Have you considered using _getche()? That way you can control exactly how many characters, and which ones, are entered.

Hi all!

I've a dialog, in the function : DoDataExchange(CDataExchange* pDX)

//{{AFX_DATA_MAP(CCEdataTextEditorDlg)<br />
	DDX_Control(pDX, IDC_BMP_NEW, test);<br />
	//}}AFX_DATA_MAP

in OnInitDialog():

DWORD dwStyle = WS_VISIBLE|SS_BITMAP|SS_NOTIFY;<br />
	cRect.SetRect( 0, 0, 17, 15 );<br />
	m_csNew.Create(NULL, dwStyle, cRect, this, IDC_BMP_NEW);// IDC_BMP_NEW is declared in a resource file (myResource.h)<br />
	m_bmp.LoadBitmap(IDR_BMP_NEW1);// In resource.h<br />
	m_csNew.SetBitmap(HBITMAP(m_bmp));

.h file :

CRect cRect;<br />
  CStatic m_csNew;<br />
  CBitmap m_bmp;<br />
  CMyClass test;// Here, i declare a class that extends CStatic<br />

anf, finally, i get a error when i compile :

Debug Assertion Failed!
...
File : wincore.cpp
Line : 312

Do u see my pb?? Help me

PS: when i delete DDX_Control(pDX, IDC_BMP_NEW, test);
--> it's OK, but i have any actions!

I think, we have to declare m_csNew.Create(...) before DoDataExchange, but i don't know how to do it Big Grin | :-D

Assertions happen at run-time not compile-time.

Have you set a breakpoint on line 312 of wincore.cpp?

From the code snippet you've provided, two CStatic variables (m_csNew and test) are being mixed. If you already have a static control as part of the dialog template (test), why are you creating another at run-time (m_csNew)?

Unless you are bent on using a static control to display the image, why not just use a picture control. It's much easier and doesn't require any code.

I think this will depend a lot of how your map is implemented. You know, if I had to respond to your question like it is asked, the response is simple: it's the straigh line !! But I suppose it's not the solution you want to hear isn't it Poke tongue | ;-P

? So try to be a little bit more precise...

You can also look for the A* pathfinding algorithm (a google search gave me these links[^]

Maybe it will be helpfull...

I have implemented this algorithm but for a specific application (a game in fact). But I was using hexagonal cells and the distance between two 'cells' was always 1 in my case.
So I think your implementation will be very different... But I can send you what I've done if you want to have an example... I don't have it here so I will send it to you when I'm back home. Just give me your e-mail adress.

Also, there are plenty of examples on the web and I think once I saw an example that was describing exactly the scheme you are asking for: the distance between two points is not equidistant (and there you'll have to play with the weight of the path between the two points).

I'm trying to programmatically adjust the playback volume of media files. Let's say u simultaneously play two .mpg files, one file plays at a very low volume, and the other plays at a very high volume.

does anyone know how the playback could be adjusted to 'equalize' the playback volume? without adjusting the device_volume, of course...

(currently using directshow, but any solution is welcome)

Hello. When i use .Net Framework 1.1 and i add any key event in text box. In program while i press ENTER, i hear a sound. Hod do i disable sound or override it?

I Use c++ and .NET Framework 1.1.4322

I have found a workaround. In keyPress event there should be e->Handled = true;, note that it can block all keys when active, so you must add at the end

if (e->KeyChar == 13)
{
e->Handled = true;
}

I also notice that this post shoud be in .NET Framework or in managec c++ catagory

Hello guys,

Requirement:My Application should work with any baudrate starting from 01- 256k ideally and i need to implement for 76800 baud with out fail.

Constraint:We are able configure the bauds from 0 - 9600 (all the numbers), 10400,14400,19200,38400,56000,57600,etc..... when i give different baudrate from the above list, the error comes is Invalid Parameter.

Question: Is there any work around to overcome this constraint.It's really urgent.

can someone through light on this.????

Thanks in advance.

You're doing something wrong. A CString can hold up to 2 billion characters.
