hum, i think it terminates when crashing because of a full call stack...

anyway, be careful when handling even which you can potentially rethrow.

I'm curious why you'd want to set the text of an edit control in this fashion. If you are going to hard-code text in the control no matter what is typed/copied into it, there are better alternatives.

For starters:

Set the value in the dialog's template.

Call SetWindowText() in the dialog's OnInitDialog() method.

but this will set the value for the beginning only. if the user modifies the editBox after then, nothing will be done...

That's exactly what his code is doing anyway. No matter what is typed/copied into the edit control, he is hard-coding the control with a call to SetWindowText(). Not only is this a bad design, it results in multiple EN_CHANGE messages.

This is my reason

I use an CString member variable for a listbox to get the selected item data, so if I use a CString member variable for editbox too, I should use the UpdateData(FALSE) to update the changing, then the selected item in the listbox will change and the first one of those items will bw selested.

It's my reason! Smile | :)

Which you shouldn't be. Use a CEdit member variable instead.

Mohammad Rastkar wrote:

There is no valid reason for using UpdateData(). Yes, the framework calls it (i.e., when the dialog is initialized and when OnOK() is called), but calling it explicitly is not necessary.

I'm not sure what this talk of listboxes has to do with my initial comment about edit controls and your EN_CHANGE handler. Confused | :confused:

How to convert ASCII code to character [modified]

Hi All,

I need to add the carriage return and line feed to a string to simulate the new line '\n' before writing it to a binary file.

what is the function I can give the ASCII Code and it returns the equivalant character.

What I need is a function that is similar to chr in Visual Basic

Just write "\r\n" to the file (at the end of each line)

int i=10;      //For Carriage return use 13

There is no need for that in C++. The ASCII code IS the character. That is:

char c1 = '\n'; // c1 = 10
char c2 = '\r'; // c2 = 13

Getting Application Data Directory

Hi All,

How can I find the current users "Application Data" directory ie C:\Documents and Settings\<currentuser>\Application Data\ in VC++ 6.0. I cannot use .NET functions.
Currently I am able to get the same using 'AppData' environment variable like getenv("APPDATA"); but I am looking for any direct functions or other work around for the same.

Thanks,

SHGetFolderPath(NULL, CSIDL_APPDATA, NULL, 0, szAppDataFolderPath);

Great.. I am looking for some thing like this; but the problem I am facing is the SHGetFolderPath and CSIDL_COMMON_APPDATA are mentioned in the MSDN library as being part of shlobj.h and my shlobj.h contains neither of these declarations. Is it the part of Platform SDK?

Why you wanted to do this ? Service is supposed to start in back ground and work silently.
