I have a sort of Service which resides in a dll. Whenever something happens in the system the functions from this DLL are called. Now my question is, i am trying to make a sort of control panel thing where i can set options that the DLL code will abide by, and when the control panel is closed these options will be saved. Also, the DLL code must be able to pass information to this control panel to display some status and other data. My question is, how can i let these communicate? Do i just use FindWindow() from the DLL code to get the window handle and access it that way? But i thought maybe this is too... heavy or whatever i should call it, like if the DLL functions are suddenly called a lot by the system then it would always do a findwindow first, wouldn't that slow things down too much? Anyways, i don't know. Thats why i'm asking 
Thanks in advance

Hello!
I have an edit control and a checkbox. The user can choose if the edit box displays only stars (= password box) or the plain text.
I tried this:
if(m_bStars == FALSE)
m_pEditPw.ModifyStyle(ES_PASSWORD, 0, 0);
else
m_pEditPw.ModifyStyle(0, ES_PASSWORD, 0); m_pEditPw is a CEdit and m_bStars is the bool flag of the checkbox. The function calls UpdateData(TRUE) before trying to change the edit box style. I checked the m_bStars variable, it gets updated correctly each click.
But unfortunately the box doesn't change. It always shows plaintext, the ModifyStyle function doesn't seem to work? I tried a RedrawWindow after the modify, but it doesn't change anything.
What am I doing wrong?

You use the EM_SETPASSWORDCHAR message to change the password style. However, I tried this a few days ago and it doesn't appear to work right on XP  (search for my post in this forum)

According to MSDN CEdit::SetPasswordChar(0) will cause an edit control with the ES_PASSWORD style to display plain text.

Hi,
Am trying to implement the Customdraw notification on a CListCtrl within a form-based application. Every time I try to compile I get this...
__________________________________________________________________________________
Linking...
PunchView.obj : error LNK2001: unresolved external symbol "public: void __thiscall CPunchView::OnCustomdrawList(struct tagNMHDR *,long *)" (?OnCustomdrawList@CPunchView@@QAEXPAUtagNMHDR@@PAJ@Z)
Debug/Punch.exe : fatal error LNK1120: 1 unresolved externals
___________________________________________________________________________________
The demo files I'm working on from the "Neat Stuff to do in List Controls Using Custom Draw" article on this site compile just fine. I know I must be missing something simple - I just don't know what!!
Any help much appreciated,
Simon

Add the cpp file that contain this function, or if the function comes with dll, add the lib file into your project.
In FileView, click right button on YourProject Files and select Add Files to project.

Thanks Alexs,
Your advice helped me solve the problem: the function was in the file but not declared as a member function.
Thanks for taking the trouble to help me.

Hi,
i have two dialog boxes, how do i access a member variable of one dialog box from the other one.The first one is closed using EndDialog and the next dialog box is made to pop up using DoModal();
Thanks

Dialog A should have a pointer to dialog B. In dialog B, provide accessor/mutator methods to manipulate its members. Then do something like this in dialog A.
ASSERT (pDialogB != NULL);
int foo = pDialogB->getFoo();
...
pDialogB->setFoo (foo);

Hi,
How can I develop an Active X control, dialog based with some MFC controls (CEdit, CButton, CStatic) and some Active X controls (extern).
In the Wizzard, I just make an active x control wich subclass BUTTON or STATIC or SCROLL, but I want to integrate many controls.
thank you.

Hi,
I use the ofstream.write (......) function in my code to generate log files from Ethernet traffic. Everything works fine but if I "Stop" my application, the last data is not being sent to the log file but will remain buffered somehow and show up in the log only after I use the close() method.
To prevent that I used the flush() method when I "stop" my application (before closing the files)
My question is,
Is there a way to force the ofstream to automatically flush the buffer to the file whenever I specify the write function?
Thanks,
Shay

It looks like the control can't be created - perhaps the OCX been deleted/moved from the problem machine?

I have an HP DesignJet 5500PS which has WEB pages built into the printer that lets the user control setup and view job status, material status, etc. Having never done any HTML or WEB design or access work in the pass I would like to access the different WEB pages from a program not just to view but to also acquire different fields of information and maybe even change fields from a program.
I have taken the source code (HTMLCTRL) provide on a number of different sources an implemented a dialog where I can view the WEB pages but now I want to actually access some of the data on those WEB pages. Remember I can’t change any of the printers WEB pages, only the code I write. So if anyone can give me some direction as to “how to” I would appreciate it.
NO .NET or VB Please, just Windows, C++ and MFC
Many thanks in advance

I had a problem a while back using STL. I had some code that used the old fashion CTypedArray etc. and I included some STL code. I started getting all sorts of conflicts with <fstream.h> and <fstream>. The new STL code used namespace std and the others did not use a namespaces. There were significant differences between the old fstream.h and the templated one. How do you resolve this with a one or two line configuration?

Post a specific example of the code and what you want to accomplish.

I don' have no code suh'. If I did it would fill the message buffer on CP pretty darn quick. Think big big project.
My question is: What is it in namespaces or use of STL in general that would cause conflict with the use of old fashion <fstream.h>. I tried replacing all the <fstream.h>'s with <fstream> (the STL version) There are some differences in the member functions, I tried to scope the namespace properly and it still didn't work.

Hi,
Can someone explain me or has a class for a small ComboBox ?
I would like to have a ComboBox with a little Edit Box, a small button, a small scroll button,...
Like in these exemples :
http://www.codeproject.com/listctrl/xlistctrl.asp
http://www.codeproject.com/docking/ToolbarWithCombo.asp
I tried to understand these prog, but can't understand !
(Sorry, I'm just a student !)
Thanks a lot.

The height of the button on a combo box (and the minimum height of the box as a whole) is determined by the size of the font used to draw text in the comb. Change the font to a smaller one & you get a smaller combo box.

thanks,
wow, it seems so easy !!!
but I've tried and don't know how to do that.
I've done :
CFont f;
f.CreatePointFont(80,"Arial");
m_cbTest.SetFont(&f);
But it doesn't work.
Can you help me again ?

Two things - first, make sure the CFont object is a member variable of your dialog class, not a local variable (else it'll be deleted when it goes out of scope). Second, an 80pt Arial font is probably large enough you won't notice the change... Besides, you probably aren't sizing your controls in points anyway. Try this, adjust as necessary:
m_font.CreateFont(-8,0,0,0,0,0,0,0,0,0,0,0,0,"Arial");
This will create a font with a total height of 8 pixels - the combo box will be slightly larger because of borders and such.
