I have a derived CModeless Class form CDialog class which is used for creating modeless dialogs. I have derived 2 new dialog classes from the CModeless. I have opened the two dialogs since they are modeless. After OnOK of the dialog i must create the dialog again, for both the dialogs. but i am unable to see the dialog when OnOk button until the other dialog is closed.
Can any one tell me the solution for the problem.

Why you can't send WM_CLOSE message to the other dialog before recreating it?
BTW, why it's necessary to have CDialog->CModelessDialog>CXXXDailog/CYYYDialog?

Hi,
How can I make a modeless dialog as child to another dialog using code.
I tried ModifyStyle(0,WS_CHILD) in initdialog but not worked..
How to do that?

Usually you Create() the modeless dialog using the other window as its parent, setting window sizes and such.

You can create a path of the text and then stroke it. You'd do this by -i assume you are using the CDC class- something like:
CDC dc;
...
dc.BeginPath();
dc.TextOut(0, 0, _T("Hollow text"));
dc.EndPath();
dc.StrokePath();
...

I want to be able to recognize when some pane of the statusbar is clicked. I need to know this in my View class which is derived from CView.
One person on this forum suggested subclassing, but didn't know how to go about doing that.
Any ideas?
Thanks

I am getting valid HWND of another SDI application using FindWindow and sending message "WM_COPYDATA". But OnCopyData is not called at the receiving application. What could be the reason for WM_COPYDATA not received?

The first question to resolve is...
- what window are you sending the WM_COPYDATA to?
If you do a FindWindow on an MFC SDI application by windows title you will find you've got the handle of the CMainFrame derived window, not the view window where generally all the interesting I/O happens.
One really clean way of using WM_COPYDATA is to create a "data copy target" window who's sole job is to recieve and process WM_COPYDATA. This window will be invisible and/or off screen so no one can interact with it.
Cheers,
Ash

Thanks for the help!!
I've resolved the problem, I forget to give the size of data to be sent:
cpds.cbData = _tcslen(csData) + 1; .
Also if the receiving application runs in IDE(Running as Admin), and the sending application launched externally(Normal mode), then sending copydata message failed and GetLastError() returns "Access denied".
So the sending application must have same or higher credentials as the receiving application.

Hi,
It seems that in Windows 7 there are some "File Permitions" system.
When my program creates a file on the hard disk, while user A is logged, when user B loggs into widows 7 and runs my program, my program can't get write access to the file which was created by user A.
When I right-click on the problematic file, go to "Properties" , and go to the security tab, I see a list of users that can access the file.
But I need to enable ALL users to be able to access the file.
Any Ideas?
Thanks!

I hope this code works
Instead of using SHGetSpecialFolderPath
use this code:
TCHAR szCOMMON_APPDATAPath[MAX_PATH];
SHGetFolderPath(0,CSIDL_COMMON_APPDATA,NULL,0,szCOMMON_APPDATAPath);
Yes U Can ...If U Can ,Dream it , U can do it ...ICAN

Sorry, it didn't help.
Still can't access a file that was created by my program when it was first ran under other user.
Any other ideas?

Thanks for the link, it was very helpful!
Seems the "User access Control" is a very complicated thing ...
I have a 200,000 lines of code project using many libraries like TinyXML, which create files without using "User access Control" but just doing fopen().
I turned off "User access Control" in Windows 7 and everything works fine.
Hope our customers won't mind to turn UAC as well ...
Those Microsoft guys ... they have nothing to do but to destroy the good Windows XP with stupid features in windows 7 like UAC.

why should the OS allow you to write to a file which you do not own ?
|
|
|
|
|
This is a file my program creates which holds a database, that all users need to have access to it.
Any Ideas?

Hi All,
I have some questions in mind about map and multimap.
1) I know that STL use height-balanced-binary-search tree for MAP implementation but what is actually used for multimap.
2) multimap can also use the same thing with a list in each node for a key. Am I right?
3) How do I give a iterator functionality in a tree structure as in maps and multimaps as in tree it's hard to go through data sequentially.
It will be very helpful if these questions can be answered.
BR,
Akash

In previous versions, when I use dependencies and make a library project a dependency of another project, a link is added to the solution, and I can debug through the main project into the library. With VS2010, making the same dependency has no obvious effect on the solution. When I build the main project, the library is built, but is NOT included in the link. Seems trivial, but need help.
Related. When I want to add a library from another developer, I used to use 'Add existing'. This still works in VS2010, but .lib is not in the drop downs. What is the preferred method for doing this.

Hi Ed,
Those wacky folks at MS have changed the way dependencies are stored and used. Dependencies are now stored in the project file rather than the solution file. Please have a look here[^] - it's explained a bit better than I could, especially the section "Solution Dependencies into Project to project reference."
Hope that helps, at least to dig deeper,
Cheers,
Ash

Hi all,
I want to display a image in a particular control for this i have used CImage Class like this:-
CImage m;<br />
HRESULT hr=m.Load(Header_str);
But my problem is i am not getting how to show it in a particular control like static text box or picture control.
Thanks in advance

CImage class has already defined conversion operator to HBITMAP handle type so you can use in the same way like CBitmap class.See the documentation here
you have even example on hand. 
Life is a stage and we are all actors!

You need to use one of the drawing or 'blitting' methods to render the image onto your device context (window). See the options here[^].
It's time for a new signature.
