good question.
But yes they are the same number. I made sure they were.
The number is 104, and I made sure that the number is the same.
any other ideas
Thanks!

Woo Hoo!
I finally understand it!
Turns out that I need to be using the RT_GROUP_ICON because I'm not using hardware-dependent icons. I was then able to try other resource types and successfully got the information I needed.
Thanks Guys! I really appreciate the help!

I want to draw lines on a dialog in MFC(SDI) application.
Currently I am doing the same thing in OnDraw function of my CAppView by using the code.
pDC->MoveTo(x1,y1);
pDC->MoveTo(x1,y2);
Now I want to draw these lines on a dialog. Is it possible. Can I use the same functions. If yes, Then what would I use in place of pDC to call these functions.
If not refer me other ways of doing so.
Reply me soon

pDC->MoveTo(x,y)
That is the startpoint where you will start drawing your line. I don't see why you move 2 times to the same place.
I think you want something like this
pDC->MoveTo(startpointx, startpointy);
pDC->LineTo(endpointx, endpointy);
so you needed LineTo with a EndPoint of course
i hope this helps
Greetings

Do the same thing you did in OnDraw() only do it in the dialogs OnPaint().
Trust in the code Luke. Yea right!

Hello,
this:
CFileDialog dlg(FALSE);
CString fname = dlg.GetPathName();
const char* szBuffer = fname;
int i = sizeof(szBuffer);
CFile f;
if( f.Open ("F:\\test\\id.txt", CFile::modeWrite ) ){
try{
f.Write(szBuffer, i);
f.Close();
}
catch (CFileException *e){
AfxMessageBox ("Error!");
e->Delete();
}
}
}
...if you type in "rtf" it insert in my "id.txt" file:
F:\r¼ÖA Q a ¼ºÜþ4 ýýýý€*0 *0 ¬)0 Ì(0 ÍÍÍÍÍÍÍÍØ(0
why??
Thanks, Mark

You might want to try:
CFileDialog dlg(FALSE);
CString fname = dlg.GetPathName();
const char* szBuffer = fname.GetBuffer(0);
int i = fname.GetLength();
CFile f;
if( f.Open ("F:\\test\\id.txt", CFile::modeWrite ) )
{
try{
f.Write(szBuffer, i);
f.Close();
} catch (CFileException *e)
{
AfxMessageBox ("Error!");
e->Delete();
}
}
fname.ReleaseBuffer();

Thanks, Mark

Try:
CFileDialog dlg(FALSE);
CString fname = dlg.GetPathName();
char* szBuffer = NULL;
int i = 0;
CFile f;
if( f.Open ("F:\\test\\id.txt", CFile::modeRead ) )
{
try {
i = f.GetLength();
szBuffer = new char[i];
if(szBuffer != NULL)
f.Read(szBuffer, i);
f.Close();
} catch (CFileException *e)
{
AfxMessageBox ("Error!");
e->Delete();
}
}
if(szBuffer != NULL)
delete [] szBuffer;

I must cast the szBuffer to a CString type:
CString csPath = szBuffer;
is this allowed?
Thanks, Mark
|
|
|
|

Actually, this implicitly casts szBuffer to a LPCTSTR, which CString has an assignment operator for.

Nice, but still generates test.pmjyyyxx as output????
Thanks, Mark

CFileDialog dlg(FALSE);
dlg.DoModal();
CString fname = dlg.GetPathName();
const char* szBuffer = fname;
char s[128];
int i = lstrlen(szBuffer);
CFile f;
if (f.Open("F:\\test\\id.txt", CFile::modeWrite | CFile::modeCreate) == TRUE)
{
try
{
f.Write(szBuffer, i);
}
catch (CFileException *e)
{
AfxMessageBox ("Error writing!");
e->Delete();
}
f.Close();
}
if (f.Open("F:\\test\\id.txt", CFile::modeRead) == TRUE)

Hi
Let's say i have a CString:
CString mytext = "1G-I8-EJ-89-B6";
I want to have a little security and i thought of substituting some characters with some others within that CString.
Like for example:
'0' to 'J'
'1' to 'H'
'2' to 'A'
I thought of making a two-dimensional char array.
'0' 'J'
'1' 'H'
'2' 'A'
'3' '9'
....
is there a short way to write this?
instead of using mychar[0][0]='0';
mychar[1][0]='J';
and how can i easily convert an int to a char?
Best regards
Jens

hi,
try this one
in your header file declare:
<br />
extern char Array2ofChar[2][10];<br />
in the correspondending c/cpp file write:
<br />
char Array2ofChar[2][10]=<br />
{{'0','1'},<br />
{'A','2'},<br />
...<br />
};<br />
that should do the trick.

Hi
I've been searching a long time for a code sample that could show me how to create a Virtual Serial Port with C++ under Windows 2000.
I need to design a app that creates a virtual serial port and then all the data that is sent
to that virtual serial port needs to be transformed and redirected to a serial port on this PC.
Thanx!

How do i convert a "unsigned char[8]" 8 byte array to a long. Please help. Many thnx in advance.
|
|
|
|
|
|
thnx for the reply, but that's not exactly what i'm looking for. I solved it by using a union.
union x
{
unsigned char[8] ucaByteArray;
double d;
};
Because it's a union, they share the same address space, which means the content of all the 8 element can be accessed directly by the double. This is precisely what i want, and it works great.

Hi,
If you are using VS.NET you can use CDHtmlDialog class.
The CDHtmlDialog class is used to create dialog boxes that use HTML rather than dialog resources to implement their user interface. CDHtmlDialog can load the HTML to be displayed from either an HTML resource or a URL.
CDHtmlDialog can also do data exchange with HTML controls and handle events from HTML controls, such as button clicks.
