don't worry André, headers are - most of the time - only declarations.
what can obfuscate the understanding (especially with a dll header) can be function pointers. i suggest you so having a look at the msdn on that topic, of search the web for it (but just tell you it's not so hard and everything will be ok  ).

You don't need 'skills' as in n years experience. You do need to know a little bit about the topic. Search google or CP for writing DLL's. There are some articles here about the topic.
Maybe you should try to call the vendor if they can build the library for you. This wouldn't be a crazy request since you paid for the API anyway.

Why Visual Studio 6 C++ begins slowly editing for multy-project solution?
VS6 sp6.
One project being edited as text in studio -
for inserting new string - works very fast,
(on my P4-3000, 1GB)
but if I edit this project in solution that includes 15 projects,
inserting one line to 200 lined file
takes 1-2 seconds,
it is so long!
why so happen?
How to correct it?
thanks

Is your visual studio linked to some SSC ? Source control ?
If so, you can try removing it, This can speed up loading and editiing speed.

No, it is not linkd to versioning systems,
but only to BoundsChecker.
But with swithed off all options.
This program - can do this slow behavior ?

I have not used boundschecker, so no idea.

Try to remove all the breakpoints in all projects, this is a killer too from some reason.

You might try the following...
Close your project, then delete the .ncb, .aps, and .clw files. Reopen the project and try again.
The .ncb file in particular can grow quite large as you edit code, (and the .aps grows with resources). Therefore the more you add/edit without deleting these file can slow down VS considerably.
Hope that helps.

Hi,
is it possible to store the content (text+format) of a CRichEditCtrl to a variable and serialize it later?
I need this because I have an Array (CObArray) with my class derived from CObject. Each item in this array should store a content of a RichEdit....
Thanks for your help...!

Yes, its possible for serializing the contents of a CRichEditCtrl.
Just get the text and its format in a CString and serialize that CString. While loading get that string and display that one.
If the replies helps you, rate them.

But how can I put the content of a CString to my CRichEditCtrl?
following the part I put my text from CRichEditCtrl to a CString
<br />
static DWORD CALLBACK MyStreamOutCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)<br />
{<br />
<br />
CString *pTempString = (CString*) dwCookie;<br />
<br />
pTempString->AppendFormat("%s",pbBuff);<br />
<br />
*pcb = pTempString->GetLength();<br />
<br />
return 0;<br />
}<br />
void CMyTestDlg::OnBnClickedButton5()<br />
{<br />
EDITSTREAM es;<br />
<br />
es.dwCookie = (DWORD) &m_szRTF;<br />
es.pfnCallback = MyStreamOutCallback; <br />
m_rtfAuswertung.StreamOut(SF_RTF, es);<br />
<br />
}<br />
<br />

I believe you'll want to use CRichEditCtrl::StreamOut(SF_RTF, ...) for this. Simply getting the text via GetWindowText() won't work as it will lose the formatting.

Can someone help me turn this into c++ code. I thought I had it but I keep getting errors. What am I doing wrong? N is an exponent.
Payment = Rate * (1 + Rate)N
-------------------- * L
((1 + Rate)N – 1)
Here is my code:
double payment=(mrate*(1+mrate)* exp (n)/((1+mrate)* exp(n)-1))*l;

Do you mean compiling errors, or errors in the formula ?

Hi,
What do mean saying that N is exponent? Do you mean e^N or x^n?
Where have declared the rest of variables; mrate, n, l?
double mrate = some_initial_value;
double l = some_initial_value;
double n = some_initial_value;
Anyway, if you mean e^N, the code might look like so:
double payment =<br />
(mrate * (1 + mrate) * exp(n) / ((1 + mrate) * exp(n) - 1)) * l;
If you mean x^N:
double payment =<br />
pow(mrate * (1 + mrate), n) / (pow((1 + mrate), n) - 1) * l;

Make sure the numeric constants are floating point values, like:
double payment=(mrate*(1.0+mrate)* exp (n)/((1.0+mrate)* exp(n)-1.0))*l;

Hi,
I want to find out what is the length (or maybe I should say width  of a char* object / string in pixels so I could set the width of column (in List Ctrl) to fit the text length.
Is there any (MFC) function or some kind of trick I can use to find out this attribute?
thanks,
yaron.

check out of thsi function GetCharWidth(...)

How about CListCtrl::SetColumnWidth(..., LVSCW_AUTOSIZE)?

Hi.
I have a program that reads a database and displays its graphics into a CScrollView Instance. To do that it reads records from the database and creates a small metafile for each of it. Finaly, when all those metafiles are created it replays them over the view and displays those that are part of the visible (on screen) window.
I want to create that view invisible (not on the screen) and using the same functions I would like to create all those metafiles. Then rather than replaying them on the display I would like to save them in the disk as EMF.
So far I manage to create the EMF and to replay over it the metafiles. However, I am always getting a part of my image in the saved file and not the whole image (wich be larger than the screen). I do not display the view on the screen thus the CGetClientBox CGetClipBox functions return a zero size rectangle. I 've tried to use functions to manipulate the window extend and the viewport but I am not sure that I understand them.
Can some explain to me what are window origin/extend versus viewport ones? And how can I affect the size of a disk saved MetaFiles?
Thanks a lot
