Im trying to get a small bitmap I have to appear on my toolbar, not to be pushed like a button or anything, just a picture. I have created a "dummy" button on my toolbar and called it ID_STATIC_DUMMY. This is the code I have:
CToolBar m_wndToolBar;
CStatic m_static;
CRect rect;
int nIndex = m_wndToolBar.GetToolBarCtrl().CommandToIndex(ID_STATIC_DUMMY);
m_wndToolBar.SetButtonInfo(nIndex, ID_STATIC_DUMMY, TBBS_SEPARATOR, 25);
m_wndToolBar.GetToolBarCtrl().GetItemRect(nIndex, &rect);
if(!m_static.Create(NULL,WS_DLGFRAME | SS_CENTERIMAGE | SS_BITMAP | WS_VISIBLE, rect,
&m_wndToolBar, ID_STATIC_DUMMY))
{
TRACE(_T("Failed to create static\n"));
return FALSE;
}
CBitmap myBitmap;
myBitmap.LoadBitmap(IDB_BITMAP_STAR);
m_static.SetBitmap(myBitmap);
It works correctly except that it doesnt display the correct bitmap. I cant even make out what it puts there but it does put something there. Whats the problem???

It seems that your bitmap gets destroyed when myBitmap goes out of scope. Make it a member or call myBitmap.Detach().

I have a CString. It contains multiple #'s that break it up. Now i want to get each piece of text seperately between the #'s. For example:
Jake#Caroline#Mark#Anthony#Sid#
The string ends with # but doesn't start with # (although you can presume otherwise because it can be changed).
Hows the easy way to do this? (preferably the MFC CString way  )
Thanks
P.S.: i'll stop hasssling u ppl now lolz, i'm working on a program thats why i was asking so many questions hehe.

The C way would be with strtok, but otherwise, you'd use CString::Find, which allows you to find the first instance of a substring starting from a specified position, and CString::Mid which allows you to pull a substring out of the middle.

try this:
CString text = "Jake#Caroline#Mark#Anthony#Sid#";
CString name;
int index=0;
while (AfxExtractSubString(name, text, index++, '#') {
if (name != "") {
// do something
}
}

One way to do is to copy the CString to a char buffer and strtok() your way through the buffer.
(Btw, if you're using the CP forums to get canned answers to your schoolwork, you're only hurting yourself.)

Can you tell me how I copy a string to a char buffer? Sorry if this question is a bit stupid...

The only stupid question is the one not asked! Here's how:
char szBuffer [LARGE_ENOUGH_TO_HOLD_STRING];
CString strMyString = "Whatever";
szBuffer [0] = '\0';
if (strMyString.GetLength() < LARGE_ENOUGH_TO_HOLD_STRING) {
strcpy (szBuffer, strMyString.GetBuffer (0));
strMyString.ReleaseBuffer();

Hi All,
I was just wondering about something that has been bugging me ever since I saw something like this in Java. In practice, which type of statement would be more preferable if you were to call a class function inside the same class in C++?
class Object {
void func1() { this->func2() }
void func2() {}
};
or
class Object {
void func1() { func2() }
void func2() {}
};
Is there any performance differences between the two? 
Also, I apologize if this code might look wrong. I just wanted a conceptual opinion.

There's no performance difference. IMHO, you only need 'this->' when one of the method parameters has name colliding with name of another data member. In the example below, the parameter 'foo' hides the member 'foo', so you need to explicitly qualify it with 'this'. Of course, you can rename the SetFoo parameter 'foo' to 'theFoo', in such case there's no need for explicit 'this'.
class obj
{
public:
void SetFoo(int foo) { this->foo = foo; }
int GetFoo() const { return foo; }
private:
int foo;
};

I'm new to c++ and wanted to implement a few api calls into a test project. Unfortunately, every call fails w/ the unresolved external symbol error. Why? I include windows.h and give the functions all required parameters. Here's a sample-->
#include <windows.h>
int main()
{
HWND hwnd=NULL;
ShellExecute(hwnd, "open","http:\\www.google.com",NULL,NULL,SW_SHOWDEFAULT);
return 0;
}
and i receive these errors-->
main.obj : error LNK2001: unresolved external symbol __imp__ShellExecuteA@24
Debug/load.exe : fatal error LNK1120: 1 unresolved externals

from MSDN:
Header: Declared in Shellapi.h.
Import Library: Shell32.lib.
You've obviously got the header, try adding shell32.lib to your libraries list in the options for your project.

You need to link your application with Shell32.lib.

Hi all,
I want to know, What is Access 2000, DAO version ?
Because, in one of MSDN article about DAO:
[B]
"This article describes how to create an Access 2000 (Jet 4.0) database in Visual C++ 6.0."
and other part of that article:
"DAO 3.6 is installed with Office 2000."
Does Access 2000 install DAO 3.6 and DAO 4.0 ?
For using DAO 4.0 in my programs, i must write below source code ?
AfxGetModuleState()->m_dwVersion = 0x601;
My month article: Game programming by DirectX by Lan Mader.
Please visit in: www.geocities.com/hadi_rezaie/index.html

The problem is that MFC supports only dao 3.0 but when you install Access you will have the 3.6 version of DAO.
Okey, when tou initialize the engine of dao with afxdaoinit mfc wil set access 3.0 but you can use dao 3.6 that you have in your machine because it was installed by access 2000, and for that you can use it you must set AfxGetModuleState()->m_dwVersion = 0x601...
That's it.
If you need a better explanation please looking for a issue of MSJ of year 2000.... (I think that in Febraury or march) where Paul Dilascia explain the problem....

Access2000 installs DAO 3.6 and Jet 4.0 - not the same thing. DAO is a set of COM objects that let you use the Jet db engine (which Access2000 is a front-end for).
DAO and Jet are related as ODBC ans SQL Server is - if that makes it any clearer

I wanted to get the text from an item in a listview control on my main dialog window but it gives me a debug assertion error:
CMyDlg dlg;
m_pMainWnd = &dlg;
int nResponse = dlg.DoModal();
if (nResponse == IDOK)
{
CString Data = dlg.m_MyListcontrol.GetItemText(0,1);
}
Any ideas why??
The item in the list control exists, no doubt about that but is it maybe because the main window has already closed or something?
How do i do this?
Thanks
Kuniva

You are checking the value after the dialog has been destroyed hence all child controls are also destroyed. GetItemText does a SendMessage to the hWnd of the ListControl which no longer exists hence you get the assertion.
Save the value on the OnOK handler of the dialog to a CString member variable and then you'll be fine.
<br />
CMyDlg::OnOK()<br />
{<br />
m_strData = m_MyListControl.GetItemText(0,1);<br />
}<br />
<br />
<br />
CMyDlg dlg;<br />
m_pMainWnd = &dlg;<br />
int nResponse = dlg.DoModal();<br />
if (nResponse == IDOK)<br />
{<br />
CString Data = dlg.m_strData;<br />
}<br />
<br />

Good explanation.

Oops, don't forget to call the CDialog::OnOK after you save the value - in my prev post.
