How can I use a CIntArray in a struct, I'm using the struct in a CArray... heres the problem .. I have a lot of items... and then it has a sub item comprising of an unknown amount of integers (thats why I don't want to us a C array, adn i can't use int)

I can't find any references in either the October 2001 or the January 2004 MSDN's to CIntArray, so I created one. I tried this:

#include "afxtempl.h"
<br>
typedef CArray<int,int&> CIntArray;
<br>
struct StructType {
    CIntArray IntArray;
};
<br>
CArray<StructType,StructType&> Array;
<br>
...
<br>
Array.SetSize(5);
Array[3].IntArray.SetSize(4);
Array[3].IntArray[2] = 10;

and it compiles and runs just fine. What's the problem you're having?

inVariable=_ttoi(CStringVariable)

or

even better

sscanf(CStringVariable, "%d", intVarible

Hi Mike,

I presume, the code snippet below can convert a string to long, and is the most fastest method.

ConvertStringToLong( char* szFieldValue,long &lValue )
{
//Validate the string Smile | :)

int nLength = sizeof(unsigned long);
char szBuffer1[ 8 ];
char szBuffer[ 8 ];
szBuffer1[nLength] = '\0';
memset( szBuffer1,0,nLength );
szBuffer[nLength] = '\0';
memset( szBuffer,0,nLength );
memcpy((void*) (szBuffer1 + nLength - stringLength ),szFieldValue,stringLength );

for( int i=0;i

Um, there must be a ton of stuff missing from this routine because it won't compile and I can see a few ways I can get it to crash.

I know Tim, You can crash it very easily, B'coz I haven't freed the memory, and there are a couple of other mistakes as well. But my intention was only to, break the conventional approach on converting a string to int. Its just stupid to think that, someone else will do all the jobs for U. You may have to correct the mistakes, if thr are any.

Window Background color

How do I change the window background color in the OnPaint message from white to a different color ?

Re: Window Background color

Michael Dunn9-Jan-04 17:09

Michael Dunn

9-Jan-04 17:09

OnPaint() is where you draw the contents of the window, so you just create a brush of the color you want and fill the client area with that brush.
Alternatively, if you will always use the same color, create the brush first and set your window class up to use that brush for the background.

OK,
another question:

if Im not creating a window class (using NULL) can I just somehow change the default brush for it ?

The Bestway to paint the background of ur window is in the WM_ERASEBKGND message.

Steps:
First map the WM_ERASEBKGND and then write the OnEraseBkgnd as follows.

<br />
BOOL CDesktopDlg::OnEraseBkgnd(CDC* pDC) <br />
{<br />
    // Getting the rect ( length and width )<br />
    // of the window.<br />
    CRect rect;<br />
    GetClientRect ( &rect );<br />
<br />
    // Creating the brush to fill the background<br />
    // of our window<br />
    CBrush brush;<br />
    brush.CreateSolidBrush ( RGB (255,0,0) );<br />
<br />
<br />
    // Filling the background of our window<br />
    pDC->FillRect ( &rect, &brush );<br />
<br />
    return TRUE;<br />
}<br />

adding a C file to a CPP proj

ABean9-Jan-04 8:14

I added a C file to a CPP proj and got an error complaing about the precompiled header thing. MSDN says I should create a subproject and stick the file in that. However, I would rather not create a new sub project for a number of reasons.

As a solution, I found that I could rename the .c to .cpp and get it to compile file. Everything works but I'm wondering if there is a ticking time bomb just waiting to happen after this program goes into production.

Thanks,
Al

Is it possible to do that for a single file in VC7? MSDN seems to indicate that the only way to do this would be to stick it in its own sub-project.

In any case I would rather not change ANY environment settings because this is for inclusion into an open source project that can be compiled on many platforms/compilers. Renaming it to CPP seems to be the easy way out. It’s just a collection of functions so I really can’t see how it would hurt. But thought it would be good to check with you guys first.

Disable Mouse clicks inside rich edit control

Anonymous9-Jan-04 7:44

Hi, I was curious if it was possible to disable clicks within a rich edit control without disabling the entire control. My problem is even though the user cannot type inside the control, he or she can still click inside of it. Once they do this, any new text written to the control by my app is printed in the new position clicked earlier by the user. Must I line scroll before each attempt to write to the control to prevent this problem. Or is there an easier way. Thanks.

Don't assume anything about the control or the cursor position within. When the control needs to be updated, set the cursor position accordingly, don't assume it's already correctly set.

A rich person is not the one who has the most, but the one that needs the least.

You can subclass the control and handle click messages like WM_LBUTTONDOWN, WM_LBUTTONDBLCLK, and so on. The message handlers should be empty so that nothing happens in response to those messages.
