Hey Guys,
Is it possible to display two fonts or more in the same CEdit control?
I need to display a price in a special format, something like this: 12.2536
Thanks in advance

No. There's no formatting information in the text of a standard edit control.
You can do it with a RichEdit control though.

you have to declare extern such variables in the header file
and define them in the proper cpp file, for instance:
extern int iGlobal;
in the header file and:
int iGlobal;
in one and only one cpp file.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

This is going to sound stupid, but I have not yet done something like that, if you could be so kind, could you please give me an example ???
Many Thanks

Thank you for the help CPallini, the explanation that you gave will also work for more than one header file and cpp file (Class - Base Classes [files]) ???

Use
/force switch in linker option.

/force sounds unwise, you should fix the problem by using extern in the headers and only defining the variables once. To see what /force does check the documentation.
I know that programming style and naming conventions are controversial, but global variables called i, n ??? How about something more descriptive?

lol, I totally agree, but when pasting an example on the CP, I don't like using the full variable name

Hi all,
Take the following into consederation:
header file
class ftp :
public ftpHook
{
public:
int ftp_FileExists(LPSTR Filename);
LPSTR ftp_StrChr(LPSTR StringPtr, char Ch);
};
cpp file
#include "ftp.h"
int ftp::ftp_FileExists(LPSTR Filename)
{
Ptr = ftp_StrChr(PathBuffer+lstrlen((LPSTR)LocalDir)+1,':');
}
</code>
But I keep receiving the following error:
Error 1 error LNK2019: unresolved external symbol "public: char * __thiscall ftp::ftp_StrChr(char *,char)" (?ftp_StrChr@ftp@@QAEPADPADD@Z) referenced in function "public: int __thiscall ftp::ftp_FileExists(char *)" (?ftp_FileExists@ftp@@QAEHPAD@Z) ftp.obj
Can anyone please help me.
Many Thanks.

Look, you make a call to ftp::ftp_StrChr [inside ftp::ftp_FileExists] but this function is not defined [it has no body]. So define that function.

hi all!!!
i have already split file by size eg. for window media format file (wmv/wma).
but now i want to split file by play length like suppose i take %age in the edit box
and it will parts that file with all equal size and remaining with the rest.
thanks in advance

The purpose of splitting is uncertain...
What's the problem? You have the file length and the persentage, so define the split position = (length*percent)/100. Or you wonder smth else?

hi! i've made a custom control button. the problem is when i click the button, the icon "disappears". when i switch to other window and back again to my app, the icon is displayed again. i think it doesnt repaint properly. here's my code in OnPaint(): It only happens in Windows 2000, not in Win XP
void CIconBitmapButton::OnPaint()
{
__super::OnPaint();
CDC* pDC = this->GetDC();
SendMessage(WM_ICONERASEBKGND, (WPARAM) pDC->GetSafeHdc(), 0);
RECT canvasArea;
GetClientRect(&canvasArea);
int iconX = 0;
int iconY = 0;
ICONINFO iconInfo;
GetIconInfo(this->m_hIcon, &iconInfo);
HDC hDC = pDC->m_hDC;
CBitmap* iconBitmap = CBitmap::FromHandle(iconInfo.hbmColor);
CBitmap* maskBitmap = CBitmap::FromHandle(iconInfo.hbmMask);
BITMAP iconSize;
iconBitmap->GetBitmap(&iconSize);
iconX = iconSize.bmWidth;
iconY = iconSize.bmHeight;
// NOTE: icon must be drawn with these coordinates
int buttonX = canvasArea.right/2 - iconX/2;
int buttonY = canvasArea.bottom/2 - iconY/2;
pDC->DrawIconEx(buttonX, buttonY, this->m_hIcon,0,0,0,brush, DI_IMAGE);
// if (m_stretch)
ReleaseDC(pDC);
DeleteDC(hDC);
iconBitmap->DeleteObject();
maskBitmap->DeleteObject();
// if (this->m_hIcon)
}

Seems there is a problem in last lines of the function. Don not call DeleteDC(hDC); the logic is that you do match a ReleaseDC per GetDC and this is all. Also you are wrapping a C++ object over iconInfo.hbmColor and iconInfo.hbmMask. These CBitmap objects are only temporary wrappers over underlying handles and thus do not call DeleteObject for them.

What I am looking to do is to provide the user (who runs my program) with a list of devices that they can pick from. You can do this with an Open File dialog if you click on "My Computer". What I want to know is how I can set up the dialog before the user opens it to prsent this list. How would you do this in C++? Have you seen it done before?
[IMG]http://i67.photobucket.com/albums/h292/Athono/_help.png[/IMG]
I want one of two (or both) solutions.
#1) I already have a custom File Open dialog program written where I am able to make sure that the user selects a directory and is not allowed to input a filename. Now I just want to know how to set up this estantiated FileOpen class so that it will first come up with the "My Computer" area showing.
OR
#2) I want to create a drop-down menu that only shows the devices for the user to pick from. In other words, just the C drive, the D drive, etc.

Sounds like you want SHBrowseForFolder

I made my own Dynamic array holder and now i want to read into it from a file i was wondering if anyone could kind of put me on the right track here is what i have.
struct item
{
char type[16];
char name[16];
unsigned int cost;
unsigned int weight;
};
int main()
{
int size;
string line;
DynArray<item> dline;
ifstream ifl;
ifl.open("items.shp", ios_base::in);
ifl >> size;
while(! ifl.eof())
{
getline(ifl,line);
dline.append(line); //line giving me errors
cout << line << endl;
}
ifl.close();
return 0;
};
I was thinking i might have to make a variable for each of them and then append one at a time. Any suggestions?
