Use the \\server\share convention, also known as UNC.

Any function or method that can handle UNC will work.

Use the WNetOpenEnum() and WNetEnumResource() pair.

Use CopyFile() or SHFileOperation().

Have you read the documentation and the examples for the functions I mentioned?

Well, this is probably one of the biggest newbie question around here, but I'm having problems with assigning my Label text to a variable (ex a string).
My problem explained with code looks like this:

Label *myLbl;
string myString = "Hello there";

myLbl = new Label;
myLbl->Text = myString; //error C2664 Cannot convert from string to System::String __gc *

This does obviously not work, and I have searched for quite some time now after just a simple sollution to this simple problem, no result finding something. So I hoped someone here could help me out with this one.

Best Regards,
Hmmkk

The Managed C++ forum might offer better help.

Just my guess, maybe you need to use the c_str() method?

myLbl->Text = new System::String(myString.c_str());

Well yes, I was afraid that this belonged there but I was not totally sure.
Thanks though.
But well it didnt quite solve my problem, now I get the error;
Just-In-Time Debugging
System.NullReferenceException

To make the code a little more clear, if now it matter I don't know.

This is how I want it.

lblQ->Text = myQuestions[CurrentQuestion]->getQuestion()

myQuestion is a pointer class and getQuestion returns the variable theQuestion which is defined as a string.

and also I just tried two ways:
1:
lblQ->Text = new System::String(myQuestions[CurrentQuestion]->getQuestion();.c_str());

2:
myQuestions[CurrentQuestion]->setQuestion("hi");
string temp = myQuestions[CurrentQuestion]->getQuestion();
lblQ->Text = new System::String(temp.c_str());

Both gave the Just-In-Time debugger error.

Spying / Docking

Howdy-

I am looking for some clues.

I need to make a window that will track another application, and "dock" itself to the side of that other application.

I am looking for the and easy and efficient way to watch the position of another window and buddy my window up to it. All clues welcome!

Thanks

I am writing a add-in for some other program (can't say which) -- and though this program offers a plug-in interface, they offer no UI support.

For the sake of a demo, we want to put a button on their window. I plan to do this by tracking their app (size, location, focus) and positioning myself next to them... like a little puppy dog chasing his master -- my button/window will track this other application.

My assumption is that I mush hook their application with something like SetWindowsHooEx() and get the important messages and post them back to my app which will reposition itself to match that app.

I guess the question is -- is there any other way to do this, than to create a DLL, inject it into their process space, and post messages back and forth?

Thanks

Nope, Unless that APPLICATION expose Interface to do so!

bit field question

lynchspawn2-Jun-05 7:39

I don't use bit fields much at all. I have a simple struct as folows (on an INTEL format machine):

typedef struct{
short f1 : 13;
short f2 : 1;
short f3 : 1;
short f4 : 1;
} tststruct;

tststruct tst;
tst.f1 = 8000;

what ends up happening is f1 gets a value of 0xFF40 instead of what I thought I would get (0x1F40). The other members (f2,f3,f4) are all 0x00 as I would expect.

Any idea why?

Maybe the compiler fills up the remaining 3 bits with ones instead of zeros? Maybe you can do an & with 0x1FFF to filter out the first 3 bits.

Thanks.

Here's what I found: if I use unsigned shorts, everything works fine. Apparently, the value is sign- extended when using signed variables - so the 1F40 (when looking at it as a 13 bit number) is a negative number and the sign bit is extended out when placing the value in the struct (giving FF40). Hope that makes sense.

Thanks - I got there eventually but it really looked strange at first.

I have a project where a class is being registered. The class contains some code that finishes with AfxRegisterClass(). Why register a class?

This[^] missive seems to support the absence of a native beast. (But seriously, it's quite easy to wrap a Tcl with C/C++ - I assume that's what WinCVS does).

Yes but I'm trying to make something nice and portable - I need Cygwin, Perl, Python and Tcl/Tk on my work PC because of this kind of thing !
They have to be the right versions for some tasks too.

No, they it does need Tcl/Tk. It uses Perl/Tcl/whatever for macros. But for vanilla CVS operations, as you can execute using the command line tools, and then some, there is no need for any scripting language. I've been using WinCVS like this for the last 4 years. Smile | :)
