information. It runs fine for the first few hours, but it will crash after that and the error given is an "System.NullReferenceExeption - Object reference not set to an instance of an object." error. Initially, i thought that it might be something that relates to my comobobox selected index change event that might be causing the crashes, but yet the application is crashes after i removed the section.
I fail to find the reason of the crash, even after spend fewing days finding the memory leak or some other events that might cause the crash.
I have insert TRY CATCH METHOD, just to catch the exeption error message that might cause by one of the codes, but still it doesnt show me.
I recently finished an application which I spent a long time making, but when I sent it to my friends so they could beta test, everyone single one of them said it stopped responding on start up. I took the .exe out of the project>bin>debug>application.exe and thats what I gave them, and it doesn't crash for me, so i was wondering what might be causing it to crash, or if they would need extra files for it to work properly?
Also, when my friend opened it, he says he got an error that says:
Name: Microsoft .NET Error
I have created a program in Visual Basic 2008 Express Edition, and it runs fine on my computer, but on client computers (which do have the .NET |Framework installed), it crashes.

VS2010 VB.Net
When I try to access the Macro IDE or open MyMacros I get the error: Vsaenv: Cannot find one or more components. reinstall the application. I have reinstalled (rebuild in place) VS2010 Pro - didn't help.
After the error the IDE goes away for a while and sometimes crashes and sometimes it returns to the code IDE. If I try again as often as not VS crashes hard. On reload it looks like it is going through rebuilding settings.
I have VS 2011, and I put around 10 settings that contain around 1500 lines of code in each setting + 10 images in my resources.[code]...

Yet I have having a troubling error that I can't resolve.

I am trying to make my application run on Windows 7 X64. The application runs fine, however the explorer process keeps crashing after i started or ended the application. Explorer crashes mostly on right mouse button clicks. This gives me a feeling there are pointer problems / mem overloads with the application Application CPU is set to X86, i ran into debug mode with stack traces no serious issues found. I am using a couple of Api's and i know there are rules regarding WOW64 mode however they are really unclear. MSDN doesn't supply the information i need. The information supplied only raishes more questions lol.
