if you ownder draw the listbox (with LBS_OWNERDRAWFIXED) you need to add your own MeasureItem method.
It's best if you create your own class for it.

Quick Q.
Are paths expressed in UNC form e.g: "\\network\some folder\file.txt"
accessed faster than when it is explicitly mapped:
e.g: "S:\some folder\file.txt"?
I vaguely remember reading somewhere that this is the case in which your pc does not have to re-find the UNC path everytime there is a connection.

Hi,
Still extremely new to MFC programming, so i am just trying to play around with some of the controls. I made a app that has a few dialogs...which I later put into a property sheet. I was wondering how I could make the window modeless...I don't have the MSDN library so I can't look up how to do this. I hear about a Create() function?
Any help would be appreciated.
Thanks in advance.

<br />
this->m_pPSEstacio = new CPSEstacio("", this, 0);<br />
<br />
this->m_pPSEstacio->Create(this, WS_CHILD | WS_TABSTOP | WS_VISIBLE);<br />
this->m_pPSEstacio->ModifyStyleEx(0,WS_EX_CONTROLPARENT);
this would be useful for creating a child property sheet... (take out the WS_CHILD and the WS_TABSTOP and the last code line...
then you'll get it...
Hope this helps...

Hi,
I got the propertysheet to come up with the correct look of what i want, but its still not modeless.
I am using the code:
sheet.AddPage(&tab1);
sheet.AddPage(&tab2);
sheet.AddPage(&tab3);
sheet.Create (this, WS_CHILD | WS_VISIBLE , 0);
sheet.ModifyStyleEx (0, WS_EX_CONTROLPARENT);
sheet.ModifyStyle( 0, WS_TABSTOP, 0);
sheet.UpdateData(FALSE);
sheet.SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOZORDER | SWP_NOSIZE | SWP_NOACTIVATE);
I thought to make a modal i would have to do sheet.DoModal? how come the create is doing a modal window too? Can some help me be modeless AND give an explanation why?
Any help is much appreciated. THANKS in advance.

If you want it modeless, and still "look" modal, just leave out WS_CHILD in the Create() call. You also won't need any of the lines under this one. This set of lines creates a property sheet that is embedded inside another dialog/window/property page.
Hope this helps,

Hi,
Thanks for all your help.
I did what you suggested, but to no avail. It compiled, but when i went to the app it gave a couple of errors and then popped both windows up. First a blank dialog came up, and then the property sheet came up. Both are closed once I close the blank window. What I have as the code now is:
sheet.AddPage(&tab1);
sheet.AddPage(&tab2);
sheet.AddPage(&tab3);
sheet.Create (this, WS_VISIBLE , 0);
//sheet.ModifyStyleEx (0, WS_EX_CONTROLPARENT);
//sheet.ModifyStyle( 0, WS_TABSTOP, 0);
//sheet.UpdateData(FALSE);
//sheet.SetWindowPos(NULL, 0, 0, 0, 0, SWP_NOZORDER | SWP_NOSIZE | SWP_NOACTIVATE);
BTW, sheet is instantiated like this:
CPropertSheet sheet;
tab1, tab2, tab3 are all Dialogs with base class of CPropertyPage
Am I doing something wrong?
PLEASE HELP.
Thanks in advance everyone.

Your code looks right.
What are the errors that come up? If they are MFC ASSERTs, can you get the filename and line number? From these, you should be able to trace back to see what the problem is. This code should work:
CPropertySheet sheet(_T("Sheet Title"));
sheet.AddPage(&m_Page1);
sheet.AddPage(&m_Page2);
sheet.AddPage(&m_Page3);
sheet.Create();If this doesn't work, then I can't really help any more unless you can find out what's causing the errors.

Hi All,
I'm the first to admit that I'm not to good at the design aspect of programming. So first I was wondering if anyone had any good suggestions on books that I could read that would help out with this topic. All comments are appreciated.
Second, I have a design question. I'm currently writing a program that uses a tabcontrol and I'd like end user to be able to dynamically add/remove/insert tabs into the program, now the problem is I'm not sure of the best way to implement this. I did design one version that used a checked listbox (in an options form) to allow the user to add/remove/insert "items", when the user clicked ok I would check what "items" had a check and create the tabs for them. Where I ran into a problem was that even items without a check need to be kept in memory so that when the user opens the options again they are still there (and it they check them they should be created, and vice versa) the other problem is that each tab has to have some data associated with it. What I did in the first design was have an array that I threw back and forth between the two forms, but that proved to be a very poor design. I'm just wondering if anyone has any better design that I could try I would really love to hear it. Any ideas or simple things to try would be extremely appreciated.
Thanks All!

Hello
I got problems with serial communications, I use workerthread and overlapped io.
Everything works really nice on one computer, but on another one it dont.
ReadFiles overlapped read event doesnt get triggered, Writefile works as it should.
What can be wrong?

2. Yes. The only diffrence is the type of comports. On the nonworking server it's USB serial port, and on the working server it's DigiBord comports.
Well.. Can you please check the connect function, Im not sure if the DCB and Timeoutsettings are correct.

can you check my Connect function anyway?
Since hyperterminal can recieve data from the port, it must be something with my program. And Im really desperate to find out what.

#include <multimon.h>
In one (and only one) file that includes this file, include this line before the #include line:
#define COMPILE_MULTIMON_STUBS
This will enable the use of the multi-monitor functions on any platform (even though Win95 does not support multiple monitors) and degrade gracefully if they are not supported.

the same error ,
I want to tell u that I seached in User32.lib , I find all enum function , but EnumDisplayDevices does not exit at all !!! ,
I MSDN they say that this function exists in User32.LIB !! ,
I wonder if there is another function , instead of this unexist one !!

The code that you posted has the #define line after the #include line, so I assumed that this was the code you were testing.
The function works perfectly. I have used it plenty of times before. Try this:
#include <windows.h>
#define COMPILE_MULTIMON_STUBS
#include <multimon.h>
int WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nCmdShow)
{
DISPLAY_DEVICE dd;
dd.cb = sizeof(DISPLAY_DEVICE);
for(int i=0; EnumDisplayDevices(NULL, i, &dd, 0); i++)
{
}
return 0;
}
