Your kiding me, that actualy worked? Please explane why.
From MSDN:
Type double
Double precision values with double type have 8 bytes. The format is similar to the float format except that it has an 11-bit excess-1023 exponent and a 52-bit mantissa, plus the implied high-order 1 bit. This format gives a range of approximately 1.7E–308 to 1.7E+308 for type double.
Microsoft Specific —>
The double type contains 64 bits: 1 for sign, 11 for the exponent, and 52 for the mantissa. Its range is +/–1.7E308 with at least 15 digits of precision.
END Microsoft Specific
Ok I probubly just broke the law. But I need to know.

Hello,
in MDI project,i want to hide the main menu (IDR_MAINFRAME) when i press F11 and show the menu when a press F12 , i already try
SetMenu(NULL) to hide it, and it works, but i don't know how to show the menu ?
help please
thx in advance
|

|
|
|
CMenu *pMenuOid = SetMenu(NULL);
//............................
//restore it!
SetMenu(pMenuOld);
I am seeking...
For what?
Why did you ask me for what? I don't know!
|
|

thx
but it don't works, SetMenu(NULL) return a BOOL and not a CMenu.
i try
CMenu *pMenuOid = GetMenu(NULL);
SetMenu(NULL)
and to restore it :
SetMenu(pMenuOid);
but when i restore i have a Error message (Debug Assertion failed)

Dear all

Object 3:
dddddddddd
for(int i=0;i<3;i++)
{
xxx.Find("Object [i]:");
}
Can someone tell me how to code the integer part,[i], in Find method.

With a second CString and CString.Format.

Hello all!
Here is some "strange" behaviour of CreateProcess (or winword, I don't know)
I wanted to launch winword from my application and be notified when the user close the session I opened, so I used CreateProcess and WaitForSingleObject .
Here is the code sample from MSDN:
<br />
SECURITY_ATTRIBUTES sec;<br />
sec.bInheritHandle = FALSE;<br />
sec.lpSecurityDescriptor = NULL;<br />
sec.nLength = sizeof(SECURITY_ATTRIBUTES);<br />
<br />
STARTUPINFO si;<br />
::ZeroMemory(&si, sizeof(STARTUPINFO));<br />
si.cb = sizeof(STARTUPINFO);<br />
PROCESS_INFORMATION pi;<br />
<br />
if(::CreateProcess(NULL, <br />
"C:\\Program Files\\Microsoft Office\\Office\\winword.exe / / C:\\STPMesagElec.doc", NULL,NULL, TRUE, NORMAL_PRIORITY_CLASS, NULL, NULL, &si, &pi)) <br />
{<br />
WaitForInputIdle(pi.hProcess, 3000);<br />
WaitForSingleObject(pi.hProcess,INFINITE);<br />
}<br />
else {<br />
int err = GetLastError();<br />
::MessageBeep(0);<br />
::MessageBox(NULL, "CreateProcess() failed.\nCheck Path for WinWord.Exe.",<br />
"Error", MB_SETFOREGROUND);<br />
<br />
return;<br />
}<br />
<br />
::CloseHandle(pi.hThread);<br />
::CloseHandle(pi.hProcess);<br />
Now, the result:
- If I use CreateProcess as above, but without the 2 slashes, it works only when there is no other instance of Word already opened; if a session already exists, WaitForSingleObject doesn't block anymore
- If I use CreateProcess with the two slashes, it works just as I need it.
I noticed that with at least one of the slashes, CreateProcess creates a new instance of winword.exe, else it opens a new document in the already existing process.
Also, with other applications (eg Notepad or even Excel), it works fine without the slashes.
Do you think that this is abnormal behaviour?
Why it needs the slashes? (i discovered this by pure luck, it isn't documented anywhere)

Winword does check if it is already running. It registers in the ROT as an automation server. If You create a second instance only a new document is created because winword knows about its predecessor.
For the second slash I dont know but this can fool the command line parser of winword so it creates always a new instance regardless of previously existing ones. But there should also be a documented switch there (/automation ???)

Hi all!
I created a class derived from CStatic (so I can use a specific font, colors, and so on) but I want to associate a callback function when I click on the control (like a norma button).
Can I do this or do I need to derive from CButton instead ??
Thanks

It must be possible. Search in CodeProject for the CHyperLink calss from Chris Maunder, I think it is an enhanced (and clickable) CStatic.

Yes, you can do it, map the BN_CLICKED message for it, but make sure you have set he SS_NOTIFY style in the resources otherwise you will not get it.

dear all,
how do i insert a newline character in an multiline MFC textfield (CEdit)
i tried \n\r but it shows 2 junk characters in the textfield
|
|
|
|
|
Make sure the edit box has the 'multiline' property checked, and I think it's \r\n.

From Mike's FAQ[^] :
4.12: How do I create a newline in a multi-line edit control?
Use "\r\n" to create a newline. If you use "\r" or "\n" or even "\n\r" you'll see little blocks in the control.

got the solution:
FileDialog dlg(TRUE, NULL, NULL, OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT, "Exe Files (*.exe)|*.exe|All Files (*.*)|*.*||", this);
dlg.m_ofn.lpstrTitle = "Select the File";
if(dlg.DoModal() == IDOK)
{
m_strExtractorPath = dlg.GetPathName();
}

Hi !
I'm not sure that's what you want but you can use the CFileDialog (take a look at the help) from the MFC. You can specify some parameters (load or save file dialog, the file extentions, ...).

your right... thnx

Hello,
I've created an ActiveX control and added CColorPropPage to go with the Back- and ForeColor StockObjects, this gives me a propertypage with 16 colors but I want more! Are these 16 colors by design or is it because I have an old platform SDK thus using old dlls? Also, I want to get notified when a color changes, does this mean I have to change a Stock property to a Custom property or can I get notifications from a Stock Property?
Thanks in advance,
van Padoea.

Taken from Microsoft's .NET help:
--------------------------------------------------------------
An unsuccessful attempt was made to form a qualified name.
For example, make sure that your code does not contain a function declaration where the function name begins with ::.
The following sample generates C2825:
// C2825.cpp
typedef int i;
int main() {
int* p = new int;
p->i::i(); // C2825
// try the following line instead
// p->i::~i();
}
--------------------------------------------------------------
Can someone be so kind and explain this to me in plain English ?

Are you trying to call the constructor here? That happened in the previous line...

No, it's not my code.
It's a sample given by Microsoft, and this example should illustrate the error, which I have no idea what it really is.
Anyway, ignore the example if you wish. My question was actually- what this error means as I get this error on a totally different case.

I'm searching for a handle leak that's driving me crazy...
http://www.codeproject.com/useritems/HTMLCtrlSample.asp[^]
And meanwhile the customer could work with the new program version...
So I would like to know how many handles leaked can a Win2k Professional OS support.
Any idea?
