With CFrameWnd I can simply insert status bar by CStatusBar x(this) in OnCreate. But with CWnd it doesn't work. What else have I to do?
|

hi..
firstly you should define indicators names,like that.
static UINT indicators[] ={ID_SEPARATOR};
then you must add "ID_SEPARATOR" to string table on your project.Lastly You must write this code in OnCreate.
m_wndStatusBar.Create(this);
m_wndStatusBar.SetIndicators(indicators,sizeof(indicators)/sizeof(UINT));
it is not enough what you had only created for that.
Good Work.

Why indicators...you don't have to set them when constructing a status bar....the problem is: it's working with CFrameWnd, with CWnd it is not.

Hi,
I am working with the common CFileDialog and I want to set the initial "File name:" editbox to something like "myfile.txt".
I know I can do this with the lpszFileName of the CFileDialog class when constructing, but I would like to set it using the OPENFILENAME structure instead. To be honest, this LPTSTR thing is really bugging me now and I am determined to get it to work...but I do need some help 
I have tried to set lpstrFile, but the app crashes. This is how I have tried to set it so far :-
//it crashed when I did this
CString theString( "This is a test" );
LPTSTR lpsz = new TCHAR[theString.GetLength()+1];
_tcscpy(lpsz, theString);
my_file_dlg.m_ofn.lpstrFile = lpsz;
//so I tried this and again it crashes
CString str("myfile.txt");
LPSTR ptr = str.GetBuffer(11);
my_file_dlg.m_ofn.lpstrFile = ptr;
Thank you for any pointers or guidance.
Michael

Have you looked at the CFileDialog constructor?
CFileDialog dlg(TRUE);
char szFile[MAX_PATH] = "myfile.txt";
dlg.m_ofn.lpstrFile = szFile;
dlg.m_ofn.nMaxFile = sizeof(szFile);
dlg.DoModal();
|
|
|
|
|
That worked just fine.
Now I feel a little humble (i.e stupid) as to how easy the solution was.
Thanks for your help. I think I need to take a break

lpstrFile is also used to return your user's selected file(s). The reason your app is crashing is because the buffer you are supplying is too small. Also, you have to set the nMaxFile member to the same size as your buffer. According to MSDN, the buffer should be at least 256 characters.
TCHAR buffer[256] = {0};
_tcscpy(buffer, _T("MyFile.txt"));
my_file_dlg.m_ofn.lpstrFile = buffer;
my_file_dlg.m_ofn.nMaxFile = 256;

Hi guys,
I just want to know how you attach an existing view when creating a new ChildWnd
When using CMDIChildWnd::Create, it doesn't specify which view it wants to use. Maybe there is another funciton.
Thank you respectfully

Use ShellExecute() or CreateProcess().

Either put the common code in a DLL that both EXEs can use, or have EXE1 post a message to EXE2.

thanks for the help...
I have another question,, say in the menu of program1, i have to following function,,
CPogram1View:: OnFile_CallProgram2_FunctionXXX()
{
//I want to be able to call that specific function of program2..
// how can I do that?
}

Did you consult the documentation for the two functions I mentioned?

I use this code to call one process from other
char* program="project2.exe";
//llama al proceso EcoSG.exe y deja el proceso llamador en espera
_spawnl(P_WAIT,program,program,arguments,NULL);

Sorry if this seems like an easy or elementary question.
I was hoping to make a MFC dialogue program for my students that would present them with a question and use radio buttons for them to answer with. When they had checked their answer there would be a next button to move on to the next question. I can't figure out how clear the question or to add possibly more or less radio buttons after the student clicks the next button. I also need to know how to size the window to match the screens resolution. I don't know if this type of program is even possible using a MFC dialogue program. If not please tell me witch I should use. Any help on this would be great including pointing me in the direction of the correct articles/tutorials. Thank You.

Try setting it up as a wizard instead of a single dialog. Look at the MSDN documentation on how to create a wizard.

The question would be in an edit control. Use SetWindowText() and GetWindowText() accordingly.

Put the maximum number of radio buttons that will be needed on the dialog at design time. Show/hide them as needed throughout the quiz.

Normally, this is not necessary and doesn't fit the profile of a dialog. Anyway, ShowWindow(SW_SHOWMAXIMIZED); in the dialog's OnInitDialog() method will do it.

Radio buttons:
You could try placing the maximum number radio buttons that you would need on the dialog and then use ShowWindow() to show or hide them. You will also needed to use SetWindowText() (a.k.a. WM_SETTEXT) changed the text associated with the buttons depending on the question.
Give the buttons generic name line IDC_RADIO1, ID_CRADIO2, etc...
------------------------------------------
Sizing:
David Crow gave a good answer but I think you might want to go further than just maximizing the window. Search codeproject for resizable dialog box aticles. The reason I am sugesting this is that you may want the controls in your dialog box to adjust there size and position according to the size of the dialog box. Of course for such a simple program you may not care.

I am having problem with the dialog box
with CDataGrid. Once I open the dialog box and
close, I can't open it for the second time.
I think the problem is the way to initialize
and close the dialog box. I am supposed to do
something with CDataGrid?
Thanks in advance.

Hello,
I try to open a dialog with a custom control, calling the finction Dialog.DoModal(). The Function returns imediatly and the Dialog is not shown. (Returncode -1, GetLastError() 0)
If I start a new Dialog based MFC application, I can insert a custom control in the Dialog and the Application runs fine.
Compiler and Linker Settings seem to be the same in both projects.
I can use the custom control in my application in dialogs which are used as view in a splitter window.
Can anyone tell me whots going wrong an what I have to do to get the things running?
Regards
Bernd

Does it have anything to do with the control needing to be registered?
|
|
|
|
|
I don't think so. I steped through the code. The Custom controls classes are registered before the dialog is creaded.
The dialog has a membervariable of the custom controls type and if I step through the Constructor I can see when the Custom controls class is registered.
I steded through the DoModal() and somewhere in CreateDialogIndirect I get a fail. (code not available at the moment)
|
|
|
|
|
By registering, I meant using regsvr32.exe. I've not tried this via code.
|
|
|
|
|
The custom control is implementet in the application and not in a dll or something else.
I can use it the same way I tried it in ma Application in other sample programs without problems.

Iam new to programming in .NET's C++ and I am a little puzzeled on how to perform the following
Objective: I need to have a main PC communicate with to other PC's. The information I need from the additional PC's is what is currently running(i.e. windows programs, etc.) and send a message back. After that I need to have the main PC shutdown or shutdown/reboot the additional PC's and or the main PC
I know I know how to perform the Shutdown or shutdown/reboot.
