As the others pointed out, you are returning an int - probably without knowing it.;P
You definitely need to return a CString, not CString& or *CString. You cannot return anything local to your function, as it needs to exist after your function has terminated.
Your first parameter should be a const CString&: As you are only ever reading it, so you can promise that to the compiler and let it optimize your code. It should be a reference, as there is no point in making a temporary copy of the CString just for this call (as the normal call-by-value does). Yes, I know about CString doing refernce counting, but this is beginner level.
Third, your variable names could be longer and more 'telling' about their use. But that is purely personal style.

Hi,
In my application i have this:
HBITMAP hImage;
hImage = (HBITMAP)::LoadImage (AfxGetInstanceHandle(), "c:\\TEMP.bmp", IMAGE_BITMAP, 0, 0,
LR_LOADFROMFILE |LR_CREATEDIBSECTION );
DeleteObject(hImage);
These statement will increase the memory usage by 28 KB.
Size of the "temp.bmp" file is 360KB.
Could any one tell me why is it so?
Regards
Neha

How are you measuring this?

Using window task manager mem usage for that application.
|
|
|
|
|
the value displayed in the task manager is not correct at all!
Don't try it, just do it!

Is there any proof for that?

The best you could hope to come from TM is to show the size of the address space that is in use, not the amount of that address space that your program is actually using. Perhaps you are confusing address space with program size.

I am talking about the Mem usage column in the processes tab.
I think this represents the memory usage by the application.
|
|
|
|

this is not the answer to your question, but for loading a bitmap from the disk, you dont need to pass the hInst to the function!
Don't try it, just do it!

Still no difference..
One more strange thing is when some of function been called, It will increase the memory usage by 4KB.Those function don't allocate anything......

How do you know? When you call a function that is not your own, are you sure of what it does, or doesn't do, behind the scene?

If you execute that code 100 times does it increase the memory in task manager by 2800 K?
If yes, then it is a memory leak.
If no, it is just increasing the process address space one time to reflect the additional library code you used.
|
|
|
|
|
Yes,It increases by 2800K........

Write a program that doesn't do anything
main()
{
return 0;
}
Now see how much memory this takes in task mgr. According to you it shud take 0 bytes!!

hi,
is someone familiar with manipulating PE/COFF Files. I need to add a DLL into the import Table, but that's a damned hard job. One of my problems is, that i can't create a valid Relative Virtual Address (RVA). I need help.
Thanks in advance!
|
|
|
|
|
what is the problem with it?
Don't try it, just do it! 
|

There are a few problems.
Number 1: You can't simply add as much DLL Entries as you want into the Import Table, without changing the rva's of the following sections.
Number 2: You have to find a place in the .exe/.dll file which is mapped into the memory
Number 3: The place must be big enough to hold every needed information, such as the name of the dll you want to add
Number 4: You must calculate a valid RVA for the position where the name of the DLL is located.
Number 5: ... Number 4 seems not to be the last point to pay attention for, because if you fixed every mentioned problem, it still won't work! 
Do you know a better solution ?
Thanks in advance!

Hi all,
i am creating a dialog like this:
CBDRMainDlg dlg(IDD_BDR_DIALOG);
dlg.AddTitleButton(<big>CBDRMainDlg::CloseDialog</big>,
IDB_CLOSE_BTN_UP,
IDB_CLOSE_BTN_DOWN,
IDB_CLOSE_BTN_OVER,
IDB_CLOSE_BTN_DISABLED);
as you can see the first parameter is a pointer to a method CBDRMainDlg::CloseDialog
the method AddTitleButton is defined like this:
typedef void (* FUNC_PTR)(...);
.
.
.
void AddTitleButton(FUNC_PTR func,
UINT idNormal,
UINT idDown,
UINT idOver = 0,
UINT idDisabled = 0,
CString szTitle = _T(""),
COLORREF rgbTextColor = BUTTON_FX_BASE_TEXT_COLOR,
enBtnState eBtnState = bsNormal);
as you can see the first parameter is a typedef of a pointer to a function.
the passed method is defined like this:
.
.
public:
void CloseDialog();
trouble is a get an error compilation:
"error C2664: 'AddTitleButton' : cannot convert parameter 1 from 'void (__thiscall CBDRMainDlg::*)(void)' to 'void (__cdecl *)(...)'
There is no context in which this conversion is possible"
can any1 help?
thanks in advanced

I bet CBDRMainDlg::CloseDialog is not static...
Thats the ususal gotcha.

hi thanks for reply
trouble is when i change the mothod CloseDialog from :
public:
void CloseDialog();
to
public:
static void CloseDialog();
i get the following 2 errors:
"...... : error C2664: 'AddTitleButton' : cannot convert parameter 1 from 'void (__cdecl *)(void)' to 'void (__cdecl *)(...)'
This conversion requires a reinterpret_cast, a C-style cast or function-style cast
Generating Code...
Compiling...
BDRMainDlg.cpp
...... : error C2352: 'CDialog::EndDialog' : illegal call of non-static member function
c:\program files\microsoft visual studio\vc98\mfc\include\afxwin.h(2610) : see declaration of 'EndDialog'"
the method CloseDialog has this body :
void CBDRMainDlg::CloseDialog()
{
EndDialog(1);
}
i know that the static method shouldn't call EndDialog.. one way to resolve that is to pass the dialog CBDRMainDlg pointer to the method CloseDialog as follows:
void CBDRMainDlg::CloseDialog(CBDRMainDlg* pDlg)
{
pDlg->EndDialog(1);
}
but if i do that, how do i send the CBDRMainDlg* as a parameter in the method:
dlg.AddTitleButton(CBDRMainDlg::CloseDialog, <====what do i pass here???
IDB_CLOSE_BTN_UP,
IDB_CLOSE_BTN_DOWN,
IDB_CLOSE_BTN_OVER,
IDB_CLOSE_BTN_DISABLED);
thanks again
Yaron

The parameter to the CloseDialog call (via your function pointer) is 'this', or do I miss something?

Hi all,
i am generating a word report using OLE Automation.It has all the things that a Detailed report can have from Header to footer.I am using mail merge to populate the data in the report.This data i am fetching from an access database.
My problem is with table of contents.The main document with all the fields contain the table of contents.This table of contents is not being merged
in the new merged document.It is displaying it like a normal text (not TOC Field) and showing values with mergefields name(not values) in the headings(the headings do have some mergefields in them).
Did anybody work on similar thing.
Please help me regarding this.

Hi,
How can I convert an int (or a double) to a CString, wich contains a hex value.
Example:
I've got an int, called 'a', with value 33.
And I need to get a String with the hexadeciaml value of 'a', wich means (in this case) that I need a CString containing "21".
Do you know wether is some fkind of function for this???
Thanks

Here you go.
As always thrown together and untested but should work.
int nValue = 33;
CString str;
str.Format("%x", nValue);
There are 10 types of people in the world
Those who understand binary, and those who don't
