The best bet is to buy another IDE such as CodeWarrior or look for similiar IDEs in the GNU community.
I'm not familiar with the latest Palm OS (past ver 4.1), but the Palm OS is/was based upon the Motorola processor. The apps one writes and places on the Palm are embedded system applications.
If you are only writing Conduits (the apps that handle updating the Palm/PC during a HotSync), then VC++ IDE can do the job for you.
More info?

Falch.NET is a better IDE than Code Warrior because it is cheaper, and looks like VC6. Code Warrior is annoying to use, although it may be just that it was unfamiliar. As Michael said, try searching first, there's a whole section here on Palm articles.

When I am coping/pasting from my c++ program to the notepad the \n's are not coming through.
I get little squares instead of carriage returns.
The string is unicode, but it does not work even when I save-as notepad file as unicode.
Do you know what the problem is and how I can get around it?
ANy help would be greatly appreciated.
Here is my code that puts the string on the clipboard:
void OnCopyButtonClicked()<br />
{<br />
CString strData;<br />
CString strWarningHeader, strErrorHeader, strInfoHeader;<br />
<br />
strWarningHeader.LoadString(IDS_INVENTOR_WARNING_LABEL); <br />
strErrorHeader.LoadString(IDS_INVENTOR_ERROR_LABEL);<br />
strInfoHeader.LoadString(IDS_INVENTOR_INFO_LABEL);<br />
<br />
std::vector<InventorErrorMessageStruct>::iterator iter;<br />
for (iter = m_errorStructList.begin(); iter != m_errorStructList.end(); ++iter)<br />
{<br />
InventorErrorMessageStruct messageStruct = (*iter);<br />
<br />
if(strData.GetLength() > 0)<br />
{<br />
strData.Insert(strData.GetLength(), _T("\n\n"));<br />
}<br />
if(messageStruct.messageType == CErrorListBox::MESSAGE_ERROR)<br />
{<br />
strData.Insert(strData.GetLength(), strErrorHeader);<br />
}<br />
else if(messageStruct.messageType == CErrorListBox::MESSAGE_WARNING)<br />
{<br />
strData.Insert(strData.GetLength(), strWarningHeader);<br />
}<br />

{<br />
strData.Insert(strData.GetLength(), strInfoHeader);<br />
}<br />
strData.Insert(strData.GetLength(), _T(" "));<br />
strData.Insert(strData.GetLength(), messageStruct.message); <br />
}<br />
<br />
if (OpenClipboard())<br />
{ <br />
EmptyClipboard();<br />
<br />
HGLOBAL hClipboardData;<br />
hClipboardData = GlobalAlloc(GMEM_DDESHARE, <br />
(strData.GetLength() + 1) * sizeof(wchar_t)); <br />
<br />
wchar_t* pchData;<br />

Hi
Try this please
Make a new dlg project and place a button and a edit contrrol on it. Do NOT make the edit control multi-line.
Name a str member var for the edit control named say m_strEdit.
Add the following to the button.
OnBottonClick()
m_strEdit.Format("hello world\r\n hello world\n hello world\r");
Update Data(FALSE);
Easy right?
Now copy the contents of your editcontrol to notepad and see what you get.
Answered your own question,,, right?
Best Wishes,

It has been a while, but a think that you need to use "\r\n" (a.k.a. CR/LF)at the end of each line of text that you are copying to the clipboard, not "\n". When you are working with edit controls, or an CEditView derived class, you will find out very quickly that it does not recognise "\n" and does recognise "\r\n".

I want to continually update the data in the edit boxes on my dialog box with data that is generated in a loop. For example:
for( i=0; i<100; i++)
{
m_X += 1;
UpdateData(FALSE);
}
However, when I try this it loops through the for loop and doesn't display the values until it reaches the end of the loop. Thats when it displays 100.
Any help would be appreciated. Thanks

The problem is that the thread that executes your for loop is the same thread that draws the GUI of your app. In order to solve your problem you have to create a workerthread. That thread must have a way to comunicate with your gui.
If your ussing MFC the safe way to do it is passing the HWND of the dialog box or the HWNDs of the controls you want to update and use SendMessage/PostMessage to update their contents.
To create a worker thread ( a worker thread does not handle any UI events, it does not own a window ) you can call:
CWinThread* AfxBeginThread(
AFX_THREADPROC pfnThreadProc,
LPVOID pParam,
int nPriority = THREAD_PRIORITY_NORMAL,
UINT nStackSize = 0,
DWORD dwCreateFlags = 0,
LPSECURITY_ATTRIBUTES lpSecurityAttrs = NULL
);
pfnThreadProc - this is your thread function,it has the following proto:
UINT MyControllingFunction( LPVOID pParam );
pParam - can be anything you want, and it is what you recive in pParam in MyControllingFunction (usualy in MFC a HWND)

Hello All
I have a Win32 C++ application. The parent form has various edit boxes on it and on selection of one of these boxes a dialog box (created using DialogBox) is opened. This dialog box has a date-time picker control on it and allows the user to select a date. Once a date is selected and a button pressed on the dialog box the date is tranferred to the underlying edit box, a child control on the parent window. Now my problem is this... selection of the date works fine and the information is passed to the underlying edit control. The dialog box disappears as you would expect, but when you use the mouse to try and select one of the other edit boxes on the parent form the aforementioned dialog box reappears. This happens several times before I am finally allowed to select one of the other edit controls with the mouse. I have tried changing the focus when the dialog box closes (EndDialog) but the same still happens.
Does anyone have any ideas as to what I might be doing wrong. I am in the middle of writing a small app to try and show what is going on and I'll post this when done, but if anyone has any ideas then their help would be gratefully appreciated.
Cheers

Hi All
This is a small application I have put together to highlight my problem. Basically it consists of a parent window with a button and RichEdit control on it. When you select the RichEdit control a dialog box appears that has a date/time picker on it and another button. Selecting the date/time picker allows you to select a date and on pressing the button on the dialog box the information is transferred to the underlying RichEdit box. The dialog box closes. However, if you then try to select one of the parent window controls with the mouse (the button for instance) the dialog box reappears... Is there something I am (or am not) doing correctly?

It looks as though you're getting an extra EN_SETFOCUS, then. Have you tried using SPY++ to see what messages the RichEdit window is getting, and when?

hello,
i am coding in c++ (mfc) i have addded a list box to my aplication,im having torouble parsing data into my listbox,i have a preparsed buffer contaning the data i want to go into the listbox,but when i try to put it in the list box it comes out as 1 big string,but if i send the buffer data to a edit box it is parsed wonderfully,the buffer is parsed with "\r\n" can i add new lines to the listbox,without doing this again
m_strList.AddString(inBuffer);
or is there a way i can read the data line by line form the buffer and the loop the lines into the listbox 1 by 1?
thanks for your time;)

Hi you are not parsing the buffer just loading it.
Parse it first with a while loop.
Inside the loop load the box.
It may help also to put the buffer contents into a CString the use findrev like
char ch ='\r\n';
while.(condition){
int ix = m_strEdit.ReverseFind(ch);
grab it, stick it.
}

Is there a way to send say a structure to program code and have the code tell you the variable type. This would be helpful when debugging you could do this.
send struct abc to determine_type
determine_type reports
struct abc
value 1 = int and is = 102
value 2 = char * and is = ab\0
value 3 = long and is = 190012
value 4 = char and is = R
end of structure..
This allows you to turn on some form of debugging option and report the types and values within each structure.
thanks

Hi all.
I need to make reports in VC++6.0
these reports are based on database queries or tables..
what is the starting point ? please help and note that I can't use third party components..
any tutorials, samples ?
I know SQL , ADO ,, the problem is just with reports.
thank you in advance 
|
|
|
|
|
The starting point: a LOT of work!
if youre using listview controls to display your results, i have a class that outputs the entire contents of a listview control to the printer, you just add it as a member variable to your views, call a couple of its methods and it does all the work for you. Its written for use with WTL, but you shoulnt have much trouble porting it to be used with MFC (if you are using MFC). If you (or anybody) want it, e-mail me or post here, and ill be glad to send it to ya.
Hope this helps

I need to accept XML formatted data over a socket connection and place the data into a dataset for parsing. The XML data is bracketed by a start character and an end character, but may range from 50 bytes to thousands of bytes. The app will need to be in C/C++ any thoughts
|
|
|
|

You can use expat[^].
pros:
-It is fast
-has a small memory footprint,
-and it comes with source code.
cons:
-it is not a validating parser. So you can't tell if the xml data is valid.
-i don't know if it can read from stream/buffers, i used it only with files.( but you have the source...  )

HI... I wanted to know that can a dll have its own data space? well i guess i am not framing the question properly but what i am interested isn doing is storing some variable/value in a dll that can be persistant i.e i can set it during the first run of my program and then during successive runs read it or modify it .... CAN THIS BE DONE ?

I'm trying to read raw byte data off of a file. The machine which recorded the data stored them as signed 8-bit integers. I need to send the data into a function which accepts doubles. Obviously, I can't read straight into a double pointer. The values would get wrecked. I don't want to read them into a char pointer array and then cast the values into doubles as I read the values into double pointer array. Is there a better way to do this??? Thanks.

No. Read them into a char array, convert them to doubles using a cast and store them in a new double array.
