Hi,
this can not be done.
new A() is an object, it could have a name.
objectA is not an object, it is a variable, it holds a reference to the
class A object. There could be many more references to the same object, it suffices
to do A* objectB=objectA;, now how would the class A object have to know
the name of all the variables pointing to it, and in particular the one you want??
Suggestion: give your objects a name by providing a Name property and/or a name argument
in their constructor, so new A("aha"); would create a new class A object and
give it the name "aha". Now you can ask that object for its name, and/or you can override
its ToString() method so it identifies itself. Remark: this works independently of the
variable(s) that may refer to that object!

Hello. I have to parse an HTML file and extract data from it. Currently I load it into Excel and then save as a .csv file. Then I load the .csv file and parse that. I now have to get the data directly from a web page into .csv format. Has anyone out there attempted something similar. Thank you.

Are you using C++ and .NET ?

I'm using VC++ 6.00 and Visual Studio 2005. I think IHTMLDocument will help me but I can't figure out how to implement it. I'm scouring the web for an example.

OK, so VC6 doesn't use .NET. VS2005 does. If you're not using .NET then you're in the wrong forum. Try the Visual C++ forum.

Hi Friends,
In socket programming I want to connect double byte charcters.
Earlier we used recv() function for single byte charcter.
If we use double byte chracter in below recv function, its coming as a question mark symbol.
If anybody knows how can I handle double byte charcter in Scoket programing(recv function),Please let me know.
My codesnippet:
while( bytesRecv == SOCKET_ERROR ) {
bytesRecv = recv( ConnectSocket, recvbuf, 64, 0 );
if ( bytesRecv == 0 || bytesRecv == WSAECONNRESET || CheckTimeOut()) {
return CloseListen();
}
}
Note:Here recvbuf works for singel byte not for doublebyte charcters.
Thanks in advance.

Looks like you're in the wrong forum. C++/CLI is C++ with .NET. You want the visual C++ forum.

Hi all,
Is there something in boost that I can use to check if a file is existing and if the file is working.
for example string file = "c://sample.doc", is there something from boost that can see if the sample.doc exists in c: directory?
Thanks,
Jj

AS you're using .NET, use File.Exists. If you're not using .NET, try using the right forum.

Hi Christian,
I am just using regular c++ at visual c++.

Did you mean to ask this in the .NET forum ?

Actually the whole thing sort of makes sense. Years back before the web was so large, forums and news groups were a logical mechanism for gaining information. Now anyone that is capable just searches and finds it, most of the time. So now in these forums we are left pretty much with the not capable category ( filet-o-fish). I bet the VB forum is very busy, and C# isn't far behind it!

The C# forum is WELL behind the VB.NET one....

I hate filet-o-fish. It is just not natural. A tasteless by product with lots of guts.

Hi, I'm using Visual Studio 2005 C++/CLI. I have a TreeView Control that displays a few nodes with some sub-nodes in each. I have written the application so if I right click on a sub-node I get a ContextMenuStrip where I can select "MenuItem". If I left click on a sub-node FIRST (thus selecting the node) then right click to select "MenuItem", I can then use...
TreeNode^ selectedNode = this->treeViewInstruments->SelectedNode;
...to get a copy of the selected node. However, if I DO NOT left click on the sub-node first and simply right click on it and then select "MenuItem" the above line of code returns an undefined value. I added code to respond to the mouse right click on a node but I can't seem to set the node as selected. I just want to be able to "set the node I just right clicked on to the selected node".
Thanks
Buck

Sorry, I didn't get you... Are you trying to select a tree item using the right click?
|

Hey Buck,
I have not got around to doing this with the .NET TreeView yet but I had to deal with it in MFC years ago so it should translate.
In my OnContextMenu handler I used the tree control HitTest() to discover the node that was clicked on. I see in the BCL TreeView documentation it has a HitTest() method. I don't know if translating the point would still apply in the .NET environment in that it might already be done.
void CEdTree::OnContextMenu(CWnd*, CPoint point)
{
CPoint pt(point);
ScreenToClient(&pt);
_nmRClickItem = tree().HitTest(pt);
|
|
|
|
|
Yes, I looked up the HitTest() doc and implemented it and it worked wonderfully.
Thanks Mike,
Buck
