Hi.
I can considering to add a new feature to a program I am current working on. I will explain briefly on the program.
I am working on a program that is basically a text editor. it looks and feels almost like Notepad.
I want to add a feature similar that includes a split view. The program will operate using two views. The views are split in horizontally. The top view is the original text. So if the user opens a text file that has "Hello MFC," then the program will always display the original text on the top view. The second view located at the bottom is the modified view. I have a feature in the program where, for example, it will seach a text file and capitalize the first letter of a sentence. Once done, I want to display the modified text in the second view.
I would like to know the best approach for something like that with these key feature:
1) separate and unique saves
--- the user can save *both* files separately. the save features on the menu applies to the original text (top view).
What is the best approach to somehow mark what view the user wants to save? I have two ideas.
1) upon save, the program would save whatever view is *active* (cursor).
2) have a second toolbar for the view #2
I am not sure how to implement either of the above. I tried adding a second toolbar, but the program ignores it (I did not see it).
Thanks,
Kuphryn

You could use the GetDocument of the CView then use the IsModified of the CDocument , to check if the data in document is dirty , note you could use explicitily the SetModifiedFlag of the CDOcument associated with the current View then override the SaveModified function of the CDocument to do the proper action, since the default use a normal prompt to present the user the option of saving the changes.

I am creating a MDI application and I want an icon at the taskbar for every child like Excel has an icon for every workbook. I tried to create a dialog for every child and minimize it, I can activate the corresponding doc, but the icon is not being checked, I also can not minimize the window and at slower systems, you see the dialog appear and "fly away" to the taskbar.
I hope somebody knows a solution.

Danny Springer

If you have VC 7 there is an option for a Doc/View like that. I can't remember the name off hand.

I am not sure whether this is a nice idea, but make each of those mdi children a direct child of the desktop.

Why you think, that it's MDI? It's another architecture, and required another programming. See sources of MFC 7.0 for details.

Use the WS_EX_APPWINDOW style for every window that you want to appear in the taskbar.

Hi.
Microsoft offers an impressive feature in MFC that routes WM_COMMAND and COMMAND_UPDATE messages via command routering using OnCmdMsg(...) in main and a function in doc to traverse through all active view. The drawback, however, is that it only works for COMMAND messages, not any messages.
I wonder if there is a technique similar to the one mentioned above for specific command type such as user commanders (WM_USER_MYCOMMAND, etc). The message map would look like this:
// ON_MESSAGE(WM_USER_MYCOMMAND, OnMyCommand)
Thanks,
Kuphryn

Yeah, this is allowed. People use it a lot in task tray notification handlers. They have a custom message and they use this macro.

Check this out
http://mycrib.kicks-ass.net/project4.gif
I have no idea how to start other then the class declaration.... anyone have any examples on how templates/containers are done, I need something to read to learn this, the book we use for my course doesn't help at all on templates and containers.
Thanks in advance!
BTW If someone has the urge to do what the project asks, don't hesistate, go with the flow, write it and post the code somewhere.

One hint about this homework: The template aspect of your asignment is trivial. Work posIntSet out as a non-template class with maxsize define as a macro somewhere:
#define maxsize 10 Concentrate on the containter issue and when you're done you'll be able to turn your solution into a templatized one with little effort (ask then here, or get some mate to help you.)

I have a modal dialog, and I want to change its title bar before I call DoModal(). (not use the string which is in caption box in resource editor) How can I do this?
Thank you very much!
|
|

Before calling DoModal, the real control is not created yet, only its encapsulating CDialog. So, you'd have to store the new caption in some member variable of the CDialog and later use it (with SetWindowText) in OnInitDialog.

I see. I thought there was a member variable of CWindow which I can change directly. I am wrong.
Thank you, Joaquín.

I am not aware of any CWnd member for this. Add your own and then in
your OnInitDialog() call SetWindowText().

Oops, cannot use SetWindowText() in OnInitDialog. Assert failure since the m_hWnd is null. What should I do?

Hi Lucy,
You should be able to use SetWindowText() on OnInitDialog without this ASSERT. Are you calling it before CDialog::OnInitDialog(); - cause it needs to be after it. I checked the following and it works:
<br />
BOOL CLucyDlg::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);
<br />
SetWindowText(m_strDlgTitle);
return TRUE;
}<br />
Hope this helps, let me know if your ASSERT still shows its ugly head...

I was looking at the SQL Server index adding dialog boxes and came across their ListCtrls that implement a drop down for every row.
I was wondering if there is a sample code implementing similar to that anywhere.
To be clear, I would like to be able to click on a listctrl and have it show a drop down menu from which the users can select.
thanks

Anyone know anything about this message? Is it useful for anything besides very simple horizontal toolbars?
I was thinking of using it to simplify my layout calculations, but it doesn't seem to be smart enough to take window size into account.

Since it retrieves the total size of all of the visible buttons and separators in the toolbar, then the use I think is to construct a pager control, a control where you don't have all the size to show all the toolbar buttons , then you implement a walking right and left arrow to show the next controls on the toolbar ... apart from that I don't known to use it
