You have to write the implementation also in your header (*.h) file.

Printing from a CWebBrowser2 control

I wish to print the contents of a CWebBrowser2 control. I use m_htmlview.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, NULL, NULL); This prints the contents on the default printer.

However I wish to print the contents on a printer other than the default printer. Anyone got any idea how I can do this please? I have changed the default printer to the one I wish to print from, printed to it, and changed the default printer back. I don't think this is a very good way of doing it, so does anyone have any better ideas please? Confused | :confused:

Thanks

afxdhtml.h not found

Hi
I want to compile a foreign open source application written in VC++7. But I only have VC++6 (with the latest PlatformSDK). The result is, that the compiler gives me errors like "afxdhtml.h not found" etc. I suppose these headers are new with MFC7.

Where can I get the latest headers from? The PlatformSDK does not seem to have them. Or do I need to purchase VC++7?

thanks in advance

Do you really need what afxdhtml.h provides ?

Try afxhtml.h instead.

And if it doesn't compile, that's because this code is using the CHtmlEditView, which requires MFC7, thus VC7.

Gridlines without checkboxes in Listcontrol

I am using the folowing code to add gridlines to a report-Style Listcontrol:

dwExStyle = m_listSpeeds.GetExStyle();<br />
	dwExStyle |= LVS_EX_FULLROWSELECT | LVS_EX_GRIDLINES;<br />
	m_listSpeeds.SetExtendedStyle(dwExStyle);

For some reason this is adding checkboxes to my control as well as gridlines. Why is this happening Cry | :((

and how I can disable this behaviour?

Try changing the first line from

<br />
dwExStyle = m_listSpeeds.GetExtendedStyle();<br />

Distributing MFC programs

I developed a dialog based application in MFC. I don't want to distribute MFC dlls with it and so i am linking it statically with MFC.

But when i run my Release exe on Win98 machine with no VC++ installed, i obtained error that msvcp60.dll not found.

Is there any way that there'd be no need to distribute any additional dll with our applications built using VC++/MFC

msvcrt is the C runtime dll, I don't know what msvcp60 is, you should look it up in MSDN, that will tell you why you have the dependancy and you can then check out if it's something you can change.

You're right. A Google search left me thinking it is also related to the C run time. Two questions

1. Are you using any C runtime functions ?

2. Why is it such a big deal to need this dll ?

msvcp60.dll has nothing to do with the MFC.

msvcp60.dll is the MS C++ run-time. (for instance, when you use #include <iostream> and stuff like that).

Just xcopy this file.

Good for you! I *hate* apps that have to install a bunch of DLLs, because they usually do it incorrectly.

You need to do a couple things:
1. Make sure MFC is linked statically (it looks like you are doing this)
2. Are you running VC 6.0? If so:
- Go to "Project Settings" for your project(s)
- Go to the C++ tab, and change the combo box to "Code Generation".
- There is a box that says, "Use Runtime Library". It should *NOT* be an option that has "DLL" in the name. Change it to the corresponding option that does not have DLL in its name.
- Make sure you do step 2 for Debug and Release (and any other project configurations you have.)

If you are running VS.NET, the option is still there, but getting to it may be a little different.

Hope this helps.

hi, I want use wParam and lParam to transfer values to messege pump for futher process, just tell me how to use them.
For example,
I want sent one pointer and three integers though message to message pump, how to do this??

Thank u.

Extreme programming. Do the No.1

Re: wParam/lParam

Christian Graus30-Oct-02 1:16

Christian Graus

30-Oct-02 1:16

You're using your own message ? I would think the easiest way would be a struct, create it using new, pass the address as a wparam or lparam, delete it when you recieve it. Not all that safe, I would think, but you can't fit a pointer and three ints into one message otherwise. Why do you need to send them in the message - is it between processes ? If so, WM_COPYDATA might be the way to go.

OnMenuChar

What about OnMenuChar() processing?

I try to process a WM_MENUCHAR message in MFC: I return a MAKELRESULT(ID_SOMEMENUITEMID, 2) to say to Windows that this item is to be selected, but it doesn' t work.
The only thing that work is return a MAKELRESULT(..., 1) that says WIndows to close the menu..

Some hints?

Thanks

a problem in memory allocation

Hi everybody,

I have a strange problem with an allocation of memory for pointers of pointers.

i have done this function to allocate memory for 2 pointers of pointers:

void LoadHistoDB::AllocComptStartEndMin(long RowSize,long ColSize)
{
long i;

pComptStartMineure=new double* [RowSize];
pComptEndMineure=new double* [RowSize];

for(i=0;i<rowsize;i++)
{
="" pcomptstartmineure[i]="new" double[colsize];
="" pcomptendmineure[i]="new" }
}

so,="" after="" the="" allocation="" is="" done,="" i="" want="" to="" put="" value="" in="" them,="" ik="" that:

pcomptstartmineure[i][j]="i
pComptEndMineure[i][k]=i

i" don't="" post="" all="" my="" code="" because="" it="" will="" be="" too="" long.

so="" when="" test="" application="" with="" debug="" method="" (calling="" f5!)

when="">120 i could see in the debug window this message in front of pComptStartMineure:

CXX0030:expression cannot be evaluated

and i could see this same message for pComptEndMineure when i>202.

So where is the problem?

Thanks in advance for your help

When i>120 i could see in the debug window this message in front of pComptStartMineure:<br />
<br />
CXX0030:expression cannot be evaluated<br />
<code><br />
<br />
that means that your pointer is pointing to NULL, hence it can not evaluated the value. Normally, an attempt to access NULL pointer will give you "Access Violation" error.<br />
<br />
This dynamic memory allocation is not easy to deal with. Ideally you'll need to go step by step through each line of code and monitor your program and see what is an unexpected result.

I try to follow first the allocation describe by the function called AllocComptStartEndMin, and you know as usual when you do the allocation of memory for a pointer of "double" for example, p=new double[X]; when you try to see what are the value, for each i from 0 to to X-1 of p[i], (before any affectation), in the debug window, you have in this window:
p[i] in the column "Name" and -6.2774385...e+066 in "Value" column. So when i execute step by step AllocComptStartEndMin, it works even if i>120. So, why when i want to affect value to the pointers i can't affect value for the first pointer when i>120 ( and what is very strange is this value:120, because in my sample RowSize =866 and ColSize=255!)

Hi,

I'm developing an application where you can configure circuits. the problem is after placing the components on the User Interface I've to make connections. these connections are to be represented by lines.

How do we caluclate the path of a line that does not pass through a certain Area . The lines can be only horizontal or vertical. The line has to pass around a certain specified area.

can anybody help me out with this thanks, in advance

Re: Drawing Lines

Christian Graus30-Oct-02 1:19

30-Oct-02 1:19

You're trying to get the circuit to draw itself and therefore not cross ? A basic line intersection algorithm looks like this:

function ccw(p1, p2, p3)
// Slightly deficient function to determine if the two lines p1, p2 and
// p2, p3 turn in counter clockwise direction}
{
var dx1, dx2, dy1, dy2;
dx1 = p2.x - p1.x; dy1 = p2.y - p1.y;
dx2 = p3.x - p2.x; dy2 = p3.y - p2.y;
if (dy1/dx1 < dy2/dx2) return true;
else return false;
}

function intersect(l1, l2)
{
return ((ccw(l1.p1, l1.p2, l2.p1) != ccw(l1.p1, l1.p2, l2.p2))
&& (ccw(l2.p1, l2.p2, l1.p1) != ccw(l2.p1, l2.p2, l1.p2)));
}

That's in JScript, sorry.
