I have the following class:
#pragma
onceusing
namespace System;namespace
AutoTickets{
ref
class Model : System::Object{
public
:Model(
void) : M_model(""){}
Model(String^ model) : M_model(model)
{}
property String^ model{
String^ get() {
return M_model; } void set(String^ p_model) { M_model = p_model; }}
virtual String^ ToString() override
{
return M_model;}
private
:String^ M_model;
};
}
For some reason ToString() is not being overriden.
I have other classes that do the same thing and work fine. When I call ToString on an object of this type all I get is "AutoTickets.Model".
I'm not sure if I'm doing something wrong here. I'm relatively new to .NET.
I'd appreciate any help with this. I made the class explicitely inherit from System::Object just to make sure. Either way Model::ToString() is not being called. I put a debug MessageBox::Show() to see if it was being called and it isn't.
Can't override ToString().

Weird thing is that I have three other classes that override ToString() and they work well. I can't seem to figure out what I'm doing wrong here. I've been looking at it for about two hours now. Also that's all there is to the class.
Thanks either way.

I can't think of anything other than a tip to narrow it down. On each project, go to the C/C++ settings, Command line, and under "Additional options" add "/Bd." This will output all the compiler settings, including assembly references that the projects make.

Looks like you're doing fine so far! Just a weird bump in the road, that's all. If it ends up being a bug in VC++, then you get the chance to tell Microsoft off and report a bug at the product feedback site. :)

I am not able to reproduce your problem. I tested this with:
int
main(array<System::String ^> ^args){
AutoTickets::Model^ mymodel = gcnew AutoTickets::Model( L"test" );
System::Object^ obj = mymodel;
Console::WriteLine(obj->ToString());
return 0;
}
obj->ToString() calls into Model::ToString() as expected.
Which version of Visual Studio are you using

It appears it was a problem with VC++. I excluded the file from the project and readded it and even though I had (unsuccessfully apparently) to save the file it did not save the file. So the version of the file without the ToString() override function wasn't being compiled.
Either way I though the compiler would compile the file currently being edited even if it wasn't saved.
There was another rather nasty bug that I had a couple of days ago. I posted here. Also someone appeared to have the same problem before. It happens when you create a project and move the project file to another computer.
For some reason the compiler looks for a file named (IIRC) comlib.hlp.
Apparently it had something to do with pre-compiled headers. Since I don't need pre-compiled headers I disabled them from the project properties and the problem was gone.
Well thanks for the time on trying to help.
bye now :)

Try taking the steps I've taken to see if you can pin down one end of the working v. not-working spectrum. Create a new CLR Console project, copy/paste the code you posted here, and then replace main() with the version I provided and test it.
If this works, then you have a project to compare differences against.

So I did that and it worked fine.
Do you have any idea of what would cause something like this in the project configuration I can't think of anything that would cause something like this.
Once again, I'm relatively new to .NET and programming under windows.
Thanks
