Hi again!
I'd like to get a warning window when the file that the user is trying to save already exists so that user could choose if overwrites it or not. Which funtions could I use?
Now my code is:
LPCTSTR sFiltros="Text Files (*.txt)|*.txt|All Files (*.*)|*.*||";
CFileDialog m_ldFichero(FALSE,"txt","*.txt",NULL,sFiltros);
CFile m_Fichero;
char buffer[200];
CString m_snombre;
CFileException e;
ZeroMemory(&buffer[0], sizeof(buffer));
if (m_ldFichero.DoModal() == IDOK)
{
m_snombre= m_ldFichero.GetFileName();
UpdateData(TRUE);
m_Fichero.Open(m_snombre, CFile::modeCreate | CFile::modeReadWrite, &e);
strcpy(&buffer[0],(LPCTSTR)m_sTexto);
m_Fichero.Write(&buffer[0], sizeof(buffer));
m_Fichero.Close();
}
}
Thank you!!
I have no idea

I think the standard CFileDialog class is capable of handling a situation where a file already exists. Have you actually tried with this implementation ? It should notify that the file already exists. At least it does so for me..
But, if it doesn't work so for you, you can always derive a new class from CFileDialog, and override it's OnFileNameOk virtual function. This function is called to validate a filename entered into the dialog box. In this handler, just do a quick test and attempt to open the file. If the attempt fails, the file doesn't exist. If it doesn't, then it exists. According to the return value, display a quick message box with a notification of this issue, and a choice for the user to accept the file overwrite.
I can't provide any ready code, because I have never needed to do this myself. See the CFileDialog documentation for information about the overriddable function.

I found it!
I had to use OFN_OVERWRITEPROMPT flag in CFileDialog function so that it works.
Thank you for your help

Hey everyone,
I have been seeing a bunch of different software that is layed out like microsoft outlook. It has the outlook bar and it basically looks like outlook. Does anyone know how you can create this look? I am not necessarly looking for code, but is MFC used, OpenGL or is there a template out there? I have seen it in 2 different software vendors. Thanks everyone!

Most MFC libraries such as CodeJock and Dundas, have all the code necessary for building Outlook interfaces. (It is usual one of the sample apps they use to show off their toolkits).
I'm sure there are a couple of samples floating around in CodeProject. A search for Outlook Bar here at CP, should bring up a couple.

where can I get codejock and dundas and is this something that you would recommended using? I am just beginning to learn MFC and I thinking of how i would lay out my interface. I thought these interfaces were nice, but I am not sure if this is a good option?
Thanks!

Dundas[^] and Codejock[^]
However if your learning MFC I wouldn't suggest using these libraries becuz I believe they are a couple 100 bux. They are typically designed for professional commercial applications.

Hi guys,
I've been asked to add some RS232 functionality to an app. From what I know RS232 is a protocol which is used over serial connections. I've not been able to find anything on CodeProject to help or explain it anymore.
Does anyone know a good article introducing the subject?
Many thanks,
Simon

Having spent many years maintaining (and expanding/modifying) a network based entirely on serial ports, I know how frustrating it is to find info on this ancient standard. Start here[^], and remember that Google is your friend.
Oh, and if you have to do any programming for it there are a few serial communications articles on CodeProject. But save those for reading after you have a basic familiarity with the protocol - they'll make a lot more sense then.

Hi every body!

My visual c++ sometimes is stubborn and refuses to show the listbox or that little tooltip function prototype thing...but I find after a reboot everything is usually fine.
I think if your using a third-party class(es) you have to actually add the header files to your project before functions prototypes and such will be displayed.
If all else fails you can try ctrl+shift+space...i think that brings up the window in question.

VC++ gets 'confused' after a while. Delete the file <project>.ncb in the same directory as your project file. This file contains the temporary compile results used for Intellisense.

the messagebox function accepts only text values.how can i show int or long values
|
|
|

use CString::Format or any other string formatter to create the string to display in the messagebox.

i have an oracle database and i have a combobox and two edit controls.i want to display record from table into the combobox and the two edit box using CRecordset.how can i do it
|
|

You use a combination of CDatabase and CRecordset objects, with a data source (DSN) on your machine. Basically, the CDatabase connects to the data source by it's name, and then a CRecordset object is created.
You then write a query with the recordset, and execute it. When done, the recordset object contains the results of the query.
See the MSDN for more information.

As a reply to your e-mail: unfortunately no, I cannot code these things for you, I am too busy with my own projects to take on this type of a task.

I am looking for a professional MFC UI Toolkit for the "latest" looks (VS.Net, Office 2003, etc) for a project at work. I have looked at a few like Dundas and CodeJock and would like opinions on these and any other toolkits that developers have used in professional projects. I am specifically looking for good/bad issues with usability, performance, and of course stability.

The CodeJock package contains a whole pleahora of useful tools, gadgets, widgets and sniffely-lifferies. Especially the Professional version is something to recommend: it should cater every need you have.
The downfall of this package is the lack of documentation. It is made with some sort of a half-automatic report creater, and thus most class members and/or functions are just labelled "This is member XXYYZZ of the class YYXXZZ" and nothing more. Such descriptions are not very helpful when trying to determine the necessary functions/members to get most out of the classes.
The Dundas package has a bit more well-done documentation, but doesn't offer as complex interface designs as the CodeJock one. Also, to enable certain features in the Dundas package, you'll have to consult the documentation. The CodeJock version is a bit more plug-n-play style, with the most advanced features left somewhat undocumented.
Both packages I've found pretty stable, and the source code coming with them is most useful in debugging and in creation of derived controls. If I'd need to choose only one, I would choose CodeJock, despite it's lacking documentation.
