Oops, I forgot to check the "Do not treat < as tags" checkbox. The post should look like

"Use the array template (or generic, I don't know) class."

array<byte> ^buffer = gcnew array<byte>[10];

By using this following error...
<code>
array<byte> ^buffer = gcnew array<byte>[1024];
</code>

Error 1 error C2065: 'byte' : undeclared identifier
Error 2 error C2728: 'cli::array' : a native array cannot contain this managed type
Error 3 error C2512: 'cli::array<Type,dimension>::array' : no appropriate default constructor available

Yeah, you need to replace the [] with ().

Databinding inside User Controls.

Gustyn27-Dec-05 10:06

27-Dec-05 10:06

OK, I have been developing an interface for editing records in our database.
I want to set it up as a control that I can use in other applications I
build. I am using databinding to tie the fields to my controls, such as
labels and textboxes.

I can create a solution for a stand alone application that runs like I want,
but whenever I create a solution for a control, then none of my data shows
up. I have tried making C++ controls (the language I am familiar with) and
VB and even C#. I get the same result: The interface compiles and displays
as designed, but no data.

When I add the control to the toolbox, I get the control plus a dataset and
adapter, but no databinding control.

Can anyone point me to any articles regarding creating user controls in managed C++? I am interested in reading about how to "subclass" the controls in C++ .NET so they have custom appearance/behavior. I've tried googling but either there is very little out there or I am googling the wrong keywords.

Thanks

Why is common sense not common?

Never argue with an idiot. They will drag you down to their level where they are an expert.

You probably want to post in the VC++ forum instead of this one. This one's specific to managed code. Even there, you might not get an answer, but I wish you the best of luck Smile | :)

look for the CFRONT compiler. It is the "original" C++ compiler which first converted C++ to C. Google for CFRONT

Hi, In the description of SetWindowText(), it states that "it cannot change the text of a control in another application." Anyone know what will do this, given the handle of the window has been enumerated ?

String spliting

Suppose I have a:

char txt[80];

which holds '1','2','3',' ','4','5','6',' ','7','8';

now I declare 3 ints:

int 1st, 2nd, 3rd;

I want to put into them as follows: 1st==123, 2nd==456, 3rd==78, but the length of each number can be different, eg. txt may also hold: '1',' ','3',' ','5','5','5'

Could you please help me?
thank you in advance Smile | :)

This is an old-fashioned solution, but try this:

char txt[80];
int first,second,third;
sscanf(txt,"%d %d %d",&first,&second,&third);

Did you intend this:-
when the user types something, the characters shouldn't appear?

If yes, then ES_PASSWORD style with the edit control is what you are after.

Thanks one more time, maybe i m wrong but i create my opengl window with glutCreateWindow and everything was created with glut expresions, it creates an int type window and i can't convert it to HWND, is there any other way to make it topmost or to make an notopmost my vb.net window?...

Hello.
I thing the HWND is a LONG INT, but hwnd is used in c++ not in VB. "this" is a pointer used in C++ and in C#.

The code I gave you was MFC, and you need to convert that to the VB.NET equivalent. I don't know VB.NET so you'll have to ask a VB.NET guy to convert it for you.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
