Are the child dialogs modal or modeless?

if your child dialog are Modal.. then you must be calling like this..
CChildDlg chdDlg;
chdDlg.DoModal();
As the DoModal call is Blocking Function.. thats mean your Parent dialog will be blocked till you childDialog is Visible/running.. so if you want to perfrom task after closing of Child dialog you can write after the DoModal call

"Child dialog" is nearly always used in a general sense, hence the question.

Hi ,

I can't do that in WM_Destroy as it sends assert failure as the parent dialog is about to be closed because i need to do some manipulations on class member of Parent Dialog.
I make an object in the OnDestroy event of child to modify Parent's label control.But when destructors are called child destructor is called first and in that destructor (Parent object was created so it causes assertion failure).
If any other method to solve this please send some code snippet for that
Thanx alot

I have two questions really bothers me.
1. Is it possible to have .Net assembly with global functions so that I can add reference and use them in my application by ::globalfunctions?
2. I have one small solution with two projects: one to create the dll and the other is to consume it. In the application, I can see the intellisense recognize the member in the namespace. But when I compile, I got error 2039 "something" is not a member of "namespace".
Any help will be greatly appreciated.

i'm just getting into programming and for one of my projects involves opening a file, but if it doesn't exist it is not supposed to create one, but rather output an error message. in some cases, if i give it a file location that doesn't exist, it outputs the message and doesn't create a file, but most of the time it creates the file and doesn't output the message. why is this?
any help would be much appreciated
thanks

What function are you using?
You may try PathFileExists()

If you're using MFC CFile class if you will pass only CFile::modeRead it won't create it if it doesn't exist (Open function).
If you're using fopen pass only 'r' to mode parameter and the function will fail if the file does not exist.

right on, thanks for the help guys. saved me another day of tearing my hair out, haha.
muchas gracias

if u use CreateFile()
Specifiy the create dispozition paramater: OPEN_EXISTING;
if the function return INVALID_HANDLE_VALUE then it does not exist or u can use GetLastError() and FormatMessage() to see the exact error returned  hope this helps

Another way for you knowledge:-
You can also use
CFile::GetFileStatus(CString filename,CFileStatus status) a static function
returns false if it doesnt exist and then return from your function.

Which Api/Class are you using to read/write File.. as these api contain flags... which can return ERRROR is no file Exist by that name on the specified path.

If there is not enough memory, new will throw bad_alloc exception for you anyway and you will never even get to your NULL test.
My programming blahblahblah blog. If you ever find anything useful here, please let me know to remove it.

> If there is no memory how can i throw an exception?
Never *ever* throw exceptions which allocate memory dynamically (or dynamically allocate the exception object itself), when you are out of memory. Things may happen to your application which you may not recover from if you had a thousand catch clauses (I love paraphrasing lyrics by the way  )
As Nemanja says, "reuse" the exception which new provides for you. You'll be much better off that way.

At least in my case. What I am trying to do is to obtain an icon from an executable and to add it among with exe name to the report-styled list control.
<br />
if(ExtractIconEx(str,0,NULL,NULL,0) > 0)<br />
{<br />
ExtractIconEx(str,0,NULL,&hIcon,1);<br />
m_plistIcons->Add(hIcon);<br />
}<br />
else<br />
m_plistIcons->Add(m_hIcon);<br />
What I get is while every run the handle is different and after the loop ends image list contains 37 entries the only icon which is applied to absolutly all list items is the first added to the image list.
Image list is being attached to list control using this line:
m_ProcList.SetImageList(m_plistIcons,LVSIL_SMALL);
I am quite sure I'm doing something wrong. I just dunno what.

Maybe it depends on how you add the items to your list control. By default the CListCtrl assumes to use image 0 for all items. You have to specify for every item which image it should use.
